Hi I'm in the process of upgrading my p.c to potentially use it with my projector. I have a question about ram, i know I need dimms and my processor is an athlon 650. I have been offered 128mb of pc133 ram for v.little money by a mate. I understand the bus speed on an athlon 650 is 100 mhz so I believed I should use pc100 ram to match this.Can I buy and use the pc133 ram in my computer without mucking it up? Hope someone here can help me as an answer by monday morning is useful. ( I know my motherboard can support pc133 dimms but I assumed that is only if you have a faster athlon ). Thanks.
