New System Testing Problems


Recommended Posts

We have a similar problem you addressed in:




My son built a new system and I decided to tag along and we ordered two of each. Once both systems were up and runing we both ran MemTest86 for 24 hours on each system with no errors. He was able to run 3DMark06 in loop mode for 24 hours. On my machine the 3DMark06 would crash in loop mode but would run single test or repeats up to 11 times but crashed if set to run 12 times or more or looping.


Neither of us can make it through Prime95 torture tests for both sides of the core. We have exchanged video cards and he was able to run 3DMark for a six of hours with my card but the program then crashed. I could not run 3DMark06 with his card in loop mode (Same results as with my card). If I run Prime95 from a boot disk, testing only 1 core of the processor, it runs for 24 hours.


Thinking this could be a overheating problem we re-seated the heatsink with new thermal paste on my sytem but that did not help. All (3) fans are working.


We have changed memory timings from 5-5-5-12 T1 (Recommended) to 5-5-5-15 1T and 2T but that did not work. Thinking it may be a power problem we installed a different 500w power supply in my machine with same results. We are of the conclusion that if we can not pass both of these test programs we have unstable machines and we will encounter problems down the way. Any suggestions?


Any help will be greatly appreciated!

At a glance, it seems you have been very thorough. The first thing I would suggest is to completely uninstall the Nvidia chipset drivers from the Windows/Add Remove Programs. Then, reboot and reinstall them without the Cool N Quiet driver. Also, do not install the Nvidia firewall and NIC manager.


Then, try your tests again. If you still fail, I'd suggest stripping the system to barebones, CPU, memory, and video card only, no HDs or any peripherals. Then, test each memory DIMM individually with the test from http://www.memtest.org to be sure your memory is not weak or failing. Post your results here.


I would also suggest that you have look at the MSI forums. What you are describing so far does not specifically sound like a memory issue. You may find a clue at the MSI forums.


Additionally, the programs you are using to test may or may not be accurate tests of stability. I would suggest that you load the games you want to play and torture them with those. If the systems will run the games and do everything else you try, then you have accomplished your goal.
