SOCHOX 8GB DDR2 PC2-6400 800Mhz DIMM AMD

In an effort to exploit 4GB PC2-5300 compliant RAM, I purchased a 200 pin laptop memory module for $31 and a JET-54021 200-240 pin adapter. The RAM was tested by the vendor. I used memtest-86, Windows Memtest and the memtest app to test it. It passed all tests even after dozens of iterations. However, the PC had a tendency to crash. I had placed the adapter and RAM in the slot closest to the CPU. When I moved it to the slot further from the CPU, it crashed immediately. I conclude that the longer signal path made it more unstable. This observation may the interest to users contemplating the same idea. 4GB 240-pin PC2-5300 compliant RAM is available but it cost USD$200. I plan to wait for prices to drop. Why? I want 8GB memory without the trouble of upgrading my MOBO. Pricing on memory isn't always rational. You have to get out your pencil, and do a few calcs, to see if there's a different way to upgrade for less money. ****** Using a DIMM adapter could throw off signal integrity. So that's one unknown. You certainly wouldn't want to use four adapters on a four slot motherboard like that. Try one adapter per channel and put it in the slot furthest from the CPU or chipset. And there is actually a DRAM timing parameter which compensates for the length of the DRAM bus. I doubt your adapter threw off the dimensions too much, but I just thought I'd mention that such a thing exists. Normally, nobody even thinks about adjusting that timing parameter in the BIOS, because it's considered to be a "manifest constant of motherboard design". The motherboard designer tells the BIOS designer what value to use, and there's no incentive to change it. Paul |

I want 8GB memory without the trouble of upgrading my MOBO. Thanks for the info. Luckilly I bought a mobo (10 years ago now!) that could take 8GB of RAM. Unfortunately I've been using 8GB for about 7 years now and wish I could have more. It's really the only thing holding back my 10 year old machine in any appreciable way. Sure it'd be nice to have a faster SATA bus or PCI specification but the only thing that's really bothering me right now is the RAM limit. Oh and Firefox. When I'm gaming my PC uses about 50% of it's RAM for OS and game (Path of Exile) and plays very well. If I leave Firefox open while gaming that jumps tp 90% of RAM and the thing starts paging. Even with an SSD fitted that makes gameplay stuttery. -- Shaun. "Humans will have advanced a long, long way when religious belief has a cozy little classification in the DSM*."
