Last week, I upgraded my processor, motherboard, and RAM to a i5-14600KF, an MSI Pro Z790-A Max Wifi, and some Corsair Vengeance DDR5 6400 CL36. I've got a pretty solid cooler and intended to give my CPU a moderate OC to 5.6GHz. If only it were that easy.
My initial overclock was also an under volt to 1.25V, which I saw a few youtube videos recommending. That worked OK but I noticed in HWiNFO that my clock speeds were throttling down to 4.8ish under load. I upped the voltage to 1.35V and the throttling actually got worse. I noticed that on the 1.35V OC that I was hitting my 181W PL so I raised the power limits to 200W. I was hopeful that my initial issue was caused by insufficient power and that my new issue was caused by too much power for the limits.
When I relaunched this time I was pretty hopeful but that didn't last long. I looked into HWiNFO a little deeper before running Cinebench and there were moments when it was throttling down to 4.4GHz AT IDLE. I went back and changed my ICCMax setting to Enhanced in BIOS and set my CPU Current Limit to 200A and still there was throttling. At that point I decided to drop back down to default BIOS settings and check performance.
At default settings I had some of my worst performance. Throughout all of the changes I was getting "IA: Electrical Design Point/Other (ICCmax, PL4, SVID, DDR RAPL" and "RING: Max VR Voltage, ICCmax, PL4" warnings in HWiNFO and I had hoped that would stop at default settings, it did not. Not only was I getting those warnings, but for the first time I ran into thermal throttling on top of them. My clock speeds were down to 4.0-4.2GHz and the card was pulling like 1.47V max which brought my temps all the way up to 100C.
At that point I went back to the 1.25V 5.6GHz setting and made a bunch of hail mary changes in BIOS (Disabled C-States, EIST, Speed Shift, messed with LLC modes) in an attempt to get it stabilized but in the end I was right back where i started. I'm getting 4.6-5.0GHz under load with power draw below 180W, VCC at about 150A, and thermals below or at 80C. Now, even while throttled this CPU is worlds faster than my 7700K was but that doesn't alleviate my concern that something might be wrong, whether it's the CPU or Motherboard.
On top of all of this, I was also struggling to get my RAM to run at 6400Mhz. XMP failed to post and the only way I got it to start at 6400MHz was by using memory try it! which raised my latency and voltage significantly to achieve it. A sane person would simply give up, set the RAM to 6000 CL36, and deal with the throttling, but as I said, I am concerned something is wrong with the board, the chip, or my head and I would really appreciate any assistance at all. Thanks guys!!!!
Just to add, I immediately updated my BIOS when I launched the computer. So if anyone is worried I fried my CPU just know it only had about one or two launches on the old BIOS firmware.
