pretty low vdimm there dude

let's see some 2.4vdimm benchmarks

how the hell'd you find MT16HTF12864AY-800D4 :confused: don't see it listed anywhere :D

These are single-sided sticks, right?

Great results with low Vdimm and DS3
Hopefully more voltage action with P5B soon
Thanks for sharing

D9HCD is lower bin D9GKX.

D9HCD is rated 800MHz CL6-6-6, while D9GKX is rated 800MHz CL5-5-5.

Still quite nice IC´s there.

Same manufacturing process and revision ?

Yes.
No difference what so ever except the binning.

What is the relation of these 2 IC's to GMH, I'm curious and new to just about everything extreme. (I only overclocked starting 6 months ago :))

My guess is that they are as good or a little bit better than GMH.

GMH = 333mhz, 5-5-5
HCD = 400mhz, 6-6-6
GKX = 400mhz, 5-5-5

stock specs from micron. all 64x8 ICs :D

btw, ever gonna edit your sig? ;)

Nice overclock, try to give 2.6V for those sticks.

Where can I get Micron sticks in Toronto?

Found Micron Manufacturer's Representatives in
Tech-Trek Ltd.
1015 Matheson Blvd., Unit 6,
Mississauga ON L4W 3A4
CANADA

Anyone tried to get them in Tech-Trek?

No, they are doublesided.

The ICs are 512Mbit 64Mx8. Each IC is 64MB (512Mbit ÷ 8), so you need 16 ICs to make 1GB per module.
16 × 8 = 128 datalines, so it's doublesided (64 datalines is singlesided).

Anyway, nice find! I added the info to my RAM List and Micron DDR2 IC Info page.

Yeah, give it a little more juice. Also, good find how much did you pay for it?

Okay, I guess I was thinking of the 78nm shrink, D9HNL which were single sided, and I just assumed these were in the same family (D9Hxx).

That's because D9HNL is a 1Gbit chip. You would need 8 of them to create a 1GB module, which gives a total of 64 datalines (singlesided).
If D9HNL would be used to create a 2GB module it would have 128 datalines making it doublesided. :)

Also, D9HCD is not part of the same family as D9HNL:

D9HCD = B6-25
D9HNL = HQ-3

So these will be used in Micron new 2 GB sticks?

I buy it from online auction in Taiwan,cost $7000NTD ($210USD)

vdimm=2.35v (+0.7V in BIOS)

http://219.84.132.86/ftproot/060404/.../d9hcd_850.png

But 965P-DS3 V1.0 is not good for 1GB*2 overclocking,can't boot at DDR2-1066 4-4-4-12 ....:(

Thx tests.. I think equal or better than D9GMH.

D9HNL (1Gbit) will be used in 2GB sticks, not D9HCD (512Mbit).

Originate frm singapore??...
my country.... hmm...
hmm.. let me go check with my local distees...
the voltage is great...

Whats so good about this RAM??
You've lost me on this one,they're a pile of crap.

They're really not bad though, all the tests in the first post are run with 1.87Vdimm on a DS3. DS3s are terrible at clocking RAM compared with most P965 boards. The most recent BIOS updates have corrected this a little, but a P5b-E or P5B Deluxe would still do better.

this RAM is very good...he needs a 680i or P5B Deluxe to test for true clocks but this is looking great
