Why does my desktop Celeron 600 @ 1008 cruch at 1.065 points per hour using SSE

but my mates laptop 1000MHz celeron crunches proteins at about 1.8 points per hour?

Well the Tualatin Celerons had 256KB of L2 cache compared to the Coppermine's with their 128KB of L2. So that could explain his performance increase.

i'm guessing you are running gromacs on both of these machines.

in order to answer you question the right way i would really need to know what kind of memor you are using and at what speed these are running at?

Looks like it could be a combo of the coppermine and WinME slowing that desktop down. ME is not only the worst OS ever massed produced, it's a slow folder. :D

well the answer my friend is in the mem benchies....seeing the lappy with a higher score means the memory setting are probably more aggressive.

Gromacs love a big fsb speed or faster memory timings

try turning up the memory timings or the fsb on the other machine.

that should help get the frame times down a little.

I think the Win2000 Tualatin laptop is doing that p909 protein at 1.983 points per hour...

I've boosted the fsb on the desktop as high as it will go (600 to 1008 isnt bad). I actually havn't tried changing the memory timing at all.
hmmm, thats a nice HDD stui


BTW Is the Thermaltake Volcano Spark 7+ for the P4 a good heatsink?

Well the Tualatin celeron of that vintage was a just PIII on a smaller die wasn't it? Still, it's throughly entertaining :D
