C2D Overclocking Guide for Beginners

[Defenestration]

These new shots look much clearer. My vote goes to the larger ones.

[Clunk]

They are the same shots, just that I didnt let the camera shrink them, I resized them in photoshop

[EtheAv8r]

New pics are very clear.

Thanks for the larger pictures Clunk, I have highlightened them slightly and uploaded here, I hope you don't mind

Hey guys,
I pushed my FSB up to 355 @ 1.325v and 6 hours in, orthos stopped. Now I haven't rebooted since its given me this error but everything seems to be fine. What would be the cause of this hardware failure?
Temps were just below 60C according to CoreTemp.

1:Test 8, 27000 Lucas-Lehmer iterations of M2785281 using 160K FFT length.
1:FATAL ERROR: Rounding was 0.4998779297, expected less than 0.4
1:Hardware failure detected, consult stress.txt file.
1:Torture Test ran 6 hours, 15 minutes 43 seconds - 1 errors, 0 warnings.
1:Execution halted.

2:Torture Test ran 6 hours, 15 minutes 43 seconds - 0 errors, 0 warnings.
2:Execution halted.

Really nice of you to take the time to put all that together, Clunk, with that I might finally give it a go... have been seriously underwhelmed with the performance of my E6600 but can't put my finger on exactly "why"...

Thanks very much

You could try 1.350v and keep an eye on the temps. Did you enter your subtimings for the ram? I reckon a touch more voltage Have you got the ram voltage set properly as well?

[Oobie-]

Subtimings for RAM 4-4-4-12, I left the voltage for RAM on auto as I wasnt sure what voltage it should be with this 1:1 ratio.

[Clunk]

By subtimings, I mean these;

TRRD
Rank Write to Read Delay
Read to Precharge Delay
Write to Precharge Delay

probably by default, they are set to 10. Sometimes it can really help to enter the correct ones. Its worth a google to find these out, maybe somewhere like the Geil website?

If the voltage is on auto, it is very possibly on 1.8v, which is the JEDEC standard for DDR2, have a look at the specs for your ram, its probably 1.9-2.2v or something like that, so it could be that it just needs the extra bit of welly.

[Oobie-]

Ah right, the GeiL website doesn't have those timings on it.
DDR2-800@ 2.1v is what its rated at.

I'll google those headings

If its rated for 2.1v, set it to 2.1v

[Oobie-]

but its not at ddr2 800 yet, so I thought that would be overkill voltage?

[Clunk]

Try it and see. Is there anything on the sticks that says to run it at 1.8v? If not, run it at the 2.1v like it says on the label You can come back to it later and try and reduce the voltage a bit, but for now, I would feed it the 2.1v.

[daza]

Right quick question, whats the maxium amount of juice I can safely push through a E6400 for normal day to day use as I'm currently at 1.35v but usually fail orthos 3-hrs in, although Im stable in every game I play??????

[Clunk]

There is no safe limit mate, anything over stock and you risk killing it, just go for whatever temps are acceptable to you for the cooling you have.

[daza]

Well I'm never loading at anything more than 50c so that should be ok might just bring it down to 420x8 as thats quick enough.
