Asrock N68 MoBo with PCI express 2.1

[maverick77_uk]

Hi all,

I was just wondering if anyone out there has a Asrock N68 (Am2/3) based motherboard running a modern Radeon graphics card (PCI-express 2.0 or 2.1), I guess like the 5xxx or 6xxx series. I only wonder because I have a N68-S3 UCC, which has a PCI-express x16 V1 slot, and I know some V1 slots have problems with V2 or 2.1 graphics cards, which I think is usually a BIOS issue. I'm generally thinking of maybe upgrading my graphics card to something like a 6670 or maybe 5770, and was just wanting to make sure it was likely to work!!

Cheers!

PCI-E should be backwards compatible, and seeing as no single GPU card surpasses the bandwidth of PCI-E 1.0 x16 (same as PCI-E 2.0 x8 if it helps you research) you shouldn't have any problems with lower end cards like those

It'll almost certainly work fine - I ran my pcie 2 4870 on an asrock skt 939 board which only had a PCIe v1 slot without any issues. But if you're not sure email Asrock - I did and they pulled an old motherboard out of their warehouse and literally checked it worked for me. Fantastic support for a product that was by then several years old already.

You wouldn't be interested in a 4870 instead by any chance mate?

I built a mate a PC a couple of years with a HD 4850 on an ASUS AM2 board with the same chipset, and it worked fine. Given the PCIe lanes all run from the chipset with AM2 boards, there's no reason ASRock's implementation shouldn't work!

Hi all,

Thanks for your replies!

Yeah, I know it *should* work, its just there is a fair few stories about people having compatibility issues between v1 slots and v2.1 (in particular) cards. It also seems particularly with AMD Radeons rather than Geforce cards. In theory they should all be backwards compatible, it was just in case someone by chance had that combination already and knew it would work.

Yeah, may email Asrock directly for a laugh!

Thanks for the offer Kalniel - don't think my PSU is up to it! Also with the ever-increasing cost of electricity (about to jump again in August for us), the lower-than-75w so bus powered 6670 seems to most appealing at the minute, even if its not the most powerful!

Cheers!
