New M6500 Discussion Thread

I've been having major issues with my FIPS fingerprint reader, up to where they decided to replace the motherboard .... long story ... anyway I requested the USB3 upgrade and it went in without a hitch. Unfortunately I do not yet own a USB3 device so haven't tested the ports

I am not sure if you can buy the part directly from Dell though, others have had more info on this in the past.

 

Hi all !!!

Great thread !!

Can some of you post some dpc test results on your beast as well as wprime ....

Dpc latency running while wifi disabled on the control panel , no battery , full performance power scheme !!

Please , please , please , i'm really struglling for those infos , need to buy my laptop asap , hp 8740W on my list , the 6500 is the best bang for the buck i can have for a fair price ....

thks to all

here's the dpc latency link :

The M6500 has additional power options available that are installed via the Dell System Manager. One of these power options is a Pro Audio Mode which shuts down some features to allow low latency for people who require this.

 

excellent .....so i think they heard about the dpc problems ....screenshots please about the value , i need no more than 150us ...under seven

 

Speaking of power options, over the past couple of weeks I've had two blue screens (7 64 Ultimate) attributable to power management drivers. Happens a minute or so after resuming from sleep it seems. Unfortunately, in both events, for some reason the crash report is attempted to be sent to MS before the wireless adapter has had a chance to come online apparently, so it fails.

Anyone else seeing this?

 

Follow-up: I took a chance and ordered an M6400 US-Layout keyboard (on eBay - they're cheap enough and in abundance). Whilst the bottom bracket is slightly different to the official M6500 keyboard, it does indeed fit - and works flawlessly.

Not sure if you'd be able to use an M6500 keyboard in an M6400 though; the missing 'tabs' on the locking mechanism of the M6500 keyboard would mean it might float around and not sit in place in an M6400.

 

dpc latencies pleaseeeeee ......

 

I turned on the "Pro Audio" power setting mode given that's what you'd probably want. Averaged around 200us, maxed out at 523us. Ran the test a few times to be sure.

FYI Got roughly the same results with "Maximum Performance" power settings too. Didn't seem to make any difference between the two power settings in the Dell System Manager.

Suggest you get a few more samples from others though, as it seems not all M6500's are created equal.

(M6500 Covet, Win7x64, i7 820QM, 8GB@1333, WiFi off)

 

Most of the time between 100 and 400, max after a few minutes 780.

Uups, shortly after reopening IE and starting to answer here I got a 6052.
Now it is back to normal again. And again while typing another red block around 6000.

 

not that good mmmm.....very surpising for a good laptop like that , nvidia card are known to make those bad things (due to their power optimization), wifi also ,

check this out on the alienware :

YouTube - Alienware (DELL) M17X Audio Stutter and DPC Latency

they got things right after the new bios release , have you guyz checked the bios version you got ? maybe dell have a bios revision also for the m6500
