A desirable 1:1 ram ratio is, afaik, a relic of earlier times. Your memory multiplier and ram timings are totally different settings, btw. Multipler*FSB = memory speed. Timings are independent of your actual memory speed, though how tight one can get the timings is relative to memory speed only in that improving either of them may require extra voltage and extensive stability testing.
I assume you are using 1333mhz DDR3 (as that would be (10/3*200)*2) so any % increase in FSB (200 to 220 = 10%) will be replicated in your memory (1333*1.10=1466mhz). If you are experiencing any stability issues, a drop in memory multiplier to lower actual speed, or an increase in volts (within manufacturer specs) may be needed.
even i hav the same problem i.e my FSB RAM ratio is 3:10
i havent overclocked my cpu or my ram
i want it to be 1:1
what are your suggestions??
i wud b overclocking my cpu in a months time bt it wud b my first time
so can u please guide me through in a stepwise procedure ??
Check out the Amd overclocking guide at the top of the overclocking section for a start Vangya,
@cosmiconion, have you tried unlocking the fourth core? any luck?
you will see a decent hitch up in performance from an extra core over any clocking but given decent cooling you could see 3.5GHz on that chip with four cores if you are lucky,
