Okay, i see that comment too much, so i'm going to nitpick on you today, sorry.
While it's semi true sorta, it's not the whole picture, nor entirely accurate.
With most DDR2 Micron, the factory stock speeds @ 1.8v JEDEC approved are known.
D9GMH is DDR2-667 5-5-5 1.8v by default.
D9GKX is DDR2-800 5-5-5 1.8v by default.
D9JKH is DDR2-1066 7-7-7 1.8v by default.
And so on.
But for PSC or really any of the other manufacturers of RAM, i've never found the default ratings published or listed anywhere, which means that saying that G.Skill is DDR2-800 overclocked is an assumption.
For all we know, it might be DDR2-1066 6-6-6 1.8v at default...the fact is, there's no proof what speed it was manufactured for.
So you can't really say it was DDR2-800 overclocked, since there's a lot more to it.
And binning by the companies selling it (G.Skill, OCZ, etc.) also determines how good a kit may do.
Generally, especially as a certain IC ages, they tend to have more & more kit outs out, & they tend to get better & better with binning, which is why i've said before i actually like when companies don't sell so many different rated kits.
The fewer they have, especially if they have no "high end " DDR2-1066+ kits, the better chance you have for a higher OC from the lower end cheaper kits.
Now that's a bit of an assumption on my part i will admit, but it's generally backed up with people's OCing results.
Once they have so many different kits like G.Skill does right now, the odds of getting great clockers from their cheaper stuff becomes smaller & smaller.
But on topic, don't say it's factory OCed DDR2-800...
There are a number of ICs out that are DDR2-1066 7-7-7 1.8v default now, & sometimes those are what gets turned into the DDR2-1066 5-5-5 2.0v kits in some cases.
P.S. The values in CPU-Z's SPD tab are just that. SPD values programmed by the manufacturer (G.Skill, OCZ, etc.).
They are generally NOT the default speed that PSC or Elpida or Samsung or Micron designed them for.
You can get a SPD modifying tool & change those numbers yourself...Edited by -n7- - 7/30/08 at 7:41pm
