Precision 7530 & Precision 7730 owner's thread

Last word? Hmm. You have consistently employed borderline personal attacks, and illogical statements, which are all founded on an emotional standpoint (referring to your first reply to my claim that the Dell had 'decent cooling', the former of which was rife with emotion, and what is called 'buyer's remorse'), to discredit my statement, while I have proven my points time and again, with data and statistics to back them up, which you have ignored, in your emotion.

If you want me to, I don't mind running other benchmarks that account for errors and such, to prove that an undervolt is not nearly as deleterious as you claim it is.

I also repeat my point that if you were so concerned about errors, you would've configured your notebook with either of the Xeons and ECC memory, which you haven't.

All of this leads me to believe that all you want is just a proper replacement notebook from Dell, which has denied you of the aftermarket service that you have paid for, which has caused you significant trouble, which in turn, is the reason for this extended debate.

I sincerely hope that your replacement is properly tested, and delivered soon, and perhaps you'll realise that things are not as gloomy as they are.

Have a great day.

 

I actually have a replacement system coming. So no, not emotional, actually, but since you can't seem to debate logically and with facts, you now turn to full-on personal attacks. That's how people know when you've won a debate these days, I guess.

Data and statistics? Please do quote those for me, since I've seen nothing from you other than one benchmark result from one sample that you have.

I'm sorry you feel that calling out your "facts" which were actually opinions hurt your feelings. That was never the intention, as I've also stated that many times.

You continue to say I claim that it's the end of the world with undervolts, yet I time-and-time again have stated that's not so. Here's Intel's warranty booklet for the 8700K: https://www.intel.com/content/dam/s...s/Limited_Warranty_8.5x11_for_Web_English.pdf

There are other languages available here: https://www.intel.com/content/www/us/en/support/articles/000005862/processors.html

Can't get any clearer than that. Oh, and it says exactly what I said.

Xeons and ECC memory are two totally different beasts. In fact, getting a Xeon and ECC to undervolt the CPU is one of the most ironic things I can think of.

I'll stay above-board and not dive into personal attacks, here, but it sure does seem like you're trying to back up your choice at all costs.

 

See, I never said that they hurt my feelings; I said that they were personal attacks. How I felt about them is irrelevant.

You asked me to perform the same benchmark without an undervolt; I did, and proved that under the workload conditions of the benchmark, the Dell Precision still cools the CPU sufficiently well that it performs within specification. I will be pleased to run other error-checking benchmarks (Prime95? OCCT? Intel Burn Test?) and show that under those conditions, too, the cooling performs within spec, too, and there are no errors thrown with the undervolt applied.

From my point of view, your rhetoric certainly seemed like it. I agree that Intel would not honour a warranty claim arising out of changing clocks or voltages—which is in itself strange, as the 8700K is advertised as being able to do precisely that.

It is also strange that you are quoting Intel warranties for a Dell notebook, as the warranty for the notebook is provided for by Dell. Third, it is highly unlikely that you would ever need to perform a warranty claim because of an undervolt. Intel itself knows how unlikely it is; if someone claims warranty because of voltage changes, it is likely because they have overvolted and overclocked to the point that transistors have catastrophically failed.

ECC memory does what it says: it corrects for errors. You may consider it ironic that I have a Xeon, and yet undervolted; I simply did what I do on all machines: undervolt to the maximum possible, such that I balance stability, thermal and computational performance.

Perhaps we'll just agree to disagree. You claim that this is a notebook targetted at businesses, and hence there should be no undervolting necessary; I claim that all modern hardware is more or less equal, regardless of use case and target consumer profile, because they are all mass-produced, and hence undervolting, which has been shown to produce a net positive effect on consumer machines, should produce an equally net positive effect on these business machines.

 

Finally got my Dell 18,000mAh PowerCompanion today and plugged it into my 7720 for just a minute or two.
Works fine, though the computer thinks it's plugged into an AC source, so you know nothing about the status of the portable battery AND, depending on your settings, the computer will not be in any kind of power savings mode - to make this external battery last longer you'll have to manually go into power savings mode.

Without the external battery I was routinely getting 4-5hrs (easily) with the internal battery doing MS word (big) docs, big PowerPoint docs, email, web surfing/downloading some big PDF files, etc. while on WiFi. Way better than my M6700.

The 7730 would have been great to have, but it's been really nice using my e-port plus.

See you over in the 7720 forum!

 

It doesn't complain about being an "underpowered adapter"?

 

That might have been me. I've been waiting for these before buying a 2TB NVMe SSD as the final upgrade for my Precision 5510. I also found (I'm in UK) this on Amazon which has the attraction of a well-ventilated enclosure (I've used the SATA adapters without the enclosure so the SSD gets more opportunity to cool and the faster NVMe will be hotter) . It's good to see that both JMicron and ASMedia have woken up to the need. Now to wait until the residual bugs get fixed. Meanwhile, prices of 2TB M.2 SSDs have shown a healthy downward trend.

I couldn't agree more.

@thetoad30 and @Ionising_Radiation, you are obviously not going to see eye to eye on this, so please lets move on. Either start a new thread, or continue this conversation via PM.

 

Hi @Ionising_Radiation and others experienced with undervolting on laptops, etc.

As I’m waiting for my new Dell 7530 I read through posts here and info on how to undervolt and tried it on my HP ZBook 15 G4 using Intel XTU. It’s currently at -120mV and it works really great, significantly cooler and no throttling ever.

Question: Is undervolted CPU stability a binary phenomenon, i.e. stable and everything good or unstable and definite BSOD? So nothing in between where there can be some strange things happen but the computer and OS still work?

 

If you undervolt your CPU too much, it will start to make mistakes. If it starts to make mistakes, you will know it right away. (BSOD or hard lock.) As long as you do some stress testing and push it to max load for a while, and it doesn't crash after an extended period of time, you are good.

 

WHEA correctable errors in the Event Viewer, which are non-crash errors, can also point to an unstable undervolt. A WHEA uncorrectable error is a BSOD.
