Try and experiement with different maxmem settings too 512, 600,640, 670... also play with the waza file size in spi tweaker. 1024k and 512k are my favs. And remember higher available memory doesnt necessarily mean better waza, but it can indicate that (verify with final scores). Sometimes the "CDT" or "IV" options have helped my times so try those too. Most of pi tweaking is system subjective so you will have to experiment with values, until you find what your OS/bios/etc likes. Just my $.02

Thanks karmakazi! When this comp is over I plan on playing lots of 32m. I really wanna learn the ins and outs of this bench.

It's actually the System Cache ;)

From TechNet:

Windows allocates a portion of the virtual memory in your system to the file system cache. The file system cache is a subset of the memory system that retains recently used information for quick access. The size of the cache depends on the amount of physical memory installed and the memory required for applications. The operating system dynamically adjusts the size of the cache as needed, sharing memory optimally between process working sets and the system cache.

And why Wazza is effective:

Frequent cache flushing might occur if data is written to the disk frequently in order to free pages

If your running on XP/2003, open Task Manager and you can watch it grow during CW file copy.

Thank you so much GHZ. I like learning my own style to tweaks, but I'm one of those wierdos who like to understand WHY I'm doing what I am. Now I can visualize what wazza is doing when I'm using it.

The Many OS software tweaks of SuperPi Exposed
Submitted by Johnny Bravo on Sat, 04/05/2008 - 01:26. Guides
Over the years there has always been various tweaks touted and spread over overclocking forums on how to improve benchmark results. One area this has been quite prevalent in is SuperPi. We see one guy try something different, get a faster time and suddenly everyone's trying it for themselves. Too often we simply try the newest thing with no real understanding of what it is doing and how it is supposed to help our times. Then when we don't see any real gains we are left wondering what all the fuss is about or why it works for some people and not us.

What I propose here is a thread in which we can all input our findings to test these various tweaks. Each week we shall choose one tweak - specify a platform and run various SuperPi sizes (1M, 2M...) and hopefully through numbers we will establish what gains if any that tweak brings.

To begin with I ask for you to suggest any additional known software tweaks that are commonly used. I have made a list of the ones I know of so far but am welcome to suggestions as we go on.

Known tweaks

XP or 2003 Server
Copy Wazza
LargeSystemCache
/MAXMEM or /BURNMEMORY
GUI Theme
Processor Affinity and Priority
Background Services
RAMDISK Applications

Yeah I have read that a while ago and picked out the best tweaks for me. I never tried the Waza thing though. :blink:

I've only used spitweaker for waza, but only for a couple runs. I have taken about 30 seconds off by finding the right pagefile for that particualar install. Now I just need to find my "range" to test with each install to find the best quickly.

Got a DL linky to this by a chance? :blush:

I will have to dig it up. I am on my phone right now. I had to dig a little to find a good d/l of version 1.6.
