4.5GHz is doable on just about every cooler with the right settings. The board is very capable of overclocking, the CPU varies but a lot can get to 5GHz. Have you just kept everything at stock and increased the multiplier? I'd first try to see how high you can go on stock volts, though you'll want to change the LLC setting.

Hi Schizoid, a new addition to the forum - only three posts! Damn voyeurs these days!
If you have some reasonable cooling then as teppic has said 4.5+ is the possibility, plenty of help here and more info accumulating all the time.

YOu can benchmark till the cows come home but most rigs wont be pushed under that strain ever.
Either game for a couple of hours and monitor the temps or run some of the tests mentioned in this thread.
I personally fold overnight on a medium setting, then gradually increase till it's full. If the system was unstable it would either crash, hang or reboot.
Sometimes systems can pass a test yet crash in gameplay which is where you dont want it to happen.

Took mine down to 4.4ghz on 1.3v for now 
it's lowered my temps by 20c so I'm hitting 52c in LinX (which makes it hotter than any other stability test I've tried).
It's getting to the point where the lovely lady and I are putting the heating on, which is adding at least 10c to the ambient room temps. It added a second onto each pass in LinX so it was around ten seconds slower. Still bloody good though
Until recently I would have agreed with you 100% mate. However, I can tell you here and now that Crysis 3 has a couple of levels that actually put more strain on my CPU than Prime 95 :O
There were only two, but, on either with my old rig (990 FX Extreme 3 and H60) my CPU was throttling to 1.7ghz to cool itself down. One of the levels is basically a load of wrecked buildings in a swamp sort of thing, and the other is the one where you have the buggy and drive around the massive expanse of wasteland.
I've got a little video screen temp monitor and my CPU was hitting 100% load :O madness !

If you can see similar performance with low temps then that sounds good!
By the looks of it most cores will go 5Ghz but insane cooling is required. I think I would be happy with 4.5Ghz for day to day use.

Not getting too carried away just yet I haven't even got the components!

Asus Sabertooth 990FX R2.0
Is this the same thing or is there an Evo special or something?
Theres a sabertooth rev 1, which has greenish heatsinks
a sabertooth rev 2 which has browny heatsinks
and finally a sabertooth GEN3/REV2 with PCIE 3.0 and a few heatsink improvements. This board is actually not stocked by many retailers for some reason and does not appear to offer any worthwhile benefits over the older rev 2 imo

Played about with the CHVFZ and the 8320. I left the settings completely untouched except I set the multiplier to achieve 4.6GHz. I also enabled offset +ve but left the offset voltage to "auto" and put LLC to high.
The system is automatically sticking to 1.35-1.365V at load and dropping nicely to under 1.1V with clocks down to 1.7GHz at idle. I'm really happy with this board and chip. They easily perform similarly to my previous 2500k clocked at 4.9GHz and seem very solid. I think I could start underclocking it by setting some negative offsets when I have some time.
By contrast, the UD3 was at 1.38V at idle rising to 1.4V at load when totally stock and all features on default in bios. I also needed around 1.4V to achieve 4.5 GHz on that board so it needed a bit more juice. The throttling was also a major issue which has now disappeared on the ROG board.

Glad to hear you're happy. I'm thrilled with mine tbh. I guess you have to have one and actually see for yourself how good they are.
I've been playing the voltage game today too
trying lower and lower each time now

Thanks Andy. Where have you got to voltage-wise?

Sounds like the board is shining through then, are you getting higher speed on less voltage with more potential?
You will every time on a better board tbh. The power stages don't just help with huge balls to the wall clocks, but will be a lot more stable at delivering stable power with lower volts too.
I certainly won't make the mistake of buying a cheap board again. It's really cool that for £160 you can get such a thoroughbred
1.37 for 4.4ghz IIRC. That's LinX stable which seems to be much harsher and quicker to find out if the chip is stable

Yes Thont as Andy says, the ROG board is achieving higher clocks at lower voltages. My main mistake was I only checked the OCUK website when looking for FX 8320/8350 boards and at £190+ it just seemed too steep for a second system which my son would mainly use. The price of £160ish though makes it much more worth it. Asus use the same/similar heatsinks/caps/materials on all their ROG boards and you can certainly see it on the CHVFZ.
Andy great going there. I'm the same, I prefer LinX or IBT as it gives a really good idea of stability much faster than hourse of prime. Both have their place but ultimately gaming/folding for hours on end is where its at in terms of stability.
