E8400 @ **4.3ghz w/ 1.39v**

What do the 2 ** represent?

The fact that it's awesome, lol.

Anyway, for benchmarking, I would go as high as the temps look OK at. For 24/7 use, however, I still keep mine below 1.36V I run mine at 3.6GHz and 1.25V all the time, I just put the 4GHz in my sig because I feel mroe important that way.

Oh
1.3625 would be my max at anytime.
I wouldn't want to be responsible for someone frying their chip if they didn't know better.
post #15 of 31
i run 4ghz 24/7 at 1.30 volts on my other computer. after vdroop it still runs at 1.27
post #16 of 31
1.36 for max oc...... 1.45 for suicide runs on water. Maybe a little more on LN2/Phase. I would say on air 1.36

Well when you overclock you flirt with risk no matter what. Even if you did decide to go over 1.3625, when at 1.3626v, the voltage isn't going to make your e8400 explode into pieces of amd debris.


The negative stigma with feeding a wolfdale voltage is bordering paranoia.

I used 1.39 on my e8400 for MONTHS! and I still use 8.5 x 500 to get 4.25ghz @ 1.34v daily and Have had zero negative effects.

In fact, I've fed my chip way more voltage than most typical users would here. I've been at over 1.6v for HOURS on a lot of days trying to get 5ghz to post into windows. Yet my e8400 is kicking and overclocking like usual. Maybe instead of SLAPL my cpu code # is R4MB0.

I can appreciate the argument from both sides of the vcore debate with the E8400. I decided to see what info is out there on this.

Anandtech: The Truth About Processor "Degradation"
Quote:
These processors are built on a new 45nm High-K process that invariably makes them predisposed to accelerated degradation when subjected to the same voltages used with last-generation's 65nm offerings. Although we certainly support overclocking as an easy and inexpensive means of improving overall system performance, we also advocate the appropriate use of self-restraint when it comes to choosing a final CPU voltage. Pushing 0.1V more Vcore through a processor for that last 50MHz does not make a lot of sense when you think about it.

I also found high VTT aka FSB termination Voltage is killing these CPUs.

Anandtech: High VTT sends our best QX9650 to an early grave...
Quote:
Let this be a warning – do not go over 1.4V maximum for 24/7 use! We are certain that the high VTT voltage and extended testing was the cause of death, as we made no other major or obvious changes within the BIOS that could have instigated a failure.

This is our first 45nm Quad core processor we managed to kill outright during testing. We hope it is the last one too. The problem is that we also have a Q9300 that is on life support after experiencing a 36-hour run at 435FSB with VTT set to 1.45V. While our experiences might not represent results elsewhere, we thought our advice to just, “Say no to high VTT” is worth a quick post. We have had enough VTT/GTL adjusting in the last year to last us a lifetime – just give us Nehalem quickly, please.

I'm at 1.38vcore and I'm just fine. Id say keep it at 1.4 or below for 24/7 running.
