No option to load XMP in Asrock mobo

[ratsa]

I just put together a system with an Asrock Z77 Extreme4.

The option to "load XMP setting" is totally missing from my BIOS.

I have upgraded to the latest firmware. I did not notice whether this problem existed before I upgraded.

Is this likely to be a problem with the mobo or the RAM sticks?

More information.

I have installed 4 of these Team Vulcan memory sticks, which are supposed to support XMP V1.3:

In the Asrock Z77 Extreme4 manual it says that there is an option called "load XMP setting" in the OC page.

In fact, there is no such "load XMP setting".

The CPU is i7-2600K. I have not changed any OC settings. Everything is running at stock/default settings.

Any thoughts?

Set the speed manually.

You have a user manual... use it. In fact, look in there and check out the "supported memory" because maybe what you bought isn't officially supported.

The manual says that you can use XMP, which is why I am asking this question.

Without XMP, how do I know what the speeds are?

On the page you linked to for the RAM.

CL-tRCD-tRP-tRAS 9-9-9-24
Working voltage 1.5V
Data transfer bandwidth 12,800MB/Sec (PC3 12800)

That last one might be a little confusing, but it means 1600mhz.

Everything else can probably just stay on Auto.

Otherwise if you really want XMP you will have to contact Asrock and/or Teamgroup support.

If it's that simple, what is the advantage of XMP? The mobo automatically selected settings that work. For some reason, it defaulted to 1.585 volts. I reduced it to 1.5 and ran memtest for 10 hours with no errors.

"eXtreme Memory Profile"

Often the motherboard will pick the first one up by default, but not always. Sometimes a set of RAM might have 2 or 3 XMPs, with the 2nd and 3rd having more aggressive speeds, timings and/or voltages. The RAM I bought specifically said that the most extreme profile was not guaranteed to work, and sure enough it was like 1600mhz CL7 1.8V (Way too high).
