Dual channel really worth it?

[Sniper82]

Is it really worth it on a AMD. Is it real noticeable?

What AMD Platform ? and doing what ? Not really, except in some cases on the Athlon64/Opteron platform (forget exactly what it was, but memory bandwidth DOES actually double on my dually Opteron over my Athlon64) I will check the benches, and reply if I find it.

i noticed little difference between 1 and 2 sticks, although going from 333 to 220 fsb seemed like at least 10% improvement, and was good for a 16500 to 17000 jump in 3d mark 2001 with a slight clock decrease.

dual channel makes virtually no difference.

Does dual-channel function the same way as a RAID 0 setup on drives?

Just a XP/Nforce 2 1800+@2.2Ghz 200FSB. Just little gaming,surfing,email,ect basic stuff

On an AthlonXP, it makes virtually no difference. The CPU can't use more than a single channel anyhow.

Dual channel will add about 5%-15% performance to Athlon 64 systems.

Show me one bench adding 15%. 2-5max is more like it.

Start on page 13. OP you look here too.... keeping your eye on 754 3400+ vs 939 FX-51 to see the miniscule dual channel difference.

No real difference on an AMD system.

Only if you're using the nF2 IGP.

- M4H

Yep, 2nd that. It's a big difference when you use in IGP.

Otherwise dual channel matters for Intel and not AMD.

You all can't say only when you are using the integrated graphics that dual channel ddr is worth it. Look at the results in the link below. There are consistent increases in performance with dual channel ddr over single channel ddr. Especially if you do Workstation type work.
