Rock Stable system?

[Majesty]

Hello folks,

I build my Conroe system and I am trying to make it rock stable. I O/C my E6400 to 3.2GHz and tried many, many, many vCore settings from the default 1.3250 up to 1.50. I run Orthos to stress the CPUs and everytime, my system reboots after about 3h. Is there something I don't get? Is there not a fastest way to test the stability of the system? 3h is a lot of time... I don't want to get my gaming rig stable on christmas... of 2007!!

Rig:
GA-965P-DS3 BIOS F6
E6400 @ 3.2 (8x400)
OCZ PC2-6400 Plat Rev2 @ 4-4-4-12

I wonder if my RAM is not the problem. If I put the mem votage at +0.1v, my system don't boot in Windows. That RAM's suppose to run at 2.1 and it runs at 1.9 as I type this.

I'd like to have any pointers, evey bit of information is crucial!

Thank you

Try running some stress tests with your case side panel off that way you can see if the problem is temperature related. Also you should run memtest if you havent already to see if your ram is causing you the problem. I dont know much about Intel motherboards but it could be your chipset that wont do 400fsb and not your chip so you should try booting at higher and lower fsb's and see at what point it wont boot.

so what is your ram voltage at now, and what is the bios ram voltage set at?

I don't have your mobo but I've read a lot about it....you should know OCZ has problems with the Gigabyte boards concerning to memory starting voltage...so give your memory these timings and run Orthos BLEND TEST.
Timings for your OCZ at 1.9v: 5-5-5-15
The Blend TEST tests the cpu and Ram memory, how they communicate. To test system stability this is the test we all use.
If you need a faster software to test 80% of your system stability, download SuperPi 1.5 and run two instances of the 32M test. (Note: duplicate the program, I mean, do not open the same .exe twice, that will give you an error, so dowload SuperPi and copy it once to another folder so you have two Superpi .exe files and folders, ok?) This test will last less than 30 mins and will reveal if your system is at least 80% stable or not
Good Luck!

Thanks for the tips!

It seems my system is stable now. Orthos has been running for 8h now, almost 9h. I'll let it run for at least 12h, but so far, so good.

I increased the RAM's (still running @ 4-4-4-12) voltage to 2.1 and my vCore is @ 1.40. I'll try to decrease it to 1.35 and see what happens.

It's nice to have a stable comp!
