Moo Runtimes

[Fire$torm]

I was looking at my completed tasks on Moo's site and discovered some HUGE variation in run times. From a low of 2,300+ sec. to over 13,000+ sec. And the amount of time varies by date.

Nexus (My Desktop):
ID#- 297
List: Completed Tasks

Clocks
CPU: 2.8Ghz (Stock)
ATI 5830: GPU = 950Mhz / MEM = 900Mhz

Projects:
WUProp
FreeHal
MooWrap
PG-PPS (Sieve)
YoYo (Now set to NNT)
Aqua

Any ideas?

Note: I just up'd the 5830 clocks to 1000/1000 (Which MW did not like).

Edit: I put Odin (w/2x 4850) on Moo a short time ago and it completed its first wu in 4,141.21 sec.

4850 clocks: GPU = 700Mhz / MEM = 650

2nd Edit: WUProp Data on ATI Hd 5830 here.
