I have a pretty old motherboard, a P7P55D-LE, an i5 750 and originally 2x2GB Crucial Ballistix Tactical 1333Mhz RAM, rated at 7-7-7-24 and 1.65V. I've run this rig for 4 or 5 years with all BIOS settings set to default. As it happens, this means I've been running it this whole time at 9-9-9-24 and 1.5V, but I've never had any issues.
This week, I bought another 2x2GB set of the exact same RAM. I haven't had any problems booting, but I've been getting frequent BSODs (with many different error codes, mostly 24 and 1A) and general instability (very frequent Chrome "Aw, snap" errors, extensions crashing, programs closing themselves etc.). However, on occasion, I have been able to use the PC for hours at a time with no issues whatsoever, including playing Battlefield 4 for several hours at a time. In general, the system seems least stable when turned on in the morning, and becomes more stable throughout the day / through use.
I ran memtest on the new RAM for about 8 hours, completing 8 passes with no errors. I do not believe the problem is with the memory itself. Following suggestions for people with similar problems, I've increased the DRAM voltage from the default 1.5V to 1.6V (my motherboard only allows increments of 0.1V for whatever reason, so 1.65V is impossible and 1.7V is of course too high for my CPU), increased the IMC voltage from the default 1.1V through 1.15, 1.20 and 1.25V, loosened the RAM timings as far as 10-10-10-27 and lowered the clock speed to 1066Mhz. Apart from what seems like a slight overall gain in stability from upping the DRAM voltage, none of the other settings seem to have any noticeable impact.
I have no idea what's going on here. The BSODs seem to have become less frequent since I first installed it, but the Chrome errors are still happening quite often. Is it possible that it will settle over time, and is there anything else I can try?
