XP + Super Pi help needed :(

post #1 of 4
Thread Starter 
I need some help with configuring XP SP2 x64 to get some better Super Pi 1M times. I currently have XP stripped pretty bare (nLite'd and manually tweaked), but I get worse 1M times than my daily Windows 7 OS!

What you can't tell from my screenshot: It's a fresh XP Pro SP2 64bit install. In addition to the obvious stuff, I have DEP and the Pagefile disabled, Super Pi's affinity set to one core, and it's all on a properly-aligned SSD.



Can any of you gurus see something I don't? For reference, I pulled 9.922s for 1M and 8m 54.382s for 32M in Windows 7 64bit.

Thanks!

If you turn off HT to get more overclock that will help, with 4 cores run it on each one, one will usually be a bit stronger than the others (all my i7s core 2 is strongest).
You don't have a memory tab open in the screenie, overclocking the uncore as much as you can will help.
Also, win xp 32 bit has always been best to me for superpi.

Thanks for the tips, didn't know about certain cores being stronger.

I should add, however, that I just chose 4.1ghz arbitrarily. When I do it for real, i'm hoping for a 5ghz run on water (current best is 8.3s at 4.9ghz in windows 7). I know about the mem and hyperthreading .

My issue is, clock-for-clock, a bloated windows 7 install pulls faster 1M times than a stripped-down XP . I also tried XP SP3 32bit, and it was even worse than 64bit XP. I was hoping I accidentally disabled a service I shouldn't have or something.

Bump on this.

All of the guys on XS are using XP and I'm trying to get a nice stripped OS.
