Help adding ram please.

[anderson S]

I have Asus M11AD and yesterday i wanted to add another 4gb of ram so I got the ram and put it into the second ram slot in my pc. Then when i turn on my pc it works fine for about 10-15 minutes and then reboots. I would be glad if someone could help. thank you in advanced.

First thing: 3 GB is a strange amount to add. How much RAM do you have total, and what configuration is it? When working with RAM you typically want to work in multiples of 2 (2, 4, 8, 16, 32, etc).

If the new RAM that you bought is a different frequency and CAS timing than your existing sticks, then you may run into some serious system instability problems. I think this is probably the case with what you've done.

If your PC is 32bit, it won't recognize RAM more than 4gigs.. also there are chances that one of the sticks is faulty.. Happened to me.. you must test and use the sticks individually to identify the bad stick.. once identified, you can claim warranty on it..

im sorry i meant 4gb. My computer has 4gb ram installed but i want to add the other 4gb ram

 

[anderson S]

and i have windows 8 64bit installed

Aright, is it identical RAM? Same manufacturer, same speed (e.g. 1600 MHz), timings, etc?

 

[Entomber]

Your second 4GB stick of RAM should ideally be identical to your first, or you could damage your system.

and i have windows 8 64bit installed

in that case,

try testing them one by one.. chances are that one of the stick is bad..

before that, what is the MHz of the stick?? does your motherboard support it??

just post the model of your motherboard and the RAM here..

 

[anderson S]

I do not know, i am very new to adding ram

 

[Entomber]

In short, you can't just buy any old stick of ram and put it into your computer and expect it to work properly. It's probably the case that your two sticks of ram have different timings and latencies, and they are not working together properly, which is causing your system to shut down unexpectedly.

Every stick of RAM has a rated speed in MHz and timing in CL, and if you want to install multiple sticks of RAM in your computer they must match in speed and timing.

Pull the DRAM and let us know the model #s and we might be able to get them to play nice together

 

[anderson S]

which one is the model number?

 

[Tradesman1]

Probably the longest number

 

[anderson S]

The one im trying to install is-W1333UB4GH

And the original one is-AQ2L16BC4R1-BR1S

 

[Tradesman1]

Let's try it a different way, try booting with a single stick in slot one, if you get to Win run CPU-Z (a free utility program) and look in the SPD tab it should show the model # next to the Part Number pane, then try the same with the other stick

 

[anderson S]

it only shows part number

[Tradesman1]

Have you got the stick in slot 1 (closest to the CPU) and CPU Z showing Slot 1 in the upper left corner of the SPD page?

 

[anderson S]

yes

 

[Tradesman1]

May just be low end value type DRAM anything on the sticks showing 1066, 1333, 1600? one of those may be the model #

 

[anderson S]

yeah the one i want to add is W1333UB4GH

 

[Tradesman1]

Try clearing the CMOS then put that last stick you mentioned into slot 1 and the other in slot 2 and see if you can get to BIOS, see if you can change the DRAM voltage, if so raise it to 1.575 or so

 

[anderson S]

I have tried to do that but I canot find where to change the voltage in the BIOS

 

[Tradesman1]

Am guessing it's a locked BIOS, was hoping not and that the sticks might work off the CMOS reset, which often can with 1333 and under, sorry
