rbtx99 Posted February 24, 2005 Share Posted February 24, 2005 I just got a Shuttle SN85G4 V3 and tried to install 2x CMX512-3200C2PT. The system can only see 512MB. I have tried both modules individually in both slots of the motherboard and they work fine on their own. However when they are both installed the BIOS and Windows can only see 512MB. Any suggestions?

rbtx99 Posted February 24, 2005 Author Share Posted February 24, 2005 Hmmm, one of them is v3.1 and the other v1.2. I fear that this is causing the problem and I will have to send them back. By the way, I have just updated the BIOS with the latest release 31 Jan 05 and the problem remains. Thanks, Angelos Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 24, 2005 Corsair Employees Share Posted February 24, 2005 Yes, Wired is right this system would require the modules to be exactly matched. Please see if the reseller can help you with that. I would see if they will let you return these and get a Twinx set instead. Link to comment Share on other sites More sharing options...
rbtx99 Posted February 24, 2005 Author Share Posted February 24, 2005 Thanks guys, it is always sad when you have problems with a new system but at least you tracked down the reason. The good news is that the supplier has accepted return of the goods and I have borrowed a matched pair of DIMMs from work until the replacements arrive. Thanks again, Angelos Link to comment Share on other sites More sharing options...
rbtx99 Posted February 24, 2005 Author Share Posted February 24, 2005 Just a last question... the DIMMs I borrowed from work are Corsair ValueSelect VS1GBKIT400 CL2.5. Is there any benefit buying a matched pair of CL2 or should I just get the a ValueSelect CL2.5 kit which I know they work? I am told that Athon 64 works at CL2.5 and I would not benefit from faster DIMMs but I would appreciate it if someone can confirm this.

Corsair Employees RAM GUY Posted February 24, 2005 Corsair Employees Share Posted February 24, 2005 Our XMS would have a bit better bandwidth, but they would actually be runnig close to the same settings. With this MB the difference would be nominal at best. So the choice is your's but our XMS should be ablout 1-3% better memory performance. Link to comment Share on other sites More sharing options...
silentfool Posted November 29, 2005 Share Posted November 29, 2005 I have the EXACT same issue...same motherboard, same RAM, but I'm way past my return date (2 years). Since I need to replace the RAM anyway, I'm going to go ahead and replace the 512's with 1GB. Just wanted some advice on how to avoid the same error again. Should I order a kit? Or can I purchase them seperately and just check the item numbers when I go to purchase the second DIMM later? your reply would be appreciated!

Corsair Employees RAM GUY Posted November 30, 2005 Corsair Employees Share Posted November 30, 2005 its best to order a Twinx set of modules and not try and add to what you have now. If you do you would need to match the part# and revision. Link to comment Share on other sites More sharing options...
