Hi evryone after playing a lot of BF3 in the past days, I have gotten very tierd of the random lagg I get. The weird thing about it is that the game runs fine until I make a quick 180 turn, swap weapons, firing a shotgun or entering a "new" area. In short, when ever the computor is forced to load something new (a weapon ect.)

After looking into to my graphic settings I turned antisteroscopic filterng and some HBOA thing off I reduced the lagg a bit and managed to inprove my FPS. Though the lag is still there.

Allso, ever since I got the game I have had some weirs graphical glitches (textures being replaced by shadermaps, model faces flying around ect.) but they have gradualy decreased with evry new graphics cad driver Nvidia has released.

To me all of this points to to the computor being out of memory or not loading new stuff fast enough. So I looked at the resource monitor in windows and found out that I allmost don't have any memory left (50 mb or something)

Therefore im thinking of upgrading my RAM from my current 6gb to something better. But im not realy sure about how to do it. From what I heard upgrading RAM is just to open the case and plugging it into a open slot. But im not sure about how many slots I have left. Is there any way to see that without opening the case? Allso, does all ram devices have to be the same type or can I just get one that I think will suit my needs?

You will need to have the same kind of RAM. It could be DDR2, or DDR3 ( or I guess DDR if it's really old ) the easiest way is to just man up and open your case really.

Although, If you're on 6GB, I honestly fail to see how that's the problem, as I'm sure 32bit applications themselves have a 4gb limit. ( Could be wrong though )

If you have 6GB RAM then it's not a memory problem, because even today that's a LOT. As Indicium said, are you on a 32-bit OS? If so you are limited to a tad under 4GB, and that includes the GPU memory as well, so it's possible you may only be utilizing 2GB RAM if this is the case.

The simplest way to find out would be to open up task manager and leave it running in the background. Also download MSI Afterburner (or some other perf tool) and do the same. Play the game until it lags and then exit and see if the RAM peaked and started paging. If it's not the RAM then either your GPU is being maxed or your CPU is being maxed. And if neither of those are happening then it's most likely some sketchy drivers. Nvidia are usually quite good at fixing their drivers so if it is a driver issue then it shouldn't be a problem for too much longer - especially with such a popular game as BF3.

Correct me if I'm wrong, but even on a 64-bit OS, if the application runs as 32-bit, the application will only have 4gb available to it?

I've never heard of a video game requiring more than 4gb of ram. The game itself would be limited, but other apps can take other sections of ram, as a 64bit OS can assign other sections of ram.

The problem is probably you're running out of graphics ram. I'd recommend at least 1500mb of onboard graphics ram for modern high-end games running at high resolutions/settings.

What resource monitor is showing you only have 50mb left? What apps/services are taking up that much ram. It could be you're running out of ram, but it would be some app with serious memory allocation issues.

Im on a 64 bit system and BF3 is a 64 bit game, so that's not a problem. Allso I have had both the task manager and windows resource monitor running and looked at that and the RAM usage is constantly about 5gb and the rest is "allokatable or something". Allso the taskmanager says that BF3 only has about 2gb of ram to use.

I have an intel core i7 2600 and gtx550 ti so I don't think that shuld be the problem.

That's good to know but what I meant was more like if I have say DDR3 from company "x" I shuld be able to get DDR3 from company "y" without problems

Crysis sandbox after launching 100+ nukes It used 5.2 GB of RAM and crashed the nVidia drivers. Then my GPU overheated and my entire computer froze. Try it, it's pretty cool.

I'm fairly sure it's not a 64bit game, but okay. If it's only using 2gb itself, then something else is using RAM, which suggests you're running other programs in the background which will obviously affect your gameplay.

I have a 3.3ghz i5 and a 550ti and this system runs BF3 fine. I do have more RAM than you but I don't think that's really helping. You should try and clear your computer of the crap that is running in the background. Also it might be worth checking what make your GFX card is, i know that many of the manufacturers factory overclocked the cards and you might have been left with one that wasn't.
So it might be worth running this and seeing if any obvious problems turn up.
I also have a pretty fast hard drive and i'm not sure how BF3 streams the levels but it could be that your hard drive is having trouble loading the different parts up (i only mention this because minecraft used to only lag on my laptop when loading up new parts of the land). Worth a thought.

Ty for the replies evryone, I may not need new ram, but I like to have a lot of things running in the background to . I have had this problem since the game was released and allso I have had similar problems in skyrim.

I would be very suprised if it isn't...

I looked at the prices for ram and they seem realy cheap so unless there are any compatibility problems I think im going to buy it anyway...

Is there any weird problems that can occur when you have 2 diffirent kinds of RAM installed? They will be DDR3 of course

If you need to buy DDR3 memory modules, just note its fairly expensive last i heard. However, 6 gigs is not a lot of memory for gaming machine by todays gaming standard. Most max out their memory to around 16 gigs. On the flip side though, thats very expensive. If your having lagg issues with a online game, consider your internet connection speed. If your having lag on a non-internet based game, press ctrl+Alt+ Del and check your processes count. also consider MSCONFIG and check your startup processes. Best thing to do is visit your local computer repair shop and let them check it out. Hope that helps.

Unless you buy exactly the same modules, I would recommend removing the old ones and putting new ones in it.

Meh removing the old ones is silly,it caused a lot of incompability back in the day but it should all work nowadays. Just be sure to buy simmilar latency and frequency rams for example 1333mhz CL6. And voltage should be about right. Then you dont need to worry for incompability.

That sounds awsome!

Do you think these will work together?

Speed 1333 MHz PC10600

DDR3
DIMM
1333 MHz
240 pin
CL9


EDIT

I allso found this about my motherboard wich Im guessing means that this will be compatible unless there is a problem with having 2 diffirent kinds of memorys

Memory upgrade information

Shouldn't be any problem considering you're already mixing and matching your memory. I don't think you'll be able to use dual channel though

If you want the best performance out of your machine when playing games you should generally close down all unnecessary applications, and even disable your AV's real-time scanning if that is causing problems.

You might benefit from running other apps in a virtual machine as needed. For example, you could run most of your apps in a VM, then save and close that VM when you want to game. When you're all done, you can load the VM back up.

I used to do this for server stuff, until I got a dedicated machine for this purpose.

I had no idea you could do that, though the lagg in BF3 has decreased and the RAM seems realy cheap anyway so unless there is any problems with compatibiliy or something I think im going to get more anyway...

Go for it, but because it seems like your usage is extremely high, you might benefit anyway. Never hurts to try it out

Especially as running an app in a VM barely carries a performance penalty these days.

That's awsome! It's not really that inportant since I got rid of most of the lagg. But If I need it I will consider it
