Sooooo there I was with the 3DMarkVantage sitting on my computer for the first time and decided to give it some....
I set my clocks for what I used in 3DMark11 and hit 'Start Benchmark' 3 or 4 seconds into the bench, it crashes and I scratch my head and decide to lower clocks. I knocked off 20Mhz on both the GPU clock and Mem clock and blow me, it crashed again after 30ish seconds.
Not to be beaten, I go for a simple overclock and it passes the test without fail. I start upping the clocks and rerun the bench again and Success! I continue doing this untill I reach the clocks I had passed 3DMark11 with and again success! As it was very cold when I was doing the benching, I decided to open the door and go and pop a jumper on bumped my clocks again and another pass.
Now obviously I understand the cold temps allowed me to go higher on the clocks but what puzzles me is how come it didn't want to play at the very start? Is this normal for others...Does the GPU need to warm up so to speak before allowing a decent overclock? This isn't the first time I have noticed this either, as I had to do the same when I ran 3DMark11.
TL: DR
Anybody else find they have to 'warm' the GPU up before hitting big overclocks?
