Anyone have any suggestions on how to get the most out of a SuperPi and SuperPi 32m run? Which OS is best? Any tweaks there are that might help? Mine aren't all that great and barely beat out my E8600 runs.
Yeah, I wouldn't think that i7 would do much better in supi 1 or 32. Isn't it a single thread benchie?

Ok nip I had a power outage and I think the surge eat my keyboard on the other rig. That's where all my tweak links are. Pretty much the jist of it is high clocks which you know. Then get your ram as fast and tight as you can, which you already know. The other tricks is what I got linkys for :D
Pretty much the two main tweaks are copy waza and maxmem. I'm gonna give you one link for a proggie that can do all of this for ya in a nice GUI, but what you wanna do for 32m is test with your maxmem set from a range of 600mb-648mb I think. Copy waza is nothing more than making a dummy file of a set size and copying from say c:/>d:>c:/........wait a few seconds watching your available memory start to increase and then start the bench. I'm gonna try and get this other rig back to normal and then I'll bombard you with links which are mostly for spi tweaks ;)

Yes it is a single thread bench, but clock for clock nahelem rules due to the retardedly fast memory bandwidth and reduced latency. E8600 is still 1m king due to the retarded clocks it can reach.

Well the spitweaker is bs. I have tried it a good 10-12 times with no noticeable results. The theme change is also kinda some bs as my quickest time was done with the blue theme. I accidentally ran it in that theme, realized it and switched it to the silver theme for every other run. Each of those was slower than the blue run as well as they were used in conjunction with the spitweaker. I can't call it. I have seen people rave about the utility that it worked. I guess not for everyone. About the only thing that caused a noticeable difference was dropping the mult and raising the blck same as with the 775 but raising the fsb.

Good lookin chuch and good lookin on the last tweaks as well. I forgot to say but I did manage to go from 9m 89s to 9m 03s on a 4.2ghz clock. You ask how? Well I reloaded my hdd and upon doing so I realized that I forgot to do a defrag on my last install. Upon doing it on the new drive it noticeably gave me a boost. I also did the install with a 4.2ghz overclock as I saw online that installing with an overclock somehow improved runs. So that is where I am at.

Improved my time by about 1 minute. I used Vista 64 at that!!! I used the classic theme in it and it seemed to love it. More than XP. Maybe that is the ultimate tweak. Not going to upload this to the Bot as I know I can break into the 7's.

Man, I see why i7 is the king of the roost. I'm looking forward to learning the new ways of teh force ;)
Surprised no one has mentioned this. On Nehalem, 2GB sticks are 4-6 seconds faster than 1GB sticks everything else equal.
maxmem=600 is a good value to start with.
The gains from CW aren't huge, usually a few seconds. I'd start with 1896MB and CDT enabled. This provides some gains on most systems but can still be heavily tweaked for further improvement.

Nip.
Only tweaks I know about are all for 8M or higher. 1M really there is nothing you can do but get taht CPU speed up.
32M is very memory reliant, so getting that running great is helpful
The thing that spitweaker is trying to do (incorrectly) is the old copywazza trick.
Have 2 partitions on your bench drive. And grab one large file from your second partition to the SPI partition. Then run your bench. Most popular file sizes I have seen are 5GB and 7+GB.
Setting PF to a second drive in the 80-90MB range is helpful, as is the maxmem=512 tweak.
The theme tweak aleady mentioned also.
Bear in mind I have done none of these, but will try them all before I go extreme cooling.

Let me clear a few things up...
There are quite a few tweaks for 1M ;)
Copy waza is a completely system subjective tweak. There is no hard and fast rule for what will work. Also you want to transfer from pi drive > non pi drive > pi drive. Maxmem is similarly system dependent 512, 600, 640 all have different characteristics as to how it affects 32m.
Superpi tweaker was made by an awesome pi bencher with input from some of the best in the world. There is *nothing* wrong with it.
Use silver luna for 1M and olive luna for 32M ;)
Pagefile doesnt help my scores at all, but if you implement it the most common value is 512MB PF on non-pi drive.

I was just regurgitating enough that Nip could google the stuff he needed. Since no one else brought it up... I felt obliged :)

Tried out spitweaker. I am a n00b and it added 6 seconds to my pi time.
My old faithful trick on 1M seems to work with 32M although the second trick does not .
I run 16k twice before running 1M. Than I run 1M again. makes a nice difference.
2x16k before 32M seems to make a difference of a few seconds on 32M (for me dropped me from 18m 37s to 18m 31s) as well. running back to back 32M though was slower. Tired of running it right now LOL I think 6 hours of Pi is enough for one night. Asus board is crap, 2350ish is my max NB speed. Again my cheaper crappy foxconn board does better WITHOUT having CPUNB controls *sigh Time to upgrade.
Happy enough though. My first 32m time was almost a full minute slower than my current best on the same hardware :) I nice ~8% improvement overall :)
EDIT: Oh maxmem and system cache mode definitely helped :)

@neuro- the "run 16k a few times" trick works best when you get a time of .094s or faster. This is due to the pi_rec2.dat (or something similar) file it creates when running 16K. There is yet another even faster pi rec that can be created by runnning 16K, 128K, 1M, and (possibly) 32M I havent hashed out the right times for it yet though. But it boosts 32M by another few percentile.

so you wazza then run 16k a few times or run 16k a few times then wazza?
DrNip
08-19-2009, 07:22 AM
I run wazza then do the 16k a few times until I get a way lower score than the normal 16k run.

You use spitweaker waza or just regular copy a file over?
Reason being I noticed that Spitweaker makes a large files consisting of a bunch of small files. When I first heard about the waza trick it was recommended to use a DVD ISO or something similar. One single file over 4GB. (I have since read that the file size is entirely subjective, I will be trying out some of my BD reencodes next time I run Pi though)
Wondering if my decrease in performance using SPiTweaker was due to file size, noncontiguous file size or I just did something wrong lol

I am using OCXtreme SpiTweaker. My file size is anywhere from 1600MB to 4000MB. I will be posting my findings on this utility as soon as get get my testing done on it.

Not a known issue buddy... ps2 or usb? and what model KB?
what Bclk?

It's an intermittent issue and could be the generic keyboard, thats why I asked. Usb keyboard, refer to screeny for settings:

WOOOOO WHEEE!
Thank you thank you thank you guys for all the awesome tips :)
Between this thread and the other superpi thread, I managed to seriously enhance my scores!!
And I find out that yes 1M is effected pretty nicely by tweaks :)
Unfortunately crashed getting 17 seconds flat at the same clock speeds I was running last night :) (It is a little warmer in here) but got enough progression shots, and managed to shave another half second of my time from last night (17.59 at 4030 MHz)..
"But WAIT there's more!"
Managed to shave another whole MINUTE off of my 32M time :)
Tweaks used
Windows Fundamentals for Legacy PCs. Full install, added DirectX SP3 and updates.
System cache mode
(checked out Blutos recommendation about large cache... it was already enabled)
192MB pagefile on USB stick.
MAXMEM 800
Olive Green Luna
Kill Explorer
Set affinity to core 3
Set priority to realtime
Run 16k for oddly out of place great score (last two loops identical)
Run 1M
Run 1M again
Bump it up a Mhz and run again and again. find a good one restart and go again and again :)
Same exact process I used with 32M. Except I added Waza
Put a 8.2GB video file on 3rd partition on same drive
Restart, run SpiTweakers cleaning program
Copy file to C: drive
16k 16k 1M 32M
Awesome results :)
Btw.
Apparently the number one top spot for my AMD 920 in 32m was a single stage.. Now its an Air cooler!!!!
Going to hit up Wprime tomorrow, I think a lot of the tweaks carry over, keeping my fingers crossed :)
I did forget one thing I did tonight that I saw mentioned in the "living" spi guide.
I went to defrag with windows defrag, and it said chkdsk was set to run. (40% fragged yikes!) So i rebooted let chkdsk clean up a million errors LOL (yeah been riding this HARD) Then I installed O&O Defrag and ran complete/ACCESS defrag. Rebootski and than followed the other steps.

unfortunately wprime is not exactly a bench that benefits from any superpi tweaks and for that matter any other tweaks :(
if you find something that will speed up wprime you are doin well lol

Killing explorer.exe kill my score by 2 seconds or so. What you need to do is try a a run with and without teach tweak to see if it benefits you or not. Of course I have seen reports of killing explorer.exe helped.
About the only thing that I found to speed up w/prime is faster cpu clocks.

Yah probably right. I was going by the marks received by the SS cooling guy for my CPU. Which led me to believe my tweaks were responsible for my Cups. But I see that he just was not optimized for it and running too close to instability I guess as his scores suck per clock cycle, and the rest of the guys benching the 920 seem to be pretty even as score per clock goes.
There are exceptions though. I will probably just continue to bench 2D after SuperPi though just to keep things rolling.

I gotta agree with nip on this, not all tweaks work the same, hell 2 different ram sets even at the same settings seemed to respond differently to killing explorer

A good few seconds I think. I was not methodical about it (really should keep a journal) just kept adding tweaks, I have not tried each one individually yet. I started with the simple ones system cache and maxmem, than I tried spi tweaker.
Next big jump was Prioirity. That really seems to help. Affinity and Luna theme both happened at the same time, but I jumped a good 2%.
All said an done I cropped a minute of my sPi32M time from these tweaks. Just looking through my screen captures I have 3 32m runs saved. First at 18m 38.812 seconds
Added Green Luna and most everything elses got me down to 18m 17.406
Ran chkdsk, than used 3rd party defrag tool. Reboot, can spi tweaker cleaner. Than ran pi soft clocked up another step ran pi again soft clock over till I found fail point
restart, waza a 8.25GB video file and ran again but this time clocked straight to just under the fail point.
17 Min 38.921 seconds.
