I received a feedback from an user that had some stuttering at regular interval (every two seconds) in any OpenGL application (including GLSL Hacker), on both Windows and Linux. Here are the main parts of his setup:
- ASROCK Fatal1ty X99M Killer
- EVGA GeForce GTX Titan X
After some discussions and tests, we find that the root of all problems was the BIOS of the motherboard. The latest BIOS for the Fatal1ty X99M Killer (v1.9) improves PCIE card and DRAM compatibility.
We have replaced the GTX Titan X by an old GeForce GTX 280 and all OpenGL demos and apps worked flawlessly. It looks like that with the default BIOS, the Fatal1ty X99M Killer can not handle big GPUs. Fortunately for Fatal1ty X99M Killer owners, ASRock has released a new BIOS that fixes this annoying issue. With the latest BIOS 1.9, all OpenGL applications work perfectly with the GTX Titan X.
I hope this quick post will save time of fellow OpenGL devs…
Thanks to the guys at 1024 for the picture of the Fatal1ty X99M Killer + GTX Titan X rig 😉
Say what you want, but even if there are problems with AsRock products, the support is fast and good.
I also once had problems with the graphics card. I had 3 monitors plugged into a Radeon HD 6970 and the BIOS would just halt and show up an error. I got a modified BIOS directly out of development (v2.25a -> latest you can download for the Fatal!ty P67 Performance is 2.20) which fixes the problem.
This is my major argument for AsRock.
