I'm looking too see if anyone else has had this problem, not how my computer sucks, my video card sucks, and now i dint under stand what I'm doing.
i thank you all for the help you have given me info I never knew I didn't know that I'm a clueless idiot who has never done this before (yet i have), or how my video sucks and i should go beg mommy for a new one.
if you have to add more to this conversation then do it in a poilite friendly way, if not the door is right there.
Quick lesson on memory, video or system.
All memory is not created equal, even in the same batch just as in CPU's
To sort out the better chips they test them in a process known as binning the memory (name comes from sorting the memory and putting in separate bins)
The best example is in system memory. 1600, 1833, 2166 memory can all come from the same batch. Any memory above 1600 is really just overclocked 1600. There is no real standard above 1600. Since only the best of memory chips can be clocked at the higher speeds they cost more, not so much due to the construction costing more but the sorting and rarity of chips able to do so.
Then there are different manufacturers of the chips themselves.
Samsung, Hyundai, Indellux, Micron etc.
Some produce better chips than others.
Micron for one is known to usually overclock better than most.
Hyundai also has made some good chips.
Then there different plants in different countries from the same manufacturer.
Some plants produce a higher quality product than another.
Thats why there are codes on the chips themselves just as in CPU's
Now add video cards manufactures with different motives. The cheaper priced ones use cheaper priced materials.
How do you think they can sell the cards cheaper?
When you overclock system memory past what it can handle it either stops booting or starts blue screening. Keep doing it enough and you either kill the memory or the memory controller.
With video memory it starts producing artifacts, keep pushing it and it will start artifacting at even stock speeds as it gets degraded by to much heat. Feed it with to much voltage such as a bios mod or an overclocking app and it compounds the problem.
Video cards also have a memory controller and voltage regulator. These can also be damaged. Kind of like to much back pressure in a fluid pump can destroy the pump by overheating.
Not bashing your beloved HIS, just saying they are a cheaper priced card for a reason.
Your seeing artifacts because the memory on your card cant handle what you are asking of it.
Ack Ack is correct. Games and certain benchmarks do not stress components like programs that are designed to test stability.
Herein is the reason it runs some programs and not others.
A standard in overclocking is that a component must be able to run the overclock stable for a minimum of 12 hours pushed to the max before being considered a stable overclock.
CPU's are much the same. Such as my I7 2600k cpu, I can get it to boot to 5.0 with enough voltage, but not stable for 24 hours even with massive cooling. Heck not even stable at all when asked to do much. It will however run 4.7 24/7 with a lower acceptable voltage.
It is however one of only 30% of CPU's that will handle 4.7 24/7 stable. So im ok with it.
Theres lots of reading out there if you want to learn properly. Overclocking properly in small steps and constant testing can be done without killing components.
Enter at own risk.
Hope that helps grasshopper.
