It's just that ddr2 is so expensive. I would consider it, but I can't imagine what an 8gbs of ddr2 would cost today.
They have been expensive for a few years. I paid $330 for the last 16GB that I bought two years ago.
Also about the timings. Will loosening the timings make it slower and should I start looking at different ram? I don't know how or how much timings/frequency affect speed.
You'll never know unless you run benchmarks and then find out that the performance dropped by 0-5%, depending on the benchmark.
Also speccy is telling me the current timings are 5 5 5 15 while newegg is saying default should 5 5 5 15. I'm pretty sure I didn't change them in the bios so why are they like that? Anyway in that case 5 5 5 15 should match that of the g skill right? But you said due to the voltages I would have to lower the timings?
You need to lower the timings, e.g., 5-5-5-18, 6-6-6-24 only if you have issues. My DDR2-800 16GB kit runs fine at 5-5-5-15 and 1.9v instead of the default 1.8v. You are using DDR2-1066; getting 4 modules stable may be a bit more difficult because they are overclocked.
