Multiple part numbers for same part?

I was looking into buying memory from Dell, and I noticed they sell what appear to be the same memory stick under four part numbers.
The Manufacturer number is the same, SNPFYHV1C/4G, but Dell's part numbers are A6049771, A5596704, A5327546, and A5327547.

Are these all in fact the same memory module? If so is there a point to having four part numbers (other than to confuse people)?

Can you post the Dell computer you have that is needing memory?I will then take a look at the memory for your system and let you know the correct part number.

Thank You,

I've already ordered A6049771 for my Vostro 3460.

 

You are better off to purchase from a 3rd party, such as Kingston, Crucial, etc because when you have issues it will be much easier to get services.

 

I just ordered Adata 8GB kit that was certified for Sandy bridge and called it a day. no issues with the ram and the machine is fairly quick

 

As part of my campaign to make sense of my APPAULING EXPERIENCE with Dell over the last year, I have been investigating and talking to former Dell employees:

Dell has multiple part numbers for the same part because they use parts from different manufactuers:

How it works:
(1) Dell will purchase the cheapest parts available for a system at any given time based upon fluctuating market prices FROM DIFFERENT VENDORS.
(2) Any given system with the same specification and model number is likely to be comprised of some of the same and importantly some different totally different hardware parts from totally different vendors.
(3) Dell does this to maximise PROFIT, to buy cheap and sell high.
(4) Many machines are sold with only a one year warranty, especially consumer machines

Thus, the machine reviewers in magazines reviewed may be a substantially DIFFERENT MACHINE than the one they sell to you.

This is why, on these forums, many people suggest for the same SCREEN SPEC some screens are great and others awful, and when they investigate, they discover DIFFERENT MANUFACTURERS and non standardisation. This means there are HUGE VARIANCES of parts inside Dell computers, and Dell staff are encouraged to suggest they don't know about problems that have been reported en-masse to them:

Across this non standardised hardware, Dell doesn't properly exhaustively comprehensively test ALL COMBINATIONS and this can create LOADS OF TECHNICAL ISSUES and compatibility issues.

Dell Employees, please can you make an official detailed statement to clarify for everyone my expressed understanding cited above, it's accuracy and implications.
