Hrmmm... Going with a 146 means you'll need to get some high frequency RAM. Kempez is selling a pair of 512mb OCZ Platinum Rev. 2 sticks I think, that's by far some of the best high frequency overclocking memory you can buy.
To be honest it's going to be hard to find you "budget" memory that will do the trick for overclocking a processor with such a low multiplier. You need to have anywhere between 100 to 125 gbp set aside for a good set of memory...
SysXtreme sells a good lineup of OCZ memory you might take a gander at
