Is there any bios for the 4870's with 1 gb ram?

Here's one at techpowerup : http://www.techpowerup.com/vgabios/2...24.080819.html

Core: 800Mhz
Memory: 925Mhz

Don't know if it's the default or not

Nope, those are not reference clocks. I advise everyone to be careful about flashing your cards with a 4870 1Gb BIOS with DDR5 frequency above stock. 1GB 4870's use double density DDR5 chips and they are more sensitive to higher frequencies.

My Sapphire 4870 1Gb can't take anything above 920Mhz (3680Mhz effective, even with the fan on full 100% duty) without getting massive artifacts all over the screen. I've seen people taking 4870 512Mb cards as high as 4000Mhz, and while they're being successful with those chips, somehow I don't think the 1Gb versions will go that high without dying or without a voltmod...

I'd be very careful with that.

Then with atiflash I checked the current bios version of my 4870 and it sure was the Club3D one. So I figured maybe I'll try to reinstall it to see if it helps and I noticed that the Asus 4870 TOP BIOS was twice as large as my Club3D original backup. So my guess was that the original backup didn't quite succeed. I reflashed the Asus 4870 TOP BIOS on the card and it came back alive.

But I would like to have the original BIOS just in case I need it. And since it seems my backup isn't worth :banana::banana::banana::banana:, is there any other place I can get that BIOS from?

how did you reflash?

I just bought one of these and I was able to get 850 / 1150 last night with my stock BIOS that came with it is this good?

thanks!

works great on my sapphire 4870 1GB

stock bios @ stuck 950mhz mem

So is this Asus one the best, or this Diamond one, or this other one? :confused:

So is the only 1gb BIOS anyone has found or tested yet? I just got an ASUS 1gb 4870 and want to try this BIOS flashing but want to make sure I am using one that someone has used and succeeded with.

flashes fine via atiflash :up:

sapphire @ powercolor bios + after vmods.. stock cooler/air cooling

http://img111.imageshack.us/img111/2458/9601090lc2.gif

begs to be cooled by the phase

Wow amazing oc after vmod....highest I've seen yet.

Bet that flies...Voltage? Temps? Vantage? etc.

i havent monitored voltages yet.. i just went by trying different fixed resistors

temp is @ 40/below 40 C but full load is too much for the stock cooler/air

i can bench anywhere from 900-940 core/~1090 mem

ive never bothered with vantage

This the highest I can get on stock voltages, is it good?

Well, the question is what you hope to gain by flashing the BIOS.

My card is a reference design Gainward 4870(512), running very well, with a very bad fan profile. It alternated from 22% (silent) to the sound of a jet turbine, with little between the two. Idle was at 77 C. and load at over 90C. I wasn't happy.

You have a card that comes OCed and has a good cooling system. Are you unsatisfied with it? Is it too loud?

its not loud at all,the temp are good(44C idle,51c load),I OC limited to 800/1100..I have good air cooling and I want more OC..thats the main reason..

Hatori, Hows the voltage regulator and memory cooling on that card?

Just wondering because it seem's some have good gpu cooling but they don't put anything on the memory or VRM's and that's not good.

the voltage regulator and memory cooling are good,anyone can help with my problem please?

You can use Rivatuner 2.11. I don't think it accepts hotfix#2 (driver v8.55.1), but it does accept the previous one.

If you really insist on editing your BIOS, here is how I did it in Vista 64:

1) I create a directory called C:\Bios and put RBE 1.17, Atiwinflash (and files), and the BIOS in it.

2) I edit the BIOS with RBE 1.17 and save it with an easy name ("New4870bios.rom") in C:\Bios.

3) I uninstall the CCC drivers. It asks to reboot, I refuse and click on "cancel".

4) I open the Command Prompt and type "CD.." two times. I then type "CD Bios".

5) I am careful the HD is not running (red light is off) as I don't want anything that might interrupt the operation.

6) I type "Atiwinflash -p -f 0 New4870Bios.rom". (that is a zero after -f, not the letter O)

7) Vista asks permission to continue, I click Allow, and then wait. After it is finished, it asks to reboot, and I click Ok. If it is NOT successful, I will reflash immediately, and not reboot (though this never happened, and I've flashed a half dozen times already).

8) After rebooting, I install the drivers, and that is it.

BTW, how is the card cooling the VRM? Special heatsinks?

Think

I have the Asus 4870x2 and installed the latest drivers but the default speed for overclocking is 800 and 1000....I'm confused.:confused::confused::confused::confused:: confused:

in previous flash I got successful also and then the card died after reboot(screen go blank permanently)..are you sure wich bios ROM I should use for my card?

You seem to not understand. I suggested you use Rivatuner if you want to OC. There is no reason to edit the BIOS.

Im trying..I understand that you suggesting OC from a software,I just installed the new catalyst 8.11..are you know a software that support overclocking with this driver? cause RT 2.11 doesnt..

b.t.w

I know that on motherboards for example some bioses better to get more performance,Im just thinking that this is the same on GPU...in CCC I can OC the GPU max to 800MHZ and I see people here get better results..in my case,my current default bios that came with the card can limit me to OC from a software to those results?

EDIT:

ok,I uninstall the new driver and reinstall 8.10(non hotfix),now riva tuner 2.11 work perfectly.Im now 850/1100..there is a tool that find automatic the best clocks for GPU & memory? and how I check stability?

My number one test for stability is 3DMark06. I run it 2-3 times (I remove the CPU tests), and if it completes with no problems, there is a good chance the OC is stable. It will show stability problems before other tests. 3DMark Vantage is weaker for this. My second test is the Crysis Benchmark (Benchmark_gpu and Assault Harbor), but you can only use this benchmark if you have Crysis installed.

4870x2 asus top sapphire card

does anyone have the crossfire disabled in the gpu-z?
maybe its because of the asus top bios?
please just experts
thanks
