Precision 7530 & Precision 7730 owner's thread

Just because the likelihood of messing up the laptop is low, if something did break while repasting, then Dell can and most likely will void the warranty. Please don't advise people to lie in efforts to cover up their mistakes. Just like if you do the shunt mod and break it, dell can and hopefully will void your warranty.

 

Here you go:

I got my information from my own P7530. I live in a tropical country where ambient temperatures hardly, if ever, drop below 30°C. I don't experience throttling; I posted Cinebench results a while ago, and there is solid proof that the thermal solution in the P7530 outperforms nearly every other 15" BGA notebook out there, as it attains an average score of 1250 CB points over an extended, repeated run of Cinebench R15. I posted another run further back with a less aggressive undervolt, and it still achieves an average score of 1200. Either way, the scores are at least 20% greater than the ~1000 or so points achieved by many notebooks with the 8750H. Temperatures during that run hovered at around 79–83 °C, drawing 60 W of power, at 3.9 GHz, with a 120 mV undervolt. No other hardware changes. And this is with a kinked heatsink, to boot.

I'm sorry to say, but it looks like you just got a lemon... I can't agree with your rant either, as I literally just received a call from a technician to replace that kinked heatsink, after placing a call on Sunday afternoon, with emails yesterday telling me that the part was shipped. The technician agreed to come to my university, which is fairly removed from the city. That is good service, and worthy of a loud sigh of relief after my experience with a Clevo notebook.

Actually, no, I haven't repasted yet. I have torn down the notebook to inspect the insides, but I want to get that heatsink changed, even though I have good temps...

Thoroughly and wholly agree. Dell even explicitly said so in their email to me about the heatsink, which I mentioned above:

What @Mobius 1 has considered doing, is highly unethical...

 

Why don’t you run it stock and let me know how it goes?

A GMC may be 20% better than a Chevy, but that doesn’t mean it’s still a good vehicle...

I seem to be seeing a lot of people having thermal issues with this laptop all over the net.

And you can not agree with my “rant”, but it’s factual and what is currently happening in my situation, so I don’t really see it as a rant. You’re getting refurbished parts. You may be happy with that on a brand new notebook. I’m not, because I didn’t pay brand new prices for refurb parts.

 

And just a friendly reminder:
"While debating and discussion is fine, we will not tolerate rudeness, insulting posts, personal attacks or purposeless inflammatory posts. Our decision is final in these matters."

*on edit*
Also there seems to be a ton of varience in the 8750H cpus in terms of their voltages. I had a great chip in my last 9570 and the one in my current one is less than stellar (stock voltage is ~80mv higher, and it undervolts less). This can explain the difference in user experience. Sadly it's not Dell who controls the VID on the CPU, that's intel's "binning."

 

I unfortunately don't get your motorcar analogy, but my Xeon is as fast as a desktop Ryzen 7 1600X. That is plenty powerful for me.

Why would I run it stock? It's common knowledge that nearly all OEMs (including desktop motherboard vendors—and on the AMD AM4 and TR4 platforms too, not just Intel LGA 1151) specify significantly more voltage than necessary, in the interest of 'stability', at the expense of thermal headroom. A significant fraction of the members in this forum are likely to have undervolted, too.

With all due respect, you should consider doing it, too.

But let me humour you. I'm not at home right now, and I will run it stock and post my scores here once again.

 

Also, here's a Chinese review and very thorough teardown of the Dell Precision 7530. Some very interesting points, such as the separate power supply PCB.

 

Because that’s how it comes from the factory, and that’s how most of the users will use it. It’s also how Dell advertises it. It’s also because the OEM vendor, in this case Intel, has determined that at that voltage all CPUs will perform as speced, and within their errata data. Changing voltage on a CPU is a good way to introduce error. A business machine should never be overclocked or underclocked (or volted) because it’s for business. There’s no time for chasing ghosts in the machine due to these kinds of tweaks.

That’s like saying this data plan on your cell phone is unlimited.*

*As long as you don’t go over the limit.

 

My analogy was not intended as an insult, as there is plenty of data showing the lack of quality on American automobiles. My apologies that it was taken as such.

My CPU is an 8850H, but yes, your point is exactly the one I just made. This is why stating that the cooling is decent when you’re running an undervolt is not comparable at least, and misinformation at the worst - some unsuspecting person who knows little about this, or doesn’t know that someone is claiming good cooling on non-stock settings, goes and buys this laptop, then spends valuable time trying to figure out why their laptop doesn’t work as well as someone else’s. Now they engage support or return it, increasing costs for the rest of us.

Spreading that kind of misinformation is wrong, and all I’m trying to do is let those users whom this laptop is targeted, to be aware of the issues they may face running the machine stock, the way it was built and supposed to be run.

 

Exactly the same on mine

 

Users undervolt the CPU to get the best performance out of their respective machines. Optimum voltage for a particular CPU varies based on its silicon purity. A manufacturer cannot optimize voltage for every single laptop rolling off the assembly line, so they average it. Intel XTU exists with this caveat in mind.

No errors are produced by a stable undervolt: it is 'set and forget' once the initial procedure for finding a stable undervolt is followed.
