9370

Hello,

 

At the start of this year I bought the parts for my first build:

CPU : AMD FX-9370

Cooling: Corsair H100i (with 2 noctua NF-12 in a push configuration as intake)

Motherboard: Gigabyte 990FXA-UD3 (rev 4.0)

Memory: Corsair vengeance 8GB (2x4)

Graphics card: AMD R9 270 2GB

Storage: WD 1TB caviar blue

Power supply: Corsair CX 600 80+ bronze

Case: Antec P100

Ventilation: 2 noctua S12 at the front as intake and 1 of the case fans at the back as exhaust (I have the H100i's stock fans in case I need to replace a fan)

 

I bought this computer mainly for molecular simulations (they use only the CPU) and to play a bit. I have no problems while playing. When running the simulations (they have the same effect as a stress test) I can choose how many cores are used and using 6-8 cores for the simulation I get thermal throttle in under (10 , 5 or 2 minutes respectively). The CPU should not throttle as the temperature is at or under 50 C (I used speccy and AMD overdrive to measure temperatures) and I should still have 11 C of thermal margin according to overdrive and the information that I can find online. When the CPU throttles the multiplier drops to 7 and once it begins the multiplier drops every 15 to 20 seconds.

 

[I am not an overclocker and have very limited knowledge of it] I am running at stock clock speeds (4.4Ghz), turbo boost is off, I have tried turning C1, C6 and "cool n' quitet" off with no improvements, I have under-clocked to 4.2 Ghz (also no improvements) I tried 4.0 but I could barely boot.

 

Before this configuration I had the case fans at the front as intakes, the Noctua S12 as push (exaust) on the radiator and one for the H100i's stock fan as intake at the back and it was very slightly better.

 

So what I am desperate to know is.. am I doing anything terribly wrong? What can I do to prevent this? Should I just give up and try to trade my CPU for an 8350?

 

Thank you for your time.
