Does Asus A7V8X have compatibility issues with Radeon 9700?

[alarmer]

Hello

Just bought my Hercules prophet 9700 pro and plugged it into my Asus A7V8X motherboard. The problem is that the system starts up but welcomes me with only black screen. Iam not even able to go to bios.

I have updated my Power from 300W--->350W------>400W but no help. I have the most reacent 1007 bios for my motherboard. No help either.

What I need to know is it my 3D card that is bad or my motherboard. Any suggestions?

I've have the same problem. I have the same mobo and video card. I set teh DRAM BURST to Auto and then it worked, but then I bought Age of Mythology and I had the SAME PROBLEM. So back to 0. If anybody has any ideas please reply

iirc there were problems with revision 1.1 boards & certain m/boards with x8 AGP.
things seem to be sorted with the ver 1.3 boards!

The only solution to the won't post issue is to RMA the card. It isn't so much a revision thing as the VPU (what ATI calls the GPU) that you got. The latter revisions are newer steppings of the VPU that increase the chances of getting an 8X compatible VPU or at least that's how it seems to me. People have RMA'd and gotten back the same revision and had it then work. Others RMA'd and got back a newer revision that didn't work, RMA'd again and got one that did work.

ATI really could have improved the QA on this one.

I have an A7V8X with a Radeon 9700 Pro (Rev 1.0). I can provide a few pointers to getting it more stable with this board (like raising the AGP voltage), but I hadn't even heard the DRAM burst thing.

Theres been a lot of FUD going about with regard to this, and from what i can gather it is in fact the motherboards at fault as if you try the new SIS 8x AGP video card it too wont work properly if at all in motherboards with this problem.
Maybe ATI have done some alterations to their card to improve compatibility with the offending motherboards not being released 100% AGP 8x compliant?
There was a thread up on Beyond3d forums where an engineer who is evaluating the 8x AGP spec with motherboards had found that Intel chipset motherboards were fine but some of the other chipsets had been implemented on some motherboards in such a way that they may not have been within the AGP 8x spec'.
Not to say the chipset was at fault but the way it had been implemented into certain motherboard designs.

If your board has problems i'd be inclined to send your motherboard back for exchange for a later revision if not another model.
If the 9700 works fine on all Intel chipset mobo's then id be looking at the motherboard.

So cct, you spread FUD about the motherboards instead of ATI? Is that any better? I would prefer the truth personally.

This issue is not unique to the KT400, it happens with SiS 8X chipsets too (including the 648 on the Intel side). Are there any 8X Intel chipsets? Who is to say if there was that it wouldn't occur on those motherboards too.

I don't see the nVidia 8X cards experiencing these same issues, but I'm not sure there are as many going around yet. RMAing the Radeon 9700 solves the issue, but I have seen people RMA the motherboard and it doesn't solve the issue.

This is definitely a Radeon 9700 issue from what I've seen.

Thanks for biting
The fact that Intel laid out the specs for AGP 3.0 (make of this what you will ) is not FUD. Neither is that certain MOTHERBOARDS WITH NON INTEL CHIPSETS have issues till either they are replaced via RMA or are fixed with a bios update to work round the problem.
This is not FUD, its fact and if you would like to take a look around you will find the same.
Also it appears from what ive seen that ATI too have been doing some leg work by replacing cards which have returned as the exact same PCB rev. - so it makes you wonder if ATI are just upgrading the bios which includes a workaround on the card and shipping them back out.

This issue is not unique to the KT400

I thought for a moment i was coming across as a zealot, sorry if you felt this - i actually have quite a few Via chipset platforms and wasnt dissing them, just some motherboard implementations of NON INTEL CHIPSET motherboards have had problems.[/quote]

, it happens with SiS 8X chipsets too

yes.

(including the 648 on the Intel side).

Intel platfrom - as i said, yes. Intel chipset - not as far as im aware. Only the independent AGP validation done by various respected engineers can vouch for this.

Are there any 8X Intel chipsets?

Motherboards? - Not as far i know you can buy now. There are INTEL CHIPSETS with AGP 8x being validated on boards now.

This is definitely a Radeon 9700 issue from what I've seen.

I agree with you - i look forward to seeing how the other vendors putting out such a card handle this power problem.

My Radeon 9700 will be going on a AGP 4x mobo (GA8IRXP) + Antec True power PSU so im not expecting any problems outside of what you can expect from immature drivers that im expecting.

Heh, im getting too old for this
Live long and prosper
Hope you find all the answers to this problem and will share them with us all so that others wont get caught out
If your still perplexed with my posts please let me know and i'll paste all my research linkys then maybe people can make up their own mind from their own viewpoint.

Warm Regards,

Chris

alarmer - Have a looksee here - ftp://ftp.asuscom.de/pub/ASUSCOM/BIOS/Socket_A/VIA_Chipset/Apollo_KT400/A7V8X/

Theres 2x newer bioses for your board and im hoping one of them will fix your problem.

Wish you luck
