I was playing Crysis and a red screen came up and said something about memory dumping files...It stays up for like 2 seconds so it doesn't give you time to read the actual error...last time I saw one it was a blue screen that did the same thing...

I downloaded memtest and ran both sticks and I received errors...I will post those screen shots of the 2 errors I got in the first 30 seconds of testing...

Is this bad ram?

Thank you

Under Resource monitor which is a feature available in Vista...It The memory is going from 0 Hard Faults/Sec up and down and all the way to max which is 129 Hard Faults/Sec... IS that bad?

Well I tested both and one of the sticks seems to be the problem...

Right now I have the good 2gb stick in and its only using 571MB of memory with Windows media player on and safari open...and PCu usage is going not going down from 50%...Its staying between 50 and 65%....

What the hell is going on? Why is it when I have 4GB in the memory usage is at like 1.4Gb..but with 2gb its at 550?

Also, Crysis used to only use 1.5GB at all times, and earlier when I was playing with 4GB< it was using 3.8 or so... What is going on


Thanks

It might be a background app or even a virus/spyware.

Well there must have been *some* process suing the CPU...

Anyhow, there are *semi* random events that could lead to this, a scan process starting (av, antispy, windows updates, indexing service for an app). A web page with non-static content will increase usage... its hard to tell, however it *sounds* like some type of scan (which you interrupted by rebooting, and will restart at some point).

Similarly its ahrd to identify why an application is using more or less RAM. Maybe a certain aprt of the game requires more elements to be loaded, perhaps you misidentified what was using the RAM and it was actually shared with another applicaiton, etc.

Its all a bit of a black box, you can do some investigating, but you can never really identify why an applicaiton uses more or less memory.

Anyhow, RMA the RAM.

I run Crysis on 2GB running at 1280x1024, high settings, no AA.

Of course, i'm on XP, which means 2GB feels like 4GB would on Vista!

Well I was running High DX10 No AA with 4GB and getting 40Fps at all times...

Now with 2GB at High DX 10 No AA I can't get like any Fps cause it just skips around all over the place and lags...

I checked the task manager and it was using all of the 2Gb...

With 4GB it uses like 3.6GB or something...

But before, on the same levels and maps and stuff, it was only using 1.5GB all the time, and I have heard others reporting that Crysis only uses like 1.5 to 1.7 GB...

This is weird

Vista's the problem then. What a surprise...

Alright this is totally messed up. I set them to 2.2 and put all 4Gb in. Played Crysis and it used up all 4GB again and it took me like 10 minutes just to exit the game and then the computer froze... I'm looking under CPu-Z right now and the memory Frequency is at 400 MHZ...Shouldn't they be at 800?
