Corsair TWIN3X2048-1800C7DF --> Setup & OCing on P5K3-D, P35T-DQ6 and Blitz Extreme!!

Hi all,

The time has come and Corsair has introduced a full line of high performance and low-latency (as for 3rd generation DRAM, that is) of DDR3 memory products:

- TWIN3X2048-1600C7DHX G --> 2x1GB kit, DDR3-1600 7-7-7-20 @ 1.80v
- TWIN3X2048-1800C7DF G "Dominator" --> 2x1GB kit, DDR3-1800 7-7-7-20 @ 2.00v
- TWIN3X4096-1600C7DHX G --> 2x2GB kit, DDR3-1600, 7-7-7-20 @ 1.90v

Some of you might have already had a chance to take a look at preview I posted two months ago of what Micron DDR3 DRAM has to offer. This time, I wanted to come back and share some of my experiences with our production memory - a part of Corsair's Dominator line of high performance memory - TWIN3X2048-1800C7DF G.

The black heatsink and sticker indicates that there is the Dominator in town :)

Now, I would like to provide those of you interested with some information as to what's up with all that "new Z9" buzz that reviewers and readers have been creating.
"Micron Z9" is not really some magic new DDR3 chip that Micron cooked up in their fabs. Those 2 letters have been around since 1st generation of Micron DDR DRAM in FGBA package and only indicate that chip is in ES stage. In other words, Z9xxx prefix tells us that we're dealing with Engineering Sample of FBGA DDR memory, be it DDR or DDR2 or DDR3. Those are usually sent to motherboard makers, OEMs and memory module manufacturers in the early stages of evaluation and validation process. Then comes Commercial Sample (CS), which FBGA code starts with D9xxx prefix. This is what would mostly end up on modules shipped to end-users.

To make things a bit clearer, below is the list of Micron 1GBit DDR3 speed grades with corresponding FBGA codes for ES and CS chips:

Code:

Micron 1Gbit DRAM, 128Mx8, 78nm, MT41J128M8BY FBGA codes for Engineering (ES) and Commercial samples (CS) Speed grade | ES DRAM | CS DRAM ---------------------------------------- -25E 800 5-5-5 | Z9HWW | D9GTP -25 800 6-6-6 | Z9HWV | D9GTN -187E 1066 7-7-7 | Z9HWQ | D9GTR -187 1066 8-8-8 | Z9HWT | D9GTQ -15F 1333 8-8-8 | Z9HWS | D9GTT -15E 1333 9-9-9 | Z9HWR | D9GTS -15 1333 10-10-10 | Z9HZM | D9HZL

... and a picture for your hungry eyes. Currently, all shipping 1600C7DHX G and 1800C7DF G are built with Micron D9GTR chips.

So, what's this tread is about. Well, good question! I wanted to share some of the "how-to" regarding configuring and overclocking this awesome set of memory on most popular DDR3 motherboards that are now available to enthusiasts. Currently, my list includes:

- Asus P5K3 Deluxe (Intel P35)
- Gigabyte P35T-DQ6 (Intel P35)
- Asus Blitz Extreme (Intel P35)

In quick summary, I took 3 motherboards and set them up in order to ensure proper and stable operation at 1800C7. Then our lab memory diagnostic tests were performed, with subsequent boot to Windows. There, setups were taken for a ride on 24hrs ORTHOS tour and several most popular among overclocking community :buddies: benchmarks.

The fun side of this thread is that at the same time you will get to see how all those different motherboards stack up against each other in therms of performance at stock 1800C7. For the lazy-mouse-clickers :p: below is the comparison chart breaking down benchmarks results achieved on all three motherboards:

Ufff, aren't you dizzy from clicking and looking at the screenshots yet? :lol:

I hope, that this will be helpful to those of you looking into adopting a DDR3 system along with a set of Corsair's fine high performance memory based on Micron 1GBit DDR3 chips.

Thank you for your attention and come back often! If you have any questions and/or requests then shoot me a line here and I will comply :)

Well, that's not entirely up to us, as one has to deal with DRAM component prices. Just to give you an idea, Micron's 1Gbit DDR3 ICs are roughly 4 times more expensive than it's 1Gbit DDR2 counterpart. So, imagine how much wiggle room there is left...

Yes, 2x2GB kit is part of the line as well and it performs quite well, with some very decent headroom left in there.

Heya! Well, P35T-DQ6 seem to really work very well as long as F3i BIOS is flashed. One important setting that seems to "make-or-break" this board at high frequences is "DRAM DLL Settings". It defaults to "Option 1" and has to be changed to "Option 2". Otherwise, at least from my experience, system would constantly lock-up during our hardware diagnostic tests.

Oh man, I cant wait, I simply cant wait for the prices to come down. I am dying to get that kit. Good job corsair :clap:

Bachus can I ask a question? What kind of FSB speeds do we need to fully take advantage of 1600+ DDR3 memory?

Thank you! Well, naturally 1600MHz FSB (400Mhz) is currently the lowest bus speed you can run DDR3-1600 memory at. It's not very easy to determine if higher bus speed gives an advantage when you're trying to stay at the same CPU speed. E.g. for DDR3-1600 you could run either 400MHz FSB at 1:2 ratio or 480Mhz FSB at 3:5 ratio. However there is no way you can keep the same CPU speed at those above mentioned FSB speeds - 400x9=3600MHz and 480x8=3880MHz or even 400x7=2400MHz and 480x6=2880Mhz. That makes apples-to-apples comparison not quite possible. But if one has a CPU that maxes out at 3600Mhz and DDR3 that pulls DDR3-1800, I would naturally prefer 450x8 at 1:2 (resulting in e.g DDR3-1800C7) rather than 400x9 at 1:2 (that is DDR3-1600C7).

Well, time will tell if this will be a material for another "what's better - D9GMH or D9GKX" that some enthusiasts have been asking in regards of Micron DDR2 chips.

Looks pretty good to me... As for your title, I'd shoot a PM to one of the admins - e.g. njkid32. He'll be happy to help you!

*************

One thing I'd like to mention to those of you interested in playing with tRCD and tRP is that a vast majority of 1800C7DF and 1600C7DHX should allow to tighthen those timings to tRCD=6 and tRP=6 without a voltage bump. However we decided not to make it an official spec and leave up to you to mess around with it :)

At those lower latencies there is a few seconds to gain in e.g. SuperPi 32M, which we all like to bench here. Below, side-by-side on P5K3 Deluxe. Just as above, no memory settings has been altered in Windows and Memset window is opened just to provide additional info.

I really wonders over the price though, it costs tooo much, even for an OC freak! Its over 6000kr in sweden for 2GB, thats about 870 dollars.

Im a "new" freak like to play with new stuff, I generally buy to much computer parts, but really those prices are hiigh! And i DO want it with my X38 , and i REALLY do hope the prices will fall dramatically.
