I7 haswell BCLK (base clock) overclocking is safe? How it works?
Hi guys, how far can I push the baseclock on Haswell i7 4790? I tried 105x40 on all cores, giving me a nice 4.2ghz for all cores instead of 3.8ghz but I heard it won't even boot on this setting - well it passed a short stress test, so it booted for me and working fine. Also it's still undervolted with -0.20v instead of -0.10 so it's cooler than stock. So I'm confused if I can make a 110x40 (4.4ghz) overclock with it. And also what will happen if it fails? Just BSOD and reset or something serious (just because I've heard that too, it will crash the whole system so I can't turn it on anymore).
And how does BCLK overclocking effect RAM? I see instead of 666mhz, it's on 699,7mhz and I don't know if it's good or bad or what it means.
Also I noticed in passmark that intel HD graphics could beat 2 stock comparable GPUs in all tests instead of 1, also it became number one in all 2d graphics test. So this looks promising, I didn't know this will affect the iGPU too.
System specs are in the system specs.
