Hi I recently bought 2 x 1gb of pc 3200 184 pin (LD 400 MHZ DIMM CL 2.0 and it wont work on my PC. The memory that is in my machine is just the same as far as I can see? It fits perfectly! I have a Compaq SR 1719 could anyone tell me if this is compatible or am I doing something wrong or is the memory faulty? Thanks

Not sure I bought it from ebay, the person I got it from told me it was compatible with my machine before I bought it, I just want to make sure it is the wrong memory or if its faulty before I return it

refer to the manufacturer to confirm you are using compatible memory....as a general rule, e-bay sellers are not a viable resource.

there are several flavors of the SR 1719 so be sure to select the correct one....here is a link to the specs for the SR1719ES

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00...


from that page....

Memory
Component Attributes
Memory Installed 1 GB (4 x 256)
Maximum allowed 4 GB* (4 x 1 GB) requires the replacement of the installed 256 MB DIMMs

*Actual available memory may be less
Speed supported PC2-3200 MB/sec
Type 240 pin, DDR2 SDRAM
DIMM slots Four
Open DIMM slots None


Question....are you leaving any of the original DIMMS installed or are you removing them all and installing only the two new DIMMS?

Hi yes Ive taken out all the dimms and installed new one at a time. When I turn on the machine it beeps? and nothing happens just a black screen. My machine is compaq SR 1719uk . Installed just now is 1 GB PC 3200 DDR 400 MHZ DIMM just the same as what Im trying to install, so not sure at all why it wont work??? Ahhhh

They most likely don't work because they don't meet the specs. All compatible modules seem to be CL 2.5 or CL 3.

maybe I am mistaken but that shouldn't be a problem...the CL 2 chips are faster than the CL 2.5 or 3 so they should have no problem slowing themselves down to a 2.5 or 3 latency.....

Unfortunately most Compaq systems only accept memory modules that meet the specs. They don't try to adjust them; therefore it's much better to buy modules that are certified to be compatible by the manufacturer.
