just won TOTO and i bought the i7-4790k.


i combo with H100i GTX water cooler. the temp quiet high in my NZXT H440 casing lor..test it on intel burn test with no oc, temp still can reach 90c like 1sec and down to 58~61c back and repeat. is water cool pump work like that? cant get static temp stable at 60~70c during 100 work load??

1st time using water cooler.

Want to share my findings . Treat it as a reminder for those new to migrating new rig to Haswell or DC.
If you are using Haswell powered computers and having random restarts when the PC is in idle (suddenly pc turned off and on again) . Disable C6 save state in the BIOS.
The problem with Haswell and older PSU designs is that Haswell has tough load transient response requirements when its lowest-power sleep states are enabled. Your reboots/shutdowns at idle were likely due to your PSU not being able to cope with those. It is a fairly common problem and disabling C6 is usually all that is necessary to get around that without needing a new PSU.
Do note the older PSU designs in the explaination.

Most of the time will even blue screen that give X03b bluescreen codes.

I am using a year 2010 power supply. My remedy is change "Package C-States Support from Auto to C3.

Hello, can help me set up the bios below?
4770K batch L316B300
MSI gaming 7 z97

Simple Mode
CPU Ratio: 47
Enhanced Turbo: [auto]
SVID Communcation: [auto]
VCCIN voltage: [auto]
CPU Core voltage: [1.24]
CPU ring voltage: [auto]

only changed CPU Vcore and CPU Ratio in my bios,below the pictures of my bios, I need to change something?


Better choose Simple or Advanced?






I want to use 24/7 which is the best option to choose?



enable or disable something?

wow !! so fast !! how much does it cost ?? found any laggy issue when playing games ? or overheat ?

first time posting here

hi guys,

i just OCed my i7-4790k to 4.60Ghz @ 1.18V. so far tested on Intel Burn Test, stable.

soo, for 24/7 usage..what i need to change in my Asus Maximus Vii Hero for adaptive voltage? dont bother change? need some guide here..

thanks! please read senpai! hehe

Hi guys,



Will be heading to Computex under Intel this year.

(and be playing/ benching with Intel 5th gen and maybe Skylake)


Anything you wanna ask the Intel guys?

Anything specific you want me to investigate with the processors?

i set adaptive voltage to +0.003v..think ok..coz my default is 1.176v at 4.00

You can run 4.6GHz stable @ 1.18V? That's pretty good. I need about 1.24V at same speed, else video encoding/Prime95 will crash.

how u set the manual setting for prime95? need the value..mind to share? will try to test my oc

Gave up on the i7 5775c that i've waiting, ordered an i7 4790K, can't wait to OC it d, my target will be 4.5/4.6Ghz below 1.2v
just give me luck that I strike a CPU lottery, haha.
Guys, wondering if you guys overclock the base or the Turbo? If Turbo will only limit to 2 cores/ 1 core right?
Thanks in advance

80c while on high load game safe or not?

no problem, The CPU can handle higher than that

Oh ok

What's your core speed and voltage? on what kind of cooler?
Better to keep it lower for longevity of your CPU life

3570k, 4.0 ghz on stock voltage, stock cooler

Ivy bridge, and stock cooler!! no wonder so hot..
Just throw a CM 212, and you can do much better than that..
BTW, wrong topic bro, here's Ivy discussion thread https://forum.lowyat.net/topic/2314027

Eh sorry for the wrong topic
tq for the tips anyway

any1 tried to oc this on gigabyte ga-Z97m-d3h ?
