This was moved to general hardware when it is a SPECIFIC question about the Z97 Classified not seeing my Gen 2 pcie card as Gen 2 but reporting it as Gen 1. The questions was as follows. XFX Radeon HD 5870 XXX 1GB 256-Bit DDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity OK SO I see this and I have always thought these cards were Pcie Gen 2 Mine shows here ( ON THE Z97 CLASSIFIED) as Gen 1 by default. Am I wrong or do I set it by force to Gen 2? Also how much am I missing out on if it is being used as Gen one VS Gen 2? Thank you for any info.

Hi Nick, on my motherboard I had to force GEN3 for my GTX780 Ti. So if I were you I would force GEN2/GEN3 (I think GEN3 is backwards compatible, but I'm not 100% certain) and load up GPU-Z to check. On my gigabyte, the PCI-E GEN settings were set to auto by default, yet it did not switch to GEN3 for my 780, I had to manually set it. Test it out, let me know what happens, I would go with GEN3 first and see if it works. Good luck! Note: As for the differences in generation, assuming we're talking about a x16 lane slot, each direction: Gen v1.x: 4 GB/s bandwidth (40 GT/s raw bit rate), Gen v2.x: 8 GB/s bandwidth (80 GT/s raw bit rate) and Gen v3.0: 15.75 GB/s bandwidth (128 GT/s raw bit rate). Now hypothetically speaking, if your card is only using 3.8 GB/s in bandwidth, using GEN2 will not improve anything. However, if your card can use 6 GB/s of bandwidth but GEN1 is limiting it to 4 GB/s, switching it to GEN2 would allow the card to fully use the 6 GB/s of bandwidth, so having it set to GEN1 is actually limiting the performance. I don't know what bandwidth your card uses, how high it can go, these numbers are just as an example. Hope this helps! Edit: GEN3 is fully backwards compatible, you can read more here (question #6). I suggest setting it to GEN3.

ONE more thing. I set it to Gen 2 and 3 ( found out that the card is PCIe 2.1 ) but every time I reboot it still says in the upper right that it is GEN 1 X 16 Nick

Download CPU-Z and see what that is telling you in windows. Let me know here, I'll research while you figure this one out.

Should look like this.
When I look at the Bio screen it still says gen 1 but here is says 2.0 SO I guess it is working but I still don't get the Bios reading.

I think the slot is auto-switching but I'm not entirely sure. For instance, when I first boot my PC into windows, it'll show me 3.0 in GPU-Z, but if I leave it idle for a while it goes back down to 1.0. However, once I start a 3d application, it switches back to 3.0. So I think during boot, the slot is at 1.0. Anyways, it looks like you're all good now. Cheers!

That makes sense! Thank you very much! I wish Corsair helped as much with this pesky memory issue and I would be all good! I do love my new build though. Ram is now the choke point.

Just so you know nick... I have the same gen 1 issue in the bios. EVGA has acknowledged that it is a BIOS mis-reporting issue. Go by gpu-z... The cards down-clock when not being utilized so that is why you see it changing in gpu-z... judging from your gpu-z pic, it appears you are good to go. I don't know why EVGA didn't address this in the latest BIOS release... Maybe it will be addressed in the next BIOS update. You can read a thread I posted about this problem here... http://forums.evga.com/8x...t-16x16x-m2185490.aspx
