QX9650 4.02Ghz Air Cooled Good Standing ?

lol got that to:p

[Josh]

Real temp it is and look back dan ive already said what im using nad its on and up and running results to come

[Acid_death69]

ah yerr ive seen that heatsink, Thermalright has a shit quality control, you might wanna look at the bottom of the heat sink where the metal touches the CPU. make sure it's completely flat, quite alot of them aren't if it aint flat it'll need lapping. You can easily find videos of it on youtube.

other than that it can be a very effective heatsink, i would shot some yate loon fans on it and create a push pull effect.

[Josh]

I already knew about the bottom after reading plenty of reviews mine doesnt seem to have that problem

Ive got the fan running at 500RPM and it still cooling better than stock cooler and my pc is running silent its great all fans running at 500RPM apart from GPU

I can hear agen

Right so here we go new stats with 3.60Ghz as its all i can get to run stable as high clocks seem to cause Prime95 to get errors straight away then BSOD

Stock Cooler:

Core Voltage 1.300V at Idle 1.250 at Load

Bus Speed 400 Mhz / Rated FSB 1600 Mhz

Core Speed 3600Mhz / x9.0

Temps 1-63 2-58 3-60 4-60

New Cooler:

Core Voltage 1.300V at Idle 1.250 at Load

Bus Speed 400 Mhz / Rated FSB 1600 Mhz

Core Speed 3600Mhz / x9.0

Temps 1-48 2-45 3-46 4-40

But i need help i can seem to get stable results anything above 3.60

just to add ive got 2 x 2GB DD2 800 (400Mhz) OCZ Reaper HPC at DRAM:FSB Ratio 12:10 so Memory clock is at 480Mhz ive tried setting it 1:1 seems to make no difference at all.

Maybe my volatges need increases to run a stable 4.0Ghz in Prime 95 i can get stable evevest test but prime just gets errors

HELP PLEASE

[Acid_death69]

how did you manage to get it to 4.0 before?

Yes, you probably do.
You've done the easy part- exploiting the overhead of the stock settings- so now the whole process gets much harder and infinitely more time consuming.
How committed are you to this and why?

[Josh]

I want to know the potential of my £1000 at the time CPU air cooled then watercooled

4.02Ghz was stable when using everest but when using Prime95 4th core gets a reading error.

I increased Northbridge voltage slightly and CPU to 1.44 so under load it drops to 1.40 and it runs stable at roughly 59'C until 30 minutes later the 3rd core had a reading error

Im scared if i increase some voltages i will kill something

The possibility exists.
There is widespread evidence to suggest that increased voltage chips degrade over time (which varies from @6 months to a year) and will no longer clock as high as they did when new.
This is accepted as the price one pays but then again, most of these chips are the cheap and friendly q6600 and e8400- not the top of the line extreme versions like yours.

You are putting a lot more on the line than most, hence the question about your commitment.

[Josh]

If i can achieve 4Ghz i would be happy can you help me clocker please

If temps become a problem i.e over 65'C i will increase fan speed frpm 500RPM back to 1400RPM as it makes big difference

[clocker]

Here you go.
