underclock saphire r7-370 4GB to reduce power consumption

Question asked by jsa83 on Nov 25, 2015

Hi,

 

First of all, my build:

 

Asus A88XM-PLUS

A10-7870K at 4.2 Ghz

8GB Ram at 2400 Ghz

 

Storage:

Samsung SSD 250GB

1TB WD Red

 

Power supply:

Seasonic G-550

 

2x 120mm Noctua Fans (1 on chassis and one on a CoolerMaster Hyper 212)

 

 

Problem: I want to add a Saphire R7-370OC 4GB version to it and my PSU fails to handle it during pretty much any game (windows is fine)

 

First of all, I'm surprised, I thought 550W would have been enough.

 

Second, I am unable to replace the PSU for now (to 650 lets say). I did notice sliding "max power" setting down in the new crimson suit did help the issue (I must only be missing a few Watts). Does this automatically underclock the core & memory of the GPU? Can this damage the GPU in any way? Do I also need to underclock the core & memory directly bellow the "max power" bar.

 

What would u recommend except the obvious of replacing the PSU? FYI, loading the fail safe Bios Defaults (=undo overclock) does not help.

 

Thank you for your help.

 

Go Red!
