It's benchable of course, but I testing yet
Ok. So my E8400 is stable at 4000 Mhz on 1.26 Vcore. I'm having trouble going over 4000 though. The problem is that I can't seem to stabilize a 4200 Mhz overclock on any voltage up to and including 1.31 Vcore. The other issue I'm having is that no matter what setting I change in the bios, whether it be the VID or the VID special add, the voltage won't go above 1.31 until I hit a spot at around 1.34 Vcore. WHen I got it to finally boot at 1.34 and tried to run stress tests, I got BSOD within a few minutes. Any suggestions? Also posted this on the DFI x48 page as well.
Here are the settings I was usiing for 4200 Mhz
Vcore - 1.34 - (CPU VID @ 1.2375 + VID Special add @ about 108.2%)
CPU VTT 1.2
NB volts - 1.405
SB Volts - 1.65
VDIMM 2.1
Ram timings - 5-5-5-18
A lot of e8400's can't hit 4.2ghz at all unless you go to extreme cooling and vcore. I have 2 great e8400's and 4.1ghz requires 1.32, 4.2ghz requires 1.37ghz to be orthos stable. My 3rd e8400 can't get above 4.05ghz stable not matter what volts on air, and my e8400es hits a ceiling at 3.9ghz orthos stable again no matter what volts.Quote:

Such a shame, I thought my chip had real potential to get to at least 4200 on air.
I have a q807 and q813 e8500 that max out on air 100% stable at 4200mhz. Like lagunax said, 4200 for an e8400 on air isn't real common. 4000mhz is real common. I've owned exactly 2 e8500's and they both do 4200 without extreme cooling. I've also had 3 e8400's and they topped out for me and air at 4000. It seems about 200mhz is the average difference between the e8400's and e8500's. For me the extra 200mhz is worth the extra money.
e8400 q813 4.2ghz @ 1.36v air 8hrs prime stable here.

Well, its official. 445 mhz on the FSB is as high as my E8400 seems to want to go. Even at 446 it loses stability and crashes/randomly shuts down. Guess I'll have to be satisfied with a 4 Ghz overclock until I decide to buy a better chip.

wow mine went to 525 fsb without even trying hard & really havent had much time
to really play hard with it yet to see if 600 is possible getten a new nb cooler ( curtious of saaya & foxconn :)) then it's off to the races !

AMD must be giving them some real competition heh?:rolleyes:
It would be nice to get an unlocked quad for under $1000.
They are just selling old stock, to get the new CPU's in... Clock for clock your comment might be true in some cases as AMD needs to play it this way with low prices... But once you start to OC, no need to tell the story there I think... Sadly for you Extreme CPU's hardly drop in price,...Quote:

Have you tried any higher?
How much are these babies going to go for?
woot new dual cores!! :D is 50% OC on an E8600 easy to do with air or water?
Let's see what the new ones can do. That looks like a good start by cstkl1, but I'd like to see if it holds up for 5 hours, not 5 minutes.
Still, the 10x multi with the E0 stepping looks like it could be fun.
Hoping they are less sensitive to high Vcore :DQuote:

Ah, retail 8600's have arrived yet? My wife isn't going to like this. :D
Nice CPU! :up:
Mine niether me thinks :DQuote:

surfing and mucking about stable..
havent benched anything yet..
one note.. the EO temps are kindda stuck on core 1 with min 32.. but core 2 moves freely...
second.. the vtt/gtl setting of previous e8500/e8400.. now is redundant..
My wife hates computers and overclocking :)
