Re: Studio 1737 DPC Latency

 

 

 

Hi... i'm a studio 1735 user.. and i also have these spikes every 5seconds or so.

i have been resea...

This is the problem and solution for the Alienware M17x Systems

» Summary

Article Summary: This article provides information about what to do if you experience high Delayed Procedure Call (DPC) latency on your Alienware M17x system.

Back to Top

» Description

If your system has high DPC latency, this issue may cause audio or video stutter when playing video games or playing audio or video.

Back to Top

» Solution

  1. Update the system BIOS to the latest M17x BIOS A03 (R254103.exe), which reduces the CPU thermal polling that was causing most of the high DPC latency problems.
  2. Verify that you are using the latest Broadcom wireless driver found on the Dell Support website. This driver corrects latency issues encountered with the native wireless driver included in the operating system.

 

so from that.............. i am wondering if CPU THERMAL POLLING is the culprit for the DPC issues on our studio systems too.

Are the engineers still working on the problem?

Re: Studio 1737 DPC Latency

I have a nearly new Inspiron 1750 which has the same latency problem, I have the updated A06 bios, but it still happens.

The laptop came with Windows 7 x64 installed (I created a dualboot with a music partition), and a Broadcom WLan chipset. Is there any improvement with this model ?

Re: Studio 1737 DPC Latency

Does anyone know if this latency problem  has been fixed yet as I have a studio 1735 which is useless to me as a tool for audio creation due toit.

I would be prepared to upgrade to the 1749 (I guess that is the latest ) with touch screen  if the audio stuttering is fixed.

Does anyone know if this is the case as I don't want to waste another couple of grand almost.

Thanks

Re: Studio 1737 DPC Latency

I'm having the same DPC latency issues.

I have a Studio 1555 with the following specs:

Studio 1555 : Intel Core 2 Duo Processor P8600(2.40GHz, 1066MHz, 3MB)
4 GB 800 MHz DDR2 Internal Memory
500 GB SERIAL ATA (5400RPM) Hard Disk
512 MB ATI MOBILITY RADEON HD4570
Intel Wireless Card Label - Core 2 Duo
Intel WiFi Link 5100 (802.11 a/b/g/n 1X2) 1/2 MiniCard European
Europe Dell Bluetooth 370 Card
Windows 7 Home Premium 64-bit

The model number is PP39L

See below my DPC Latency chart:


Like most people here I want to use my Studio 15 to run Traktor Scratch Pro. The latency tests however are based on stand-alone performance by the Studio 15, no additional devices were connected to the laptop.

I recently installed the newest version of the BIOS for the 1555 (A11 released 14-4-2010) but to no avail, the DPC latency issues remain.

I was surprised to find that the Studio series of all Dell laptops have audio issues, since they are advertised as multimedia savvy laptops. As I have been reading a lot the last couple of days around the internet it baffles me that Dell to this day has not come forward with a solution to these persistent problems a vast number of its customers is experiencing. As mentioned on numerous occasions it's hard to swallow for Dell customers that their laptop is not delivering on one of its key selling points: multimedia experience.

I hope the Dell team could give me and all others some support how to finally tackle this nagging issue once and for all so we can finally enjoy our Dell laptops to their full potential. I was very satisfied with my laptop until now, but then I faced this latency issue when I started to use it with Traktor Scratch Pro.

Re: Studio 1737 DPC Latency

My 1737 is working fine with the ACPI workaround but I'm sick of having to do it now.

We need a fix to this problem Dell!

 

Was that with a XP 32 install ?

I tried suspending both ACPI threads in W7 64, but it made no difference

Re: Studio 1737 DPC Latency

Yeah, I'm using a W7 64 and suspending ACPI makes very little difference. I wish Dell could do something about this. I've bought 2 Dell Laptops since 2007. This will definitely be my last. I'm currently saving to get a new system. My sister is about to get a new computer, and I'm going to have to steer her clear of Dell. So sad...
