So D9GKX is better than D9GMH?

[fhpchris]

I wouldnt know my mobo max's @ 460ish with my D9's
4-4-3 though 2.1V

run 4-4-4 @ 2.4v

[Yay for Cheese]

If D9GKX is better than D9GMH, then how come not very many people have the OCZ DDR2-900 Platinum EPP?

[Revv23]

If D9GKX is better than D9GMH, then how come not very many people have the OCZ DDR2-900 Platinum EPP?

because thats a new ram with hardly any marketing?

Anyways GKX is typically better then GMH, but not always, giel has tons of D9 GCT(lower binned then even GMH) that does better then GKX.

Remember, they are all the same modules, so just because micron binns them as GMH or GKX doesnt mean that corsiar or ocz or gskill cant bin them on their own.

That is how team sells GMH that is faster then GKX, they bin them like crazy.

edit - Thanks very much to jmax for the part number of D9GCT!!

Thank you sir!!!

It is this simple on average (this is spec from micron):

D9GCT is 533
D9GMH is 667
D9GKX is 800

of course you can sort the ics and get better results (not average as i posted above).

Any idea what chip is used in CELL SHOCK PC6400 4-4-4-12?

[jmax_oc]

I saw somewhere the price for D9GCT, GMH and GKX chip...
Can anyone help me finding this post ?

[Cordovader]

Any idea what chip is used in CELL SHOCK PC6400 4-4-4-12?

From what i read D9GMH for 6400, D9GMH or D9GKX for 8000 C5 and D9GKX for 8000 C4.

[Ibinco]

gracias por el info Cordovader

You can't go act like a noob and ask "D9GMH vs. D9GKX, which is better?".
The D9GKX are not "better" then D9GMH, although from what I've seen it can operate at higher frequency when it goes to voltage ratio.
But when you look at maximum frequency, you can clearly see one is not better then the other, and if you look closer you will notice that some D9GMH can way outperform any D9GKX.
Basically, both are great.

With active cooling (80mm fan blowing directly on the sticks) is o.k. to put 2.6v for 24/7 use on either bins?

[Marvin_The_Martian]

I orderd some OCZ2TA1000VX22GK two dayes ago at a dutch online retailer, didn't get a confirmation email so I called them twice today as they went out off stock 20 minutes after I placed the order and posted it here... yet no one repleid

Anyway, twice they told me that yes they had it in stock and I seemed to have gotten their only pair. It was internally packaged and probably already shipped out to the postal service but I haven't gotten a confirmation email because they didn't get the shipping number yet.

I got a funny feeling though... Hehe well it will be the most expensive single part I bought upto now and hopefully from now on

Hoping my D9GMH will be exceptional lol, for the rest I concur with Mr. Popo uptil now no signs off one being consistently better then the other afaik

maybe...

2.4 is high, 2.6 is really high, i run mine at 2.7v... will they live long and prosper?

Well, my fingers are crossed. .


For the record G.S. Tech reccomends no higher then 2.4 for 24/7 IIRC

[The Stilt]

Micron seem to have quite lazy employees working in their "binning department"

These modules are based on MT47H64M8B6-37E (3.7ns, D9GCT) ic´s and Brain Power B62URCE 1.0 PCB.

With 2.2V they can do 6hr+ HCI Memtest at 400MHz and 3-3-3-4 settings.

With higher voltage (2.65V) they can easily pass SuperPI 8M calculation at 470MHz with 3-3-3-4 settings. Additional cooling is required of course.

Hand picked pair?
Certainly, but the difference between the best and the worst pair was hardly worth of mentioning.

Nice set there stilt..

I wish I had a decent mobo to allow this Kit of team 667 GMH to got their freak on..

This dam DS3 is also holding my 6300 back as well

One day ill get a p5b Deluxe in hands and see what these babies can really do..

[metro.cl]

i got some inside info:

D9GCT is 533 cheapest one can also take high volts
D9GMH is 667 best for high volts and tight latencies
D9GKX is 800 bad for high volts and tight latencies (best for low volts)

[[cTx]Philosophy]

^^^HMMM verrrry interesting^^^
Ive been trying to figure this out forever, thanks for putting this into perspective..

[Mr. Popo]

i got some inside info:

D9GMH is 667 best for high volts and tight latencies
D9GKX is 800 bad for high volts and tight latencies (best for low volts)

This "inside info", is already well known.
D9GKX are pretty good under low V's.
But, D9GMH loves the "extra" V's.

MT47H64M8B6-5E (D9GCW, CL3)
MT47H64M8B6-37E (D9GCT, CL4)
MT47H64M8B6-3 (D9GMH, CL5)
MT47H64M8B6-25E (D9GKX, CL5)

As far as I know all of the IC´s listed above are based on the very same Revision D design, which in this case is packed in B6 casing (60-pin FBGA 10x10).

There shouldn´t be any technical difference between these IC´s, they are just rated to different frequencies and IDD parameters (latencies).

The difference should be as similar as the difference between Winbond BH-5 & BH-6

i knew the same thing before, but talking to someone at RD from a well known ram manufacturer he told me this, my guess is that they are binned in a diferent way, so the whole this is better couse is rate for 800mhz isnt true when overclocking, i've been told that ghm can do 1200mhz 2.4v if cherry picked on 965 platform (cas 4)

Sry noob question, how come 3ns chip oc better than 2.5ns chip?

[Mr. Popo]

Sry noob question, how come 3ns chip oc better than 2.5ns chip?

You need to understand everything on your PC is consuming power.
So, when you use less V's for one thing, you can use more for the other.

[GrimReaper]

so whats the list of ram that currently come with GKX

[bengkiam]

Ok, so the simple explaination is a 3.0v D9GMH will outperform a 3.0v D9GKX with maximizer, right?
