Attempting to obtain a stable FX6300 using the HR-02 Macho cooler.
Hi!
I got a little update!
Here is my little thoughts. If higher LLC set makes CPU hotter then higher vCore voltage and low LLC set, why would I simply make LLC on "regular" and bump vCore voltage to compensate VDROOP? I'm not going to do that, as I wrote, it's only my thoughts and I don't have money for new CPU in case of ultra fail
😀
Anyway, multiplier is now x21.5 which is equivalent 4315MHz, vCore under full load dropped a little, cause it's 1.368V (in BIOS still set on 1.4V, Medium LLC - lowered from High as it's still stable).
AOD shows thermal margin ~19c after 1hour and 15minutes of smallFFT. Ambient temperature about 24c.
Prime95 with it's smallFFT showed 0 errors, 0 warnings for every core.
HWinfo (I know you don't like it, but I do cause it can log any changes
) shows something weird..
CPU Clock line shows that "Minimum" clock was ~4068MHz and "Maximum"+"Current" = ~4314MHz... Maybe I'm just busting my balls, but 300MHz in clock monitor is quite a lot... Is it possible that overheating VRMs lowered clock while CPU peak load? I wasn't watching it closely while Prime95 was working..
BTW: yup, my VRMs are overheating but I'll solve that problem in next week!
All sounds good.
Initial settings for LLC and Vcore don't necessarily raise CPU temperatures significantly. The voltage isn't always exactly what you want. Under load, the CPU might receive only 1.35v instead of the desired 1.4v. This issue is called Vdroop, and LLC aims to narrow the difference so the voltage stays as close as possible to your input.
Don't worry about HWinfo; a slight and short-term drop is usually unnoticeable. If you consistently see a stable 4.3 on CPU-Z and AOD, that's what you're experiencing.
Consider replacing the small 40mm fan with one for the VRM heatsink.
Hello Benjiwenji,
I returned home after two weeks and completed VRM's issue. I purchased two 50mm fans to cover the entire hot area; one side of the fans is positioned higher so that hot air escapes through the removed I/O panel gap. I also needed a single 40mm fan for the front lower heatsink, which was overheating too. Now both VRM's heatsinks are reachable even under heavy load, and you won't burn your fingers. The current CPU clock is 4.314MHz, which is perfectly fine for me since I prefer more than just MHz for stability. I’ll remember all your advice and really appreciate every tip you gave.
That really helped!
Take care
