any chance to get the fix for D1(ES) ??
the 2600k of mine do 5200MHz HT ON rock solid 1,40VCORE (real), i think can do more but over 5200 no post eheh

[Johnny87au]

What's the max safe vCore, then? I could only find these tables, no tables similar to previous processor releases...

Quote from anand, not sure how true this statement is though

980X (32nm) chip has a maximum voltage of 1.375V
975 (45nm S1366) has a maximum voltage of 1.375V
880 (45nm S1156) has a maximum voltage of 1.400V

This means at most the safest voltage on SB will be 1.400V, but most likely well below that. I would wager 1.350V. This is why all these 1.45-1.50V 5.2ghz overclocks are only for e-peen.

Think about it...1.45V is already way out of spec for a 45nm chip, nevermind 32nm

I will be so happy if my D1 will even reach 5200, its not here yet but I will bench it hard when it arrives.

Dear Thomas,



Here you are.

Try to reach 5.4MHz this weekend! J



Attached please find the latest beta BIOS for P67A-GD65 & P67A-GD55



The 174 version BIOS update,



1. Add SATA hot plug item in BIOS setup.

2. Add Internal PLL Overvoltage ITEM.

I will test it and share it soon

[kroks]

I will test it and share it soon

neeeeeeeeeed

[@rne]

ASRock Bioses with Override PLL option are incoming.

I got a message and will test them soon

[KanGaXx]

i have overvoltage FIX PLL on my MSI but nothing changed in OC with my D1...

From the looks of it, this fix is tied to the cpu microcode. I don't think Intel will release fixes for non-retail revision ES products.

Ah crap really? ffs that sucks (since I bought one ...)

well, maybe motherboard vendors can fix it

....if not, i will use this chip for extreme daily use 5000@1,35v lol

[@rne]

ASRocks P67 Pro3 and the other Boards of them have now a new bios available on their website with the fix.

Here is my P67 Pro3 running x51.

1.55v seems crazy high and 1.45v is even high, I have read other articles saying can use low idle multiplier with 45x turbo multipler on auto voltage or just 1.3v.

Did the author of the article just go straight to 1.45v assuming that was needed or try a lower voltage first?

D2 FTW

4.8 => 5.2 with PLL overvoltage (but need too much vcore )

IIRC the 2600k's can hit like 4.0 with auto settings

[sin0822]

they can hit 4.8ghz with auto everything but multiplier. .

grr knew i was wrong lol, should of checked

Get new Mainborad

[zalbard]

Some shots of the WS board I've seen lead me to believe that it's gonna rock. Will wait for some reviews, though.

[radier]

Why on asrock page all new BIOS for P67 mobos are gone?

lol copy/read/write still better then my X58 which have been overclocked

They already make those, or they`ll be all compatible with a BIOS update?
