sorry not sure what you mean now

I was saying that I could improve on my score but there was no way I was going to beat you with your RAM and ln2 when it was all said and done. My RAM just didn't have it in it and my uncore just couldn't run that fast though it might have with better cooling than DICE.

What I want to know now that the contest is over, are you gouing to share some of your jedi skills? All I was using was overclocked install, large system cache and copy wazza. I tried many of other tweaks but they just seemed to hurt my score.

there is nothing magic about my superpi except hard work

i do spend a lot of time getting to know platforms and how RAM overclocks on it and how it all affects superpi though but the tweaks are almost universal with some slight system adjustments needed from time to time

tweaking pi has been discussed to death on XS and other forums and it's basically all been laid out many times. Trouble is that these days tweaks do very little to improve your efficiency due to CPUs having large cache internally. This is what for example wazza helped with a lot with older chips. i remember in good old days some chips could have as much as a few minutes imprvement in time with a good wazza. these days we are talking about 1-3 seconds MAX.

what i suggest you do is actually do some searching on XS and sit in front of your system and try things > GIVE THEM A SERIOUS TRY BEFORE YOU GIVE UP. this is the key. i can memtest for days sometimes until my face turns blue almost just tinkerin with different things

dont assume things > test them yourself and find out >> i'll give you a hint > increasing NB doesnt mean faster pi times

.....it can make it slower when higher NB if the rest of your subtimings are not balanced. you have to find the right mix so assuming higher NB = faster is wrong if you dont have your other timings in order.

test your tweaked OSes as well. get to know nlite and how it all works and what makes a difference

if you put the work in you will get the best results AND whatever new platform comes around you should be able to adapt much quicker than someone else would who relies on others to give them tips

this is the best advice i think i can give for someone that wants to get more serious about their superpi. Nothing wrong with comparing notes with others but you have to get to that stage where you put a lot of work into it and then tweak more out of the system by comparing notes. Thats why i chat with some of my benching friends to work out kincs in my benching no matter what benchmark.....

I hear ya. I have pretty much combed the net for tweaks and ideas and used them to death. What I have found is what works for one doesn't always for the other. I will tell you from the contest I improved my Superpi by 20 seconds at the bot which netted me a 7 min 2 sec run. ALMOST SUB-7!!!!

You are one of the greats at this bench and it was a privilege to go neck to neck with ya if you want to call it that. I was just interested in what tweaks you might have used to see if I have tried them as most of the info out there are for 775's which are a different story. What I found that works best for me is of course a fast overclock on my CPU, high MHz on my RAM with tight timings with of course tight sub-timings. I have many of more runs on this bench and I mean many of more before I consider myself good at it. This bench was once one of my not-liked benches but has become my favorite since I've had my i7 platform.

are you sure man
why are you not running maxmem :S

doesnt look as though you really tried hard enough cause it should have made a difference combined with wazza for sure

you also have vga drivers loaded so who knows how well you tweaked the OS.....you have to make the OS lean for superpi cause you are trying to reduce the amount of processes tapping into your RAM while you are computing pi

all these little things add up as you've probably noticed shaving up 20 seconds which is a great start

DrNip · #**226** 08-20-2009

Couldn't figure it out actually. Still a noob on it and looking for some guidance. I have seen many of tweak write ups on Super Pi but none really on max mem and copy wazza. I'm not the only one that feels that away as I have spoke with others that are clueless on this.

Never heard of the GPU driver thing. So leave them uninstalled or what?

Oh and I tried hard with what knowledge I had on the bench.

dinos22 · #**227** 08-20-2009

start with say
600 maxmem
copy files from one partition to another and then back when finished
use small page file size

OS if its idling too high (used RAM) is a good indication but it this is not really

i always use one of my low end nvidia cards for Pi normally as it seems to give me good times.....ati i always take a hit on donno why

you should be able to shave more

anyways i'll leave you to it

DrNip · #**228** 08-20-2009

This is about the best guide I could find out there and after going back and looking at it for about the 100th time I see how to use maxmem within the guide.

What I want to know is how to use maxmem with copy wazza as I see people refer to this all the time. Do you use maxmem 1st the copy wazza or vise versa?

punx223 · #**229** 08-20-2009

i do have to agree on teh vga drivers amongst other stuff, as i found a fresh install of XP64 ran best... with minimal clutter

DrNip · #**230** 08-21-2009

Come to think of it I do have a ATI 2900 pro card that I could use. Also I was using a monitor with a res. of 2048x1152. Prolly should have hooked up my 1280x1024 one.
