Ah ok thanks BTW anyone care to post some very high 4xAA 1920x1200 Crysis benchs with oc 5870/5870s? thanks in advance.

that easy...i can do that, give me 10 minutes

here we go, daily setting 5870 @ 950/1300

or u can go here : http://www.xtremesystems.org/forums/...d.php?t=236191

Ok man thanks looks like no big difference to me, maybe with future drivers that will improve. Then again the single card performance is not bad just the crossfire scaling bothers me especially in Crysis (40% only from 2nd card,thats really low)

I've found that on my Sapphire 5850, RTHDRIBL causes lockups/artifacting/instability at lower clock/higher voltages than any other tests I've tried (inlcuding FurMark).

For those with 1GHz+ GPU OCs, what voltage do you need for RTHDRIBL stability (full-screen/maximized, maximum details)?

http://www.newegg.com/Product/Produc...82E16814121349 I hope so we can finally get a unlocked freaking bios MSI makes this great tool but makes it useless because of the limits on the bios WTF. It is a pain in the ass to use to tools.

Here is the BIOS for the HD5870 with the 1800/2600 limits. Seems a lot of folks are pushing the 1200/1400 Asus BIOS limits already on water.

no problem here 1000/1300 1,225v

1.163v here, 1Ghz core, 1300 Mhz ram. MSI HD5870 flashed with ASUS bios and on water.

Here you go. This is with with adaptive AA on and 8x AF as well. Works pretty well if I must say so. 1000/1300 on the clocks.

Mine does fine through there at even 1.2v for 1ghz. Oddly enough what made me go to 1.225v was the Stalker: CS benchmark. It would lockup at 1.2v, but went perfectly smooth at 1.225v. Might want to give it a go after you get RTHDRIBL stable.

Enjoy.

Edit: I pulled this one right off my card, that's why it's a .bin instead of the original filename

Thanks for the tip, I'll have to give it a shot.

Ok, i've done some OC'ing last night.

GPU: 950mhz and Mem: 1300mhz @ Stock volts. I didn't go higher yet. Tested NFS: Shift last night and had nor errors or crashes.

BTW I'm looking at upgrading my CPU.
Which CPU would u guys recommend?

[Gaul]

@ soultaker = 5850 or 5870 ?
@ all = anyone flash msi BIOS ? please report here......

how to used 5870 with riva tuner ? add string ?

[jfer]

Could somebody flash a 5870bios into a 5850?
1600SP unlocked?

Don't think u can. We are all using the MSI Afterburner (which is built on rivatuner technology)

[Patch]

Seems to work. Did it last night on a Sappire card.

Kudos to MSI for this. I've never purchased a MSI product, but I'll start doing so if their reps keep up this level of involvement.

[Lightman]

For all those having low scores on theirs HD5870 - the problem is cards BIOS!

Fellow member AussieFX has sorted his problems after applying fixed BIOS from MSI.
I will try to get that BIOS posted here but I suspect that any other (up to date) BIOS will fix that issue!

[Oese]

low like what scores?

*wonder*

[zalbard]

Does the 1800/2600 BIOS have these performance fixes?

[CornerJack]

Results with Asus 5870 "voltage tweak"





i870 4GHz + Asus 5870 850/1200MHz



i870 4GHz + Asus 5870 1051/1350MHz @1.31v
It's max air



Impossible to use SmartDoctor...
I must use AfterBurner...
Soon watercooling and after... LN²...

nice, well try to oc, then i'll compare with asus bios.

or let me do...hmmmm



nothing special here.....1000/1300 , FAN 45%

[punkrockpolak]

Have any other companies released updated BIOS for the 5870?

[Patch]

Since I currently have one of my ASUS cards on water, I'll see if I have time to flash it to the MSI BIOS tonight and do a direct comparison on the same card.


Here's an hwbot link to what it does with the ASUS BIOS:

Like ~11000 GPU score in Vantage ...
