  1. Got a X299 dark lying around here which is waiting for 3 months to get a 10980XE depending on what price you have in mind for it. (also getting tired of waiting for EU to get any HEDT stock :( )

    Board is almost new only used in a review complete box included.

    yes, it does have waterblock included. in eur price would be 1750

    Sounds good, sadly still out of budget for me at this moment.

    When is the GOC final? Perhaps it's an idea to sell the other one after the cup? :P (if you would be willing to part with that one)

    I am going to try and help ( if possible ).

    Here is the most detailed procedure I FOLLOW when delidding . I always use der8auer's tools.

    So,

    1) Obviously the IHS is correctly removed.

    2) Remove all factory black silicon from the perimeter of the pcb.

    3) Clean everything very well with isopropyl alcohol. Wipe the die with soft cloth. Lap the inner part of the IHS with 320-800-1500 sand paper until the bronze appears and 

    mirror shine it.

    4) Apply a very small quantity of thermal Grizzly Kryonaut both on the die and IHS and apply evenly down to a very thin layer.

    5) Apply new high temp black gasket silicon on the perimeter of the IHS.

    6) Re-insert the cpu with the IHS correctly aligned on the pcb in the delid tool and use the curing pressure element of the tool to establish firm connection. DONT use extreme

    pressure.

    7) Let it cure for 24 hours.

    If nothing else is wrong, install the cpu and use carefully a thin layer of Thermal Grizzly condactonaut on the IHS.

    Apply your waterblock.

    Normally you are done. 

    Apprecciate the write out.

    Apart from the paste (liquid metal instead of standard tim), sanding on the inside of the IHS and the shorter cure time that is pretty much my procedure. (usually 3 hours for LGA1151 and letting it dry overnight for LGA2066)

    Isn't the first delid either my guess would be this is the 15th or something for LGA2066 and the only guy that had wierd temps was pumping 1,35Vcore through an 18 core paired with an AIO :P (Usually 15-20 degrees drop is what they reach easy compared to pre-delid)

    For reference the other delid with this copper IHS on a 7920X did about 65 degrees tops in prime with +- 1,3Vcore in a normal sized custom loop. (1x360 iirc)

    So yeah currently most parts have been checked and double checked.

    Hopefully we can get a nice imprint of the die itself to check if the shape is that much off the standard. Hell at this point it may just be a faulty tube of conductonaut considering i'm running out of other ideas of what it could be.  :(

     

    Wel it seems an update is in order.:

    After testing by rsnubje under the custom loop temps were actually good/okay ? (Based on 5x R15 loop, picture in OP was just a single run)

    After delid 4,7Ghz 1,25Vcore: 4700-5x_CB15-afterdelid.png

    Hell it can even do 4,8 on 1,3Vcore now :4800-CB15v2.png

    Middle of die is high AF the stock IHS should accommodate this. I doubt the aftermarket IHS you purchased accounted for this. The intel IHS is concave inside to match the convex die. Some cores will also always be warmer than others as some are near warmer parts of the die IMC/FVR/ etc. I suppose removing the left over silicone on the pcb is not an option for you? def helps. It is es might as well lap the die even some 2000 grit for 50-100 strokes should be a benefit. 

    Aftermarket IHS is actually the better one temp wise. Atleast with that one it is able to run at the volts/clocks.

    Ironicly the other 2 chips I fitted with the same IHS ran allot cooler so naturally I was checking this IHS if it were perhaps a production fluke. So far seems like that isn't the case.

    Stock IHS+ liquid metal and stock IHS + MX2 (only stuff I had laying around here) both resultated in pre-emptive shutdowns due to temperatures being past 100C mid way in R15 with the same cooling setup.

    From the start pcb and IHS were both completely cleaned since without oldkit the best temps are achieved :D  (naturally reseal with minimal kit to fixate it not raise it)

    Hi,

    Although my problem is not so big as yours ( I had a serious issue with cores 2 and 12 ), the only solution I thought of was to go to bios, select per core adjustment and

    lower the multiplier ( and voltage ) of these two cores by 1 step. Meaning, running 16 cores at 48X with 1.26V and the two "problematic" cores at 47X with 1.22V. This ironed

    out the big fluctuations at a +/- 5c under load status.

    The big question is though , is/was your chip also an ES or is it a retail sample?

    Also checking in here since i'm the delid guy in question here. No abnormalities on the pcb/die and coverage/contact with the die/IHS was spot on.

    So yeah been driving me crazy this week annoying chip this be :P

    Only other thing that came to mind would be lapping the die a little but even for me that seems excessive and truly a last resort + owner of cpu must deem it neccesary.

    Bump, this week scores with ambient liquid

    So any ETA on those ambient details?

    Combo of Cinebench/XTU benchmark and prime95 1344k/1344k should help to show what to chips can do 24/7 as daily drivers ;)

    Probably with core pll voltage 0.900 ( Maximus X Apex ) and vcore 1.4 /1.425  with a very good watercooling

    Yeah was wondering that.

    Got a Apex X here and a X61 for testing purposes and even liquid metal/copper IHS if need be.

    Coler aio 3x120mm fan Raijintek and nothing special. Ambient temp.

    Was 24/25c.

    5.4 was to much harsh i don't like push too much without ln2.

     

    Fair enough is also understandable.

    Would you consider a 475 offer including EU shipping? Might actually be in need of a good watercooling cpu for a specific demostration.
