Having a 1.46 vcore on 32 nm already seems severe, not sure I want to push further than this. Anyone have any long term experience at 1.475 with these chips? I dont run full load 24/7, usually only a couple hours at a clip, then it falls back to idle at 1.6 GHz and ~1.000 vcore. Not sure if I shoudl push my luck and try for the holy 5.0, or call is quite and be happy with 4.8. The electric bill may be a deciding factor in this too...
If you have Idle BSOD's, try to disable the C3/C6 reporting.

Also, If extreme works well for you, then use it. It's all about what works for each person.



Off Topic: I am not very impressed by the troll that have voted down all threads in the CPU/Motherboards section. The troll has given one star for all threads active, resulting in lower grades score for alot of the threads. Shame on you, whoever you are.

No idle BSoDs. Ive had C3/C6 disabled since day one, yet I still enjoy EIST and C1E. Ive tried upping VCCIO and DRAM voltage modestly, but it doesnt seem to help. I usually get BSODs after a few minutes of prime blend, though I do not remember the exact error code.

Also, has anyone tried the new Beta BIOS that was released july 4 for the P8P67 Pro B3? Its version 1850, and claims to improve system stability. I dont usually try beta bioses unless they have a feature I need, but I sure do like the sound of improved stability.

Every CPU scale differently with Vcore... Maybe yours is not up to the task of the 'Big' 5GHz?

Yeah, I know, I know. Im only going by how well regarded my batch number is, and how easily Ive gotten to 4.8. I know there are no guarantees, but I am not completely without supporting evidence.

I'm 90% prime stable at an offset of +.010 and fully prime stable at +.020. However I have been as high as a +.080 offset without making it more than ten minutes in prime at 5.0.

The big question is should I admit defeat and be happy its such a great performer at 4.8 and low vcore? Or do I push on in the pursuit of glory? Believe me, Im not disappointed in the chip in the slightest right where she sits now - just wondering if I should keep pushing my luck. Like I mentioned before, I'm almost more concerned with power consumption at the extra vcore than I am concerned with chip longevity. Id like to find a nice balance, but i feel like Im actually at the low end right now.

I dont want to jinx it, but I'm at 5.0 and running prime for 30+ minutes so far. Updated to the newest beta bios, upped it to extreme LLC at a + .020 offset. DRAM voltage at 1.55 and vccio is 1.15. This results in a 1.456 -1.472 vcore, and a max of 77c, but primarily upper 60s or low 70s. So far so good. Screenies at the hour mark.

BSoD right at 57 minutes! Dammmmmmit! Reducing DRAM voltage and Increasing vcore offset by .005 and trying again. Wish me luck!

Failed again, BSoD at 48 minutes this time. I really didnt see any increase in average vcore as reported in cpu-z though... Should I try and up the vcore again? For the time being, Ive gone back to 4.8...

Try upping Vcore more. These CPU's can BSOD after several hours into Blend test. They can even fail after 10 hours Blend test. Up the Vcore until you're at least 12 hours + Blend stable.

Im already seeing 1.472 vcore, but I imagine I wont be the first to try for 12 hours of prime at close to 1.5v.

Has anyone played with the CPU long and short duration power limits at all? Might be blue screening as the cpu ramps down in between routines.
