I've got a PIII 450 on a Abit BH6 1.1 with the SP Bios update. I've got 3 sticks of Kingston PC133 ram. Here's my problem whenever I run it with 768MB of ram the computer always wants to crash but if I remove one stick and run 512MB it runs fine. Why is this? On the abit website it says the motherboard can handle 768MB. Any input would be a appreciated.
