FX-8350 Overclocking Results

First go with all cool n quiet and turbo ect disabled. Might be too many volts as I'm hitting 63C running prime for 5 mins.

honestly why would you give a fuck? Super Pi is such a useless performance metric, it fits all in the L1D has very little benefit from complex OOO'E and is x87 for fuck sakes.

maybe pick something from this decade and that's relevant.

your 260 will be benefiting from 3 ALU's vs 2 ALU's and 3 cycle L1 vs 4 cycle over piledriver.

Its just the first thing I ran... Not really gonna bench it. It just for games, the 260 was usless for that... barely running D3 and shit

balckjok3r, see my post here regarding the uselessness of using superpi (and many other derivates of the base code algorithm) on an AMD cpu http://forums.overclockers.com.au/sh...2&postcount=85

using it to compare times between different architectures doesn't really tell you much of its own accord ;-)

Lots knock SuperPi cos AMD sux;s at it ...

Even the cheapest intel chip runs pi hard

Its still relevant though for comparing AMD to AMD eve if the score's are embarrassingly high .....

no it isn't, its usefull for comparing SKU's within a Uarch.

Having heaps of trouble getting anything to boot or work. Cant get over 4200mhz... using multies or base clock. No amount of voltage seems to help.

Its just weird. Might be this board as with the 260 I needed to use onyl the 1600 memory divider and huge base clocks to acheive stability. I really cant be fucked screwing around doing that again as it took weeks.

This chip sitting on 4200mhz with ram 9-9-9-20-1T 1866 and NB at 2400Mhz seems to work great. I also cannot boot with NB over 2400mhz, wont even post, no amount of voltage is helping that either.

I've tried up to 1.475v with 4600mhz and got to windows. As soon as I loaded prime 95 it froze then BSOD. I give up.

reset the ram freq's and timings first of all. Very little reason to do it in the first place, especially if it's holding back your CPU/NB freq's.

I had an Extreme 4 and it sucked hard. ny sort of overclock would cause the lan port to stop working and various other instabilities. Stock settings and it was rock solid. I upgraded to a Crosshair V Formula and run 4.5ghz at 1.28V on my 8120. The extreme 4 is a terrible board.

[balckjok3r]

Yeah I'm starting to think so... I wish people knew that when I fucking brought it, but all reviews said it was perfectly fine. Guess its the same as reviews for D3 saying it was a very polished and finished game when it came out. because they only played normal and didn't know any better.

i have an asrock 890gx extreme3 with similar issues, try upping your southbridge voltage a little, and stick an old 20mm fan on the heatsics...

[balckjok3r]

I think the problem is the drop on voltage... It will go from 1.44v to 1.38v as soon as prime starts and then lock up. I think there is a setting in BIOS called LLC or something, which can be set to 0% and actually give a voltage rise under load. I'll have a look into that this arvo.

Also I will drop ram to 1333 for now as I think over 940+ 9-9-9 is a bit quick and might be causing problems. I need to set my voltages off auto, although nearly everytime I touch them all at once it dosnt boot so I need to do them one at a time.

Time to overclock the CPU-NB

Set everything to default !
Dont push the ram timings , on some combinations it can cause problems .
[ Lets concentrate on one thing at a time ] = CPU

With everything stock ..
Just increase the multiplier , and keep an eye on temps ..
play with the cpu voltage a little .. and let us know how it goes ..

If you're a just testing to see how far tis chip will go this is where I'd start, by the sounds of things you're trying to achieve too much at once. if you know what you're doing I'd ignor the below.

This is how I overclock on a new arcitecture:

Set everything to default and turn of ALL powersaving features.

I'd then set LLC to full/high, Vcore to 1.35v (low enough that temps arent a problem), a small bump in CPU-nb voltage, and just see how high the multiplier can go, test for stability.

Then set your multiplier to stock(ish) and see how high your FSB can go.

Once you have a rough idea of how high you're chip can go try and find your 24/7 overclock, get the FSB as high as you can with out taking a huge cut in frequency. THEN, you know what your chip can comfortably do so ocing NB/Memory and enable powersaving wont leave you wondering about where stability is lost.
