Anyone with the Gainward 4850? Whats your clocks?

Got Sapphire cards in mine, but as they are all refrence anyway...

Use RBE to edit your bios for max 1.2V under load and you should be able to get 700/1100 without many problems :)

can i use gpu-z to get the bios from my card? can u please tell me which numbers i need to change in RBE or do screen shots..

also do i need to touch this? ^^^

once i've edited it do i use winflash?
 
It is the 'clock settings' page in RBE you need to edit, and yeah you can just save your BIOS from within GPU-Z.

Under each clock setting there is a voltage.

The ones where the card is running at full clock speed you will need to change it to 1.2V (or higher, but the max you will get is always 1.2V).

Save the bios in RBE, then use the dos flash util (atiflash) to flash your cards (you can use winflash, but at your own risk!, I always flash from dos, takes a a couple of secs tops).

Command to flash from dos using atiflash is:

atiflash -p 0 newbios.bin

Where newbios.bin = the bios file you just created in RBE.

Also make sure you keep a copy of your stock bios somewhere safe (like on a thumbdrive etc.) then if something does go wrong you can always bung an old card in and reflash to a working bios (though you shouldn't have any problems).


Other thing to note, when you come to overclock you will need to disable Overdrive as it won't function with your newly edited bios. You'll need to use AMDGPU Clock Tool or something of that sort until ATiTool / RivaTuner and the like get support for the 4 series.

It is only the ones with 625/933 that you need to bump up, those are you 'full speed' clocks.

The rest are for UVD and Powerplay and as such can be left alone.

The ---- just mean 'default' so whatever is preprogrammed.

Just replace the --- with 1.200 :)

This is what my bios looks like:

I've edited some of the other clocks, but you don't need to, you can leave them all as they are, and just replace the voltages in the 'full clock' sections.

As you can see i've used 1.263, but you can use just 1.200, 1.210, whatever as long as it is 1.2V+, all you will actually get is 1.2V :)


My bios basically means:

0 = Boot = Stock clocks and voltages

1 = Powerplay = 160 core 500 mem, low voltage

2 = UVD = 500 core, 750 mem, low voltage

Everything else full speed max volts.

is this right? or should i set the UVD clock voltages too (clock 4,5,6)?

clock 00 = boot
clock 01,02,03 = low, medium, high
clock 04,05.06 = UVD low, medium, high
clock 07,08,09 = low, medium, high

right?
 
Hi there

Glad you guys are enjoying the cracking deal we got on these cards for you. :)

You will only find Gainward ATI graphics in stock at OcUK and the prices are very very good as you are finding out. :)

Are the performance gains worth the fiddling at 1680x1050?

I can pretty much max every game out with 4x AA, apart from Crysis (which I don't care about). Would clocking allow for 8x AA?

You can't use 8xAA at stock? In which games?

Anyway I have my card at 880/1150 and play everything with 16xAF and 8xMSAA at that resolution and framerates are great....as in 80-100+ average

ok. but i can't disable Overdrive when i untick the box and click apply it just puts the tick back on..

i've used AMD GPU Clock Tool to clock it but i've noticed the powerplay stops, the clock doesn't go back down to 500/750 when not in use, only will to get the powerplay working again is to do a reboot.

also in RBE 1.13 it as overdrive features, if overdrive doesn't work after using the edited bios then whats the point in having the overdrive features in rbe 1.13? lol
