Hi, I recently purchased a 512mb memory card for my HP Pavilion a714x which had a 512mb already in it. I read my specifications on the HP website and they were: Memory Installed 512 MB (1 x 512) Maximum allowed 1.0 GB (2 X 512 MB) Speed supported PC2700 MB/sec Type 184 pin, DDR SDRAM DIMM slots Two Open DIMM slots One The memory card i bought from newegg was this Brand pqi Series POWER Series Model MD3412UOE Type 184-Pin DDR SDRAM Capacity 512MB Speed DDR 333 (PC 2700) Cas Latency 2.5 Voltage 2.5V Heat Spreader No I think it should be compatible, but whenever i try and install it i cant really hook the two ejector buttons on to the card, The card it about half a centimeter or so bigger than the one installed already. I tried going to BIOS screen after i had the card in there, and it didnt recognize anything. The sticker on the stock memory card says: 512mb DDR, 400, CL3 Any suggestions? Thanks in advance.
