Does this seem OK?

So after much fiddling (I forgot how fiddly inside pc can be) I have built the new PC.

IP35-Pro / Q6600 / Tuniq Tower / 4 Gig Corsair XMS6400 C4 / Samsung 500Gb / OcUk 8800 GTX.

Currently everything is stock (not changed a single thing bar install new drivers).

Got Everest showing.

Core 1: 31c
Core 2: 32c
Core 3: 27c
Core 4: 34c

GPU Ambient: 50c
GPU Diode: 64c

I've run SuperPi once just to get a rough idea of speed (15sec).

What can I do to make sure it's nice and stable, not getting to hot (including GFX) before I even think about o/c this?

Thanks for help :)
 
About that correct voltage, mine is set at 1.8V I think (not changed anything in BIOS yet). I have a feeling the RAM should be at 2.1V anyways. How do I check that?
 
Whilst that's running - the corsair website states "tested at latency 4-4-4-12 at 2.1V" and "JEDEC standard 5-5-5-8 values at 800Mhz" so that leaves me none the wiser. Is that 2.1V o/c or just the recommended voltage...hmmm
 
Welp, I can't say that looking at task manager that Prime is thrashing my cpu's but 20mins or so of Torture / Blend temps are:

C1: 36/37
C2: 37
C3: 37
C4: 43

So that seems ok (although not sure why core4 is always 5 degress higher).
 
Right,

That thread was handy yantorsen, pointed me to the quad version of prime.

So 15mins of small fft's hitting

c1: 50
c2: 50
c3: 47
c4: 51

So bearing in mind the TIM hasn't really settled in (it's only been 5 hours) that seems reasonable..
 
That's with all system fans on low (not sure about the Tuniq fan as it's on 3pin header so I guess it's on max). Now I need to set the ram voltage.
 
That's good to hear, and even upping the ram voltage at stock to 2.1v makes everything feel snappier already.

Tomorrow I might break it and o/c a bit...
 
20 Mins at 300FSB, everything else still the same and temps are all around 50c.

I know I have the step thingy on (so when not pushed CPU-Z shows 300 x 6) but I am wondering why Core Temp shows 450 x 6?

I am trying to keep memory at 800 with dividers for the moment, so I guess just increase FSB until Prime fails and then up the Core Volts slightly and try again? Do I need to worry about any other BIOS settings for the moment?

Cheers
 
OK,

334FSB is stable at core volts at temps 54/54/50/54 (why is core 2 always lower?)

If I jump to 3.2Ghz I start to run into problems, there are a variety of Volts to adjust in bios, so I upped CPU (and RAM) by the min margin, but still get errors as soon as prime starts.

I don't really know which volts to what, and what ones I should fiddle with.
 
Currently Ram is 5-5-5-18 at 2.1V
Bios Readings
CPU 1.3250V
CPU VTT 1.20V
MCH 1.25V
ICH 1.05V
ICHIO 1.50V

So I will up the CPU Volts a tad, turn of rounding errors in Prime and try again..
 
I am at 1.3350 Volts and 3.1Ghz, Prime runs - but then has an error - not a BSOD, but errors out.

How far up should I push vcore before I up the NB Volts (is that the MCH one?)

Does it matter that my Ram is o/c slightly at this FSB.

Thanks for the help btw :D
 
What's the method to lossen timings on RAM, they are 5-5-5-18 now, do I go 6-6-6-18 or 5-5-5-20?

I could use a 1:1 Ratio, which would drop them down to 670Mhz or so...
 
Using 1:1 allowed me to pass 3.1Ghz with 56/56/52/56 temps under load.

Going to try 3.2 as the closer to 400FSB the closer I am to 1:1 Ram being a decent speed.
 
Gone back to 3Ghz for the time being with everything at normal volts (4-4-4-12) timing. Getting scared that after 3.1Ghz was getting up to 1.4050V trying for 3.2 - so thought will let things settle for a day :)
 
ok...

This is at 3Ghz so 334 X 9 (1:1.20 Ram @ 801)
CPU From Bios 1.3250V

Core Volts From CPU-Z @ idle = 1.150V
Core Volts From CPU-Z @ load = varies around 1.260V - 1.280V (occasional peaks at 1.290V)
