I just think that that's weird how you have to pump up the vcore that much when I can get my 5000 BE to 3.22 by just upping it to 1.4 which shows up as 1.42

Increasing your northbridge voltage a little might let you bring that vcore down a bit.

While our systems are not exactly comparable, I think they are similar enough.

My idle temps are about 32C (21c ambient right now) with 1.3v to the core. Full load is about 46c with the same ambient.

When the ambient goes up the idle and load go up in a direct relationship (1:1).

This is a 900mhz OC on a 3600+ Brisbane.

When I push the voltage closer to 1.4 my temps reach about 55-58 under load with an ambient of 23c. And unlike you it doesn't seem to help my OC. I haven't tested at higher vcore/OC since the ambient temps dropped.

edit:
I support what alwaysAMD said. When I upped my NB volts it allowed me to drop my vcore from 1.35-1.375 down to 1.3. That lowered temps considerably.

How ironic, firefox crashed just 30 seconds after posting that, and attempts to reply eventually just crashed my cpu

Dobbie, I think the most likely factors are one of the following:
1) the Black edition cpu's are better oc'ers I believe, and this probably plays a role
2) I got a cpu from a bad batch//you got a cpu from a good batch or both

Ahh thanks alwaysAMD, solid advice and its already helped someone out sadly however I'm already maxed, like most Asus mobos I've worked with, there's not a lot of room for voltage increases. While thats a bit sad, at least it means my mb varies from 33 to 37 degrees going from default to max

Glad to hear anticrainbo! Lowering temps is always a good thing, and a 900mhz OC for an amd chip is impressive Our ambient temps are roughly the same, so its always good to hear a similar comparison.

Like you, raising my vcore past a certain point provides diminishing returns, very quickly reaching a point in which adding more voltage will not help at all. I'm guessing this is the when the cpu hits the wall, or its a bios error. For me this seems to be @ around 1.47v (for a 3.12ghz clock) and while upping it to 1.5v allows me to run @ 3.15ghz comfortably (testing it right now!)

Upping my vcore to 1.6 which is a whopping .1v increase does not seem to help me regain stability, so I have to assume its either my cpu (most likely the case) or my bios (either some setting I'm unaware of, or the revision version). I was hoping it was the latter, since playing around with the clock skews I can get my system to constantly boot into windows and run orthos for a short period of time (anywhere from 10 mins to ~2hours) all under the same settings; it may crash instantly under one clock skew combination, while lasting 2 hours under another. Or so it seems, could be coincidence *shrug*

So far I can almost certainly rule out my memory, but there may be some setting I havn't played with yet (adjusted all the major timings however), and my mobo since it can sit stable at an fsb of 280 + while having a picnic.

I think I'm just going to sit @ 3.15ghz w/ vcore @ 1.5v, with my memory @ ~1080 5-5-5-15. Full load temps would avg prob avg around 60-65 once I adjust my cooling a bit. Its a bit of a shame because its .05ghz off the goal I had hoped for, but at the end of the day its decent enough ^^.

Hopefully its not my cpu, and when I get some spare time (finals are coming up soon) to play with some settings, I can hit 3.2ghz! or perhaps if asus releases a bios with a miracle fix that'll work too

Anyway thanks guys If I manage to get any breakthroughs I'll report in here, and hopefully be able to help out in some other posts. Good luck with your oc's!

Try this. 320x10, HT 3x, 1.45v vcore, Drop the memory divider to DDR667,loosen all your memory timings, and try to boot. Some boards just like a higher fsb and can be fussy.

ahhhh I was thinking it was time to sleep, but I cant resist the temptation to give it a go Many cheers, and I'll give it one last shot before heading to bed. Thanks once again!

new to OC:N, had to bring up the user cp to see how I ended up with 1 rep. thanks for the rep anticrainbo!
