Try post a screen with that speed and a 5*intelburn test session, then we can compare. I did first get the chip yesterday, so just started testing.
Atm i will let run at around 4400 mhz with low voltage, because the only thing i use my computer to is gaming WOW and a litlle fallout 3, and both games run so smooth i can't feel any difference.
It's not logic, you have to admit that, you are able to cool a CPU below ambient temps with non chilled water...also your load temps are amasingly low... your sensors are for sure borked at idle, probably too under load... Tjcasemax selected is 95, I would set it at 100 or 105 for more realistic values...Quote:

every thing you said was debunked from the start...because True Temp reads 27c idle on the same board and cpu and dosnt go over 49c on 100% 30 min prime 95...so like i said its Real Temp that,s reading the wrong temps...i said true temp reads 22c idle and i got a reaction....people wanted screen shots so i gave them...i never said i believe themQuote:

nothing stresses my chip like youtube and xtremesystems. A true stress test. Intel should learn from the best
:shrug: your new values are more believable and even 32°C idle is still perfect... be realistic if you tell us you got 77° ambient, it's hard to idle at a lower value not ?Quote:

Look for anything after Q821XXX and you will be fine... E8600 is for sure EO ; most E8500's too , but with 8400 you need to be carefullQuote:

looks like I will be in this thread a lot now. I just picked up a CO stepping e8400 for $120 at microcenter. I got tired of the insane volts my current chip takes. I can't wait!!!
How are your temps the same on load and idle?Quote:

could be because of how low i set my v-core in the test keeping the heat down its also water cooled thats the only thing i can think of....when its at 4.45.ghz 1.344v..it jumps up to 49c on prime 95....but for the screen shots above i wanted to see low i could set the v-core at its rated speed of 3ghz which was 0.992v and it passed an hour and a 1/2 of primeQuote:

List your system, CPU/Mobo/RAM etc. in your sig. It'll help everyone to know what you're running on.
I'd start by setting your RAM to cas 5 and seeing how well your board responds to NB voltage increases. It does look like you'll be in the 4Ghz 1.3vcore (+/-) crowd, though. It's good company for C0's.
Finally, i find pretty good E8400 after several bad tries. It's Q830B153 Batch with VID 1.1875V. It's working Ortos stable with 450x9 (4050mHz) only on 1.15V, 4.2gHz with Auto 1.18V. Tried also 4.5gHz, but it's need some more voltage. Pushed to 1.34V and stop the Ortos after 2 hours successfully running. Needed also increase CPU VTT to 1.26V and PLL to 1.64V. All that with air cooling Zerotherm Zen120. With good liquid cooling the CPU can be pushed to 5gHz, i hope..
I've got a bad E8400 E0 Q832A378. One of the cores always craps out while the other stays stable. I need 1.34v just to keep both cores running @ 4.05GHz. One core will keep running in P95 @ 4.27GHz with 1.29v while the other errors out. I need 1.43v to keep them both stable. That's terrible compared to other E0 chips.
Ummm, didn't anyone else catch this? I really don't think that is the case.......can anyone say "new world record" LOLQuote:
Edit: also what is the limit for my memory anyway? Its OCZ Reaper HPC 2x1GB DDR2 8500 .. Right now its running at 2.1V, 1770Mhz, fully stable and passes memtest. How much can I go with this memory?
If your picking up E8400 you need to talk the saleman to look forQuote:

and the Batch#Q820A832 atlease look for batch in the 820's
Best of Luck:up:
Finished the system in sig a week ago, still tweaking it. So far, I'm noticing this CPU seems to want higher voltages than most EO's. Batch is Q832A161. Got it from neweggs NJ warehouse btw. Can get a 4.5G overclock, but it takes 1.4 vcore and running the FSB up around 500 makes my RAM wonky. Cranked the FSB down a bit to try some tighter timings on the RAM, but noticing the vcore needs to stay a bit high. Right now I'm running 450MHz Bus, x9 multy @ 4.05GHz...which wants a vcore of 1.36. I can pass an hour of OCCT at these settings.
ok. .will try your suggestion and increase the NB voltage a bit. I am trying to make at least 4.0ghz (so a 445x9). Should I increase the CPU volt a bit as well?Quote:

strange, but a couple of days ago my computer became completely unstable after 2 months of running super stable....random restarts often, and a couple of restarts that would end up in non-reboots; had to turn PSU off, and start over.
I bumped Vcore from 1.28750 to 1.29325 and a little better but still rebooted. Then up to 1.3000v, and almost good but had two more reboots. Up to 1.3250 and now it is stable again! I didn't want to run that high of a Vcore, so I went back to FSB = 430 (3.89ghz), and put the Vcore down to 1.2835 and now it is running perfectly fine.
my board is a Asus P5Q-E, see my sig for more details
Yeah same here, though I have a feeling I never had enough NB voltage to begin with (only 1.34v in Windows since February 2008). I also, however, never played a 3D game long enough to really stress test. I played TF2 max maybe 1-2 hours at a time. L4D has me playing 4hrs+ per session, and pulled some Windows file BSODs (which I consider not as serious as the typical IRQ_LESS_THAN_EQUAL ones). A few bumps in my NB voltage, and no more BSODs. But I can't help but wonder if my 2hour OCCT checks are simply not enough (compared to 3D stable).
Hell I could probably drop my vcore back to 1.296vcore, but I'll probably play it safe like an old man and leave it be. Load temps are what, 1C higher b/c of a 2-step bump in BIOS. No biggie.
*actually you know what? Maybe we did experience degradation, and we :banana::banana::banana::banana:ing babied our procs with only 1.3vcore. :|
