I do not recommend this memory due to the fact that I had it in my system for about a month before it died horribly. I found that set in stock at newegg in late July for $489 and jumped on it. With stock voltage and 4-4-4-5 timing I was able to hit DDR2-1120, which put my X2 3800+ to 2.8GHz. These settings were stable for normal operation, but to pass a 24-hour stress test of two instances of Prime95, I had to back it down to DDR2-1108 (2.77GHz CPU).
This was all good and well until a month later when my system started rebooting randomly and frequently. I tried dropping back to stock speeds and that didn't help. I ran Memtest86 on each DIMM individually for 12 hours each, which found 1403 errors on one DIMM and 9404416 errors on the other. I RMAed them back to newegg and received a refund since they were out of stock. Then I bought an OCZ Platinum 2GB DDR2-1000 Cas 4 kit and have been running steady at rated memory speed (2.5GHz CPU) since then. I'd like to see how the OCZ memory overclocks, but for now I need the system to be reliable (at least until this semester ends).
Anyway, I see no reason why this memory should have quit on me since I didn't touch the voltages and my cooling system is ample. Also, if the memory dies more than a year after you buy it, newegg will not take it back, which means you get to RMA it to Germany. For these reasons I would suggest going with something else from OCZ or Muskin (I hear the Redline 2GB DRR2-1000 Cas4 kit overclocks well).
Also, here are some screenshots to back up my experience claims:
