Never used AI suite, nice to know.

Hi

Just been playing with hitting 450Mhz and thought would share findings:

Static RAM control - seems to change two settings
1) decreases performance level (tRD) by 3 (ie when transaction booster is set at relaxed,0 tRD is 10 with SRC off and 7 with SRC on)
2) changes Read Delay Phase Adjust from Neutral to about +29T (varies depending on FSB - 29T at 450, 25T at 440).
3) Max tRD as predicted by the AnandTech formula does not POST with SRC enabled. max-1 does.
4) Everest memory bandwith is similar between tRD-1 with SRC on and tRD with SRC off (ie at 450MHz tRD6 (max) SRC off = 450Mhz tRD7 SRC on)

The combination with SRC on is also more stable as SRC on, trans booster relax,0 (gives tRD 7) and increasing FSB termination voltage to 1.2 allowed me to hit 450 stable for the first time (other settings stock - http://www.xtremesystems.org/forums/...postcount=1182), although vcore needed to go from 1.2750 to 1.3000 for that small increase from 440MHz FSB.

Now to try 460! (any hints! )

I'm not using the same cpu so this may not apply but I need a PLL of 1.6v and and FSB term of 1.4v to achieve 500 fsb. t-booster is at auto which results in a perf level of 11. These settings will allow me to boot at 525x9, and semi stable (spi 1m) at 500x9. I haven't manually adjusted anything that you've mentioned so far and remain stable at the clocks in my sig. (475x9)
