Default Asus 4870 Top Bios

By flashing the TOP BIOS to a 4870, the cap in CCC is raised from 790MHz to 900MHz and the default clocks are raised to 815MHz/925MHz (from stock 750MHz/900MHz). It also adds a better fan profile that attempts to keep your gpu at 60C. From what I've read at XS, the fan profile is much more efficient with noise than keeping your GPU at a set % all the time.

I've overclocked my new VisionTek 4870 to 850MHz/1100MHz with water cooling using CCC and this new BIOS.

To flash the BIOS download ATIFLASH from here: techPowerUp! :: Download ATIFlash 3.60 and the ASUS TOP BIOS from here: ReMOSitory :: mvk.tech :: NVIDIA GeForce GTX 280 GTX 260 9800 GX2 9600 GT 8800 GTX ATI Radeon HD 4870 HD 4850 HD 3870 X2 HD 3850 2900 XTX - MVKTech
Then get a USB drive to be bootable using this guide here: HOW TO: Making a USB Thumbdrive Bootable (thanks for the awesome guide sSupergrover)
Now boot and enter this:
ATIFLASH -f -p 0 *.rom
(replace *.bin with whatever you named the ASUS TOP BIOS)
The number 0 represents which card # it is. For a PC with one card just use 0. For a with Crossfire use 0, and then 1 (and then 2 if your crazy enough to have 3-way).

After you flash your card with any new BIOS you will likely have to reinstall the drivers, so now would be a good time to check my driver comparison later in this thread.

And if you want to save a copy of your stock BIOS just in case, use the command:
ATIFLASH -s 0 stock.rom
That will save a copy of the original BIOS as stock.bin on your USB stick.

The above method of making a backup will NOT work as ATIFLASH will only read the first 64kb of the BIOS. If you want a copy of the original BIOS on your USB, you can get it from: ReMOSitory :: mvk.tech :: NVIDIA GeForce GTX 280 GTX 260 9800 GX2 9600 GT 8800 GTX ATI Radeon HD 4870 HD 4850 HD 3870 X2 HD 3850 2900 XTX - MVKTech

Lastly, if anything bad happens (dead GPU) I take no responsability. But if something good happens (awesome overclocks), I'll take full responsability.

(If you do happen to brick your GPU, follow this guide to unbrick it: techPowerUp! :: How to recover ATI Radeon HD 4870 from bad BIOS flash)

Wow thats handy.

Although I'd only try this if the cards were watercooled as I doubt its safe to take them much over 800mhz on stock cooling. I'd pay special attention to keeping the memory and power regulators nice and cool.

Anyway cant wait to see some 4870 results of anyone over 800mhz.

The BIOS are designed for the ASUS TOP card which uses the stock air cooler and a custom fan profile. As far as I can tell, everyone who has used this BIOS has been perfectly stable at 815MHz and has been able to clock even farther (worst that anyone reported was 825MHz).

Thanks. Both of my cards will have flashed BIOSes once I receive my full coverage EK blocks, in about 2 weeks.

Thats good. Hang on a minute-have you gotten rid your 8800 GTX for one of these? I knew you'd crumble eventually Anyway if you could post some gaming impressions at your oc Id be really grateful!

Yep I couldn't resist a new GPU, and for only $250 with a free copy of GRID (+ Enzotech sinks) I had to get one. After I see if anybody I know locally wants it I'll probably be posting here and RFD and XS too if I get enough posts before I sell it.

I'm just installing games now as I reinstalled Vista so I wouldn't have to deal with any crap left from the nVidia drivers. I did play Crysis before I reinstalled though. 1680*1050, everything Very High and 2x AA. It was perfectly playable and looked awesome. I'm also going to compare tweakforce.com's 8.6 and 8.7 drivers in Crysis to see which one runs better, I'm guessing 8.7. So results when I've gotten a few games installed and updated.

Very nice CanadaRox! Running crysis on a 4870 at very high speaks for itself really.

Maybe I should have saved for the full cover waterblock. I couldn't stop myself buying another 4870 when I saw the deals last week, but it will be sometime before I can afford to watercool now.

I just modded a copy of the TOP BIOS so that it has the default clocks. It also has the more effective fan profile as well as the 900MHz limit in CCC (theoretically). I'll test it later tonight, so use at your own risk. But of course I wouldn't even bother testing it if I thought it wasn't going to work.

XG 8.6 vs XG 8.7 vs 8.6 vs 8.7 will start as soon as I've got Crysis updated to 1.2. I decided to include the stock drivers as well. And if I can find my Office 2007 disk I'll make some fancy graphs to go with it!

For those interested, the modded XG drivers can be found at TWeaKFoRCe.CoM your source for the latest Video Drivers and has modded nVidia and ATI drivers for XP 32/64 and Vista 32/64 (+ mobile versions).

Looking forward to this trip into the 4870 twilight zone. Keep us updated

I did a quick test of the BIOS and realized I actually put the TOP fan settings onto the stock BIOS, so it doesn't have the higher clock limit, but it does have the better fan profile and it does work. So for those looking for a way to keep your 4870 a bit cooler without it being a ton louder, that bios works well. For the driver testing I'm going to run the test first at stock speeds with 3 different time of days (0, 8 and 16) and put that on a graph with the average. Then I'll do the same with the TOP BIOS at whatever max overclock is artifact free for all drivers. All tests will be run at Very High at 1680*1050 with 4xAA and in DX10/64-bit mode. I'm also going to install SP1 as it comes with some important update relating to Crysis or something.
