Changed my Tim from MX4 to Gelid GC Extreme, pretty decent temp drop. CPU @ 4.8ghz 1.28v


Appears I have one slightly warm core and one thats noticably cooler, guessing it's probably due to the IHS compound variation. Also noticed the image and encoding score on the Gelid run is higher as it maintained the max OC instead of fluctuating so much.

You could probably get lower temps again by using liquid pro/ultra. Great stuff but hard to remove, it's the choice of paste for the die when delidding.

Yeah I have seen that stuff, I'm just not too keen as I regularly strip my loop down. Wasn't to see if I can get a decent 5ghz 24/7 just need the time to sit down and tinker.
 
Yeah dont use it if you strip it down a lot, i use AS5 untill im was happy it is gonna stay on for a while.
 
It is possible to remove liquid metal completely using an isopropyl jet wash. Sold my 4770k to another user on here who got it cleaned this way.
 
Had a couple of WHEA errors over the past 3 days, complete crashes.

I am led to believe that they are caused by under volting CPUs?

Is it worth me bumping up my voltage a tad?
 
Nah just playing BF4 then "Oops something went wrong. WHEA Code **********"

I'll bump the VCore up a touch, never had it before. Been using the Gigabyte OC utility and until now it has been spot on.
 
Clock is 4.7, not sure on Vcore off the top of my head, will report back around 4pm when I get home bud.
 
Hi guys,

I'm pretty new to overclocking (had a i5 2500k that I literally pressed the "gimmie more hertzz" button and boom), I got an i7 4790k, the mobo is a ASUS Gryphon Z97 Armor Edition (Micro ATX) and it's being cooled by a H100i. atm I get around 25c on idle (could probably get it cooler if I had some better fans).

Basically I was wanting to know where I start, what I should be trying to achieve when overclocking and any resources that can help explain it for an idiot such as myself, I've been told that I shouldn't use any auto tune features as that can cause problems so I shall avoid that.

Any help and advice would be really awesome. Thank you.

Ok here goes,

Clock is 47 across all 4 cores
VCore is 1.226V
VRin is 1.050V

Kinda missed this Josh, i reckon you definitely need a bump in vcore. As i mentioned above, WHEA errors particularly event id 19 can be vcore related. Also when putting up vcore, you need VRIN at very least 0.5 above the value of your vcore. In my case i require 1.300 on vcore, this equates to 1.800 on VRIN. Whatever you do, dont confuse VRIN with VRING on your board. On asus boards like mine, VRING is known as cache voltage, this is for clocking the cpu cache or uncore ive seen it labeled as. After the advice of sweagle in this thread, ive set mine manually to 1.2v and things are grand so far.
 
Got my new system up and running this afternoon, Asus M7F, 4790K, TG 2400 and a H100i.
Opened Cpu-z, chip runs idle [email protected] with temps under 20c.
Start up realbench(stress test), chips running [email protected] with temps mid 50s.
Only thing I changed in the bios was enabling XMP and nothing else.
Just ran realbench again, with Cpu-z in the background and core voltage remains the same, idle or load.
Can't understand why the voltage isn't dropping when idle. Any ideas?

Might have a stab at OC'ing this tomorrow afternoon.
 
Been playing around with it for the past few hours, but the core voltage does'nt drop when idling.
Power option set as balanced. Intel speedstep enabled, as is C1 state.
Bios settings I've changed are XMP enabled and set core voltage, everything else is unchanged.
As I said earlier, the voltages dropped when I first ran realbench on the default settings. I know it's not Cpuz, as I have tried a couple of versions and it's the same on HWmonitor.
 
On fixed voltage mine doesn't drop down either, balanced power plan though ill need to double check c states. On this board if left in auto they're disabled.
