smw001 Posted October 13, 2007 Share Posted October 13, 2007 Hi, Currently I have Corsair TWINX1024-3200C2PT 1GB (2x512MB) memory in my ASUS A8N-SLI Premium motherboard (A1 & B1 slots). Can I add Corsair TWINX2048-3200C2PT 2GB (2x1GB) and end up with 3GB? I would put the 1GB sticks in A1 & B1 slots and move the 512NB sticks to A2 & B2 (ASUS says A1+A2 must equal B1+B2). Thanks for response. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 I would not suggest mixing memory with this MB, but you are welcome to try it. However, both sets of modules SPD's would have to be matched and they would need to be in the respective slots for Dual channel. Link to comment Share on other sites More sharing options...

smw001 Posted October 26, 2007 Author Share Posted October 26, 2007 Well the matched pair of 1GB sticks arrived and I removed the 512MB sticks and installed the 1GBs in A1 and B1. Everything worked fine. When I added the 512MBs to A2 and B2 the computer wouldnt boot and ASUS voice fault said memory error or something like that. Removed 512MBs and computer worked fine. The 512MBs say v5.2 and the 1GBs say v3.1. Why are the older sticks a higer version (purchased 18 mths before the 1GBs)? And do all MBs not accept different versions of the same memory? Is this a Corsair issue? Link to comment Share on other sites More sharing options...
DerekT Posted October 26, 2007 Share Posted October 26, 2007 It is never a good idea to mix and match DRAM. This is any DRAM. Sometimes it might work, sometimes it might not. It is irrespective of the manufacturer or the ICs. You asked, got the advice and went ahead and took your chances. Such is life. :) Regarding version numbers. Version numbers are applicable to the DRAM. You are looking at 512mb strips and 1GB strips and trying to compare versions? Link to comment Share on other sites More sharing options...
Yellowbeard Posted October 26, 2007 Share Posted October 26, 2007 Is this a Corsair issue? It is a characteristic of the chipset used to make the MOBO coupled with a dual channel memory controller. One factor is that is probably affecting you is that your memory configuration places a very unbalanced load on a dual channel memory controller.

Wired Posted October 26, 2007 Share Posted October 26, 2007 Why are the older sticks a higer version (purchased 18 mths before the 1GBs)?version #s are not time sensitive. Check out the first 4 digits of the lot number for manufacturing year / week. Link to comment Share on other sites More sharing options...
