Laptop memory does not see 8 GB

[brublag]

I have a Compaq CQ57 and the specs say that it can handle up to 8 GB of memory but when I install 8 GB using two 4 GB memory sticks or one 4 GB stick it will not boot. The two 2 GB memory sticks that are being used in the CQ57 will work in a Dell E6510 that I have. Specs say that the memory should be DDR3 1333MHz which is the same for the Dell E6510. Any advice or solutions are greatly appreciated.

I see 584037-001 after a barcode on the Windows certificate on the back and if I add that after CQ57 and Google that one of the responses is this link https/www.notebookcheck.net/HP-Compaq-Presario-CQ57-Series.68934.0.html which shows a few different CQ57 specs. The only places that I see CQ57 is the lower right corner of the display and in the bios. Computer properties shows 'Presario CQ57 Notebook PC'. I don't know where else to look.

Just google Compaq CQ57 and you will see how the results have extra digits behind them.

There may be specific differences between them.

I realize what you're saying - I'm saying that I cannot find anything but 'CQ57 Notebook PC'.

I see, well if your old chips where 1.5v then your new 1.5v chips should work as well.

Are the new and old chips the same speed and cas latency?

They are the same speed but I don't know about the cas latency. How do I find that?

The are both DDR3 1333 MHz.
