700mhz wall on HD4850 is smashed.

How come you're only running pci-e 8x?

[BeastNotro]

Asus P5Q3 Deluxe

Expansion slots 3x PCI-Express x16 (1x16 or 2x8)

So in crossfire he can only do 8x on that mobo.

As for artifacts guys it could be driver related as i remember when i had x X1900's in CF on default drivers when they first released them. I would get artifacts at default on 3d mark 03 and 06, but 05 was OK.

I like usuing 03 for testing OC's of cards and my PC for game stability. As for overclocking my RIG i run Orthos for at least 18 hrs without issues or at times 24 hours. I break in the system with orthos 3-6 hours at stock for a few days then OC.

As for video cards i just crank em up little at a time and tested with ATI TOOL and 3D Marks and Aquamarks (old i know), but good for frames and such... woot.

So as for some ppl in here no pencil mod was used to get 720-750mhz which is ideal for many users to have such speeds, but we need 100% stability.

Now there is a Leaked 8.7 Driver out there look for it in GOOGLE, try it out ppl let me know as my HIS card won't be in until this Monday (i hoping) its Monday.

Great score, Bakalu! How many volts are you running on that card? Are you using RBE?

Thanks

Which program (also version) specifically should i use to flash the modified BIOS ? I want to be sure it works with HD4850 for sure. Some say certain flash tools have problems...

Latest atiflash works.

[W1zzard]

there was never any evidence that any flash tools have problems flashing, just some people speculating as always .. but yes latest version of atiflash and winflash work great

[RejZoR]

Thx. Where can i get any info on what each "Clock info" number does?

He is running a single card in the proper slot for x16 operation, hence the question.

[RejZoR]

I don't get it. I've changed the values to 720 but it still shows only 700. GPU-Z used to check clocks. Also i can't even disable Overdrive now. It just enables itself back when i click ok...

[gurusan]

you have to flash back to stock, then disable overdrive.

[RejZoR]

I went the other way. Removed the Catalyst clean and left Overdrive alone. Works fine now. Stable at 720MHz it appears.

EDIT:
Running sweet at 750MHz. You just simply gotta love these RV770 cores...

[Bitgod]

Is there info somewhere on how to flash, winflash or otherwise, when both cards are in the system, or is this something only to be done with one card in the system at a time?

[Rattle]

use a bootable USB stick or a floppy with atiflash, winflash is garbage

atiflash -p 0 newbios.rom for first card

atiflash -p 1 newbios.rom for second card.

I got my HD 4850 today and popped on my trusty Sytrin VF1 Plus that I've used on 4 cards now. I'm already at 800/1100 with 1.3V via pencil mod and BIOS flash. Scored 15,059 in 3DMark06 with Vista 64 and a Q6600 at 3.52 GHz in my first run without any tweaks. Not bad for $150 and an old HSF. Hopefully I can push this thing to 850 but I won't be too disappointed if I don't get there. Thanks to everyone for the BIOS, apps, posts, and information. You're great as always. Now I need to find stuff to play since I blew through everything but Crysis on my 8800 GT.

winflash is garbage

No problems here.

[Bitgod]

Thanks Rattle. Flashed the first card. Odd, I can see in Everest, CCC, and GPUz that it's running at 160/500, but honestly the card temp has only dropped maybe 2 degrees from when I was running at 500/750 (which my 2nd card is running at) and the fan speed is the same. I did deselect the Enable ATI Overdrive in CCC.

EDIT:Take that back a bit, it was more than 2 degrees, it was about 7 degrees it turns out. Still, I thought there was going to be a bigger difference.

I'm curious, anyone tested the powerusage of stock vs 160/500? I'll have to see where my kill-a-watt has hidden itself.

Windows error.

Idle Vcore 1.25V.

No, It is sample, ASUS Vietnam gives us.

atiflash -p 1 newbios.rom for second card.

Winflash garbage, that's a bold statement. I use this program for over three years now, flashed dozens of card and didn't have any problems.

I agree Winflash is awesome.

I have flashed so many times I couldn't begin to count. and it can do both cards with a single reboot.

My 2d/3d does not work... It worked before... Maybe I do something wrong now?
My 2d/3d changes work only with stock/original bios...
When I try to flash with 160/500 in 2d it does not change to that at all, and it does not change to 625/993, it say 500/750 all the time...
I have try to disable overdrive, and enable it... nothing works with my flashed card, only stock/original bios works with changes in 2d/3d...
What can be wrong?

I give u my original bios and my modded one, can someone take a loook?
I Use RBE to do changes.

Original bios
My modded bios

Thanks

seems to be a tool to overclock the 4800 series over the limit !!!

[BeastNotro]

Can someone try that tool to see if it works? 100%

[jimmyz]

It does there is a thread in Video Cards about it.

I read other thread only a couple posts in it and it appears this program overrides the CCC file mod for the FAN, so what do ppl suggest.. FLASH bios ... ??? then use this program .... ???

Here is the thread you were talking about in Video Cards.

http://www.xtremesystems.org/forums/...d.php?t=193910

EDIT:

Just to add, does this program adjust the voltages properly???
