The computer doesnt like to boot with 2 ram sticks.

Hello. Few days back I bought 2x 4gb memory sticks, the link to it will be posted below.

The first time i started using them, i went to my bios, gave the dram 1,65V and enabled the X.M.P. After that I started to test the ram on the software, for which i bought the ram for and noticed that the screen is glitching and the application is crashing when the ram hits at around 6 - 7 gb used. After the application crashed, I started simply browsing the internet, maybe thought it just needs time or whatever... tho my display driver started crashing over and over again untill i got a blue screen. I restarted the computer and the display driver started crashing again, tho it didnt bluescreen untill i turned on my second monitor. It was only then, when I finally did some research to find out if i even can run the ram, and it turned out i could, but not at its maximum potential. The ram was supposed to be 1600 mhz, but my CPU, since its sandybridge, could only handle 1333 mhz so i went to bios set the voltage to default and disabled the X.M.P. Also i opened the case and noticed that the second ram was like ~1-2mm out of position, so i straightened that out, booted up the computer and everything was running perfectly.

The next day i tried to boot the computer, it just wouldnt boot. It would power on, show the "thinking" light for a split second and turn off, then by itself turn back on and repeat. It didnt even get to peeps, its just cyclin on and off. I was sure that nothing could have broke, so I took out the ram sticks and switched their sides, the computer booted up and ran perfectly for the day.

So the next day the same thing happens, but this time i dont switch the ram sticks, i just take them out and put them back in where they were, and the computer boots and runs perfectly again.

Today that didnt work anymore, so i took out the second stick entirely and put it back in the case, which came with it when i bought it and the computer boots and runs perfectly again, tho i dont have the extra 4gb ram anymore.

I was wondering, since you guys are very experienced in these kind of stuff, could it be that im not directing enough power to the ram sticks, for it to boot correctly? I have a 750w psu and im not even using it at max potential. I estimated that my system would need only around ~400-500w psu. Even if the PSU is being used at its full capacity, can i somehow redirect some power from the graphics card, since the fans are getting very old and fail to cool the graphics card.

Here are the specs.
Operating system / Windows 7 64bit
Motherboard model / H61MU-E35 (MS-7680)
Motherboard BIOS version / A.30
Graphics card model / NVIDIA GeForce GTX 550 Ti factory overclocked
Processor / Intel Core i7 - 2600 8k (it may be 2600k, i dont really know. When i bought it, the papers said 2600k, cpu-z says 2600)
Ram / Some hyperx genesis 2x 4gb @ 1600mhz 1.65V - http://www.kingston.com/datasheets/khx1600c9d3k2_8gx.pdf

If theres anything else I should add, let me know.
Thanks in advance.

P.S. I have tested the sticks and every other component, they all work unless the both sticks are placed together.

I'm thinking that it's just a case of getting the settings correct in the BIOS. Your memory should work fine at 1600Mhz as long as the voltage is set correctly. Are you installing the two DIMMS in the correct slots? There is usually an order of preference given by the motherboard manual and they should always be in the same colour slot (assuming you have different colours). XMP Profile should really auto set the frequency to 1600Mhz and also set the voltage but it is advised to set the memory voltage manually. Ensure that there is a nice "click" at either end when you firmly push down on both sides of the DIMM. Your PSU should be way more than adequate for your system so there is no problem there.

There are only 2 slots on this motherboard, so the sticks are placed correctly. Also, when i used xmp, it set the 1600mhz in bios, but after the bios were loaded, it auto set it back to 1333, since my cpu cant handle more, as its written already in the first post.
Also i have tried to set voltage manualy, it did not work.

Mobo only shows support through 1333 for Sandy Bridge CPUs (which you have), might check for a BIOS update, which might help, the 2600 (or 2600K) should be strong enough to carry 1600, but the BIOS may be playing in from when they updated the micro-code to enable the use of Ivy Bridge CPUs (where they added 1600 DRAM)

I had checked the bios update changelogs before making this thread, they didnt say anything about ram so Id prefer to not mess with bios, if its not necessary.

They seldom do, most BIOS updates consist of a large number of items being updated, they normally only list 1 or 2 things, but more often than not there will be a large number of individual updates that revolve around the setting up of DRAM, since new sticks are constantly coming out and the testing they do initially is limited to sets they have immediately available, which is why the QVLs for DRAM are so small in comparison to the overall sets available

Updating bios didnt help, any other ideas?

9:9:9:27 and cr was 1. But could timings really keep the computer from booting up? Do they even get "set" at the first second the computer starts?
Also for voltage, its set to auto, because i can only pick 1,35, auto and 1,65, so i assume auto means 1,5, since 1333 shouldnt be using more.

Yes, when the computer initially goes into POST it checks the hardware. Try booting with a single stick and manually set freq 1600, timings to 11-11-11-30, CR to 2T and DRAM voltage to 1.65, save, exit shutdown and then add the second stick and try

A little question before I do that. How does the voltage actually go to the ram. Does the 1.65 means like it caps at 1.65 volts or the ram is constantly getting pumped with 1.65 volts? If its constantly getting... bla, bla bla, and it would turn out to be too much, could it overheat/break the ram? Because I wont be able to use 1600mhz, I can only use 1333 mhz.

P.S. Why are there such options as "AUTO" if we cant use them anyway?

But what about 1333mhz? As I said, i wont be using 1600. Can i just leave the voltage at 1.5 if im using 1333?

Well, i set everything to auto and it looks like the computer is working, atleast first time when i booted it after new settings it was working perfectly all day, but today i bluescreened out one time, its working fine again now tho.

Also, before you lock this thread, When a computer is turned off, are the video card, mobo and everything else supposed to still remain warm till morning? Arent the power supposed to be turned off?

Trough windows and also tried the button on the case.

Had to edit this to tell you that the booting problem is back. Looks like it didnt even get fixed, just some lucky boots... Any other ideas?
