-also it seems some E8500 can be found with E0 but you have to Google for the id ,saw it on a German site , but did not mark it , so they could be clearing out old C0's
-I'am waiting for the E8600 E0 myself.

I'm doubting that it is Prime95 stable at that speed, and the voltage is insane (1.60v real vcore), but apparently it's possible. This bodes well for E0 step, perhaps we will see chips that clock at 4.5Ghz Prime95 stable, with non-killer vcore.

Aigo, what was the vcore that killed your wolfie?

 

[OCGuy]

1.6V? Say bye to that one....

 

[Extelleron]

E0 stepping looks great but saying 5GHz on air is deceptive when it is certainly not prime stable. At 5GHz frequency & 1.60V, I think the temps you'd get from running Prime for just a minute would be too much even if the CPU was actual stable at those settings. And anyway.... 1.60V on a 45nm chip on air..... dead E8600 very soon.

We already see some C0 E8400/E3110/E8500 CPUs that can hit 4GHz with 1.2V and hit 4.2-4.3 with reasonable voltage, but hopefully E0 will bring more consistantly good results.

 

[Drsignguy]

Hmmmmm, I wonder if they relize that 1.6v = fubar? It says 1.6v in cpu-z...whats it set in bios? Either way, a near future keychain.

 

[Zenoth]

Such voltage... ouch. I suddenly have the picture of Half-Life 2: Episode One's Citadel's Core Meltdown/Explosion in my head.

 

[Acanthus]

suicide benching at best.

No way its stable.

 

[amenx]

Yep, its silly to present this as "e8600 can clock to 5.0 on air". Only a very few minority with the right components and a great bit of luck may achieve that. And even then with severe compromises, ie major risk of fried CPU for your next breakfast. Sadly many are taken in by these miscomprehensions, seeing an extreme overclocker doing something like that and thinking their efforts are repeatable en masse.

1. vcore will kill that chip in WEEKS not months. Trust me i killed one and i have another on loan to try to kill :T

2. This is a stepping A chip and not a stepping 6 like normal, so unless you guys have my connections, you will never own this chip. Well even if you did you couldnt own it, most likely it would be on loan and you would need to give it back.

3. Gillbot also has a stepping A chip on loan and I have a stepping A Yorkfield on loan, and its absolutely scary. Im gonna try to see how much abuse this E8500 will take which is also a stepping A.

4. Sorry 1.6Vcore IS NEVER SAFE FOR AIR/WATER possible phase. :T


Once again i'll tell you, ALWAYS TAKE ES's wth a grain of salt. Stepping A is no joke, and also NOT FOR SALE.

ES, no vcore, and no proof of stability.

:roll: 1.936v! :roll: Have to admit, great OC but absolutly CraZy voltage..

My E8500 (ES) on loan for testing is at 4.25GHz with 1.41v core and I haven't even started tweaking yet! I think it's got more in it!

I'm gonna leave it at 1.41v and see where it tops at, then bring it back to 4.25 or so and see what is the minimum stable voltage.

After that, I'm gonna try and crank the FSB and see where that celiling is. I am a shade disappointed with the hole at 450MHz though. Makes it a PIA since I can't run 450x9.

So run it @ 430-435x9.5.

 

[aigomorla]

myo ive been telling that lazy bum to do that.

OOPS.. shouldnt call my senior a lazy bum


No but seriously, he's having too much fun with that chip. Max FSB testing, MAX OC.

He's gonna get spoiled.


OH incase you guys are wondering,

I killed my first wolfdale in 1 month span under full and constant load @ 1.57Vcore. rougly translates to about 1.6V in bios. Keep note i was using less voltage that killed my cpu then what that op is doing.

Also note once again A steppings are NOT NORMAL. They just require more voltage then normal, heat up more, and clock better from my observation.

But as i said, you'll never find an A stepping for sale.

-your right I should have put a disclaimer in there , but at the time no one was listing the E8600 as a option and the only bench marks around are the suicide ones.

-as a side note , I wonder if new Quads are in the works using 8600 E0 cores ?

Interesting...I actually find it rather impressive you could get 1 month out of a 45nm CPU at that voltage.

I cringed at putting 1.6V on my 65nm Kentsfield and that was under vaporcooling. Guess I was being a bit conservative.

I assume your result was with a decent water rig?

Now where's Bonzaiduck when we could use some statistics here...if you were to double to xtors by using a yorkfield instead of a wolfdale (thus you double the opportunity for early failure) how much quicker should we expect a yorkfield to die under the same operating conditions? Is it simply half the time? (2 weeks)

 

[nyker96]

I think 1.6v is too much on even the new E0 stepping, the incremental improvement looks real but not surreal, I think those guys just used some dry ice to allow the shot be done at 6ghz/1.6v.

I've learned from being around here for 7 years...

to not post stuff like that. this isn't an extreme forum...

it's about mild overclocking and stability...

everyone will cry about how it's not stable or prime stable if you post things like that...

that's part of the reason i don't hang out around here anymore... sigh.

 

[dakels]

Are there any OC's like this with successful sustained benchmarks or are they all just for show? I wonder what the real world performance boost is at 5ghz+?

 

[aigomorla]

shimmishim..

i think i get pretty darn close with stability and not using sucide voltage.

If you want sites that care about the highest possible frequency that can boot into Windows on liquid nitrogen with voltages that cause the CPU to die within a few hours, then there are sites (xtremesystems for one) that offer you that.

I for one am not into that, I care about the performance that I can get out of a CPU that will allow stable & safe 24/7 operation on air cooling. If I can't run apps on the CPU with 99.9% stability, then it is useless IMO. Obviously you can't ensure 100% stability with any overclocked system, but if it can do Prime for 10-20 hours and Linpack 64-bit for a while, then that is good enough for me.

So far it hasn't liked much of anything between 425 and 475 fsb but I was picking frequencies at random. For now, i'll let it run @ 500. After I stretch it's legs with 500, i'll go back to the 450 hole and see what will work. Then i'm going for over 500.

heres 500 x 9 @ 1.42 vcore on my old e8400, not prime stable though:

I also have that 6426mhz e8600 SS linked in my sig.

I guess its the difference between say a nascar race... and a drag race where the cars usually blow up before they even make it to the end of the track...
