How to use XMP on Windows?

Hi. My PC consists of a ASUS P8Z68-V PRO motherboard (BIOS 0501), Intel Core i7 2600K CPU, Gigabyte nVidia GeForce GTX 560 Ti GPU and 4 DDR3 memories G.Skill F3-12800CL7-4GBSR. I'm not using overclock and for the moment I won't use it because I'm using the Intel stock cooler wich is crap, haha. In the BIOS everything is on the default settings except the boot priorities and some minors things i disabled like the Marvell SATA and JMicron eSATA wich I don't use. The problem comes when i activate the XMP (Extreme Memory Profile) of the DDR3 modules, Windows 7 won't boot. It shows a blue screen for a seconds and reboots and do the same. I'm using Windows 7 Ultimate 64 bits Edition with SP1 and all the drivers and updates installed. I'm not sure of what I'm doing wrong. Can anyone give me a hand with this? Thanks.

manually set the memory timings and voltage to whats written on the memory modules and see what happens
are you using 4 x 2gb modules or 4 x 4gb modules?

if i use 6 x 2gb on my ex58-ud5 i cant run xmp but if i only use 3 x 2gb it works fine

Windows vs XMP is not the problem as windows does not care if rhe Ram is DDR3-13330 CL9 or DDR3-1600 CL7, Unless you acidently change another parameter such as HDD sata/ahci/ide mode.

When you selected XMP and selected profile 1 then rebooted. Did you go back int the bios to verify that the CL values were set correct and that the Dimm Voltage was correct. NOTE: did not see your specific RAM. I Have the Ripjaw DDR3-1600 CL7 @ 1.60 volts. For the SB processors, Intel spec sheet list 1.575 V max for Dimm voltage. Althogh may use the 1.65 V. @ mcnumpty23 - For 2 Sets of Ram: On some MB, X58/P55 and older you need to jack up FSB Voltage by 0.05 to 0.10 V and sometimes also increas Dimm voltage by a small amount. If this is 1.65 Volt Ram on a SB System, DO NOT recommend Overvolting it as it is already above intel spec

What you need to do is download the Memtest86+ ISO and create a bootable CD. Use this to verify that you memory is working and stablle BEFORE loading the operating system.

Not sure if you have 4 sticks (4 x 2) for 8gigs, or Just 2 sticks for 4 Gigs of Ram.
So it is possible that you have either a bad stick or a bad socket.

If Just two sticks and you get errors (Need to run a Min of 2 to 4 Hrs) then try just one stick then try the other stick, if neither works then try in different slots.

If 4 sticks. Make sure you keep in matched pairs. Basically the same as above. Remove one pair, check and swap and recheck. If you can nnarrow it down to one pair then do as outlined for 2 sticks.

Thanks for your answers. I have 2 packages of "G.Skill Sniper F3-12800CL7D-8GBSR" (http://www.gskill.com/products.php?index=386) so there are 4 sticks of 4 GB in my mother now. This is the complete information of the memory in AIDA64:

So to get to those timings I need to use XMP. In the G.Skill product information website my mother (ASUS P8Z68-V PRO) is listed as "Qualified Motherboards List" but in the ASUS website the memory is not listed as "Qualified Vendor List".

I updated to the new BIOS of my motherboard, the version 0606. But the problem is still there. Here are all the options in the BIOS selected to run X.M.P and Windows 7 don't boot:









































All the options are the default of the BIOS, except the ones in the Boot Panel, and that I disabled the Marvell SATA and the JMicron eSATA. In the Ai Tweaker Menu i just change the first option to X.M.P and others options changed automatically I didn't touch anything more. Someone know what I'm doing wrong. Thanks!

you have memory timings in your post of

your bios shot is showing 7-8-7 @ 1600 @1.6v

^ His memory is DDR3-1600 CL7 so That requires using XPM profile 1 which is what he has selected in bios and 7,8,7,7 @ 1.60 is correct.

(2) As I indicated, the first step is to Verify the Ram. Remove one set, leaving one set in the preferred slots and run Memtest86 from a bootable drive. If it passes then install the 2nd set and retest.

If all four pass memtest 86 (min run time 4 Hours), then I would try redoing my win 7 Installation. NOTE do a Custom install and on page where it ask where to install - DELETE all Partitions First. Then I would partition the drive with a 200->400 Gig partition for the operating system plus programs. Leave the remainder of the Drive UNPARTITIONed (can do after everyting is sorted out). Select the 200->400 Gig partition to install wind to.

Thanks for your help. I will try now the mem test.

No Luck. I've run the last version of Memtest86+ (4.20) from a pendrive. I put all the default settings in the BIOS. And test each SPD putting alone in the DIMM_A2 (as is the recommended slot for 1 SPD), the 4 SPD passed all tests. It took about 20 minutes per SPD. Then I've putted the four SPD and ran again the Memtest, it took about 1 hour and 15 minutes and passed all the tests. The funny thing is that now I've putted 2 SPD (2 x 4 GB) in the slots DIMM_A2 and DIMM_B2, activate X.M.P and Windows 7 boot fine and as I can see in CPU-Z the memory is running at the 7-8-7-24 latencies. The problem comes when I add 2 more SPD in the slots DIMM_A1 and DIMM_B1, and Windows won't boot. It stops booting almost when the four points of Windows are joining and show the blue screens for a seconds and the computer reboots or turn off.
I think the problem is the motherboard. I will contact to ASUS to inform about this and maybe they can give me a solution. Thanks for your help

Well I wrote to ASUS and they don't wanna give me any solution because they claim that if the memory is not in their QVL list, they don't have any responsibility. The funny thing is that they never explain that their motherboard is ONLY compatible with their list, wich is a optional download, instead they say any DDR3 with the X speed and X voltage are compatible. Further the G.Skill product info about my memories put as QVL this motherboard. So I feel cheated. Next time I will buy Gigabyte, I've lost all respect for ASUS.
