For reference, my system specs are under my avatar.
Received this card like a week ago, but had some problems with it not fitting inside my case, problems that are luckily solved now. Yet there appears to be a bus interface problem now, let me describe it.
Here are my gpu-z screens: master and slave.
Notice how the Bus interface says "PCI-E 2.0 x16 @ x4 2.0" on first and "PCI-E 2.0 x16 @ x8 2.0" on second.
I first thought this was a power-saving feature so I run the "render-test" available if you click the ? next to the bus interface specs, but neither the x4 nor the x8 would go up to x16 after 10 minutes of testing and I found other people's gpu-z 5970's screenshots on the internet that do show x16. Both Trixx and CCC show x4, although CCC also specifies that the max bus setup is x8.
Notice how my motherboard has only one pciex16 slot, as the second one is a pciex16 running at x4. But that's not the issue as the card is plugged into the pciex16 one. Yet it's not a motherboard issue, as I have a Sapphire HD 6870 that I've tried and its bus interface value is correct: PCI-E 2.0 x16 @ x16 2.0.
My bios version is F7, it's the one that came with the rev 1.2 of it and the last one available before the F8a, which is a beta bios. So I don't really want to upgrade it to the beta one.
Init Display First was set to PCI Slot by factory default so I switched it to PEG to see if that would change anything. Before you ask, the card was already running on M.x4 & S.x8 with the PCI option, and it's still the same with PEG.
Tried cleaning both card socket to the mb and the mb socket itself with isopropyl, as it has helped me some time before with my RAM issues. Nothing.
Also, I'm currently using the 13.9 WHQL drivers (did a clean install, using guru3d DDU), as the 13.11 betaV9.2 ones were giving me screen artifacts and controller hangups every 3-5 minutes, and even BSODs. Had these driver issues only with the 5970, as the 6870 is working perfectly.
Here's the rarest thing, though. I tried running Furmark (Full-screen, Benchmark preset:1080) and I get around 3530 points (score link) which is around the same that other people get with their 5970 so there's kind of no performance issues, despite the x4. Results show one gpu only though, and I don't know if it's an issue, as this is a dual gpu card; opinions on this?
My only choices, known for me that is, left are:
- updating my gpu bios to the one known best for fixing all the problems, this one. I read that my current one is known for being a buggy one, but I know if that will fix my x4 issue. If I end up doing it, which I don't really want to, should I do it with atiflash & msdos or through atiWinflash?
- reverting my catalyst drivers to something even more stable, something like 13.1 or 13.2, as the gpu-z photos I've seen that had x16 were using those.
- trying with a different PCI-E connectors or even a different PSU. My PSU is modular, so PCI-E connectors can be changed, to see if there's a power supply issue (5970 eats around 294W, whilst the 6870 is only about the half, so maybe that's why I see no issues with its x16 against the 5970's x4?). A friend of mine might be able to lend me his 750W psu, to see if the issue is my psu itself.
I think that's about it, any suggestions and/or help will be sincerely appreciated. Thanks in advance
