Motherboard doesn't want to see less than 6gb

[I_See_Stars]

Hello.
The problem is, when I start mining with 4gb everything is crashes (more like freezing  ) and nothing happens. I tried to add 2gb else of 4gb and everything is fine. But for 2 miners and win 7 4gb is pretty enough because taskm shows 2.5gb usage. So I have to suffer with 4gb in my PC instead of farm 6gb. Yes, 2gb is not such a big problem to buy but I hope there is a way to solve this trouble.

You'll want to repost this in the gpu mining section for Alt coins.

However, you might want to make sure the ram frequency is supported in the BIOS on the motherboard.
(Not all ram is created equally, and some have higher speeds that are labled on the ram sticks; ie 1866)
While you are in there look to see if it has a pre set limitation on the ram slots, if so change it to your
liking.
