[GTALUG] war story #2: buying RAM

| would certainly work.  It is listed as compatible, it is 3200 DDR4,
| it is 1.2V.  No silly XMP profiles involved.  So such memory does exist,
| but it is not very common.  Most ram just ups the voltage using XMP
| profiles to get the higher speeds.  You need really good chips to run
| 3200 at 1.2V.

Thanks.  I wandered around from there.

Next stop ca.pcpartpicker.com

I cranked various parameters.  The key ones:
- speed: at least 2300
- voltage, min and max: 1.2

I got to
<https://ca.pcpartpicker.com/products/memory/#ff=ddr4&b=ddr4&S=3200,8000&Z=8192001&E=0&sort=price&B=1200000000>
I ignored the entries without prices -- I assumed that they would be
hard to finde.

The latencies were all the same.

I chose
<https://ca.pcpartpicker.com/product/Pkyqqs/crucial-64-gb-2-x-32-gb-ddr4-3200-memory-ct2k32g4dfd832a>
That was the second cheapest but it was the cheapest from a vendor I
have experience with -- in this case Amazon.ca.
Amazon.ca would sell me one that had been returned for $10 less but
I would always wonder why it had been returned.

PCPartPicker.com might well have missed some options but I am really
weary of the hunt.
