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

I asked reg549 if he ran "Dell Thermo Monitor" program after his fix and Dell removed the post! So this may be my last post since they threaten to remove me from posting on the forum. I simply asked if he ran the program one simple sentence and Dell felt it was offensive. What good is a forum if it going to be sensored! Good luck folks, I'm done with these guys for good! BYE BYE

I uninstalled the Thermo program, and it still reboots, wouldn't blame the program for something hardware related.

I've also changed the bios from 120 to 140, also did it to 80 after I first got that number from Dell. On the first change to 80 it ran stable for 3 days then it rebooted on me again.

After the change to 140 it lasted about 4 hours before a reboot happened again.

No use updating the bios since there's only 1 version available on the site.

Running out of ideas

I agree with you that it's a hardward problem, but the Thermo Program is the key to this whole thing. Whatever hardware is failing the Thermo Program  hits it everytime! This program will fail the computer consistantly, see what the software is doing and find the problem to the hardware. The Classic hardware vs. software issue! My option anyway...GOODLUCK! (Still haven't got my refund!)

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

Hi. I've never posted here before Richsi, but I have my 2nd XPS 730 x and another scheduled tech to replace the motherboard, processor and heat sinks on this new on once again. Since we have purchased a separate i7 965 processor and memory, we decided to try a few things in an attempt to isolate the issue. We changed some settings in the CMOS and i recall (this happened a few nights back, say 5? not sure) correctly, on of them was the setting that allows the i7 core processor to dump cores, or slow down, not sure what the correct term is. Now this system is been running for 4 days...NON-STOP at 4GHz without rebooting, withou BSOD, and without any issues temp wise.

I have to reboot the machine (this is the one i'm using to type this) to write down the settings and post them here, but also, we removed the XMP option for the memory speed. Memory Volt I know for a fact is 1.5v and it is the 8500 dell ships. We have the TR3X6G1600C8D memory and has been replaced 3 times by corsair, thinking the memory was faulty, but the problem appears to be, and mind you this is for the BSOD with a memory page fault error, the problem seem to be the memory voltage or XMP option. Since the Samsung memory that dell ships does not have the Extreme Memory Profile, I guess it is not an issue, but with the corsair we were getting all kinds of BSOD all with a memory page fault with default voltages, with 1.5v and also with 1.65v which the memory is design to run at.

Now i dont know if this helps any of you, but we're running this thing a 4GHz non-stop and so far not one reboot. We've ran Spiderman Web of Shadows, Crysis with max settings (little sluggish), warhammer, dead space (which doesnt require much power, but still), we've ran MS Flight simulator x with a 6 hour flight and many more games. I'm a heavy gamer, and I hated it when it used to shut down and restart.

I can send you the settings or post them here. I'm not sure how to find this post again, but i'll try.

So the cooling issue is NOT the issue in my case, and this thing came from Texas. I think the setting to bring the cores back down is the problem, yet again, i'm not sure, but it surely works on mine...!!!

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

Hello, I recently posted another post, earlier today. I'm new to this and I am no expert. I've received my 2nd XPS 730x this month and this one is scheduled to get mobo and processor along with heat sinks replaced AGAIN, due to the same shutdown w/o warning problem. Since we have a 2nd processor we purchased a while back, we decided to try and play with the settings a little. I have been running this XPS 730x at 4GHz non-stop for 5 days REALLY NON-STOP, without any power loss, any BSOD or anything other issue. We ran Sandra and ran a burn in test for 12 hours, no power downs, no heat problems, no NOTHING. These are the settings we have on this machine (images below), and these are images of the settings. Use them at your own risk, like I said, our machine has NOT done a re-start or any other problems. The problem IN OUR MACHINE ONLY, not talking about anybody elses, just our XPS 730x with i7 965 EX, with 6GB Samsung mem, our problem was the c-state setting, this i guess, allows the processor to rest, or shutdown, or slow down. I'm not sure what term, but this setting was turned off, and after that, we can change anything on the overclocking or overvoltage and OUR MACHINE does NOT reboot, not once, not anytime. Try it, and if it works for you, pass it along. I'm tired of Dells inability to resolve our issue, and simply saying "oh, we'll send you another one" or "Oh, we'll replace the processor, motherboard, heat sinks, cooling system". So, we must do something ourselfs until they come up with the solution. Here are the pictures of our CMOS. YOU MUST HAVE LIQUID COOLING FOR THESE SETTINGS, IF YOU HAVE AIR COOLING, THE correct settings for your VCore Offset must not exceed 80mv, and your core cpu turbo ratio limits should not exceed 26 with a TDP value of 180 and TDC of 160. Anything outside this values is at your own risk.

Start with this, for those who have the stock O/C settings, change the values according to Dell's recommended. The settings above will o/c your machine to a steady 4GHz, with no sutdown, reboots or BSOD of any kind with temps of (see Dell Thermal App image below) Idle, and 53, 54, 56, 51 Loaded. Also, please be advised that your processor WILL NOT clock down once you change the cstate setting to disabled. If you get a steady working mahcine, try re-enabling your cstate setting, BOOM, your machine will reboot AGAIN. IF YOU HAVE CORSAIR MEMORY WITH XMP ENABLED, YOU MUST DISABLE IT OR YOU WILL GET A MEMORY PAGE FAULT UNLESS YOU ARE RUNNING THE VOLTAGE @ 1.65v for the memory. And this doesn't always work, the XMP for some reason is really tricky, and can be quite annoying with it's memory page fault.

Like i said, i'm no expert and I know nothing about overclocking, much less about dell machines, but these are the settings that WORKED FOR US. I SUGGEST YOU NOT USE THE BELOW SETTINGS AND LET DELL HANDLE IT, BUT IF YOU WANT TO ENJOY THE SPEED AND POWER OF THIS THING, THEN TRY THESE SETTINGS UNTIL DELL DECIDES WHAT TO DO, THIS MACHINE HAS A LOT OF POTENTIAL, A LOT OF POWER, BUT DELL MUST FIX THIS ISSUE, OR THEY ARE PUSHING PEOPLE LIKE US TO FIND ALTERNATE SOLUTIONS. These processor overclock with easy, giving you extreme power with minimal heat problem, but you must test first, DO NOT DISABLE YOUR DELL THERMAL MONITOR PLEASE, THIS LITTLE APPICATION DOES WORK AND IT DOES GIVES YOU CONTROL OF YOUR PCI CAGE FAN, REAR PROC FAN, HDD FAN WHICH YOU CAN INCREASE IF YOU DO SOME O/C. WE KEPT THESE FANS AT MAX WHILE WE CONDUCTED OUR TEST, JUST TO ENSURE THERE WAS LOTS OF AIR GOING INSIDE THIS THING. IT GETS HOT. If you have SLI enabled, I recommend disabling it until you get a steady OC working to minimize heat created by these two video cards, if they are 280's, they WILL generate LOTS OF HEAT. Get EVGA precision and crank up those fans to about 70% until you stabilize your system.

 Now, these are exceeding recommended levels, but if you enter the default Dell O/C settings, they will work, so long as you dont have the XMP enabled and the C-State Tech must be DISABLED.

If this works for you, please pass it along to another XPS 730x user who's frustrated because they can't enjoy their $5800+ investment, so they can at least enjoy a game or two with this machines incredible power.

 

DISABLE XMP FOR YOUR MEMORY, DISABLE C-STATE

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

Hello all,

I was planning to spend over $6400.00 for the XPS 730X on Monday.

I am really glad I found this forum, which I came accross through google. I most certainly will not be buying it now. I read all the pages on this topic & am sure glad I did.

I previously bought 2 dell systems. Not many issues with them. Would be afraid to buy the XPS 730X now.

Can anyone suggest any other reputable online companies to buy from. Preferably a company with support.

Thanks

Rick

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

Thanks  Ebaul for your Help.

I tried what U said but have some problem.

My system start...allo OK. Than i try to render something with maxwellrender and after some time my PC give me a BLUE screen with a dumping memory error and reboot.

My brand of memory is ELPIDA DDR3 SDRAM (6 gb). any solution? Maybe 1.55V is not good for this kind of memory.. may I have to swithc to 1.65V ? I cannot find in the DELL BIOS the option to DISABLE this XMP function. how can i disable?

 When I found this forum, I was actually searching for the motherboard used in the XPS 730X. It was no where to be found. I do not understand why Dell is so closed mouthed about the motherboard they use. Other companys tell you what motherboard they use & some even give you the option to purchase. The only reasons I could see Dell not telling me which board they used, was, it was either a low end board, or, they do not stick with  any one brand of board when they put the 730x together. Being so closed mouth about such an important part of the computer, would get anyone thinking in a negative direction. I should have the right to know what I was going to purchase.

Thank you so much Richsi. I really appreciate your response!

Have a great week!
