Long Long process short story: I have been having some problems with my 9900k, with Overclocking (first timer) and temps (240mm AIO).
I want to make a first time custom loop sometime in the next few months, potentially.
But I need help with my current cooling solution, the overclock, and the potential of returning the parts tomorrow; as it is the last day I can go in and RMA both the CPU and MOBO for direct replacements or store credit.
1st.) Prime 95 has killed any OC I have thrown at it, aside from like 1.1v @4.6ghz with temps at like 99 throttling.
2nd.) Ive gotten 4.9ghz & 5.0 ghz stable, but at 1.2v @4.8ghz Ive gotten the only temp range that I am wanting to stick to. Here are those results from my reddit post:
1.2v @ 4.8ghz - AVX offset @3 - LLC @5 - 45 Cache - XMP 1 - VCCIO @1v - System Agent @1.1v. Im running stable on real bench 83/84 degree temps - Aida64 full load with AVX on im sitting at about 80/81(ie: 4.5ghz because of offset) and without AVX on im sitting at 79/80 (Full 4.8ghz). FPU only hitting a max of 93 but settled to 91. Cinebench capping out at 83-84.
3rd.) A lot of the feedback I have received so far is that the issue is potentially the cooler? But I think its the chip maybe, i dont know. The cooler seems to be working fine. I just recently upgraded from a 6700k, which yes I know the 9900k is a completely different beast with thermal monstrosity, but the cooler I know is working fine. Yet, I've started to doubt that with all the outside thoughts on it.
4th.) The reason I think it is the chip is that now, turning my OC off with just XMP on I am getting ridiculous temps. Cinebench is spooling up to 91-93. CPUZ is telling me voltage is at 1.234v (after the .05 v droop I think I have), this is with the cpu staying at 4.7 ghz. 15 seconds into Aida is sending me to the upper 90 degrees & 1.288-1.305v (auto LLC is going to 2). And then it drops down to 4.1ghz to keep temps at the 70 degree @ 1.1v after droop. (This is with everything set to Auto, but Asus multicore Disabled. Enabled yielded a few more degrees)(XMP set to auto keeps cinebench temps down to 88) Do I just have something really wrong in the bios with the OC turned off that I'm not realizing?
I have gotten the best results temp wise from my 4.8ghz OC. 4.7 Was a little lower as well, but 4.8 yielded temps that were acceptable. I am getting the lowest boot temps, stress test temps, everything with the 4.8 OC.
What do I do? I am willing to work with the OC all night, but I do need to decide what to do. The chip itself seems decent on an OC standpoint. I got 5ghz running at I think 1.28v. Temps were just 10 degrees or so higher than 4.8ghz.
Also it looks like my idea Vdroop is about .046 ( 1.2v in bios, 1.154 under load) (LLC @ 5).
Ask away I'll be very responsive so I can hopefully get some insight on what to do!
