It's because you're running with HT off. Check the other submission with HT on on
Gulftowns in this thread, and you'll see that Ivanqu is well in line.
Newhit - 4725MHz - 44 GFLOPS
BobyTT - 4715MHz - 55 GFLOPS
Mydog - 4710MHz - 49 GFLOPS
myself - 4700MHz - 44 GFLOPS
Can't speak for the others, but FWIW I was running around 1800 for the memory, somewhere around 3GHz for uncore. Not terribly ambitious, but about as far as made sense to me to run 24/7. Not purposefully crippled, but nowhere near pushed as hard as possible. Chances are I was probably surfing the net at the same time as running it as well. Sure as hell wasn't making any attempt to break any GFLOPS records.
Now we could decide to be stability nazis and enforce shutting down all services and whatnot, but AFAIK, this thread is more about having fun than being some competition with heavy stipulations.
Of course, it doesn't surprise me that the bickering and calling people out as "cheaters" etc is occurring...it's bound to happen when people spend a lot of time and money to find a good chip and coax everything they can out of it, only to see someone else with a result that's better. Human nature, I guess, to try to dismiss it on any grounds possible.
