AKJohnny Posted January 21, 2005 Share Posted January 21, 2005 I recently bought an Alienware computer with 1GB of Corsair ram. I've been having issues with it since day one. After running a memory test it showed one of the modules to be bad. So I had it replaced under warranty. Now what they sent has a different version printed on it. I'm now trying to figure out whether it's a motherboard problem (Asus P5GD1-VM) or a problem with mixing the versions. One stick says CMX512-3200XL XMS3208v1.2 and the other says XMS3208v1.1. I am having the same problems as before except the modules are currently testing good. The computer keeps rebooting itermittantly with 2 sticks in. If I remove one, it runs fine. If the versions don't matter, I'd guess it's the motherboard, but I figured I'd check here first before I waste hours of time with Teir-1 at Alienware. Thanks for any help!

Corsair Employees RAM GUY Posted January 21, 2005 Corsair Employees Share Posted January 21, 2005 Can you tell me what you have the dim voltage and timings set to in the bios? Should be set to 2.75 Volts. Link to comment Share on other sites More sharing options...
AKJohnny Posted January 21, 2005 Author Share Posted January 21, 2005 I don't know where the dimm voltage is. Would it be called something else in the bios? I can't find any jumpers or readings on this. Maybe I'm missing something? :confused: Timings are as follows: DRAM CAS# Latency: 2 clocks DRAM RAS# Precharge: 2 clocks DRAM RAS# to CAS# Delay: 2 clocks DRAM RAS# to Activate to Precharge: 5 DRAM Burst Length: 8 Can I or can I not mix the 2 different versions? v1.1 and v1.2 Thanks for your help!

Corsair Employees RAM GUY Posted January 21, 2005 Corsair Employees Share Posted January 21, 2005 Usually the Dim or DDR voltage will be where you set the CPU Frequency and Voltage. And yes you should be able to Mix these two modules, but I would suggest you set the Rass to Cass to "3". Link to comment Share on other sites More sharing options...
AKJohnny Posted January 22, 2005 Author Share Posted January 22, 2005 I'm gonna have to wait until Monday to check again (work computer), but you say to set the RAS to CAS to 3? I thought it should be 2 since it's the low latency ram (2.2.2.5)? Link to comment Share on other sites More sharing options...
Wired Posted January 24, 2005 Share Posted January 24, 2005 Some mobos don't like the R2C delay at anything other than 3. I know what the difference is in v1.1 and v1.2, but I don't know if it would cause any problems mixing memory. However, Alienware is well known for their systems, so I would assume they tried 2-2-2-5 with that board before mass-producing it. Link to comment Share on other sites More sharing options...
AKJohnny Posted January 24, 2005 Author Share Posted January 24, 2005 Thanks for the help guys! After 2 hours of troubleshooting on the phone, Alienware is sending out another version 1.2 so that they match to see if that cures the problem. I'll keep fingers crossed. Thanks again!

AKJohnny Posted January 28, 2005 Author Share Posted January 28, 2005 Well, Alienware was supposed to send out a stick of version 1.2, but the dimwits sent version 1.1. Anyway, it appears to be working ok. It passed all the tests in Windows Memory Diagnotics 5 times, and all seems to be working fine. Apparently I received 2 sticks in a row that were defective. Very disappointing. Now the only concern I have left is, what if any performance loss can happen having one v1.2 and one v1.1 in my pc? I can only imagine that if there is some, it would be minimal. Don't know if it's worth the chance I'd take to get a matching set. Odds may be against me with 2 out of 3 being bad. :(: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 28, 2005 Corsair Employees Share Posted January 28, 2005 They should not be a problem with these modules just set the Dim Voltage to 2.8 Volts and let the bios set the timings and you should be good to go.
