Then again, the only 512MB I can see here [http://www.overclockers.co.uk/acatalog/Corsair_XL.html] is different from the 2x512MB so I can't be sure.

This one:

Corsair 512MB DDR XMS3200XL Pro CAS2 (CMX512-3200XLPRO) (MY-065-CS)
Corsair XMS3200XL Extreme Low Latency uses the best chips - pre-set to aggressive memory timings of CAS2-2-2-5-1T - for those who'd rather not experiment with BIOS settings and what the absolute best memory timings. Featuring an efficient aluminum heatsink to dissipate heat and built in LEDs to show realtime memory activity. This memory uses Samsung TCCD chips which are extremely good for overclocking.

is the one I was thinking of getting but it's sold as single units.
Whereas this one:

Corsair 1GB DDR XMS3200XL Platinum TwinX (2x512MB) CAS2 (MY-049-CS)
A matched pair of 512MB XMS3200XL Extreme Low Latency (2-5-2-2) memory modules - 1GB total - ideal for dual DDR motherboards. This memory uses Samsung TCCD chips which are extremely good for overclocking.

Is already twinned.......... and so might be the safest option
