Best form of D9?

[dunn2953]

i know there are at least 3 different forms of D9 (D9GMH, D9GKX, and D9GCT) but i have no idea which tends to work the best and was wondering if anyone could shed some light on this for me?

[MrRevhead]

From highest speed binned to lowest, D9GKX, D9GMH then D9GCT.

This is based on looking at the average results achieved from such IC's relative to the timings used.

[dunn2953]

thanks, does anyone know which sticks still use D9GKX?

EDIT: i just noticed something called D9HNL as well how does that fit into the mix?

[ozzimark]

HNL sucks for the most part. ;)

[dunn2953]

really crappy D9 wasn't aware that existed :)

[CedricFP]

Isn't HNL the 75nm stuff?

What about DQT? Weren't they the original fatbodies that were quite possibly the best clockers?

From my own knowledge, the GKX will eat up the volts happily and you could probably get higher clocks, but not much more so than GMH which, I think, has a better capacity for tighter timings.

There is some Geil / G.Skill / Super Talent ram that have GKX chips, but here in HK they are stupidly overpriced.

don't be mistaken. most of micron's "D9" chips suck. actually, many of them aren't even ddr2. it really is a bad name, since every chip they make that is put in fbga form has a code that starts with D9 unless it's still a pre-production part of sorts ;)

compared to the B6 chips (gmh, gkx and gct, and a few others, the only difference between them is binning btw. identical otherwise) the BT (fatbody, again, terribly named) chips are rather lame, since they don't have the same flexibility. they can do tight timings, but high mhz is serious challenge

Strange, in my experience GKX doesn't like voltage & clocks very well with tight timmings especially cas 3. GMH responds well to voltage and some well binned chips do cas 3. Older GMH were doing DDR2-1200 cas 4 with 2.3v-2.4v. Lately DDR2-1200 only seems to be possible with cas 5. GKX chips are more desired because they reach the same overclock's as GMH with less voltage & usually tighter timmings.

I thought the big appeal with GKX was that they could run on higher volts 24/7 much more happily than could GMH..

only the GMH lovin the volts as long as u got a fan on em
i runnin then 2.37 24/7 with 2 80mm fans n they cool to the touch

[Cupcake]

I had the exact same results with GMH and GKX , Both in the Gskill HZ 1000s

both died under 2.35 1150mhz after about 2 months , waiting on the replacement now

[fireice2]

are Buffalo Firestix DDR2-1000 2GB kits good overclockers?

[dunn2953]

i was wondering what a good 2x1gb set of D9GKX was preferably around $150 dollars?

[quake6]

Hmmm.What about Cellshock?

[The Nemesis]

If you can wait for these (http://www.newegg.com/Product/Product.aspx?Item=N82E16820227091), their right in your price range. Mine do DDR2-1200 @2.3v 32mb pi & 8 hours memtest stable & still under warranty at that voltage. I didn't test low cas yet but I can.

[dunn2953]

how about this (http://www.buy.com/retail/product.asp?sku=203469617&loc=101)?

[The Nemesis]

how about this (http://www.buy.com/retail/product.asp?sku=203469617&loc=101)?

chances of those being GKX are slim.

[dunn2953]

but for the price its a killer deal

[dunn2953]

its D9GMH

[The Nemesis]

Best D9GMH deal right now are these (http://www.newegg.com/Product/Product.aspx?Item=N82E16820146565) or these. (http://www.newegg.com/Product/Product.aspx?Item=N82E16820231065). The crucial are unbeatable with that rebate. My G. Skill do 800mhz cas3 2.3v & 850mhz cas3 2.44v

[dunn2953]

will that crucial DDR2-800 clock about the same as the DDR2-1066 if both are based on D9GMH or is the binning different?

[The Nemesis]

The binning is different I believe. Although my 8500 kit shows as a 6400 kit in cpu-z with 400Mhz & 533Mhz spd timmings.

[dunn2953]

i think ill spend the extra money and get the better binned ram, its only 20bucks more

I agree...may have the grab them before prices rise and hold onto them until the E6x50 CPU's are out to buy the rest of the rig.

[erwinz]

buy crucial 8500 :)

buy crucial 8500 :)
There is no way it can be worth it to spend $200+ when you can get nearly the same thing for $69...especially when the 8500 is just overclocked 6400.

my my, you put it so simply. the 6400 sticks are binned to 2.5ns at cas4, the 8500 sticks are binned to 1.875ns at cas5.. in reality, since it seems that they are almost always GMH based, they're both overclocked pc5300, if you want to put it that way ;)

[Soulburner]

Well I ordered a pair, I couldn't pass up the deal. I'll have 2 sets to test but they will sit for a while waiting for an E6750...and an IP35 Pro.

[quake6]

almost always GMH based...
Almost?What chips are on 5300/6400 modules?

Almost?What chips are on 5300/6400 modules?

so far all I've see are D9GMH. I don't think they used elipda in higher end models, although at one point, I think I remember hearing some people getting elipdas for their low end modules (but mixed chips and bins for value ram are expected) and I think the elipdas was due to a higher demand for D9GMH. The Ballistix 5300/6400 are GMH. And anyway, for the 5300, I haven't seen any non-D9 sticks do 667 mhz @ 3-3-3-8 at the voltage they recommend. The team xtreem are at those same timings :)

[quake6]

I saw HNL before a week on ballistix 6400/5300...Is it safe to buy it??

[ozzimark]

Almost?What chips are on 5300/6400 modules?

i say almost cause the 8500 sometimes has GKX :up:

[Yukon Trooper]

GM is usually very good. GK can get high clocks on lower voltage. I know some Buffalo has the GK in it.
