Quick questions about delid if you do not mind. Have you re-sealed your IHS? If so how do you know how much silicone to use not to have it too high or too low? Also have you left gap in silicone for air?

Finally, to everybody who may know. Am I right that CPU + its PCB on skylake is not conductive? I mean nothing there can be shortened really by CLU splatter. The only danger is that CLU would get into the socket?

My plan is to delid, put loads of CLU, I mean loads and then reseal leaving no air gap so CLU is not dangerous to socket.

Skylake no longer has the resistors or whatever they were that were on haswell chips that you could slice into with the razor method. As long as the pcb is not scratched nothing can short as there is a coating over the CPU lanes.

As far as the amount of silicon. You use a toothpick and smear a small even layer around the point the IHS makes contact. You typically do not leave room for air or anything.

I would be very interested in the results of your experiment. Air being a natural insulator surrounds the die leaving the past of least resistance through the CLU and to the IHS. The problem with die shrinks is that when you go from a small die to IHS you increase what is known as the spreading resistance. Spreading resistance basically occurs when heat is pulled from a small source to a larger sink. By filling the entire IHS cavity with CLU you would increase the area of heat transfer of the die and quite possibly reduce the spreading resistance also. Theoretically IMO this should work. The amount of CLU needed however would cost a good bit more than it's worth to many though. If you didn't fill the entire cavity you would end up with hot spots in the CLU which once the temperature stabilizes would end up yielding the same results as not filling so making sure all air is out is crucial.

If I was to do this I would flip over the IHS and fill it to the brim with CLU then line the edges of the PCB with silicon and place it together while the IHS was still upside down.

In reality though all this would do is add the edges of the die as heat transfer area. The magnitude of the heat transfer of the walls in relation to the top die is usually neglected due to it being very small in proportion. If I had to venture a guess all this work might yield another 2 degrees reduction at best.

Sorry for the long winded response I was kind of talking my self through the experiments as I was writing wink.gif

So i changed my LLC level to 5.
Disabled Intel Speedstep
Cpu core/cache limit to 255.5
Cpu min and max cache to 41
Voltage on manual 1.3

I almost have no vdroop, and i'm stable at 4.5ghz.

Now i just have to change from manual do adpative mode, right?

From memory, when I delidded my 6700K I did note some gold contacts on the top of the substrate. Not sure if these are manfacture test points etc but I would be careful in not shorting these out.

as posted above...

Yes I resealed the IHS using Hi Temp silicon (loctite 587 blue) - a thin thread off a toothpick works fine. I remove lids with hammer and vise. Always leave a gap if the IHS does not have a breather hole. I suppose that if one were to goober up the CLU/CLP application something could go awry... just use a paint-thin layer.

Could someone give me some tips on how to OC by changing BCLK instead of just the clock multiplier?

I'm wondering what settings I need to look at aside from BCLK and what to put in them.

I'm using XMP profile for my RAM but I'm not sure if I should be doing that since changing the bclk will make the RAM run even faster than already 3000mhz via XMP

Rig is in my sig,

Thanks.

Did my de-lid and re-paste.

Used Thermal Grizzly Conductonaut on the die, Thermal Grizzly Kryonaut between the IHS and waterblock.

4700MHz, 1.36VCore. Ambient ~74°F.

Did a quick run of IBT at maximum setting; only hit 63°C. Before the de-lid, I was hitting the mid-80°C.

Need to do a little tweaking and post a stress teat run result later.

Can you post you c-state settings in BIOS? My CPU drops only to 0.7v not to ~0.01v as on your screens.

Cheers
