Enrickey Posted December 18, 2004 Share Posted December 18, 2004 I have a pair of CMX256A-3200C2 running in my P4P800, and today, I loaded up CPU-Z and noticed that the auto settings for my motherboard was running them at 2.5 3 3 8. So I loaded up my motherboard Bios, set it to manual and set the timings as 2 3 3 6. My motherboard was not able to boot at these settings, and even though it managed to get to the windows loading screen once, it crashed two seconds into that. I reset my CMOS and now have them running at 2.5 3 3 8 again, but I would like them to run at the correct settings. The only thing that I am overclocking in my system is my videocard, the FSB is still at 200. Link to comment Share on other sites More sharing options...
Wired Posted December 19, 2004 Share Posted December 19, 2004 Tried setting the video card back to default speeds, and then trying the memory again? Link to comment Share on other sites More sharing options...
Enrickey Posted December 19, 2004 Author Share Posted December 19, 2004 Even though videocard clock speed is set as windows is starting up (it is controlled by drivers, and it resets to default upon reboot), I tried that to no avail. It still will not boot at 2 3 3 6. Link to comment Share on other sites More sharing options...
jsteel44 Posted December 19, 2004 Share Posted December 19, 2004 Try a higher DIMM voltage, it might be running at default presently, 2.7 - 2.8V might sort you out. Link to comment Share on other sites More sharing options...
Enrickey Posted December 19, 2004 Author Share Posted December 19, 2004 I needed to set it at 2.85 before it would run at the right speed without returning errors in Prime95. Is it safe to run the memory at such high voltages? Will it decrease it's lifetime or something? Link to comment Share on other sites More sharing options...
Wired Posted December 19, 2004 Share Posted December 19, 2004 They're warrantied up to, but not over, 2.9 volts, so you're ok. Link to comment Share on other sites More sharing options...
Jabberwok Posted December 19, 2004 Share Posted December 19, 2004 Are you using the latest BIOS version for your board? Link to comment Share on other sites More sharing options...
Enrickey Posted December 19, 2004 Author Share Posted December 19, 2004 My BIOS is 10 version behind the current one, I have 1009, they released 1019 a month ago, but if it is working, shy should i risk upgrading the bios? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 20, 2004 Corsair Employees Share Posted December 20, 2004 Please make sure that you have the latest BIOS for your MB and load Setup/optimized default settings, and try the following BIOS settings; TwinX1024 or TwinX512-3200C2 Advanced/Jumper Free AI over clocking: Manual CPU Freq: 200 DRAM Clock: 400 MHz Memory or Dim Reference voltage: 2.75 Volts System performance: Auto AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!* Advanced/Chipset Configure Dram timing by SPD: Disabled/User define SDRAM CAS Latency: 2T (2.5T AMD Platform) SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 6T SDRAM Burst Length: 8 Memory Acceleration Mode: Auto USB Legacy Support: Disabled All other settings should be set to default settings! Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

Enrickey Posted December 22, 2004 Author Share Posted December 22, 2004 I figured out the problem, one of my sticks is defective, I tested it in another machine and it had the same problem. Tried another piece of RAM in the same slot just in case, and it worked like a charm. I have it sitting beside me right now in a cardboard box, what is the best thing to store it in until I can send it back? Link to comment Share on other sites More sharing options...
