Hi guys,
I am trying to overclock my CPU ( FX 8320). After many failures, I manage to find 4,1 GHz OC, which looks stable ( passed 10 minutes i OCCT). I know that this isn`t long test, but In real life scenarios so heavy load for CPU is not rather common.
My specs are:
- Asus M5A97 r2.0
- GPU: GTX 970
- CPU AMD FX 8320
- PSU OCZ SXS2 600W
- Cooling Fortis v2
Nevertheless I would appreciate your advice In the following case:
I overclocked only by multiplayer and I set LLC on AUTO. With AUTO setting I see the voltage drop on heavy load to even 1,272 voltage despite the fact I set manual CPU voltage on 1,38 level. I know that this is LLC function - to create voltage margin on CPU load ( in case of spikes)
but
With LLC set on Desible I see that my Vcore (monitored by HWInfo) reach the level about 1,404 (despite the fact, that CPU voltage is set in BIOS on 1,38) on heavy load, which affects temperature jump over 65 (despite quite efficient cooling), but more disturbing fact is, that above 1,4 limit I start to hear strange squeaking noise located near to CPU socket - but I think is from MOBO. The questions are:
1. Those kind of sounds are normal? Does someone know what those sound are, and are they safe? Can I ignore it?
2. Is it normal that with LLC set on disable I get higher voltage, than set in BIOS?
It is quite annoying, as I passed my OCCt short test having voltage fluctuation (from 1,272- ~1,33), and with LLC disabled I get voltage higher than 1,404 (which exceed what i set in bios and making the strange noises). Moreover it looks that 1,4 voltage is too much, and CPU will manage to be stable will lower voltage.
3. How to force system to keep my defined voltage setting in BIOS?
I am asking about this, because I see that I manage to pass the OCCT test (with 4,1 ghz) with voltage fluctuation (from 1,272- ~1,36) - which is below my BIOS limit. So setting fixed voltage I could get stable higher OC + low temps...especially, as the system doesn`t even need the voltage I set on BIOS = 1,38. Or do I missing something?
I would like to reach 4,2, but my system crash with LLC = auto or eneble - probably due to too low voltage (when I experience voltage drop), and with LLC=disable I get 1,404 voltage - which gives me too high temps+strange noises.
I can`t find setting, which would give me constant stable voltage set in BIOS (which is 1,38).
thx for help!
