AMD® Phenom™ II Overclocking Thread

Hey guys, manged to get 3.6Ghz @ 1.4750 pretty high Vcore? It doesn't like 1.4625 just crashes. RAMs running at 800Mhz! With the same timmings currently at 1.90 volts. Pretty stable shame I can't test without a decent cooler!
I've managed to run OCCT for around 40 seconds before the CPU gets too hot
and I manually stop it. Normally if my setup isn't stable it will error within the first few seconds up to about 20-30 seconds. I found out that the core errors on OCCT can also come from un stable RAM :S which means its not really a core error lol, turn the volts up or down a bit depending where its running at it goes away.
These 90W chips deffo need a bit more vcore to get the most out of them! Anyone else with a 90W 945? If so what OC you running?
Cheers,
Kurt

Unless you're going nuts with the voltage or letting it get really crazy hot, then there really should be no occasions of actual chip burnout due to overclocking... if it truly is duffed, yer, go for a warranty replacement. Could well have been something that would have gone fizzle even on stock speed, just taken longer to do it...
lol cheers wayne i tried most of the sites but had trouble with none of the link working, found one that works tho 
looks like quite a neat little tool to, not to sure how to use it, i just wanted to check what volatge my nb was set to and it also shows the temp of it to mine was showing 29c idle.
Need your help tho wayne with one thing if you dont mind buddy, my board seems to undervolt a lot when i set it to 1.35 stock in the bios it seems to show as 1.25 on my desktop, i want to oc to 3.6ghz but not to sure on what to set the voltage to, i tried it a 1.395 and it failed after about 3 hrs of prime

AS per my other thread, when my old AM2+ mobo died leaving my 940 without a home I decided it was time for an upgrade.
Asus 890gx board, Ripjaw 7.7.7,24 1600Mhz mem, 555BE.
Straight off unlocked very very easily at stock voltage for stock speed. The mobo auto overclocking whacked it up to 3.8Ghz without any effort at all. A slight bump to voltages and using load line calibration and 4Ghz with 1.5v was a breeze.
4Ghz quad core for £82 is a bargain if you ask me, superb chip, nice and fast, not an optimal install, had a few issues with a broken cable that came with the asus mobo and on the old install which needed safe mode, some driver removing and installing to get it to boot without safe mode properly, all seems just about fine now though.
Don't think it really needs 1.5v for 4Ghz and I can take it up to beyond 4.4Ghz in Win 7 quite easily though it got upset when I tried linX at that speed. But that was with little extra voltage. Air cooling and at the 4Ghz mark it idles at 28C(with C&Q on), and barely breaks 45C load, IFX14 with a very quiet fan on it and mostly as close to silent case fans as you can get.
I should be able to get much further with C&Q turned off and a bit more voltage, I should have headroom for temps with fan turned up. Very very impressed with the C3 stepping indeed.

Hello drunkenmaster, welcome to the thread! . . . . please read the welcome post and as much of the thread as you can! 
. . . looks like you got some great kit there!, gratz on the unlock and would be great if you can post up any stability sceenies as and when you have time! . . . . I've tried to avoid quoting as much as possible so hopefully you will find the thread a lot easier to read . . . lots of good info, screenies and even a few freebies lurking in the previous 10000+ posts!

Drunkenmaster - that is insane!
You are very lucky!
I have finally given up getting above 3.79GHz on my 555 quad. Even that takes 1.48 vcore (slightly higher in cpu-z due to 16% LLC).
I think I may retreat to 3.7 and go for a lower vcore.
Have you OCed the cpu-nb yet?

Tried getting my 550BE upto 4Ghz using just the multiplier (cpu vid-1.5v and NB 1.25v)last night but it kept crashing at 4ghz. Can get 3.9Ghz stable but cant get that exta 100mhz, using AMD overdrive and bios, do i need more volts or is this just my chips limit?

Hello all, cracking overclock of 4.0Ghz above well envious, still not find anytime to play with my setup again this week but on a brighter note I have inherritted an Opteron 146, 2 Athlon X2 4800+s, 2 P4 3.6s, and an E6600 to try and kill, when I get the time.
I know for sure I'm going to make a P4 go pop!

Ok, lol, well, despite debate a couple of pages back, the mystery tRC setting for memory is back on 40. Apparently it was fine for 12 hours of prime, but gave a high chance to fail to cold boot. Several CMOS resets later I've learned not to poke things I don't understand
Tell you what though, sitting on the floor, surrounded by the insides of your PC, the moment you discover a CMOS clear makes it beep again is... like finally getting home after a nightmare traffic jam for all two hours of which you have needed to pee. Oh, relief

If you used proper AMD memory, I imagine it'll be fine. I suspect a lot of my problems come from taking the £20 cheaper "optimised for i5" memory. Frankly, I'm happy to have them stable at 1600MHz, whatever the timings
Must be said though, I'm not happy at this growing divide. Was annoying enough when the companies parted ways on motherboard sockets, now even the RAM looks like it might specialise into incompatibility

You know, I wonder if this is because I've been using software to change voltages once I hit windows... I've got K10Stat setting my CPU-NB to 1.3v, which it needed to be prime stable with 9-9-9 memory timings...
But the motherboard is on default voltages, so at boot time... I have no clue what it will be at :S
