The cards use 1.05v in idle, and most cards vary between 1.1v-1.15v load depending on brand.

How do you know what the voltage is in 3D?

Urbklr · Jul 4, 2008

Multi-meter, check it while running a 3D intense benchmark.

If you leave those blocks like that, then they will stick to what the default is, 1.1-1.15v. I type in "1.25" in that space...and it gets me 1.2v.

Just make one. Takes 2 seconds. Easy to flash. I did it a couple times now.

I am going to lower my 2D clocks again and I guess use the MSI bios since it has higher voltage, or so he says.

Sorry I meant to say "how do I use those?"

You need to make a bootable floppy and boot off of it with atiflash and flash the cards bios. There is a how-to on here somewhere that walks you through it. Its easy.

Ahh thanks. My computer doesn't even have a floppy drive lol

You make/get a bios file (.bin), and flash it using either Atiflash, or ATIWinflash.

Edit: Use ATIWinflash, you can use it in windows. I use it through cmd, works great

Idle temps after fitting an S1 with a 120mm + 80mm fan on top. 24.1C ambient. With the MSI bios with 160mhz/500mhz itll be even lower.

Nice, what are your load temps?

Depends on the software. Which do you want? Also, both fans are still only @7v. So if i wanted to go deaf I could get it lower still.

BoOsTed SS · Jul 4, 2008

Well I flashed mine to 160/500 2D and 650/1000 3D at 1.25V.

In CCC I clocked it to 700/1075 and I only get to 43° load using the ATT 3d renderer.

Hmmm, ATItool artifact scan should heat it up nicely

Edit

BoOsTed - Remember, flashing it to 1.25v will result in 1.2v....the bios will not allow anymore than 1.2v

I know. I just checked my 3D temps at 700/1075 and it didn't break 43.5° out of all 4 temps gpu-z gave me. I'd say it is good to stay.

ATi tool tends to crash with these cards. The furmark bench is a great way to heat things up.

the guy cant keep up with the cards being released, same goes for tray tools, riva tuner, and the other overclocking utilities

I installed ATItool, and when it asks to install unknown driver, I hit decline. That way it doesn't mess with the card, so I can use the artifact scanner

Got a VF900, and a new MM. Give me a few hours till some v-modded results

...WoooHoooo

Nice. Should have gotten the accelero and a 120mm.

Let me know your idle and 3d temps. I had mine at 700/1075 today and checked for artifacts for 30 min. Zippo and max temp was 44°.

This is at 1.2V btw.

Darknova · Jul 4, 2008

Got my 4870 this morning, but I can't fit my Accelero yet as my RAM sinks haven't arrived yet...should be tomorrow morning, but still annoying.

Urbklr · Jul 4, 2008

@BoOsTed - I'm getting 40 idle and around mid 60's load at 1.35v, it is WAYYY hot in my room thou :banghead:

Here are my findings with the MM, and W1zz's pencil-mod.

1.85K - 1.21v
1.55K - 1.24v
1.25K - 1.28v
0.98K - 1.35v

1.85K is stock.

Urbklr · Jul 5, 2008

1.3v

Hi, can i flash my sapphire 4850 with MSI bios? Is MSI bios on the techpowerup vga bios database are the one that has higher voltage than normal bios? Is it running at 1.2v? Sorry i am a newbie here.

No it isnt running 1.2v. Youll have to mod it to that. The msi bios is good because it has powerplay properly enabled. Make sure you get the newer one.

oh, i tot somebody did mentioned about higher voltage.
