I guess it is. What are the average max frequencies of them, repectively? Say, at 2.4~2.5V. If anyone knows sticks that utilize D9GKX could you share the information? I checked out the stickies but they don't seem to be terribly up-to-date.
Thanks!

My G.Skill 1000 HZ has D9GKX on it - no warranty that all of them have the GKX... but i assume it...
Are there difference performance characteristics between them that you can tell by testing? (Clock frequencies would be one obviously)
Edit: In other words, is D9GKX exactly same chip that was binned from D9GMH, or is it from a different rev., tweaked process, etc.?
I modded my P5W yesterday (before only 2,4V Vdimm)...
I havent got the final results... But with 2,9V 450 MHZ 3-3-3-5 seems okay; 1140 at cl5, too.
I'll have to do more testing before i'll be able to say something for 100%.
I dont have any D9GMH Dimms... sorry :-/
D9GMH : 333MHz C5 1.8V Micron certified
D9GKX : 400MHz C5 1.8V Micron certified
I think that D9GKX are better for high frequency.
For low timings, I dunno
i don't think you can say GKX is 'better' than GMH
It all comes down to the binning of the IC's in my opinion.
true, but gkx has a higher speed bin out of micron's fab, so on average, it *should* perform better than gmh :toast:Quote:

Personally I prefer D9GMH.

Gskill @ 800 CL3 2,1 V
@ 2,4 CL4 both goes to 1070
So do A-Data's EE Vitesta 2GB PC2-8000. The Super Talent is a great buy for $275US~ or whatever it retails for now though.Quote:

8000 = D9GKX
6400 = D9GMH
next week I will get 2GBGA 6400s with 3-4-3-8
I think they have D9GKX too
Looks like some 8000 is going on my conroe shopping list then. Can't wait to get it all together.
but the 8000 cost a little bit more than the 6400 ;) but the Performance is not so far away between this 2 Kits, the most D9GMH can reach 1000 CL4
D9GMH is very good. Most do 1000-1080C4 at 2.2-2.4vQuote:

I have no idea about d9's and intel timings so im totally lost
I tried 4-4-3-8-14-16 no good :P
Well, not all D9GMH can do 500MHz C4 at 2.4V. I'm currently testing the OCZ PC2-6400 SOE Urban Elite 2GB kit and it does 500MHz C4 at 2.5V only. FYI, these OCZ modules comes with D9GMH too.
Max clock is at 565MHz C5 at 2.5V which was Prime stable for over 8 hours.
I also got another D9GMH kit (OCZ PC2-8K VX2) and it does 500MHz C4 at 2.3V only. However, max clock is only at 550MHz C5 at 2.4V.
Its all about the binning, I guess... :fact:
Edit: Above results were based on AM2 platform
Hey Kabauterman where are you getting the 2GBGA with these chips?
My D9GMH can do 500MHz 4-4-4-4 with only 2.15v.Quote:

I remember finding the first wall around 325MHz. A friend of mine gets easely up to 350MHz with his DS3.
Maybe it's a good thing it died, I'm hoping to get a better one in return.
With DS3 it seems important to loosen on memory timings in order to achieve high FSB.
500MHz CL4 at 2.15V?Quote:

does anyone know what ic's the Crucial Ballistix PC2-6400 2x1gb uses?
i have now 2GB Supertalent PC2-8000 CL5 (D9GKX?), they do 500Mhz 4-4-4-8 @ 2.05v Memtest stable :toast:
Nope... Those were samples... I didn't say I paid for them, did I? :p:Quote:

I searched online and saw one going for $290 only, but Newegg is selling them at $320! :eek:
They look cool, right?

Ok well I bit the bullet and ordered the OCZ 7200 to go with my E6700 and P5B Deluxe, ill be posting results soon.
i don't want to void my warranty by taking off the heatspreaders. will crucial be able to tell? also if i run them at like 2.4v(warranted for 2.2v)will they be able to tell?i only want to take a peak at them;)Quote:

i personally dont care which is better but if gigabyte cant fix the gskill HZ issue then this board is history.
i have no need for a board that cant even run with one of the top selling ddr 2 kits on the market.
The 7200 should do 4-4-3 @ 1100 :)Quote:

The OCZ are in my local store, but a little more expensive - I like the ease of a local route, but not if there is something better for less $$ on the market, decisions... I'm thinking the GBGA's at the moment though, and fingers crossed i'll be able to keep the cas3 rating for a few extra mhz. I won't be pushing the purchase button until I can get the mobo/cpu from the same store though :) the GBGA's are around ÂĢ30 GBP cheaper...

Any luck with 1100 4-4-3?
Yup. But to be honest, I forget the voltage I used. I -believe- it was 2.6v.Quote:

Im also impressed..
Thems some good sticks ya got yurself there son...
And ur 420th pot at that.. wut r the odds??
God must want ya to be doin somethin @ a particular time today, hmmmm?
Yeah, I'd say they are very good. They keep up to the VX2 in every way. Running 570MHz 4-4-4 atm... it's 95% stable, but requires 2.75v.
I wonder if the OEM Micron modules will overclock as good as performance ones from OCZ/G.Skill/Team/etc.....
found some Micron DDR800 CL5 modules with D9GKX oin them for a very cheap price... still thinking whether to buy it or not.
worth a shot? they may do well, and if not, you can always just sell them again, and know more about what's good and what's not :p:
Yeah, I'd say give it a shot if the price is right. The DDR2-800 Super Talents had GKX and they kicked serious ass.
Can anyone else confirm the above information?Quote:

decent gmh should do 1000 easy. with the right mix of volts that is
If D9GMH doesn't go past 1000MHz @2.3~2.4V the first suspect should be the mobo.
I wouldnt know my mobo max's @ 460ish with my D9's :(
4-4-3 though 2.1V
With 2.2v you should pass it easelyQuote:

i can do ddr2-600 with 2.2v.. although with what appear to be slightly better than average sticks. it's all about your luck, because remember that D9GMH is a 333mhz (ddr2-667) part coming out of micron's fab.. they just have pretty good yields :p:Quote:

2.2v~2.3v should be all you need.
Mine are most of the time at 533MHz or 667MHz cas3 (vmem 1.8v)
My Team D9GMH run best at 2.25v - they are the 3-3-3-8 667's. They run 24/7 at 504mhz (DDR2-1008) at 4-4-4-11 (SPD). I've gotten them up to 1100 at 2.35v 5-5-5-13 but I didn't try any higher as I can't seem to run stable past 4.05Ghz (CPU) or 506FSB.
I also have a set of Team 800 4-4-4-10's that need 1.35v to run semi-stable at 502mhz - I don't know what they max out at. They're fast but not nearly as stable as my 667 3-3-3-8's.
Both sets are D9GMH!!
just go to micron's website... there's an FBGA decoder:Quote:

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!!
Revv23, D9GCT

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).
:confused: Any idea what chip is used in CELL SHOCK PC6400 4-4-4-12?
I saw somewhere the price for D9GCT, GMH and GKX chip...
Can anyone help me finding this post ?
From what i read D9GMH for 6400, D9GMH or D9GKX for 8000 C5 and D9GKX for 8000 C4.Quote:

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?
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 :stick:
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 :toast:
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...Quote:

Well, my fingers are crossed. :D .
For the record G.S. Tech reccomends no higher then 2.4 for 24/7 IIRC
Micron seem to have quite lazy employees working in their "binning department" ;)
These modules are based on MT47H64M8B6-37E (3.7ns, D9GCT) icīs 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.
:D
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..
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)
^^^HMMM verrrry interesting^^^
Ive been trying to figure this out forever, thanks for putting this into perspective..
This "inside info", is already well known.Quote:

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)Quote:
