How not to order RAM

So, back in June or so, I ordered four sticks of 2GBs of RAM for my main workstation, DDR2 PC6400. Couldn't wait to get them right? So, a month goes by and they finally come in. Now, the board I have right now is a Supermicro X6DVL-EG2 which accepts ECC RAM. I thought my current RAM was non-ECC so I said fuck it and ordered non-ECC RAM. Wrong. RAM came in, tried it, motherboard beeped at me. Fuck. So I sent it back out east for a refund (to Newegg). A week or two goes by until I get the refund so I go ahead and order DDR2 PC6400 RAM. Though, when I remember installing the last sticks of RAM, I remember reading "DDR2 400MHZ ECC ONLY" on my motherboard. Ahh, fuck it. New RAM comes in and, oh, surprise! It doesn't work! 


So, now I'm sending it back to Newegg for the second time but I have to pay for shipping ($20) to get a refund. Turns out, the right RAM (PC3200 ECC) is $45 per stick, when the PC6400 ECC was $30. I found a cheaper price on eBay so woohoo. Next time, I'll be more careful.
