Attempting to obtain a stable FX6300 using the HR-02 Macho cooler.
Just after 20 minutes of running SmallFFT with stock settings, AMD OverDrive was stuck at 20c thermal margin. I manually adjusted the vCore to 1.40V, but the hardware still displayed a maximum voltage of 1.380V and consistently showed around 1.356V during SmallFFT. Also, what does VID voltage mean? My setting is always 1.2125V.
Use Manual CPU voltage settings. The actual voltage still decreases even in manual mode, which is acceptable. The LLC configuration is meant to minimize this drop; increasing it to the maximum can further reduce the voltage loss.
Check CPU-Z for SmallFFTs over 20 minutes and see if any cores stopped working.
CPU-Z and HW display identical voltage readings. After performing the small FFT, all cores and threads showed no warnings or errors.
I'll handle it tomorrow, since I need to leave now. Thanks for the advice—see you then with the results.
No issue at all. If you don't respond immediately tomorrow, increase the frequency to 100mhz and run SmallFFTs for 20 minutes. Should no cores fail and no overheating occur, raise the frequency once more and continue with SmallFFTs. Keep repeating this process until a core failure is detected in SmallFFTs, after which increment voltage by 0.01 to 0.03v in steps. The safe upper limit is 1.55v; stay within that range. After testing again, if it fails once more, adjust voltage by 0.01 to 0.03v and continue until no failures appear. If successful, raise frequency once more and verify. Generally, a voltage of 1.55v corresponds to the maximum safe voltage for a 62c core in a 70c socket, which equals the maximum allowable temperature.
Hello!
I agree with your statement, and currently my CPU runs at 4100MHz and 1.4V (CPU-Z reports 1.380V, dropping to 1.336V under stress).
My latest SmallFFT took place for 25 minutes without any warnings or errors.
Current temperatures:
AOD thermal margin: ~19°C
HW CPU Package 55c under heavy load
HW CPU 59c under heavy load
Should I rely only on the AOD thermal margin? Since hardware has limited space for overclocking, but if AOD is accurate—19°C remains a significant amount to work with.
I’ll wait quietly for your advice.
Also, what is the VID voltage?
Stick to the thermal margin. AOD is the most precise temperature for any AMD CPU.
VID, or voltage identifier, can be a bit confusing but it's essentially a voltage value that the stock CPU asks the motherboard to provide. The VID isn't Vcore, and doesn't represent the actual voltage delivered to the CPU. Vcore is the real voltage supplied to the CPU, so this is what truly matters here.
Increasing voltage = generating more heat.
Continue boosting the multiplier until at least one or more cores stop working in Prime95. Try to achieve speeds around 4.3-4.4.
Once you feel you've hit your maximum overclock speed and are satisfied, run Prime95 for a minimum of 3 hours to confirm stability.
Will do!
About that VID I was just wondering what it is and too lazy to google it so thank you for information
If that's not a problem, I would like to keep this topic open, and after core fails after adding voltage as you wrote before I'll come here again.
My goal is to reach totally stable 4.300-4350MHz and that's about it.
I'll get you any informations about progress but probably tomorrow, will see.
Thanks a lot for all help and advices!
Cheers!
Anytime! Let me know how it goes.
