Heya

Basically a long time ago I made a series of threads regarding flickering lines during games, I got a GTX460 768mb and Just saw a similar thread a moment ago.

Basically it was a long and painful process, I RMA'd the cards 2 times, swapped PSU, swapped monitor, swapped adapter, and it stayed same. Overclocked and on stock. When I turn V.Sync on it fixes it in most games to some extent but not completely.

Some person said if mem/shader clock is jumping or something, that might be the problem, so I left Afterburner on and played BC2 for a moment, then I saw this

Look at shader clock, something not right there, or is it ?
if so, whats causing the problem ? Reminder: I RMA'd the card 2 times and got new one twice aswell.

This isnt that big of a issue. Only thing I havent tried yet is is a HDMI adapter, but my monitor doesnt support it I dont think. or Is there a cable that connects monitor with DVI and card with HDMI ?

Well anyway, suggestions ?
 
Also, buying a GTX560 soon so Ill see if that will fix it if theres nothing else. Not big of a deal I guess anyway.

Rest of my specs are Phenom II X4 965

Coolermaster GX550W

G.Skill 4GBDDR3

Also, forgot to mention in first post, I tried my friends corsair ram aswell.

EDIT: Clock/Memspeed seems to have been jumping at those times although I didnt notice any FPS drops... so how can this be fixed ?

Gpu core clock there is fine, you'll often get a few ups and downs as you load a game, go in menu, it will drop to 2d clocks as it does a loading screen or something and back to 3d afterwards, you can see that when the gpu load really went up, which I would assume is in game, then the core clock was solid at whatever it was, that last bit will be where I assume you alt tabbed out of the game back to windows which will again drop the clock back.

Its pretty much always memory though that causes the flickering, but thats a quite distinct type of flickering, it may/may not be visible if you just sit in windows and change the memory clock a couple times in afterburner, try the idle 2d clock then whack it up to full speed, hopefully you'd get an idea if its the same kind of flickering.

Worse with gddr5, to a degree, is its "self fixing/regulating". If gddr 3/4 over heated it would either error and crash, or downclock but you could see that with a monitoring app, gddr 5 if its unstable will only internally clock down to a stable speed, for stability thats great, but you can't see the memory changing speed.

Now 99% of the problems I've seen with flickering are just incorrect UVD profiles, or something like a game not going to full 3d speeds in a windowed game. The possibility of duff memory is just an outside shot, you could run a lower than normal clock speed to see if that fixes it(assuming afterburner isn't showing the memory changing speeds).
 
Hey mate, thanks for the help.

As I said, I tried friends Corsair memory aswell. I guess this can be ruled out.
I also ran everything at stock, no go.
 
Sigh, I dont think a GTX560 will help this as Ive tried the gtx460 in friends PC and it was fine. one thing left is the mobo... but how can it produce such lines ? tbh id say my first bet was GPU and memory, then PSU, Monitor. All ruled out.
 
Ok, ive been reading up on this again and a lot of people suggest page distortion, and turning on V.Sync to get rid of this.
Ok, but in that case, how come at my friends house we tried my monitor and without vsync, and his monitor without vsync, and we didnt get anything but at home I do ? Cant be the monitor surely can it ? must be something inside that PC.... Im not sure if a motherboard can be the issue, I checked for leaks etc, didnt notice anything.
 
Yep, OS reinstall about twice. Also reinstalled drivers multiple times. Nothing helps.

I keep thinking its something to do with the monitor, but like I said its been tested and nope... was thinking it might be refresh rate issue.

Well now it has to be either Mobo or cables which ive tried aswell.

The mobo is quite cheap asus 760 socket one, I bought it for like 35 quid from Ocuk... that might be it too..
 
:D

Too late for RMA I think, Im just gonna buy a new one. Im also debating if I should buy a new case aswell, I dont think a 560Ti would fit in there. Although my GTX460 from asus fits in no problem.

Hmm, how would I put this..

(Card) - - - - - - - -- - - - -----------)

If you put fingers on (Card) till the end, thats how much space I got.
 
Shouldnt be that big in that case. What about 6950 ?

Although now im thinking if I should buy a new mobo first. What do you think ?

Edit: This is the mobo I got

Asus M4A78LT-M
