Yes, this is not the correct place for such questions. While I don't mind helping people out with hardware questions, please don't post them in this BenQ forum. You say that your computer needs memory in pairs. Are you still running an older system that requires the use of 30-pin SIMMs (single in-line memory modules)? I haven't seen one of those in quite a long time. Anyhow, if your motherboard uses SIMMs, then I would not upgrade that particular system. Rather, I suggest getting a whole new system. Computers of that age just aren't worth upgrading that much. Spend your money on a new PC. That's my opinion on this matter.
Again, any more questions of this nature belong in the hardware forum like pcdoc told you. :iagree:
