Bios 1253 is pretty good at keeping a constant speed, even with speedstep enabled.Quote:

Thanks Orion23. I think I'm still on 1204, I'll check it at home. I hope a new bios will fix that.
Can anyone please tell me what the hell is going on with my boards (P8P67 Deluxe) bus speed ? I have flashed both 1204 and 1253 and it keeps happening. 70mhz each time. I have used several different versions of cpu-z and aida to confirm this. My video card keeps getting a driver stopped responding error so I know that its actually running at 70mhz. I have tried changing the bus speed to 101 and 99 and it still boots to 70.
Which CPU-Z versions have you tried? 1.56.2 and 1.56.3 should fix the issue.Quote:

What does Real Temp report?
Thank you! I reset cmos and downloaded 1.56.3 and all is well again.Quote:

Yé!
Some low-volt action with batch# L040B165 .
Just a little 30-min Prime-run to check the vCore scaling. Besides, it`s good to have a low-volt option for a compact build. ;) I know everybody is pushing the other way, LOL,
2600k @4GHz(40x100) 1.14v 30-min prime small FFT :)

@ Sam. A month ago 4 Ghz with 1.114v would be impressive with the older Cpu's (actually still is). I am actually trying to get 4.7 with under 1.33 v and having a tough time. 4.6 to 4.7 GHz requires a big jump in vcore on my cpu.
Yeah, you are right :)Quote:

I will probably push it more when we know more about these CPUs, and how resilient they are with high-vCore over time.
That bump/jump seams to be around 4.5-4.7GHz or most CPUs, but it may vary depending on the batch#.
Is the 100mhz stock frequency is changeable for the 2500k on a p8p67 deluxe? Can we put it for exemple at 125*40 instead of 100*50 to get more ram speed ?
No, SBs can't do that much bclk change. However, you can get all the ram speed in the world with bclk 100.
i know than we can get all the "officials" ram speed as 1600, 1800, 1866, 2000, 2133... but can we set a 1600mhz ram to 1678 or 1721mhz for exemple?
More low-volt action, and some interesting vCore-scaling observations
4.2GHz(42x100) 1.17v 30-min Prime small FFT :)
http://img.techpowerup.org/110130/Capture025.jpg
Some interesting observation on vCore-scaling:
4.0GHz = 1.144v
4.2GHz = 1.176v
This means it needs 0.032v (1.176v - 1.144v) to scale for these 200Mhz, or 0.016v for each 100MHz.
Then, 4.5Ghz should need 1.176 + 0.048 (3 x 0.016), also it should be:
4.5Ghz = 1.224v
For 3 days ago, I testes with 1-hour prime and got
4.5GHz = 1.272v
This means, it is not scaling propositionally from 4.2GHz to 4.5GHz
There is a big gap between calculated propositional scaling (1.224v) and the actual (1.272v) vCore for 4.5Ghz. We have to cont on some error-margins too, but this gap is too big for that.
Either my CPU is turned to a Persian carpet (LoL, they get better when you use them) in last 3 days, or there is a vCore bump/jump between 4.2GHz and 4.5GHz.
I will try to test 4.4GHz tomorrow hopefully, and then 4.5GHz again, and it should answer most of it.
You can run BCLK up to about 105 or so, but beyond that it stats to get dicey. So 1600 running at a BCLK of 105 would get you 1680 on the RAM, but I don't know that it is worth the hassle/risk.Quote:

Some update on this.Quote:

There is a little vCore bump/jump @4.3GHz.
That's not a big one, but there is one for those interested in low-volt setups.
I'm still testing @4.2GHz 1.17v and if proves to real stable, then it may be a better option than @4.5GHz 1.27v for my compact setup.
I'm a bit stuck in my overclock, if someone have any interesting thoughts I would be glad. So
5.0Ghz with mems @ 933 10-11-10-28 1.65v vmem it's stable ( Linx 25 passes all )
5.1Ghz with mems @ 800 9-9-9-24 1.5v vmem it's stable ( Linx 25 passes all )
5.1Ghz with mems @ 933 10-11-10-28 1.65v get Linx error after the 1st or 2nd round..
more vmem doens't imporve it, either does Vccsa ( 0.925v ~ 1 v ) and Vccio ( 1v ~ 1.2v )
5.1 it's stable with 1.424v, I gave him a bit more and the error still shows, so any advices ?
I really want 933 mem, it takes me from 63ish Gflops to 70ish Gflops...
If @ 933 10-11-10-28 1.65v is stable @5Ghz, then it should do the same at @5.1Ghz, unless your IMC or System Agent is bugging.Quote:

I'm almost there, I just need some dahm tweek for 1T el dorado, or a better bios :rolleyes:
