I own a Compaq Presario SR5333WM with Windows 7 installed

 

For some reason, the system only posts on 1 stick of ram. I've tested both DIMM slots and DDR2 Ram sticks, and both seem to be functioning normally. This issue comes when I try to install the 2nd stick of ram; As soon as I do the system refuses to post. I've tried reinstalling the bios, but to no avail. 

 

Please help

Occasionally a system will be unable to get two sufficiently dissimilar modules to work together - what brand and specification are the DIMMs? Did the system previously run the two together satisfactorily, or are you trying to add RAM?

 

When you say "reinstalling the BIOS", what did you do?

Indeed its a common in windows, the ram sticks must be identical

The best is to have identical modules, particularly to ensure dual or triple channel operation, but if they are sufficiently similar to operate successfully, that's what is needed.

My DIMM's are identical Micron 1Gb DDR2 ram. To answer your question @platypus, I reinstalled the bios by reflashing it using winflash

Also yes, the two ram sticks have previously worked together

So the BIOS is updated to a newer version?

 

If all the possible combinations of fitment:

 

i.e

 

Stick one in slot 1 alone and then in slot 2 alone, then stick 2 in slot 1 alone then in slot 2 alone, all work, but

 

Stick one in slot 1 with stick 2 in slot 2 doesn't, neither does around the other way,

 

you're left with the need to prove whether the problem lies with the RAM, or the rest of the system.

 

You're pretty much left with a process of elimination, and I think the best possibility would be to get to test the RAM in another system and see if the same problem occurred. It wouldn't 100% prove the issue if another system could use it OK, but if it also failed in a second computer, that would be pretty conclusive that something has happened to make the DIMMs no longer compatible with each other.

Restart your computer while tapping the F10 key that should open the system bios and then see if both memory sticks are detected and show in bios.

 

If both sticks of memory appear in bios than you may have a OS system problem.

@The-Toolman When both sticks of ram are in the computer, the system doesn't even post.

My mistake as I failed to catch that and it appears post #7 is the next step.

will a single stick work in either slot?  maybe the 2nd slot is damaged.

 

look at your ram slots, see if the second slot is damaged.

So I've finally tested new ram in the PC, and I've narrowed it down to the PC itself having the problem, I doubt the pins are bent, because individualy, a single ram stick works in either

funny, this jogged my memory.  i had the same thing happen many years ago....the reason?  no idea.  i had to use one ram stick.  i cannot recall exactly what i did.  but after many resets i fiinally got the 2nd stick to read.  wish i could remember what i did.  (it was an amd dfi lanparty motherboard...)

 

clearing the cmos is a stock standard procedure.  check yr motherboard manual to do that if you can. (if you havent already)  or just take the motherboard/cmos battery out for a few minutes then put it back in.

 

id suggest hitting it with a hammer but that doesnt usually work  :lol:
