Corsair TwinX1024-3200XLPro

Interesting article.

You've picked up on a finer point here, that even the PCB design can play a small role in performance.

There are literally dozens upon dozens of different PCB boards for DDR-400. It's rare for an article to go into detail about the PCB.

I've noticed two general specifications in PCB design.

One is the PCB board layers. The industry standard for DDR-266 and DDR-333 is 4 layer boards. For DDR-400 both 4-layer and 6-layer PCB boards are widely used. 6-layer boards of course are better as they provide more room for grounding wires.

All original major DDR-400 modules use 6-layer boards, whereas most value ram or OEM brand use 4-layer PCBs, because it's cheaper. This is only one reason why I always recommend major original brands; they have better compatibility. ...something to think about.

Secondly, many PCB designs have different profiles and network layouts. Some PCB boards use an embedded-resistor network, while others use non-embedded component networks. You can bet that some companies are very picky about the PCB layout design; you'd win that bet.

I cannot comment further on the PCB design in terms of performance.

Most consider Brainpower to be #1 in PCB design.

Most manufacturers can get TCCD chips and build then to custom PCB boards. Which may not be a good thing.

It's best to buy original modules from reputable sources.

Corsair's Twin XL series is pretty damn good. Are they using Brainpower PCB?

Nothing new there, I've been saying the same stuff about Corsair XMS and Crucial Ballistix for how long? My Corsair XMS PC4000 Pro won't run lower timings at PC3200 speed, but my Crucial Ballistix PC4000 will run 2-2-2-5 at PC3200, 2-2-2-8 at PC3500, 2-3-2-8 at PC3700, and 2.5-3-3-8 at PC4000 speeds. That means it compares to the best Samsung RAM.

Ah, but you've done more TESTING than me.
