I just got done setting up my build consisting of parts from old computers/spare parts. I bought a new case, the Node 202 and a Asrock H97M-ITX/ac

CPU - G3258
GPU - Gainward GTX 660
PSU - Corsair SF450
Mobo - Asrock H97M-ITX/ac
Memory - 2x2xGB Corsair sticks 1600mhz
SSD - Toshiba 240GB
Case - Fractal Des. Node 202
OS - W10 64bit

The case comes with it's own 90 degree GPU riser due to its unique design, and is the only way I could fit a GPU in the case. The problem occurs when installing the GPU with this riser. Computer hangs and freezes until I am forced to hard reboot, occasionally it shows a BSOD but rarely. BSOD messages it has shown are driver "IRQL_not_less_or_eual" and "DPC_WATCHDOG_VIOLATION". I have tried taking the mobo out and connecting the GTX 660 right on the PCI and it works fine. However when using the riser it acts up. In the BIOS there is an option where I can manually choose PCI1 Link speed. either Auto, Gen1, Gen2, or Gen3 . When running through Gen1 or Gen2, everything is stable WITH the riser, as soon as I boot in AUTO or Gen3 with the riser it becomes unstable freezes, hangs, hard reebot. Note: with GPU coneccted directly to the motherboard with no riser PCI1 Link Speed runs just fine on AUTO.

Won't running through Gen 1 or Gen 2 limit the connection speed of my GPU? Running FurMark stress test with 1920x1080 preset only achieved a score of 1751.

GPU drivers are up to date, and UEFI v. 1.8

I don't get what the problem may be, GPU works, riser works..(just not in Gen3). I have seen other builds with much more powerful GPUs and same case not having this problem, so what gives? Would my GPU be limited by only running in PCIe1 Gen2?]]> Sat, 11 Jun 2016 21:29:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=2828&PID=14097&title=pcie1-link-speed-what-is-the-difference#14097
