Lenovo T500 ram
Hi all ;
I'm not a techie - be gentle .. :-) I'm considering a ram upgrade for my trusty old T500. core 2 duo P8400 @ 2.26 ghz Presently Win 8.1 Pro originally Vista with 2 + 1 ram. I recently installed a SSD which worked great for improving start-up and shut-down - but I'm wondering if I can expect any more performance improvement with 4 + 2 ram ? or 4 + 4 ? maximum I've read that it should be 2Rx8 not 1Rx8 ? Not wanting to spend a lot of money - but I really like this computer - it's perfect for my needs. Any suggestions ? The new ram that I see does not mention 2Rx8 or 1Rx8 - the used ram has it shown on the sticker photos .. Here's what I'm thinking of trying : https://www.canadacomputers.com/prod...item_id=039721 Used 4 gig PC3 laptop sticks seem a bit rare in my area and run ~ $ 30. John T. |

Here's what I'm thinking of trying : https://www.canadacomputers.com/prod...item_id=039721 Used 4 gig PC3 laptop sticks seem a bit rare in my area and run ~ $ 30. John T. There are two pictures for this product. One with 16 chips per module (old picture). One with 8 chips per module. F3-12800CL9S-4GBSQ Buy it from some place that allows "returns on error". The Crucial also looks like a high density config. They swear on their mothers grave it's compatible and everything. https://www.crucial.com/compatible-u...ad-t500-series We'd need the datasheet for the GM45, and the text in the memory section, to dispel uncertainty. The datasheet 320112 is *not available*. This puts me in a bit of a spot, playing density roulette for you and so on. As long as your vendor is an "allows returns" company, you're in good shape. Note that CanadaComputer made some change recently to their policy, and you might want to hunt down the details of that. So far, by appearance, both the Crucial and Gskill look dodgy. ******* Consider this thread for a moment. OP gets in trouble using a particular Gskill product. https://forums.lenovo.com/t5/ThinkPa...3784569?page=2 In the very last posting in that thread, the OP in the thread tries some "Macintosh" memory. And the picture here shows it is low density stuff. Things that make you say Hmmm. I love bargains. I hate surprises, especially getting boned on density errors caused by greedy manufacturers (as soon as the high density chips are a dollar cheaper, they change manufacturing format on you). (Unavailable, well who is really surprised at this...) https://www.amazon.ca/G-Skill-1066MH.../dp/B003QLHJFE I would probably phone Crucial, if going with their matched pair product, and see if they agree the machine should be getting low density. And double check that unlike the Crucial product picture, the stuff really is low density 16 chip. Since the CanadaComputer, you can phone them and ask them to look at the product, they should be able to quickly confirm they carry the newer 8 chip SODIMM and not the older 16 chip SODIMM you wanted. Sometimes chipsets do work with high density RAM, and there is always the possibility the datasheet never truly represents how the hardware works. (That happened on my VIA chipset motherboard with DDR2 memory. It worked with 2GB sticks, but the VIA webpage said "No".) It's that forums.lenovo.com thread that's bothering me. Now I need an antacid :-) Paul |

John T. https://download.lenovo.com/ibmdl/pu...43y6630_03.pdf Page 48 gives the memory configuration. Looks like 4 GB is as much as you can install whether it be one 4GB module or two 2GB modules. That's for "standard memory", whatever that means. There is a row in that table for "optional memory" that shows another 4GB module can be installed, so you could have 8GB in that laptop. Are there really 3 slots for memory, or just 2? If just 2, looks like you can put in two 4GB modules: one in the "standard" memory slot, and another in the "optional memory" slot (I'm assuming the 1st slot is "standard" and 2nd slot is "optional"). Page 70 shows where to install/change memory modules. If you use only one 4GB module, it goes in Slot-0 (lower connector). If you use two 2GB modules, one goes in slot-0 and the other in slot-1. There is no mention of where to find the "optional" memory slot. Probably have to remove an access panel on the bottom. However, you may not have that feature. An online copy of the manual is found at: https://www.manualslib.com/manual/78...page=58#manual Page 58 is where memory change is described. "Optional memory" just seems to refer to the standard memory module compartment where there at 2 slots where you can use 1 module (lower slot-0) or 2 modules. That laptop apparently has a limit of 4GB addressing, so you can put one 4GB module in slot-0, or two 2GB modules in both slots. Specifications in that manual do not state the maximum memory capacity. That's why I found the hardware servicing manual which indicates 4GB total. http://www.notebookreview.com/notebo...inkpad-review/ That mentions "... gain access to an open WWAN slot, another for Turbo Memory or UWB, two DDR3 memory slots, ...". So, there are the two SODIMM slots, but maybe there is a smaller card slot to add something like an SD card. "Turbo Memory" is mentioned at: https://support.lenovo.com/us/en/solutions/migr-71355 On that page, it mentions "Intel Turbo Memory Minicard". Found it described at: https://en.wikipedia.org/wiki/Intel_Turbo_Memory Sure sounds like an SD flash memory card. Those will be a *lot* slower than your main or system memory on the SODIMM modules. Found some pics in an image search: https://www.google.com/search?tbm=is...y%20minicar d Nope, that isn't an SD card (other format flash memory card). That's a special card you have to buy (but your description indicates you already have one that adds 1GB). https://www.newegg.com/p/0RN-0013-00...&source=region $70 for a 4GB minicard. Sorry, I couldn't find specs from Lenovo saying what is the maximum size that laptop will support. You sure the minicard slot isn't already populated with a wifi card? Seems to be the majority use for that slot. https://www.crucial.com/compatible-u...ad-t500-series That indicates you could have 8GB in the laptop, but Lenovo's servicing manual indicates 4GB is the max. You could buy their 8GB 2-module kit to see if those work. Check Crucial's return policy before buying. Since you hint you already have 4GB in the laptop, and assuming that is with one SODIMM and not with two 2GB SODIMMS, you could buy just one 4GB SODIMM. Because architecture can differ, I usually buy the memory modules in sets where all are the same type from the same source. I've found other memory vendors claiming the T500 can take 8GB (two 4GB modules). If it takes 8GB, don't bother changing out the 1GB memory minicard. While you can add more system memory to reduce the chance of using the pagefile which is on the slower drive (although you said you replaced that with an SSD), you could also review what processes are running memory, get rid of some, and free up some RAM. You may not really need all those startup programs eating up memory. The SSD will give you the most noticable speed boost for boot and loading programs. You may not notice any boost going with more memory. |

" The OPs chipset is GM45, which is a mobile mainstream northbridge with built-in graphics for a laptop. The GS45 is likely to be a tablet config (where memory-down, soldered to motherboard is the thinnest option). The GM45 should be one double-sided SODIMM per channel. 4GB each. 8GB max. There should be two SODIMM slots and zero memory-down. The memory map for the chipset extends to 64GB, so there isn't a "clipping problem". The lenovo forum thread I was reading, I was worried that perhaps clipping was the problem. To allay that fear, I looked at a P45 datasheet and could see the memory map extends to 64GB decoding. The above GM45 datasheet shows the same sort of diagram on PDF page 43 (rotate page 90 degrees to read it). It still looks like those nice-looking "Mac modules" mentioned, the ones with 16 chips would work. The various descriptions of system memory, use 16 chips which are x8 bits wide, and those are the two ranks of the 4GB module. If you botch that part of the operation, you would likely get half the memory capacity of the stick. When the density is botched, I think the seoond half of the memory is inaccessible (no pattern on the address bus, will get you there). Paul |

No one wanted the high-density modules. There was a very limited market for them back then. The Lenovo servicing manual that I found listed the memory modules supported, so I'd look at those to see if they were high- or low-density. Since the servicing manual doesn't say anything special about the memory modules regarding density, and because the Thinkpad T500 was introduced back in 2008, my bet is on low-density modules. Because the key notch varies based on DDR spec, the pin count varies, and to make sure I got one(s) that work with the computer, I'd just go with Crucial's recommendations (even if you buy elsewhere). Newegg has a memory finder tool, too (although "laptop" wasn't listed as a category, so I had to use "notebook"). https://www.newegg.com/tools/memory-...title=4%2520GB Prices are high, but some are low. I selected Corsair and Crucial for vendors. Up to you if you want to pick some others. Peculiarly, Newegg lists the same product (CT51264BC1339 from Crucial) from $189 down to $21. Alas, their memory finder tool doesn't let you select the seller, and I rarely buy from 3rd parties using Newegg as a frontend etail store and instead much prefer to buy from Newegg (because you deal with them, their return policy, and they often provide some support). None of the search hits were sold by Newegg. All were Chinese sellers. Don't know from they're shipped, but Crucial's own pricing was on the low end. |

I would think the manual or servicing manual would indicate if high-density were required. The high-density issue is a measure of Intels ability to figure out in advance, the rate at which the memory industry will advance. There are at least three generations where they got this wrong, and it's a safe bet they'll get it wrong again. The "user manual" is only as good as Intels advice to designers. It would be cheeky for a user manual to say "product uses X, but we think Intel will get it wrong again, and you will need low-density RAM at the 2X product level". Another galling aspect, is when companies like Kingston and Crucial get these things wrong, and stock the wrong RAM on purpose. The "on my mothers grave, this product is compatible with your computer" deal. They erode my trust in them enough, I'm prepared to send people to Ebay as a more trustworthy source. With Kingston, they were so certain of the details of their business, they provided "datasheets" with a drawing of both sides of the DIMM. This made it easy to examine the data for a SKU, and tell people "this one will work, I have the datasheet". And then one day, Kingston started shipping 8-chip DIMMs for a product with a 16-chip diagram, and now all I can tell people is "I have datasheet, have you been to casino lately?". By not sticking with the datasheet-specified design, that completely wrecks my trust in them. Potentially, a person could go to the computer store, pick up two single-DIMM packages... and end up taking home an 8-chip and a 16-chip DIMM in the belief they were a "matched" pair. Paul |

I selected Corsair and Crucial for vendors. Up to you if you want to pick some others. Peculiarly, Newegg lists the same product (CT51264BC1339 from Crucial) from $189 down to $21. Alas, their memory finder tool doesn't let you select the seller, and I rarely buy from 3rd parties using Newegg as a frontend etail store and instead much prefer to buy from Newegg (because you deal with them, their return policy, and they often provide some support). None of the search hits were sold by Newegg. All were Chinese sellers. Don't know from they're shipped, but Crucial's own pricing was on the low end. Thanks - I ordered the one from Canada Computers - it matched one of the compatible units in the newegg finder. They will take returns normally 15 days but extended for covid-19 John T. |

Unless you are using the 64 bit version of the OS (which I doubt)
only about 3.2 gigs can be utilized, so going over 4 gigs will be a waste of money. |
