    This new CPU works great. Folks at SL did very well. Operates at 4.9 with no problems. Thermals much improved from the 7900 with -2 cores. Doesn't seem to require any tweaking on the Uncore voltage so far. Highly recommended.

    Hows that chip doing? Im in the middle of installing everything in a new case with a new 9940X. Ran it on a box top for a few days getting it all configured and got 4.6 very easy and ran a few rounds of real bench at 4.7 before shutting it down to get it in the case with some decent cooling.
    Do you know "G.Skill F4-3600C16D Trident Z RGB Led DDR4 3600Mhz CL16" sticks should run on what voltage on XMP ?

    Thermals with my 9800 seem much better than with my 7900. I’m curious how the 9900x will do. Give us an update. Thanks.

    Well 2 bummer chips. First took 1.235 for 4.6 and would never hit 4.7 even at 1.26. Second one can’t hit 4.6 even up to 1.25. 1.25 is about the cooling threshold where my 360 aio can’t keep it cool under full load. Using the stats from silicon lotteries 7900x results I either go unlucky or these are just harder to oc. Gonna return the second one. At this point I wish I kept the 4.6 one.*

    Yeah thatís the tough part, especially if you put it in a custom loop. All the work involved at replacing. I fired up my 9940X with my box top cooling loop being an EKWB xres 140 with a D5 pump on a 280 rad with just plain case fans and an EK monoblock. Hit 4.6 pitifully easily then after an 15 min loop of realbench notes the cores didnít go back to where they were at idle......DOH! Plug in the fans you idiot!! When I bought the chip I told myself Iíd be happy with 4.5 on all cores and got 4.6 with no fans runningís and highest core at 80C. 1.215Vcore, didnít try lower as this was just a quickie before commencing the rebuild. I also noted the monoblock not making contact with the entire IHS, just a circle in the middle leaving 30% uncovered. I checked the chip architecture and the hottest cores are in the corners. Off with the monoblock and installing a heatkiller pro IV and also their VRM block. Iím confident Iíll get 4.7 if not 4.8 with the rebuild having enough in rads to cool a nuclear reactor! 2x 480s with push pull, a 360 and a 280 with push

    Which chip did you get? 9900X? If I remember correct the stats on the 7900X were less than 10% getting to 4.8 or higher which is where mines been running for a year with the occasional bump up to 5.0 for fun and a few benchmarks as that was just too hot even delidded but now Iím questioning if that monoblock held that back.*

    ya got the 9900x. ill be ordering my third tomorrow. i want 4.7 or a chip that can do 4.6 with similar voltage as you. i see no reason to settle and even the smallest .01 jumps in voltage is really reflected in temps. not to mention i need almost 2 volts of input to stay stable.

    Thanks for the update. If you donít need the extra cores, get the 9800. Well worth it to me.

    So you drop 2 cores for more Mhz? seems like a waste of cash to me, just disable two cores on the 7900x and delid it and overclock it to 4.9.

    I wouldnít know how to disable 2 cores. Interesting. Thanks. *
