Will an extra gig of ram improve prfmc?

My current sys (MSIK8nSLi + AMD643200winni + 1gigDCpc3200 + Ledtek6800THD + 80gig Seagate cuda). I was thinking about adding another gig (for a ttl of 2gig). Will I get any better prfmc by adding the additional ram?
 
If you already have 2x512mb, you will actually get much worse performance because the Athlon 64's memory controller will have a hard time with 4 double sided sticks.
 
Its not going to improve FPS, but it will make your maps cached and thus you will usually be the first to enter the game in stuff like CS

It can also make a sizable difference in some MMORPGs, in both gameplay and loading times.

Run some games and then open up Task Manager. Check on the "Performance" tab and see what your "Peak Commit Charge" is. If it's over 1GB, then you may see a performance improvement with more RAM (possibly better in-game performance, definitely better loading times when switching levels/zones).

"Slow" RAM is still a few thousand times faster than your swapfile.

i personally don't know much in-depth stuff about a64 and its memory controller but if this is true then its something to keep in mind...

anyway its pretty much what everyone else said...
personally i like having 1.5 gigs over 1 gig cause i leave shareaza open all day sometimes and for some reason when i do this norton antivirus hogs up more and more ram the more stuff i download and only a reboot frees it back even when the files are done... so, this way even when norton is using a whopping 500-600megs of ram, you still have so much more to use and you can game away etc and not notice any choppiness...

but if you don't have this kinda problem than really the only benefit would be that some maps, textures etc would stay cached in your ram for longer and thus you would get lower loading times but no signicant fps increase i don't think...

looking at the RAM prices now - I say,y ou don't need a reason to buy more RAM

this is true, but if the "peak commit charge" is not over 1GB then mrudd will not benefit anything.

mrudd - what games? what type of improvement are you looking for? with that system it should be fine for any current game out
 
Make sure the memory is matched. Some 754 socket motherboards did not do well with too many sockets filled. Better read the motherboard manual before you decide.

he has a 939 board, was this a problem with them also?
 
bob, I play a Battlefield Vietnam mod called Point of Existence. Will play Battlefield 2 when it comes out in June.

how do you like that mod compared to dc/dxc for 1942?
 
The POE team has done a very good job on this mod. I really enjoy it. Best mod since DC.
IKE, why 2x1g instead of 2x512mb?
 
Because with 4x512 you must use 2T command rate wich is a performance killer.

OCZ has just come out with 2x1024kit that runs 2-3-2-5 1T but its $500, this is the stuff

But in general 2 x 1024, will always beat 4 x 512 performance wize.

 
Until the E0 stepping for A64 your going to have problems using 4 Dual sided dimms in a 939 system or 3 dimms in a 754 system in general depending on motherboard it will drop you down to DDR333 or lower speed when using 4 dimms, If I recall correctly from the tech spec's A64's can handle 6 banks of memory if they support dual channel and 4 banks if they support single channel this is of course at DDR400, they support more at lower speeds. Each double sided dimm is 2 banks. Hope this helps... 🙂
 
Arcanedeath is correct,

The E0 stepping of the Athlon 64 will feature an upgraded memory controller, among other things.

The Inq is reporting that one of the biggest updates to the upcoming E0 stepping of the Athlon 64 will be an improved memory controller, which will support double-sided DIMMs in all slots at DDR400 speeds. With the current Athlon 64s, you have to drop to DDR333 to make use of such a configuration.

For those out of the loop, E0 will also bring massive power savings due to the IBM strained silicon process along with SSE3.

If I am understanding you correctly, 2x512 qould be 4 banks and if I purchase a set of 2x256 (provided they were single sided), I would not lose any performance (all 6 banks would be used).
 
If you have already have a gig of ram then getting more than that will not help.

the only time that ram matters is if it is a mac or you are using apps that require alot of ram(photoshop being one of them)
