the board works great with the 6 in but when i put the 12 gig in it locks up will not start at all now ive read a few bits on the forums about filling all the slots ....has anyone else experienced this and have they sorted it out as yet thanks
 
Hi mate ,

Need a little more info from you.

Is this all at stock settings. So are you overclocking your system at all. ?

What is the ram voltage ? Should be 1.65v - 1.7 depending on brand

You may have to adjust the QPI/VVT Voltage when all dimm slots are in use and it requires a fair bit more.

Have you removed the original 6GB and attempted booting with this new batch just to make sure they work correctly and stably.

Keep us informed

Did you buy both sets of memory at the same time?

I am running this board with 12Gb, my boot up with all sticks in place the first time at a lower speed setting 1066Mhz.
 
ok here is a bit more info installed windows on the 6 gig then put the 12 gig in it boots ok with 6 but hangs at windows with 12 gig,the memory is Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 (1600MHz) the voltage is set to 1.65 the timings 9 9 9 24 the qpi voltage is 1.175,and yes i bought them at the same time thanks for the help guys

What are your other settings, System Memory Multiple etc?

Have you disabled X.M.P?

Performance Enhance should be set to Standard

Are you O/C?
 
ok not overclocking the qpi/voltage is set to 1.175 ill go check the other settings you asked for ok xmp is disabled yes peformance was on turbo ive set to standard now
 
ok ive done what you said simon set the memory to 1066 and perfomance to standard and the xmp is disabled hey presto it boots with 12gig now....so all i have to work out now is to up the memory to what it should be....or is it ok to leave it like that thanks lol i have it running at 1333 now stable try the next setting must have been the performance set to turbo that was the problem so do i need to enable xmp or leave it disabled thanks

I would leave XMP disabled, as you can set the timings manually.

You may find that your CPU will not run at full 1600Mhz with 12GB, my does not like it.
 
yeah getting same results best is 1333 for 12 gig why does this happen lol had similar problem with other boards in the past and they have still not sorted it out yet
 
I have 12gb installed in my system. before I purchased some Gskill 2000 memory and it would not work at rated spec I thought it was board compatabilty problem, but when I purchased some Corsair GT 2000 memory when set to XMP the QPI voltage was 1.6v which they recommend. My point here is I still couldn't get a 4000ghz 2000mhz clockk with 6gb installed stable probably the old stepping i920 fault, but I tried the gskills at 1.6 and they booted.

I have since got Qpi volts down to 1.5V but am at 3.6Ghz at 1800mhz with all 12GB I was going to sell the other 6.

So if I were you try inputting 1.5v QPI and boot into memtest and see if they work ok then. i bet that is what the problem is.
 
Hi guys ,

I think its all down to the Intel Memory Controller. Especially when overclocking too. When using 6 sticks the QPI/VVT voltage needs to be increased a fair bit compared to 6GB. I am currently using 1.29v VVT on my board with 12GB. I have a maximum 3.7ghz overclock 176x21 however my memory is running @ 1410mhz 9-9-9-24 2T. As they are linked , any higher and they fail to boot.
I been trying for weeks now to achieve 4ghz with 12GB. I just cant seem to do it. 3.7ghz stable is the best i can do. Tested both memory sets and they are fine.
However , I had no problems running at stock 133 blck and 1600mhz 12GB. That booted fine and the IMC handled it well. Its when the OC comes into play.

So roachyuk start checking out the QPI/VVT Voltage , its probably got to be at a minimum of 1.26v for stock settings i would think. Maybe 1.24.

That is pretty unique Simon D. Congrats to you. I personally tried 4ghz , 1200mhz mem , 2400mhz uncore. Set the correct vvt ( well enough ) and everything. Did not even post for me.

What is the marketed memory specs your using. @ Them timings are pretty tight for 12GB.

ok tried changing settings in the qpi and all unstable will not boot....so do you think i should just run it at what it is now 1333 speed for the 12 gig
 
Hi m8 ,

That is your choice. I personally feel when at stock settings (133 blck) you should be able to achieve 1600mhz (or slightly below like 1592mhz) with 3200 Uncore 1.65v at the marketed timings and 1.26 - 1.30 vvt/qpi with 12GB.

I would run mem test on each 6GB and test it for 1600mhz. Then test the other lot. Your not over clocking so it should run in my opinion.

I am using 6 sticks of OCZ 3G1600LV6GK 8,8,8,24 @1600MHz.

I decided if I could not reach full speed on memory with a O/C, I would play with the timings I first went to 7,7,7,21 and that was stable 18hours + with prime 95.

Now testing at 6,6,6,21 27 hours + stopped, no problems so far, moving onto 6,6,6,19, 1T

I did find that if I was using IOH core set to 1.20v, I had problems in reaching 4Ghz. I found that once I dropped to 1.180v (now 1.160v) I was stable.

I can do 20x200 and 21x200 as well but I need over 1.4v on the Vcore to do so.

I found that 19x211 was better as I can run on lower Vcore.

Although im using a completely different board to you guys I thought id give it a go at putting some of these setting into my machine to see if it could get a 4ghz boot with full 12GB ram installed. NO GO ! ! !
I kept the dram low @ 1200 , 1244 and lower 1123. No post on any of them. I put 1.3v through the CPU , 1.32v on vvt/qpi , 1.65 on the ram. No post at all. Nothing new for me. Just though id try it.

thanks guys for all your imput on this looks like filling all the slots up is not as easy as it looks .....ive not really got into to much changing settings in the bios but ill play around a bit more and let you know what the best i get and thanks again guys
