Memory Controller Load 100%

Hey there,

I keep running into a weird problem when playing Killing Floor where the game will randomly crash and according to GPU-Z the Memory Controller Load is at 100% and will not drop even after the program has been closed for a while. It's fine after a reboot, but I'm wondering why this happens and particularly why so fast. I'm using a GTS 250 512MB card on a quad-core processor, 6GB RAM, and Windows 7 64-bit. The card definitely isn't overheating (that was my first guess) as the crash happened even at 62C. Any ideas?
 
Maybe a memory leak? have you heard of any others experiencing the same issues?
 
Multiple people have, but the other symptoms they experience and solutions are all over the place. I tried messing with the setting and it managed to run at the highest settings perfectly last night as long as anti-aliasing and motion blur were off. I kicked the anti-aliasing up to 2x and within 5-10 minutes it was at 100% again. Turned it off, still at 100%, but no crash. I can live without AA and motion blur in that game, but I'm wondering if this will be a problem in other games as well or if Tripwire just coded something strangely.
 
512mb isn't alot of vga ram. the memory controller on the gpu is probably off-loading some of that data into system memory...and if doing so caused a slight stall, the game could very easily crash.
 
The highest the card comes with is 1GB, so I'm kinda stuck in my price point. But even if it were offloading some of the work, I've got 6GB RAM in the machine, so it should NOT have a problem processing the information.

It seems to be a problem with the way the Unreal engine is coded. A Tripwire mod said that it's not too great at condensing requests, so if a lot is going on (which is definitely the case in Killing Floor), then it can get overloaded pretty quickly.
 
Yeah...but GTS250, I'm sorry to say, isn't really a stellar vga...it's actually one of the slowest on the market today. Anything that might impact it's performance is going to do so DRASTICALLY.

One of the slowest??, give me a break its not by any means the best though it should cope with medium gaming easily, and I agree on the memory point 512mb might not be enough what resolution are you running at? anything above 1440x900 and you really need 1gb of video memory.

I understand you have 6GB of system memory but thats much slower than gddr3 which is what I presume your card is and if the card doesnt use hyper memory or whatever the nvidia equivcalent is then all the system memory in the world wont help when you run out of video memory, I suggest running at the above res or lower to see how you get on.
 
Will certainly be upgrading once I have more expendable income, but when I built this tower, the card was $130 and I didn't want to go much over that considering how quickly video cards are outdated anyway. I'm not going to try playing Crysis or anything, but so long as it can not crash during Bad Company 2 (getting today) and a few other of the current gen games, I can live happily with lowered settings.

For the past week I've been running 1920x1080 due to a new widescreen Samsung monitor, but the crashing was happening on the older monitor at a much lower res.

I'm using DDR3 RAM. This kind, to be specific: Kingston 2GB 240-Pin DDR3 SDRAM DDR3 1066 (PC3 850...

As I mentioned if your card doesnt use turbocache that enables it to use system memory as video memory then it wont matter what memory you have, and even if it did turbocache and hypermemory is crap.

Have you tried uninstalling the drivers, using something like driver sweeper and then reinstalling them?

By the way your not using the drivers from the cd by any chance are you ?
 
Yeah, I uninstalled the driver last night, used driver sweeper and then reinstalled. Got the driver straight from nvidia's website.

Is it just this particular game? try and reinstall that, obviously save your game saves beforehand.
 
Yeah, it's just the one game. Which is fine, I can live perfectly happy without AA on something that moves as fast as that game does. I just don't want crashing, which tweaking managed to avoid. I mostly was trying to ascertain on other forums if the card needed to be RMAd (was idle at 54C, but I managed to get that down with fan speed) if it was the game, the driver, or just that the card was insufficient overall. Seems to be a mix of insufficient GPU RAM and the game itself.
 
just change drivers, you people really have no clue to what a memory controller is...

could you also tell us what PSU you are using?
 
iv found that my card does the same thing (gtx260 216core) in lower dx9 games its when my drivers crash then the Memory Controller Load goes to 100% it only hapends to me when i alt tab or play old games alot of hl2 mods dont like my over clock id say try running the game an an admin or update your drivers. the game still runs for me when the drivers fails but it drops down to 2d clock speeds.
