**Official e8400/e8500 Retail OC Thread

[GLENBOY]

hiya thatguy its still going now whilst i'm typing, now 38 mins now, its weird i had an e8500 and that required low volts but ran hot, and this one is a little hot in my opinion considering its only 1.272 vcore whereas the q750 i had ran cool but required more volts , on a side note i think your more than safe with your ram volts

[Chri$ch]

E8200 (Q745A705) @ 4.2Ghz (1.288v VCore)

[WiTcHkInG]

had a q750a e8400 and it needed 1.43 volts real to be orthos stable changed it for this q745a533 and this one is orthos stable so far at 1.272 volts, at 4050mhz

The Q750A seem the poorest batch so far. Cant get any stability at 4Ghz with upto 1.45v.
Got a Q746A coming hopefully tomorrow so i hope i get better luck with that

[GLENBOY]

yes i think best batches are q743,745,746 the q750 i had was cool running but needed more voltage than everybody elses to be stable anyway

thats what you call bang for the buck

E8200 (Q745A705) @ 4.2Ghz (1.288v VCore)

It's really good for e8200

[ixtapalapaquetl]

Ya, sorry i meant can you take a picture of the IHS and CPU afterward.

I kind of don't want to mess with removing my HS unless absolutely necessary seeing as how things are in a delicate way right now. I will snap some picks when I pull it apart next week. In the mean time, it looks very much like this http://en.expreview.com/?p=142, except without the crud on the CPU.

Nice vcore for 4050mhz Glen im glad you found yourself a good one m8

Sweet chip. Mine is doing similar but only prime stable tested at 9x multi <1.28vcore.

I'm about to switch to 8x and explore top stable clock under 1.3vcore.

Mind if I ask your other voltages - NB/VTT? How about gtl settings for that clock?

NB @ 1.55v
FSB @ 1.20v
NB / CPU GTL @ auto

[Achill3uS]

Q746A513 E8200s are nothing special... like my Q744A761 E8400 was, 4G @ ~1.36v



max fsb on p5k3 deluxe

i hope my Q746A512 E8400 will better... i will got it in a few days...

NB @ 1.55v

Is it stable large fft's ? at 525 fsb

they are weird the maximus they don't seem to like high fsb at max clocks i have tried 2 e8400 and an e8500 and they seem to flake out at 510 fsb

[Zucker2k]

they are weird the maximus they don't seem to like high fsb at max clocks i have tried 2 e8400 and an e8500 and they seem to flake out at 510 fsb

I get 9x544.9 fsb on my maximus with my 8400, should do more at lower ratio.

Heres a super pi run at 4.3 @ 1.38v (in bios). I think it still needed another small voltage bump, i was getting a few "this program is not responding"

Seems like it wants some vcore anything past 4.1

[Infa]

these X38 are like needles in a silo

some are crap some are good, dunno why, my sucks..

Got it stable at 4,3 now 1.45v, think 2hrs are enough..
4Ghz it will do at 1.25~ will repost more accuratly later.

[Zucker2k]

If you want my opinion, DDR3 is so NOT WORTH IT!

[Infa]

have you played with ddr3? i got sloppy timings couse in non benching, i dont need to lower it...
and please do not try to tell me what's worth to me or not, my descission when i bought it.... and im happy with it... clocks well and benches better than ddr2.. so so tired of all people just complaining of the damn ddr3, JUST DONT BUY YOURSELF IT THEN, and those who want to can do it.......so you think all you stuff are nescessery? cmon , cut the crap, this is XS and no whining booth. let peps get what they want! and enjoy their results!

[GLENBOY]

yes its weird i have tried 3 new e series cpus and they all seem to go to 4600 but no more some with lower voltage but after 510fsb they get unstable no matter what volts on nb or cpu

which bios on your DK P35?

Try the last, with it it show the right vid.

Tested C24 bios as sugested

EIST enabled VID 1.1125 vcore idle 1.15, vcore load 1.20 (cpu-z)
EIST disabled VID 1.0500 vcore idle 1.13-1.15, vcore load 1.13

Dude, that was a general statement. Not particularly directed at you. Anyway, enjoy!

I thought core temps aren't tied into BIOS? Just frakin' inaccurate sensors. I suppose 28C's is more realistic anyway, seeing as I'm only on air. Not sure if it was this thread, but someone was using cascade (spelling?) and said that his core wouldn't even detect temperatures below 27C's - it just stopped there.

they are
all sensors readings goes trough the I/O.

[FlyBoyGeo]

I had a X38 asus Maximus formula but sold it as it was a piece of crap to overclock, about 1 week before i bought my E8400. So no i haven't tested it on a X38. I will be testing it on a EVGA 780i on friday.

Did you ever test it on that evga mb? How did you do?

There are some Q750 batches that are good.
Q748 surely sucks. Q746 is best so far at 80&#37;.
Q745 and earlier seems to be the best of all
