Micron D9 GMH\GKX\JKH etc club

[Ket]

I haven't been able to find a thread like this doing a quick search, so here goes. This thread is exclusively for D9 owners (regardless of 3 letter suffix) to help D9 owners get the most from their sticks. On top of this I will also lay the offer on the table to modify any BIOS version I can to add better D9 compatibility, which should lead to better clocks. Note that I CANNOT help with BIOS mods if your board happens to use an AWARD BIOS. If your board uses a AMI BIOS then I can help.

To help people with information try to make sure your screenshots include CPU-Z, Memset and mention what voltage your sticks are using. If you wish to "prove" your OC stable, dual SPI 32M is mandatory.

With all that said, I'll kick things off with what I'm testing right now.

Cellshock 2x1GB D9JKX @ 2.2v 1200MHz

hmm, I always thoght micron's ics was GKX not a JKX

and what is a JKH ?

Dh'o! typo. I don't exactly know what a JKH is, its just listed in the P5Q Premium QVL list simply as "MICRON ...D9JKH".

D9JKH is a 1Gbit (128Mx8) DDR2 chip binned at DDR2-1066 by Micron.
It is being used primarily on singlesided 1GB modules or doublesided 2GB modules.

My D9JKH... Pretty bad on my P35 board, but I'm sure they're better on the newer AMD chipsets that support DDR2-1066 @ 1.8V.

Voltage is only 2.0V. They don't scale much higher @ cas 5 with more voltage...

ohh, those sh**ty ics

thanks for the info

I think Fatalbert meant for OCing what JKH is like

Well, that depends on whether they are used on a 1GB or 2GB DIMM. As we all know, 2GB DIMMs overclock a lot less.
But indeed, even on 1GB DIMMs they are not the best out there.

if its that, then its the retimed NLH and other revE and its not vary stable or reliable, its like qib ddr3 crossed with hynx ddr2. IMO it may not reflect the new binning im just salty about my viper 800mhz cas4 that clocks vary bad on every board that ive tried it on (i was trying to offload them on some1 but i couldent do it)


what do your mods do to the bioses i know that i have the award bios im just wondering

[FatAlbert]

in my opinion, one of the worse ics for oc

imo

G.Skill Pi have got the best ics if we are talking about OC and 2x2 mems

[whe3ls]

i have an old stick of pc 4300 d9 hnh 128x8 it hit 900 mhz with 6 8 8 10 timmings

[fatguy1992]

Here's the best I have done with my Corsair Dominators PC2-8500, they have D9GMH chips.

Best 5-5-5 Overclock

650MHz 5-5-5-12 - 2.5v

I had the the Tras @ 5 just after this screen shot but I didn't screen shot.

Best 4-4-4 Overclock

600MHz 4-4-4-1 - 2.5v


Best 3-3-3 Overclock

450 3-3-3-9 - 2.5v

If its any use to anyone as the subject has been kinda bought up I have 3 kits of memory kicking about I'm thinking of getting rid of. One of the kits is a Patriot 800MHz 4-4-4-12 kit. Tested in my old AW9D-Max I had the sticks did 1000MHz @ 2.2v (.1v less than Patriot state is needed) and had them booting right up to 1066MHz. I also have a Set of Geil Black Dragon 2x1GB 800MHz kit, again I had this kit doing 1000MHz @ 2.2v. Didn't really play with them much beyond that but I'm relatively sure their pretty solid sticks so likely have more to give. The last kit is a set of OCZ 2x1GB PC8500, this kit has booted 1143MHz, but I didn't really test this kit either. Yes I am a RAM nut

@ Zanzabar, my modded BIOS works on compatibility. At this time that includes better CPU support, better memory compatibility, most report much better OCs and quite a few people state my mBIOS to fix problems that are in vanilla BIOS releases.

How do i find out if my mobo has a AWARD bios and a AMI bios?

[Ket]

Look at the first POST screen with any boot logo you may have disabled

[fatguy1992]

Ok will do as soon as I restart

[Rone]

If that doesn't work out somehow, CPU-Z can tell you the same and you don't even have to reboot.
Open up the Mainboard tab and check the BIOS section. Next to ‘Brand’ it should say what kind of BIOS you have.

[fatguy1992]

OK thx, i have "American Megatrends Inc" so is that AMI?

[Ket]

OK thx, i have "American Megatrends Inc" so is that AMI?

Yep American Megatrends is AMI. FYI if anyone sees Pheonix at the first POST screen your BIOS is AWARD. The most reliable way to tell is by looking at the first POST screen, you can use CPU-Z or Everest something like that, but from time to time they do actually report the BIOS wrongly.

[Ket]

Heres what I'm testing atm, still 2.2v. Slowly figuring out what this mobo does and doesn't like.

Are all the Team Xtreem PC2-8500's that good?

[CryptiK]

No idea TBH, there aren't many results for the 8500's around, but I have seen another guy that hit 1350+ with them. I have 2 kits and they both can do 1333 on <2.3v but they are not SPI32M stable they'd need more voltage.

2.45v ballistix
i'm sure they can do better @ lower fsb

Wow nice results, you broke 12K! I want your mobo

[OC4/3]

Are all the Team Xtreem PC2-8500's that good?

Team Xtreem PC2-8500 is not bad.
Never really push my kit but it does:
1000mhz@2.05v-2.075v
1070mhz@2.3xxv
V shown is bios set
But my ram start to degrade

Here is what chip:


Good deal consider i pay ~US$100 or so
