Also, I remember way back when I did hardware support that we always had balanced RAM, meaning if there were multiple sticks they were all the same. Is that still true and I should pull the 2GB when I install the 8GB, or can I put both of them in? -- Drew

If there are more than two slots, the two channels are laid out (A and B) thusly: BABA. They need to be matched pairs. Single channel will work, but there's definitely a performance advantage to dual channel.

You'll see a big improvement with the 8GB stick added. Some of the recent "business" laptops from Dell have only had a single memory socket. Lack of dual-channel is not a huge deal in most cases. Cheers, Scott.

Anyone got some old laptop RAM lying around? - (drook) - (18) - Dec. 17, 2020, 10:47:27 AM EST

I probably do. - (Another Scott) - (14) - Dec. 17, 2020, 02:34:09 PM EST

Yes, SO-DIMM ... I assume the pin count is the same - (drook) - (13) - Dec. 17, 2020, 02:40:48 PM EST

I've got a lot of older DDR2 stuff, one stick of DDR3 - (Another Scott) - (12) - Dec. 20, 2020, 04:49:21 PM EST

32 bit Windows can't address over 4G - (drook) - (2) - Dec. 20, 2020, 05:04:44 PM EST

Ah, that's right. Good plan. -NT - (Another Scott) - (1) - Dec. 20, 2020, 05:54:54 PM EST

Hmm ... Upgrade time - (drook) - Dec. 20, 2020, 09:52:38 PM EST

Got 64-bit Windows installed, just ordered the RAM - (drook) - (8) - Dec. 23, 2020, 01:36:05 PM EST

I've got a few sticks... - (pwhysall) - (2) - Dec. 21, 2020, 01:36:38 AM EST

They seem to still be producing it for laptops - (drook) - (1) - Dec. 21, 2020, 07:17:07 AM EST

DDR3 is still vee cheep. - (pwhysall) - Dec. 21, 2020, 10:42:53 AM EST
