Having problems with your Dell OptiPlex GX150 SF PC Desktop ?

I installed another 256 of ram, for a total of 512, but the computer only says i have 256 what can i do.


Answers :

Remove both RAM modules.
Just install the new one to see if system can see it.
This will tell you if the new module is ok and can be seen by your system.
It is rare but you may have gotten bad RAM.
If the system sees the new module then power off and add the old one for total of 512.
When the system powers up hit DEL or F2 or whatever key gets you into CMOS.
Change something harmless in CMOS like add a minute to the clock.
Save and exit cmos. If that doesn't work make sure the new memory is an EXACT match to the original.


I've done this before in my early days. Make sure that the memory is exactly the samme type as the original one, and make sure your motherboard can handle the extended memory. Check in system properties for all this info.

I am working on an HP Pavillion a1220n Desktop and I am getting different bootups each time.
