So i used the CPU upgrade option on my motherboard and i have 4.7Ghz stable on my 4770K. how ever its just the CPU core speed that's is clocked.

When i bump the un-core speed, is it the ring voltage that needs to be bumped too?
What should the MAX voltage on un-core be?
Also what other options should i be changing.


I have dropped the clock to a nice 4.5Ghz @ 1.221v for day to day use.
What i run Cpuz stress, cinebench R15, and firestrike at the same time i get a max temp of 67c.
Cpu is OcUK de-lidded, and under custom water
 
Yes its the ring voltage for the uncore mate. Tbh im on 4.7 with my 5960X but only have the uncore set to 38 because I have a non OC socket board. I'm not certain what the max ring voltage is on your board with that cpu but I have my ring voltage on 1.25v
 
i shall be having a play now. would you say 1.25 would be max sort of day to day voltage for ring? i found some info saying 1.35 was max on air?
 
I have mine running at 1:1 with the cpu so both at 4.4Ghz. I need 1.30v ring voltage and 1.90v cpu input voltage for that. Apart from vcore and dram voltage I haven't touched any other voltages in the bios.
 
i was told to not push un-core too much because it only as a real impact on benches, and the extra volts make extra heat.

right now i have
Core 4.5 @ 1.221v
uncore 4.1 @ 1.22
all other setting are at unto.

playing BF4 on large scale battles i get a max temp of 66c so i am very happy and will let it run at that.
I did some testing with LinX and hit 79c but that is a unreal amount of stress.

Like you say, you probably can't tell any difference but mine runs at that speed so that's what it runs at. Heat's never been a problem with my setup. During gaming the cpu is in the mid-high 30's depending on the game and even with IBT I am only hitting the mid 40's at the moment (mid 50's in summer). That's the joy of having a pair of rads mounted in a box on a windowsill sucking cold air through them plus the cpu has been delidded, CLU applied and the IHS stuck back on after being lapped.

if IBT is only pushing to the 40's on the cpu then your not doing something right. it would go higher at stock speeds. unless you have sub ambient cooling.
i have 2 x EK we 540's strapped to the bottom of my desk and i would get higher that you get on stock speed gaming never mind stress testing.

i am assuming you have gone into setting and told it to use all cores?
 
Read my last post, the bit about the rads. My water temps at the moment are 16.2 degrees inlet, 17.3 degrees outlet. Yesterday it was 14.7 degrees inlet, 15.6 degrees outlet. During previous winters I have been down to single figures and no I don't get any condensation. :D:D:D

***Edit*** It was a older version of IBT I was using so I just downloaded the latest version of IBT and am no longer in the mid 40's. Still only 55-57 degrees though. :D:D:D

And lapped. The IHS was horribly concave. Worst one I have ever had. Still didn't make any difference to even the cores out though. That core 4 is really bugging me.
 
This is mine at stock speeds hitting 71c, am going to have my block off this weekend and reset it

Just take your time and it should be ok. It's probably the most nervous thing I have ever done with a pc component, even worse than my first ever water loop many years ago. If you have a gap between the IHS and pcb it's well worth trying the floss method.
 
Op states that his chip is already delidded. P4clock, did you use liquid metal paste on the bare die? A conventional paste like MX4 etc doesnt achieve the same temp drops as liquid metal. I know that ocuk did sell 4770k's that where delidded and pasted with liquid metal, but theese could only be purchased as a board, cpu and ram bundle.

no i didnt use liquid metal. when i went to delid the cpu i found it have liquid metal there already and if i had known this i wouldn't have touched it. i used to run my 4670k without the IHS and that was the plan with this but i think it will need liquid metal and the IHS refitting.

I have jkust removed the water block and tested the cpu with a stock cooler and i am getting the same sort of temps at stock speeds so i think i may have air in my loop and not seated the block right.

I am half way into building an x99 system so i may part out this and finish that off.
 
I remember now, you bought the cpu from OCUK and everyone thought it had been pre-used. It wouldn't surprise me if it had been returned looking at those temps.

Mine actually runs hotter with the IHS off for some reason which is why I stuck it back on after applying a fresh bit of liquid pro. It makes a big difference even compared to Gelid Extreme. I only have CLP between the IHS and the cpu die with Gelid Extreme between the IHS and block.

What block do you have and have you got the inlet and outlet the right way around?

Haven't you sold the cpu/mobo/ram now?

Yep just droped it on the MM and its gone lol. on payday al get the last 2 things for my x99 system.

the CPU block was an xspc raystorm. i have just before listing for sale refitted the IHS but not tested temps. i would think al still be around the 70's under load but thats fine for an overclock.
