New Kingston DDR3 problem.

August 12, 2011 at 12:20:23
Specs: Windows 7
Today i bought new 4gb DDR3 KINGSTON RAM for my pc and now i have problem. No matter what i do i allways get 2 beeps and black screen if i connect new ram. If i put the old one back without new one it works. My motherboard is FoxConn 2A8Ch and it made for small cases. I only have 2 slots for RAMS. I dont know what could cause the problem.
Thanks for help.

The old Ram Specs are:
2GB Dram frequency 533.3 Mhz
New ram specs:
DDR3 4GB PC3 1333 Mhz
Kingston KVR1333D3/4G

Either bad memory, bad bios settings or wrong memory. Not much else.

Not all ram that you might think should work with your mboard will work in it.
The ram must be compatible with the main chipset's memory controller, or with newer mboards, compatible with the memory controller built into the cpu.
- the first ram you listed is probably DDR2 ram. DDR3 ram modules are the same length will fit in a DDR2 ram slot, but the notch on the bottom of it will not line up with the bump in the bottom of the DDR2 ram slot and DDR3 ram uses a lower ram voltage. DDR3 ram won't work in your mboard unless it has one or more specific slots for DDR3 ram.

- your mboard may not be compatible with 4gb modules, or may be compatible with only 4gb modules with certain numbers of individual chips (more chips).

Kingston usually lists Kingston brand name system specific part numbers for their modules for brand name systems. The module you bought is probably not one of those. If Kingston does not list your module part number, then there's no way of knowing if it will work in your mboard - it may work fine anyway, but it may NOT.

If your Windows 7 version is 32 bit.....

The 4gb virtual memory address limit for 32 bit operating systems.
An example of 3gb working better than 4gb in a 32 bit operating system.

See Response 6:

jam's explanation refers to links on other sites:

You may not need 4gb.

Nope they are both DDR3.

"My motherboard is FoxConn 2A8Ch "

Kingston has no listings for that model.
Crucial has no listings for that model.

Did you make a typo ?
If no, then, you quoted the wrong model number, or ....

Is the mboard in a brand name system ?

If yes, it's probably an OEM only model - made only for brand name system builders and there is no support for the mboard model itself on the Foxconn web site(s) - quote the brand name system make and model number

Your mboard cannot use 4gb modules !

If your Windows 7 version is 32 bit.....
see the last part of response 2. You are probably better off installing max 3gb rather than 4gb.
Note that if you mix modules that have different max speeds, the bios, at max, will run all the modules at the slowset max specs of all the modules.

The details....

I searched the web using: FoxConn 2A8Ch

.....and found this...

Hewlett-Packard Compaq 500B Microtower

"Model Hewlett-Packard Compaq 500B Microtower
Motherboard FOXCONN 2A8Ch "

It's an OEM only mboard model !

I searched the Kingston web site with: HP/Compaq and 500B....

Search Results for: HP/Compaq Business Desktop 500B Microtower

Memory upgrades:
KTH9600B/1G 1GB 1333MHz Module
KTH9600B/2G 2GB 1333MHz Module

Standard Memory: 1 GB (Removable) or
2 GB (Removable) or
3 GB (Removable)
(the memory the model came with)

Maximum Memory: 4 GB

Expansion: 2 Sockets

Configurations up to 4GB can be reached using Kingston's 1 and 2GB modules.

NOTE that they list brand name system specific part numbers.
Local places probably won't have those part numbers but places on the web might.

If you don't want to fuss with finding brand name system specfic ram part numbers, don't buy Kingston ram. If Kingston, or any brand, does not list the module part number of ram you bought or were thinking of buying, then there's no way of knowing if it will work in your mboard - it may work fine anyway, but it may NOT !

Other ram manufacturer's or ram distributor's web sites where you can look up which modules you can use in your brand name system model, such as the Crucial web site, do NOT use brand name system specfic ram part numbers.
Once you know which module part numbers work in your model, you can search using the part number and buy the ram from anywhere you like that has it.
