b.ops not start with c.f. hd4870x2!!

[spl]

this is the error !!
please help!!
i try g27-28 same problem,pata sata same problem,with one card is ok but in c.f. not !!!!
the boot finish here !!

[cadaveca]

pls try "reset configuration data" within bios.

[spl]

I have not understood what I must make where I find the this voice reset configuration data in the bios!!

[cadaveca]

In pnp/pci configuration config, also check "pci-e complaincy" mode under advenced chipset config.

I boot fine with one card under P05 bios, maybe there is bios issue with 2 cards...

[spl]

nothing i try to change this paramether but the problem is the same!!

[cadaveca]

Hmm does one card work for u?

I think bios is the issue...there were similar problems with this chipset(x38/x48) with 3870x2 which new bios rectified. And it seems this issue is not confined to BlackOPS either. Many boards are not able to complete boot with 2 cards installed.

I´ve got the exact same problem. One 4870x2 works fine and if I plug in the second one BlackOPS ends with this message. Postcode 8b.

[Xello]

F***ing hell. I hope this is fixable, my whole setup is waiting for 2 of these cards..

[negev]

spl what kind of psu do you have?

3rd post down says 8b is power-related.. those x2's draw a lot of power

[cadaveca]

Uh, i hope it's not pci-e power that's the problem...

t.t.1200w

I checked power consumption with a power meter. With BlackOPS, E8600 @ 500x6 1.25 volt vcore and one card I had a consumption of about 370-380 watts while booting. A second card shouldn´t be a problem for our OCZ EliteXStream 1kw. But surprisingly power consumption remained nearly the same after installing card no. 2.

Uh, i hope it's not pci-e power that's the problem...

That was my first impression while dealing with this problem.

After several attempts I changed motherboard (ASUS Maximus Extreme), cpu (qx9650) and psu (I tried Silverstone OP1000 and Xilence 1200). With ASUS Maximus Extreme I didn´t get a screen when both cards were installed.

Funny thing is that the system itself was up and running. Because after some seconds I could shut down the pc with pressing windows key -> arrow up -> enter -> arrow down -> enter on my keyboard. That means that my system was in windows vista and reacted the right way - but without a picture on my screen.

I will have 2 cards soon I will test.

[btdvox]

Yeah this is a definite question for me! Im getting 2 board to CF

[negev]

Based on MusicIsMyLife's last comment, this sounds very much like a bios issue... its getting confused somehow and not initialising the display.

Good stuff, glad to know you're on the case

2 cards due to arrive today. Will test tonight in BlackOps and P5E3 Prem.

[btdvox]

^^ Let me know how it goes! Im between those two and a RE

OK. received 2 new 4870x2's today and after several hours of testing, I found the exact same issue as spl above. I didn't try any other bios than G28 but I believe this could be a BlackOps bios problem because the same 2 cards run in crossfirex on my P5E3 Prem mobo using bios 0505 . I used the drivers on the install disc that came with the cards. 8.8 beta did not work and the official 8.7 from guru3D did not work on my asus board. I tried all of these on BlackOps to no avail. Every attempt was stopped cold during post with the "AHCI Bios not installed!!" I disconnected all extra stuff on the board to make sure there was no power issues. 3DMark benching requires about 980 watts with 2 4870x2 and qx9650.
(2x1 gb, Vista 32bit).

Saaya,
Please bring this issue to the bios engineers.
Thanks!

F*** me, really?!

I guess this 1250w coolermaster psu wasn't a waste after all..
