4870 ASUS TOP BIOS (upto 900MHz in CCC)

[LuxZg]

Nah. It was the drivers. I'm using the 8.7's again and XP and the problem is gone. 8.8's work fine on Vista64 though and they fly thru everything. 40FPS on Crysis very high 1680

WOW! Nice score for 1680x1050 in DX10&64bit
I get just 22fps in 1280x1024 with my setup in DX10/64bit/very high But it's still playable on those settings, so I won't be spending another 700-800$ for getting your framerates Specially since it's just one game

Yes, i dont know why this is more popular, but both bios's look good, im wondering which is actually better.

[purecain]

the fan profile is better on this bios.... keeps gpu at 60c....

Here's two runs with Crossfire disabled, single card. 1280x1024 very high and 1680x1050 very high. I think it scores the same as a GTX280 at 1680 very high.

Flashed my new Visiontek hd4870 to the Asus Top bios. Runs fine 3dmark06/Vantage.
Initially wasn't impressed as my 8800gts 512mb @ 800/2000 scored 15022 and the hd4870 Top bios scored 15331 - thought it would be higher.
However, then ran Vantage. OC'ed 8800gts 512mb P6307 with game fps 16 and 17. Asus Top hd4870 scored P8357 with game fps 24 and 25.
Here is a screenie after the autotune in catalyst. Failed 3dmark06 but passed Vantage though a little choppy at times. What an oven and what a card!


The XFX 8800gts will be going toEbay or here pretty soon, lol. Actually the e8400 too as my e8600 is in the mail =).

Thanks for the scores! Now I can compare a bit.. looks like I'll have to invest in a bit better CPU over time anyway

I just flashed this bios to Sapphire card, soon to find out is there any difference.

I backed up my original diamond bios and edited it with the same fan profile as this one but lowered all the fan percentages of the thresholds. I now idle at 60-61 instead of 77-78 at 25% fan speed. 25% seems to be the speed that works best for me at idle in terms of noise to cooling ratio. During gaming, the fan stays around 30-35% and I prefer it this way than the occasional burst of 100% fan speed from the original bios. My load stays under 75-76c

If anyone wants, I can post a screenshot of the profile

[LuxZg]

Please do! Sounds like it works pretty fine, since it's 800MHZ overclocked card..

Here is what I use, at idle I'm doing 62-63, full load in games it gets to 77 max

If you oc, might have to raise the fans a bit

Switched to Catalyst 8.8.
Atiwinflashed a couple of times to see which was the best bios for my stock Visiontek HD4870:

Visiontek HD4870, stock cooler. e8600 @ 4.3ghz.
Catalyst 8.8, Futuremark Vantage

Diamond XOC bios 795/1100: P8762 GPU 8783 CPU 8701 1st 2 tests FPS 24.87/26.62 Idle 78c Load 85c

Asustek Top bios 815/925 : P8775 GPU 8838 CPU 8593 1st 2 tests FPS 25.09/26.72 Idle 54c Load 65c

Asus Top autotune: 865/1090

Diamond XOC autotune: 835/1150

Impression: At least on my Visiontek card (stock cooler) the Diamond XOC bios would pass Vantage BUT did not entirely seem stable as would rarely artifact but annoyingly would stutter and jump frames.
On the otherhand, the Asustek Top bios was very smooth and stable. Additionally idle and load temps were much better. Seems to be the better bios with stock cooling.

Additionally from Catalyst 8.7 to 8.8 on the Asus Top bios Vantage scores went from P8357 (24/25) to P8775 (25/26) =)

[MaxT]

Holy crap, this is amazing.

Flashed this on my powercolor 4870 512MB.
Idle temps before 82: after: 60. Fan speed increased by 10%, so did the noise a little bit, but very tolerable.

Will test overdrive and 3d stability later.

Thanks!

I'm having a very wierd problem. I'm using this bios on both cards and 8.8 beta drivers. I didn't try with 8.7 yet but i don't know if drivers could be causing this.

Anyway, the problem only happens in 2d stuff (desktop) and i can't replicate it on the fly. It's very random. I just browse the net and stuff and for some reason the display turns off, both cards spin their fans at 100% and it just sits like that. Windows still works but i get no display. I have to reboot to get it to work again. It's very annoying and very noisy

Anyone else getting this crap?

Yes, I have a Sapphire 4870 also and while running 8.7 drivers twice I had my display go out and the fan rev up just like you described. Now, I changed my drivers to 8.8 official today and I lost my display four times within an hour same problem as you described. So, I flashed back to the Sapphire bios and I'm having no problem with the 8.8 drivers now... Their is some kind of problem.

Can I remove the OC limit if I dump my original bios and change it with RBE ?

Having exactly the same issue's, but they only started after 4 days of having cat's 8.8. Just flashed back to a newer Sapphire bios from tech powerup and I now have max overdrive clocks in ccc of 850/1200, this is a newer bios than my card came with. I had to use this one as my original bios I backed up would not load, although rbe reads it perfectly ok.

Yeah, I am also using that bios from TechPowerUp, I did not back up my original. But I am having no problems with it so far. Also, when I flashed to the Sapphire bios I put my pci express on auto, as opposed to 105. I doubt that matters though. I will let you know if I have any problems.

[8800's@over]

Let speeds card in 795/4400Mhz (Stable) has a problem?
It can reduce the useful life of GDDR5?

Cold cards.

same exact problem here what is wrong ? if i try to install anything over 8.7 system is unstable even if i am gaming or not .. anyone else having the same problem or fix for this ?

i am using his 4870 flashed to top asus bios and even 8.9 is giving the same problem while 8.7 is rock stable (winxp)

I was just wondering if this flash would work with the DIAMOND 4870PE51G Radeon HD 4870 1GB. I've noticed that most people using this flash have a 512 mb memory. Does the memory size make a difference?

Thanks,
Lee

[Rattle]

best driver since 8.6 hotfix for me and using the asus bios i havnt had any weirdness unless i installed the beta drivers.

no, you'll want to use a BIOS made specifically for 1GB models. don't use the BIOSes we're using.

Is it possible to flash bios from OS? Like it was with 1900XT to XTX?
If its not possible , is it possible to do it from bootable cd-rom? If yes please , someone , make a tutorial - i would really be thankful
