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

[Mathematics]

I just had another go with CPU overdrive auto-tune in CCC, I gave it 1.48v Core and 1.7v Dram, let it run to 5000mhz.

Now when I try to apply 4.8ghz, it isn't doing anything, I'm I doing anything wrong?

Makes single threaded performance much better for us PD users

Let us know how you get on bud, and draft a installation guide for us newbs

If this works then it could get VERY interesting! Great find.

Do not panic Maths, I found the same. It has something to do with the driver version I think not working properly with overdrive. It is why I stopped messing and waited for Panos' guide.

 

[Mathematics]

Just tried the Stilt download, that didn't do anything either lol

Cheers Th0nt, will keep my eye out for Panos' guide.

How do I update my Bios?

I've downloaded the files from here:

http://support.asus.com/download.aspx?SLanguage=en&m=Crosshair+V+Formula-Z&os=8

How do I run them? My computer won't open a CAP File.

 

[gpuerrilla]

If you have an asus board put the file on a USB stick, select in BIOS the EZ flash option.

Ok mate, thanks!

Shall I put all the 12 bios update files on the stick and the 2 bios utility?

Nikki, I remember seeing this a while back. Doesn't it just improve performance only in SuperPi? Is there any benefit in anything else?

I'd love to see before and after runs of cinebench in single and multithreaded mode to see it makes a difference.

I think the biggest limitation we have is the shared FPU between 2 cores.

 

[nikki5974]

you might be right alex ill do some proper testing later in week like an oven in my house with heating on

got 14m15s 32m super pi knocked 4m30s off

Yes, you do it wrong.

As I wrote to my little guide few pages back, do not try to use both CCC Overdrive and AMD Overdrive at the same time.

They are trying to overwrite each other, competing and nothing will be working.

The best solution is to uninstal the AMD Overdrive. Turn off CCC Overdrive.
Flash your BIOS to the latest version, deleting the settings in the process.

Start fresh.
Have everything on BIOS default, including APM & C6, C1E etc.
TURN OFF ONLY THE TURBO.

Put the CCC Overdrive to find your CPU speed.

If not happy, go to BIOS, raise the CPU NB to 1.35. NO MORE!!!!! (you have it on 1.4 something).

Raise your CPU voltage to 1.48 (if you have watercooling, or else stick to 1.4).

Go back again to CCC Overdrive and let it find the speed. If you see it going over to 5200 or more. Stop it. You will not be able to do it from there that high.

You need then to go back and do it with the old way. Through BIOS.

If you have an UEFI board, then do the overclocking with your manufacturer tools.

Simples.

Cheers Panos!

That Stilt download is impressive, knocked 7 seconds of my SuperPI score for 2M (now 39s @4.4ghz) and added 260 points on CineBench to 701 points @4.4ghz, that is indeed impressive!

I wonder if this patch helps stability testing on IBT/P95...only one way to find out

 

[gpuerrilla]

Wow interesting cinebench boost there!

That's what I thought, might have to slip this file into the start-up menu as it turns itself off when you restart/shut down.

Hi Maths, so without the Stilt, what score are you getting on Cinebench at 4.4 GHz? 441 sounds a bit low.

Have you run the single threaded cinebench to see if there is a difference?

 

[ALXAndy]

I'll try that in a bit...

Just dropped £250 on this:

AMD Piledriver FX-8 Eight Core 8320 Black Edition
Asus M5A97 EVO R2.0 AMD 970
TeamGroup Vulcan (2x4GB) DDR3 PC3-19200C11 2400MHz

Does anyone know what sort of overclock I should be looking at on the stock cooler, and any recommendation of a decent after market cooler to go with this?

On the stock cooler? 0. You'll be lucky if you can stop it throttling at 3.5ghz tbh.

I could not hold 4.2ghz on a Corsair H60. In fact, even at stock speed the Corsair ran dangerously close to throttling.

You're going to need a big cooler if you want to overclock. Look out for a refurb H80 or H100 mate, or just wait until you can afford one. It really isn't worth buying anything else really.
