Whats the signal integrity like on current DDR modules? (Or any RAM for that matter)

I know the principles behind data problems (did some for Principles of Computing) but is it a significant amount on existing modules?

There's that unwritten bit of marketing in anything like this, but DDR2 speed increases have slowed considerably since the initial launch - a bit like the way that DDR got to 550MHz quite quickly, but then didn't go much further. With that said though, I don't think that any of the memory manufacturers would disclose signal integrity details outright, but if two have said that they need to improve cooling to increase speeds, I'd say that the problem is starting to become a problem.

Implementation at 1100-1150MHz suggests that the problems will start to become apparent above 1200MHz.

isn't this a little overkill? how much heat can these things make?

DougEdey · 21st Nov 2006, 12:01

That would make a lot more sense, since the current drawn by a stick of RAM can't be a lot. so the only way for signal loss to become apparent would be by inducing current by high frequency.

Micron lists their current draw as 3mA to 4mA

You'd be surprised, my Crucial Ballisitx are only slightly over-clocked and after an hour or so of gaming they are so hot you can't hold them for long.

Anyone else notice that the "perfectly aligned fin design" won't exactly work all that perfect unless you have your motherboard lying flat - which won't happen in most cases (pun). And boy are they ugly!

This seems to be gettin pretty nuts for water cooling. Quite a few people (the people who would buy this ram) will have 2 loops, one for gfx and one for CPU right? So now they would need a 3rd (for maximum effectiveness) to cool their ram?

This is getting obscene (and obscenely expensive) don't you agree?

Also, what kinda rig would require ram at this speed?

Kipman725 · 21st Nov 2006, 17:16

yelids of ram chips that can run that fast are very poor so I wouldn't expect to see any much faster than this untill DDR3 or whatever is next.

Marquee · 21st Nov 2006, 17:43

I have been waiting for RAM that has a sleek and smaller RAM block for water cooling.

nice, I like this as an option for sure instead of having to buy like Ramplex for liquid cooling and its a nice combo with the heat fins. Hope to see more of this design or if anything hope that OCZ will offer a stand alone of this hybrid cooler to attach to existing memory ^^
