Gpu over clock

[8721markc]

I have a ASUS GeForce GTX 570 1280MB (ENGTX570DCII2DIS1280MD5) Graphics Card
Can it be over clocked as I was on fsx on high setting and get a message saying there's insufficient memory

I have a msi 970 g46 motherboard, 16 gb g skills ram, 2 128 gb Ssd 1 1tb hd 2x 320 gb hd psu cors air 550 w,

I bought the gpu from e bay didn't receive installation disc and was wondering if it can be used with gpu tweek, or could the problem be limited to the fact it has 1280 memory?

FSX is massively CPU bottled, so overclocking your GPU will make almost no difference.

You might have to change the settings for your virtual memory. I got the same error playing Star Wars: The Old Republic (also CPU heavy) and increasing the values solved the issue.
