Micron D9 question

[nipplefish]

Here's the situation: I have a pair of 1gb Team Xtreem DDR2-667 sticks using Micron D9 chips. I've just installed Vista so I'd like to move up to 4gb. Problem is, I can't find these sticks anywhere for a reasonable price. Tankguys.com has them cheap but the site shows them on backorder and I think the site is dead because they haven't updated since May.
Does anyone know if using a different brand with the same chips will match up well enough for overclocking? And if so what is available right now that uses these chips?
Thanks!

There are still a number of 2x1 GB kits using D9GMH, but that number is shrinking rapidly, as those ICs are all EOL.

I couldn't tell you exactly which kits will use those ICs; i honestly stopped followed the 2x1 GB scene long ago.

I'd personally recommend picking up a 2x2 GB kit.

That will use PSC then, which doesn't need much for voltage, & should clock well, without the added hassle of running 4 DIMMs.

Or you could do what my buddy & lots of others are doing, run 2x1 GB + 2x2 GB (assuming Vista x64), though you might need to set things up a little more carefully in the bios.

FWIW, i don't find mismatched pairs is impossible to run or bad per say at all.
You just need to ensure you find settings that are a good balance between the two different types.

I guess I'll look into picking up a 2x2 kit then. I'd always operated under the assumption that mixing memory types was a big no-no, at least for overclocking. Do newer boards support it better, or is it something that has always been overblown?

Overblown.
And lack of knowledge

I ran mistached 8 GB, yes, 8 GB, on my old P5B-D sucessfully overclocked no less with mismatched G.Skill & Mushkin.

Obviously, matching is ideal, but if you don't get too unlucky & are okay with changing voltages, & timings in the bios you will usually be fine.
Sometimes consulting the documentation on which slots to use is also needed, as most motherboards have specific ways to put in single sided vs. double sided, larger capacity DIMMs. vs. smaller, etc.

At werk, i upgrade customers' systems with mismatched RAM all the time, & it's extremely rare i ever find any issues.
