Installed additional RAM on HP P6531p desktop, computer freezes on start-up. Using Kingston DDR3 SDRAM DIMM PC3 10600 @ 1333mHz 2GB. Computer starts and runs fine with 2 sticks installed, but freezes with four.

every PC has a spec. 2012 PC, it seems. (carbon14 dated) lol
and memory is the most complex of all.
The rules are .
so lets read your manual together, ok?
btw Gateway died and is now ACER.com (same with packard bell)
i looked in Acer, and zero. (is this thing a relic?) y/n no, acer search engine sux. big time, so... Im forced to use google on to acer.com
a DESKTOP PC. the spec page shows....

• DDR3 SDRAM
• Memory Speed 1333 MHz
• Memory Specification Compliance
  PC3-10600
• Technology
  DDR3 SDRAM
  
• 16 GB max ram
• DIMM 240-pin

that was the first google hit, on spec. google is our friend.
not mine but yours. I use real manuals.
DDR3 in DIMM form factors, come in varying heights,
by RAM size and what chips are there, ok?

if you wiki dmm you see all that. full spec. on DIMM
ive never heard a tech ever in my life ask Physical size.
this perplexes me, why this is asked. ok?
the length is fixed, no variances , only height, so my wild wild guess
is you are afraid of hitting gamers grade CPU heat sink, that it?

here is the wiki page, it shows all you need to know.
the PC can not use all DMM3 made, it must be fast enough,.
PC3-10600

https://en.wikipedia.org/wiki/DDR3_SDRAM

the spec is here.

why not attempt to buy the DIMM at the top maker kingston.com
and see the sizes spec there, no 2 are the same tall.
some memory chips are huge or there are 2 rows tall.
that is all allowed.
30mm is common sizes. tall.
like so.

https://www.kingston.com/us/memory/valueram/desktop?TotalCapacity=2&Memory=DDR3&ModuleType=DIMM

click sheet
1st stick I see is 30mm tall.
there are lots of makers and lots of sizes of DIMM.
I cant review them all but you can.
acer runs a gateway site , seperate.
here is your full manual.
RTM. but , oddly does not cover ram,ddr,ddr3, or memory at ALL.
wow. what a trash PC, and maker, buy dell by HP, never acer.
http://www.gateway.com/gw/en/US/content/drivers-downloads
that is all I can dig up,, I'd sell it !

You can upgrade to 2GB.
(1024MB.
512 MegaByte + 512MB = 1024MegaByte
1024MB = 1GigaByte )

It is DDR Sdram.
(Double Data Rate Synchronous Dynamic Random Access Memory)

It is also SO-DIMM, as used for laptops.
(Single Outline Dual Inline Memory Module)

http://en.wikipedia.org/wiki/SO-DIMM

There are 200 gold plated contact pins. 100 on each side,

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

Note the Locating Notch on the bottom, and how it is off to one side.
Note the Side Notch on each side.

There is a Locating Lug in the bottom of the ram memory slot, for the laptop.
The ram memory module must be turned to the Locating Notch lines up with the Locating Lug.

There are spring clips on each side of a ram memory module.
The tops of the spring clips are eased to the outside.

This allows a bump, or protrusion on the spring clip, to come out of the Side Notch.
When the ram memory module is ensured to be seated correctly, in the ram memory slot, the spring clip 'bump' will be in the Side Notch.

A laptop ram memory module is removed AT AN ANGLE!
NOT too much more than the angle it is in, when installed in the ram memory slot.

After the two spring clips are eased out, the ram memory module will pop up a little bit.
Slide it out AT THAT ANGLE.

If you it up to a straight up position, you will damage the gold plated contact pins of the ram memory module, and the contact pins in the ram memory slot.

Damage the contact pins in the ram memory slot, and you are looking at motherboard replacement.

Everywhere on the ram memory module is the BODY, except for the gold plated contact pins.
Handle the ram memory module by the Body.
The Body is coated with a see-through protective plastic.

Refrain from touching the gold plated contact pins.


[ DDR Sdram IS DDR1. Double Data Rate Sdram.
DDR2 Sdram is Double Data Rate 2 Sdram.
DDR3 Sdram is Double Data Rate 3 Sdram,

2) http://en.wikipedia.org/wiki/DDR2_SDRAM

3) http://en.wikipedia.org/wiki/DDR3_SDRAM

It is the Technology used, not referring to the size ]

DIMM for desktops, Dual Inline Memory Module
SO-DIMM for laptops.
Single Outline Dual Inline Memory Module.

You need SO-DIMM, with 200 pins, and it's Frequency Rate, ('Speed'), is rated at 333Megahertz. (333MHz)
That is PC2700.

If the manufacturer stated this maximum, there is no way around it. Get an SSD for a large speed improvement. As for the DDR3 vs DDR2, this is also set in stone. Sorry!

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

The Samsung N150 Laptop comes installed with 1GB of Memory and can be upgraded to a maximum of 2GB Memory. This computer has 1 (one) SO-DIMM memory slot, so to upgrade to 2GB of RAM, you will need to replace the installed RAM module with a single 2GB PC2-5300 DDR2-667 200pin SDRAM SO-DIMM memory module.

(PC2-4200) correct 533MHz you can go up to 2GB max, they should be matching ...non buff, non registered, no ecc
Modules must be installed in pairs for Dual Channel mode.
This tell you what you need, I am not sure why.
It would seem to me if they were equal in all aspects ...???

Hello,

Located here is the actual specifications of your W3052.

http://www.emachines.com/support/product_support.html?cat=Desktops&subcat=W%20Series&model=W3052

The DDR means "double data rate", SDRAM is "synchronous dynamic random access memory" and DIMM is for "dual inline memory module". These are the way manufacturers describe the specific speed, type, and packaging of the memory. You need to get the correct combination for your computer in order for it to function properly. The PC2100 is NOT correct, at the very least it will slow your computer down, and possibly will not work at all. You should use PC2700.

If you wish to add another 512MB taking your computer to 1GB total, then you only need 1 module, a 512MB, like the one that came in the computer. Do not purchase a 1GB module expecting it to work properly with the one already there. It probably won't. If you want to max out your computer's memory taking it to 2GB, then you will need to purchase 2 each 1GB modules, and remove the existing 512MB module.

When you go to the computer store, you ask for either "one five-hundred-twelve megabyte, PC2700, DDR, SDRAM DIMM memory module" or "two one-gigabyte, PC2700, DDR, SDRAM DIMM memory modules".

The part numbers from, Kingston, one of the major add-on memory makers are shown here:

512MB = KVR333X64C25/512
1GB = KVR333X64C25/1G
