[Update 25/11] 2GB of DDR2 for overclocking what to buy

[Rone]

Then that means 1.8 = pc2-1111. Nice

Actually the PC2 rating would be PC2-8888 but yes, 1.8ns equals 555MHz (DDR2-1111).

So would you be expected to find something like a -1.8F or -1.9F on the new 1066 modules?

Yes, Ballistix PC2-8500 has -18F markings on its ICs.
