Not sure if my probem is directly related. I have a 1557 Core i7 with BIOS version A04 running Windows 7 x64 Ultimate with all latest updates and drivers installed and a 90W power suply

My laptop initially runs fine with SpeedStep enabled, then after some hours it starts slowing down until it becomes unworkable and slows down to a crawl. The Intel ProcID utility then reports clocks speeds as low as 0.07  Ghz (1.6 Ghz expected). Eventually Windows (7 x64) crashes with a 0x101 bug check which means that a clock interrupt was not received within a reasonable time interval.

When I disable SpeedStep in the CMOS setup, things work fine but my CPUs run only at 0.93 Ghz. Note that this is definitely NOT a software issue, I believe this to be a thermal issue. Rebooting the system is not possible (it crashes during the boot phase) until the box has cooled down. Another problem is that CMOS data is often reset to default configuration so the problem pops up again when SpeedStep is back to enabled again.

Are there any known solutions or should I send my box for warranty repair ?

Thanks,

Daniel

I got this box on march 15th, it was working great until I updated the bios that's when the freezing started randomly on wake up, I think I was running A06 and was looking for A07 but could only find A08, but again no problem until the bios change , hope this can help

I just updated to bios A05 which came out yesterday. The behavior changed somewhat, with Speedstep enabled it does not slow down infinitely but goes back to a corespeed of 798MHz and stays there forever. So I can choose between a clock speed of either 798Mhz (with SpeedStep) or 933MHz (without speedstep) which are both not acceptable. I am going to send back my box to Dell. Also still the CMOS data still resets itself on reboot which is very annoying, in particular the default setting of "Multimedia Key First" which is further proof of a boneheaded design.

My problem is with a Studio 1749 which freezes. A quick fix is to unplug the power adaptor and replace.

It looks as if CPU load has gone over a certain maximum, it scales back and there is no way to get speedstep to work again. But I admit that since I have set the minimum processor state in advanced power management to a lower value I am getting better results now. I changed my mind and am going to give this some more time and live with a few problems which hopefully get fixed with another BIOS update in the future.

Todd or anybody that can answer, are these Issues still being addressed by Dell ?  I have not seen to many post or changes in drivers, bios or software. I am still having usb power problems but I was wondering if I was wasting my tim following these forums.

[quote user="dmblack"] Early February XPS 1645 arrived. Zero problems- until trying to run streaming video in full screen mode from sites like Hulu, Youtube etc. Did a new install of Win 7 and same results. No problems until running streaming video in full screen mode. - Studio XPS 1645 -ATI Mobility Radeon HD 4670- driver 8.632.1.2000 -BIOS A08 -90 Watt/ 130 has been ordered -Adobe flash 10.0.45.2 -Motherboard OY517R Putting a clean install of Win7 made no difference when viewing streaming video in full screen mode. Simply cannot get through a full screen video without one of these results---The screen going grey with sound continuing to play followed by lock up. Screen breaking into pixels followed by lock up. I see some suggestions I have yet to try, but for now I'll just put my experiences out and hope it helps.

Update.

130W power supply in use.

Installed all Dell drivers per Dell's priority installation method, including new ATI revision over the clean install of Win 7.

Happy to say that the lockups during full screen streaming video are absent, that with 120 minutes of consecutive use.

No other lockups or odd behaviour.

Hope that's all for me. If something report worthy comes up I'll be back with details.

Update.

After roughly 50 hours of live streaming video - MLB.com- YouTube-  Hulu etc. not one lock up.

This 1645 is working as it should :>

Hi,

My Studio XPS 1647 is having random freezes for the past several days; it started after I updated my BIOS driver to the latest A06 as well as the sound driver. The computer just freezes randomly (not heavily underload) and keyboard + mouse both unresponsive (hard drive indicator light sometime flashes, other times stays lit). I waited for hours and the computer still did not come back so I had to hold on to the power button to turn my computer off. I've had 5 of these already over the past three days, and I have my 130W adapter plugged in when I was using my computer.

Can anyone help me please?

Thanx in advance.

"Installed all Dell drivers per Dell's priority installation method, including new ATI revision over the clean install of Win 7.  After roughly 50 hours of live streaming video, not one lock up".

dmblack,  Could you please elaborate a bit on your ATI revision?  For example, what driver version & how did you obtain it?  Did you do the whole Catalyst Control Center thing? (There’s a new version 10.4 on their web site).

My computer is a Studio 1747, A08,  i7, 8 GB, 2 x 500 GB hd, 1920 x 1080 w/ATI Mobility Radeon 4650, Win 7 Ultimate x 64, 130 watt.

My original problem: random freeze ~ 3 per day (display normal, but no response to keyboard or mouse); cured by replacement boot drive w/ new Win 7 image; NO freezes since for 1.5 months.

New problem (hadn't tried before): Bizarre video behavior with full screen streaming video, including one BSOD saying "video driver stopped responding".  Seems better with no other windows open, and/or with ATI PowerPlay turned off.

Sure :>  After clean install of Win7, only the generic windows drivers were running, so I didn't need to uninstall the old ATI software, avoiding a pita that some people have reported.

Yes, I installed the whole ATI Catalyst Suite for Windows 7 (64 bit), not 10.4, but the prior version.

ATI driver 8.632.1.2000.

Hope that was helpful-

Thanks dmblack; yes, your feedback was helpful.  My Mobility Radeon driver appears to be even newer (8.650.0.0).  On the principal of "don't fix it if it ain't broke", I believe I'll leave it alone at least until I hear positive feedback re: Catalyst 10.4, etc.  Streaming full screen video isn't something I normally do, but when I heard of the problems I "had" to try it, and got my bad, though inconsistent, results.

Posted as a comment on my video of the lockups :

BATFURY ive got the same laptop:
core I7
win 7
ATI HD 4650 1go
My laptop is crashing exactly like in the video like 2 time a week or more...pretty annoying when youre doing homeworks while watching videos because i must force reboot.

it often crash when i put online videos in fullscreen and it just crashed after 10 min of listening of a 1080p movie i was watching with vlc in .mkv fromat.

as anyone found the solution to that problem?

Dell ? Todd ? Bill ? anyone ? After having divided the thread of the complaints, do you watch this one ? Do you still care ? what about the engineers ? After having send them all the informations that we have sent, do we get the right to get ANY feedback ?

Constant screen freezes.

At first I thought this might be programs overwriting video memory.  Don't know.  Worried about HD after restarting literally a hundred or more times via switch.

Have you guys found anything at all?

Thanks

Frank

Thank you my friend.

These have been done. 

Will let you know.

Frank

It did not freeze during download or install which at this point is good.
