Super Pi 32M Low Clock Challenge

Try other bios for RE best is 0121.....

[Zeus]

But i have a Rampage Extreme X48, so no Rampage II Extreme.

If you mean bios 0121 for my board, that bios is only good for 1M and besides, i could not change multuplier in that bios.

Thanks for the suggestion though.

[Perica_Barii]

Yes this is the best bios for 1m ....for 32m I always go for last available ...

p.s.
RE not RIIE (RIIE is on the bench table at the moment so I made this typing mistake) ..I made a change on post above..

Maybe i have to kill some services?

More tweaking ahead.

PL8 would make a nice difference. Also try killing some services and chopping off a bit your OS.

[Zeus]

PL8 at 630+ FSB ain't gonna happen for me, at least not with this (water)cooling i'm using.

Do you know what services i can disable to gain some seconds and what to chop off?

I disabled some services with zero gain. Als tried to disable the clock in the taskbar and disable the quicklaunchbar without any gains.

hey guys

just fired up this Asus board as i need to use it tomorrow on a show
and as all Asus boards it gets you suckered into SuperPi lol.....i dont have a lot of time on it but here is a start for 7.xx category

unfortunately this bios is missing a couple of values i need and i havent tested many combinations to see what works best but this sob has some potential anyways heh

why is CPUTweaker locked on this board WTF....


4354.9......dinos22............7.59.985....25x174 ....1045mhz.....7-7-6-20....2/12....X58

Read that it is (or was by now, not sure) not possible to change timings with cpu tweaker on any Asus board.

[Zeus]

My OS must be really cr@p for 32M, i just cannot touch the efficiency of the likes of Kintaro, cheapseats, ToyTen or 3oh6, not even close!

Did a desperate attempt at sub 11 minutes with 4x1GB CSX Diablo.

I was actually able to run the timings as tight as a virgin despite 4 sticks of ram!



Efficiency still sux though.

This time i disabled a hell of a lot services, killed a lot of processes, killed explorer, quicklaunch bar, clock.

Olive theme, maxmem 600, copy waza, pi_rec from cheap, pagefile 512-512, realtime prio, core affinity, etc.

I even uninstalled my ati vga driver!

[Zeus]

Managed to shave of 1 notch of FSB, from 7x567 to 7x566:

[geobot24]

For 16x
4027......geobot24............16.59.344....20x201. ...805.4mhz.....7-7-7-21....1/4....AM3




For 17x
3737......geobot24............17.59.281....18.5x20 2 ....808mhz.....7-7-7-21....1/4....AM3

[George_o/c]

Way to go my friend George
Moar, moar

[geobot24]

Thanks mate!!
One more run from today with lower cpu frequency but with more memory

4977.5......geobot24............16.59.453....20x21 5.....860mhz.....7-7-7-21....1/4....AM3

[Zeus]

After tweaking and trying for almost 2 days i finally am in the same ballpark as the 32M big guns for efficiency. (well, almost)

Still not on top but better than i've ever had it.

I lost count of the number of 12.00.xxx runs i had but i can assure you it was more than 10.



The trick was to set AI clock twister from light to moderate, stopping about 15 services, checking the CDT box of SPi tweaker and some more tricks.

I think i can take a rest now.

hey Old
what cooling do you have on the CPU

I use a SS Phase change
With (chilled) air I can reach approx. 3050-3100Mhz NB.
Up till now I did not test Superpi 32m with air, perhaps I wil do that later on.

[dinos22]

great
dont waste time with air....it's always better subzero

i gotta do some efficiency testing soon when i find a suitable C3 chip and do some comparisons with a couple of different boards

looks like you set some kick ass benchmarks to go by....i like it

That is also mine idea
I had used the setup for the LCC 3DMARK05, so I thought why go back to air.

Which boards are you goin to test and thanks

[dinos22]

giga & asus top end stuff mate
