I know Intel recommended voltage is 1.362v for the 45nm quad. I've been running 3.5Ghz for over a year now and was able push an extra 100 mhz last week. The problem is, I'm going over the recommended voltage by a notch. I just need some of your opinion if I should keep my CPU 3.5 at recommended voltage or stay at 3.6.

3.5 Ghz @ 1.360
3.6 Ghz @ 1.376

i'm pretty sure up to 1.41v with air cooling is perfectly fine

I heard 1.45v is the absolute max and anything above 1.362v will starts to degrade. Not sure if anyone have any personal experience with this...

Degrade? What's that? This is OCN-if it boots,it's all good untill it doesn't anymore..lol!Seriuosly-you may get 2 more years out of your CPU by playing it safe,but are you really planning on using that CPU in 10 years?

It's fine up to 1.45v in the bios with LLC disabled because your load voltage will be lower. I ran my E8400 for a couple of years with 1.44v in the bios just so it was stable at 4.0Ghz (it was a C0 revision).

Actually 5 more years or so.... seriously.

I have LLC enable and 1.376v is the actual temp on CPU-Z.

If I can get 5 more years with voltage up to 1.45v then I would like to overclock my quad to 3.7-3.9. Though I don't know how much life it has left...

intel absolute max for that cpu is 1.45v, thats including vcc overshoot (voltage spikes) of .05v, so under 1.40v is fine....

1.3625v is the max VID range...

your good, go for the higher clock... .016v for 100MHz is about average...

It's fine, but if your really concerned don't bother with it. There is no way your going to be able to tell 100mhz difference. What are your temps looking like under IBT or Prime95? Your heatsink isn't the best.

This. 100 MHz won't really be felt, but 1.376 V is perfectly safe on a 45 nm. Lots of us have had our CPUs running at 1.4+ V since release.

I might try 500fsb x 7.5 = 3.75GHz... If I can get that under 1.4v then I'll keep it at that setting.

Yea I know my heatsink is not great but it does the job. Prime95 blend average is 65c max, with small FTT I reach around 72-75c. IRL gaming/performance I hardly seen it go over 62c.
