Hello,

So I finally got around to overclocking my brothers rig and my god does it do so well. Did 4.5ghz at 1.21vcore stable for 15m prime.
The problem is however that it jumps 15c sporadically during stressing.

Using a h80i with dual SP120s the cooling performance seems really good overall. The Water temps go up to 40 quickly during load and lowers really fast when we drop the load. This, to me, means that cpu -> cooler contact is good (water heating up properly), cooler -> radiator contact is good (water cooling down quickly) so the cooling should be good.

Idles at abouts 27-35c (so hard to tell with haswells spikyness), which is great for haswell imo, I idle higher myself.


Temps go up to 75-80c after about 5mins of prime, but then suddenly out of nowhere shoots up to 95 for 30s or something, then lowers down to 80ish. I mean, I spike 5-10c myself from time to time (probably the VRMs on die) but never to his extent.


This would not bother me if I wasnt stuck at a 1.21vcore max, 1.72VCCIN, 1.15uncore (AT FRIGGIN 4.4GHZ). Cheapo 1600mhz 2t memory went to 1866 cl9 1t instantly at 1.575v. Everything is litterally tearing itself another ***hole. I REALLY want to punish this to 1.35vcore for benching.
