New 2x2GB DDR2 Dominator ICs

[18 is # 1]

It appears there are some new ICs on the Dominators. The first 2x2GB kits were all Powerchips. Take a look at the list they finally updated (I've been asking since Febuary).

Anybody have experience with these versions?

Hmm Elpida ICs. I wonder if they are lower voltage

[zsamz_]

i know for a fact Elpida.C is garbage

Who cares as long as they overclock well?
IC vendors are more conscious about the performance quality of their chips these days.

WTF Micron?!

D9JKH like the epic fail Crucials, or what else i wonder.

Corsair & their insane IC switching...you never know what's in 'em.

micron on 2x2gb ?

i thoght that micron ics are only on 2x1gb kits...

old 2x2gb dominator can run at 1140mhz in oc, this new, how can it do?

Fixed it for you!

Most likely one of the Micron chips is D9JKH, but what's the other one?

Micron makes many ICs, a lot more than their famous D9GMH chips.
If I recall correctly their first 1GBit IC was D9GSV, very good stuff, which was replaced by D9HNH and D9HNL. And then there were the infamous D9JKH...

570MHz is typical PSC territory by the way!

[devil_mcry]

ok i understood
but for example, what ics have gskill pi 9600 ?

they have promos

I doubt we'll ever really know, as the newer DDR2 ICs from them are unmarked (like D9JKH).

Either way, i'd rather have Elpida that can do 1100-1250 @ 1.8v TBH...

Sure you will, I only waited six months after asking......

D9JKH isn't bad actually - most 4gb ballistix kits with those chips can do 1150 c5 and 1200 c6 with little to no difference between cl5 and cl6 in performance
before the new gskill 9600pi and new elpida chips intro they were just about the most overclockable sticks around

dont mix them up with D9HNL which really were an epic fail not being able to hit 1000 no matter what

D9GSV were rather nice too, but if you wanted to push over 1100 they needed about 2.3v which caused them to die very quickly

Yeah, I guess D9JKH is not bad for "normal" users, but seriously 600MHz CL6...

D9GSV or even D9HBD were their best 1GBit ICs in my opinion, they were reacting almost like D9GMH to some extent and they die just like them!

but what can it do?

can d9gsb or d9hbd run over 1200 cl5 d.u.? and how kit have this ics?

[Don_Dan]

Oh sorry, I made a typo, it must be D9GSV, I corrected it in the other post.

If you're interested in what they can do, here is a review by Eldonko.
You can see that this review was done more than 2 years ago, back then it was very good stuff, but this RAM won't do 600MHz and even finding a kit that uses these chips today is very hard. You are better off with kits using new ICs like the low voltage OCZ or G.Skill's 9600 PI.

i have read, very interesting...

i didn't know these ics micron, gmh and gkx are more famous i think ...

thanks for the esplanation

you better of gettin lucky with cheap crucial value 2x2

Eh, i can't really agree.

I bought my first 2x2 GB kit of Mushkin right after they'd switched their kits over to PSC, well before many people were even considering 2x2 GB kits.

For their time, no doubt D9GSV/HBD were good, but they were all insanely expensive & needed tons of voltage to get anywhere.

Considering that the only benefits of the slightly better CAS 4 results [than PSC] are when using an nForce platform, i don't see how they were really best for anything.

Even the early PSC 2x2 GB kits could do better MHz @ CAS 5 than D9GSV could, which is what Intel chipsets do best with anyway.
And they did so with far less vDIMM & much better prices.

[Don_Dan]

That's why I said, it was Micron's best 1GBit IC, you can't compare them with Elpida rev. D or high binned ProMos or PSC, those chips are better for sure, but we have also seen 2 years of development since those D9GSV kits were released by Mushkin. When they were new I was still messing with my Striker Extreme and as you said, they were quite good on the nForce platform, as you could do some nice 6GB setups with 2 sticks of D9GSV and 2 sticks of normal D9GMH/D9GKX. You've got a valid point with them being insanely expensive though, but well, stock was limited...

I hope you can agree with that, but still, it's unfair to compare D9GSV to PSC, since we are talking about two entirely different DDR2-IC generations that were built and tuned for different chipsets.

[Ket]

I agree with n7, 1200+MHz @ 1.8v is far more appealing than 1200-1300MHz @ 2.3-2.4v or more. Its why I have my precious OCZ 9200 Platinums, for once I haven't been burned by OCZ

[Don_Dan]

Sure it's better to have high frequencies at low voltages, but that's not my point. This was just the best when they were released, because these new ICs like PSC or Elpida would not be possible with the further development of the manufacturing processes.

I think we should end this discussion now!

[devil_mcry]

but can actual ics of dominator run realy to 1142mhz?

[Don_Dan]

Nothing is ever guaranteed when overclocking.

My personal opinion:
PSC: most likely not, most crap out at 560MHz CL5
Elpida: don't think so, as they don't use the same chips OCZ uses
Micron: the only IC that could "possibly" even do 600MHz with CL6

therefore if these ram can run at 1140mhz cl5, it has micron jkh...
correct?

Eh, i wouldn't say that.

Extremely good (best of the best) PSC can do 1150+.
We don't know much about what version of Elpida they are using, but we know good Elpida can do very well.

The way to know is to look at the revision.
It'll be listed on your heatspreaders.

Now if you haven't bought it yet, obviously you won't know till it comes in.

Considering how cheap the nicely binned Elpida is that OCZ is using in their LV kits, i see zero reasons to be considering Dominators that may or may not be decent ICs.
