My 3770k linx only has 65 GFlops @ 4.2 Ghz

post #1 of 15
Thread Starter 
First time OC...
3770k with p8z77 pro

use asus' turbov evo and got:
BCLK: 103Mhz
VCCSA: 0.925
CPU PLL 1.8V
CPU Voltage: 1.17
DDR V: 1.5
Ratio: 41

Max Temp: 72C

Tested on LinX only got 56 GFlops...

I saw others all around 100+ GFlops

You need to update the Linpack binaries that Linx uses to the latest version. The newer linpack uses the new AVX instructions, which greatly increases the gflops. You also have to be using Windows 7 SP1 to run AVX instructions.

Here is the latest version: http://www.gigaflopd.com/downloads/linx/ If you have Win 7 SP1 you will see 100+ Gflops with that one.

it is win7sp1...
so, if i'm not using the linpack with AVX, my 56ish GFlops is about alright?

Thanks!!

I'm not sure, people tend not to use it without AVX these days, it's not as stressful. Just grab the new one and check what figures it spits out. thumb.gif

It's because ivy is a gflop.

Im joking, idk why.

As mentioned above it's because he is using a version without AVX.

downloaded the updated version and did a quick test with problem size of 13000,

it's now 83 GFlops....

Use the AVX Linpack it is a better stress test of all CPUs that support AVX extensions.

The GFLOPS seems consistent with what I remember my i7 860 getting.

I can't say for sure, since I don't have an Ivy, but my Sandy hits about 105 at 4.5GHz so it seems as if you may have something else going on here. Do you have turbo states turned off?
