Hey again..

Hey

just got round to running prime95.

Didnt go so well..the test started and then I recieved

[Feb 5 13:31] Work thread starting
[Feb 5 13:31] Beginning a continuous self-test to check your computer.
[Feb 5 13:31] Please read stress.txt. Choose Test/Stop to end this test.
[Feb 5 13:31] Test 1, 4000 Lucas-Lehmer iterations of M19922945 using FFT length 1024K.
[Feb 5 13:31] FATAL ERROR: Rounding was 0.5, expected less than 0.4
[Feb 5 13:31] Hardware failure detected, consult stress.txt file.
[Feb 5 13:31] Torture Test ran 0 minutes - 1 errors, 0 warnings.
[Feb 5 13:31] Work thread stopped.

What does this mean?

I looked for the stress.txt file but had no look finding it :S

The stress.txt file is saved in the same directory as where you ran prime from I think.

It basically means that your overclock isn't stable and its causing errors in the calculations prime is asking it to do. I take it you are overclocking?

Noep, not overclocking, all I did was change the RAM voltages and timings to what they say on the sticker :s

I dont get a stress.txt file in the directory I get prime, results and local.txt thats it :S

As already it has failed prime, what test are you running?

ran the test which tests RAM mainly

If you set them to auto/spd then try and take it from there, you might need to up the volts for 4gb, maybe an abit usef could give you some settings to try

ive upped the voltage to what it says on the sticker, you think it might need more :S

Yes, is it 4x1gb 2x2gb, you may also need to increase the chipset v

When you've done that, you might try some real life stress testing - http://forums.hexus.net/distributed-...ding-home.html

4 x 1gb

im ready to start folding when ever but cant complete WUs as i cant leave system running 24/7

Increase the RAM voltage up a notch and then try the prime test again

will do, ill take it to the next setting up..whatever that is..then test then report bk..thanks

Right PC decided to spit its dummy out.

Plaing CoD4..game stuttered..froze for a few seconds then kicked in again.

Decided to go to windows to see if anything had started..it hadn't, but then I got an error message up saying nv4 (? i think) display driver had failed so restarted, change voltage of ram to next available which is 2.20 and running prime again..it seems to be running ok but I have no idea what its suppose to look like or do when running..lol

Prime95 is now at test6 and I havent had any problems, will try game again and see what happens..

What were the settings that you used for the memory, and what speed is the memory running at?

I ask because the manufacturers tend to quote the tightest settings for the lowest speed rather than realistic settings for speeds you're actually likely to be at.

i.e. 4-4-4-12 might be quoted but it's for 600Mhz where as 5-5-5-15 might be needed for 800Mhz (just an example, I'm making the numbers up off the top of my head).

Thread four passed after test 6..

ive put the ram at 4-4-4-12 with voltage at 2.20

What speed is that running at?

CPUZ reports the following on the memory to save any more questions that i should of included in previous posts.

DRAM Frequency - 408 MHz
FSB - DRAM 2:3
CL - 4.0 clocks
tRCD - 4 clocks
tRP - 4 clocks
tRAS - 12 clocks

Command Rate - 2T

Hope that info helps

On boot now, my system now tells me that something couldnt be referrenced and can not be "written" any ideas?

Try loosening up the timings. As I said just because your memory has a set of timings quaoted on it, it doesn't mean they're appropriate for the speed you're running your memory at.

Or better still let your motherboard set the timings automatically and just up the voltage to 2.1v.

I got annoyed with the system being unstable last night so I reduced all the settings to defaults.

I will set the voltage abit higher tonight but leave the timings the same, then if its stable, ill up the timings, possibly 5-5-5-15 or something.

Also the ram is supposed to be 800MHz why would CPUZ show it as being just above 400MHz.

That sounds like a good plan.

IIRC CPUz shows you the bus speed the memory is running on, since it's DDR (DOUBLE data rate) you need to double that number to get the effective speed.

Ooops my bad on that issue.

Am Uni right now but will test as soon as I get home and boot the thing up.

God all this learning new stuff is good fun xD

Thanks for all the help Salazaar
