Extreme Memory Profile enabling (X.M.P.)

raise volts?

Well, I cannot raise volts as it is automatically set to 1.65 and freq is set to 2000 all these being set by automatic setting (gray). Normally it should work moreover if is the only setting from default?

I Recommend manually setting the ram voltage automatically vice auto. Using cpu-z, auto did not give my ram the recommended voltage.

Hmm, I did a load optimized defaults, enabled XMP, changed from spd to quick and checked all the settings,they showed 9-9-9-9-24 and voltage 1.65, tried to boot, at load OS pressed Del and entered memory check but it froze there. I did the same with default settings, memory check OK. Now I see on the description of the board that it supports DDR3 2200/1333/1066/800MHz, I assumed that it support 2000 also if 2200 is supported. Could it be the issue?

Well, no, I did it after a fresh "load optimized defaults" so all settings are to their defaults, this was the only thing changed. I have only 21 max multiplier anyway so no 182*22 :-(. I saw some guys recommending to go with an uneven multiplier 19, 21 and so on. There is any advantage to go 21*190 instead of 19*210, or vice-versa?

The main issue is that the XMP does not work with default settings when everything is stock, I am not talking about OC-ing, I just wanted to see the impact of 2000 bandwidth against 1600 which is normally set. I found this link
http://en.allexperts.com/q/PC-hardwa...erformance.htm and this explanation

made me think that indeed nowhere on my board is specified 2000 just 2200, and till now it is the only reason I could find to explain the fact that it is not working, even on stock speed.

If you look at the MB specs in the link, you will see that it is more or less the same situation:

And that guy made the same stupid assumption as me believing that 1800 memory as it is in between 1600 and 2000, is ok.

Have you tried entering the settings in manually? This generally gives better results than just selecting "XMP" in the BIOS and rebooting.

Yes :-(, same behavior.

Please ignore my signature, it is doing this at stock speed, all settings are fresh default. So they should be on auto, or disabled as I run it on default 2.66 GHz

Well, I've managed to get a pair of XMP 1600 ram sticks and my suspicions became true. I have to open my eyes before I buy something next time :-(. The XMP enabled @1600 went smooth no issue and I managed to get 1600 OC on RAM. Indeed error10 has been right I have no improvement in performance opposed when I have my 2000 XMP(disabled) ram inside OC'd at 1600 with [email protected] I think we can close the thread. Thanks to all of you for our time and help.

I had the same problem, i did 2 : 1 on my uncore and it solved the problem.

1 : 1 for uncore doesnt seem to cut in xmp mode.

Hi

What do you thing about below diet supplement? I'm going to buy something good for muscle growth. Please give me a piece of advice.
