Thats not a 24/7 speed. Im running at 4.1ghz 1.55v 24/7.
That was more of a hey lets see just how high it will go devil.gif

I was able to boot 4.4 at that voltage but couldnt get it to validate before crashing:(

Although I think if I did some northbridge tweaking and took out my crappy corsair ram and just ran my gskill i could probablly get it to run close to 4.5

Hi Athlon II X3 Owners!

I need help with my OC. As you can see in my sig, I have a crappy MSI board.
And from what people in OCN told me, I should choose my max vCore with care since my MoBo is not heatsinked. So I limited my max vCore to 1.432v (based from CPUz).

So this is what I get:

X3 OC
CPU-zA2X3440375GHz1432v.jpg

X4 (unlocked) OC
CPU-zPh2X4B40338GHz1432v.jpg

Help me choose which is better. I mostly do gaming: LoL, SC2, Civ5; also normal web stuff and office stuff. I'm also looking into AutoCAD and WinGRASS (GIS).

And lastly, is it fine to increase my "safe" max vCore to 1.45v or higher for the X3 since it has lower TDP compared to the unlocked?

I appreciate any comment or suggestion.
Thanks! smile.gif

No, don't raise the voltage more. Nobody can know when the mobo will say "poof", so don't risk smile.gif
The quad will be faster, but will also be more dangerous to the mobo, because of what you said about the TDP smile.gif It's not just the voltage, it's the TDP that burns the VRM unit.

Ok, so it will be just fine as it is (with max Vcore of 1.432v).
So I will stick to quad OCd rather than tri OCd?

xd recommended tri OCd, but didn't mention why.
Any ideas? Or maybe because its safer. Hehe..

Thanks! smile.gif

Because of the TDP. Any OC or unlock threatens to blow your VRMs wide open smile.gif And you have both OC and unlock. The limited voltage itself is not much of a safety measure, ppl have lost their MSI mobos with stock CPUs, stock voltage, no unlock...
So actually nobody can tell you at which point your VRM will blow, but certain things are more risky than others. The higher TDP just puts more load on the VRM.

And about performance:

Athlon II x3 @4.2 pulls 40GFlops
Athlon II x4 @3.3 pulls 40 too

You're choosing between x3 @3.75 (~36Gflops) and x4 @3.4 (~41Gflops) smile.gif

GFLOP/s don't mean much at all when it comes to PC processors.

It depends on the games you play and apps you use. Look up benchmarks and find out if they favor higher clock speeds or more cores, and go with whatever seems best. Most of the games I play don't take advantage of 4 cores, so I dropped in my Phenom x3 and it gets the same/slightly better performance in almost every game I play, while being cooler and requiring less power.

Gflops mean EVERYTHING about CPUs.

Maybe if all you do on your PC is play 3 year old games, then yes.
But all new titles will be optimized for quads.
Also lots of people use their PC as something more than gaming consoles smile.gif

No, GFLOP/s mean very little. Integer operations are a much better way of measuring PC CPU performance, floating point operations are handled by the GPU in most cases (hence why video cards are breaking the 2-3 TFLOP/s mark while CPUs are still struggling to break 100 GFLOP/s in most cases).

New Vegas, L4D2, SC2, Borderlands, Dirt 3 etc., all perform better on my 3.2GHz tri-core Phenom than on my 3.5GHz quad Athlon.

If he's interested in some games coming out that use quad cores better, he can just swap over to his quad core settings. He isn't asking what's better in the future, he's asking what's better for him now. What's better for him now, is to look up whether the games and apps he uses right now take advantage of cores or clock speeds more, and adjust accordingly.

And I know that people use computers for more than gaming, that's why I said:

and apps you use.

but regardless, he said:

I mostly do gaming [...] also normal web stuff and office stuff.
