Ram-pocalypse

Hi ClaudioM,

I heard this in the Future feed, and had to listen again.

Impressive that you were able to find RAM with the
current Ram-pocalypse

Looking forward to the follow-up episodes of your
tech hoarding adventures.

Cheers,
Archer72

Re: Ram-pocalypse

Thanks, archer72! Yeah, when I bought the DDR3 module, it was a little more expensive than it used to be, but nothing like DDR4 and especially not like DDR5. The module I moved from the Evoo to the T495 was DDR4, but I bought it early on, just when RAMpocalypse was starting. Still a little pricier, but not as bad as now.

Re: Ram-pocalypse

Hi,

I was lucky enough (or had a hunch) about getting enough DDR4 to max out my HP600 mini PC with 32 Gb and the Acer Aspire 5 with 16 Gb DDR4. The Acer is still not a fast computer, but works for what I need.

P.S. Shhh.... Don't tell RAM Altman.

Cheers,
Archer72
