Precision 7530 & Precision 7730 owner's thread

Well the adventure begins. Received my 7730,UHD, i7-8850H, 16GB, P3200, 256GB M2. Never used Win10 some experience with Win7, mostly linux. I have a new 970 Pro I would like to install linux on (not installed in 7730 yet). When I turn off raid in the BIOS and select AHCI I can't boot into win10. I get a nice blue screen that says Your PC ran into a problem and needs to restart. Well restart for you. If I turn RAID back on in BIOS boots to Win10 OK.

I need to enable AHCI so I can install 970 Pro.

In BIOS Restore setting presents three options, BIOS defaults Factory Setting and Custom. What is the difference between default and factory.

Thanks for your help

 

Covered in detail earlier in the thread. Short version is...
Set Win10 to boot into safe mode
Boot - but enter BIOS before Win10 starts - change to ACHI
Boot again, let Win10 load in safe mode and it sets up drivers for ACHI automatically.

 

SK Hynix 16 GB 72b-SO-DIMM 1333MHz (DDR4-2666 / PC4-21300)
Model #: HMA82GS7CJR8N-VK

 

Unfortunately, this "224TT" datasheet (link has changed, now it's this: https://comparison.dellproductbrochure.com/it/product/59) it's wrong (or at least is outdated and not updated by dell).

I've contacted pretty much every italian online store who sell this preassembled unit and everyone agreed about P2000 rather P3200 inside 224TT model.

One even told me that a client purchased that unit thinking to get P3200 but then discovered the presence of P2000.

Only one told me that only first units on the market had P3200 (he remembers to have sold few ones with P3200) but then dell somehow changed specs.

So now every 224TT on sale has P2000, that's for sure (unless there are some very rare unsold units with P3200 as warehouse fund still around if what i was told by that reseller is true).

The only chance to get P3200 is going for "XXN03"
(https://comparison.dellproductbrochure.com/it/product/60)

But it's a 17,3" notebook. (few mistakes i think even on this as i don't see any "WLED Touch" display available on dell online store for 7730 as every FHD panel is labeled as "UltraSharp IPS non touch with 72% color gamut" so any chance to get a poor quality 45% color gamut panel like on 7530 should be 0%; also battery is not 240Wh, maybe they misundestood with psu wattage that it's 240W).

The cpu is i7-8850H.
Now according to several sources this cpu, despite missing the "k" at the end, it's partially overclockable (up to +400 mhz).

I've searched through this topic and found out some users with this same cpu:

Could you please tell me if you're really able to overclock i7-8850H on your 7530/7730 ?

"XXN03" has 16 GB ram (2x8). If stock ram is installed under the keyboard, i would like to expand it with this crucial ram: "CT2K8G4SFS8266" (dell stock ram is generally cl19)

About "CT2K8G4SFS8266" i've found this bad experience though:
(http://forum.notebookreview.com/thr...n-5520-7520-7720.800132/page-72#post-10808796)

His 7520 failed to POST (everything worked again after he removed them).

In this other message:
http://forum.notebookreview.com/thr...n-5520-7520-7720.800132/page-73#post-10808992

he told that dell support recommended him "8GB - 1Rx8 DDR4 SODIMM 2666MHz, Dell Part # A9206671" (but i don't understand why as the user already wanted to buy a 2x8 configuration so "16GB - 2Rx8 DDR4 SODIMM 2666MHz" would have been the better choice...)

Then he reported that even so called "dell official ram" were incompatible with 7520, so only going with same exact ram modeompatil already installed (in his case Kingston XF875V / Dell part Nr F875V) would have worked out.)

Do you think that newer precision model like 7530 (or 7730 should i choose to buy XXN03) still 'suffer' this incompatibility ?

Last question: stock 512GB SSDs are self-encrypted ?

I mean, in case of any kind of hardware problem, if i take the SSD out of the notebook and put it in a nmve-usb adapter so i can temporarily use it as an external ssd connected to another computer, will i be able to access files and folders on it ?

Or being self-encrypted, i will see NO files and folders ?

Hope you guys can help me !

 

The CPU will dynamically throttle up to the maximum turbo speed (4.3 GHz for a single-threaded load, a little lower for multi-threaded). Are you looking to overclock beyond the maximum turbo speed? This system doesn't really have to thermals to handle that. As is you will hit thermal throttling under a sustained load unless you undervolt the CPU. Anyway, I haven't tried to overclock it but normally the Precision BIOS is locked so you can't overclock even if your CPU supports it.

We have three 7530's upgraded with Kingston memory and that is working fine. I chose CL19 to match the Dell modules that came in the system. Note, the modules that came in the system were not Kingston, they were Hyundai, and the two different types are working fine together.

Some of the drives support the "self-encrypting" feature but it will not be enabled unless you go out of your way to turn it on.

 

Thanks Sorry I was a impatient, your instructions helped

 

So you're basically saying that editable power limits are way more important than unlock multiplier for an "overclockable" cpu in order to overclock it ?

For instance: 8950hk has unlock multiplier by default because intel designed this cpu this way, right ? If we set (pure hypothesis) 5 ghz as 1 core turbo boost limit, even if ac adapter is capable to feed the cpu and also we have the thermal headroom to reach and sustain that frequency, the REAL frequency will only be determined by bios-locked pl1 and pl2 values ?

My target was trying to bring 8850h to i7-8700 performance level.
As i mentioned, i've seen that 8850h can be overclocked up to +400mhz more than stock turbo values.
I7-8850H has 4.3 GHz as 1 core turbo boost limit and 4.0 Ghz for all 6 cores.
By adding +300 Mhz (if temps allow it) 8850H can match i7-8700 desktop cpu stock turbo limits on 1 core (4.6 GHz) and all 6 cores (4.3 Ghz).

And of course i will surely undervolt 8850H.

In this post:
http://forum.notebookreview.com/thr...0-owners-thread.820539/page-140#post-10819920

with undervolt at -145 mV, he gets a stable 4.6 GHz on single core, while multicore gives 4.2 GHz and then throttles down to 4 GHz, but stays there (i9 on 7530 not repasted).

So in my case i would get a 8850H on a 7730 (so bigger and maybe better cooling ?), so if undervolt is stable getting 4.5-4-6 on single core is a nice extra if possible.

So could you please check on your 7530 unit if you can overclock 8850H ?
Also if you use hwinfo, at cpu info section what you see at cpu power limit ? Is it reported [Unlocked] ? Could you also share a screenshot of it ?

 

I have not tried overclocking, it is of low interest

I see that you have 7730 with 8850h+p3200 (same specs i'm looking for).

If you use hwinfo, could you please share a screenshot like this ?
https://www.oldergeeks.com/downloads/gallery/HWiNFO64_main_2.png

I want to see whether [Unlocked] is being reported or not at "CPU Power Limit 1 (long duration)" and at
"CPU Power Limit 2 (short duration)"

About overclock, i just wanted to know if xtu or throttlestop allow you to edit turbo values. Would be great if you can tell me this.

By the way, on idle is your 7730 completely silent or fans suddendly "wake up" and after a bit "go to sleep" ?

Hope you can help !

 

At idle it is silent, my main interest is getting archlinux installed, maybe someone else can help you with HWinfo, throttlestop
