New Micron 1066mhz CL7 D9JKH HQ-187E available

[Hutch]

Has anyone tested these yet?

kingston and some1 else also have kits of this out

The Kingston kit has the Elpida 1066mhz Cas 7 ICs.

[zsamz_]

are you seriously interssted in cas7 ddr2 lol

[-n7-]

Interesting.

I wish there was something like this in 2 GB form though...

BTW, do you know what IC the 2x2 Ballistix kits use?

2GB DIMMs and its respective kit are also available

They do have these sticks in 2GB form. The 2x2GB Ballistix use powerchip ICs, although it seems like they may start using D9JKH soon.

[zanzabar]

Are you a complete moron? Do you not realize that D9GMH is rated at 667mhz Cas 5? D9JKH is binned higher than D9GMH.

You may want to do a little research before you speak, asshat.

do u realize that thats the same nS bin

[Hutch]

do u realize that thats the same nS bin

D9JKH = (7/266.67)(100) = 2.62ns
D9HCD = (6/200.00)(100) = 3.00ns
D9GKX = (5/200.00)(100) = 2.50ns
D9GMH = (5/166.67)(100) = 3.00ns
D9GCT = (4/133.33)(100) = 3.33ns

Lower = better

Someone please correct me if I'm wrong.

[Jupiler]

Thread cleaned.


Don't make me step in a second time.

[Hutch]

Just ordered the 2x1GB kit of them from Crucial. They'll be here tomorrow!

in theory... yes
i havent seen any reviews or results of those new huge cas ddr2 chips tho, would be interesting to see how they perform, and especially if they really need cas7 or if cas6 works as well. but even cas6 would be quite high..

[EniGmA1987]

It would be interesting though to find out if we can get them to somewhere around DDR1400 on CAS7 or even 6. Some companies sell (or used to sell) 1GB sticks that did 1066 @ 2.1v with GMH chips. Seeing as how GMH is actually rated much lower, these new JKH chips might be able to clock pretty high.

That's what I'm hoping for. I just can't see Micron ditching the D9G/MH/KX for nothing. I was skimming through the data sheets last night and they seem to be more energy efficient than the Rev D chips. The specs are similar to GKX, except faster (skew settings ect.) Temp range is from 0-85c which is the same as the rev D series. Rev D series had a max voltage of 3.6V, not sure what the max voltage of the new chips are though.

I certanly hope so, may be another reason not to ungrade to ddr3 yet.

Micron is only interested in production cost and efficiency, I don't think they care much about overclocking. Up to now the new chip weren't good, but maybe these are different. Keep us posted!

are you seriously interssted in cas7 ddr2 lol

lol agree

i talked to some micron engineers in a conf call recently and i got quite the opposite impression

but saying some GMH chips oced great so theese new chips will oc a lot as well is complete bs guys

thats like saying c2d cpus can reach 100% ocs, so all intel cpus can probably reach a 100% oc

yup
i got a nice collection of d9gmh saya and they not created equal lol
i got 4 sticks of ballistix "d9gmh" that are better than my d9gkx they doin 1200+ with 2.03v lol 5 months n they rockin
n my mushkin xp2 pc2-8500 never lasted more than 2 months per set lost 3 last year lol n the new sets gave me errors day 1
my kingston value d9ghm still goin strong 18 months
i got no faith in the binners i beleive in luck

Cool, I didn't know that! But still, why did they stop producing GMH/GCT/etc, is there a good replacement for them that we can expect from Micron?

The new chips are single sided, so essentially they can double the module capacity without making significant changes.

Everyone was mad when Micron ditched the fat bodies for the Rev D chips. It took a little while for people to realize that the Rev D chips (D9GMH/KX) were better than the fat bodies. Once that was discovered everyone was happy.

The ram should be here within the hour. I'll keep you all updated. Hopefully my board detects them properly, as they do use a new SPD revision (1.3 I believe.)

[Neuuubeh]

ow come on, make that mailman move faster I'm dying here :p
NEEDS RESULTS ASAP

pretty please?

[Hutch]

Having some issues with them. The SPD settings are a little screwy because my bios hasn't had the SPD updated. My board also sucks and won't clock ram past 1168mhz no matter what. I was able to get my old Ballistix up to 1168mhz cas 4 and cas 5 on this board. These new sticks are brick walling at 1168mhz also. They don't like tight timings (as I expected, considering they're binned for cas 7.) They to be very similar to DDR3.

1168mhz 6-6-6-18 (stock voltage, 1.87V.)

1168mhz 6-5-5-15 (2.0V, haven't tested lower voltage though.)

I need to test these on a better board that can clock ram real well to get more accurate results. I suspect that these will do well over 1400mhz cas 6 and or 7 with minimal voltage with the right motherboard.

[Neuuubeh]

sounds interesting to me :P. I gotta look around for a kit of those, more interested in the 2gb sticks..
someone should test them on a DFI board

[EniGmA1987]

1168 @ 6-6-6 isnt bad at all, but it isnt great either. It would be nice to see these sticks on a good P35 board with 2.2-2.4 volts to see what they can really do.
