ThEButcheR Posted October 23, 2010 Share Posted October 23, 2010 Hi, I'm thinking of buying some new Dominator GT RAM for my new SR-2 rig. When I was looking on Newegg which RAM to buy, I've seen that there is a dualchannel RAM Kit @ 2133MHz, while the highest rated triplechannel Kit is running @ 2GHz. I was looking at: This Dualchannel Kit and this Triplechannel Kit. Now my question is: Can I buy 3 of these 4GB Kit's and run them in triplechannel @ rated speed (2133MHz) and timings? Thanks for your help Link to comment Share on other sites More sharing options...
trackrat Posted October 23, 2010 Share Posted October 23, 2010 No. Each KIT has specific frequency and latency timings. You will not be able to run multiple kits at the higher frequencies or the lower latencies. In fact mixing of kits is not recommended at all and may not function. You need to know that the frequency that the memory will run at is only one consideration in your PC. The CPU/memory controller must also be willing to run at the speed the Corsair memory has been tested and approved to run at. See my signature. Use the Memmory Finder link to the left to find the appropriate Corsair RAM for your CPU/Mobo in 12 GB. if that is the quantity you desire and purchase one tested approved KIT.

ThEButcheR Posted October 24, 2010 Author Share Posted October 24, 2010 Hi trackrat, I think you didn't get me right. I don't want to mix the Triplechannel and the Dualchannel Kit. I want to use 3 Dualchannel Kit's as 2 Triplechannel Kits. 3*2 DIMM's=6= 3 DIMM Triplechannel + 3 DIMM Triplechannel (3 Dualchannel Kit's) 2*3 DIMM's=6= 3 DIMM Triplechannel + 3 DIMM Triplechannel (2 Dualchannel Kit's) Do you get my idea? But now my question is: Will 3 Dualchannel DIMM's in Triplechannel perform at the same Speed like they would in Dualchannel? Or will running them in Triplechannel lower the Speed/MHz?

Wired Posted October 24, 2010 Share Posted October 24, 2010 The answer is still no. Is it theoretically possible? Yes. Are they tested, guaranteed, or warrantied in any config aside from how they're packaged? No. Also, don't forget 2133 MHz is a hell of an OC on any memory controller. Maxing out the work the memory controller only increases the strain on it, regardless of speed. Best to get ONE kit that will meet all of your requirements, and if it doesn't, attempt to OC one that's the same size and of similar speed. Just don't assume that any and all memory kits / CPUs are overclockable. Link to comment Share on other sites More sharing options...

I didn't misunderstand. The answer is "NO" unfortunately, for all the reasons in my post above. Link to comment Share on other sites More sharing options...
ThEButcheR Posted October 25, 2010 Author Share Posted October 25, 2010 Yes, I know that the best is buying one Kit which has everything I need. But the problem is, that the fastest Triplechannel Kit on Newegg is "only" 2GHz, and according to some reviews, this Kit is working at it's maximum, so you can't expect overclocking more than 50MHz, and 2133MHz would be nice to have, since I'm doing some really RAM intense work, which extremly benefits from high RAM speeds. But it looks like, the 2GHz Triplechannel Kit is the fastest I can get, so I'll try that. Link to comment Share on other sites More sharing options...
trackrat Posted October 25, 2010 Share Posted October 25, 2010 The likelihood of three kits working together at 2000 MHz. is about zero but you can give it a try if it makes you happy. The reason why you don't see any 12 GB. triple channel memory kits @ 2000 MHz. is because it's extremely difficult to run six DIMMS @ 2000 MHz. The latencies will also need to be slower as the ratings are for 3 DIMMs not six. FWIW, I doubt you'd see any real performance diff between 2000 MHz. and 2133 MHz. even if you could run the RAM at those speeds. Link to comment Share on other sites More sharing options...
Wired Posted October 25, 2010 Share Posted October 25, 2010 Better question to ask: Do you WANT or NEED 12 GB @ 2 GHz+? Why? Link to comment Share on other sites More sharing options...
ThEButcheR Posted October 25, 2010 Author Share Posted October 25, 2010 Since I'm building a rig based on the EVGA SR-2, I need at least 6 DIMM's, 3 for each CPU :P. I know that running 6 DIMM's on one memory controller is lowering the possible speed alot (my i7 920 wasn't capable of more than ~1400MHz when using 6 DIMM's, but I'll run 3 DIMM's per memory controller, so that shouldn't be a problem. I'm running some custom science programs for university, and they do benefit from high RAM speeds. Link to comment Share on other sites More sharing options...
Wired Posted October 25, 2010 Share Posted October 25, 2010 Then getting 2 kits, one per CPU, MAY work. Honestly don't know much about the architecture about MP rigs. If the memory controllers and the pathways are truly independent of each other then it may work just fine. Link to comment Share on other sites More sharing options...
ThEButcheR Posted October 25, 2010 Author Share Posted October 25, 2010 Both memory controllers etc. work completely independent of each other. So it might be possible, that the 2133MHz Dualchannel Kit will also run at that speed in Triplechannel? I know that nobody can guarantee that, but do you think there's a chance?

Wired Posted October 25, 2010 Share Posted October 25, 2010 Possible sure, but slim. If you're looking for REAL speed: https://shop.corsair.com/store/default.aspx?category_id=766409 Note that they're only guaranteed at those speeds running one stick at a time and are tested on P55 systems, but hey, if you're gonna go for broke :) Link to comment Share on other sites More sharing options...
ThEButcheR Posted October 26, 2010 Author Share Posted October 26, 2010 :P Yes, this Kit was the reason why I asked if running a Dualchannel Kit in Triplechannel would influence the Speed, because I've read that the Performance of that Kit in Dualchannel is lower than in Singlechannel. Hey Wired, thanks for all your friendly answers! Link to comment Share on other sites More sharing options...
forgetfool Posted November 27, 2010 Share Posted November 27, 2010 There's a crazy expensive kit of 12x4gb available, as well as a no longer available 12x2gb kit that was available. I believe both were successfully overclocked with a nitrogen cooled O.C'ed cpu for some bench marking insanity, but like was said...for what could you want all of that impossible to address memory? If you're interested in running scientific comps or heavy engineering go with 12 to 24 gb of the Dominator RAM (still quite fast and stable) and then add a $2,300 Tesla card. I'm finishing an SR-2 rig that's mainly for 3D work and some video editing and that's exactly what brought me here. There's a very limited amount of really, really crazy fast select modules out there, and they're really, really stupid expensive. It's actually cheaper, more stable, more energy efficient and longer lived to go the Dominator / Tesla route. Work like yours in particular will also be better served speed wise as well. I'm not sure what purpose three to four thousand dollars worth of mother board specific RAM would serve. At least with the GPU supercomputing card it's portable and can be reused in a different system. I can't imagine what type of science comps would be worth trying to run at that kind of wild speed with any real precision. Leave the RAM unfettered and the Tesla GPU cores to do the heavy computational lifting. With all of the threads (assuming you're running six core CPU's) you'll have available you could probably still run other work utilizing the RAM while the Tesla chewed and swallowed in the back ground. I am assuming a great deal here about your work but that's essentially the way the Tesla guy at Nvidia explained it to me. I could design in Maya, render animations on the Tesla and still have enough CPU, normal graphics card headroom and RAM (assuming I had 12-24 gb of good stuff to start with) for dynamic editing while the program was still rendering. That's a huge amount of computing. I'm not even sure that I want to be able to work that fast. :roll: Anyway, check'em out. The Dominator is the best valued performance RAM that I've found and that's without any kind of insane uber overclock. When you start dealing with race horses in really thin air things tend to get shaky pretty fast. Aside from that there really aren't many choices in the rarefied air of hand tested modules in the first place, and of them Corsair's definitely the best for the money. Sorry if that sounded a little condescending :o:...wifee doesn't let me out much. :sigh!: Link to comment Share on other sites More sharing options...
