Ram is being really weird !

So I bought 1866 mhz for my mb that supports it and it it runs at 1439 mhz and won't lemme go to 1866 , what do I do ?

Have you identified all of the critical elements for the timing of the RAM and set them manually?

While most motherboards are validated for up to a certain speed of RAM, that is never a guarantee you can run at that speed. It's mostly a marketing point.

The most crucial part of the equation is the memory controller that is actually interfacing with the RAM, and that is on the processor.

So, what processor are you running, and what is the board? We can't offer help that is very detailed if you don't offer up a few more specifics about what you're working with.

On the Intel side of things, their newest controller, the one in Haswell, is really only spec'd on paper to run up to 1600 MHz, and AMD's controller in their FX line is only rated up to 1866 MHz. The catch with this is they are only rated for two modules on the AMD platform and four on the Intel side of things. So, trying to run with four modules at 1866 is just plain unsupported, even if you can find timings that will allow it.

Not trying to be negative, but feel you should have the best picture of what you're working with so you can plan accordingly.

What mobo and CPU, also what model 3 for the DRAM? - it doesn't matter WHAT the mobo does /can do, you need a CPU that can carry the sticks

I have the amd 8350
Vishera ! And the asus sabertooth r2.0 990fx mb and ddr3 ram!

No model for the DRAM so I can't help on manual setup, so, make sure you have the latest BIOS, then install the sticks securely in slots 1-3 or 2-4, go into the BIOS and on the advanced or tweaker page look for EOCP or DOCP (AMD s overclocking profiles or XMP and enable whichever and set to 1866

I have corsair vengeance dram!

Tradesman1 · Aug 10, 2013

Sorry, this is why I always try to ask specifically for the model #.....do you have any idea how many different sets of Vengeance there are, even in 1866 alone, think they have sets with CL ranging from like 9-11, voltage from 1.5 - 1.65, etc Specific sets often have specific characteristics, also often have/use different advanced timings

And while we're on the subject, is it a 2 module kit or a 4 module kit?

Mrgigabyte123 · Aug 10, 2013

Here's the model I think , I feel the one I got was 20 bucks cheaper but here's what I think it is ! http://www.amazon.com/gp/aw/d/B007QY87MG/ref=ox_sc_act_image_1?ie=UTF8&m=ATVPDKIKX0DER

Ok initially manually set it to freq 1866, base timings 10-11-10-30, 2N or 2T and DRAM voltage to 1.55 also raise the CPU/NB voltage + 0.15

Mrgigabyte123 · Aug 10, 2013

+.15 what ? How do I now what to add when u dont know whats its running at ?

Mrgigabyte123 · Aug 10, 2013

And it only goes as high as 1729 mhz for some reason?

Tradesman1 · Aug 10, 2013

Try it at 1.25
