I Have a Nervous Monitor

[Texun]

Maybe....... or it might be something else.

Tonight I noticed my display would start to jitter very fast, moving side to side or up and down about the distance of a few pixels at a time. The only time I have seen this was when I tried to unlock the other cores on my X2-555BE so I set it back to just 2 cores and haven't seen it since.

I have no idea what is causing this. The only recent change was the addition of SP2 for W7x64. I dumped the Catalyst drivers and reinstalled them fresh from AMD but my monitor still gets the jitters. It comes and goes every few minutes and it doesn't matter if I'm looking at the desktop or a web page.

I don't have any spare cards or monitors to test with at this time. Anyone seen this before?

Specs:
ASUS M4A770D
6 gigs of G-Skill
500W Antec PS
HD4670 \ 1 gig
Dell ST-2410
2 Hard drives
2 DVDRW's
SB Audigy

WTF? I just noticed my spell checker suggested ANUS for ASUS.

Potentially a power issue since you noticed it when the cores were unlocked it may have effected the signal or power sent to the monitor.

That happened to me when my overclock was unstable or CPU was running high temps with the overclock before I got a new cooler. This was with an X3-720BE.

I forgot that I had a mild overclock on the CPU and have now set it back to stock and will see what happens next. This sucks. Sometimes it does the jitter thing for 2-3 seconds, which is just enough to screw with my eyes big time while I am trying to read, and then it clears up and works fine for several minutes.

It could be the CPU. It wouldn't work with 3 or 4 cores unlocked and it never would take much of an overclock. Maybe I got a dud.... if so then it's the first one in 20 years.

Oh I forgot to mention I had a similar mobo to yours. Asus M4A77TD-pro, it could be related.

Ohhh... Maybe spell check was trying to tell me something.

I checked the card for heat and there's no problem there. I returned the CPU to a stock clock and the display was stable again, but I hit the sack shortly after that so I haven't spent enough time to know if that was the problem. I have my doubts should know for sure today.

Thanks for the tip on the mobo. I'll check the ASUS forum and see if others have had issues like this. I never use their forum because most of the time it is just too slow.

OK - monitor is fine and so is the video card. I backed off the overclock last night and the screen jitter has not returned. All voltages are still on the mark so I guess the problem was or is with the CPU. I'll leave it stock for now and may replace it if the problem reoccurs.

Thanks for the tips! :thumbsup:
