Okay, it has been awhile since I put together a new machine and I'm working on overclocking it manually as the settings in the UEFI put way too much voltage and I hit thermal max pretty quick during stress testing. I have managed to get it stable at 4.9 with 1.24 volts, LLC 7, stock cache speed and an AVX offset of 2. However, when doing certain tests (LINPACK in OCCT) it will eventually stop because a couple of the cores will eventually reach over 96c even though the AIO coolant is still 35c with an ambient temp of 21c. I am using a Corsair H115i and it idles around 31c and during anything other than small sets or the linpack, it never gets above 82 degrees.
My goal is to get to 5GHz with an AVX offset of 2. I think I can get there without a major bump in voltage, but I'm wondering why the AIO can't keep those couple of cores from reaching higher temps over a period of about 10 minutes of hardcore stress testing. If I can get 5G and keep the temps down during less aggressive testing (larger sets and an offset for AVX), I think I'll be okay.
Since I have gotten to 4.9 on 1.24 volts, does that mean I got lucking in the silicon lottery for that, but not in the heat generation area? Is it normal for the cores to keep jumping up a degree or so every iteration of the test until thermal max and the AIO's coolant staying so low (35c)?
Any input would be great. The last OC I did was a 5820K that I got to 4.7 on an H100i.
I put my system information in the signature. I hope it shows up.
