but about 3.4gb bandwidth on 2gs of memory is all you need.
not hardly....look at all these games like BF2 and FEAR that suck the living hell out of your bandwidth.....there is no such thing as 'all you need' IMO...there can always be more and more is better.
It's the fact of having 2gb over 1gb that helps, but as far as memory bandwidth goes, 6.5gb/sec+ helps a good deal in gaming...this is primarily why you see the higher scores in aquamark and such is because of that.
As far as your RAM is concerned...even if your RAM is capable of getting up to 300MHz, your motherboard won't handle it...the north bridge won't be able to take it without extra voltage and really good cooling.
This was on my socket A system:
DDR490 - 245MHz - 3-3-3-8-1T 2.8v, VDD1.6v @ 3716/3433-
Test 2: 5 minutes, Vdd1.7v - Merlin BIOS
3.7gb/sec memory read rate and that's with it at 245MHz as you can see.....
this is on my AMD64 using two different benches, one sandra the other everest:
DDR520 - 2.5-3-3-7-2T 3.0v @ 6033/6080 (7031mb/sec with Everest) (2.607GHz) 324x8
Of course that one is 260MHz not 245 like the other, but theres a significant difference in bandwidth. At 245MHz it reports mine at 6.5gb/sec in everest so that's basically double as to what you get on a socket A system....
No doubt when AMD goes to DDR2 with an even further optimized memory controller you'll be seeing 10gb/sec+ easily.....that'll be nice
I use super pi to guage performance (ill probably be told that this is crap form of benchmark though).
nah super Pi is used by a lot of people....it's purely determining your CPU's number crunching abilities and of course also banks off your RAM....
however if your friend has a lot of **** running in the background while you run super Pi on a super clean install with nothing running in the background that'd obviously give you an advantage.
Also try going into the task manager and setting the priority for the SuperPI process to 'realtime' I generally would gain a little bit of speed when I did that
