The Case Of Pc Stuttering

Run-time problems with RAM can be tricky to diagnose. Not dead RAM because if the RAM is dead the computer simply won’t start. The issue here is failing RAM. In this case, failing RAM causing PC stuttering.

What’s PC stuttering? It’s when one’s PC abruptly and abnormally pauses for a very short time interval, say maybe a few milliseconds. How can we tell? Sometimes, it may not show at all, but when stuttering happens it can be seen through the display on a monitor. What does it look like? It may appear differently for others, but on my computer it happened about every half a second. In other words, every half a second some animation or moving visual (like in a game) would quickly pause and continue as if nothing happened. This occurance led me to believe I had mis-clocked my RAM in my system’s BIOS. (For those who don’t mess with the system BIOS or don’t know what it is, don’t worry about it). So a few days ago I was hanging with James, playing some video games on my PC and I noticed the stuttering getting worse. It’s really annoying! I stopped playing and started reclocking the RAM. This went on for around three hours before I ran across a program to test RAM while looking at forum posts about improper RAM timings. I ran the program and it returned over 200,000 errors because of failing addresses. So, I tested each RAM stick individually to see if one in particular was causing all of the errors. Turns out, my fourth stick of RAM was the culprit. I had a feeling at this point that that RAM stick was the cause for all of my stuttering. I removed that along with its pair and left the other two sticks in. Then I rebooted the computer to find the stuttering problem was fixed! No more stutter!

From this I conclude that failing addresses on RAM can be cause PC stuttering. Simply removing the module with failing addresses can fix the problem.

If you think or are not sure that you could be having RAM problems, you may want to check out the program I used to test my memory called memtest86.

Go to the download page on memtest’s website and download the “ISO for creating a bootable disk (windows - zip)” if you are using windows or the linux edition if you are running linux. Then grab a CD to burn the ISO to. (Windows 7’s disk burner works fine for this. Just double click on the ISO and burn it to the disk.) The program is only 675KB large or less than 1MB so you won’t need a large CD for it. Then put the CD in your CD drive and reboot. The program should run at boot and automatically run. If the program generates errors, there’s a good chance you have bad RAM.

Hey I've had similar issues before. Thanks for posting with so much details. What I have come to understand is that my i7 Sandybridge 2600K could not keep it's overclock with 2800 cl9 ram. So from an oc of 4.5 to 4.4 fixed the issue for me.
