Corsair Dominator Platinum 1866Mhz - 2400Mhz Compatibility with X79

[Olaipai]

Hello!

I've got the Asus Rampage IV Formula/BF3 and I am curious about something considering RAM.

Does the motherboard support 2400Mhz, 2133Mhz or 1866Mhz? I am considering getting Corsair Dominator Platinum 8GB 1866Mhz and overclocking it to 2400Mhz or 2133Mhz.. But I am not sure if this will work with the heat and the 1866Mhz RAM might be limited? I know the RAM is supposed to be extremely overclocking friendly and look great (They look seriously good

), but I am not 100% conviced. Any one knows something or have the same motherboard and tried this high end RAM or tried other modules with great memory frequencies? I am a speed freak, just to be clear..

Specs:

MOBO: Asus Rampage IV Formula/BF3

CPU: Intel i7-3930k Stock speed.

RAM: Corsair Vengeance Red 8Gb 1866 Mhz.

PSU: Corsair AX 850W.

GFX: Asus Geforce GTX 670 DCUII TOP.

Case: Corsair 800D

HDD: WD 500GB Black (Main storage)

SSD: Intel 520 120Gb (Boot and games storage)

Cooling: Custom Watercooled cpu

Interior light: Red and red water loop.

Accessories: Corsair link and light kit, Corsair AF fans 120 and 140mm and Corsair SP 140/120mm fans on radiators, NAS with 2x 2Tb WD Black HDD's and Lacie 2big 4TB Quadra external storage.

Info: Everything is going to be overclocked big time when the right memory modules hit the ram slots on the mobo.

Thanks for all answers!

The memory controller on sb-e might not do 2400 mhz even though motherboard supports it (asus website says 2400mhz), and to be honest i dont think that you will notice the diffrence between 1866 and 2400mhz. Although if you want i think most sb-e cpus can do 2133.

 

[Olaipai]

Oh, so if I get 1600mhz Platinum, it will be an easy OC to 1866 or 2133 or 2400Mhz?

 

[giannakos23]

no dude !! 1600mhz is going to be difficult to oc to 2400mhz ...and apart from that the newest revision of sb-e cpus will be able to keep stable 2400mhz ram ...i'm not sure though ...i'll search and i'm going to post back !!

There's overclocking well...

And overclocking by 50%...

I'd say unless they accidentally send you 2400mhz with a 1600mhz sticker on, there's no way you'll get up that high - dont get your hopes up.

Besides there's no difference in anything but benchmarks with RAM over 1600mhz

yes you are right !!!

3930k wont do 2400 without tweaks and even then you need a EPIC chip

90% just wont do it.

2133 will still need to be set up manually and have some voltages fetled. You are playing with big boys toys now. If you want to leave everything on Auto youve bought the wrong stuff.

Buy the ram speed that you want, set it up. Leave it. You have a lot of learning to do before you can start talking about overclocking to silly levels.

You are just showing off your n000000b badge by even thinking it.

As TTL says, just get the speed you want:

As an owner of 2133MHz RAM, I can say with complete confidence that it was a waste of money. 1600MHz is what to get, until the higher speeds drop in price.

Very narrow minded, some programs thrive on bandwidth.

I don't think SB-E handles 2400MHz well. I tried a friends kit in my own system and couldn't get it stable at those speeds on my 3930K. I have 1866MHz in my own rig and that's stable, pushing it to 2133MHz works on my chip too but 2400MHz = no go.

I'm not really that fussed about it myself, 1866MHz in my rig and it screams. I ran it a bit lower when overclocking (whilst altering the BCLK) and I managed to get higher CPU scores in every benchmark I tried by running the CPU at 125 BCLK vs 100 with the RAM at about 1666MHz instead of 1866MHz.

As an example I got about a 6% performance boost in Cinebench just from raising the BCLK with almost the same CPU clock. (4.3GHz @ 100 BCLK vs 4.375GHz @ 125 BCLK) - It surprised me and I think it shows that perhaps Intel need to raise the QPI bandwidth soon for it to have such an impact.

Figured I would ask here and not start a new post.

How does the CPU memory controller handle 2133Mhz with 8 DIMMs?

I'm thinking of getting 2 x 16GB Corsair Dominator Platinum kits (@2133Mhz; obviously).

Either that, or the 32GB (4x8GB DIMMs) kit, but much like Tom with his Orca build it could come down to aesthetics.

 

[tinytomlogan]

You just need to up some of the supporting volts in bios. Each manufacturer calls them different things.

8x2133 will need a serious amount of tweaking though

Hey Tom, I am about to change my ram modules to the 8x4gb 1866 Dominator platinum. My processor sadly is still the C1 3960x (didn't have the chance to change it to C2).
Would the C1 work fine with the 1866? (I was using vengeance LP 1600 all this time).
Last time I tried using the 1866 gave a lot of weird compatibility issues on an R4E back in January, which I didn't see with 2133 and 1600 speed rams. Thanks

There is no real difference between C1 and C2.

As with all ram over 1333 you have to manually set it.

Hey Tom, thanks for the reply. I just received my 8x4 dominator platinum. Gonna try it out. Thanks again.

Is there anything wrong with the Corsair Dominator Platinum 4x8gb (32GB ) 2133MHz Kit?

Can't see it selling anywhere here in Australia, looks out of stock in most places in the world, and can't see any reviews on the net...

 

[airdeano]

nothing wrong with the 2133 plats.. as Tom was aluding to, its only a few
x79 chips memory controller can handle that speed. as an enthusiast, you
might be able to tweak and clock to make 'em work, but don't be dissapointed
if they can run that speed as a drop in. remember these are hand binned and
prolly a lil hard to obtain..

[Blackwidow]

It's not the 2133 I'm worried about, I intend to tweak them to get the best performance I can. I was just interested into why no one seems to be getting the 4x8gb kits, they get 4x4gb or 8x4gb.

The 4x8gb kit is cheaper than two 4x4gb kits, and I would assume having only 4 DIMMs would be less strain on the memory controller and thus potentially have a higher overclock frequency.

Am I missing something?

 

[airdeano]

different sized memory chip.. more data strings and size than the 4GB modules.
same size boards bigger chips, and to "match" that many for quaility control can
be a bugger..
and you find the price might increase upon availbility..
