My Q6600 O/C Attempt...

[Dougiebabe2003]

Hi all,

Got my new Q6600 today and been playing with it ever since!

Bit disappointed as my VID is 1.3125v but still, can't win them all.

Specs are:

Q6600
P5K Pro
4GB OCZ Vista Gold thing
Thermalight Ultra 120A

Had problems with the BIOS earlier but all fixed now and have been overclocking for a good few hours.

So far the highest and most stable I have achieved is 3555mhz at 395x9 but needs 1.575v in the BIOS 1.488V under load in windows... 1.528v idle in windows...

Temps are 73,73,70,70 under load which is a bit high for my liking...

Surely I'm doing something wrong? I thought that 3.6-3.7ghz would have been possible with that vCore? Is it because of my VID?

Can get other voltages etc if needed.

Cheers, Doug.

hmm

Don't despair my VID is 1.325

I don't have your board but I have your cooler and I lapped my TRUE before I even started as it was quite concave. That could be a reason for your high temps.

Also that seems, to me at least, a lot of juice to be putting through the chip to get 395 x 9 but others may tell you that its fine.

For comparision as I say my TRUE is lapped, I have a 35pro board, the chip is 378 x 9 for 3.4ghz and load temps are 54-56c with 1.43v in the bios.

It would be good to post your other volts for DDR etc.

Cheers for replying!

Didn't think it was that bad but seen better VID's.

I'm thinking of giving up with getting 3.6ghz as 3.56ghz seems to be a LOT more stable and with a lot less vCore.

Will try and get it as high as I can but 70C is around the max I want to see and atm I'm seeing it on two cores.

Ambient Temp (Room Temp) is around 26C

Will give me detailed voltages etc later as I'm not resetting atm.

Temps are still a bit high as is the vcore...

Could it be that when I get to 3.6ghz it's not the cpu vcore but the NB or something else that needs to go higher?

Cheers again, Doug.

It could possibly be your other volts.

Along with Vcore I raised the DDR, CPU VTT and MCH volts in the bios. Not sure if your board will have an equivalent but most likely will.

If you haven't lapped your TRUE I can almost be certain that will be having a negative effect on your temps. Its a pain to do but worth it I think.

This was mine prior to lapping, way too much daylight.

 

[Dougiebabe2003]

Took my Thermalight off to check and it could possibly do with being lapped but that may have to wait a while

Been playing around all day and think that I have 3.5ghz stable but will be running Prime overnight.

Got it sat at 444x8 getting me 3550mhz and highest temps seen so far in Core Temp are 69,69,64,64 which I'm happy with.

Here are my voltages as they are now:

CPU Voltage: 1.5250V (In BIOS)
CPU Voltage: 1.496V (In Windows Idle)
CPU Voltage: 1.464V (In Windows Under Load)

CPU PLL: 1.62V
FSB Termination: 1.50V
DRAM Voltage: 2.10V
NB Voltage: 1.71V (Is this to high?)
SB Voltage: 1.20V
Clock Over Charging Voltage: 1.00V (What is this??)

Load Line Calibration: Enabled
CPU GTL Voltage Reference: 0.63X
NB GTL Voltage Reference: 0.67X

What I would like to know is are those voltages safe for 24/7 running? Im looking to either run S@H or fold on the chip so the PC could well be on 24/7 and if some of the voltages will kill it being on and running 100% 24/7 would like to know now.

Also how does the whole thing look? Anything to high and reckon it can be changed? I think the NB is a bit to high and could be brought back to 1.5-1.6V maybe?

Cheers in advance, Doug.

Ignore me not you lol.

I kinda messed my post up...

I was saying I have a similar board, and get similar load temps (to your original) and it doesnt fret my PC, though I'm not folding!)

With 4GB ram, you should just need to raise the NB/MCH voltage a couple of blips, ensure the RAM voltage and timings are correct and check the RAM/FSB ratio. Whats your current ratio/speed at?

RAM is at 440 DDR2 so 880MHZ and timings are 6-6-6-18.

Volts are 2.1V on the RAM.

As long as the voltages I have given above will be ok with 100% load then i'm happy for now
