reset-nvram, reset-all necessary with RAM upgrade/EFI?

When you upgraded or downgraded ram with the ppc architecture it was always best practice to reset-nvram, reset-all within open firmware. I've gone through apple's documentation and done a little research on the internets and can't find out if this is still necessary.

Since intel macs are using EFI instead of Openfirmware, is this no longer necessary?

macbook 1.83ghz/512/60gb/combo (2gb transcend arriving this week), Mac OS X (10.4.6)

You will not need to reset nvram or do any other modifications once the new RAM is installed. Simply turn it on, boot into OS X and make sure it's all showing up correctly in "About this Mac". That's about it!

Thanks for the reply. Just installed 2gb (2x 1gb transcend sticks)

So far so good:
1.83ghz, wifi, bt, dashboard widgets off, no apps running
Xbench @ 512mb = 48.31 on batt, 'normal'
Xbench @ 512mb = 45.18 on AC, 'best performance'

Xbench @ 512mb = 60.29 on batt, 'normal'
Xbench @ 2gb = 59.09 on AC, 'best performance'

Apple System Profiler reports that both transcend sticks are running @667mhz, which was a problem with patriot mem.
The 2x256mb sticks I pulled out were hynix mem: HYMP532S64BP6-Y5 AB, I was surprised. I thought apple used samsung for these macbooks.
