LinX - A simple Linpack interface

I need som help here.

I have two computers here that I have been overclocking, and testing with LinX (newest verson). One of them has an Asus Commando P965 board, Q6600, 8GB mem and the other Asus P5Q Deluxe, Q9560 and 8GB mem.

The thing is that I get very inconsistent GFlops numbers with my Q9650 rigg. I get about 33 GFlops @ 3.82 Ghz, mem @ 1066 (266 strap). That is WAY to low!
With my Q6600 rigg @ 3.2 Ghz, mem @ 800 (266 strap) I get about 43 GFlops.

What can be the problem here? I'm really confused to why this happens.
Temps on the CPU is under control, so it is not throttling.

Edit : When I ran LinX I choose custom 6500MB of memory to use, and that seems to be causing my inconsistent GFlops numbers.
When I choose to use ALL memory, the resultes seem more correct. 43 GFlops for my Q6600 @ 3.2 Ghz and 54 for my Q9650 @ 3.82 Ghz.

Is this a bug or just how Linpack works?

Linpack indeed might be glitchy sometimes. For me it can repeatedly show 17-20 GFlops on some testing instead of usual 29-30 (pretty rarely though). LinX itself doesn't produce GFlops numbers, it takes them directly from Linpack's log.

I think that maybe it is the OS that has to be blamed. That is definitely not a common scenario for Windows memory manager when a process requests such huge amounts of memory at once. Maybe reducing background load will help stabilize the numbers.
