inSaneELF Posted April 26, 2008 Share Posted April 26, 2008 Okay, here's the issue. I built a PC using 2GB of Corsair XMS2 RAM and 2GB of some HP DDR2 RAM. The machine ran perfectly for two months. Then, out of nowhere, it wouldn't get past my BIOS loading screen. I then tried taking out the RAM and simply putting it back in and it fixed the issue of hanging at the BIOS screen. However, it would freeze in the OS, so I tried taking out the HP RAM since I figured mixing the two types might be causing the issue (plus the HP RAM is a cheaper make). The machine ran stable at 2GB using Corsair, so I decided to just pick up two more GB of the same Corsair RAM. I did that a little over a week ago and it was running fine until yesterday when the system froze in the OS and I again couldn't get past the BIOS screen. Since then, I took out two sticks and, so far, it's running stable (although it hasn't been running for too long since I took out the two sticks). Also, I should note that, before this, I tried just putting one stick of the HP RAM in there to see what would happen and it seemed to run fine. Anyways, why is it having problems with 4GB of RAM? Thank you. Link to comment Share on other sites More sharing options...
CrazyOleg Posted April 27, 2008 Share Posted April 27, 2008 Whats the part number of the memory you have and what do you have the memory voltage set to? Link to comment Share on other sites More sharing options...
inSaneELF Posted April 28, 2008 Author Share Posted April 28, 2008 It's the CM2X1024-6400C4. The voltage is set to 'auto' in the BIOS. Link to comment Share on other sites More sharing options...
Wired Posted April 28, 2008 Share Posted April 28, 2008 It's not recommended to mix memory from different manufacturers. Is this an HP OEM system? If so, have you checked the Corsair Configurator? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 28, 2008 Corsair Employee Share Posted April 28, 2008 You will want to make sure that you have the memory voltage set to 2.1 volts, and with four modules you may need to drop the memory frequency to 667Mhz to stabilize the system.

inSaneELF Posted April 28, 2008 Author Share Posted April 28, 2008 No, it's not an HP system, and I'm no longer mixing RAM. I had four sticks of Corsair and it just recently started acting up. Where do I change the voltage and frequency? Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 28, 2008 Corsair Employee Share Posted April 28, 2008 Should be under "JumperFree Configuration." You might have to set "AI Tuning" to Manual before you can change the options. Link to comment Share on other sites More sharing options...
inSaneELF Posted April 29, 2008 Author Share Posted April 29, 2008 Hmm, I tried making those changes, but I got a long beep when the PC restarted. I took one of the sticks out and reverted the BIOS settings back to default 'auto' and it's running. Again, I'm running on 3GB right now as opposed to the 2GB I was running at stable before. I guess I'll see if it freezes at 3GB with the default BIOS settings. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 29, 2008 Corsair Employee Share Posted April 29, 2008 Does the system lock up when you have 2 modules in the system with the memory voltage set to 2.1 volts? Link to comment Share on other sites More sharing options...
inSaneELF Posted April 29, 2008 Author Share Posted April 29, 2008 Does the system lock up when you have 2 modules in the system with the memory voltage set to 2.1 volts? I will try this. Any idea what the 'auto' setting is? It doesn't actually say. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted April 29, 2008 Corsair Employee Share Posted April 29, 2008 Auto is going to be 1.8v. Changing the memory voltage to 2.1 with these modules should not cause the system to fail to boot. Let us know what happens! Link to comment Share on other sites More sharing options...
inSaneELF Posted May 1, 2008 Author Share Posted May 1, 2008 Well, the system was freezing again with the 3GB of RAM at the auto voltage. I have changed the voltage to 2.10 and have not experienced any freezing yet with the 3GB. I will let you know if it occurs. If I don't get any freezing by the end of tomorrow, I'll probably try putting in the fourth stick to see if that changes anything. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted May 1, 2008 Corsair Employee Share Posted May 1, 2008 So far, so good. And don't be afraid to set the memory voltage all the way to 2.1 volts. We test these modules at 2.1v and that is where we would suggest they are run at to guarantee they are functioning properly. Also, you might try running http://www.memtest.org on the 3 modules to make sure that the system is stable in your present configuration. Link to comment Share on other sites More sharing options...
inSaneELF Posted May 4, 2008 Author Share Posted May 4, 2008 Hmm...last night when I pressed the 'shut down' button, nothing happened, so I did a manual shut down. Then, when I tried to turn it on today, it stopped at the BIOS screen again. I took out one stick of RAM, so now it's running again at 2GB.

Corsair Employee RAM GUY Posted May 5, 2008 Corsair Employee Share Posted May 5, 2008 Can you test the modules one at a time with http://www.memtest.org? Link to comment Share on other sites More sharing options...
inSaneELF Posted May 5, 2008 Author Share Posted May 5, 2008 Yes, I will try that as soon as I get a chance. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted May 5, 2008 Corsair Employee Share Posted May 5, 2008 With 4 modules DDR667 would be suggested and I would set the NB/SPP Voltage to 1.45 Volts as well. Link to comment Share on other sites More sharing options...
