Hello everyone, i am using HP Pavilion p6255d and i want to upgrade the RAM. my current installed ram is PC3-10600 MB/sec(DDR3 - 1066mhz).. here are the compatible ram on my desktop

PC3-10600 (DDR3-1333)
PC3-8500 (DDR3-1066)
PC3-6400 (DDR3-800)

,someone gave me zeppelin 4gb 1333mhz . but when i remove my current ram and use this zeppelin ram when i open the desktop i keeps beep sound. first 1 beep is short and second is 1 long beep. what should i do? does my pc can support only 1pc of 4gb ddr3 1333mhz or it only supports 2pcs of 2gb ddr3 133mhz?

because when is use zeppelin 4gb ddr3 1333mhz i still have one left slot for my ram.

Thank you in advance. i hope someone will help me 🙂

Supports DDR3 DIMMs only
Dual channel memory architecture

Non-ECC memory only, unbuffered

Supports up to 4 GB on 64-bit PCs
Maximum memory only if using 2GB DDR3 DIMM modules

so yes it appears to be 2 * 2gb only
