RAM comparation

Hi,

What should match on Kingston RAM labels when adding extra RAM ( revision number, part number...)? ...not in a kit.

The usual way is to buy an identical stick from Kinsgston...just use the model number KVR80002SS6/2G

We have many Kingston RAMs are different in point 3 and 4. What do they mean? Should they match?
John TsioumprisSoftware & Systems EngineerCommented:
I don't think these are of any significance
The memory should match :
Type : DDR3, DDR4, DDR2....etc
Timing : 1600,1800,2000...etc
Latency : 11-11-11, 9-11-16...etc
Voltage : 1.5V, 1.35V,....etc
If the part number is the same then the memory should work fine.....only if you are overclocking you need to dig deeper in order to get sticks from the good ones ...(production LOT...like the CPUs)
To be certain ...use a machine as a testing bed....install sticks one at a time....load windows --> CPUZ should have all the info you need...write it down...
Find the matching ones
Then load Memtest+ for each stick and let it run a couple of hours to check if they get error-free
For  Pairs (after Memtest)  load Windows --> IntelBurn...try to use maximum allowed settings....let it run for 10 passes...if its Ok then everything is good

Since you said, you have a lot of KVR80002SS6/2G already there, with slightly different numbers in section 3 and 4, these memory modules will definitely work well. These numbers are internal for Kingston to know, but for customers it's irrelevant. KVR80002SS6/2G is the only important thing.

Does anybody know what points 2, 3 and 4 actually mean?

As stated, you only need to pay attention to the part number.  This is your answer as stated by others and restated by me.

2 is a revision number.

As for the other numbers, the fact that they are not common (as indicated by a google search) should indicate they are not important.  If they were, and they needed to match, you would find a lot of references to them.  As it is, searching for 3, you get "Your search - kingston 0000005212769 - did not match any documents."  Searching for 4, you get 2 results but neither page has "akmk1621168" actually on it... So, a reasonable person will surmise that this number is unimportant to the question as well.

One or both unidentified numbers COULD be used as a serial number or a tracking number indicating what plant it was manufactured at, who inspected it, when it was made, what equipment in the plant was used, etc.  Things you don't care about.  At least, you shouldn't in probably 999999 cases out of a million.

If this is TRULY important to you, even though several of us have already stated it shouldn't be, then I suggest contacting Kingston directly.
