Re: XPS 730x H2C loses power / resets / reboots "randomly"...

  That is not cpu temp,its the temp inside the case. Correct? Its good to double check anyway dells thermal software could be way off.

 Run real temp 2.90 or coretemp to see if the cpu is overheating.

Re: XPS 730x H2C loses power / resets / reboots "randomly"...

 You can run prime95 too. Put a load on the cpu and see if it overheats. My core i7 build runs 41c at idle and 80c at full load using prime95 with the stock cooler. I bought a aftermarket cooler and my tems are 34c idle and 60c full load.

 These are cpu temps not case temps.

 Your computer should run stable at 85c under full load.

I installed and ran CoreTemp tonight and when playing "Far Cry 2" the highest temp I saw was 67 Celsius on one of the cores (I have the 730x H2C).  However, after about 15 minutes of playing the machine reset on me.  I am running at the overclocked 3.73 GHz.

Re: XPS 730x H2C loses power / resets / reboots "randomly"...

I decided to throw in the towel on this system.  No matter what I try (and I think I have tried just about everything over the last month) it will reset / reboot at random times.  So, after finally getting through to the Dell returns department, and then being on hold for 45 minutes, I was able to get my return setup.  The good news is Dell is refunding the entire purchase price and paying for shipping back to Texas (that was a big relief, thanks Dell).

I will continue to monitor this thread and I hope someone can figure out what is wrong with these systems.  I think the system is great other than this issue (of course) and I would buy it again if I knew this problem was fixed.

PS: The one thing I never tried was turning off Turbo Mode in the BIOS and just running at a 24 mulitiplier - 3.2 GHz (I did run it with the F9 defaults but that sets it up with 26,25,25,25 multipliers) .  I know everyone is probably thinking "what's the point in that since it is marketed / touted / and sold as being overclock-able?" but in my four weeks of experience with it the higher the overclocking the worse it got (I only went as high as the recommended 28 multiplier - 3.73 GHz).  I will have this system through the weekend so that I can clean off the hard drive and I will keep it at 24 (non - turbo) to see how it behaves.

 Try running prime95 if you get a chance. I would still like to see what temps are and if its stable under full load.This could narrow it down a little more.

Also you could try disableing stuff running in the background in taskmanager.

Re: XPS 730x H2C loses power / resets / reboots "randomly"...

Actually for me, I can disable everything it makes no difference. Sometimes it won't even get to the startup  screen. it'll just keep rebooting a few times over. Other times I can play Crysis for an hour with no problem. However, whenever I try to open a few apps that I use for work.. boom.  I don't think i'm really pushing the cpus at all. I'm just running apps a few apps that aren't cpu intensive.

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 I ran Core Temp along with Prime95 it two test runs where #1 was at the non-overclocked settings (3.2 GHz) and #2 at the recommended overclocked settings (3.73 GHz).  Both ran for about 18 minutes before I stopped the test and all tests passed (no resets or reboots either interestingly).  Here is what I saw as far as temperatures:


3.2 GHz - Maximum core temp = 72 degrees Celsius


3.73 GHz - Maximum core temp = 80 degrees Celsius

Re: XPS 730x H2C loses power / resets / reboots "randomly"...

Looks like the cpu is not overheating. Its still possable the video card could be.

Are you guys using a thumb drive or a usb device like magicjack?

 I had a problem like lovereason is talking about. Unpluging majick jack seamed to stop the endless reboot.
