AMD FX-8120 8-core 3.1 GHZ @ 4.5 GHZ
G.Skill 8GB DDR 3 1600 MHZ Ram
Corsair H100 watercooler
ASUS HD7850 2GB DDR5 Direct CU graphics card
ASUS M578l-M USB 3 motherboard
700W lite-on power supply
x7 120mm case fans
Windows 7 64 bit
I am currently experiencing issues getting my system smooth on 4.5 GHZ, I have tuned my bios
settings to be stable on prime at 4.5 GHZ but am having issues during 3D mark 11 benchmark tests. During the "physics"
test it will every 10 seconds slow down then return to normal. This also happens when playing CS - GO and other games.
When clocking back down to 4.2 GHZ it is stable and runs smooth during benchmarks and gaming.
I have turned off all the things in the bios that I should and have tried to adjust LLC (load line calibration). Have also tried under clocking/overclocking ram, ht link speeds ND voltage etc etc.
It just doesn't work!.
My power-supply is 700W but its cheap. I also have a very cheap mother board.
If anyone can help it would be greatly appreciated.
yes but overclocking is not a guarantee to reach a high overclock two identical cpus one could get 4.8 and the other might only go to 4.3 its all about luck and so many variables. you could get a quality psu but its a chance you would take and is it worth it for 300 mhz
if you but a new motherboard and psu will you be pleased with yourself if you reach 4.5ghz and will you be pleased at what it has cost you to get it if you think about it you could have just purchased a FX8350 instead to save the trouble
That is a native AM3 mobo I think. I am not sure and may stand corrected. but I know one thing clearly and it is that AM3+ socket is designed for higher peak currents 145 Amps (I think) while AM3 can provide 110 Amps.
This difference does affect OC ceiling. an upgrade to 990 FX chipset might be a good option.
p.s a quality psu like a 750 W corsair will be a great option as well./ but I am honestly not familiar with your current psu brand and its quality.
