UNOFFICIAL BIOSTAR TPower I45 M/B

[trans am]

your cpu-z and memset screens show p45 with ddr3 some bug I guess/
The first thing you need to do is open you case. Do you have an extra fan laying around anywhere? You are going to need a fan if you want to do this. With the case upright place a fan on the top of you video card. (make sure its a plastic fan or else you will short out the video card). You don't need to mount the fan just let it stand upright and aim it blowing in the direction of your memory dimms. If you have a 120mm fan you should be able to hit the NB at the same time. Once you have the fan going boot up and get in the bios. drop you cpu multi to 7 to take the cpu out of the equation. You want to concentrate on ram clocking now.
get in the mem settings and run 4-4-4-15 to start out. keep rest on auto. increase vdimm .5 mhz and reboot. keep doing this until you can get windows to load. once in windows open cpuz and check the timings . then open superpi and run a 1m run. if it passes go for a 8m run. If you get errors reboot and raise vdimm some more. try not to exceed 2.5v keep messing around. play with nb voltage a bit. start at 1.35 and keep going up. some times lower NB voltage can help. higher is not always better. but 1.5v seems about right for this. if 4-4-4 @500mhz doesnt work at all drop your fsb to 450 and go from there.

7.5 @500mhz 5-5-5 and run a spi 1m run and see how fast it goes
try running multi at 8 x 469 (3752mhz) fsb 1:1 at 4-4-4- and run spi and compare the time and report back

you are discovering the sweet spot of your cpu and now you need to find the sweet spot of your ram so you have maximum performance.
