It seems to let you adjust the PCI-E frequency independent of your FSB speed. If you are benching for a 3DMark WR it might come in handy.Quote:

thanks unclewebb
here is my chip

what voltage?Quote:

holy crap! who said Q748 were bad clockers?!!!
:slobber:
e8400 Q746a328 is a good clocker?
Mine is Q746A777 and for 4.2Ghz Orthos stable, I need 1.46V (actual).
I can boot into Windows and do Super PI @ 4.4Ghz though but it isn't stable.
It makes me feel I have a poor overclockable chip when almost all of you guys here can do 4.2Ghz at a much lower voltage. Do they pass Orthos? Just to see if mine is really that bad.
Mine - Q748A115 - clocks high as funk but it takes a LOT of volts to be stable over 4.1ghz. For benching, quick runs it's great, but I wish I had just rented it. I have another one on the way and will report differences.Quote:

On the CPU info page it also reads the minimum and maximum voltage values that I think are built into the Intel C2D processor.
Here's how my E6400 looks:

I've been running my processor air cooled at 1.48 volts, 7 days a week for a year without any of the degradation that people worry about. It would be interesting to see how this program reads the new E8x00 processors.
There's no degration going on. It's just a rumor.Quote:

It would be even better to see all batches on the same setup doing the same tests, but that may be idealistic thinking. Wait, wasn't there some thread from a guy who had like five different 8400s and was testing them on the same setup?
How do you know this? Do you have concrete evidence or is it because you just know?Quote:

The thing that stands out most is the statement that even the guy with only 1.41Vcore had his die prematurely. That sounds like bull, cuz there are people putting far more than that on this very thread, and not a single one has complained of a dead chip.
oo i might have to have a look at thatQuote:

it is stelios about which you speak!Quote:

When 1/2 cpus died and the others get degraded... i would care what he says!
Perhaps a bad series of Wolfy or real problem....

P5B Deluxe, vdroop pencil mod.
1.328v idle, 1.336v load.
pretty weird temp though. 24C roomtemp. idling at 42C and loading at 58-62C. fuzion, mcw60, pa120.2, mcp655. thats hotter than my e6600 heh :rolleyes: ill try to remount the block a few more times.

Yup I agree, those guys are not noobs!Quote:

It's right there in the spec sheet that max volts for e8000 series is 1.45v vs 1.55v for e6000 series. So people saying yeah I did so and so volts with my e6400 is irrelevant. 45nm may be more fragile. Time will tell but I hope it's not true.
Urban legends spreads fast.
It might even be that 45nm is more sturdy than older chips.
I never wrote that 8 CPU's died . They just degraded . You should read more carefuly next time !:rolleyes:Quote:

Also , 3 QX9650 (Hipro5 , Shamino , Victorwang) . You can find the posts here in XS for these CPUs. Also there is one 8400ES that died while benching (ln2) .
A new poll has been opened in thelab.gr today and already 38% voted that they noticed a degradation ... 33% doesn't tried with voltage so they don't know ... and 16% voted that the clocks are the same .
