I orded some Crucial PC3200 512 dimms from Newegg and what came in is not TSOP but TBGA. The 512 dimms are single sided and looks like 1 gig dimm with TBGA are out there as dubble sided dimms.
This is DDR and not DDR2.
The part number on the chips are
5KDII
D9FBN

EDIT did some test ing and it did memtest stable at 220HTT 2.5,2,2,11,T1 2.6V

Oh, the results look great! The only questions that I'd still have are the following:

How far will they get, overclockwise?
Will they scale with higher Vdimm?

That for some one else to find out. I can only use 2.6V or 3.3V. My mobo is set to 2.6V with no other setting. I have a turn on turn off Vmod that feeds the diims slots direct for the PSUs 3.3V rail. Im not feeding it 3.3V knowing its new so im stuck at 2.6V.

i don't think those will benefit from higher voltage.

bga ic's are made using smaller manufacturing process.

The smaller manufacturing process doesn't necessarily mean that they won't scale with higher voltage. ;)

Well if they are single sided then you can run 4x512 @ 1t then which is a nice benefit in speed. Not to bad on the oc either. Cant you reduce you 3.3v rail on psu to 2.9 so it only feeds the ram that ?

usually it does. not that they won't scale, but higher voltage could be harmful for them.

for example, tccd is smaller manufacturing process than any winbond ic's. i don't know the exact numbers.

also, ch is manufcatured using smaller process than bh. and as you can see there are more ch deaths than bh.

Yes, I absolutely agree with you. But when I said higher voltage, I didn't mean 3.5V. Anything above 2.6V would be interesting. And I don't think that 3V with a fan blowing on the sticks, would do any harm.
Anyway, I think I'll see if I can get some sticks of that RAM and then I could test it out on my own, if noone else gets them before me. :)

yes, of course, upto 2.9v would be nice to see.

its just that when you mention 'higher voltage' i'm thinking 3+v.

as for testing, give it a shot if you can, i'm curious also. :up:

This dimm is for a for a system for some one else so that is all I doing with it. If it was for me then I would use the 3.3V with this colling on it.
