[Coolaler-OPB project ]The secret of running super pi faster than you think?!

[Coolaler-OPB project ]The secret of running super pi faster than you think?!
OPB told me last night ....
First of all, we need to find where we need to set the value of we need
The 600mb value key in here under the boot.ini advance setting is the key to the road

So when you initialize the super pi .exe, you can see the real memory size has been changed,to the setting I did under boot.ini
and the result is 10.187s

now, let's go on to the 3rd picture here
This is the original setting without change the maxmem
I got result of super pi 1m for 10.203s,and I did run the 1m all over for 5 times
all the results show me , they are really faster than original non change setting

If you got some time to kill, you guys can always play this,
I think 32m calculation would have greater difference than 1m.
Special thanks to opb assist me about this project and verification.

Great run Master,
Now you know some secret that how JP friends get on the top rank;)
sometimes you just can't figure it out why you have same memory timings setting and same speed even with the same tweaks, but you just can't even come up with those type of score .

this is kinda very old trick, PTJ is using this like forever, and they always say they do.

p.s. and there is also hideo's copy waza if you haven't heard of?

Good to know by all means, thanks for sharing this with us :)

yes, even though they told that long times ago, but they kinda not willing to share about what volume 32m should place in,especially cpuloveclock san
but ya, I mean that's no offense, we just wanna everyone have "know how but not close own door and try that ;)

I got a bigger jump using Maxmem set to 104MB. If OPB and Coolaler get better times using 600MB...I wont argue, you guys are in a different league :D

Copy-waza gave me a massive boost (0.3-0.4 secs, 1M) I have a folder of size 1.2GB I copy to my C partition before running SuperPi.

With both these tweaks...the first run shows the biggest boost, extra runs will show a higher time.

:D

K

104mb didn't work for me either, PTJ is using around 600mb for quite some time.
Now you have to try ram disk and realtime and you on PTJ level :D

same here. i tried some other values before but this one was the best so far.

Yeah you may feel that we Japanese OC'ers are not willing to share it,
but at least hideo had described his basic idea/hint in my BBS 8 months ago:
http://www.oohashi.jp/c-board/c-boar...ne;no=3948;id=
# "パパ" is hideo's another handle;)

Another trick is to use an extremely Light OS for the 32M runs.

Conroe/Presler/Prescott will not run faster in SPi with prio=realtime & set affinity.
but AMD's chip and Yonah are very very much like those tweak.

Actually on both Presler and Conroe i've notice a nice boost from priority = realtime. Win Xp SP2 diagnostic mode, 3.6MB Ramdisk.

Copy waza 0.3-0.4s? :confused: Tell us :slap: :D

Personally I read this hint from PRTeamJapan when he did WR on 32M and the other......

Nice to see you guys are sharing these things for guys who missed before.

Anyway, my settings:
104 for 1M
200 for 8M
600 for 32M

copy-waza gave me really high boost for 8M and 32M, really didn't try on 1M.

Well...consider also that, IMHO, on 8 and 32M (anyway..on long runs) read/write speed on HDD is important...so consider using a virtual drive on your ram...
again the hint comes from Fredyama, same topic...search for eram

:D:D

I must say that with superpi runs on FX57, kyosen explained quite a lot of tweaks, prob all that he uses, he even gave links to tools he used, that was very nice of him and alltogether i got quite nice boost in my superpi times.

Xtreme Tweaking!!! :D

Wow, very intresting:woot:
I will try soon:D
TKS:toast:

thanks for sharing . once youve set it to 600 ,will it remain that way after shut down? or does one have to do it everytime one runs pi?how does it effekt 3dmarks?

it remain because it's written in the boot.ini file.

Very nice tweak/trick...will keep this one in mind.

I was pretty excited with I saw coolaler and OPB in the same thread title.

My best score was done with 108 and i think that's the best for me... :D

I think that each test could have an optimal maxmem, at least an optimal maxmem range. For example, maxmem=104 could be fine for 1M, even 2M, but not for 32M. For 1M i've even used Maxmem=60~65MB and, at least for me, was the best, BUT that was in a very tweaked system (no diagnostic mode) in other configurations can kill the performance.

Like Masters Coolaler/OPB pointed, always check your Real memory, available real memory and of course Allocated memory.

it will remain until you change it. For 3DMark
in my case i've never used, i think that Japanese Masters have a best answer

what is this program?
http://www.iamxtreme.net/coolaler/WR/x6800/5G3.gif

its just msconfig lol...

start > run > msconfig and hit the boot.ini tab then advanced options

Thanks. Damn this slows the computer down heaps. is that normal?
