Take the machine and the RAM back to the store to have them show you it working in your machine.
Hi there. I have a problem attaching a new RAM.
First. I have a PC with Asrock P4I65G Motherboard. This MB works with DDR400 RAM. It was working with 2x256MB, and I needed more, so I bought 2x1GB. Two exactly same RAMs. The problem is when I put them both - The PC won't start. The fans start to spin, but nothing happens. It doesn't load anything. I removed one of the cards and with only one 1GB it started. Then I removed it and returned the both 256MB cards, and it started again, then I removed them and put the second 1GB and it didn't start again. I thought the RAM is not working well, but there was no problem with it when it was tested in the store I bought it from. So I don't know what the problem might be and it doesn't want to work.
Second. Another PC (with the same Motherboard) was working with 256MB RAM and I wanted to increase it. I removed it and attached the 1GB I mentioned above (the problematic one) and it didn't start. Then I tried with 512MB and it didn't start again. I tried with the 256MB what was working on the previous machine, but it didn't start again.
So I think that there have to be something specific that have to be done, when I put new RAM, that I don't do right. How come on same type of MBs the RAM is working on one of them, but it's not on the other one? I tried with CMOS BIOS RESET, but didn't work. What do I do wrong? Could it be something with the MBs or the RAMs? I'm not sure, but doesn't DDR400 means that it works on 400mhz? When I turn the PC on (with the working 256MB RAM) and enter BIOS, it shows that it works on 266mhz. I hope someone can help.
