Do any of the following stand out from the others:
Geil Black Dragon PC2-6400 800Mhz 4GB Kit (2x2GB) : gel-bd644g - £64
OCZ-4GB-DDR2-PC2-6400-800MHz-Enhanced-Latency-Gold-Gamer-eXtreme-XTC - £70 from play.com (can't post as link, WTF?)
Computer hardware and software at amazing prices, available online from Scan Computers UK - £67
I think the last two are 5-5-5-18 while the Geil is 5-5-5-15. The Corsair stuff seems to get slated round here, but runs at 1.9v vs the 2.1v for the same spec OCZ - so is the Corsair not better, making it run cooler with more room for voltage increases? I'm not going to OC at first, but may as well get reasonably OC'able stuff at this point for when I do.
