AMD X4 940 OC test in MSI DKA790GX-Platinum !!

[Oliverda]

Obviously the temps are not being reported correctly. Still good clocks though and if it is stable for a few hours the temps are not the most important factor. I defo think that denebs temp sensors are not as accurate as i7's.

This will also change with AM3 CPUs because they'll get the TSI (Thermal Sense Interface).

[accord99]

or i7 sensor is not as accurate as Denebs. Its all speculation so can go both ways right? what is the basis for determining which is more accurate?

Well, regardless of which one is more accurate, it's clear that the values reported by i7 and the Phenom II sensors are not comparable.

As the temp increases circuit resistance increases, more energy required to power the circuit.

The electrical characteristics of transistors vary with temperature, so I believe it's perfectly possible to have different power consumptions with different temperatures.

[amdcian]

Why did you get lower values with bigger cooler? If I'm not mistaken the power consumption doesn't depend on the cooler.

I think the bigger cooler the less voltage needed to run that clock Therefore the power consumtion should lower

With X2 5200+ Stock fan, we need 1.352V to run at 3GHz. But with XIGMATEK HSF, we only need 1.344V to run

Looks very good!

Thanks Toppc!

多谢楼主！
功耗好可观阿。。。功耗测量全是 1.25v，还是1.35?

[justapost]

Am I getting this right 88W at 1.35V and 65W at 1.25V. Good one. Thank you very much for testing, no need for other reviews now.

Here an Q9300 oced to 3GHz requires 66W.

And this includes inefficiency of PWM I'm also really happy about new C'n'Q 3.0 with more p-states and all core multiplier change. Once again I will enable C'n'Q on my RIG!!

@Toppc

I see you are running 1.6 volts on the cpu. Is it possible to go higher then 1.45 volts through the bios with Phenom II? I like my DKA790GX Platinum, but the 1.45 volts maximum on Phenom I in the bios is a bit low.

I assume it was done without ACC also. Have only read lostcircuit review. Skimmed ober anandtech, the chip has four p-states now? I'd love to tweak em all.
Think in idle it can be brought down to or close to (>5W) k8's 45w idle consumption.

@Toppc, Have you tested 1.185V with or without ACC? May work at 1.185V with ACC at -2 or 0.

Hes prolly using the AMDOD hack to get higher voltages

I don't know, if I put my X2 5000BE in the DKA790GX I can take the voltage all the way up to 1.6 volts in the bios. The 1.45 limit only seems to be there for Phenoms.

VDD 1.55V <==
VCC 1.6V

[Dennet]

VDD 1.55V <==
VCC 1.6V

That was the answer I was looking for, thanks .

Keep up the good work!

[Glow9]

how big of temp diff between stock cooler and xig? at load and idle?

[Titan7171]

VDD 1.55V <==
VCC 1.6V

so if you put a Ph2 in there those are the settings you get?? but if you put Agena in you get the 1.45v max setting??

what bios you using is that the 1.4??

I was using the 1.3 bios and all I could get was 1.45v.

1,45V limit is probably only for X4 Phenoms (I). On X3 you can also set voltage to 1,6V in the BIOS, but 1,55V or more require better cooling for motherboard power section (i.e. additional fan).

[SeLecT]

Nice tests! Good to see the difference between the coolers!

[p0inT]

What the FSB max on your MSI Platinum with you PII?
