ASUS P5K Deluxe - Intel P35 Bearlake + E6600 B1 / Q6600 B3

andressergio,

I can run Prime95 blend at 6x525FSB, but same as you - two cores are gone. I don't think there is a lot we can do about it. I usually only run 400-425FSB day to day so I am not really worried.

Well last night i did an OC session to test if i can get it Prime95 stable under vcore=1,5

I tried the RLM settings:

With this settings i made it stable, tried 446 and failed after 10min...so that indicates that it needs more vcore, no matter the other settings, just vcore seems to make it Prime95 stable...

I also tried with this:

************************************************** *******

CPU Voltage: 1.475v

South Bridge Voltage: AUTO

But same situation, I can go up if i don't raise vcore

Some observations I made:

Cores IDLE, the first 2 ones have no difference in temps, the third has like 7C difference...and 4th has 2C. At full load the difference is like 4 or 5..I had the CPU lapped and happened almost the same before i did the lapping...Maybe it's the Big Typhoon push pins that are not fitting well or maybe the CPU it's just like that....I also applied the AS5 spreading with a card, i don't knwow if the AS5 is the best method...the one on AS web site...

Any help will be appreciated

Yes I have the same... except my 4th core is only 1 or 2°C hotter than the third.

When you say fails prime, small ftt or blend?

maybe try setting trtp to 8, seem to remember that coming into play for someone else over on i4memory.com.

Also the other auto settings. I would have a look at what memset is reading, and maybe try loosening up some of these. Like twtr, write to precharge etc.

I've had situations on the DFI where small ftt ran a lot longer than blend, indicating memory was causing the problem.

probably way off, but just a longshot.
