The Phenom II List of Overclocks

Might be very good one. What is the cooling and the ambient temps.

Noctua NH-U12P + 1 120mm fan (12v). Ambient is about 15°C.



I'm not really getting the NB freq as high as I hoped; atm stuck at around 2400MHz. Maybe I need a bios update to get it working better.

My NB is stuck also like yours to around 2.4GHz. What is the difference in percentage between 2.4 and 3 for example?

The difference in efficiency for 1M will be around 1500 maybe (2.4 - 70500 // 3.0 - 69000), which is very little in real-life. However, it's always cool to show off 3G NB clocks ...

Got it. I don't care about the NB from now on. I really prefer stability to some 0.2-0.5% performance increase.

I have the same 0850BPEW chip. Mine is easy on NB clocking. Just needs around 1.3V for 2.7GHz. Problem is that my mobo doesn't have option in BIOS to increase it, so I'm stuck to 12x multi at max. and then HTT clocking in Windows

BTW I will try to show 4.275GHz Pi 1M time on AIR soon. I did one but comp hang up while opening Paint

Use MVSNAP instead.

you can setup screen capture with a hotkey to save desktop as jpeg......no need to use paint and it's done in a fraction of a second so most usually will complete before an unstable clock has time to fail

It may add 0.171secs to your Pi times but that just means you need to OC higher

Thanks for a good tip
I was looking for something like that!

I'm after this one: Lastviking's 1M AIR record

I've beat it on my lunch break once so there is a hope
BTW his result is truly excellent!! Congratz Lastviking

This seems to be the max 24/7 setting for my X4 920 (it will go higher, but too much VCore for my liking).

MSI DKA790GX
X4 920 - CACVC AC 0849BPDW - ***80024
2x1GB Geil DDR2-800

VCore=1.475 (Bios)

Wow, that's not bad! Mine seems to give up at around 2.5GHz (booting, blue screen when opening windows) ... I'll try to update the bios (if possible) and see whether I can improve my clocks.

Furthermore, I'll try to catch your 1M on air tonight, again if I find the time. I need to pick up some LN2 for tomorrow ...
