Micron D9 is seen as the BH-5 of DDR2, "tight" timings even while OCed pretty high

Everything else is like Infineon, Mosel, and low end Samsung in DDR, okay timings at low OCs.

Those are the ones that I had that I couldn't get over 900mhz, I was pizzed and sold them on eBay for $300 and bought my G.Skill for $290 and now my G.Skill are doing 1000mhz easy. So my guess is that I probably didn't get the ones with Micron D9s but the PROMO.

But then again, some other guy here, can't remember his name, got his to over 1000mhz, except I never saw a cpu-z or ss to see if it was true though, so to this date I'm skeptical about them if they have indeed Micron D9s ICs.


What he said but also the bandwidth, they can scale to over 1100mhz with a mere 2.3v whereas other type of ICs may not even brake the 1000mhz barrier with a 2.45v.

Why do they even make the other not-so-good stuff then? Isnt it easier to make all D9 and charge more?

The difference is, the micron D9's are awesome ocer's, they respond very well to volts. OC's like my D9's easily hitting ddr21000 speeds with tight timings are the norm, not the exception. Time after time they've proven themselves as superior to almost all other (or all actually?) DDR2 IC's, only occasionally should there be a "bad" set that doesn't oc well, as I said you would get that with ANY brand IC's. They are worth every penny....

I've had a few of the "other" stuff, and so far it's never as good. This is widespread too, this isn't just me getting these results, it's most other people too usually. For Corsair's in ddr2 anyway, I've OC'ed 2 sets of Infineons, and now some Promos as well. I guess what I'm getting with these Promos is about the norm for them.

Kind of, each vendor will use their own numbering system I'm sure. Just because for Corsair 6400 C4 v1.x means you got micron, that doesn't necessarily mean squat if you're talking OCZ or Gskill or whatever. But generally, the micron will be found only in higher end ram like:

Corsair 6400 C4 XMS2 "high performance"...ehhh ehm *cough* I guess maybe not anymore.

or Gskill HZ's---I think this is still true anyway. I don't know if all version HZ's are D9's, maybe nasgul knows.

I doubt you'll find a set of value ram with the micron D9's on them, unless in a year or two they bin and sell the odd sets that didn't monster oc. They'll market it as low cost performance ram lol. With how good these IC's are though, I don't know if they'd ever get enough mediocre sets to make a new ram line heheh.

Cool thx for clearing that up.

RoscoeMcGurk

I think right now we're at the point where you could still potentially get either, but more likely the promos since they seem to be switching to it. They started with the promos on these sticks not too awefull long ago. So whether you get micron may depend on how long that set's been sitting on the shelf. Every day that passes will probably decrease the chances you'll get micron.

Hopefully they'll soon start using the D9's on the C4's again soon. Already though since they switched it, I'd have a hard time recommending this ram to a serious OC'er. I don't like the crapshoot aspect of it all. Make sure they're v1.x before you get them people, call them before you order and make them look on the sticker, and tell you if it is lol, if you really want D9 anyway. Sorry if anyone feels I'm bashing Corsair, I feel as if everything I've said is just being honest, and IMO these IC's should only be on far less expensive sticks! Sorry Corsair, just trying to help the enthusiasts, your profit margin is good enough I think. You should know that feeding us veal for a premium price, then switching to chuck steak but charging the same, will leave some people with bad tastes in their mouth. You know how well, or lack of actually these OC, and you know plenty of enthusiasts (that's who they're geared for, for pete's sake) are receiving these and being very disappointed.

I have the 6400C4 PRO (one with the plat. heat spreader and LED's), i'm not sure if they use the same modules as the 6400C4 or not, but mine do over 1000+ if I put some more vdimm to them. Currently using at 4,4,4,4,11@1056Mhz with 2.39 vdimm. I also got these a few months ago, before all the crazy price hikes so I assume I have the D9 modules.
