**LETS SEE YOUR PILEDRIVER OVERCLOCKS - LET ME START WITH 5GHz+!!**

The custom PC benchmark is very old, single threaded.
Not so good on modern hardware.

PD does ok on the x264 bench.
Hits the CPU hard though so if your not stable it wont finish.

Handbrake encoding tests could be used.
However that now uses AVX and the Intels have picked up a lot of extra speed.
PD wouldn't look good being beaten by the i5's.

probably get beaten by trinity if you included open cl too
 
Hi there


Here is some Heaven results at 5.25GHz though the OC does very little in Heaven in 1080p as it due to the graphics, but the Piledriver chip is certainly no bottleneck:-


Heaven @ 1920x1080 w/ 4x/4x and tesselation on normal!

Heaven @ 1680x1050 w/ 4x/4x and tesselation on normal!

Also the 7970GHz cards are insanely fast, this is an Asus Matrix Platinum at 1270MHz core and 7100MHz memory, wow what an amazing card!! :D :D :D

Got cinebench to run at 4.8 but x264 will not due to heat, need better cooling, will attach x264 at 4.6 shortly

Raw results from x264 run at 4.6GHz

Please do NOT compare it with older versions of the benchmark!

A Gigabyte 990FX UD7 and its Vdroop is absolutely terrible, Asus are bringing me a board tomorrow, shall see if that is any better.

If anyone knows a quick easy to run benchmark that is more fairer than the out-dated SuperPI let me know and I shall run it for you. :)

More fairer? Good Ingerish :p

Looks a bit low that. This is an older one of mine before I finished tweaking RAM, I get 8.31pts now;

Edit; also it's worth noting that my 8320 isn't a great clocker by all accounts, needing 1.53v and ultra llc for stability at 4.8ghz.

Is the FX-8350 any better, or same?

I have not achieved prime stability at 4.8 however I have not gone above 1.4375V yet. I was able to boot into windows at 4.8 and run Cinebench with CPU-Z and HW monitor active. Prime failed on two cores within a minute but seemed to run on on six until I turned it off.

4.6GHz is good and remains within spec at 1.4V. Core temps at 55C on prime and fans are fairly quiet.

I need to sort out better cooling to increase the voltage which may be this weekend. Undecided whether to go for a newer case or just a bigger heatsink.

Case Lian Li v1000 plus, cooler TRUE 120mm push pull.

EDIT I am keeping the same (stock) multiplier and just increasing the bus clock, currently at 230. This means I am increasing memory, HT and NB in sync. 4.8GHz was by increasing the bus to 240MHz. I may look at keeping everything stock except the CPU by putting the bus back to 200 but it seems to be fine as I am. Each 5MHz bus clock increase is 0.1GHz on the processor.

UPDATE

Just purchased some Phanteks through my paypal slush fund will see how they do.

The lower Cinebench at 4.8 may be due to my lowering the NB and HT slightly, also memory speed although that was about 1900MHz. Did not notice any throttling. Now my cooling may improve, I will up the volts a bit.

8350s are generally requiring less voltage for the same clocks, or rather higher clocks at the same voltage! :D

Not for me it doesn't. Does it matter what you encode?
Click to expand...

yes it does, or rather the settings you use to encode.
In the video settings you will find the default rf level it is set to 20.
change that to 18 or lower and see the CPU usage increase a lot,

Basically at the default level more time is spent on io than encoding.
