[dba-Tech] RAM Terminology

Hi Arthur

Here's my 2c.  Go to the Crucial website www.crucial.com - from the system in question.  Use the Crucial System Scanner Tool to "Scan My Computer".  Allow and run the download.

*Nearly* always, it will identify your motherboard accurately, together with what RAM is installed and what empty slots you have.  You probably already know all this so far, *but* crucially(!) it tells you what kinds of RAM are compatible, whether ECC or not, CLs, PCxy00s, DDRz00s, etc etc, and *guarantees* compatibility.

Of course you don't have to buy from Crucial.

Subject: [dba-Tech] RAM Terminology


I'm shopping on eBay for some additional RAM for a computer that allows only DDR1 (I can't afford a new motherboard as well). There's plenty to choose from there and the prices are better than the local stores charge, but before I take the leap, I'd like to clear up some terminology that I don't
understand:

- low-desity RAM (a few listings say this)
- high-density RAM (only one mentions this)
- (M368L2923DUN-C​CC) for De<http://www.ebay.ca/itm/Samsung-1GB-DDR-PC3200-400MHz-M368L2923DUN-CCC-Desktop-RAM-/120783314737?pt=LH_DefaultDomain_2&hash=item1c1f3f1f31>sktop
RAM (only one mentions this)
- Non ECC (only a few mention this)
- CL3 (a few mention this)

I don't need a detailed thesis, just some guidelines. Is high-density better than low, or vice-versa? If neither is mentioned, does that imply the rest are "medium" density? The RAM I already have is 400Mz and nobody seems to offer higher, so I'll stick with that.

TIA,
Arthur
