This is the most I could get out of the Q8300 with my motherboard.
Nothing amazing , but its not a good cpu for overclocking apparently.
I am happy with it and its 100% stable

Latest 3D mark vantage run with my gtx 480 pushed to max on stock cooler, hopefully i get new cooler this week or early next week
CPU is at 4ghz too, but it's nothing really, I don't wanna burn my northbridge.

My best O.C
This is my highest O.C so far. But I still prefer running my processor at it's native 2.80 GHz.

Yeah, unfortunately it seems that I have to let the BIOS auto set to voltage. I tried yesterday setting the voltage to the Normal setting (1.20) and it shut down on me after about 5 minutes. No surprise there. However, the voltage settings I have in my BIOS are set to go up 0.50v at a time, so I'm really thinking that jumping up to 1.70v would be pretty disastrous. As it is now, I'm sitting at 1.344v, which seems to be within the safe range.Not likely you will damage the chip by lowering the voltage. Changing the bclk and multiplier won't have any impact on the auto VID if the same clock speed is the result. The bios always over-compensates VID when OCing at "Auto" VID settings.
For instance, if I leave VID set to Auto, the bios runs voltage up to 1.375 to OC @ 4.0, yet if I set it manually it only requires 1.250 to achieve the same result 24/7 prime stable with a 12 degree reduction in temps.
I don't suggest you do anything you're not 100% comfortable with. Yet there's no reason to accept higher temps and excessive voltage that's not necessary to achieve the same result.

Why not try setting it to 1.35 and start testing stability. Then try dropping .05 at a time until you find the (sweet spot) lowest voltage that keeps the box stable. I personally never run VID any higher than 1.45 even for short term benchmarking. Certainly 1.70 is out of the question.

Very nice overclock!
At those clock speeds have you tested 10 hours+ Prime95 stable? It's hard to believe you got those clock speeds with a H50, what are your idle and loads temps? Are you using the stock fan that came with the H50 or have you replaced the stock fan and maybe have it in a push/pull setup from intake?
And finally, what's up with the voltage cover up?

I'm know I'm a day (days) late but.... I just want to say that the voltage range of an i5-750 is anywhere between 0.6500V-1.4000V. So, believe it or not, @ 1.20 volts, you "might" (though not likely) be over-volting! IntelĀ® Coreā„¢ i5-750 Processor (8M Cache, 2.66 GHz) with SPEC Code(s) SLBLC. Also those high volts could also lead to high temps.
BTW my i7-930's voltage range is between 0.800V-1.375V but I have my volts set at 1.1875 as it gives me the stability without high temps. And I'm slightly OC to 3.3 (3.5 turbo mode)
Just food for thought.

Stable enough to play games with load temps 68c in Assassins Creed 2 but under prime temps quickly get out of controll. I wondered the same about the voltage not showing cpu vcore was set @ 1.35000V

Have you considered a push/pull set from from intake fan(s) for your setup and maybe some Yate Loon, Scythe or Noctua fans for the push/pull intake configuration?
You will see temp drops just by moving to a push/pull setup, if you only have a push or pull single fan right now. And if you move to a push/pull setup from intake from rear push/pull that would further your temp drops because from intake you push fresh air onto the rad and pull hot air moved through the rad.

Already set up on push pull you can check out my pics on my sevenforums home page. Thanks for the tips Nemix77, I have considered a possible fan change then there is the consideration of them both matching the same rpm's.
