It seems a big problem... I’m getting mad replacing my CPU at this point.
Piero, what did you buy?
It seems some kind of a lottery for now...I' d like to buy one too for my 7900x max load temperature but it is gamble...
I bought a 9960x from eBay 1300€ but seller refunded me when he realized the price was too low, then I bought a delidded 7940x on liquid metal but there are issues with shipping and actually I don’t know what will happen (a PayPal refund I hope). Now this #0 core stuff, it’s getting me mad. Probably I should buy a 14/18 core as stated previously, or just wait to see intel prices smashed by new Ryzens? I’m pretty confused right now.
Ok then, I did it! I bought a 9980XE boxed / sealed for €1500
I'm planning to overclock it to let's say 5.0 GHz for a couple of cores and a light oc to the others. Any help from someone already skilled overclocking a 9980XE? I'd like to gain from standard Single Core performances.
Congrats! That's a good price for a really good CPU that will last you for a VERY long time.
Overclocking this CPU will definitely need a really good cooling solution, and I am not sure what you have right now.
I currently have a 360mm rad and a waterblock with a push/pull configuration loop just for the CPU, and in my case I can do 4.6GHz on ALL cores at max on load is ~82c-84c. I enabled thermal throttling just in case because the 9980XE has a TJunction temp of 84c, unlike the 7980XE which has a TJunction temp of 94c. The 9980XE is soldered and 7980XE is not out of factory.
If you look at this post, I was able to get this score and could run it daily without issues, the CPU barely ever hitting 84c on load. The RAM has to be fast, though, that helps single core and multi-core performance. 64GB @ 3600 will be possible, but 128GB @ 3600 will not, from my recent experience. I was able to run 128GB @ 3466 (but with errors in memtest) but I wanted to avoid any type of errors in general, but if you dont need 128GB, 64GB @ 3600 is possible with zero issues.
I currently clocked all cores down x41 because I don't need that much horsepower right now, but can always bring it back up. I want to have a silent machine and now it just tops at 65c at most with x41 ratio on all cores.
If you want to just OC just a few cores (maybe 4cores @ 4.5+ Ghz? and the rest at lower amounts), you won't have an issue and you probably won't need a exotic cooling solution and an AIO will do the job (I recommend a minimum of 280MM though, but 360mm would be nicer). 5.0Ghz even on a few cores will push so much heat, it might not be worth it, but it's a trial and error situation of course. I recommend you do all the benchmarking with Intel XTU and Prime 95 and adjust accordingly and look at the temperature in either CPU-Z or HWInfo and be careful not to pass 84c, this CPU is more fragile than the 7980XE. I personally enabled the thermal throttling setting in the BIOS just in case.
