haha...yalo...seldom touch pc hardware since the c2d used by my dad. rarely play around my bro's i2500k too but i believe still can go further more.
used my laptop for 7 years+ since uni until before I changed to this i5 haswell...beh tahan it always lag and bluescreen

anyone oc haswell with 125 bclk instead of 100? with same cpu freq, higher bclk required lower vcore?

4.6G @ 1.376v (bios set 1.36v)... weird, same ram freq & timing required 1.575vdimm to prime for 4.5g stable, however need 1.65vdimm for 4.6g...why huh?

yes, i use 1344k, 85% of mem used for testing

btw, if stressing with prim95 and restart without bsod, normally is due to insufficient of what voltage?

the chance of heat issue is small, since my cpu temp. never exceed 80degC under prim95 stressing

are u using vengeance pro 1866cl9 2x8gb kit? 2200 @ 10-10-10-27 prime stable?
I cannot get my ram stable anything above 2133...mind to share your setting?

use manual mode and enable c-state

off day and nothing to do at home, so I decide to replace the thermal paste in between IHS and HSF from CLU to IC7...at the same time, swap my ram to black slot and checking the ram version

looks like no significant different between CLU and IC7, but one thing that I noticed when I removed the HSF, either my IHS or HSF no flat enough, got a concave as the CLU is not really touch at the center area...

CLU


IC7


btw, my corsair vengeance pro 1866cl9 is rev5.29... and according to the corsair ram ic, they are hynix based ic...any comment?

nope, in between die and IHS still CLU... I believe temperature will become worse if change to other thermal paste

those timing is 1T or 2T? currently i'm able to run 2133 @ 9-11-10-27, 1T 1.65v

2400 9-11-10? dont think my ram can do...cant even boot at 2400 cl10
btw, does Hynix ic like high voltage? whats the typical voltage?

Just run hyperpi for fun and the first time, 4.6GHz, 1066 @ 9-11-10-27, 1T

Maximus VI Hero rm 830

bro, where you order 4790k?

bro, you need to delid it

@cstkl1

I have the 4790k same batch with you. How to check the default VID?



CPU = 4.5ghz@1.23v (vdroop 1.248v), CACHE = 4.1ghz@1.2v (vdroop 1.217v)

1.047v vid shown in BIOS... is it lower mean better oc?
VRIN/VCCIN = cpu input voltage on maximus board?

manage to get same 4.5g prime stable with lower vcore, 1.22v (vdroop 1.32v during load), same cpu uncore.



DC 4790k is oc better than my previous 4670k. but frankly, the temperature still not good although with the improved version of TIM... might going to delid soon

thanks cstkl1 for your oc guide

now doing 4.5g @ 1.21v vid (1.216v & 1.232v vdroop), and temperature is improved alot after delid

btw, my 2x8gb corsair 1866 ram is based hynix MFR chipset, any advise on how to oc it better? cant get it with higher freq

average i7 4770k is doing 4.2-4.3g

some update
now manage to get same 4.5g prime stable with lower vcore, 1.195v with higher dram speed, 2133MHz @ 10-12-10-27, 1T, 1.525vdimm.
