Hey all, second post here, just posted a CPU question over on that forum, now for my GPU question.... I'm running dual EVGA GTX 1070 SC2 acx 3.0 with full coverage EKWB blocks cooled by a 240mm rad and a 360mm rad. Both cards stay extremely cool under full load while gaming and benchmarking. reaching a max of around 45c I am using PrecisionX for overclocking, and with power target, temp target, and voltage sliders all at max, the max stable OC i've been able to achieve is +85 gpu clock, and +468 memory. Now, I'm aware that this is already a very nice clock, with speeds maxing out around 2075mhz. However, as with most, I'd like to go higher if possible. I am aware of the power limitation of the pascal cards, and I have yet to perform the power shunt mod. The strange thing, is that when OCing, I NEVER see graphical glitches, everything just freezes if I go to high. I still get sound, but all video is frozen. No warning, just freezing, requiring a hard reboot. Is this normal behavior? I was under the impression that an OC would fail with graphical glitches before failing completely. It has been extremely difficult to find someone with my same experience online. I am wondering if I am hitting the limit of my PSU as I am running an old, power hungry, x58 board. My PSU is a 750w EVGA gold modular. Does this sound sane? Any help is appreciated from this wonderful forum. Thanks!

Hey all, first post here, happy to be here! So the long and short of it is. Can one just up voltage to try to get more OC until the chip is too hot? Is heat the main concern in chip death? Info below and my reasoning for asking CPU - Intel Xeon X5650 2.8Ghz OC'd to 4.5 w/ 21x multiplier and 215mhz BCLK at 1.4v stable 24/7 GPU - x2 EVGA GTX1070 SC2 acx 3.0 COOLING - Full custom loop with EKWB full coverage on GPU and EKWB supremacy EVO CPU block, with 1x 240mm rad and 1x 360mm rad MEMORY - 20Gb DDR3 Corsair Dominator System runs EXTREMELY cool, with CPU temps maxing out at 65c under full load on all cores/threads Now, my reason for asking. I've seen others running this same chip that are able to get the multiplier up to 24x, but mine seems to be stuck at 21x no matter what I do. I'd love to get the extra 3x multiplier, as that'd translate to a 5ghz overclock roughly. I do a lot of CAD, photogrammetry, and video editing that are all capable of maxing out load on all cores/threads, so I feel as though trying to squeeze the extra out is a worthwhile endeavor. I realize the Xeon is not made for overclocking, but with the 6 cores and 12 threads, it keeps pace with much more modern and expensive processors for much less. I paid $30 shipped for this specific chip. In addition to this, I have a GPU OC question that I will post over on the GPU forums if you are interested, that is related. Screenshot of CPU-z attached. Thanks in advance to this great forum!
