unlocking my 4870

[danneth]

Hey guys,

i have a xfx 4870 1024mb im trying to overclock it even though i have done it with the CCC overdrive its still showing stock clocks in cpu-z done quite abit of reading and it seems i have to flash the bios? but ive been searching for quite a while now with no joy

anyone help me out on this one???

hi there......


do you mean the clocks in GPUZ remain the same..??, CPUZ is um for the CPU

but no, you shouldn't have to flash the BIOS for a moderate OC.

Hi,

sorry on gpu-z, in the value page it shows the overclocked speed, but then under the sensors tab ( the one where you see the live clock speed ) its showing standard clock speed

can you throw up a screenie for us mate, a pic speaks a thousand words.....

hope this helps lol

ok....that looks right to me

at the top you have your ''current'' GPU clocks (OC)

& below you have your cards ''default'' clocks..

 

[danneth]

ye but if you look on the right hand side, where the sensors pick up the live clock speed, its still standard same with when you view it through CCC overdrive its showing standard clock speed, and the results are still the same on 3d mark as when i did it as standard to

hmm....??

that is strange, the default clock is 750mhz on your card is it not..

im not sure why it states 600mhz..??, have you flashed the card BIOS since you've had it..??

....you are also saying CCC is showing 600mhz as your current clock speed too.

3D clock are only supposed to kick in when the GPU is running 3D apps. Run a game or benchmark of some kind while leaving GPU-Z running and then check the graph.

it could be.......


i think his 3dmark results show that same 600mhz clockspeed to..??, surly 3dmark will only work off of the ''set'' 3D clock..??

still remains the same no matter what im running

i haven't flashed anything no mate, and yes the CCC is showing 600mhz to

download & run ''MSI Afterburner'' this has its own sensor, lets see what that has to say about your anomalous clocks....

[skunksmash]

right....... when you stress the card that ''core clock'' does not move, is that correct...??

correct

 

[skunksmash]

can i have a link to the EXACT card you have.....


there's a problem here & it could well be H/W related, if all apps are showing this ''600mhz'' its likely not a S/W bug.

there's certainly an issue here..... if it was a 2D downclock i'd think it to be lower than 600mhz (there's nothing on the web about a 4870 being that speed @ idle or load)

& even if im wrong & that IS the 2D downclock, it should revert as soon as stressed back up to 3D numbers....

how long have you had the card, is there a warranty..??

had the card around 2 months now, so will still be in warranty ye
