Retail Q9650 Overclocking Thread

[E-mil]

I have 1,2875 VID CPU and last night past 4,9 GHz for max CPU-Z,
bench at ~ 4,8 GHz, all on air (cold air - open window) and vcore around 1,60-1,65 V

Normally for very high overclocks it's more benificial if you have a low VID as the chip is actually binned as one that requires less voltage needs for it's stock speeds. When overclocking this assists us by having a larger voltage margin for overclocking. Your 1.225v chip is not a bad chip at all, It's just not one of the very low VID chips which means that overclocking to really high frequencies would more than likely require voltages way beyond Intels safe specs.

That's what I was thinking

My Q9650 is a 1.225V VID if I remember correctly and it will do 4.91GHz at around 1.57V. It seems like it would run prime95 at 4.5Ghz and 1.42V but I never bothered to stability test extensively.(I think I did 15 minutes of prime at 4.7GHz 1.52V before the temperatures were in the high 80s. Its been too long since I tried to push it further.)

Don't be worried about a little bit higher VID.

Glad to see a 1.225 VID can go that fast

sean222, with more voltage and the right settings you can get it past 4.25.
I had a regular Q9650 and with 1.65vcore it did 4.7 and 4.8 on water and maxed out around 4.95ghz on subzero.

Yea, you're right, but my cooling is not adequate to push 1.6+ volts.

I concur, mine's a 1.2 which seems to be about the average, but it can go past 5ghz, and bench at ~4.9 on water.

ZOMG, you guys are getting amazing speeds...so it's not my VID then It's me LoL.

Actually I think it's my cooling, although I have water cooling, I only have a Feser 240 rad...AND my overclocked GTX 295 is in the loop! It generates a lot of heat that my CPU pays for I have another rad (MCR-220)...maybe I can make another loop.

Ok ok, so now that I know that it's possible to go faster, would it be safe to run at 1.5v or 1.6v 24/7? (with OK water cooling) I'm enjoying 4.25 @ 1.375, but 4.5 (24/7) was my goal a long time ago! Haven't made it there yet

Thanks
