Hi! I've been working on this CPU for a while and I've managed to get a stable overclock of 3677MHZ. Not very impressive, but also not totally worthless
Its stable @ 65C on air. What is just acceptable, since these are known to run very hot. I could push this to 3700, maybe even 3800MHZ but then the temps will get to high. If i had this CPU on water i would have no problem getting it over 4Ghz. I would have to get a different PSU, since this is a 550W B-brand.
I had to push the Vcore up high in the bios to get this stable;
Lapped D830 @ 3677, (22% Overclock)
1.4200 @ bios, Actual reading in Windows is 0,1 Lower.
5-5-5-15, 1:1 Ratio
It seems that to get A D8xx series stable you need to push the Vcore Up high, so dont be afraid to crank that Voltage up when you have a decent cooler when you are having issues with stability.
They run Hot. So get a good air cooler, or if you want to go over 3700-3800MHZ get water, or a one step higher cooler like a V-8. But its better to straight go for water if you want to get these speeds. But since this is a old cow, its probably a better idea to save that money up and buy a Quad, or Six-core CPU
. But i just like Overclocking.
