Precision 7530 & Precision 7730 owner's thread

But besides turbo, normal clocks and thus sustained continuous speeds are different? And the 8700 is available in notebooks as far as I can tell. 8700k and 8086k being faster still... hmm

 

Hello,

Welcome everyone 2 days ago i bought brand new 7730.
Max I7 Quadro 4200, IGZO display, 8GB ram for upgrade

Everything seems to be nice but i found out some quality issues.

1. Fingerprint sensor works veery bad. I could not log in via this sensor to windows. (I read this is normal for 7730 that sensor is low quality) After few times of pointing it i realised it is not rigidly placed anymore. I took a picture and it is easy to see that it is not parallely mounted to the housing. I think some glue went off. What a shame dell
2. I noticed some screen bleeding in corners i attached it on pictures. Should it be touted?
3. Fan is sometimes strangely starting to medium revs and after that it turns off. like 2 or 3 times. After that it turns off permanently. It occurs without no load. Did someone have this issue.

What do You think, should i send this 7730 for warranty concerning those issues?

You can swap out the RAM yourself. For warranty purposes, you are still covered if you install aftermarket hardware, but Dell has the option to request that you restore the system to its original hardware state before performing service (if the tech thinks that the RAM may be causing the issue). In practice, I've never seen them actually make this request.

8700 is a desktop CPU. If it is available in notebooks then the notebook maker is installing a desktop CPU (this happens sometimes) and it is important to be aware of this when making comparisons — no one claims that "similarly named" desktop and mobile CPUs have the same clock speed. Dell only uses mobile CPUs in their laptops. There is a decent selection between the 8750H, 8850H, and 8950HK which pushes up against the highest clock speed offered in a desktop CPU (on the turbo side). In practice, the CPUs will operate for an extended period of time well above the listed base clock but below the maximum turbo clock unless you take steps to reduce the heat output (undervolting, better thermal paste application, etc.). I have the 8850H and without modifications it bounces between 3.7 and 3.9 GHz under an extended CPU load.

The Wikipedia page has a list of all of the CPUs with their classifications and clock speeds.

Sigh.... unfortunately even with mDP attached to the external monitor instead of TB3 the PCH is always in the mid 80s deg C. Only when using laptop display does the PCH temp go down to 30s.

Does anyone else see in HWiNFO that your PCH temp is 80+ deg C all the time when running an external monitor through TB3 or mDP?

I really wonder if having the PCH at such a high temp for long periods of time if that could do some kind of damage.

 

Anyone had any issues with their Dell machine after the October windows 10 update? I'm getting "Internal Power Failure" after putting the computer to sleep or hibernate. Dell may need to update some drivers....

 

I updated and then right click open the context menu, and put cursor on top of new, the UI freeze, explorer.exe crashes. also the Intel graphic card icon in the context menu is gone too. also premier color stop working

 

The 8700 was designed and intended for desktop use, but indeed there are a few brands offering laptops with a socket that use those desktop parts. That said, they still face the same challenges as other laptops.

The 8700 performance you refer to was most likely in it's intended use case; a desktop with a sufficient power supply and proper heatsink. In any laptop that you'd be able to carry, you'll have to make compromises.The 8700 has a much higher power consumption: If you want to get desktop performance in your laptop, that means a big, heavy heatsink, resulting in an overall extremely large laptop.That higher power consumption also means less battery life for a given capacity.

If that's a trade-off you're willing to make, then you'll get the most out of one of those models. But a desktop with the equivalent parts would be cheaper and more powerful. Most people who buy a laptop do so because they actually want the mobility benefits.

 

Same for me. Just installed new Intel GPU driver and see if that changed anything

 

Thanks for clarifying the desktop/mobile CPU issue. I wasn't aware that one could actually use them in a notebook.

 

It's also prudent to note that notebook CPUs and desktop CPUs very in their factory-set TDPs by a factor of 2—for example, the i7-8750H has a TDP of 45 W, while the i7-8700K as a TDP of 95 W. They typically run at about 25% higher than that, too; my Xeon, for example, typically runs at ~ 60W under load, and I'd expect an 8700K to run at ~120 W, too.
