P5GD2 Deluxe
OK, after looking and looking and more looking, I am narrowing down
my choices of Pentium motherboards to the Asus P5GD2 Deluxe. I don't need all the bells and whistles of the premium edition. The top performer and clearly undisputed winner in the Anand Tech Roundup and pleased to award the AnandTech Gold Editors Choice to the Asus P5GD2 Premium... http://www.anandtech.com/mb/showdoc.aspx?i=2293&p=33 What is so bad about the 915 chipset that people were/are avoiding it? Would another Asus Pentium motherboard be a better choice? Davīd Greenville, NC |

I haven't a clue why they did that. It doesn't make much sense, because as a rule, the only load on the main ATX power connector is the fan headers, for the single +12V signal. The 2x2 connector supplies the heavy processor Vcore current via two of the four pins (the other two pins are ground returns). Adding a second +12V pin via the 24 pin version of the connector just doesn't add up. Neither do the other extra pins (3,5,gnd listed in the manual) appear to be necessary, as the existing +3.3V and +5V pins were already enough for the job. This is, after all, a P4P800 board, with a LGA775 processor socket, so power requirements should be very similar to the P4P800. Hope I'm not missing something obvious there... Maybe the marketing department wanted all the P5xxxx boards to be the same :-) Paul |

If you have a good video card and DDR memory and just want to upgrade to a new Prescott processor you might want to look at the P5P800 motherboard. It uses standard DDR (instead of DDR2) memory and uses a standard AGP video card. I bought one because I wanted to upgrade my CPU but did not want to have to spend a lot of money and time trying to replace my Radeon 9700 Pro. It has a 24 pin connector but works fine with a 20 pin connector from the power supply. I bought the board, a 3.4 Prescott, and 1 GB of Corsair memory for less than $600. I had to get new memory as my old memory was RDRAM. I went to memtest.org and saw a lot of downloads.

Are you saying the 24 pin connector used for PCI Express is different from the ATX12V connector? If it is different, what should I do? Get an adapter or another power supply with the correct PCI Express connector? Davīd Greenville, NC The previous generation of power supplies (which is all I've got for my computers) has 20 pin ATX power for the main power connector, and a 2x2 power connector that feeds the processor exclusively. The previous generation of motherboards used PCI bus for add-in cards, and AGP slot for video card. If the AGP card needed extra power, that power came through a cable plugged directly into the video card. On the PCI Express motherboards, the motherboards use a mix of normal PCI slots (for backward compatibility, so you can plug in a SoundBlaster or an old modem card) and they have PCI Express slots. For PCI Express, the slot has some extra power pins, intended for handling larger current requirements. Currently, the only card that really needs that kind of power, is a PCI Express video card. I think the power coming through the slot can be up to ~75 watts or so. So, the intention was, to make PCI Express video cards draw their power through the motherboard slot, so no more auxiliary cables would need to be plugged into the cards. But, depending on the mood of the video card designers, you might still see a place for aux power connector. The situation with +12V is this. If you examine the ATX 20 pin power connector, it has one +12V pin on it. Each pin in that connector can handle a current flow of 6 amps. If you look at the new 24 pin power connector, it has two +12V pins on it. That means a total of a little less than 12 amps could flow if needed. Some of the high end PCI Express cards are drawing the majority of their power from +12V. If a card like that has no aux power cable, all the power comes through the PCI Express slot. This article has some power measurements for video cards. http://www.xbitlabs.com/articles/vid...powercons.html http://www.xbitlabs.com/articles/vid...-nv-power.html http://www.xbitlabs.com/articles/vid...00gt-oc_3.html Some of the hottest video cards are drawing 4.5 amps from +12V. The fans powered through the motherboard header draw 1 amp or so from +12V. The total could be 5.5 amps. If you only use the ATX 20 pin power connector, to power a 24 pin motherboard, then only one pin carries that 5.5 amp current. The pin itself is rated for 6 amps. All is still within spec, but the practice of drawing close to the rated current is not exactly a good one. In a situation where you are using an expensive video card like that, it may be a wise idea to either find an adapter that converts from 20 pin to 24 pin (which will take one +12V wire and connect it to two connector pins), or get a proper power supply with the 24 pin power connector on it (which will have two wires and two pins for +12V). It all depends on how you feel about drawing 5.5 amps through a 6 amp pin. So it is not a big deal. If the pin carrying the current starts to fail, it will get hot, and the plastic will start to melt. Probably by the time it gets that bad, the video card will be crashing out in 3D games. I haven't read or heard of anyone having a problem with using a 20 pin connector on a 24 pin motherboard, and if anything, it is more likely that an old power supply simply wouldn't be up to the task of driving the heavier load of a P5xxx board. On the P5P800 motherboard, which is a P4P800 AGP based board, only with a LGA775 socket for the new processors, there is little reason to be using the 24 pin power connector. That is because the board is using an AGP video slot, and any heavy power requirement will be met by plugging a disk drive connector into the AGP card. Summary: Low risk using an existing 20 pin ATX power in a P5xxx 24 pin power connector. Depending on the way it is designed, an adapter could be used, and reduces the risk further. (I wouldn't bother buying an adapter myself.) If the current ATX power supply seems unstable (due to not meeting the motherboard total requirements), then upgrade. If you do a lot of overclocking, consider a better supply. HTH, Paul |

I guess Prime95 and 3DMark are similar type test. Again, thanks Paul for your advice. Davīd Greenville, NC Asus has just about ever conceivable technology combination covered in their product line. So, you can reuse as much or as little of your existing gear, as you want. The situation with regard to the marketing of video cards, is about as poor as it can get. High end products exist in both camps, that are hard to find, and prices in some cases are $200 above MSRP. We call that gouging, where I come from. If the yield of chips is that poor, then these products are not ready for market. Period. The cards are not even carefully labelled in every case, as to whether they are PCI Express or AGP. You could consult one of the larger web sites, like newegg.com, and see what versions of cards are actually available, but for the high end cards, some of them are only available in ones and twos from the smaller retailers. This is a horrible environment to be shopping in, because it is easy to get taken for your hard earned cash, if you don't spend the time determining what the best price is. Will the situation improve ? I think the thing is, video card design is in every bit as much trouble as processor design. Will there be higher performance video cards ? Could be, but how hot will they be. Where video cards go next, depends on whether 90nm or 65nm chips are going to allow even faster cards to be constructed. SLI is a bandaid solution, and with a computer dissipating 300 watts while gaming, is not very practical. Not all games are accelerated by SLI, which means a single card is still the most compatible gaming solution. What would I do in such an environment ? Punt. Wait a bit, until video card availability improves, to get a better price. I'd be damned, if I'd waste money on a cheap video card now, and an expensive one later. That would be getting gouged twice (as the price on all video cards is higher than the tech curve). I'd do the upgrade a bit later this year. What you can conclude from that, is my personal opinion is that an AGP video card slot is still the choice _at this instant_ in time. At the rate that computer design is changing, it is really not that practical to invest in future upgradability, so find the solution that solves your problems now. A P5P800 with AGP slot would allow you to make one (expensive) AGP video card purchase now, and use it for a couple years. Where are we with technology ? S478 - dead and gone. Buy a 3.4GHz if you don't plan on upgrading. S775 - where Intel wants you. Up to 3.8GHz available. Not dual core ready. So S775 is a dead end. The writing is on the wall. S462 - AMD will discontinue this soon. S754 - AMD will discontinue this maybe this year S939 - where AMD wants you. Up to 4000+ P.R. rating. Is the socket dual core ready ? Dunno. S940 - Oh so dead. DDR - where the customers want to be. Best price. DDR2 - where Intel wants you. FB - fully buffered DIMM standard. the next generation. Introduction date unknown. The cynic in me says this could displace DDR2, but who is to say. FB is like registered RAM, and uses a buffer chip. AGP - dead and gone. Where the customers want to be, as you could get a better price. PCIE - where the industry wants you. Nvidia uses bridge chip, to convert AGP to PCIE. Which means the bandwidth of PCIE is not necessary. ATI does theirs with a native interface, and the only saving is in product cost and a bit of heat. The power envelope will limit future performance. Video cards are all about the width of memory chips on the video card, and number of pipes. The bus interface is immaterial. Chip supply constrained. Why ? Either yield, or evil gouging. BTX - Pointless case design. Irrational motherboard layout. Where Dell wants to be. All I can suggest, is buy for today, pick the solution with the best price, and let tomorrow sort itself. The very reason these technologies are being introduced, is to prevent you from having an upgrade path. As a customer, all we can do, is retaliate by upgrading less often, using the most cost effective components on the date of purchase. Memtest86 (memtest.org): This is a program that formats a blank floppy disk for you. The disk will end up with a self booting program on it, that tests all of memory. For computers without floppy drives, there is also a version suitable for burning an ISO CD. Set boot order to floppy/CD first, and let the computer boot with the disk. You can run this test, before even connecting a hard drive to the motherboard. Prime95 (mersenne.org): This program is intended to find prime numbers. As a side benefit, it also has a test of processing integrity. In other words, it can detect when the CPU isn't 100%, and it heats up the processor by running at full speed. Also seems to be effective at finding speed faults in memory (faults that memtest86 might have missed). Prime95 runs under an OS, so you run it after installing an OS on the hard drive. 3DMark (futuremark.com): Once the processor and memory are known good, you can run this benchmark. Compare your benchmark, to other comparable benchmarks, as a test that the drivers and software are set up properly. On an AGP machine, get a copy of Powerstrip from Entechtaiwan.com , as a simple way to get a listing of what capabilities are enabled on your card. (The versions of 3DMark I use, like 3DMark2001SE, have a demo mode, which can be left running overnight. If the video is stable, it should be running the next morning. Otherwise, you'll find the computer crashed or hung.) ************ Bus standards ************ Southbridge ----+----+----+----+----+----+ PCI bus | | | | | | Southbridge PCI Express | | | | 1 2 3 4 The PCI bus is a multidrop parallel bus.

Whether bandwidth/latency/cacheing issues can be solved for FB remains to be seen. Also unclear, with AMD and Intel taking different architectural paths, is when it will roll out. An FB DIMM could use DDR or DDR2 chips, as the memory chips go through a buffer chip. It is like registered memory, on steroids. And conveniently, makes more of the memory you own, obsolete.

Dear Paul
I just bought the P5GD2 . I also bought 2 sata 160GB Maxtor and I have one PATA 250GB Maxtor. I a also have to connect 2 x DVD/CD drives to the PRI- IDE 1 connector ( I presume ) How and where to plug the HDDs to the MB .?? Thanks Roland "Paul" schreef in bericht ...

As for the cash, I do not need the latest and greatest cutting edge technology as I'm not going to attempt to squeeze every bit of performance out of it by overclocking. My main reason of asking for advice from this newsgroup is to hopefully avoid problems that plague some motherboards and/or new releases.Yes, I want to spend my hard earned money wisely and get it right the first time. I was considering a full flavor Pentium 2.8 or 3.0 800FSB processor for reducing an expendure. Starting out with 512 RAM and doubling it at a later date. Utilizing the onboard audio saving the expense of a sound card. Pretty much everything else is laying around the house for use or reuse, case, power supply, hard drive, CD writer, monitor, speakers, cables, keyboard and mouse, except for the PCIe video card. Ouch! That is where I'll prolly spend more than I intended from the onset. What I want is at least 256mb. At this point, everything about the video card is undecided. Heck, I'm not certain if I should go with ATI or nVIDA. Should I purchase a value priced video card now and update later when the price comes down on the nicer video cards? Also, I'm wondering if this strategy would be prudent towards the evolving technology of the PCIe video cards. I went to memtest.org and saw a lot of downloads. Not being certain which download to select along with the apprehension of downloading anything to see what it does, I will need a bit of advice before I attempt this. I guess Prime95 and 3DMark are similar type test. Again, thanks Paul for your advice. Davīd Greenville, NC Asus has just about ever conceivable technology combination covered in their product line. So, you can reuse as much or as little of your existing gear, as you want. The situation with regard to the marketing of video cards, is about as poor as it can get. High end products exist in both camps, that are hard to find, and prices in some cases are $200 above MSRP. We call that gouging, where I come from. If the yield of chips is that poor, then these products are not ready for market. Period. The cards are not even carefully labelled in every case, as to whether they are PCI Express or AGP. You could consult one of the larger web sites, like newegg.com, and see what versions of cards are actually available, but for the high end cards, some of them are only available in ones and twos from the smaller retailers. This is a horrible environment to be shopping in, because it is easy to get taken for your hard earned cash, if you don't spend the time determining what the best price is. Will the situation improve ? I think the thing is, video card design is in every bit as much trouble as processor design. Will there be higher performance video cards ? Could be, but how hot will they be. Where video cards go next, depends on whether 90nm or 65nm chips are going to allow even faster cards to be constructed. SLI is a bandaid solution, and with a computer dissipating 300 watts while gaming, is not very practical. Not all games are accelerated by SLI, which means a single card is still the most compatible gaming solution. What would I do in such an environment ? Punt. Wait a bit, until video card availability improves, to get a better price. I'd be damned, if I'd waste money on a cheap video card now, and an expensive one later. That would be getting gouged twice (as the price on all video cards is higher than the tech curve). I'd do the upgrade a bit later this year. What you can conclude from that, is my personal opinion is that an AGP video card slot is still the choice _at this instant_ in time. At the rate that computer design is changing, it is really not that practical to invest in future upgradability, so find the solution that solves your problems now. A P5P800 with AGP slot would allow you to make one (expensive) AGP video card purchase now, and use it for a couple years. Where are we with technology ? S478 - dead and gone. Buy a 3.4GHz if you don't plan on upgrading. S775 - where Intel wants you. Up to 3.8GHz available. Not dual core ready. So S775 is a dead end. The writing is on the wall. S462 - AMD will discontinue this soon. S754 - AMD will discontinue this maybe this year S939 - where AMD wants you. Up to 4000+ P.R. rating. Is the socket dual core ready ? Dunno. S940 - Oh so dead. DDR - where the customers want to be. Best price. DDR2 - where Intel wants you. FB - fully buffered DIMM standard. the next generation. Introduction date unknown. The cynic in me says this could displace DDR2, but who is to say. FB is like registered RAM, and uses a buffer chip. AGP - dead and gone. Where the customers want to be, as you could get a better price. PCIE - where the industry wants you. Nvidia uses bridge chip, to convert AGP to PCIE. Which means the bandwidth of PCIE is not necessary. ATI does theirs with a native interface, and the only saving is in product cost and a bit of heat. The power envelope will limit future performance. Video cards are all about the width of memory chips on the video card, and number of pipes. The bus interface is immaterial. Chip supply constrained. Why ? Either yield, or evil gouging. BTX - Pointless case design. Irrational motherboard layout. Where Dell wants to be. All I can suggest, is buy for today, pick the solution with the best price, and let tomorrow sort itself. The very reason these technologies are being introduced, is to prevent you from having an upgrade path. As a customer, all we can do, is retaliate by upgrading less often, using the most cost effective components on the date of purchase. Memtest86 (memtest.org): This is a program that formats a blank floppy disk for you. The disk will end up with a self booting program on it, that tests all of memory. For computers without floppy drives, there is also a version suitable for burning an ISO CD. Set boot order to floppy/CD first, and let the computer boot with the disk. You can run this test, before even connecting a hard drive to the motherboard. Prime95 (mersenne.org): This program is intended to find prime numbers. As a side benefit, it also has a test of processing integrity. In other words, it can detect when the CPU isn't 100%, and it heats up the processor by running at full speed. Also seems to be effective at finding speed faults in memory (faults that memtest86 might have missed). Prime95 runs under an OS, so you run it after installing an OS on the hard drive. 3DMark (futuremark.com): Once the processor and memory are known good, you can run this benchmark. Compare your benchmark, to other comparable benchmarks, as a test that the drivers and software are set up properly. On an AGP machine, get a copy of Powerstrip from Entechtaiwan.com , as a simple way to get a listing of what capabilities are enabled on your card. (The versions of 3DMark I use, like 3DMark2001SE, have a demo mode, which can be left running overnight. If the video is stable, it should be running the next morning. Otherwise, you'll find the computer crashed or hung.) ************ Bus standards ************ Southbridge ----+----+----+----+----+----+ PCI bus | | | | | | Southbridge PCI Express | | | | 1 2 3 4 The PCI bus is a multidrop parallel bus. The bus is unterminated and signals ring and bounce off the ends of the bus. A bus standard tamed by determined engineering and 1000's of hours of simulation. Typically offers more slots than PCI Express. PCI Express is private and point to point. One card cannot interfere with another (except if there isn't enough bandwidth between North and Southbridge). Northbridge ----+----+----+ Memory channel(s) | | | using either DDR/ DDR2 Northbridge FB memory | | | | FB memory will be a similar improvement like PCI Express. Point to point interface, preventing interference between memory slots. DDR and DDR2 modules can interfere with one another (which is why there are speed versus number of memory slot rules, and why overclockers use one module per memory channel). Whether bandwidth/latency/cacheing issues can be solved for FB remains to be seen. Also unclear, with AMD and Intel taking different architectural paths, is when it will roll out. An FB DIMM could use DDR or DDR2 chips, as the memory chips go through a buffer chip. It is like registered memory, on steroids. And conveniently, makes more of the memory you own, obsolete.
