i just cant make out whether i do have a ddr2 ram with fsb 666mhz or 800mhz
and what does 2R*8 as shown in the snap imply?????
is " 6400 U " d latency???
my bios doesnt show d fsb so my notion of having an upgrade has been stalled....plz guyzzz help me out...i m pretty stuck
finally should i buy a Transcend 2gb DDR2-667/PC2-5300 or a Transcend 2gb DDR2-800/PC2-6400 ???? Hynix isnt available here so cant have d same manufacturer...and is G.Skill better than transcend for working with hynix[[[ d one shown in pic ]]]]
thanking u all in advance... :)

6400 means it runs at 6.4GB/sec and the U means it is Unregistered (normal) RAM, which does not add an extra CAS latency cycle (which most server RAM does, as it permits having something like 192 GB of RAM on one board these days).

6400 for DDR2 would equate to 800MHz (or 400MHz DDR).

666-12 on that sticker is the timings, not the clock speed (it almost never is FYI).

The 2R means it is 2 ranks by 8, 4 ranks by 4 by 128 is usually faster/better but not all motherboards support it.

It looks like quite common stock DDR2-6400 to me, the timings might be slightly better than the worst case.

That small chip, just above the notch to the right, is the SPD chip which lets the motherboard 'query' the module so the BIOS can automatically...

As for your 2nd question I would personally go for the G.SKILL, and make sure that you get a 800MHz (6400), unregistered, module that is 2 ranks by 8 by 64 (instead of 4 ranks by 16 by 16/128) which 99% of G.SKILL modules are.

You'll get better 'mismatched module' performance this way. ;-)
