I would like to ask the experts here something regarding pcie speeds.
So, for reasons I explained in another thread (and they are irrelevant to my question now, so please don't just tell me not to do it) I want to oc a non k intel via bclk speed (just to max 105 from 100mhz) but any speed above 101.4 will set the pcie slot from 3.0 to 2.0 (at least as reported by gpu-z even when stress testing with the built-in stress test.. is ist possible that gpu-z is wrong???). After lots of reading and seeing YouTube tests I know my gtx 1070 is at the border of saturating the pcie 2.0 x16 bandwidth( some games won't bottleneck at all, but some with up to 10 fps loss which would negate the gains I will get from oc-ing my 4770 ).
The strange thing is, I made a test with the hardest gpu benchmark I know of: the Superposition at ultra with PCIE 3.0 and then 2.0, each with stock and then with +79 mhz on core and memory.
(Note, I got the pcie 2.0 by getting just minimally above the 101.4 bclk threshold to 101.6, so that the minimaly higher cpu frequency wont have any influence on the scores.. But cpu usage during this benchmark is max 10% anyway so that's not important).
So the worst result was the pcie 3.0 with no gpu oc
Next was the pcie 2.0 with no gpu oc (but with oc pcie thanks to the blck)
Second to best was pcie 3.0 with gpu oc and the highest score was the 2.0 with gpu oc.
The fact that while in pcie 2.0 oc gpu test got the highest score makes me think that the bios may want to limit the pcie to 2.0 but because of the bus overclock the data is beeing transfered more rapidly and because the HARDWARE itself can manage faster data transfers (pcie 3.0) there is no real hardware limitation happening. Is this true?
Also, can running this 5Mhz blck oc damage the pcie slot or the graphics card in the long run? I didn't see any negative effects while testing for 10 minutes but is 24/7 operation safe?
Also what is regarded as a "very high" blck oc? There are some voltage calibration settings in my ROG bios for when using "very high blck" which can improve oc/performance. Should I enable them or is my 105 blck not "very high"?
