Phenom II 940 + LN2 at PCLab.pl

[G.Foyle]

Hello, it's Yotomeczek and me again!
We had another benching session after hours at PCLab.pl, this time with LN2 and Phenom II sample.

rig:
- AMD Phenom II 940 week 41
- ASUS M3A79-T Deluxe voltmodded
- G.Skill PI 2x 2GB 800-4-4-4-12
- Corsair Dominator 2x 1GB 1250-5-5-5-18
- ASUS GTX295
- Thermaltake 1000 W PSU
- Yotomeczek's single stage and LN2 pot - both by Ryba

Max MHz:


Max PI 1M:


Max Wprime 32m:


And max PI 1M on SS:

Pot full of LN2:


Some observations:
- with HT Link Speed under 1000MHz there are no signs of coldbug
- with HT above 1000MHz CPU coldbugs around -55°C
- any benchmark longer than SPI 1M was almost impossible to get stable - I think motherboard might be the problem
- CPU scales with cold rather than with voltage. Anything above 1.85 V shows no improvement at all with LN2 (1.61V under SS).

After all, we were a bit unsatisfied with low stability at longer benches, but nevertheless happy We're not finished with Deneb, retail CPUs are coming
Big thanks to Bruno from AMD for sponsoring our LN2!

hmm, nice to see another action from polish guys


Now, lets wait for me scores with ln2

[Morais]

Nice cloks and great timing on wPrime, congrats

[biohead]

week 41 ... you just need a newer chip. no coldbug, better clocks.

In that case I have really gem cpu from 41 week

[redratamd]

Wow ,it's a very fast run for Vista ?
Nice clocks here

[Pt1t]

In that case I have really gem cpu from 41 week

me too, 5.4Ghz under -100° :p i will test test under ln2 this week.

[ryba]

Yep, but what max HT/HTT you had on this -100?

[Lightman]

Very nice clocks and scores guys!!
It's always nice to see full pot of LN2

Waiting for your retail Deneb scores

[tiborrr]

Nice start, Polish friends! I am anxious to see more results

[Borys]

Very nice i'm waiting for more :P

[Bullet92]

Really nice start with Deneb and sure that you're not finidhed with it. There's some place to better result under ln2 and I wish you guys good luck. Nice to see POT full of LN2

[PakaPaka]

nice

what is the stock speed of this cpu?
i don't fine he's default stock speed
