I tried every possible troubleshooting method i knew, losen timings, running at 2T, Dividers etc... but I can only get it to run stable at 240MHz (considering that this ram is rated at 250). It won't even post at 2600.
Your motherboard is struggling to run 4 DIMMs, that's not uncommon. Yes, 4 sticks is harder on the memory controller on your cpu, but it won't lower your OC enough to be a major issue. The cheaper route is another motherboard and that's what I'd do, but that's just me. I'm more conscious of gpu OC than squeezing an extra 100 mhz out of my cpu because it doesn't matter for 99% of games.
