I used to run a 4.8GHz OC on my i7 2600K (Noctua NH-D14 cooler), with a vCore around 1.38V iirc.
(also, recently updated mobo BIOS, and it requires a slightly lower offset voltage to reach the same vCore. strange)
Anyhow, I don't recall if I tested this prior to flashing the new BIOS, but I reentered all my settings correctly, and first tried to figure out the right offset to get the same vCore.
Testing (using CoreTemp to monitor temps, LinX with medium-ish problem sizes to stress CPU (16000-20000) shows temps reaching into low-to-mid 90ºC range! I DEFINITELY never saw that in the fall (when I built this machine and initially OC'd it).
Right now OC is at 4.6GHz @ 1.35-36 vCore, and I'm still hitting those temps.
Even with A/C, the PC is in a second-story bedroom and this room never really gets amazingly cold. With A/C thermostat is typically set for around 75ºF, in the winter heating is usually around 66ºF. Inefficient/drafty windows and whatnot probably means ambient temps in this room have a wider difference than those figures.
But, I'm thinking I'm basically going to be forced to drop the OC (mainly the voltage and get max OC from say 1.30V ?) just to keep the CPU temps at a reasonable level during extensive usage. It clocks based on usage, so it's not at those temps 24/7 (that, and I use hibernate when away for extended periods of time, like work and sleep), and I don't stress the CPU often (maybe a few hours here and there for games), but I imagine I am correct in assuming I definitely want to keep the temps a fair bit lower than I am seeing during stress tests?
So bummed about this.
For reference: CPU at idle is showing 40ºC - I cannot recall, but I do think I saw mid 30s in the fall (I didn't pay attention to clocks/temps in the winter - I figured: good in the fall - gotta be fine in the winter still).
I have been having a problem with BF3 freezing, but I don't think this is the cause - I don't think I was showing above a true 85ºC reading (75 in Asus's AI Suite, which I use to record temps during gameplay when I want that) - and generally, even games like BF3 don't stress nearly as hard as LinX. Especially since BF3 tends to crash (since last update/DLC) in the first few minutes.
Anyhow - have I figured this out correctly? Basically, I must downclock/lower vCore a bit?
