[OC Nub]

Trying these cards in my new rig. I want to break 30k in vantage and 06, something I couldn't do with my P55, I'm almost there in vantage.

[snoro]

i am sure you can get your card running @ 1ghz, you mught just need more vcore but most 5850 and 5870 can do it. Maybe also a suicide(depending on what voltage it need for 4.5ghz) run at 4.5ghz for your 920 could help also.

new driver..8.69

ASUS voltage tweak 5970 bios link at first post does´nt work.
Please upload it somewhere again.

5850 @ 1050 / 1250

[sl4ck]

Mine Sapphire HD5850 works very well up to 1000-1200 @ 1,2v with Asus 5850 Bios watercooled and catalyst 9.11, 9.12 and 9.12 hotfix.

When i try 1050-1200 even with 1,4v or 1,45v it completes all Vantage tests: GPU, CPU and Features, but in the end when it should show the score the PC hangs in a black screen and only reset solve it, this happens every time.

Strange thing is that it completes all tests without a problem, the problem is to show the score with a hanging black screen.

Can anyone help me?

Could you please link me to the stabliest and more overclocker bios?
Some say MSI bios is better, but in my case i think it's worse.

My goal is to reach at least 1050-1200 vantage tests completing score, once it runs all.

newes ATi 5870 bios is the best for daily use air cooled.

I didn't like Asus bios, worse OC then MSi even using 1.40v and more unstable.

I went using msi AB but the core clocks never change to the setting on the slider when i hit apply.. the mem, fans, voltage all change except core clock. wtf?

HA! Missed this one!

@Dan7777 if you use msi afterburner you can go in the config file and change the value of enableunofficialoverclocking from 0 to 1 and it will let you go for more than the 960 core 1445 1175v limit of your bios and it with work with every card.

Wow, very nice run OC Nub. I'll be tagging along on your heels once I get my 5870's installed.

What is that??? 3845xxx i7. You always get the good ones...

holy crap man. Thats really good core! All I can seem to get so far is : 932/1309/ 1112v

i went as far as 1.2v but core seems to bust around 950



that msi kombustor tool is great for checking fast if your clocks have any future.

chad what is your ambient air temp and gpu temp and the voltage?

[Lightman]

These cards clocks nice

Here is video of my card cracking some passwords (very GPU intensive task).

HD5870 (1.125V version also called - high leakage)
1107MHz GPU @1.312V
1248MHz Mem @stock

Ambient temp during that run was about 60F. The case I use is strictly for performance so its very loud, I used 1.26 volts for that run, card idles around 26C. I run 950/1100 for gaming at 1.12 volts

And single HD5850:

What Bios are you using?

And is this stable for gamming?

I have a powercolor 5850 with watercooling and i want to overclock it , what should i do to get near your values?

But i never flashed a bios and i read it could damage the graphic card

I use Asus 5850 bios, but this frequencies are not stable for gaming. For gaming I set the card 1030/1200 - 1.26v, but for this bench is 1.5v (but water cooled) with Smart doctor utility.
About the flashing don't worry, I have flashed my Sapphire so many times and I don't damaged it yet
You can read this post and if you make everything right there will be any problems.

Wanted to clarify something real quick, I have flashed bios's before...just want to be sure I have it right.

I'm running crossfire 5870 cards, SO:

Uninstall video card driver & CCC before all of this?

Ok, Use GPUZ to make a backup copy of your current BIOS & SAVE IT.

FLASHING:
Plug in a USB drive to use, install & run HP USB disk Storage Format tool.

Select the USB drive, in the "file system" drop down box, pick FAT32.
Click "Quick Format". Click "Create a DOS startup Disk, using DOS system files

located at and click the "...." and direct it to the BOOTFILES folder (Boot Files

HP).

Click START.

Once done, copy the ATI Flash & ASUS BIOS onto the USB Flash Drive.

Restart the PC & Boot from the Flash Drive.

Once Booted,

Since I'm running crossfire, type in:

atiflash -i

This will tell ID# for each card.
one being 0 and the other being 1 (depends on slot number or just amount of cards installed?)

THEN, type:

atiflash -p -f 0 bios.rom

Reboot at this point with only the 1st card flashed? and then flash the next card?? or flash both at same time??

ALSO, I noticed in a NON-CROSSFIRE post (First link to flashing) that instead of -p -f it is -f -p ..... does this make a difference?
IS the -p -f order important? Is the -p -f the correct order for crossfire?

(Sorry for all the questions....don't want to fubar it)

[zalbard]

You got everything right!
And the order of parameters does not matter afaik.
Also some people flash their cards in CF one by one removing them from the system, but it is not necessary.

[ZL1Killa]

SWEEET. now if I can just do it right....LOL.

So flash one card, reboot back into the USB stick, flash the other, reboot into windows & re-install everything?

[zalbard]

Pretty much.

[chad]

I think this is the most i can get out of this card...I really wanted a 20000 GPU score!!

Finally I've got 22k, HD5850@1137/1215, W3520@4664, Win7 x64

[deachus]

Here's my personal best so far with my 5870. I haven't hit a wall yet on core or memory so I will keep pushing. I am currently running a stock card with stock bios and stock cooling.

XFX 5870 1GB XXX Edition - Stock Cooling
Core i7 920 Batch #3913A330 - Water Cooled
P6T Deluxe V2 ~ Bios 0006
Kingston HyperX 2000Mhz CL8 3x2GB Elpida Hyper
Corsair TX850 PSU

I am only using MSI Afterburner for both voltage adjustment and overclocking.

Will keeping pushing. Looking to get a nice full cover block for this card once I max out my clocks on air. A nice cpu with a higher multi would be nice as well. This Board has a bclk wall around 218.
