Odd behavior - memory related?

Running memory above the "stock" speeds can introduce errors.
You can run "memtest86" to test out the memory to see if there any faulty sectors.
Do this at the *stock* speed.
Not all memory can be overclocked to the max, and even different batches of the same memory can have different overclocking limits (or even non at all)
OK first of all he is running the memory at stock speed - its 1600MHz memory.
Yes bad memory could be a possibility - it could also be counterfeit memory where it is being relabelled as higher spec than it really is.
Other possibilites though are the other memory settings are being exceeded - e.g you have high latency ram but are trying to run it at low latency settings.
Another possibility is by increasing the memory bus speed you may depending on the motherboard have inadvertantly overclocked other parts of the system in particular if you overclock the card busses the timing signals for things like video cards may be totally wrong.
Look out for setting in the BIOS to allow you to set these independently and check the values keep your busses within spec.
I'm also assuming each memory module is part of the same matched set and you don't have a second set of memory modules installed.
Note that strictly speaking the memory modules don't need to be matched but if they aren't then you will need to restrict settings to the lowest of all 3 on both clock speed and latency etc settings.
Mind of Gaia lvl 50 Defiant's first Mind/Storm 'troller.
Deadly Doc 50 Dark/Dark Corr
and lots more on Pinnacle,Union and Defiant
Yes, the 3 2GB modules are the only ones in the system and came in a sealed box from Microcenter.
I agree with Gangrel that overclocking could cause these problems, however, I get the same issues at stock speeds/settings and overclocking SOLVES them (until next reboot). That is really the bizarre part to me.
Thanks for the suggestion on memtest86, which I assume I can download safely from www.memtest86.com (or is it memtest86+ from www.memtest.org?).

-When I first built the computer, CoH fired up fine! Huzzah! The default BIOS settings were 1066MHz/Standard Profile (those are two different settings) in the Memory section.
-I decided I wanted to try speeding up my memory in the BIOS so I restarted, and went in to set it at 1600MHz/Extreme Profile. It booted up fine and showed the memory running at 1600MHz. However, running CoH resulted in several crashes and a few BSoDs with errors specifying memory addresses.
-I figured my system couldn't support the faster memory. I was disappointed, but couldn't really tell the difference anyway so I restarted and changed from Extreme to Standard (left it at 1600). Worked like a champ...
-...until I restarted. Same problems. Lowered it down to 1066Mhz. Worked again.
-...until next time I restarted. Now, I was getting a bit frustrated and tried a few things, but what seemed to fix it was RAISING the memory settings back up to 1600MHz/Extreme! I ran fine at this setting for a while (leaving the machine on for weeks) until yesterday when I had to restart to apply some Windows Updates.
-This time, it was not so obvious. I tried updating the game client for the patch yesterday and kept getting Checksum errors. I tried deleting the checksum, deleting piggs, etc. Nothing worked, I would get an error on every exe and pigg it tried to verify. I then went to the NCSoft support site and read "If you still receive the checksum error at this point, the error has also been linked to a firewall or faulty RAM."
-Faulty RAM!?! That sounds like me. Went back into BIOS, dropped back down to Standard profile and the updater and game run fine.
So, could bad RAM explain this? Has anyone seen anything like this were the specific settings don't matter, but changing them resolves issues? Can anyone suggest any tools or steps I should try? It seems very bizarre, but I wanted to get some opinions before I RMAed the RAM.
