wow, u've pushed memory greatly, however, i think the more is gained by pushing the core.
my games crash when i get core at 910.

well i'm kinda a beginner still

does less memory = more core oc?
and could someone tell me why my screen goes black but the pc still runs when i go past 880 coreclock or change the voltage

no. as far as i know, though someone may think otherwise. my card gets unstable/artifact as soon as i get core past 910, regardless of the memory clock.

as for ur screen i'm not sure. it may be the case that ur card simply can't handle anymore than 880.

but it's a bit weird because I've looked at reviews of the same card and they could reach 9xx/10xx with theirs. (with a slight voltage bump)
and as goes for the artifacts care to explain more detailed what it is cause I've never ran into any the only issue i have is some weird white lines that appears on my screen when i go on a black wallpaper but it doesn't seem to change whether i use stock clocks or oc

i'm not sure about those white lines on the black wallpaper but if ur using a 21.5+ inch monitor i assume ur talking about the light leakage which is relatively normal for the widescreens...presuming those white lines are hardly noticeable of course. if they are strongly noticeable then u should take ur monitor in a shop.

artifacts are abnormal objects, of any shape and color which appear on screen for a very short period of time. normally, they blink frequently. that's a standard sign that ur card is overstressed.

edit:
and yes, ur right, Barts core (used on 6850/70) should be able to push beyond 9xx MHz.

thank you for clearing that up for me it's been a real headache with the lines.
it's most likely leaking since it's almost impossible to see if ur not "looking for it" and it's a 1600x900 screen.
so i guess my card's haven't been over-stressed yet

1008mhz/1140mhz on stock voltage.
Barts core loves to be keep cool. If you can keep it below 75C you should be geting high 900s. If you can keep it below 60C you should be able to get 1ghz.
Before I went on to using Antec 620's to cool my cards they could only do 940mhz at 78C.

Yes, the Gigabyte version was meant to have it's own program for voltage change, but it was never released. I know 'cause i was going to buy it when i got my first card and i emailed support asking about the voltage regulator. So that's a no go. Keep the memory at stock and keep pushing the core, in some cases it does allow you to push the core more. - Also that sometimes the memory is passively cooled.

Read below, try a voltage bump too. (It could also be heat related)

Yes, i see alot more gain by pushing the core. The memory on these cards is passively cooled sometimes, so i just tend to leave it at default to save worrying about them burning out.

It means your graphics card driver has reset... Which means it's unstable. rolleyes.gif
