Power

post #1 of 6
Thread Starter 
So I am continually getting issues that I am not receiving enough power on my GTX680 4gb model o4g-p4-2686-kr and my memory is defaulting to 1066mhz or so despite being set to 2133 in the mobo. Additionally the cpu is slow to respond as I have intel speedstep enabled and it takes forever to clock back up to higher speeds,

Relevant equipment on the AX1200i:


Asus Rampage IV Extreme
2 x MCP655
04g-p4-2686-kr (Dual displays, one 1920x1080 via DVI-D, one 1208x1024 via DVI-I, both 60Hz)
2 x FP600BK and by extension 12 x CFT12SB4
5 x R4-S2S-124K-GP (2 attached to mobo, 3 attached via 4pinpsu to 3 pin 12v)


My question is this a faulty PSU? Wouldn't this PSU just supply more and more power until it crashes though? I've had no incidents with that solely the computer programs running at lower clocks. Is this a mobo issue then as they are slow to respond? I know that I can adjust clocks through Nvidia programs, is this all I need to do? Any help would be appreciated as I will exchange for a new one if this is not user error.

EDIT: Memory clocks are result of CPU-Z system analysis, bios says its clocked to 2133Mhz; Why would this occur?

First set the "Optimum Defaults" in BIOS, set XMP, then check for correct memory voltage. More later, I'll snap some shots of the BIOS settings concerned.



You can tweak memory clocks later.

Is it preferrable to use xmp or to set identical settings manually? It looks like it only changes 4 timing setting frequency and voltage

Actually, neither as XMP settings are not usually the best the memory can do. Its best to find the maker's site for your memory and set their recommended voltage, speed and latency numbers for the memory's best rated performance.

It depends. If you want to "set it and forget it" at the manufacturer's rated speed on the package, XMP is the way to go. If you want to squeeze every last bit of performance out of it, overclock it manually.

What about setting XMP then tightening the timings?
