New Micron 1066mhz CL7 D9JKH HQ-187E available

[Don_Dan]

Initial results are good, to be honest better than I had expected.
1168 at 2.0V isn't bad at all, from their characteristics they seem to be very similar to DDR3 indeed.
Have you tested CL5?


Well, now it's quite tempting, considering a 2GB kit isn't that expensive... But I must not buy new RAM...

Please don't post very good results or I will have to spend some money again....

[Lestat]

the price doesnt matcht he current offerings of Ballistix 1066...
not sure why you would pay for CAS7 1066 when you can buy CAS 5 for $30 cheaper!
ALTHOUGH the 1.8v is quite nice.


someone take their D9 GMH or GKX and run it 1066 CAS7 (7-7-7-15) and see if they will run 1.8v


dont worry about overclocking right now guys just do a comparison of the 1066 CL7 to 1066 CL5 in terms of Everst RAM Speed.
see how much your performance goes down the toilet.....
although being where we are,, overclocking is a big thing.

how does ddr2 1200+mhz 4x2gb sticks sound to you? Might very well be possible with these Or I hope Whether the relaxed timings are worth it is another question, I think we'll be seeing some better performance than the stated stocks..

[Lestat]

i am rather shocked to see micron using non micron chips to be honest.
i see someone said they WERE using some other stuff and i have a set of the orange Ballistix DDR2800 and i can guarentee they are not D9 or are a really funky d9. just from their overclocking and the fact they hate anything over 2.1v

its like for using chevy parts in their cars...


4x2gb sticks would be nice but us useless as its been provne time and time again under vista64 and xp64 for anyone not running some sort of a massive server.

plus you would be hard pressed to find a system that can handle 4x2gb sticks.
whether they mfg of the mobo says it can handle 8gb of ram or not is bogus, the systems just cant handle it, be it power or northbridge or whatever...
admittedly poeple here have proven it can be done but it's not an easy task for most boards.
plus the lack of 64bit programs and STILL the lack of proper driver support or equal support as the 32bit drivers have

but anyways i am blabbering i want to see some everest benches to show bandwidth compared to 1066 ram @ CAS5

Lestat, you must not have read this thread through, and regarding your ballistix...you are way out of the loop.

These are using 'new' 78nm Micron D9 chips that are double density and in general tend not to clock as well as the older D9's that we are all familiar with. They also tend not to like tight timings.

Good luck getting 1066 Cas 7 to work on an intel board, and good luck getting the new Ballistix to actually run 1066!

I can't even get these sticks to run cas 7, not sure if it's just this board or all/most intel boards in general.

D9GMH can't run cas 6 or cas 7, it only supports cas 3, 4 and 5.

Cas 5 runs to around 1040mhz on these, but that's expected. Cas 5 on these sticks is like cas 3 on cas 5 binned IC's. It also could be an issue with the subtimings, as I have very limited manual subtimings on this board, and the spd revision the sticks use is newer than the spd my board supports.

This difference between 6-5-5-18 and 5-5-5-18 is pretty negligible. I'll get some screenies in a few of some benches.

you forgot to say they tend to die real quick lol

[Hutch]

I'm stunned, no difference between 6-5-5-18 and 5-5-5-18!

*note if you're wondering about why the SPD says PC-8800 555mhz, it's because of the difference in SPD revisions. The SPD byte value on SPD 13 of '18' (1.8ns) is 533mhz, on the board SPD rev 12, the value '18' is 1.8ns (555mhz.) There is no 533mhz spd value on spd rev 12 (or 1.2.)

i have been out of the loop man, i been real busy at work and really haven't had time or energy to do a lot of research.

so if my comments seem uneducated (about my own hardware) then you are correct.

2x2gb 1066 CL7 1.8v

WAYYYYYYY too expensive.....

hutch whats the difference in speeds between the new ram and the stuff in your sig,, just out of curiosity?

No worries man, I apologize if I seemed insulting.

[Hutch]

The ram in my sig, as well as another set of 512mb Ballistix are as good as dead. They need atleast 2.3V to boot and they won't run faster than 667mhz 5-5-5-15. It takes about an hour of fiddling just to get them to post.

They were great before though, hit 1000mhz cas 3 with the set in my sig, 2.81V.

4x2gb sticks would be nice but us useless as its been provne time and time again under vista64 and xp64 for anyone not running some sort of a massive server.

Theres a market for pretty much everything . Especially, if your motherboard cant run 4 sticks properly, guess 2gb modules are the only way to get 4 gb :p And there should be quite a difference between 2 and 4gigs on 64bit no? Powerchips are all nice and cool, but if these offer similar performance, why not .
(other than the price atm :X)

I'm stunned, no difference between 6-5-5-18 and 5-5-5-18!

Hmm is it just me or the screenies are identical? Can it be you screenshot the 5-5-5-18 2 times? or is the proxy at work being weird oO.
Anyway, is the difference in bandwidth between 5-5-5-18 and 6-5-5-18 supposed to be big? Cant try out right now.. Was under the impression PL is way more of a factor.. Is a PL of 6 physically possible at 6-x-x-x :x. Never had the time to tweak my mobo much

PS sorry if I make some weird conclusion, am pretty new to the developments over the last few years

[Monstru]

Guys...are you talking about DDR2 here? Because I had the feeling that this thread is about DDR3......

Working 4x2Gb has absolutely no point, so that would not be the reason for which they produced these new chips. So...I must say....Unless they run >1500 CAS 7....they are pretty much useless.....

[saaya]

yup
i got a nice collection of d9gmh saya and they not created equal lol

yeah, definately... for some batches gmh and gkx are almost identical when you oc them, for some batches theres a big difference and all chips are good... some batches oc better with cas4 than with cas5, lol...
the last batches all clocked very well with cas5 iirc
the older batches oced better with cas4

at least thats the experience i made...

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?

well, you wont believe it, but micron isnt as aware of how well their chips clock as we are... their priority is after all the OEM business which means they need chips that have good yields at the jedec timings and speeds, with as low voltage and power consumption as possible...

what makes micron a good ocing chips mfg is that they always aim to reach the highest possible jedec spec or surpass it though, while most other chips makers usually only want to make chips that barely run the volume jedec specs like ddr2 667 555 for as cheap as possible.

hutch, oh come on!
you bought high speed mem and try to push it on a freq limited board? :P
christ, all this waiting for your results and then this, meh!
i want my money back!

hope you can find a decent board asap

yup older batches are better with cas 4 for me
the last good batches dont like cas 4 but crazy on cas 5 i got mine to 1240mhz 2.03v, cas 4 needs way too much voltage 2.2+ after 1000mhz

In the first screenshot I didn't include the benchmark for 6-5-5-18. The 2nd one included the benchmark and the 3rd one included the benchmark with timings set at 5-5-5-18.

Going from PL 8 to PL 7 yielded a boost of 250mb/s on the read score and -3ns on the latency. I hadn't tweaked the timings at all there. The PL can probably be brought down to 5 or 6 at this FSB.

I think Hutch is going to bring these sticks over to my place for some DFI X38 action on tuesday. I think that would be as good as it gets for DDR2 memory overclocking nowadays.

[Khalmyr]

nice, i'm waiting for your results

really excited to see these new chips, hope we can get some 1400+ clocks =D

Great, I'm patiently awaiting the results. Be sure to add your best results to your DDR2 database, and btw, maybe you could update it....

[saaya]

good to hear alex!
try not to blow up your board until the weekend then
no benching for you all week!

[EnJoY]

We both got too tied up to do anything with them today, but I guess we'll have to try for another day since you guys are clammering for some more numbers.

[Crashtestdummy]

hi
ive got a kit of these crucials too. made some quick test on a gigabyte p35 ds3 and the results are weird. no matter whats the voltage from 1.72 to 2.25 i always get stuck at (2:3 ratio) 1142 cl7. cl6 is slightly weaker, but increased voltage wont help either.
any suggestions? i was expecting these modules to go crazy even on cl5, but it has been quite a disappointment so far. will try different ratios, i hope that will help. d9gxx chips liked 2:3, but these are not only a bit different from those... maybe they like something else.

the spd is useless for this ram since its rated 1110 cl5 1.8v, of course it wont even boot up at these settings.

[Neuuubeh]

so whats happening with these chips
