XPS 730x General Hardware Discussion thread

You'll want to rely on a source other than Dell for ideal or expected operating temperatures.

Actually, if you're smart, you'll check other sources before relying on Dell for anything pertaining to your PC even though it was manufactured by Dell.  The reason being, the Dell tech support hotline rarely has a clue of what they're talking about and will steer you wrong 95% of the time.

I could've told you that you were in the danger zone with your CPU, considering 100C is the threshold.

Um, Dell may tell you that your temperatures are fine regardless of what they actually are. When I received my unit (I7-940 liquid cooled) these were my temps under load: Temperature sensor 0    98°C (208°F) [0x2] (Core #0) Temperature sensor 1    87°C (188°F) [0xD] (Core #1) Temperature sensor 2    100°C (212°F) [0x0] (Core #2) Temperature sensor 3    79°C (174°F) [0x15] (Core #3) Dell said this was just fine. My system has been running well with virtually zero problems since (other than the LED lighting has never worked correctly).

Wow those are way off base.  I have spent countless hours researching this issue on what safe temps are.  I have looked at most of the overclocking sites and have seen a variety of answers.  My temps seem to be in check.  I would be curious at what temps your seeing now in Prime and under "normal" load and at idle.  It was interesting to me that when Phenom installed his H2C, his temps were simlar to mine.  I think he has a cooler room overall from what I gather in his posts.

For me the bottom line is this.  Is the Dell H2C system the best in the whole world?  No.  Is it the worst?  No.  It serves its function and for me at least the temps are in the safe range for everything I do.  When I look at systems on other overclocking boards they all have different set-ups.  As for the C-state option in bios, my understanding per a previous poster is that could reduce your temps by as much as 3-4c.    I am not sure if these other home built systems have this enabled or disabled.  I think I will try it for kicks.

I certainly agree that it is good to look to other places for information.  I am sure I have seen some of your posts.  :emotion-1:. 

Right now, with my Core i7 920 overclocked to 3.20ghz, my idle temp is 37c-38c with C-State Tech enabled and my room temperature is around 73F.  Load temps are 65c.

I'm sure if you had read my post you would have helped out.

No prob man.  I'll be here if there's a next time.  :emotion-5:

Ph3n0m,

As you know I had my 920 OC to 3.67Ghz with your help. A couple of days ago, I turned my PC off for the weekend and when I turned it back on, my PC would display that my OC settings were causing issues (written in red during POST). In your instuctions, you have Cstate disabled, but your current post you have C-State enabled. Which one should I be using?

Is there anyway you can post your current OC settings?

Thank you in advace,

Joe

FYI.. My H2C system 2.67Ghz at idle temp is 35c-38c.

In your instuctions, you have Cstate disabled, but your current post you have C-State enabled. Which one should I be using?

     I enabled C-State Tech to see how my PC would react and it's running just fine, other than running 3-4C lower.  C-State Tech is part of the thermal control for the Core i7, which is why I enabled it.

My current OC settings are as follows:

BClk - 160

CPU Multiplier - 20

RAM voltage - Auto

XMP - Disabled

Speedstep - Enabled

TurboTech - Enabled

I/O voltage - 1.10

     Everything else I have set at default and it's running like a charm.  Why did I lower my clock from 3.67ghz to 3.2ghz?  Because I didn't need to run it at 3.67ghz except for the sake of running a benchmark.  I can't tell any difference in performance from 3.2ghz to 3.67ghz and it runs just as efficient while generating less heat.

My temp right now is 36c-39c, and my temp while gaming hits 43-47c.

For what its worth I have c-state enabled for a couple of days now and have had no issues (knock on wood).  I also see temps about 3-4C lower.

Need advice please. Lighting came in though the cable system and melted the modem wires. Dell 730x dead. Light in front comes on and that’s it. Insurance company said call Dell and get it fixed. After an hour on Phone was told they do not fix out of warranty claims. Phone number I used was 800-288-4410. The insurance adjuster came over (the computer is only part of the problem house damaged) and he said. "Just buy a new one and I can save the3 month old 730x for spare parts. So anyways I am going to buy a new one but like to fix the other one too. (Duel 730x towers side by side sound good to me. LOL). My questions> Can I take it any computer shop to have it Diagnosed.... Can I and do I have to buy parts from Dell so they fit... Do they sell parts to the Public? I logged on to the Dell Web site and found a place where for as LOW AS 49.99 they will have Dell tech check and send over a 3rd party for the actual repair. Would it be worth fixing? What could be the parts I need?

I sure appreciate any help from you guys. Thanks Bill

I have enabled the C-State, and also see temp drops by 3-4degC. No shutdown etc. On BIOS 1.0.3 with OC

That's awesome!  Hopefully other users will see this thread and discover the same thing.

Oh, and I created a group on Facebook for the Dell XPS 730 & 730x users.  I encourage you all to sign up so we can track each others progress with modding, overclocking, etc.

Well, I've also re-enabled C-State Tech, and so far through 4-5 days, no random reboots!

Looks like 1.0.3 finally solves the random rebooting problem.    Just remember to re-enable C-State Tech if the BIOS has it disabled.   The1.0.3  BIOS revision won't automatically do it by itself....you have to manually enable it again.

I also have had C-State enabled for a few days and no random reboot.

My 920 is OC to 3.2Ghz with 38-40c temps.

I have a 965 H2C system so not sure if others are noticing a similar activity.

Yes, my 920 does the same thing and you are correct, it's lowering the power/clock of the CPU when it isn't needed and increasing it when it does.  This saves power and generates less heat.

Just a curiousity question for those that enabled C-state.  I noticed the other day when I was running CPU-ID that is always listed the processor as running in OC mode at 3.74.  During the course of several reboots it showed the same information.  Prior to changing c-state to on it would fluctuate.  Not sure if this is an issue with the program or if C-state does something to change the speed of the processor.  If anything I thought it was in part intended to help underclock the processor when power was not needed.  I didn't change anything else in the bios except for c-state.

I need to play around with the setting.  I didn't try disabling c-date again to see if things changed.  Regardless it is not negatively impacting things from what I can tell.  No problems with reboots and temps are still lower.

I have the 965 air-cooled version, and with C-State enabled, the Multipier & Clock Speed constantly varies from Multiplier X12 to X26.

So far, after 6 days, no random rebooting.   This BIOS 1.0.3 version is the REAL DEAL.   Still too slow on the Dell BIOS screen after booting/rebooting, but everything else is just gravy.
