BlackOps: 4870 and 4870x2 POST problems

[saaya]

Hi Guys,

First of all make sure you use BIOS G30 or newer, there was a vga BIOS incompatibility problem with those cards on a couple of boards, ours included, and G30 and newer fix that problem
It seems that using only 2 6pin vga power plugs can cause the cards to not boot reliably or run unstable, at least in the first pciE slot on the blackops.
Apparently it might work fine if you use only one card, but as soon as you use a second or third card you need to use an 8 pin and 6 pin power plug and not just 2 6 pin power plugs.

So remember to plug em good and give em all the juice they need if you want them to run xfire and clock high

I'm having problems with a single 4870 (sapphire flashed to asus top bios I think, it's not my card). This is in combination with my blackops and it happens on all 3 slots. I'm using 2x6 pins cause this card doesn't have an 8-pin. I'm already using bios G30 so I'm thinking it might be the card itself. Just wondering if there are other known cases of these cards not working with G30 bios?

[saaya]

not that i heard of...
so it doesnt boot at all?
but it boots on other boards?

i know that there was a problem with the asus 3870x2 card, but that card had issues on asus boards too, there was something wrong with the VGA bios iirc...
but besides that i havent heard of any issues...

[Gendo]

I'll investigate further tomorrow. It wouldn't boot last night but I was also running the cpu on dice. Now that it's on air it boots fine with bios defaults. But last night I got a variety of debug codes: ff with fans spining, all fans spinning but no debug led, b2, b3, a0 and beeping. basically the whole bunch. I even tried a different psu. More will follow tomorrow, and if I feel confident I'll throw some more dice on the cpu and try it again:p

edit: forgot to mention that last night everything was running without any hassle until I removed my 9800gtx and put in the 4870. the sh*t hit the fan when I changed gfx cards.

Can someone tell me why my 4870 isn't working on my blackops? =o)




However, the main reason for my post. It's regarding pcie clock stability with the hd4870x2. When I use a single 4870x2 my pcie clock can't even reach 110mhz, however with 1, 2, or even 3 4870's I can get to 125mhz and pass all the futuremarks. On the single hd4870x2 or any other combination where the x2 is in the slots, pcie locks up at anything near 110mhz. I'm bummed again! =o(

[Gendo]

It must have been one of these 2 things: the board got to cold from the dice while switching gfx card. OR it wouldn't boot because the gfx had too high values flashed into it. Cause on air it booted without any problems, the only problem I ran into was that the core and the mem had too high clocks that resulted in 12500 3dmarks06. I know that an 4870 combined with an E8600 @4500Mhz should not result in this so I started playing with the clocks and now I get 17700 3dmarks06. So i flashed a new bios into it and I'll once again try it with the cpu on dice this evening or tomorrow. I'll keep you posted.

Alright, G30 or newer, meaning there is a G31/32 etc? Where?

hmmm sounds like a limitation of the PLX chip amd uses on the 4870x2
Or do you know if it can be clocked higher on other boards?

yes, thats all i could think of as well...
or maybe water in the pciE slot? but the card was on air right?
and the board wasnt that cold right?
hmmmm

I haven't personally been over 110mhz on the pcie with the X2. However, I do have some friends with ASUS formula brand boards who can generally get around 120ish. Figured I'd bring it up incase you guys had time to look at it!

[Gendo]

Well I'm happy to report that everything is working fine this time. I still don't know if it was the board that got cold or the clocks on the 4870 that were too high.

But hey, it's working now so what do I care

hmmmm did you try bumping up nb and sb voltages? did they maybe mod their cards? higher gpu volts should help in getting the pciE interface clocked higher...

good to hear

MY 4870x2's came today, and i've spent the last 3 hours trying to get them working properly. The current problem that i can't seem to get rid of:

[saaya]

wow, looks like the cards are way out of sync there...
is that with the latest drivers?

[KingGnome]

are people still having problems with these cards? I was thinking of buying a sappire 4870 tomorrow maybe the 4870x2 if i feel like dumping that much money in a card.

[cadaveca]

On BlackOPs, yes, we need a proper bios for 4870x2's, but G32 does work semi-ok...

[tripgood]

On BlackOPs, yes, we need a proper bios for 4870x2's, but G32 does work semi-ok...

I have 2 BlackOps boards with dual 4870x2 cards and have not had a problem since G30 came out.

[cadaveca]

So? We need an official bios, not beta...no support for end users with this board and 4870x2...is not good. I am glad your config works, but mine does not.

[KingGnome]

Which card di you get then? I was thinking the Sapphire 4870x2 or the aus 4870x2 with the trifan.

Either one would be a good choice.

hmmm semi ok? what problems are you having?

and yes, there should be a public bios with 4870x2 support, ill ask the bios engineers

[cadaveca]

honestly, I don't know what the root cause is, but this bios is very flakey for me. P05 much more stable.

Also, dimm read delay and such varies on boot, without reason, making some boots ok, some not, when above 550FSB. 500FSB requires more real voltage than P05. PL8 @ P05, 1.25v. G32, 1.45v.

[saaya]

wow, really? same Trd?

[Broken]

So is there going to be an official bios that has support of two 4870X2's or what? I hate being mister negative but after two months of " yeah new bios is coming out soon" makes me think otherwise. That and the obvious reluctance of posting in the threads about a new bios. (Is the Black Ops the only X48 motherboard without official support of two 4870X2's, or is it common practice these days to rely on unsupported fixes?I know you are working hard on your new bread and butter but please don't forget those of us that have not jumped on that bandwagon yet. Realistically these should be easy fixes no? I can live with having my board not showing correct VTT as I found out about that here, or revised GTL ref table or whatever tweaks were planned... I would however like an official bios that supports two 4870X2's as I plan on getting another soon and don't like to hear from tech support that too bad, G30 is not supported. My system is running rock solid now that I have changed from the OCZ to G.Skill HZ dimm's so I don't foresee a problem, but you never know.

Thanks,

Yep. I've it left at as issues with the read fine delay....one boot 4/4/7/7, next boot 0/0/4/4...(dimm=1/2/3/4)


Of course, the 4/4/7/7 is not stable, this issue is present even @ 333mhz FSB, and is causing issues. Nothing I adjust affects this it seems, and manual setting is of no use, as it seems read delay is set at boot, and bios adjsutments merely add/subtract from what the bios sets.

i already pushed for a P bios for Blackops with adjusted VTT reading and official 4870x2 support, im sorry its taking so long... its not me holding it back

sorry, i dont get what you mean...
you mean when tweaking the memory clock skews it works, but once you shut down and boot again the same settings are not working anymore, or the settings are reset to default, or changed?
