I bought a hd 6870 asus for my pc as an upgrade for my graphics card and a 600 watt smps. The configuration for my pc is core 2 duo 1.86 ghz, 2gb ddr2 ram and a 400 watt smps. The 'computer guy' who's assembling it is telling me that the ram is gone and it needs to be replaced and is only good for windows xp. He is getting BSDs. The ram was working properly before he inserted the graphics card. What may be the problem, is the pc too low a configuration for the upgrade, should I change anything else. The 'computer guy' is telling me to buy 2 more gb of ram. Should I do that, is it necessary?
I'm surprised the computer guy didn't tell you that your cpu is WAAY too slow to keep up with a 6870. It was a waste of money because you'll never see half the performance of that video card with such a slow cpu. The good news is that cpu will run 3ghz no problem with an aftermarket cooler. I had mine at 3.4ghz.
Why he's telling you to get another 2gb when you already have 2gb makes no sense. You only have 2 dimm slots so you can't add another 2gb, you can only replace the 2gb with 2gb. If anything he should be telling you to get 4gb (2x2gb sticks)
He's probably getting bsod's because he has not properly configured the ram voltage.
