Which X79 Motherboards support 2600mhz Ram??

post #1 of 6
Thread Starter 
Other than the X79 ROG (Dont want to spend $500) which motherboards support 2600mhz Ram?

I preferably want a motherboard to support SLI x16 each lane and up to 2600mhz RAM using a 4820K CPU. Is this possible??

I tried looking at a few spec sheets on the corresponding manufacture site but most only get to 2133 or 2400, are they able to reach 2600 even if its not listed??....

http://www.newegg.com/Product/Product.aspx?Item=N82E16813130681

I really like the above board, but it only hits 2400mhz.

I'm currently on 1333mhz ram... so its definitely time for an upgrade as i game with SLI 670s/4gb and for music composition.

Thanks for all the help! thumb.gifthumb.gif

Stated memory speeds supported doesn't always mean much.

Coming from numerous reviews and my own personal experiences, ASUS' LGA-2011 boards tend to handle memory the best. The RIVE and P9X79 WS in particular have proven to be exceptional memory overclockers. It's likely that the new Rampage Black will follow this trend.

Anyway, when looking at these speeds, CPU is going be at least as important as board. Many CPUs simply aren't going to handle 2600MT/s memory.

I never owned an enthusiast chip but do plan to in the future. You should be able to run 2600mhz since its ivy-E. It natively supports 1600mhz ram. Wiki mentions it can do up to 2800mhz in 200mhz increments.

For example, my motherboard doesn't say anything about running beyond 2400mhz ram and yet it has the option to do 2666 2800 and 2866 in the bios so it should for ivy-E chips. Just make sure the chip can handle it.

So is it safe to say, i wont know until i pick a motherboard and try it myself via the bios??
Obviously picking a motherboard with already higher speeds supported.

ALSO if the ram supported is lower than 2600 will it downclock itself and still run like normal if it doesnt support those speeds??

Thanks again for the help guys!

Generally speaking, if you try a voltage/clock/timing combination that the RAM/Motherboard doesn't like, the system will simply fail to POST. It'll then go up and down a few times (Varies by manufacturer of motherboard) and eventually revert to stock settings. On some (poorly designed, in my opinion) motherboards, clearing the CMOS will be necessary to get back into BIOS.

By setting too high of a clockspeed, you really aren't hurting anything. Voltage is what can kill your RAM.

Please also understand that these are generalities, and your experience (including component failure) will vary wildly among manufacturers and situations.

EDIT: RAM will attempt to run at whatever you tell it to. For example: Samsung's low voltage kits are rated at 1600, but they'll hit 2133mhz consistently. So, the RAM doesn't "know" what speeds it's necessarily capable of. You can set RAM rated at 1333mhz to 3000mhz in your BIOS. I can guarantee you it won't boot, but there's nothing to stop you from setting it there as long as the board supports it.

Lastly, overclocking is never guaranteed. RAM is only rated to run at certain frequencies, timings, and voltages. The only case where you'd consider your RAM defective is if it will not run at the settings printed on the sticker attached to the sticks/box.

Definitely note worthy tips, thanks again.
I'm almost tempted to just buy 2400mhz ram to be on the safe side and not get 2666mhz unless its very well possible it will support it.
Also i will be doing a ASUS P9X79 motherboard, perhaps the pro or deluxe.
