my e8500 was 1.225vid but did 4.32ghz stable. My E3110 is 1.225vid but does 4.23ghz stable
.....aint too bad.

4ghz should be pretty much guaranteed tbh.

Won't be for a while yet, I'd guess we won't see the lower end E0's til end Oct/Nov time, first ones we see will prolly all be speed binned E8600's as well i'd guess.
So might be longer before we get good clocking ones. Suppose we'll have to wait and see.

My Asus P5KC wouldn't stabilize with fsb raised more than 7 so that is being RMA'd .. I'm sure it had something to do with the high pitched noise coming from it.

E8400 still worth it over something like a Q6600? With these overclocks its tempting to get one, will it boost fps in some games that would be CPU limited over my E6600 @ 3.4Ghz?

OK people. Answers on a postcard to this one please:
Been trying to get 500 x 8.5 stable for the last couple of days with no luck.
I can Small FFT / Blend / Gromacs all day long at 490 x 8.5.
I can Small FFT / Gromacs all day long at 500 x 8.
But Blend always fails at some point within an hour, it might be 8mins it might be 50mins, but it will always error.
Now I know my mem is good for 1000Mhz (that's its stock speed for a start), I know the CPU is good for 4.25Ghz (tested on lower fsb).
I have tried with NB volts at everything from 1.45-1.6V and it is the same, and i've tried VTT from 1.15 - 1.4V.
How can 490 be solid, and yet anything over that on 8.5 will fail Blend.
Soooooo annoying, I will have 500 x 8.5 dammit

Have a look at the link in my sig. Although we ar'nt running the same mobo, a lot of the settings in my rig might apply to yours. One thing to keep in mind when you are at the 500+ fsb level is the buffer strengths and slew rates, ALL 45nm cpu's prefer thaes set to strong, it makes a huge difference in stability.

Is 3.8Ghz at 1.28V ok?
I'm currently stressing it with Orthos, its showing as 1.28V in CPU-Z if thats accurate?, done 10mins so far so doing good, gonna stress it for an hour then push higher.

so small fft's will only check your cpu for stability is that right
Yes, Blend for CPU & RAM.

cheers jimAroo,i have always checked the cpu and ram together never done the cpu on its own

Just got a new Xeon shipped over from the states 
Older stepping Q745A784 and seems to be my best clocking wolfy yet! Temps seem awkward but they are still perfectly reasonable, perhaps the IHS is shaped oddly.

hi guys , built my first machine capable of overclocking, moved from an AMD64 3200 agp system with ddr ram to the below.
Asus PQ5 deluxe
E8400 cpu
artic freezer 7pro
ocz ddr2 6400 gold
antec 300 , with 3 additional hiper fans
4870 ati graphics
thanks to all your posts i found setting up and overclocking very straight forward.
is there anything I have done fundementally wrong.
Thanks Bowza

make sure your memory voltages and timings are set correctly

Been waiting before I tried o'clocking my 8400 - CO revision.(Tuniq Tower Air Cooling, fan at mid - i.e. quiet setting)
Running on Asus P5K Premium - with 4gb Corsair DDR2 XMS2
VID : 1.1875
Temps at 3ghz per real temp = 25c@Idle 38c@load Volts per Cpu-z (auto in bios) 0.984-1.152 max
Did enjoy the simplest overclock I've ever attempted i.e. Set fsb to 400 cpu voltage in bios to 1.165 & Ram as DDR2 1066 - everything else left at auto. Booted and ... it flies 
Ran Orthos for 15 min - no errors .Will run it for 1hr + at weekend to be sure but I'm already convinced that it'll be fine !
Temps per Real Temp as I type this 25c/28c. Under Orthos 39c for both cores (have noticed that my core temps do equalise after a few seconds under load)
Volts - Cpu-z says 1.120 when under load & 1.136 at idle - I found both these somewhat confusing as I did set Bios @ 1.165 .
I believe the general lower reading may be vdrop/vdroop ? is it at all worth worrying about ??
Overall I believe I've got a good chip - Am I right ?
Will be aiming for 4ghz in time - want to give this o'clock time to settle , and to know with certainty it's o'k ,before trying.
20% o'clock - much better than the Opty 185 I used to run out of which I could only get 7.5%
