Can you run 2400mhz ram in Crosshair V Formula-Z stock? - Page 2

post #11 of 25
The Crosshair V or -Z can run RAM right up to 2600MHz..... that's if you can play it right though, timings, the golden CPU memory controller etc etc..... But most FX 81** 83** CPU can run 2400MHz all day long.

Hey, I liked your idea and I am basicly seting up the same system as you, and I've been wondering over how it will work and what tweakings I might had to do. So My system specs are An AMD FX-8350, Corsair Dominator Platinum 4x*4GB (standard clocked to 2133) and a Crosshair V Formula-Z Motherboard, I also have watercooled my CPU with a H100,

Aditionaly my case and PSU and screen card won't come before next week or so.. So I took my time Reading about the stuff, like in the manual for the MB it says it tacles the normal clockspeeds on RAM and (2133 O.C.) and (2400 O.C.) I trust you know what you're doing when you answer me. Thank you, and I love that it's not only me that has thought of this kinda build ^_^

P.S. This is my first build at home, even though I am going to school to teach about copmuters and electronics I still consier myself an newbeginer, I know all the components and their purposes as well as how circuts works, and I do know safety behind this too. I have been reading on this stuf at home as well for good over a year now, so I thought to my self why not do something about it now?

actually it doesnt change the fsb it changes the dram multiplier in bios. so you dont need to do any voltage changes.
mine runes 2133 allday long with stock voltages on the cvf I forget off-hand what the setting is called but its one of the options
in the extreme tweaker menu

How much RAM are you going to load up? Depending on the setup and how strong your CPU's IMC is it may be impossible to get 2400MHz. Only setups I know that can get 2400MHz+ with all banks loaded up (4x8GB) is Ivy Bridge.

Not to mention most of, if not all Corsair Dominator Platinums are Intel XMP 1.3 profile only. So for AM3+ anything above 1866MHz would be overclocking.

I said that I am going to load it up with 4x4GB (16GB) in a clock of 2133 (and when I think of it mabey even 2400?) I can pull off a Water loop on the system though And If I do this I will also Put a waterblock on the RAM. But I will first need to know What Radiators and what Pumps what tubes and blocks I need. And this is hard to decide since I haven't got the case sent yet.

I am new to overclocking and I hope it is ok to bring this post back to life. I have a problem overclocking my crosshair.

I bought a motherboard which could handle ram speeds up to 2400Mhz oc and upped my ram to run at 2400mhz standard. I heard AM3+ can't go above 1833 without oc, but when I try anying above 1833 it does not boot. blank black screen and I am forced to do a cmos reset.
if anyone has had this problem and know what I can to to fix it and/or do something next time to run a 8-core AMD (hopefully 5Ghz next time) with 32 GB for 2400 or even 2600Mhz let me know.

ASUS Crosshair V Formula-Z AM3+ AMD 990FX - UEFI BIOS
AMD AM3+ 4.0 Ghz 8-Core
Kingston HyperX Beast 16GB (2 x 8GB) 2400Mhz -> voltage at 1.65v
Sapphire Radeon HD 7870 GHZ 2 GB 256 -bit
750 watt power supply

Windows 8 if it maters.

If your wondering why I would want to do this, as it seems to be the popular response: it is to use what I have paid money for if and when I need it. right now I am happy playing game on it with no problem. but I would like to know what setting to change to get this to run at it's full potential when graphics and ram demanding needs come up. (rendering HD uncompressed video, rendering 3D models, or even as crazy as it might sound: rendering HD graphics in real time for live gameplay)

Thank you for you time.

there is a setting in the bios let me find the name
its called memory frequency on the extreme tweaker tab
if you go to that tab itll be one of the first few options and it'll
give you the option for 2400 or several others lower then 2400
theoretically it runs the memory at 2400 even though the cpu only
accepts it at 1866 basically it lets you saturate the memory bus
at least thats how i see it. since the cpu cant accept data any faster then
1866 due to its imc.

X.M.P. works and is an available option in the bios on most mid-high end AMD motherboards.

You would've been better off spending the money on a moderate 2 x 8gb kit of memory instead of a really high priced 2 x 4gb kit. But good luck regardless.38.gif
