nope not that i can tell, had the case open everynow and then and been touching the NB and HSF base and barely even warm...... hummm
what ya reccommend i do next?
Ok I'm making progress, up a whole 15fsb so far compared to before
(3311mhz).
I spoke too soon
. I got up to 3447mhz then Orthos crashed after a couple of minutes (didn't fail, just stopped responding) both times I tried it. So I went back down 5fsb and it Orthos failed even though it was 30mins stable before, the same thing happened again after I went back another 5fsb 
. Anyone have any ideas, the config was like this:CPU: 383 x 9 = 3447 @ 1.225v
Mem: 4-5-5-15 2t @ 2.1v
Edit: Crap it just failed at stock... slightly worried!

yea thats exactly whats happenned to me
ws alrihgt at stock, did a bit of oc, was alright or a bit, then crashed, back down to stock and its still failing something is definitly up, but i think one of my ram sticks is duff as ive just rum mem test again on one stick and it failed and the other is now almomst 40% through the test and hasnt failed... so gunna try again with this stick, and the other stick on mem test to make sure, then just use the one good stick and see if tht was causing the great instability cos just after my last post and all i was doing was forum browsing and i god BSOD

I was at a similar, although not as bad, point to you yesterday. Switched everything off, went downstairs, made a cuppa and watched a bit of telly. Got fed up with daytime telly after a while and downloaded and installed the 601 bios. Cleared the cmos (got to love that switch) and left it set to clear while i re-seated all the waterblocks. Re-set the switch back to it's normal position (if you don't it creates booting problems) and booted up. Went into the bios and set the boot order etc and set the ram timing to Manual 5-5-5-15 2T and the voltage to 2.2v. Saved my settings and restarted just to make sure evrything was ok. Restarted and went back into the bios and set the Ai overclock tuner to manual, set the cpu multiplier to 9.5, set the fsb to 400, set the ram speed to 1066 (but left the FSB Strap to NB to Auto, just select the closest ram speed to 1066 in the Dram Frequency drop down), Set the CPU voltage to 1.4v, disabled Both CPU and Pci-e spread spectrums and left all other settings to AUTO on that page. You should'nt need to set any motherboard voltages for 400mhz on this board. Then went to the CPU configuration menu and disabled the following:-
C1E Support.
CPU TM Function.
Intel Speedstep tech.
I then saved my settings and rebooted at 3.8Ghz and ran Prime small fft's from 15.45 through to 11.30 this morning.
I would suggest you try the same. You never know, you may have overlooked something in the bios and resetting the cmos might clear things up. If it works it should give you 3.6Ghz and a decent starting point. Let it prime for at least 8 hours. It appears that the 8400 likes low voltages so try it at stock voltage first, just leave it at AUTO. If it does'nt boot then try 1.3v. If it still does'nt boot try 1.35v. Increase it gradually until it boots. Don't just whack it straight up to 1.45v. Have a go and get back to us later.
The cuppa helps when feeling frustrated.

Hi Midget, what is your memory? Make, model and rated speed? Come to that, what is the rest of your rig? Sorry if i have missed it.

if only i liked tea
or coffee... pah redbull will do 
mybe with vodka yea ill just let these mem tests run through then ill give that a shot with the one good stick of mem
u got msn?Are you too lazy to look for it yourself, damn these people who try to help but won't make the effort to find everything out themselves
!!! HahOnly joking ofcourse, my rig is:
Asus P5K
OCZ Platinum 2gb DDR2 6400 rev 2
E8400 - stock HSF
Right now I upped the CPU voltage to 1.25v, seems to be running stable with Orthos just now, but it's still to early to tell if it's going to fail on me.
CPU: 383 x 9 (3447mhz) @ 1.25v (in bios, CPU-Z reports 1.176v though). SpeedStep is on, not sure if I should disable it or not?
Memory: 383mhz 4-5-5-13 2t @ 2.1v
Anything else you need to know?

right well one stick is definitly duff failed within 3 seconds of memtest so calling up ocuk now to tell them... just letting the other stick go through the test again to make sure then ill try stocks again heres hoping thats all the prob was

Right now I upped the CPU voltage to 2.5v, seems to be running stable with Orthos just now, but it's still to early to tell if it's going to fail on me.

I hope you mean 1.5v and not 2.5v.
If cpu-z reports 1.176 that's a hell of a vdroop. Do you have loadline calibration enabled?The P5K is a fine board and i have seen some go to 540 fsb!! I always turn off speedstep when clocking. Should be able to tighten up your ram to 4-4-4-maybe 12 but i would leave it at 15 until you find a stable clock.
Mine has just fallen over again after 3.5 hours at 4.2ghz. Just raised the vcore a notch and trying again. This is the hardest overclock i have ever had.
Sasso. don't use msn, nor any other instant messager come to that. Have you tried moving the ram to the other slots?
well the stick that has been failing was origionally in the 3rd slot and the good one was in the first, and it failed, so been trying individually and been putting it both into the 1st slot in turn, so its ben in 2 slots and failed
I hope you mean 1.5v and not 2.5v.

Hah, I only actually meant 1.25v
. It's just ran for half an hour with Orthos so I will probably try pushing it a little bit more soon. My temps seem pretty high though: Coretemp reads 68-70c for the cores, and SpeedFan reads 60c for the CPU under load, is this too high?What does it usually mean when Orthos crashes rather than fails? Or is there really a difference, both just tell you it's unstable?

wooooohooooo finially set my settings like you have done pastymuncher but i havent upped the cpu yet just did the first bit with setting the timings DRAM volts and bios order... left everything else alone and just using the one good stick of ram (everything is a bit slower ) but atleast now im running the blend test and its been going for 10 mins now where as before it was failing in a matter of seconds.... so take that ram!!! bah!!!! im happier now but now i have to RMA the other stick hope its a fast turn over

I really don't think the temps are being read right on these cores. Mine idles at 36 degrees at stock. Now i know that can't be right. I have never had much success with speedfan so i don't use it.PC Probe reports it idling at 22 degrees but i take that with a pinch of salt as well. If Orthos fails it means it is unstable. If it crashes then it's really unstable.
Sasso, if you got your ram as a 2Gb kit you will have to send both sticks back. It actually might be quicker dealing with Crucial direct. They are pretty good with RMA's.
I have decided now that if mine is stable at 4.2 overnight then i am calling it quits and sticking with that. I really can't be bothered spending day after day running prime for a couple of hundred extra mhz. This is really hard going and for an extra 1.04ghz over stock it's not worth the hassle. I will do some tweaking to try to trim the voltages and get the timings down but that's my lot. I want to get on with some gaming.
ayyy def... the chip is going fine
woop vista is slow as hell with only 1Gb tho and yea it did come as the 2X1 Gb shick bundle.. but they each came in seperate boxes... like one in each box.... just waiting for an e-mail with my RMA instructions but seems to be taking its time ( hour and a half ) i dont think ill have to send back both sticks... or i hope not cos i need this pc for uni work 
if it doesnt say ill ring them back just to make surewell i spoke to ocuk and they said to contact crucial, spoke to crucial and they said they would only RMA it after 30days of purchase, so called back ocuk and got my RMA number and awaiting the instructional e-mail

Still priming at 4.2ghz but approaching the 3.5 hour mark now which is when it always seems to fall over. Hopefully it will keep going this time with the extra voltage tweak. Temps have actually dropped (it's getting really cold outside now), (Rad is in the window if you were wondering) and are currently at 45 degrees on each core. Tomorrow could be interesting because with the wind chill we should be below -10 degrees.
