Hi all!
As you can see that this is my first post in this forum so be gentle for me, it's my first time I checked the Q9550 thread but last post is 4 months old so I thought that that thread is dead.
So here's the deal. I bought brand new Q9550 (E0 Revision) and upgraded my mobo from Asus P5Q Pro --> P5Q Pro Turbo (due P5Q Pro RMA).
I've read that these 45nm Yorkfields will OC good but this one individual seems not to. Before Q9550 I had E8500 which OC:ed gently over 4GHz with P5Q Pro.
Nevertheless I have only managed to get 3,7GHz out of my Q9550 (435FSB*8,5) and I have used vCore betweeen 1,25-1,35 which sounds like this chip is bad or settings in my mobo are wrong.
Heat is not the issue (Noctua NHD14) IntelBurnTest and OCCT Linpack max temps have been under 75.
Specs are here:
Q9550 (E0)
Asus P5Q PRO TURBO
Kingston DDR2 HyperX 1066MHz
(Radeon 4870).
And here is my bios settings:
I was wondering if someone with same kind of setup can help me with mobo settings. So is there anything left do or do I have to admit that 435 is max for chip. Amen?
