Go up one level in this thread


I have 4GB for main Memory, I am running Windows X64
the only 64-bit chess program i have to my knowledge is Crafty.
Chessbase and my Copy of Deep Shredder 9 are 32 bit.

Right Now I have a Single Dual Core 270 Opteron (2Ghz each core) i have an empty
cpu slot and 4 more memory slots.
I use 2Gb for Hash Tables and if i try to do anything else with my computer i
get Virtual Memory problems. It's not that i really need to check my email or
surf the Web when i am analyzing chess positions i am just uncertain why 2 Extra
GB isn't enough for the entire system.

The plan was to populate all Memory slots get another 4GB you can get 8 x 2GB
chips but that's really expensive.

I would hope that NUMA and 4 extra GB would  make a huge difference but i am
just asking opinions here.    1 would 16GB really be overkill Vs 8GB compared to
what i have now and
2 do you see any difference with NUMA etc.


Thankyou
