NOT HAPPY with the i7 4770

Agreed, it also has better cooling features so more OC can be achieved. :)

Im afraid Doomed theyre no cooler running at all than the 4770k, in my experience the two 4790k's ive used so far were much hotter than the 4770k i had under certain programs. Intel basically told a pork pie when they said they improved the TIM.

4790K is much much cooler than the two 4770K's I have used. Seems to be down to individual user experience, as many others report better temps and OC limit with 4790K.

Not what I've read:

Read this page: http://www.bit-tech.net/hardware/2014/06/19/intel-core-i7-4790k-devil-s-canyon-review/7

It probably cost Intel less to tweak the power delivery, use better thermal interface material and speed-bin some CPUs, than it would have done to make similar changes to what we saw moving from Sandy Bridge to Ivy Bridge

I had heard rumours before of Speed-binning and new TIM..

no the cooling you have to sort out yourself..... this CPU overheats because the thermal paste is badly applied, they've used cheap stuff too.

this CPU will easily O/C to 5.0, the proof is right there on Youtube
 
I will agree with setter here. My 4770K and 4790K at same frequency and volts got EXACT same temps to the degree on all 4 cores during stress testing.

Now my 4790 is an L3 batch, so it may be somewhat down to that and newer batches have the improved TIM - if that is the case, I am well ****ed off. Can't be bothered with hassle of swapping out again (past dsr limit anyway) and it clocks reasonably well anyway, but temps are identical so the magic new TIM can't exactly be that much more efficient if at all.

I think its hit and miss, but theres certainly been higher clocks achieved (overall) on DC than there has on vanilla Haswell. :)
 
Ive had an L3 and now the current one in sig is an L4. Both got to the mid 90's using p95 ver 28.5 at stock speed. The first chip came with a stock vid of 1.264v, even when lowering voltage to 1.200 it still got into the high 80's. Second one has a vid of 1.200. My 4770k got to the high 70's at stock running an earlier version of p95. 94c max at 4.5ghz on 1.264v. At computex, 8 Pack stated on here that a few extreme benchers delidded some 4790k's and found no difference in the TIM.

yes maybe but it's worth trying, you have to extremely careful how you delid it, it sais so in the video, because the moment you put on too much paste it wont work..

the cooler to cpu is sensative too, it mustn't leak out the side....mind you, if it leaks out of the side you're in big trouble anyway, because then it gets into the Socket housing!!!!...........i did this 4 years ago, i lost both the Motherboard and the CPU ( AMD back then)

The black glue is what Intel use to hold the ihs on. You can leave it in place but it does leave the ihs sitting further away from the die.
 
I'll have to find the link later, but someone from anandtech did a test to see if it was the thermal paste or something else causing the heat issues. What he did is he measured how thick the adhesive used to secure the IHS was (0.6mm). He then delidded the CPU and applied some thermal paste to the die, and put the IHS back on. What he did differently than most, was that he put a 0.6mm slip of paper where the adhesive used to be, keeping the gap between the die and IHS the same. He also 2 other tests, one with the IHS not having been removed, and one with the thermal paste, but the gap removed.

The stock IHS managed 65C. The thermal paste with the gap put back in averaged about 68C. The thermal paste with the gap removed averaged about 50C.

The issue isn't the paste Intel uses, it's the gap that the IHS adhesive creates (film thickness) between the lid and the board

i saw the above on another forum..... very interesting :cool:

it's probably poor compound combined with the film thickness

solution:- put the lid back on without the glue and apply the glue carefully around the outside only

no because you have to clean it all off, but you could use Silicone sealent .....Araldite will be too permanent and tough, you've got to use something that will allow you to remove the lid again if you've messed it up.

you might find that it wont go above 4.5 anyway, but at least it'll be much cooler, because i've read that it doesn't always work
 
cheers that's great..... how did you protect the line of resistors, because in one of the vids i saw, the guy covered them over with the black glue ? :confused:
 
Stick some non conductive paste over the resistors, something like mx4 will do grand. Regarding the glue, a few guys i play games with on here bought bundles from ocuk last year. Theese were cherry picked 4770k's capable of a minimum of 4.6ghz. Theese were delidded and the lid stuck back on with the intel glue. Temps were fine in all cases. Much lower than a standard 4770k.
