Just out of curiosity, how much variance in temps are you seeing across all the cores? I'm wondering if i need to redo my delidding.

I'd have to do some testing to be 100% sure, but it is probably around 5 C between the hottest and coldest. My Core 4 is the warmest. So lets say on a particular test it peaks at 72C, a few will be around 69-70C and then the rest are like 67-68. I haven't monitored closely enough to know how that scales at lower or higher temps, but that is the range that I recall seeing when doing some of my stability testing. Again I'd have to do some tests when I get back to the PC to be sure. I can do that for you later.

BTW, my test was successful at 1000% coverage and no errors. Not sure if it stacks with my earlier test but if so then it would be 1500% coverage on this memory speed/timings. I will consider that crash a one off. If it comes up again I will troubleshoot further but I can't reproduce and the computer hasn't shown any instability otherwise.

Still need to tweak the memory but its been challenging trying to get the most out of it. I will be doing more of that tuning later tonight and tomorrow. Hoping to get something in the 4000mhz range with timings in the 17s but not clear if I can get that stable. May have to go looser on timings to get it stable but can't go too far or it'll be slower than my 3600mhz @ 16 with tighter secondary timings.
Okay yeah I’ve got the 32 3600C15QGTZR kit, I can get 3800 with CL16-16-16-36-374 at 1.38v, I can’t seem to get to 4000 and have all my sticks be recognized, I can get 2 sticks at CL17-17-17-39-630 1.4v but that’s it.

which kit is that? And which board are you using?

The difference between my hottest and coldest core are 10'C... Re-did the delid and removed the glue on the PCB (almost all of it. Left the outer edges so it looks like it is untouched)
Same results..



Hottest core was 76'C, coldest was 65'C.

Rest was around 69-72'C.

I am going crazy. I just tried one round of CB R15 at like 1.360V and turned off the machine.

The machine won't turn off, it just restart itself, so I had to use the power button.

I've never delidded myself but from the videos/tutorials I've watched online but when LM pools up like that it is too much LM. It should be a very thin layer brushed on the die.

1.360v sounds pretty high for a 7820x unless you really need it. What are your clocks at?

I delidded mine and yes that is too much lm, maybe just need to sponge some of that off. I did not reglue my ihs back down. Got about an 5delta out of that.

I wouldn’t go above 1.3v for daily use, and ideally not above 1.25. I’ve ran as high as 1.40v for 5.2 to bench something but immediately bring it down.

ah.. yeah, your original post had 3600c15 as a 32GB kit... unfortunately there's not a kit like that. Going off the reservation, I did mix 2 3600c15 2x8GB kits on this APEX. Took some tweaking to get to 4000c16-17-16-38-1T.

This is just for benching, besides the chip sucks OCing wise.. Needs around that for 4900mhz... frown.gif

Yeah, too much LM. I removed the pools before I installed it. So no worries.
