If thats on idle, you've got a problem with your WC seating, there was some guy not long ago with a problem very much like yours except that his block didnt touched the cpu heatsink AT ALL, thats not your cause or you would have a PC shutdown the moment you start rendering. Very low 30's degrees C (28 to 32c) is what you should be getting. It would be interesting to know what your idle temps are as that is also a good indicator of whether the AIO is on properly. Secondly you can lower the vcore for the 4.8GHz all core overclock to under 1.3v unless you are very unlucky.I have a Gigabyte motherboard and do not know which ASUS motherboard you have but there are a lot of good articles on overclocking the 8700K on ASUS motherboards and youtube should have some. I think you should look at reseating your AIO as it might not be on perfectly as I would except better temps than you are getting. at 4.8GHz I used 1.278v max on adaptive/offset mode and my temps before delidding were for gaming around mid 50's and for Cinebench mid 70's degrees. Hi, I think a couple of things come to mind as I have pretty much the same setup. Sry but the 8th gen isnt my field of expertize, but here's what you can try instead, since you can run 4.8 1.3v, then reduce it to 1.290V, test, reduce again to 1.280V test, until it fails to boot or becomes unstable, thats how you might find your minimum VCORE for 4.8ghz, wich will result in lower temps. Notice that the main problem is that there's no sure recipe, some chips can reach, say, 4.8ghz with 1.3v like yours, others maybe not even reach 4.6ghz with 1.3v, requiring even more voltage. Sorry, I don't know what an ASUS board bios looks like, but I think what you should do here is to reset your bios, then try to find a bios settings that manages your cpu voltage, it will probaby be set to "auto" by default, and it should probably be called something like CPU VCORE or just VCORE, dont mistake it with VCCIN our cpu input voltage.Īnyways, I'd set it to 1.25v, then go for temperature tests, if the temp is fine, start raising the multiplier by increments of one, notice on CPU z how your bus speed is 100 (rounded), and your multiplier 48, meaning 48x100=4800mhz=4.8ghz, your default multiplier should be 37, keep raising it to 38,39,40,41 and stress test each one for a couple of minutes, once you reach a multiplier value that crashes on stress test, then thats the limit for 1.25v, sorry but this is just a very very basic overclocking step, you need to read some guides about it.īut you didnt followed my instructions, it was unlikely to score 4.8ghz with 1.25v right off the bat, you have to work your way up until you find out whats the max frequency you can get from that voltage, and then build your way up to your desired relation between temps x ghz x voltage.
Just an example here, I'm using a 4770k, I run a 4.4ghz at 1.24V and i get 78C on stress testing and 68 while gaming using an H110i GT, to get to 4.5ghz I needed 1.27V, my temps rose to 84C on stress and 75 ish on gaming, while this is still fine, I'm conservative so the 100mhz tradeoff wasn't Worth it for me. It didn't boot before because for your chip, 1.25v is not enough for 4.8ghz, someone said here if im not wrong that they used 1.278v for 4.8ghz, remember you were at 1.3V for 4.8ghz, every chip is different, some needs more some needs less.ĭram voltage must be in accordance to your ram specs,wich you must know, some uses 1.5v, some 1.65 it depends on what you have. Thats the problem, there's no telling what voltage is the best for you because each chip handles voltages differently, what I would if i were you, would be to set it to 1.25v running at 4.2ghz for safety, check if your temps are alright, then start increasing your clock to 4.3ghz 4.4/4.5 until you find your max clock until your system fails to load, this is when you decide if you have more room for more voltage and then more clock wich leads for more heat or if you're at the best heat x performance spot.
