Show Us Your WEI

[Windows 7]

Here are my ratings on Windows 7 Beta 1.

 

[garysgold]

Here's mine from build 7000.



Processor and RAM are up from Vista. The rest are the same.

Here's my lame score.

I don't get it - why am I and others with obviously fast drives (Seagate 500GB 7200.11 drives - IOW, 32 MB Cache) showing such a *noticeable* dip in performance?

Is it because I (and others) did not create a partition and let 7000 use the entire drive?

 

[darkassain]

yes john most likely thats what it.....
as i see it....
if you didnt give it at least a good portion of your space i do see the wei going down....

man W7 has been getting greedy for space recently...lol

 

[johngalt]

Umm I gave it *all* the space....

As in I deleted all partitions on the drive and then let the installation proceed.

 

[darkassain]

weird...
Very weird indeed....
was this during before or after the installation???
(most likely after....)

thats really weird...

John,

Have you installed the motherboard chipset drivers? You may need to use compatibily mode to do so, but it may help.

During Install - it would hang when it was getting set to do the final reboot, and if I forced it (even after waiting 2 hours the first time) W7 gave me an error and asked for me to boot from the DVD and restart my install.

Weird, since Vista never once coughed at my OC - then again, I did have my OC toned down a bit, to 3.21 GHz instead of 3.375, that may also have been a factor....

John,

Yeah, I did that - no change.

But, I figured it out. Thanks to this post http://www.sevenforums.com/general-discussion/1088-7000-leak-14.html#post9814 I found the answer - and I haven't even applied Dave's tweak yet.

Many of us, especially OCers, tend to disable Native Command Queuing in the BIOS - however, I just found out that W7 has it enabled as an option for our SATA controllers. Whether this is from the nVidia drivers or native, I don't know - I suspect native because of the dramatic results I am about to show you:

My original Build 7000 WEI:



So, seeing Dave's post made me think - perhaps there is another tweak. Sure enough, take a look at your SATA controllers in Device Manager. See the following window captur and the attached Speed Test:



Now, if you uncheck Command Queuing, initially nothing happens if you run a speed test - because a reboot is required. However, notice the *dramatic* speed changes after removing Command Queuing and the requisite reboot:



I say that the drop in sustained speed is negligible compared to the *massive* increase in the burst speed - and, as I suspected, the WEI is based more on burst than sustained....

And, finally, my new WEI:



Again, this is without Dave's tweak - I am going to see if that makes a difference or not - I suspect I'll be back in the 6.9 range with it also performed.

Enjoy, Folks!

 

[darkassain]

nice tweak john...

ill see if i can apply it to mine...

 

[johngalt]

Note: On my system, after applying the Command Queuing tweak, I had no effect from applying it to any other port where enabled, so I suspect that WEI only tests a single disk.

Also, I had no effect whatsoever from removing the Write Caching from the drives either - however, the WEI test itself took over twice as long to complete. Therefore, I suspect caching is not taken into account in the WEI.

(Sorry, Dave)

 

[Brink]

Well John,

It looks like I do not even have that option for my SATA controller.

 

[johngalt]

Nope - NCQ is not available through Intel Chipsets IIRC.

check all your other HD related devices, though, there may be something similar....

Also, you may want to check your mobo's BIOS and see if it is on, if it *is* supported by Intel....

And while you're at it, check for an updated BIOS for your board....

 

[johngalt]

That could be it as well - but Shawn's board is a little over 3 months older than mine, IIRC - I remember reading through the thread over at Vx64 when he decided to build the new comp - according to his system specs, he has

Motherboard Gigabyte X48-DQ6

So that should not be an issue, unless it is simply not ...

Oh, wait. I also installed the nVidia chipset drivers for my mobo - and *that* might be why *I* have the Command Queuing in my SATA controller properties....

 

[darkassain]

intel wont let you install the drivers
the setup will refuse to install on mine...
saying its an unsupported system

 

[johngalt]

That may be it then. Since nVidia is already working so closely with M$ they may have advanced features.

Now, I am curious - I want to know if this is a direct result of my chipset drivers install or if it is built in to W7 based upon the chipset detected when booting....

Anyone out there with nVidia chipsets, preferably nForce 7 (750/780/790) based machines that have not installed the nVidia Chipset drivers? If so, can you confirm if you still have the Command Queuing option available?

 

[Mark]

Well I have one but I have installed the drivers and the option is available, I just tried to disable it to see if it made a difference and it showed improved performance in the speed test but that had no effect on my WEI.

 

[johngalt]

You're WEI was already high - which means that for some reason my WEI was measuring burst speeds not sustained, or else there is some other weird and cooky concoction of combination of parameters that I am not 100% aware of causing this massive fluctuation in WEIs.

 

[Mark]

I checked it on Vista as well and that too has this option and when disabled has the same effect, so it is more something to do with nvidia than anything else.

 

[johngalt]

That is what I thought - I honestly did not remember seeing anything about Command Queuing until I started OCing - then it popped up everywhere.

Since Dave said to try the HD trick, I was gonna do that, but then thought that there must be something else - cause *disabling* write caching should not affect my performance for the *better*, in fact, it should be quite the opposite.

That is when I stumbled upon the Command Queuing setting in the SATA controller - and having read over and over about disabling NCQ when OCing on nForce based boards, I experimented - with the appropriate screen shots - and got extremely lucky.

But what is weird is that you have a 750 and I have a 780 - perhaps it is because of the drives you have? I am using a pair of Seagate 500GB 7200.11 (32MB Cache) HDs, and for the SATA controller connected to those 2 I could enable or disable CQ - bu for my 3rd drive, a WD 250 GB 16 MB Cache HD, the option is grayed out.

I am going out on a limb and venture that you either have Samsung HDs or Seagate HDs without the large large cache....
