I now have it running at 4.4GHz 1.3V Not prime stable yet (havent tested yet). I am actually thinking of doing a custom mount on the H100i waterblock. Just run some bolts through the mobo with the back plate, and clampo it down with some washers and nuts.. also applying some artic silver 5.. because then i really propperly clamp it down. without having to fluff about with them thing that dont handle a lot of stress on it before fucking up.. I did the same thing with my Q6600, and my storm waterblock. worked a treat.

4.2GHz was actually prime stable, untill i had to cut it short because the cpu got to hot, and now have had far cry 4 running for 4 hours 50/60% load on 4.4GHz dropped the voltage to 1.3V, i can probably get it lower but ill do that tomorrow since its frackin late now. I even let far cry 4 run at 4.2 overnight just to have the sort of get used to teh higher voltage and higher speed before bumping it up :P i wil find a sweet spot eventually..

Well i cant seem to get it above 4.0GHz 4.2/4.4 GHz up to 1.30 V And it just BSOD's as soon as i put any stress on it.. or immeadiatly.

So i cant be bothered any more right now, ill just run it with 40 Multi and adaptive voltage so it also volts down under light load, giving me slightly more power saving..

It does anything i want it to do, maybe ill look into skylake.

EDIT: Wauw i just played a whole 64 player round of BF4 on 4.2 GHz.. I took a slightly different route..

Vcore is at 1.32V , VCCin is at 1.9V , Cache/ring voltage is 1.2V , mutli of 42 , cache/ring Multi on 35 .. I set initial BLCK/DMI and BLCK/DMI bus manually to 100, instead of xmp i set memory speed/timings/voltage manually.

Ive been bussy again trying to get to 4.4 GHz and then 4.2 GHz i tried setting to 1.25V + 0.005 i triec ache voltages, PLL overvolt But for the love of all that holy i cannot get it above 4.0GHz.. I mean 1.25V.. thats a lot for a haswell ? innit ?

The temps are about 10 to 20 degree lower then before. And i have tried 4.4GHz with a 44 Multi and manually set for 1.24 V And i could play BF4 for about 5 to 10 minuts before it BSODed.. hmmm in the weekend ill have more time..

BTW i would actually prefer to have EIST on so it also clock the volts down again when im not using it that much. i watch YouTube on 800MHz and game on 4000MHz and thats the way i like it to be honnest.. so unless theres a major performance improvement, when setting volts to manual.. id prefer adaptive voltage..

Well i could remove the H100i Block, and re-apply with some AS5, but even if i set the volts to adaptive and set the multiplier for 42 for 4.2GHz it just gives me a BSOD..

EDIT: Well i just did some investigation, and turns out there was still some give on the screws holding down the block. So i cranked those down somewhat with teh help of some pliers, since i didnt have a propper screwdriver ready. And im getting much better temps now :D much ablidged horgen. i would never have suspected something wrong with the H100i otherwise..

Well whenever i run prime95, with the volts on auto it volts to about 1.225 And run 88/90 C wich is waaay to hot, if i set volts to 1.2 volt it just fucks up..

Ive got a 4670K and whenever i put 1.2V or over on my cpu it gets waaay to hot. that maxes me out at 4.0GHz.. am i missing something here. ive got a H100i with 2X 2K IPPC fans on it..

Well i wouldnt know, but what i do know is that, me personally i have no need for 4 titan x. Waste of money in general.. and by general i mean buying the cards/powersupply and powerbill and so on..

At least youre being fracking honnest fort a change, maybe if you werent such a duck about it :P So youre saying you got them cause you can, fair enough.....
