Can you answer my 2 month old LOD question now

Thank you very much.....

....and the question was?......

[Kunaak]

this was my only D9.

unfortunatly, in my curiousity, I killed the ram removing the heatspreader
one ram chip fell off, so I knew it was dead and just ripped the rest off.

I figured... well it's not that expensive, I will just buy another one.
after an hour online, I see its not made anymore.
it was made around late 2004 early 2005.
then replaced with 5300...

pity, cause this stuff was cheap when it was at newegg.

anyways, heres some photos of me destroying some D9.

by the way, I had this stuff up to 700 mhz at cas 3-2-2-4 on a crappy ass Abit 925X board... not even the XE, but the old junky X board.
I been saving it for a good DDR2 board...
but today I got curious, and killed it on accident

Sorry to revive this thread but I am starting to hunt for some D9 Fat Bodies and will be going o some local store in hopes of seeing some. does the XXX in D9XXX signify wether it is a stepping or which type of D9. Is the way to tell its fat body buy the rectangular shape versus the square?

Thank You
Tim

Micron D9DQT & D9DQW are the rectagular chips that you're probably looking for. I'm pretty sure they are no longer produced. Most of the newer D9's are square-shaped and not so-called Fat Body chips.

As someone else pointed out, D9 is just Micron's code for DDR2. It has no special meaning other than that. Some people think D9 and Fat Body are the same thing. They're not. D9 just means Micron DDR2. It's what you'll see etched onto the chips. On Micron's website, they don't list the chips by D9XXX. Instead they use the part number. You may see something like "MT47H128M8BT-37E". The code after the hyphen indicates the cycle time, cas latency and rated speed. For example, "37E" in Micron-speak means 3.7ns, CL4, DDR2-533MHz.

Thank you very much sierra_bound. I know my luck will be hard pressed to find some fat bodies but maybe fry's or somewhere will have a old rev of the ddr2 8000 which would make me ever so happy.

Thank you
Tim

I don't think that you can find fatbodys on cheap pc8000 sticks .
Better look on pc5300 & pc4200 . Old sticks from crucial/micron have the most chances to use fatbody .

[Cpt Twitchy]

I will keep my eye open to those when I am out, thanks.

[sierra_bound]

Don't overlook some of the newer chips like D9GMH which perform very well at a better price point than the old Fat Body modules. The one thing about the older Fat Body chips. They were mainly found in 512MB modules. Not sure if that's an issue with you.

BTW, I was looking at the list of modules in the first post. I believe some of them are not Fat Body sticks. For example, Corsair 6400 probably uses Elpida, though I'm not 100% certain.

[Cpt Twitchy]

I am sure some of the sticks in the first post are still around with different ic's being used. What kind of speeds can D9GMH hit and with what kind of latency's? I like to bench pi and the if there is something else out their that can match the low latency's I will go after them as long as the prce is nto rediculous.

[sierra_bound]

The older Fat Body chips can run 3-2-2 or 4-2-2 at pretty decent speeds. That was one of their big selling points. The newer D9's like D9GMH probably run best at 4-4-4 or 4-4-3. You can get them to do 3-3-3 too. OPB has a thread on the TeamGroup 6400's which use D9GMH chips.

This is just my opinion but I think people overrate the importance of cas latency on DDR2. Certainly you want to avoid CL5. But you're not going to see a huge difference between, say, 4-3-3 and 3-3-3 at the same memory speed.

[sierra_bound]

Here's an example of what I'm talking about. This was not done with Fat Body modules. But compare 3-4-3 with 4-4-3 at same CPU speed, same FSB and same memory speed. Different modules used (Corsair & Super Talent).

[Cpt Twitchy]

Thank you for doing that little test. Now I wonder if the tighter timings Fat Body can pull on ras to cas and ras precharge make much of a difference.

[sierra_bound]

RAS# to CAS# Delay (tRTC in Intel memory tweaker-speak) is more important IMO than cas latency. BTW, I'm not discounting CL altogether. The one advantage to running CL4 versus CL3 is that you can generally get higher memory speed.

With 2X1GB kits, the tightest timings you're going to be able to run are probably 3-3-3. If you want to run tighter than that, look for an old 2X512 Fat Body set.

[Cpt Twitchy]

Thank you a ton sierra_bound You really helped me out.

Has anyone confirmed that the Patriot 6400 is or isn't fatbody? Model # PDC21G6400LLK

there is a ton of patriot on ebay...

I asked fugger about the Patriots and he said that they changed the chips. He said that all of the black heatsinked sticks used D9 fatties, and some of the red ones. They don't make the black ones anymore, so you know that if you see some with black heatspreaders, they're D9 fatty.

Or maybe I'm getting mixed around and all of the red ones used D9 fatties...

[TheMeatFrog]

I have a chance to pick some up with black spreaders. Maybe I should PM him and ask.

Edit: Straight from the man himself...

80% chance they are Elpida.

Red heat spreaders are 100% the best D9

[Supertim0r]

red or black = fat D9 ?

[5-Clicks]

both. red = guaranteed D9 fatty.

[TheMeatFrog]

The ones I was looking at had black spreaders so I opted to pass on them. My search for the fattys continues.

[5-Clicks]

I think your best bet at the moment will probably just be to get some Crucial Ballistix off of ebay and hope for the best...

So you're saying mine are Fatbody?
Why don't they oc that great then?
646MHz 3-3-3-4 @ 2.25v
830MHz 4-3-3-4 @ 2.25v
896MHz 4-4-3-4 @ 2.25v
960MHz 5-5-5-15 @ 2.25v

Maybe I should take of the heatsinks, but will I be able to reattach them?

Probably the reds use Fatbody D9, and the black ones some other Micron IC's.
I've contacted Patriot and they say they only use Micron for theire DDR2, so no Elpida.

[[XC]Atomicpineapple]

SMA, from what I've read fatties need voltage!!!!!

[SMa]

Are there some other characterizes of Fatbody D9?
e.g. do they get hot?

If I remove the ramsinks, you guys think I would be able to reattach them?

I can't test with higher voltage because my board is limited at 2.25v
