Could it be my memory limiting me?

[phantom93]

So I'm overclocking my E6750 and it is goign pretty well. I was able to get stable at 3.4ghz but it got a little to hot one day so i went down to 3.3, I decided to try 3.4 again but I can not hit that anymore even with the same voltages I had used previously. So I am goign to settle on 3.3 and decided to d some stress tests just to check if it is rock stable. I ran Orthos Small FTT test (CPu only) and it ran fine, i didn't do it for hours just a few min, i know that isn't the proper way but I was just tryign the diffrent tests. I do the blend test and after just 3 seconds it gives me the following

Beginning a continuous self-test to check your computer.
Press Stop to end this test.
Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 3 seconds - 1 errors, 0 warnings.
Execution halted.

I think, because the CPU only test ran fien that it is my memory that coudl be the cause of this instability. However I wanted to get your guy's opinions and help. Votlages are as follows alogn with clock speeds

[Clocks]
CPU = 3320mhz (multiplyer of 8x)
FSB = 415mhz
RAM = 830mhz (Wintec AmpX DDR2 800, 4x 512mb)

[Votlages]
vCore 1.425
RAM 2.1
Nchipset 1.475
South I/O 1.6
South chipset core 1.5
VTT FSB 1.5

using the MSI P35-Neo mobo


EDIT: idk if this matter but my PCIe Frequency is 105mhz

You certainly want to keep your PCIexpress freq fixed at 100MHz. It sounds from the name of your RAM that it's rated at DDR2-800; running it at DDR2-830 is certainly overclocking it. Start by running memtest86+ and make sure you can run it through at least a couple of complete passes without errors.

'ight il ltry that out thanx

Yep, the fatal error is usually due to the memory being unstable or bad. After running memtest, tweak the memory around a bit.

hey b4 i do the memtest as i didn't haev time last night, the only option that i can change for the mem in my BIOS is the timings and the ratio. 1:1 is the lowest I can go and that makes it 830 (FSB is 415) The tiings are on Auto, could putting manual timings be more stable?

 

[phantom93]

oh i was looking at my mem timings and my mobo manual as it explains more of what the timings do, one of them idr what it was called exactly i think RAS to CAS or sumthing but anyways it says a lower speed wil lresult in better stability but a higher speed results in better performance; i can pick from 3-10dram clocks, is it 3 is the slower speed or 10? like 3 is a lower number but 10 could take longer so idk.

Yes, set it to 1:1 and lax timings to 5-5-5-15.

kk, im at 3.2ghz atm i know that im rock stable here. ill experiment later thanx for the help

your sig coonfuses the **** outa me lol

 

[Evilonigiri]

Oh really?

I'll try making it easier to read.
