Gflop count!? How to get it higher?

post #1 of 6
Thread Starter 
Hey, ive encounters a weird issue. I run LinX to stress test my systems, and the gflops are constantly different, they have absolutly nothing to do with ghz and they respond to vvt changes quite a bit, but what else do they respond to?

I'm asking because at 4.0ghz I got up to 60gflops, about a week ago. Same sort of thing with 4.4ghz but over a month ago. I got 56.5 gflops. Earlier today I was getting only 40gflops, was messing around with voltages and increased vvt from 1.275 to 1.375, this bumped my gflops to 55.75.

I want those 60gflops again. Anyone have an idea on what other voltage I should focus on tweaking?

Gflops response:
Ghz: Nil
CPU PLL: Nil
VVT: Yes

I had that problem where my E5300 would give me a -much- different result in LinX, its turn out the best way to get the best score is to restart your system, disable or exit ALL programs in the system tray and then Run LinX to get the most accurate result

you have to use the same problem size and ram amount to compare Gflops, different problems use the CPU in slightly different ways

^ that too

Another problem is the timer resolution.

The applications used to benchmark might get UI facelifts now and then, but many of them still have the interior first developed with a few GFlops was high end.

The tests may be too short, the timer resolution too coarse, and if that's the case I'd expect to see variations so wide that the results would be nearly meaningless as a benchmark.

Indeed, ANY interruption (pre-emptive task switch) would greatly affect the test, and the moment the test started relative to the boundary of the timer's pulse would change the results....sometimes drastically.

ALWAYS run Linx immediately after a fresh restart - this has the biggest effect. As mentioned, also make sure you have the same problem size every time and that you aren't doing anything else with the computer/there's nothing else unnecessary running in the background.
Finally an update
