Who told you this was correct for your MacBook?
If you are getting a single beep, out of the Macbook, it indicates it cannot find any RAM installed.

Are you sure they were correctly inserted in the MacBook?

We'll need to know what Model of Macbook you have before we can tell you if those specs are correct.
But it sounds as if you got the wrong type of RAM from KomputerBay. Personally as suggested by Csound1, I would order from OWC(Macsales.com) or Crucial.com. They are high quality RAM providers and are highly regarded and recommended for Macs for their extensive testing.

the computer you have 'may be' a MacBook5.2 (13-inch, Mid 2009) - confirm if that is so.
• How to identify MacBook models - Apple Support
• MacBook: How to remove or install memory - Apple Support
• MacBook5.2 (13-inch Mid-2009) specifications per http://mactracker are as follows:
Introduced May 2009
Discontinued October 2009
Model Identifier MacBook5,2
Model Number A1181
EMC 2330
Order Number MC240LL/A
Built-in Memory None
Maximum Memory 6.0 GB (Actual) 4.0 GB (Apple)
Memory Slots 2 - 200-pin PC2-6400 (800MHz) DDR2 SO-DIMM
Hard Drive Interface 3.0 Gbps Serial ATA (SATA) {Helpful if upgrading to SSD}
Examples of (2) quality reputable vendors of upgrade components:

You would do better with tested upgrade components from reputable Mac-centric vendor
manufacturers who've tried tested the exact spec chips they recommend in specific Macs.
(Re-install original RAM memory to troubleshoot the remainder of MacBook hardware.)
Good luck & happy computing!

Jun 8, 2016 1:26 AMby K Shaffer,So, it would appear you should have checked with more than one source before assuming
the product you were to buy (memory RAM chips) was precisely identified. The information
you provided earlier is what the RAM you bought would (maybe) work in, by specification.
The bus speed is not the memory specification.
I had performed a reverse lookup - with the limited information from the parts you bought.
And provided links in my earlier reply so you could double-check sources of how to
identify your MacBook (to get correct parts, etc) and know exactly what you have.
• How to identify MacBook models - Apple Support
This would have been much easier to determine the parts you need from either of
the two links I provided (Crucial, or OWC macsales) so long as you knew your Mac.
• Examples: (2) quality reputable vendors of upgrade memory components:
http://www.crucial.com/usa/en/apple-memory
https://eshop.macsales.com/MyOWC/
An online identify by serial number lookup can also narrow the field of details to be able to
find more information about your Mac; enough to start looking for parts or system software.
'Mac Serial Number info - Lookup': https://www.powerbookmedic.com/identify-mac-serial.php
Anyway, this should go without saying. Because I have an early 13-inch MacBook that uses
the 667MHz memory chips; but there are so many MacBook builds between 2006-2010.
The only MacBook which uses 800MHz 200-pin RAM is the model I'd looked up by specs.
Please refresh your source of information.
Good luck & happy computing!
