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.

What are the spec of the 8GB kit/modules?

 

[brublag]

The spec says:
Supports the following configurations:
8192-MB total system memory (4096×2; not supported on a 32-bit operating system)
4096-MB total system memory (4096×1 or 2048×2; not supported with Windows® 7 Starter OS)
3072-MB total system memory (2048×1 + 1024×1; not supported with Windows® 7 Starter OS)
2048-MB total system memory (2048×1 or 1024×2)
1024-MB total system memory (1024×1; not supported on a 64-bit operating system)

Can you list the part numbers of the RAM modules

 

[brublag]

I can but I'll have to remove some covers to do so - I will post when I get time. Both sets of memory are DDR3 1333 MHz?

First and foremost, are you sure that you have a 64bit OS installed? 32 bit OS will only ever read 4gb of ram.

Secondly are you sure you got the right sticks for your laptop.
Your Compaq requires low voltage ddr3 memory that is 1.35v and CL-11

The part number on each of the 4GB memory sticks is: HMT351S6BFR8C - H9 N0 AA. The OS is 64 bit. I can also post the part number of the 2 GB sticks if you like. Thanks

Yes it is a 64 bit OS. When I Google the part number of the 4GB memory (HMT351S6BFR8C) the new egg website says it's 1.5 V. Is that too high?

 

[boosted1g]

That is 1.5v chip

Your laptop needs 1.35v DDR3L memory.

(some PCs can handle both, some cant)

I looked up the ones installed in the CQ57 and the specs that found say that they are 1.5v?

What are the 2gb sticks you currently have?

I'm assuming that you mean the part numbers? They are
EMB2GO481-13HC CNG & HP594908-HR1-ELFE

what is the rest of the model number of that CQ57

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

There may be specific differences between them.

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.

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?
