Guys,
on Rivatuner, there are 2 items for Oclocking.

What is the difference between the 2?

If I only do like the core, what happens?

pretty simple:

up core = up core
up ram = up ram

Right,

But what does each do specifically to the card? I mean, I realize that they go faster, but what is difference between the core versus the memory speed?

one is the frequency of the core one is the frequency of the ram
 
I think I understand your question, lol:

Core = fill rate
Memory = bandwith

i.e., you should be keeping them both up versus trying to concentrate on only one unless you have a specialized application intended for a specific use.

Thank you, Radiant.

One last thing. I understand the Bandwith part. But what about the fill rate? Not familiar with that.

Or do you know of a website that might explain the whole thing to me?

thank you
 
All you really should know, as I understand it (not big on OC'ing vid cards) it that if you overclock the core w/out OC'ing the mem, at some point the slower mem will become a bottleneck for the GPU, causing a drop in performance. (simplified version):cool:
 
I am pretty sure Iconz1 is right about the bottleneck therory. The PC2400 I am running with my A64 seems to slow it down and cause some pausing in games (when the PC should completely own the game due to its specs). I am getting my PC3500 today, which was delivered to my mother in laws. I'll be able to tell if it really makes a difference later tonight.
