• HD 6870 green artifacts. Idle clock speed too low?
    5 replies, posted
I was watching a youtube video earlier and it was extremely corrupted and green etc. However when I turned down the quality to 240p and it worked fine. I updated my drivers, restart my PC and still its happening. After a bit of googling I found someone describing the exact same problem, apparently caused by the idle clock speed being too low? I havent changed anything that I know of, the only thing I can possibly think of is that I have been playing a lot of Bad Company 2 recently (Which runs fine, another thing pointing towards the idle speed too low thing), and while playing that my card reaches about 70 degrees c. I use MSI afterburner to monitor temps in game, and also have a different fan control thing to try to keep it slightly cooler than the default one, also done with MSI afterburner. Ive been using afterburner for a long time with no problems. Also, my card is a Gigabyte HD 6870, encase it matters. So I have to guess that its this idle clock speed is too low thing. So, 2 questions: 1. How do I fix it? 2. Any idea why this decided to start now? Thanks [editline]16th May 2011[/editline] Ok I just went on bad company 2 and it was horrible. I really hope this isnt a permanent problem. Heres the image. [url]http://cloud.steampowered.com/ugc/596937197737238459/3B9AC5DBD22D6C4425DFA68AF066E2A17D5CEEB5/[/url]
Check temps, post results. [editline]16th May 2011[/editline] Also, full specs, including PSU wattage and brand/model.
Temperatures have been fine. Highest is when playing BC2 and is around 70 - 72 degrees c. Ill get my specs in a second, but I think im getting closer. I looked at my clock speeds, and while idle memory and core were 300. I started a video and memory jumped up to 1050, core jumped up to 900 BUT then dropped down to 300 again. So I think the problem is that core clock isnt staying up.
