Set VCore = 1.1000 Volt, and show us your CPU best shot !

[caater]

you can further lower voltage using crystalcpuid.
~0.8v was the lowest i could go if i remember correctly.

1.1V @ Cpuid, 1.10V @idle and 1.15V under load! 423x7 = ~3GHZ
Batch - L628Bxxx

In my case (I have a DQ6) when I set 1.2V (or 1.15V) the mobo set in fact 1.57V, which caused a huge temperature increase. In case of P5B DLX might be the same situation. I won't be repeating that to give you a screenie, as I don't want my CPU to evaporate

as i suspected, when setting too low of a voltage the BIOS goes to the top of the voltage table thus causing the higher temps that HamidFULL was seeing. my post #12 showed that this doesn't happen with the P5B-Dlx...at least not with my P5B-Dlx running 0711 BIOS.

To 3oh6 :
Thanks & nice result there !
An instant 6 C colder and it looks like both CoreTemp and Probe agreed on that too ! How can high can you OC with that 1.1000 V while remain rock stable ? Please share and your allendale production week too !

350*7 is about the max that looks to be stable, i can't spend a lot of time on it but here is a 1 hour screenshot of Orthos:


375*7 errors out right away in Orthos so somewhere between 350~375*7 is the likely stable point. CPU is an L626A453

Tanx roibm I'm true but Lestat , iamjcl , rick_fx , Falkentyne
if you have Gigabyte 965P series board you cant test it, it maybe Gigabyte issuse but it right I'm Stable with my idea
look here :

It looks like Gigabyte DS4 and DQ6 has a this problem, dunno about DS3 though, any DS3-er want to test this too ?

Fyi, from this thread alone plus from outside XS which I gathered so far, currently there are more than 15 P5B-Deluxe owners already confirmed that it works on 1.1000V stable with lower temp of course (vary from 5C to 12C ), and 5 of them were verified using DMM at PWM output. The OC speed while on 1.1V are also vary though.

That is why it will be interesting to see the result if we get enough posts on this 1.1 V result, "at least" this will give us a rough picture on Intel CPU yielding base on production week.

Rather than bored to death to watch those gazillion posts/questions like "Which week is the best ...bla..bla.." since there is no common base line to draw a consistent conclusion. Also when on high voltage OC-ing, a lot factors are affecting it such as Ram speed capability, Power supply, VMch, VFSB, cooling factor and etc.

Actually I'm planning to make & compile a graphical charts and post it here if we got enough contribution on the result at 1.1V.


To 3oh6 :

Quite an interesting result you got there, here is the comparison of your Allendale 6300 between 1st vs 2nd result :

- 1.862 Ghz : 7 X 266 -> Probe=36C, CoreTemp=32C , VCore reading = 1.06V
- 2.450 Ghz : 7 X 350 -> Probe=38C, CoreTemp=32.5C (averaged) , VCore reading = 1.06V

Wondering whether the OC temp at 1.1 Vwas really increased by 2C looking at Probe result ?

Anyway, even it was a real 2 C hotter, IMO that is still a good ratio on (CPU clock/CPU temp delta) result eh ?

[roibm]

How could he be right?

May I point out you are on the moving grounds of right and wrong?
If indeed his mainboard or BIOS is acting funny, meaning supplying 1.6V instead of 1.2, he is right, because he based his remarks on those observations alone. In this case he would have been wrong if he actually knew the mainboard was by no means supplying 1.2 but 1.6V.

Right or wrong? Should I understand that all those who agreed with the war on Iraq were wrong and should carry the responsability because their CiC lied to them?

Anyway, let's just drop it. I meant to make fun of the situation, you picked it up wrong.

[3oh6]

well said.

technically HamidFULL was correct, yes he saw higher temperatures when he set voltage to 1.1v, but before saying that lower voltage causes higher temps he should have verified that the motherboard was only supplying 1.1v when in reality it was obviously providing much much more. case closed, as roibm also said, drop it.

back on topic...

keep in mind that ambient temperature could have caused the 2C variation plus different FFT lengths in Orthos can also change load temps by up to 6-8C at times. on top of that, Orthos was running for 10 mins in the first screenshots, and an hour in the last one i posted. also keep in mind that CoreTemp will fluctuate 2-3C constantly so don't read too much into temperatures...temperatures should always be seen as a range of +/-5C and taken with a grain of salt.

I can't even boot@ 1.1 lamo!

[lowfat]

I tried running 1.1V yesterday with my p5b-d. no go. gives me a CPU overvolt error at post. forces me into the bios.

[Dave338]

I have a DS3 and started to overclock my CPU from 1,2v

Temps didn't shot 40ºC with this voltaje, so 1,1v IS LOWER!!!!!!

salu2.

My Gigabyte DS4 bumps to ~1.57V (DMM) if vCore set < 1.2250V in bios.

Exact Same problem with my DS4 we need better BIOS
I told you guys that is True!
