E8400/E8500 overclocking thread! - Page 10

E8600 is E0. For E8400/E8500, not yet, at least I haven't seen any so far.

From what I observe, E0 is about ~200MHz better than C0 on average when it comes to overclocking. The upcoming revision E0 E8400 might not overclock as good, most better chips will be going to E8600.

You can check Asus or Gigabyte's cpu compatilibty list or Intel's cpu list. E0 Stepping exists for E8400, E8500 and E8600. Every board I've seen requires a bios update from it's initial bios for these E0 cpus.

I'm looking to try 9x400=3600GHz and later 9x450=4.05GHz with with the least possible stable voltage. Course I'll be running at stock speed until my hyper212 arrives, I'm not going to OC on stock cooler

...

No clearance issues with the Reaper ram here use slots 2 and 4

Actually the P5K Premium board was eating my reapers.

Now on 2 2gb sticks so we'll see....

D9s on my older reapers seem to die a lot anyways. New sticks run lower voltage too (Andy @ OCZ was a big help with my reapers but he did say the sweet spot for voltage was ~2.2v for my old reapers with looser timings of 5-5-5-18 - but new set is running ~2.1v with those timings - wonder what chips they are using).

And there is an upcoming E0 for the E8400. Mine isn't though.

Which style of heatspreader are on the 2 x 2G you are using? I know you had some issues with the 1 x 1G sticks on that mobo hope its sorted for ya

Well finished installing and had to use the stock intel E8400 cooler for now (gulp). That is not an experience I'd like to repeat. Realtemp shows idle temp of 38c yukh. For my 5000+ Black Edition (also a 65w cpu) @ 3.1Ghz idled at 26-28c with a zalman 9500. Anyway it seems I have a VID of 1.2250 which is not as good as I had hoped. I'll be back to post some screenies.

strange unix
but that is not that much high by 0.1v higher than my

I idle at 22-24C on my E6550@3.1G and I think my idle temps were lower than yours using the stock cooler

It didn't work half bad just soooooo noisy

Anyway I will send an email off to Coolermaster for you in the Morrow

Just wait till I get my hyper 212

...
Well as you already know core temp sensors are not designed for measuring idle temps and hardly ever accurately do, they're just designed to to trigger throttling reliably. To make matters worse nobody knows the real tjmax, and intel doesn't release them. I feel I can trust realtemp.

Anyway considering the ambient temp is quite higher than 22c and it's a stock celeron cooler with stock paste at best I really shouldn't be complaining about idle temps. It's half the size of a 65nm core2 cooler with a aluminum base, no copper and no heatsinks and three strips of god knows what preapplied tim.

Hmmm it seems I idle at 38c core (34c cpu) whether speedstep is enabled (2GHz + lowered voltage) or disable (default 3GHz). Asus fan control is disabled... /scratches head
Full loads creep up to around 48c but fall back to 38c pretty quickly once load is removed. Maybe if I used arctic cooling mx2 instead of the stock paste I'd be able to get that down. My idle temps are exactly the same as some E4500s (2.2GHz) with speedstep enabled running with the stock coolers in the same ambient environment in less ventilated cases.

that temps are strange unix
