The Intel DP67BG is somewhat of an annoying motherboard to work with when it comes to RAM on occasion, but the problems / bugs can be solved. Well, at least the one I had.
This post assumes that you have some power user knowledge; the issue is unlikely to occur if you’re not using a custom build anyway. By now, a custom build with 5 year old tech too. Heh.
After adding RAM, your computer beeps briefly once at startup (you might hear more beeps), and refuses to even get into the BIOS. This is Bad. (you can now skip to tl;dr version at the bottom).
The potential cause:
If you’ve increased the speed of your 1600mhz memories (commonly done using something called XMP or Extreme Memory Profiles) from the initial 1333 the Sandy Bridge processor (in my case, an i5 2500-k) enforces, this is likely your problem.
There is also a new BIOS version you can flash (easy using Windows) which claims to fix memory issues. Didn’t fix mine, but may have added a certain option in the BIOS. Aight, back to non-tangential stuff.
Remove the extra RAM you put in if it’s still there so you’re in your previous stable configuration (if it still doesn’t work, consider resetting your BIOS settings the hardware way), then set your memory speed back down to 1333mhz from 1600mhz in the BIOS. Add the new RAM, and the computer should now boot.
If you’re having trouble getting into the BIOS settings, pressing the Back To BIOS. / B2B button that should be on your motherboard’s I/O panel will work, otherwise I think it’s accessed through spamming F10 at the right time during boot.
Assuming it does, we’re left with a question: how do I get XMP working again? 1333mhz is lame. Shimpuru, amigo. Changing the speed using the BIOS’ manual 1600 setting will cause boot to fail again; instead, you want to select XMP 1600mhz from the profiles list up top (you can tell by the manual options turning grey.) Reboot, and hopefully your issues will be gone. Good luck.
Set memory speeds to 1333mhz in the bios, add new RAM, to set 1600mhz again use XMP profile up top in the BIOS settings instead of manually forcing it, reboot, cheer. Flashing a BIOS upgrade might be a good idea if something’s off.
I was adding 2x4gb RAM to a system that was originally booting fine. The problem, as it turned out, was memory speeds. The RAM used (in all slots) was G.Skill RipjawsX 1600mhz, which was commonly recommended for the processor in question.
The lede only really mentioned “bug” for SEO purposes, I doubt it can really be considered one. Not like SEO is going to matter though ‘:).
