How do i compensate not having L3 cache ?

I was wondering what I could do to boost performance without having L3 cache memory. Should I increase my RAM memory, get faster sticks get turbo memory (not!) or overclock my current memory, I have DDR2 1066 on an Athlon II X4 @ 3.5 GHz with no memory divider so the ram's at 1000MHz. I've found that my ram latency goes up with FSB so I can run it at stock CPU and th RAM would be at 1066MHz but it would still have a much higher latency than if it was at 1000Mhz with my processor overclocked. Anyway, opinions please :)

the lack of L3 cache is probably not even affecting your performance that much

i would run the ram at DDR2-1000 with the lower latencies as the 66MHz probably won't make much of a difference compared to the loss of timings

What about ReadyBoost? I don't know where USB 2.0 flash drives lie on the scale of data transfer speed. I think it's slower then RAM and I know RAM is slower than L3 cache but maybe I'm wrong on the first point?

well, DDR2-800 ram is 6400MB/s and 12800MB/s in dual channel (DDR3 is even faster)

i think the fastest flash drives would be topping out at 35-50MB/s on usb 2.0, so thats not too helpful really

though like i said, L3 cache doesn't affect performance too much, good ram with good timings work fine

You DO HAVE AN L3 cache you need to enable it in your bios if you read the documentation that came in your cpu box you would see that it is a feature.
