I remember one guy writing, he can get his CPU stable at 4.7ghz if he turns off HT, but it's 4.5ghz at most with HT on, no way to get the BSODs etc. fixed at more than that
Hey, that was me. It was awful gigabyte bios, i think. F6 seems to work.
Belial's running 4.75 on ~1.44vcore and i should be able to do it quite a ways below 1.4*, but i'm not delidded atm. His chip's not great, just some brute force with delid and pushpushpullpull h110. I've yet to be convinced that haswell is any worse in terms of clocks than ivy, if you can handle the heat. It's ridiculous to judge an overclock on avx2 synthetics temperatures, because they'll run you over 90c on stock settings with a silver arrow, stuff like chaining cinebench runs or using x264 as a stress test give you temps that are more in the expected range and not the cpu-socket-filled-with-lava type stuff people complain about. The gap between real, full cpu loads like x264 or cinebench and synethics that abuse AVX is massive with haswell, much much bigger than previous CPU's, and it scares a lot of people off, or makes them call the chips hot/bad which is just confusing and wrong IMO. Try it yourself, i did. 3.4ghz manual, no turbo and 1v vcore with avx2 runs hotter than 4.5ghz, 1.2v running with either AVX disabled, or in something that runs a load that is not primarily avx, like cinebench/x264 as opposed to linpack.
*got 4.625 on 125mhz strap @1.25v or so.. one multi won't cost me 0.15, not even close, i played around 4.7, 4.8, 4.9 before and even when i had crazy instability i could make them work for quick passes of pretty much anything, they just had a habit of falling face first off a cliff when put under extended loads or some weird stuff like 4.7 which passed 14 hours of prime and then failed in 12 seconds with x264Edited by Cyro999 - 7/24/13 at 12:19pm
