Help with distinguishing two models of Corsair RAM

[tulx]

Hello techies!

I'm upgrading my system with set of new CPU+MoBo+RAM.

The CPU is a Phenom II 970 BE, the MoBo is a Asus Crosshair 4, and the RAM, well - Corsair, 3x2GB, to be more specific, but there are two very similar models.
One is called TR3X6G1600C8 (link to an online shop: http://www.newegg.com/Product/Product.aspx?Item=N82E16820145236&cm_re=TR3X6G1600C8-_-20-145-236-_-Product ), the other is called TR3X6G1600C8D (notice the "D"), (and a link in the same shop: http://www.newegg.com/Product/Product.aspx?Item=N82E16820145224&cm_re=TR3X6G1600C8-_-20-145-224-_-Product)

The "D" version costs about 20€ more. Is the passive cooling the only diference here? The Asus board comptability file lists only the "D" version, although I found both in various sources around the net.
Can someone try to clear things up a bit for me here?
Thanks!

PS - changed the links. Something was broken.

^ Do NOT use EITHER, you have a Dual/Quad DDR3 MOBO which requires sets of 2 or 4 and not Tri Channel (3).

Corsair Tested - http://www.corsair.com/configurator/product_results.aspx?id=1575023

CORSAIR DOMINATOR 4GB (2 x 2GB) DDR3 1600 (PC3 12800) CMP4GX3M2A1600C9 - http://www.newegg.com/Product/Product.aspx?Item=N82E16820145296

Good Luck on your build!

Oh, I see. Thanks!

PS - isn't 9-9-9 a rather high latency? Or is the performance difference negligabe?

PPS - I found this http://www.newegg.com/Product/Product.aspx?Item=N82E16820148304&Tpk=BL25664BN1337 How about 4 of those? That should work, right?

Same IC's edit: for what I posted for you above Corsair + {CAS}; interesting data look at the Speeds & CAS info:

Comparison Module #1: Mushkin Redline 996805 6-8-6-24 1600MHz
Comparison Module #2: G.Skill Pi Series 7-8-7-24 1600MHz
Comparison Module #3: Mushkin 998687 8-9-8-24 1866MHz
Comparison Module #4: Corsair Dominator TR3X6G1600C8D 8-8-8-24 1600MHz
Comparison Module #5: Kingston HyperX T1 9-9-9-27 1600MHz
Comparison Module #6: Mushkin Blackline 998677B 7-7-7-20 1333MHz
Comparison Module #7: Patriot Viper II Sector 7 9-9-9-27 1800MHz

PM same info - oopsy.

That looks promising indeed, but, oddly enough, the specific model ( TR3X6G1600C8D ) shows up in the compatability list provided by Asus in form of 1 DIMM support... And the CMP4GX3M2A1600C9 wasn't listed at all...

 

[jaquith]

Ignore the 'graph' {mine} in the sense of Comparison Module #1...#7 - NONE of them are compatible with your MOBO; the 'comparisons' are for the RAM IC used ONLY. They are all i7/Tri Channel Kits. {{ The IC on the TR3X6G1600C8D are the SAME as the IC for the CMP4GX3M2A1600C9 }} I recommended. The 'graph' is for 'demonstration' purposes of CAS, Speed, and IC used in the RAM...

CMP4GX3M2A1600C9 is WHAT you need to use.

 

[tulx]

Oh, heh. Right.

Got the point now.
I'll start off with 2x2GB and see how much the system uses. I'll get the other 4GB at some point later, probably. Thanks for the info!
