Just for kicks, I wanted to see if I can tune up my sig rig to run at a higher speed AND still be S&M stable.
So I took it up to 2.90GHz, and ran it through S&M.
This is actually the second time the rig passed at 2.90GHz.
The first time I forgot to take a screen shot
. In the interest of full disclosure, and with full confidence that the machine would in fact pass the stress test again, I ran S&M again.
It deprived me of a usable machine for several hours (and some people of some chat-enabled company), but at least I am running at a very confident and stable 2.90GHz now.
For the record, the test was run with ambient temperatures of 29.5 degrees C in my bedroom; my CPU cores peaked at 51 degrees C sustained during the hottest part of the CPU tests.
The big benchmark benefit of running the processor at 2.9GHz is a useful improvement in RAM bandwidth.
Obviously, 2.90GHz result is to the left, and 2.80GHz result is to the right.
I cannot honestly tell if 2.90GHz is faster at the keyboard level; 3DMark06, the only other benchmark I ran to gauge performance differences (I figured that the CPU is holding back my video card's potential), has not shown any performance gains either. Though the machine is obviously S&M stable, I am considering whether or not the increased stress is justified by the lack of palpable performance increase at the keyboard level.
I am impressed, however, with the welcome increase in RAM bandwidth; Blitz will tell us more about how close the new RAM bandwidth figures are to the theoretical maximum of my setup (as this is his forte).
Will I push to 3.0GHz? I may, to be perfectly honest. My instincts tell me that this chip may even be 3.0GHz-capable AND S&M stable...
But that is an adventure for another time. Edited by txtmstrjoe - 10/27/08 at 2:26am
