I got a bsod when I tried 42 and vcore 1.111. It did boot though but crashed on intel burn test. It also reported to be running at max speed and not dropping which was odd when idling.
Should I have the 4 pin atx plugged in as well? Not sure if that affects anything.

How long did you leave it for to idle? if theres a process going on in the background that can cause a delay.

I think you should try fiddling with the LLC control in the BIOS, set it to say Turbo.

That will help kill an Vdroop, so lets say you set 1.111, you then put the system underload, you get Vdroop so instead of 1.111 it maybe drop to say 1.08v.
 
P.S you don't need the 4pin ATX, I asked TeamAU and they said they have not seen any difference with it and these boys do serious overclocking.
 
Thanks Stulid. Had a quick go on Easytune this morning, multiplier at 42 and the vcore was at 1.162 I think. Passed burntest fine anyway so will take that as my starting point. Not enough hours in the day :(
 
I've got my 4770K running at 4.2 @ 1.15v, but when running Prime my hottest core gets to about 73ºC. I'm running a custom waterloop with a 240mm EK CoolStream XT rad. To me this seems like it's running very hot, any ideas why?

To get it running Prime (for 10 minutes) at 4.4GHz I need 1.25v (although does boot at 4.5GHz with 1.25v). However at 4.4GHz with 1.25v VCore my hottest core hits 93ºC. Considering people are hitting higher OCs and using higher VCore on air these temps seem really bad.

Have I just got a duff chip with a really bad heatspreader TIM mount or is it more likely it's something i'm doing?
While not very scientific if I hold my hand over the top of the case where the rad air is expelled it feels cool, so it doesn't seem like a cooling capacity issue, unless I'm over simplifying it.
 
your voltages are fine but the temps are hot,can only be poor paste/application under the ihs imo

it cant conduct the heat fast enough to the waterblock hence higher temps

It could be poor paste application on top of the IHS too...
Not really a fan of ICDiamond, seems too thick. I don't spread it out, but just seems thick.
I never know if I've used too much or too little. If I take the block off to check, then I'm back at square one and don't know if the next mount will be any better :(

Does anyone know if the EK naked IB mounting kit works with the EK Supreme HF block as well as the Supremacy?
 
try some mx4 and spread it really thinly with your finger,this is what I always do,then see what temps are like
 
Was thinking of re-applying with MX-3 (don't have MX-4, except what came with the block).

Might get one of those 20g tubes of mx-4, or the 20g tub of Gelid GC Extreme as I think that comes with a spreader.
 
Might leave that till the weekend. Gonna be a pain removing and re-attaching the block while it's attached.

In another massively scientific and accurate test I also touched the radiator and the tubing while running prime and despite my temps hitting 70ºC (running 4.2GHz @ 1.15v) both were barely even warm. So it seems like the heat isn't getting into the loop very well.
 
Tried the template on OC guide. Can get through intel burn test but some cores hit 100. this is at 4.5 with 1.350v. Anything higher will fail. I think I'd rather find a 'safe' 4.4

Can get stable 4.4 @ 1.222v, I may just stick with that as temps were around 70.

Currently testing 1.11v at 4.2ghz. Temps peaking at 57 and testing on aida64. Should I select to stress just CPU or FPU cache and system memory as well?
 
Ok so I have settled for this. I can get 4.5ghz stable at 1.3 and highest spike on aida64 I have seen is 86 after an hour. This is simply changing vcore and freq, nothing else.

4.4 at 1.25 doesn't peak more than 80 and even intel burn test keeps me below 90 just. I think this may be the best option for me

Ok that's an option. Prime is crashing within 5 minutes but aida will run an hour plus. Not sure what to do.

Ok so with a vcore of 1.3 and 4.4ghz I can be stable in prime for more than the usual 30s. I shall see how this fares. Max temp hit 89 so far so beginning to think maybe 4.4 is my limit.

Sounds like we have vary similar chips.
I'm really considering delidding because of my temperatures (just very nervous about doing it).
 
Yes it does. I don't know why im even bothering as my system is fine for gaming as it is. I just always feel the need to squeeze it.
I will not go as far as delidding though. If I can get a few hours stable on Prime at 4.4 I'm happy with that.
