Ram enquiry my ram in my motherboard H55M-E23 is not operating well so i want to buy Kingston Hyper X Blu 4 GB 1600MHz DDR3 Non-ECC CL9 Desktop Memory (KHX1600C9D3B1/4G),i saw that it is Non-ECC Unbuffered 1866MHz CL9 240-pin DIMM type,i want to know if my motherboard can support it

There are 4 RAM slots. 2 are taken and 2 are free. To upgrade to the maximum amount of RAM you need to place 2 sticks of 4 GB on the free slots.
DDR3 PC3-12800 • CL=11 • UNBUFFERED • NON-ECC • DDR3-1600 • 1.35V • 256MEG X 64 •

OK, I was looking for a solution, but hardly got anything that clarify if it's compatible or not. But what I did find out is that if you install a 1600MHz memory stick, this one will clock down to 1333MHz in order for the MB not to crash. Here is a C/P.

Part #: 2xCT102464BA160B • 16GB (2x 8GB Kit) • DDR3-1600 - 1600Mhz - PC3-12800 • CL11 • Dual Rank • Non-ECC • Unbuffered • 1.5V • 16-chip 512Mx8 • Lifetime Advance Replacement Warranty • This 1600 MHz module is programmed to clock down to 1333 / 1066MHz where the system requires it.

you cant do that. memory is always in PAIRS. The sockets are Colour Coded for each PAIR. two blue two black. the largest may need to be 1st Pair. suggestion: take all 4 out. put 2 largest back in as 1st pair see if pc is ok. then add 2nd pair. see if ok. https://support.hp.com/gb-en/document/c02014355 https://support.hp.com/lamerica_nsc_carib-en/product/HP-Pavilion-p6000-Desktop-PC-series/4079858/model/4123110/document/c01989040 https://www.mrmemory.co.uk/memory-ram-upgrades/hp/pavilion-desktop/p6324uk?search=hp+p6324uk

Kingston has a memory finder. You enter the details of you computer and the site brings up the memory modules that are compatible with your computer. Here is the address of the page.

this will depend on your motherboard
whether you can install a 4 gb module of ram

you will need to select your motherboard from a dropdown list

also on the left will be types of ram ddr2 ddr3...... you will need to select which type you have

If you're not sure if a module is right for your system, use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.

NON-ECC/Non-parity - Most desktop and laptop computers take NON-ECC or Non-parity memory.

ECC/Parity - ECC or parity modules look for errors in data and are most often found in servers and other mission-critical applications used by large networks and businesses.

Unbuffered - Most PCs and workstations use unbuffered memory which is faster than registered memory.

hope this helps you

maximum memory for this motherboard 4 GB not sure about a single 4GB module
Max Supported Memory 4 GB

Supported RAM Technology DDR3 SDRAM

Supported RAM Integrity Check Non-ECC

Two 240-pin DDR3 SDRAM Dual Inline Memory Module (DIMM) sockets

Support for DDR3 1333(OC)/1066/800 MHz DIMMs

Support for up to 4 GB? of system memory

hope this helps

You may have tried to put too much memory (RAM) onto it.
That models maximum spec is:
Memory upgrade information:

• Four DDR3 DIMM (240-pin) sockets
  
• Supports 1 GB, 2 GB, and 4 GB DDR3 DIMMs per socket
  
• Supports Dual channel memory architecture
  
• Supported speeds
  
  • PC3-10600 @ 1333 MHz*
    
  • PC3-8500 @ 1066 MHz
    *DDR3-1333 modules run at 1066 MHz if three or more modules are installed.
    
• Non-ECC memory only, unbuffered
  
• Supports up to 16 GB on 64-bit PCs (DIMMs run at DDR3-1066)
  
• Supports up to 4 GB on 32-bit PCs
  

You can find the specs and troubleshooting help files here

Rather than '1600' Mhz, it's capable of using DDR (Double Data Rate) RAM at '800' Mhz.
The "double" rate provides 2 bits per cycle, resulting in a rating of 1600 for the RAM.

The RAM that you're currently using is '667', not '800' Mhz, rated.
Buy RAM that is rated at '800'.

This motherboard uses DDR3-SDRAM, ECC and non-ECC, unbuffered, PC3-10600(1333mhz) or PC3-8500(1066mhz), dual channel architecture (two sticks at a time), and a max memory of 8Gs.
This are the specs for your ram: 4GB 1600MHz DDR3 Non-ECC
(Kit of 2) Intel XMP HyperX = DDR3-1600
Default = DDR3-1333 CL9-9-9-27
CL9-9-9 1.65V
1.5V
In other words, Yes! This should work just fine. The ram will just run at its default speed of 1333mhz.
