HIS 5850(w/ Asus 5850BIOS) and Asus 5850CU Crossfire voltage question?

[20mmrain]

Alright check it out.... I finally got my Crossfire config all setup. I have a reference HIS 5850 Flashed with the Unlocked Asus 5850 BIOS.
I am running Crossfire in conjunction with that card and a Asus 5850 CU (Non reference version) But this card does have voltage control.

Here's my question..... Both cards are recognized in MSI Afterburner in crossfire. But the reference card (with the Asus BIOS Flash) is the only one that will let me change the voltage.

If I run each card by themselves.... they will both let me change the voltage but not in crossfire.

I have also tried Asus Smart Doctor. Believe it or not.... the only card that is detected there is the HIS (Asus BIOS) reference card. I see no option to look at the settings for the other card.

So my question is how do I get voltage control on that second card in MSI Afterburner?

I have tried.... (EnableUnofficalATIOverclock) Fix in MSI afterburner.

I have tried enabling it in the Settings menu of MSI AB

I have tried creating a .CFG file in my MSI Hardware profile's to recognize the voltage chip on my Asus 5850 CU.

I have even thought that possibly.... when I set the first voltage on the first card..... that because the cards are in crossfire both voltages will raise together? (This last part I don't know if it would be true if someone could clear that up for me?)

Anyway if someone has any ideas please shoot them out. Because as of right now.... I am stuck at a Max OC of 900/1176 and I am fairly sure that it can go way higher considering I am getting no.... signs of strain and my temps are awesome!

Thanks for the ideas in advance

I wonder if Afterburner has a limitation of not being able to read/access two different voltage controllers?

You know that's funny you mention that. I was wondering the same thing?

I could possibly join Guru3d forums and ask the creator I guess and that might be what I end up doing. But I guess I will see first if anyone here has a fix.

I mean 900/1176 overclock on those cards in nothing to complain about.... by all means but I have a feeling there is more to be had.

so what you guys are thinking is correct. it has a hard time adjusting 2 diff controllers on the fly. have you tried going to afterburner, settings tab and manually switch to the asus card that way?? turn off "set similar gpus" i have had to do that in the past and it worked. basically it allows you to oc/raise voltage of each card independantly. if they had the same volatge i.c. then you could change ones voltage and the other would match it but because they dont you may have to manually do it

Yeah it turned out I already had that disabled..... So I tried enabling it.... still no go. I am in the process of joining Guru3d to ask this question. Keep the suggestions coming guys but if I find out before we figure it out.... I will let you all know.

Bump because no response yet at Guru Forums and more ideas here?

Hey there!
I've got the same problem as you!
I've got two 5850s from XFX (585X-ZNFC and 585A-ZNFC) and I'm unable to over-volt the 2nd card (pic related). I can OC/OV the first card with ease and can even OC the 2nd, but not OV. The slider in MSI AB is just grayed out and unselectable (for the 2nd card). I've tried enabling the unofficial ocing, syncing and unsycing the cards, but nothing works. I've read that this is a pretty uncommon problem, and I'm beginning to think that it's because of the slight difference in the cards we have. If you google the two model numbers of my cards you'll see that they are quite different, both in layout of items on the board and even the heatsink. I know MSI AB cannot configure different voltage controllers, but for both of us they SHOULD be the same. :/

Please do let me know if you find a solution, and I shall do the same. I've got this post on a few other boards and even sent a message to XFX via their support page (lolwarranty).

Specs:
1090t
890FXA-UD5 (Latest BIOS)
XFX 5850 (HD-585A-ZNFC) in PCI x16 1 (able to be over-volted)
XFX 5850 (HD-585X-ZNFC) in PCI x16 2 (able to be OCed but not over-volted, as far as I know)

This is with voltage tool in MSI AB up and the cards syncing in the settings. :/

I had a nightmare with an asus directcu 5850.. I HATE that card and eventually traded it off... why? Smartdoctor is THE ONLY WAY I could change the voltage on that card and I suspect that program is not working for you because the asus is not the primary card (that software is junk).. I doubt you'll ever get afterburner to adjust the voltage on that card.. I tried EVERYTHING.. I couldn't even flash that card as it would give me a "ROM not erased" error. The EASIEST thing you can do is trade that thing of for a reference 5850.. I don't think I ever hated a card as much as that one.

How would one trade a card. It's past the refund/replace dates on newegg. Lulz, I've never had to do this. xD Thanks for the information btw, it turn out the fucking doesn't have voltage control and XFX DID NOT notify me of this, whereas MSI, Sapphire, Gigabyte all note when their cards do and don't have voltage controllers within them. :/

you could always just modify the bios to the votlage and clocks you want and do away with afterburner.

Oh? I was under the impression that the voltage controller is a physical piece on the card. What about flashing my BIOS to a reference one? Anyone have experience with that?

 

[ShRoOmAlIsTiC]

yeah the voltage controller is a physical piece of the card but it can be programed like the rest of the bios.

scroll down a little and youll find a bios I modded for my card. it ups the core voltage to 1.125 and default clocks are 825/1000 with ccc unlocked.

What I mean is sell it and buy another.. any way you can think of... but I thought you were talking about an asus, not XFX? confused now..

not sure exactly what card you have.. but my non-reference asus did have the voltage control, it just wasn't anything standard so I couldn't make it work with afterburner... but i also couldn't flash the bios on mine. You could always hard-mod the thing if you wanted. I just didn't want to go that far with mine.. I wouldn't flash to a reference bios.. you can try to edit the bios with rbe or something.

Hello

do you have modify the bios of the card for the voltage gpu on the his 5850 iscooler? by the Asus bios 5850 BIOS?

 

[erocker]

It cannot be done with the HIS icooler card.
