Recommendations for board for video editing.
I'm figuring out what kind of parts I need to get, but could use some
help. The last system that I worked on building was a, ahem..., P-75... weak grin Lots has changed since then... I want to build a system for editing home video type things. So far I know I want a motherboard with 800mhz FSB, Dual Channel Memory, Intel chipset, NO integrated video/audio, SATA capable and able to run 4 or more Gigs of RAM. I'm not looking to overclock anything, or do any "tweaks". Just want reliable and reasonable performance right outta the box. What other requirements should I be looking for??? Thanks in advance. -- - Rog http://www.wpcusrgrp.org/~rogerbuchanan/index.html NOTE: to Reply to this, remove the phrase "NOSPAM" from my "Reply To:" address, or it will be returned. |

When you say "4GB or more", this is the limit for 32bit CPUs, if you think you may be requiring more RAM you should seriously consider a 64bit system, which can handle insane amounts of RAM. |

He's going to need more than XP Professional too. If you're serious about performance, get a Dual CPU board, 4GB of RAM, and at least 3 hard drives - two act as a MIRROR for the OS and source files, the third is the one you write the final video to while reading the parts from the mirrored set. This gives you the redundancy to keep the system running and a alternate drive that permits the heads (r/w) to move without having to reposition while reading the source. A Dual Xeon system with Windows 2003 Server Standard would scream in this setting. XP Prof does support the RAM and CPU's, but it will only see 2 CPU's, not 4 if you have Xeon's - since HT makes it look like 2 CPU for each physical one installed. http://uk.asus.com/prog/spec.asp?lan...PC-DL%20Deluxe -Supports Intel Xeon processor with 512K cache up to 3.06GHz+ -Supports 533MHz FSB -Supports ECC/Non-ECC based 128MB to 4GB memory capacity -Promise PDC20378 Serial ATA controller -Supports 2 x Serial ATA ports and 1 x ATA133 channel -Supports RAID 0, 1, 0+1 function. Also support RAID function across Serial ATA & ATA133 channel -2 x ATA100 IDE connectors, 1 x ATA133 IDE connector -4 x Serial ATA connectors It has o/b sound, but I'm sure this can be disabled in BIOS |

I guess my first question would be whether a video editing program can actually use all that RAM. Perhaps Photoshop could make use of it, for very large images at high DPI, but I would think that video simply wouldn't benefit. I mean, if you had enough RAM, at some point you could hold the entire clip in memory, but how much memory would it take to hold a couple hours of video ? At some point the video is staged on a disk, for input or output, and there really isn't any advantage to holding a lot of the clip in memory. First, you should do some checking as how much RAM people buy, for use with the same video editing suite you plan on using. Maybe you'll find that 1GB is enough not to limit performance. There are limits to both program design and OS design, as to how much memory an individual program can use, and what the split is between the OS and userland. For example, with no modifications, your average OS would give 2GB OS and 2GB programs. With a command line switch, some can be convinced to do 1GB OS and 3GB programs. Then the program itself has to be compiled to handle a 3GB space instead of 2GB. The bottom half of this post is where I learned about some of this: http://groups.google.com/groups?thre...0uni-berlin.de In terms of motherboards, the P4C800/P4P800 use 875/865 chipsets, and have four DIMM slots, for using 4GB of memory. But, the PCI and AGP devices need some address space, in order for the processor to access them, and this address space comes at the expense of main memory. You lose a portion of main memory as a result. Typically, you might see 3.5GB of memory available, when plugging in four 1GB DIMMs. The latest series of motherboards P5xxx, use the 925/915 chipsets. These also have four DIMM slots, and depending on the motherboard, use DDR or DDR2 memory. They have the same issue with memory space, but because the boards now include PCI Express card slots, even more address space is wasted, at the expense of main memory. Using four 1GB DIMMs, you might see 3.0GB of memory available. See section 2.2.1 of these two Intel motherboard manuals, for details on where the numbers come from: ftp://download.intel.com/design/moth...z/C3176501.pdf ftp://download.intel.com/design/moth...v/C6859701.pdf In terms of performance, you might be thinking that buying 2x1GB plus 2x512MB DIMMs would be the right solution. If you do that, you can lose 20% memory bandwidth compared to 4x1GB DIMMs. So, depending on whether this computer is for a home business, the economics of your time might dictate buying the more expensive memory configuration, even if some of it is thrown away. This was detailed in an Anandtech article: http://www.anandtech.com/memory/showdoc.aspx?i=1839&p=6 If this is a home business, you might also consider hardware acceleration for video editing. The main benefit of acceleration hardware, is it can do format conversion for the output process, so you aren't limited by the performance of the processor for whatever form of compression the format uses. The hardware is also capable of doing some acceleration for simple transitions, but many of the effects also rely on the processor for assistance, so you don't get complete hardware acceleration. These cards can be expensive, like $3000+, but if you are serious about your platform design, might be work looking into. http://www.canopus.us/US/products/In...duct_index.asp (DVRex) There are also some drool worthy motherboards on the following web sites, but it may be hard to take advantage of them for other than server type applications. The software would be the limitation he http://www.tyan.com/l_chinese/products/html/matrix.html http://www.supermicro.com/products/motherboard/matrix/ HTH, Paul |

The maximum amount of RAM that consumer motherboards can use is 3 GB in
essentially all cases. -- DaveW "Roger Buchanan" wrote in message ... I'm figuring out what kind of parts I need to get, but could use some help.

I have been using 2 x 512Mb (PC4000) and 2 x256Mb (PC3200) in my PC-DL (Intel 875 chipset)mobo. This is because my backup system will no longer boot with the 256Mb sticks (TwinMOS) so it has 2 x 512Mb installed. I removed the 2 x 256Mb sticks and the AIDA32 memory scores went by over 20%. I was going to buy some 1Gb sticks (one now and another later), but I shall now rethink that strategy. It looks like it may be two more PC4000 sticks. -- Doug Ramage [Watch Spam Trap] |

Except all the ones that have 800Mhz FSB and will take 4Gb like the
P4P80XXXX's. That said, you don't need that much memory for video work. For the best advice you can get pop over to rec.video.desktop they are a friendly bunch that will clear up your misconceptions and point you in the right direction. Cheers.

Pete D I agree with the second part of the post, but your first point needs some elaboration. An 875/865 based board happily takes 4x1GB sticks, but there is an address space problem. The Northbridge is limited to a 4GB address space, and from that space, you need to address PCI cards, the AGP slot, and the memory you just plugged in. The PCI and AGP cards might need 500-700MB of address space, and that must be subtracted from the 4GB of DIMMs. There is a register in the Northbridge called "top of ram" or the like, and the BIOS programs it, such that there is room for PCI and AGP. You cannot access memory any higher than the setting of that register. Paul "DaveW" wrote in message news:nmXdd.168086$He1.68907@attbi_s01...
