Topic: ATI Mobility 5870 Overclock ? (Read 2643 times)
Yeah, that can bring you some serious giga hashes.
Go and try Radeon Bios Editor http://www.techpowerup.com/rbe/
There is a tutorial, see link posted above. Maybe you can do it with mobile ATI as well.
It worked for me with no mobile version.

I think in BIOS you could only overclock CPU and RAM, but the GPU.
The problem ist the mobile version. BUT: Are you sure you want to mine bitcoins with a notebook? Even if you run a miner at GPU 750 MHz, the GPU itself becomes extremely hot. Running this for hours or days will bring your small notebook fans to max. This is not good for your ears and your hardware. If you want to mine seriously, buy a big tower rig.

BIOS is something generic: basic input/output system. All hardware has a BIOS. What you are talking about is the front end of the Motherboard BIOS.
Yes, I'm talking about motherboard BIOS. Of course you can change the ATI BIOS as well, check out my link above. But this is manual cheating in the BIOS files with flashing the chip and not just clicking around and chanage any values from BIOS GUI.
But yes, you're right.

thx for answers!
i tried already:
AMD GPU tool and MSI Aferburner
but both don't work
amd tool says no hardware detected
msi tool hangs and have to make hard reboot
i think i need a bios oc method but nothing found....

Mobilities are quite complicated in getting them to overclock.
A) If it isn't a reference card it can effectively be impossible
B) Sometimes is BIOS lock in which case you can either modify your bios or find an already modified one to flash it with
C) Try other software like MSI Afterburner

Hi Everybody,
first i am new and i like this forum very much!
I have alienware m17x r2 with ATI mobility 5870 and i mining at the moment with that...wait for other hardware witch already bought.
My first question here is:
How can i over clock this Graphic Adapter? i have in Catalyst in windows 7 no option for override(oc).
I saw that its possible to oc from standard 700x1000 to 750x1000.
Do you have any ideas how is that possible?
thx a lot
with peace

The 5870M can be overclocked using the AMD GPU tool. If you want, I can google it for you.
Hi,
check this out: http://forum.bitcoin.org/index.php?topic=11087.0
I'm running a HD5870 at 950 MHz and 300 Mem Speed having at least 418 MHash/s (Ubuntu 11.04). With WIndows systems you have better overclocking possibilities.
I tried even 980 MHz but the system was extremely unstable at a hashrate of 432 MHash/s.
