BF2S Forums 7900GT problem :S

RAM.  You need more RAM.

i have 1 gb of ram and can run the game fine on high-med settings

I have a GB of video ram and it runs fine ;P

I have the exact same card and have absolutley no problems at all.

System Specs:

AMD Athlon 64 X2 4400+
4 Gigs DDR RAM
EVGA NiVidia 7900GT GPU
Sound Card: REALTEK HD 7.1
250 GB Seagate Baracuda Hard Drive
300 GB Seagate Backup Drive
Roswell ATX V2.01 SATA 500w Power supply

when you replaced your card, did you delete all video drivers and installed the proper ones afterwards (yes, even though they are both nvidia cards)? if not use driver cleaner to get rid of everything and reinstall the corresponding forceware drivers.

lag towards the beginning of the round sounds like pagefile access. i agree that 1 gig of ram is not enough to run bf2 @ high settings. check your mem usage during gaming (using the task manager is probebely easyest). does it peak to the max value (1 gig)? if you are accessing your hd for a long time (look at the hd inidcator) after you have joined the game, you are writing/reading from the pagefile. this is a performance killer. especially textures and terrain take up a lot of ram. try lowering the settings to see if the problem continues and possibly think about buying 2 gigs o' ram

CPU wise everything looks ok. i sometimes run bf2 @ 2.0Ghz and still get my 100+ fps with no lag

hd is ok too (try defraging once in a while)

sometimes my isp goes whacko and i lag very bad (huge ping). do you also get this problem in single player?

no... its a 7900 gt.. lol

So? Textures have next to nothing to do with the video card, only system RAM. To run high textures in BF2, you need 1.5 - 2 gigs of RAM, period (as you said).

omg, BUY RAM.

if you go buy 2x1gig sticks of ram, it will increase your game performance more than ANY video card you could buy.

i have an 7900gt to, and tomorrow i will be getting my 2nd gig of ram
hmmmm i think my eyes will hurt when everything is maxed out

ok, so I'm getting another 1GB but a few questions:

1. Can my CPU handle 4x 512 MB at normal speed (400MHz)?
2. Is this possible:
       2x 512 MB
       1x 1024 MB

thnx ,

1)yes, see above post

2) that won't run in dual channel mode

Hello -MIKI3.

   It is good that you are getting more memory, it will keep the game from paging the hell out of itself feeding that beast video card all the textures that it wants. . .   With regards to your memory configuration, there are really no issues with any configuration that you can possibly do; the machine will run, but not as best as it could.  Your memory will slow down to whatever point it has to to so that it can use all of the RAM that it has.  Least common denominator sort of thing.  To avoid this painful hit to your hard earned investment toward BF2 Ass Kicking keep a few rules in mind when you buy your memory.  I WOULD NOT DO THE CONFIG THAT YOU HAVE LISTED ABOVE!!!  I think you will regret it, you can disagree with me if you like, but please give my post it's due attention.

     Memory is all about timing and speed.  2GB will not be much better if it takes forever to fill up all 2GB.  The memory bus is not that smart, it only can do one thing at a time, and at one speed.  Bits will be saved to ram as specific speeds governed by the speed (400MHz) at specific timing sequences (4-4-4-12).  The first is the speed at which you can dump bits to RAM (depending on the ability of the RAM) and the second is the amount of time it takes to move that saved data within the memory module.

     Memory fills up and empties in order, one dim then the next, one bit, then the next.  Repeat when at the end.  It dose this the fastest when there are matched pairs of memory modules.  "MATCHED PAIRS" being the key words here.  If you install a config that has multiple manufactures, and multiple sizes your speeds will be greatly affected, as the memory bus will slow down everything to the slowest common denominator.  For example if your 2x512MB memory has a timing of 5-5-5-15 and your new 1GB stick has a timing of 4-4-4-12, under heavy load your timing could become as bad as 20-20-20-15.  That sucks hard core!!!

    What this means for you is that you should, depending on your petty cash and the price of the memory that you have:

A)  Find the exact same memory that you currently have (2x512MB) from the same company with the same timing / model number and install that into your other 2 slots.  NewEgg.com has tons of stuff available for under 100 dollars, but you may have trouble finding the thing printed on that sticker on the side of your memory.

- the alternative would be -

B) Buy a matched pair of 1024MB sticks (or better yet 2 matched pairs) and sell your 512's.  It may be cheaper to do this because your 512's could actually cost more because of their age.  One gets you 2GB and two gets your 4GB.

Either of these options would work, but please don't buy the 1GB stick to add to your current memory.  Bad idea, and not worth your investment.


Good luck, I know you will make the right decision.




P.S. Your processor is AMD, and AMD procs. are their own memory manager, it is cool because it is much faster than the external memory managers that you get with Intel procs.  But an AMD is only able to manage 8 Gigs of Ram per core.  Dual Core gets you up to 16GB of ram.  So the moral here is don't buy more than 8GB of ram, not that you would, but just in case you get greedy.  I bet your MB would not even know what do do with it.


These rules worked great with my 2x7900GT's

-AMD Opteron Dual Core 2.6 Socet 940 (280)
-8GB (4x2GB) DDR400 Registered (has to be registered with Socet 940)
-Foxconn NFPIK8AA-8EKRS Motherboard SLi (I got it because of the SLi)
-2 Nvidia GeFore 7900GT SuperClock in an SLi config
-HighPoint RocketRAID 2310 PCI Express x4 SATA II Controller Card
-5 Seagate 300GB SATA drives running in a 1.2TB RaidSet
-WindowsXP Pro x64

WOW, THANKS! That really helped me

ps. are these good:

that wont work in your motherboard.

but something like this would
