Micron D9GKX's sister--D9HCD results

[oijkue]

Got 1GB*2 set of Micron DDR2-800 today




DDR2-800 CL6




D9HCD chips




According to This
D9HCD--MT47H64M8B6-25 D (DDR2-800 CL=6)
D9GKX--MT47H64M8B6-25E D (DDR2-800 CL=5)

Compared with D9GKX




System:
CPU:Core2 Duo E4300 (ES)
MB:GIGA 965P-DS3 V1.0 (BIOS=F10)
MEM:1GB*2 D9HCD chips
VGA:ATI RAGE XL PCI
VDIMM=1.87V


3-3-3-9 DDR2-700



4-4-4-12 DDR2-920



5-5-5-15 DDR2-1050

pretty low vdimm there dude

let's see some 2.4vdimm benchmarks

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

[Omastar]

These are single-sided sticks, right?

[kemo]

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


btw, ever gonna edit your sig?

[noroger]

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?

These are single-sided sticks, right?

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?

[Kabauterman]

I havn't see HCD on other Sticks before.

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).

[Rone]

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

[Phosphate]

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

[oijkue]

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

vdimm=2.35v (+0.7V in BIOS)



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.

[Hazzan]

Nice chipset with low voltase

[Rone]

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

[clon22]

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

[dinos22]

hey clon22 long time no see

let us know how you go with your disties heh

[berk]

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.
