***official amd 83x0 overclocking thread***

[GinG]

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.

4.9ghz is where it is at! lol

You will every time on a better board tbh...

I certainly won't make the mistake of buying a cheap board again.

I agree, if you class the Sabertooth as thoroughbred also. My last board was MSI P45 Platinum and had plenty of features, overclocking good too.

Listening to the feedback on the mosfets etc getting hot is there a few solutions people have looked at to combat i.e. USB fan like one here:

Just installed 8.1 preview, definitely improves multicore performance!

Without touching or tweaking anything Cinebench score gone from 759 to 778 @ 4.9ghz

 

[GinG]

Either that or Vista was seriously holding me back!

 

[teppic]

Have you noticed better gaming performance?

BF4 beta is hugely improved on Win 8 over 7, let alone Vista.

 

[GinG]

Just downloading the games now so will let you know

Also in Cinebench just managed to beat a I7 2600K @ 4.5 score:

Just bought a HD7970 Platinum off overclockers for £235
My new rig is complete

You'll love it ouzodan, just installed one in my rig to replace a 770GTX because of 2GB vram buffer on it etc.


Fire strike

GTX770 @ 1297 core 3705 Vram (max oc I could do on this card) - 7280

Stock 7970 Matrix Plat 1100core 6600 vram - 7420

Clocked by just 50mhz - 7578 This thing is brutal!!

 

[Cool Breeze]

7771 @ 1200Mhz This thing just keeps on giving...

 

[mx0range]

now i want a new gpu.. but it wasnt long ago i got the gtx 670

this thread has cost me well over £400.. so far!

My plat runs 1300 on the core no problem. These cards love voltage.

How much of that increase is down to a clean install ?

In software that works properly Win 8 will net you a 10% difference. Same goes for 3dmark tbh.

None of it. Windows 8 was designed to support the FX CPUs properly. The same thing happened with the Athlon XP. Windows ME etc hated it, XP supported it properly. There are a couple of bodged hot fixes for Win 7 but they don't work very well.

If you have an FX you must use Windows 8 as much as it may hurt.

Hi Moogleys, did you have to adjust any of the onboard voltages to achieve this?

Get another 670. Cheapest solution, epic power. You've got the board for it

This excites me muchly, I was holding off on getting one because the price went up a fair amount had a look this morning and prices were back down so thought I jump in & get one now.

Im already auctioning off my old 6850's

got any data ?
links to some comparisons maybe.

Personally I would like to see what difference it would make using something like handbrake.

Don't give a fig about 3dmark or BF4

Yeah I got some data mate firstly the FX series do not work properly in Windows 7. There are many reasons for this, but mostly it's because Win 7 simply does not work with the architecture properly. The most notable problems (IE the things people noticed and relayed back to Microsoft) were that the CPU acts erratically in Win 7). Most notably -

Core parking. The CPU will simply park the cores randomly, screwing up multi threaded performance.

Cache dumping. The CPU will dump its cache mid operation. You can read about both here.

However, even with the fixes it didn't seem to make much difference to me. AMD released Bulldozer after Windows 7 had launched so it was a bit too late.

Here is a 3Dmark Firestrike score of mine on Windows 7. Hardware as per my sig



And one using Windows 8.

I have overclocked a bit more since then but the best I could manage was 9020 overall. I'm now over 10,000.

Cinebench is another app that reacts well to the OS change. In fact, *anything* that wants to use the FX to 100% (IE all 8 cores) will see the same sort of results.

For 1300 my voltage is 1310. Everything else at stock settings. Tbh I see very little gains in game between 1200 & 1300 so use 1200 as my everyday clock as it runs nice and cool.
