Anyone running ddr3 16000 at stock speed in Z77X-UD3H pls?

it will run at 1600mhz,just look in bios and either set to xmp if the memory supports it or set the ram freq to 1600mhz
 
im pretty sure,if the mb lets you set to 1600mhz then you should run it at that,theres not much difference from z68/z77

i cant see why the motherboard supports sandybridge cpu's yet wont let you run memory at 1600mhz? thats just silly to me,ill ask on gigabyte forum to make sure but im pretty certain youll be fine

from that link "Each module kit supports Intel® XMP (Extreme Memory Profiles). " so that memory does support xmp

EDIT: i know someone right now whos running 1600mhz ram with a sb chip on a z77 ud5h

Pretty sure it means running 1600mhz ram on a sandybridge is overclocking it, as in it does not officially support it.

First, the new HD 4000 GPU contains 16 execution units, versus the 12 built into Sandy Bridge. Second, Ivy Bridge supports DDR3-1600 memory, as opposed to the Sandy Bridge memory controller, which officially supports only DDR3-1333.

I've never known a sandybridge cpu to not be able to run 1600mhz ram though!!

Plenty of 1600Mhz RAM in there, it'll run fine. It may not be the default speed with a SB CPU in there, but you should be able to get it running at 1600MHz [as loads of people have with Z68 and Z77 already]

I think the only way to make SB on ud3h Z77 run 1600mhz ram is if you OC it... Anyone actually have success running it at that speed on those settings? ta
 
it will work,another user who knows his stuff said so,you just adjust the speed in the bios like you would with any other ram
 
In the M.I.T. section of the BIOS set the XMP Profile to enabled and then set the DRAM voltage manually.

I suggest you start at 1.55V as this will work most of the time.

If it needs a little more then increase it a bit but try not go over 1.60V.

If it works at 1.55V you can just leave it or try and reduce it a bit if you wish.
 
I have the HyperX stuff on a Maximus V Gene Z77.

I started with them as Surveyor said, at 1.6V, but then had a play around with them and managed to reduce the voltage and tighten up the timings a bit.

Mine could run at the stock 1600Mhz 9-9-9-27 2T timings at 1.5V with no problem.

Currently, I have it at 1600Mhz 8-9-9-24 1T also at 1.5V with no problem. I couldn't manage to get 1866Mhz out of them even at 1.6V with slackened timings.

Hope this helps.
