DDR3 questions

80251 · May 12, 2021

1. was 1866Mhz. the fastest DDR3 memory ever manufactured?

2. what was the upper bound on the frequency DDR3 could be overclocked to on say sandybridge (and sandybridge-e) or broadwell (and broadwell-e)?

1. If I recall, 2800 MHz was top end.

2. I think it more depended on the motherboard, but this was long ago.

sandy bridge capped at 1866
Ivy bridge did 2400 for me personally, i have no idea what max someone else reached

I’m still pushing 1900 but it’s chip limited

If it helps my 3770K caps at about ~1100-1150MHz even with 1200MHz ram

I've got 3100mhz DDR3, but nothing that can exactly run it.

With sandy bridge i wouldn't go higher than 1866mh

it cant - there was a hard BIOS lock. I had a 2500k that i moved to a 3770k, so i could use my 2400MHz ram.

Thanks I got ivy bridge mixed up with broadwell. 2400Mhz. is still pretty good. Did it do 2400Mhz. with better latencies than that seen on later DDR4 architectures?

You can get CL10 2400MHz rated kits or 2133MHz CL9 (1,65V), and they should OC on top of that. If your CPU is able to do it... up to you to check. My Ivy-E does 2133MHz CL9 fine with 32GB of RAM.
It REALLY doesn't like 2400MHz speed though (lower write bandwidth than 2133MHz setting).
