I have a Maximus Extreme Motherboard and it's worked fine with 2 1024 modules of Corsair DDR3 XMS9 DHX 1333Mhz. I bought another 2 modules of the same memory but of a different size namely 2048 bringing me up at 6GB of RAM. I started getting a lot of blue screens in Windows 7. I tested all modules individually and the 2048 ones had a lot of errors. So I went back and replaced them. Same problem. I noticed the system on the default Bios settings wasn't recognizing RAM correctly. The post bios message said the ram was actually at 1033 Mhz. So I adjusted that in the bios. Only change I made. I set the DRAM to 1333 MHZ. The system is more stable now but I still get certain errors. Images downloaded sometimes have corruption to them, crashes back to desktop in some games, browser errors. Not too many but enough to be annoying. I need some help. I should also mention the the modules are of different voltages.
I guess the most important thing I noticed lately is that when I turn on the computer after it has been shut down for a while I get blue screens and errors in memtest. 10-20 minutes of the computer being one and it becomes a lot more stable but I still get the errors mentioned above. Thank you.
this is a link to a forum post where a guy nighthawks has a similar issue and it's the closest thing i've found on the internet. I have also seen some posts about this motherboard having some issues with 4 modules.
I have updated my bios to the latest version and have contacted corsair support but they wanted to replace the modules and it's more expensive to send them than it is to buy new ones.
I will test in the morning again with just the 2 2GB modules with memtest to make sure that the problem persists.
ok so I memtested only the 2GB ones again this morning and as soon as the test started I was getting errors. so all this took about a minute or two. I reinserted the 1gb ones turned off the comp turned it back on and it's back to being somewhat stable. just like that.
everything in the bios is default... so the voltage is on auto. I meddled with it a little in the past and set the voltage to 1.8 to the RAM and 1.45 to the NB trying to fix them. They were behaving like this before this though.
I've got this feeling that they are not defective because of the post I linked above. This guy had the exact same problem but without having 4 modules. Just 2GB ones and we have pretty much similar systems only difference being I've got E8600 while he had E8400.
Is it possible some AUTO settings in the bios are causing this?
