any one tested this yet with pci-e 3.0 with 337.50? when i set bclk to 115 with pci-e 2.0 and play the BF4 and Farcry3 with no issues but aslong i set it to pci-e 3.0 mode, frame rate drops to hell and games start stutter. when i switch it back to pci-e 2.0 all works fine. card works fine with 100 bclk @ pci-e 3.0.
Yes 100 is default, so is custom 125 and 166mhz, that 115 is not. How did you manage to get that 115mhz, did you downclocked from 125mhz?
Why not just leave it at 100Mhz, last I read changing the BLCK on Sandy Bridge & Haswell gives very little performance increase.
Yeah leave it at 100. You aint getting any performance from going over that, certainly not on your GPU. I have issues even going to 100.5.
Overclocking bclk can cause much more issues on this generation of intel chipsets. You may end up with defective data from/to sata controller which will decrease reading performance and in some cases will lead to data corruption. You may have troubles with on-board lan as that usually uses CPU and system memory as cache.
