Q6600 @ 3.4GHZ, Not Stable, is it safe?

TD24 · 18 Jan 2009 at 14:41

im a bit of an overclocking noob but have managed to get my Q6600 to 3.2GHZ stable. I've putted the FSB to 378, however when running Prime95 one of the core fails within a few minutes. I've done 3D Mark 06 and vantage which complete ok. my question is, is it safe to leave the processor at 3.4GHZ even though its not stable?

Whats your voltages at?

TD24 · 18 Jan 2009 at 14:46

1.3260

Ram volts?

We need a little more information

TD24 · 18 Jan 2009 at 15:01

told you i was a noob lol. i will post some volts when i get home.

Need to up your Vcore voltage. Mines at 1.375 i think.

willy · 18 Jan 2009 at 17:24

What's your vid?

What he said, try put the vCore up to 1.375. I just tried mine to FSB 380 and managed to get stable but with vCore 1.44375

TD24 · 18 Jan 2009 at 18:15

Vcore - 1.36250
CPU PLL - Auto
FSB - 1.42
DRAM - 2.1
NB - 1.41
SB - 1.150

as requested

apc · 18 Jan 2009 at 18:51

What temps do you get?

I'm running at 3.4
425 x 8
vcore 1.2000

everything else at stock
OCCT running for just over 12hrs
under load (with occt) = 76c

TD24 · 18 Jan 2009 at 18:57

28 idle, 45-50 load.

Typhoon · 18 Jan 2009 at 19:04

Up the the vcore a bit at a time, keeping an eye on the load temps. If they get into the 70's I'd be stopping there.

apc · 18 Jan 2009 at 19:16

think i will have to check my heatsink out
only 1.2v but 70+c about 40c idle

Assuming you have proper cooler, try this:

FSB 380
PCIE-E 101
FSB strap 333
Dram Freq 761
Mem timing (put what it says on the sticker on your memory)
vCore 1.4
DRAM (put what it says on the sticker on your memory)
NB 1.30
FSB Term 1.30
CPU PLL 1.50

And use intelburntest try 5 test first and watch for the temp, if it pass, try 10 test and if pass take a bit of vCore and test again, if it fail, put up vCore by 2 notch depend on your temp

That's a bit high for 1.2V?
How did you manage 3.4 with 1.2V?

SMN · 18 Jan 2009 at 21:27

From memory, im using:

Multiplier: 8
FSB: 425
Vcore: 1.375v
DDR2 Overvoltage: +0.15v
SPD Memory Multiplier: 2.4
PCI-E Voltage: Stock
PCI-E Hz: 100Mhz

(Ive got 8GB OCZ PC2-8000 running at around 1Ghz and a Q6600 running around 3.4Ghz, 37oC-42oC idle, 60-70oC at load)

fails on intelburntest and prime95 within 2 seconds of starting the test.

Started again with the heatsink
cleaned the cpu and heatsink, put on some silver 5 in a line this time not a little blob in the center
restarted windows and load = 45 to 50c

changed the clock to
bux 400 x 9
volts 1.31
2hrs with occt running load is 68 - 73c

cpu = 3.6
mem = 1066

What mobo do you have?

Try put up vCore to 1.4250 and watch the temp
