Windows 7 VS Windows XP, both 32 bit

[dishwara]

I have quad core, 4 GB RAM with Sapphire HD6870 1GB for mining. & 2 hard disks. one is 500GB & other is 80GB.
Usually i use win 7 for everyday life & mostly i will be installing & uninstalling any new softwares i see. & its always crowded with softwares.

Only 3 days ago i got HD6870 & before i had 9400GT.
i am getting 210Mhash/s at 900 clk (default) & 230Mhash/s at 999 clk OC.
If i go over 1010+ system crashes & at 1005 i got white pixels..
Having ati catalyst 11.2 & also SDK 2.3.

Today suddenly i wondered since win 7 using more graphics ....for visual appeal, what if i try in xp, will i get more hash/s.
So, i uninstalled all the nvida drivers & installed 11.2 & SDK 2.3 of xp.

When i ran the same poclbm in win xp, it makes background things slow.
when mining, everything takes time to open....system becomes slow.

Some one used/using xp getting better than win 7 or same or less.
Please any advices welcome.

Instead of going down to XP, you could try turning off Aero.

XP wasn't really done with gpu computing in mind. You could try setting -f 120 in the miner to improve responsiveness, but it's better to just use windows 7 or linux.

all i know is that aero doesn't affect performance on my 6870

I think everyone misunderstanding what i say.

With aero effects turned on & many softwares running in background, mining doesn't affect other programs in WINDOWS 7
The problem is only on xp. I think xp don't have aero effect.

what niooron said maybe correct, xp may not have designed with gpu computing
