FX 8350 downclocking

[TheSebamed]

Hello!

As i was browsing through the Troubleshooting sections, looking for related topics already created by members, i did find someone's post about his voltage spikes on a fx 8300 cpu.
As i don't have that CPU, i thought of doing a new topic.

As i read the instructions, i will specify my PC specs before saying anything els in here.
CPU: AMD FX 8350 @4.0ghz (runs at 1.3V) default clocks
Mobo: Asus m5a97 le r2.0  
BIOS: 12/12/13 Ver: 04.06.05 ( Dx diag said so)
Memory: 4x4 Crucial Ballistix Sport (ddr3) 1600mhz
Corsair 550w PSU
and Corsair H55i (i think) watercooler for CPU.
After cleaning my PC, new thermalpaste and everything, my temps went down to 55-60oC (HWMonitor, under Mobo CPU temp)
Core Temp shows max 50 on my CPU
GPU: RX470 Sapphire nitro+
I am using Windows 7, just wanted to note this out as maybe someone will ask this.
After a while, my CPU suddenly just keep's downclocking itself from 4Ghz (1.3v) to 1.4Ghz  (0.8625v)

I did google this situation and there they told that it was VRM overheating.

That's because it's only a 4 phases for the CPU, and it doesn't even have heatsink.

Suprised you never noticed this, or is it a new system (hope not).

It will help if you direct one fan over the VRM and run it at sufficient RPM. MBs without VRM heatsinks tho.. who thought that was a good idea?

Does it drop while gaming or when you´re on the desktop doing nothing?

Not me . However, I use to use the Asrock 970M pro3 and it had no VRM heatsyncs and I was running an FX 8300 at 4.2Ghz @ 1.325V so IDK

Downclock it to 3ghz and lower the voltage as much as you can. If temperatures are okay and it still gets drops to below 2ghz territory, it's the VRM getting hot. If stable, increase clocks and keep the voltage as low as possible. You'll see where you can get it to run stable.

 

I hope this helps. Also, that fan over VRM solution is very much recommended

Thank you everoyne for those quick replies.
I put a fan on top of my case to blow air to VRM's and it actually helped!
Now my CPU does not downclock, thank you everyone!

Hello!

Thank you guys for your replies and helping me troubleshoot my PC problem. It took me awhile to mod my PC but it finally happened!
Decided to put a Fan that would blow air at the VRM. It actually helps alot!
