Not sure if i should keep or exchange this Matrix for another one (i believe my local shop wil let me return/exchange within 7 days)
I'm at work so i dont remember the exact settings but off the top of my head:
Core Speed: 1240 or 1250 but anything after 1250 its unstable
Core Voltage: 1.27v (default 1.2v) - at 1270+ it doesnt matter how much voltage i pump it artifacts, went up to 1.35v
Memory Speed: 1775mhz
Memory Voltage: 1.65v (default 1.6v)
Fan Speed: Manual - aggressive id say, fan hits about 70% once 60C is reached
Power: +20%
LLC: 100% (i notice at lower LLC when it crashes, the voltage fluctuates a bit, setting it at 100% seems to stabilize)
Temperature maxes out at around 70C in Heaven, 65C in game play (tested using Crysis 2 and Left 4 Dead 2). Air flow is pretty good - i have 3 intake fans, one huge one in the side, 2 from the top and 1 exhaust fan at the rear of the case. Big CoolerMaster HAF-X case.
100% Fan speed is just too loud, i guess some people dont mind it..but anything over 60% and its noticeable.
Outside temp is about 17C (separate bedroom, cold)
Was really hoping for 1300mhz, at least 1275mhz, but 1240mhz seems kinda low for this $500 card.
What would you guys do?
Update: I've figured out how to "de-link" the core speed and voltage AND set both Fan1 and Fan2 speeds via GPU Tweak, these are my current gaming settings
Core: 1265mhz
Voltage: 1.30v (default 1.25v)
Memory: 1775mhz
Memory Voltage: 1.65v
Power Target: +20%
LLC: 100%
Fan1 and Fan2: 60% (Manual)
Temp: 65C Max in Crysis 2, other games about 55C
I use these settings for gaming only, then drop down to default reference speeds/auto fan speeds when playing old games like L4D2
