Show Us Your WEI

I thought i share my wei, as i played around with drivers. I'm running 7201 x64 on a Macbook pro, 2.93 GHZ, 4Gb RAM..(and OCZ SSD Apex drive - they are amzingly different to even a fast SATA drive, in my exprience)


1/ With standard ms NVidia driver & display link USB software (top left)

2/ Now with no display link USB software, but 185.85 NVidia driver..big improvement (top right)

3/With 185 nvidia driver and display link usb..... (the USB display driver doesn’t impact performance) (bottom left)

4/And finally with write back enabled on hard drive...(another big jump!!) (bottom right)

so in essence the latest GPU drivers/enabling write caching boost perfomance a lot

Welcome to the forums Funkyfresh.

That sounds like quite a machine.
Can you explain this "write back enabling" or is it Mac only?>

Best wishes, John

My graphics card is letting mine down

So do I, I think it is time for new graphics card aswell,

Hi John,

Thanks for the welcome, I'm looking fwd to posting some interesting snippets I have picked up along the way...

Anyway, my system is quite fast - for a laptop anyway, and i like to see how it can be tweaked within reason..

When i talk about write cache enabling, the Microsoft terminology is "turn off Windows write-cache buffer flushing" –(select properties of your main hard drive in device manager, then policies)
.
By ticking the box, you are effectively allowing Windows to hold data in a buffer before writing to disk. This is fine with either a battery backed up RAID controller, or on laptops that have batteries – as if there is a power failure, the data doesn’t get lost, it will get written to disk. On a laptop this is because Windows will continue to run without AC power (i.e. on its battery)

On RAID controllers with a battery backup (typically servers or high end workstations), they will flush their battery backed up RAM buffer to the hard drive when AC power is resumed – ie during the next start up..
[if you ever watch Dell servers boot after a power failure, after the RAID bios starts, there will be a message about it flushing its buffers ...]

Hope that makes sense?

Quick question about graphics.

My WEI shows a score of 3.6, this is due to the Desktop performance for aero, but the gaming score is 5.1.

Why such a difference?

Just curious really as i dont game and the desktop seems to be fine.

cheers
