$40 for 2 x 1 GB, and timings of 4-4-4-12... would the 4-4-4-15 OCZ be better at 2 x 2GB than the tracers 4 x 1GB? Do you're timings get worse from having 4 sticks versus 2? or is it just better having 2 sticks instead of 4, so you can eventually go up to 4 x 2GB = 8GB...
The reviews for the reaper say this
----- i bought this ram for overclocking in mind, but i found it wont oc very well, even with voltage increse, and loosened timings, but i still have my q6600 @ 3.6 24-7, and 4+ for benchmarking.
----- Need to back down to 5-5-5-15 if you want it to run faster.
Other Thoughts: Might not fit in your rig if you have one of those massive CPU coolers. My Tuniq 120 hangs over the 4th mem slot and this won't fit under it.
