E8500 6GHz Benchable Club

[dinos22]

Thank you, artkobe-san.
The max Frequency pass SPI 32M is 5.9GHz without "JP Pmem Strap Tweaks".
But I cannot run 32M even 5.7GHz with "JP Pmem Strap Tweaks".....

DEWA DEWA & Good night.

what MCH voltage are you using again?
have you tried pushing it a bit more

[eva2000]

I tried two P5K and P5K-E.
They are all benchable @FSB645MHz with my WR E6700.
But their FSB limit fell down to 550-565MHz with my best E8500.....
I canot understand this situation and feel very mysteriously.

Tried GTL volt mod tweaks for P5K/-E ? I think key is in GTL ref volts for P35/X38.

Thank you m8!
I used 1.70VMCH then.
Now I use 1.75-1.77V.
But the situation is not so improved.....
I need much trial and time.

Thank you for your helpful advice, eva2000-san!
I also think key is in GTL ref volts like DFI P35 mobo.
I will search and try GTL mod for P5K.

Then I have a bit improvement of pifast.
I used before-san's setting.
Thank you so much for your advice, before-san!

This is an illusion that exists in my mind.

I discovered the p5b dlx in 2006, and you enlight it again in 2008 !! great job as always

[c1rcu1tburn3r]

Thank you always, my M8 harshal-san!


Thank you, c1rcu1tburn3r-san.
You have a great P5K!!!

Yes, i think the problem can be the new bios for wolfyes on P5K series...in fact yesterday i tried to bench again with this new bios on my 665 fsb E6850 but surprise...i found the fsb wall around 610 Mhz like on 8500... this can suggest that somethings on new bios limit our clock. You know the best bios on p5k for exaple was 0414...with another bios i reached only 5500Mhz vs 5740Mhz reached using 0414 (E6850)...maybe the situation is similar.
I tried to play with pll but nothing happened...tried from 1.5 to 1.8.
It's blocked on fsb
Do you think we can hope in a new p5k bios like old 0414?

[KTE]

Good going fellas.

GTL Ref V is needed to stabilize higher FSB/Mem straps, to remain within the narrowed margins. More important with DDR3 FSB:RAM ratios.

ASUS is know traditionally to decrease NB performance and increase it's latencies to allow higher FSB. So when benching, keep this in mind.

I am glad to still take an active part P5B Deluxe.

I think we can hope it.
Even if it is useless, some good method will be found.

Thank you for your opinion and advice, KTE-san.
Actually there are some P5K and P35 mobo that can work by high FSB with Wolfdale.
I want to know what difference are there from my P5K.....

[rintamarotta]

Insane FSB and CPU clock ..... im wordless..

[c1rcu1tburn3r]

New bios for p5k...1005,tried now. Solved my cold boot problems,now start without problems at -130°. But for other issue

NewBeetle my friend, I would love to tell you but I do not know myself
I need time to investigate the PCI hex registers but do not have free time for computers anymore

I stopped on the way, and ran 05 with E8500.

Nice WR NewBeetle-san. The 965 chipset doesn't stop surprising me. I noticed you had you northbridge cooled to -45C. Did you notice a coldbug if you got too cold? How much did that help your FSB or stability?
