kithylin Posted October 26, 2006 Share Posted October 26, 2006 Okay, first off, i have a Gibabyte GA-8IPE1000 motherboard, based on the Intel 865PE chipset, and i'm running a P4 Northwood 3.00ghz at stock settings. Over time, i've purchased first one stick of Corsair CMX512-3200C2, and played with it as just one stick by it's self, and was pleased. It worked well with my other generic sticks, compatable with about damn near anything. Later on i purchased a second stick of CMX512-3200C2, to run both in dual channel. This has worked GREAT! And has provided me with about 2 years of stable, crash-free service. But i wanted to upgrade again. This past weekend, i went to my local Fry's to find 2 more CMX512-3200C2, none of the stores in the north texas region carried any.. and i didn't want to buy online. But one store had ONE Set of this "TWINX1024-3200C2PT". Two 512mb sticks to match my other two sticks, exact same timings, but silver heat spreaders when my other two i already owned had black ones. Sadly i'm going to have to return this 1024 kit this weekend, becuase there is no possible configuration that will get these new 2 silver sticks to work with my older black sticks, it just will not boot and show POST. I've booted with just the 2 black sticks and ran cpu-z, and it reports timings of 3-4-4-8. I took out the black sticks, and booted with only the 2 silver sticks. Also the same timings reported of 3-4-4-8. Appearently EXACTLY identical timings... WHY do these 4 not work together! :( Link to comment Share on other sites More sharing options...

(As in XMS3202v5.2; XMS3202v1.1, etc.) You likely have grossly mismatched revisions of the same memory, with different IC chips. Link to comment Share on other sites More sharing options...
kithylin Posted October 26, 2006 Author Share Posted October 26, 2006 older sticks (black heat spreader) are XMS3202v5.2 (both of em) newer sticks (silver heat spreader) are XMS3202v5.2 (both of em) Link to comment Share on other sites More sharing options...
RJLeong65 Posted October 26, 2006 Share Posted October 26, 2006 older sticks (black heat spreader) are XMS3202v5.2 (both of em) newer sticks (silver heat spreader) are XMS3202v5.2 (both of em) With four sticks you will need to set the DIMM Overvoltage Control in the BIOS to either +0.2V or +0.3V. But manually change the settings when you have only 2 sticks installed, then shut down your system and then reinstall the other two sticks.

kithylin Posted October 26, 2006 Author Share Posted October 26, 2006 Thank you RJLeong65, That was the problem! This motherboard only supports +0.02v dimm overvoltage, but that was enough it seems. As i type this on my laptop i'm watching the other computer finally boot to windows with full matched corsair sticks. Very happy i am! Link to comment Share on other sites More sharing options...
kithylin Posted October 26, 2006 Author Share Posted October 26, 2006 And on checking cpu-z, it seems they run faster than previously too. 3-3-3-8 now instead of 3-4-4-8 Not sure why, maybe corsair ram is designed to run faster when all banks use corsair ram, and it works together? :) Link to comment Share on other sites More sharing options...
RJLeong65 Posted October 26, 2006 Share Posted October 26, 2006 No problem, please let us know! And remember, Corsair's DDR (as opposed to DDR2) modules are warranteed up to, but not over, 2.9V. Setting that DIMM Overvoltage Control to +0.2V resulted in an actual DIMM voltage between 2.7V and 2.8V, which is within Corsair's warranteed range.
