NOTE: I been running this config for the past year and stable O/C @ 3GHZ till i installed this mem and temps are good.
Memory Dram freq 416.7mhz
FSB: DRAM 3:5
I heard the BSOD code 124 results from O/C low voltages, hardware, etc. I ran memtest86, memory is OK.
So my guess would be the voltage, but which part?
The memory XMS2 default is 1.8v and now its at 2.0v and I heard should not go beyond 2.0v corsair.
Some RAM does not play nicely under certain conditions especially when Vista or Win 7 are involved. If your new RAM is not matched to any existing RAM then problems can surface there. Your BIOS may require an update. You can also try taking the RAM back and swapping it for another brand. Sounds strange but I went through this with a laptop. Upgraded it using the same brand of RAM it already had to 4 GB. BSOD. Changed both modules to another brand and all good since. Sometimes its is a matter of experimentation.
Back the voltage to 1.8 or what ever the manufacturer recommends. Then set your ram to a 1:1 ratio, the lowest set speed. See if it crashes, I would set pci to 100 as well, no need to leave that on auto when overclocking. Some motherboards need a little bump in NB voltage depending on build quality and how many dim slots are populated.
@ henydiah, Prime95 all 3 test stable and OCCT.
@ sportsfanboy, Now set to 1:1 @500mhz 4-4-4-9, 2 dim slots both populated dual channel. FSB is at + 0.2v max is + 0.3v and PCI Auto is 100. I will set back to 1.8v current 2.0v if doesn't bsod
