I've had an ongoing issue for the past couple of years. I've approached G.Skill's support via email and gotten extremely great responses but the problem still exists. I'm hoping by posting this on the boards that another user may have come across these issues and have a bit of insight. Essentially, my system's stability is quite random within Windows while running with 8 GB of memory. I'll get occasional oddball errors (printers disappearing, memory errors, etc.) which eventually will lead to a blue screen. I've had this happen with 3 different operating systems:
Windows XP 32-bit
Windows Vista 64-bit
Windows 7 64-bit
If I remove 2 modules from my system, dropping the total memory down to 4 GB, I never, ever have issues at all. It doesn't matter which 2 modules--the issues never happen until I install a total of 4 modules.
The instability is almost immediately apparent after turning the computer on. If I reboot the system 2-3 times, eventually it will become stable and run for days without a single issue. I've even gotten everything stable after a few reboots and been able to run Prime95 over a 48 hour period non-stop with no errors. As soon as I power it completely off, then power it back on, I have a random chance of the instability issues occurring.
Prior to the ASRock motherboard, I experienced the same issues with an ASUS P5Q3 motherboard (two of them, I RMA'ed my first one thinking that the motherboard was the issue). I've also gone through 2 power supplies thinking that the old one was possibly faulty. So far the only things I haven't outright replaced with brand new parts has been the CPU and case. I've determined through my testing that the current modules are good, seeing as how they work just fine in a completely different machine and never cause crashes there.
I've tried adjusting the settings within my BIOS, but the system becomes extremely unstable when I set anything manually. So far I've only adjusted them as instructed by G.Skill support, so I'm not just setting things randomly. I've had a couple of the pairs of memory I originally ordered RMA'ed through G.Skill previously but the issue still persists.
Now, here's the oddball part of this scenario--my wife's machine is a similar build, with ASUS P5Q3 motherboard, similar power supply, same processor and operating system (currently Windows 7 64-bit SP1). I can use any combination of the modules I have in her system and have absolutely 0 issues.
I've updated my motherboard BIOS to the absolute latest available, but this problem still exists. Honestly all I want is a stable system with all 8 GB of memory installed at this point. Has anyone else experienced similar issues and found a way to fix the issue? I have a strong feeling this has something to do with voltage settings but it seems like the best case scenario comes when I leave everything to default or simply stay at 4 GB of memory.
