I had a system with two nVidia 7600GS Graphics cards in an SLI configuration on a Gigabyte M590 SLI motherbaord. nVidia 590 chipset basically, PCI Express and all that. PCI x16 v 1 (or whatever).
But little did I realise, those cards weren't HDCP compliant.
Wonderful for everything else, and The Sims 2 was flawless for me.
Getting a Blu Ray drive, I was told by PowerDVD that I need HDCP compliant graphics cards, so I ummed and ahhed for a few months about ATI vs nVidia. I wasn't quite sure about ATI, I didn't think they were that fantastic compared to my rock solid nVidia based system.
But I figured I'd take the plunge, and get a HD 4670. Half the cost of an nVidia 9800GT and probably just as powerful, and I figured, why not.
Try my first Blu Ray disc with PowerDVD, and it starts playing, get lines on the screen, you remember in video editing when you try to go interlaced and you see each line out of sync with each other? Kind of like that. Then black screen. Ok fair enough, problem with PowerDVD.
Try the Sims 2, and the graphics stutter, the layers disappear, sometimes Im left with just floor, or random flashes as you roll around the screen.
Somethings amiss here.
Either the 4670 isn't as great as 2x 7600GS, or I've made a serious mistake. Power supply is 500 watt. 2 CD Rom, 4x1Gig of RAM, 3 HDDs, and a Dual Core Processor. Never been a problem with my two graphics cards. Maybe the HD 4670 just needs a PCIe x16 2.0 to work properly, in which case, what was the blooming point of that?
Any thoughts? This really is quite frustrating.
I'd like to know what Im doing wrong here.
Hopefully you'll tell me there's no reason, must be a substandard graphics card and that it should easily beat two 7600GS hands down, in which case, I'll send it back and get my money back.
While it shouldn't be a problem, try messing with the drivers. Remove everything video card driver wise, and try reinstalling the card. You should also try testing the card in a different computer. DOA cards happen, perhaps thats all you have.
It's an Akasa AK-P050FG7 500W PSU. It's a couple years old, but it's never given me a problem. The fan on the card is running really fast, but the card is quite cold. It's not even warm. The 7600GS which was fanless ran incredibly hot.
Maybe I should stick to the hope that it is quite simply a DOA card.
When I opened the box, there was no seal on it, the inner tray was ripped, and there was a finger print on the fan. Other than that, nice looking card.
I've removed the nVidia graphics driver, the only thing I havent done is completely remove all traces of ATI and start again from scratch.
Try booting into safe mode and run driver sweeper, I went from an Nvidia 7300LE to a 9600gt and had no problems. Just boot into safe mode, make sure it's checked to only look for nvidia graphics drivers, scan it, clean it, then reboot into normal mode, reinstall latest drivers from ATI and see how that works for you.
If you are concerned, may want to do a backup of your main files though.
I do tend to think the idea about removing anything nVidia related and trying again is a bit of an old wives tale. The idea that Windows will see an ATI card, but see an nVidia driver and try and use that, or have the ATI drivers try and use non linked DLLs and system files a bit far fetched.
But hey ho.
I'll be sending the card back assuming it's faulty. The box was opened when I received it and the inner tray was ripped as if it was previously used.
It's not bad as in it doesn't work at all, but I would imagine there would be degrees of badness. My system is a known good system. It boots fine. But it fails at playing BluRay and fails with playing my favourite game.
I spent £150, or more, just on trying to get BluRay working, and now I got problems with my games.
The Catalyst controllers also don't control the fan on my new card properly either, it's just permanently on. Obviously making me wonder further whether there's a fault.
I think your problem is outdated bios on your motherboard. You have done everything except update that.
If it were a bad video card, you would have seen graphical glitches and artifacts everywhere, and not just when trying to play blueray or HD content. But, It could also be the Manufacturer of HD4670 that could be to blame. I purchased a HD 3850 from VisionTek that was absolute garbage. I returned that card and got a Sapphire HD 4670 1gb DDR3, and it does everything flawlessly.
The reason behind suggesting the motherboard bios update, is because your motherboard is a little bit older and may not fully support PCI Express v2. The reason for bios updates is to fix issues the manufacturer has discovered through issues reported by their customers.
I'm confused a little, because it sounds like you never downloaded the latest drivers from ATI/AMD?
That should have been the first thing you did after installing the new card.
Sorry, I don't mean to sound critical, but if you are running outdated drivers (which most are by the time you pull the card out of the box), then you will be lucky if your card performs well at all.
Sorry I mean, I wasn't running updated system board chipset and BIOS drivers. They were from 2007 and 2006 respectively.
The graphics issues were present both on the ATI drivers that came out of the box with the graphics card and also in 8.12 of Catalyst. CCC refused to control the overclocking features of the card. Despite unlocking and setting values, no changes would occur and the GPU would remain at a frosty 39 degrees.
I swapped that card for a 9800GT and unlike the 4670, it reports the correct bus type in DirectX/3D Mark Vantage. It kind of makes me wonder.
I have just updated BIOS and Mainboard drivers. Done absolutely diddly squat for performance but there are a few more buttons to press now.
