kateri mini PC?

Ajej. Sedaj pa res ne vem več, kaj je z vidika čim bolj neslišnega delovanja bolj pametno.
Pred časom sem Beelink vračal ter bil potem zadovoljen z NUCOM.
Predvidevam, da ASUS na NUCU ni spreminjal sistem hlajenja in je z vidika glasnosti enak.

Tega sem vzel. Cakam na dostavo. S popustom pride 289€, dodati pa moras svoj ram in disk. 32GB in 1TB bi moralo biti vecinoma dovolj.

Advantages:
- It's silence
- It's performance
- It's expandability (64GB, std. NVMe SSD)
- It's Network (2.5GBit)
- It's silence
- It's silence (I really like it. ;-) )

Poleg tega očitno tisti ventilator ni dovolj. UM773 ohišje je iz dveh prekatov. V enem je CPU/GPU s svojim ventilatorjem, v drugem pa RAM in SSD brez aktivnega hlajenja. Pod obremenitvami se posledično zadeva sesuva kar dosti uporabnikom.

Obstaja seznam tweakov, ki ga koristijo tisti z UM serijo in težavami. Priporočam branje celotnega prispevka pred nakupom. Med drugim:

"It has come to light that the UM773 memory configuration is flawed, regardless of whether the memory is factory-installed or user-installed. The RAM configuration defaults to 4800Mhz, but it does not read the memory's on-DIMM data on the correct voltage/timings. This results in all RAM, irrespective of the set speed (which can be overclocked), being set to an arbitrary timing value. As a consequence, voltage, extended timings, and configurations are not used by the Mini PC, which can lead to overheating and instability.

All RAM has JEDEC tables for the stock 4800 Mhz speed for DDR5, and some RAM has XMP tables for overclocking to the manufacturer's specifications. However, none of these are referenced or can be set within the BIOS. Although the timings are stable, they are heating up many chips to unexpected levels, especially considering that there is no airflow in that compartment. Additionally, this creates a hazard of not providing the chips with proper power or over-provisioning power, as all RAM sticks have varying requirements due to their configurations."

*Many users are reporting a simple ram swap away from the stock Kingston Value RAM as a fix for many random crashes and freezes. This is likely due to the aftermarket RAM having better tolerances for the arbitrary timings in the BIOS.

Glede težav s povezljivostjo, o katerih sem bral naokoli, pa je verjeten razlog tole:

UM773 Noted Issues (unresolved):

It has been observed that using multiple USB ports simultaneously or through a hub (consisting of one standard 500ma device and 2-4 ~150ma adapters) on UM773 can cause an overload of power draw. This overload can lead to the m.2 and USB controllers for the wifi/BT chip becoming unresponsive or unrecognizable. Ideally, each USB port should be capable of handling 500 ma of power, and the USB 4 port is advertised as being able to handle 3 Amps. However, if there are less than 1.2 amps of draw via a hub for either USB C port or when all the USB ports on the rear are used by low-power adapters, it can cause power issues and turn off wifi/BT features. To avoid this issue, it is recommended to use a powered hub.

So pa baje hlajenje izboljšali pri UM790 Pro..

To je ta, o katerem sem govoril:


Ni ravno najelegantnejši, ampak baje solidno deluje, vsaj kolikor berem mnenja na Amazonu.

Ampak 620€ je malo kruta cena.
Jaz sem odstel manj kot polovico tega zneska za 5800h 16/512gb.
Sicer je slabsi ampak imam raje 330€ v zepu:)

Verjetno velja zgolj do polnoci..
Oglasevan kot tihi mini pc za 289€ + postnina, z ryznom 6600h, rdna2, 16gb ddr5, 512gb ssd:

@ZveeZ, je bil včeraj večji popust s kuponom? Sprašujem, ker gledam danes in še vedno se lahko aktivira kupon za 60 EUR popusta, ampak je cena s tem že 339 EUR (+ poštnina 12,94 €). Ali pa je tisto bila cena z italijanskim DDV-jem?

Vceraj je bila cena 289€ brez kuponov.
Sem ga kar narocil.

Sedaj imam tega odvec:
https://www.amazon.it/gp/aw/d/B0D8HV5RMK

Vceraj sem ga stestiral in je bil ventilator noro glasen do instalacije driverjev. Sem pa nasel v biosu nastavitve za ventilator in se ga ta konkretno utisat.
Ce bi ga kdo rabil, ga prodam za 300€ (kupil za 290) vkljucno s postnino.
Ce ne, ga vrnem amazonu.

Aja, pa win sem namestil iz nule in ga kasneje resetiral, tako da je sedaj gor nedotaknjen win z driverji.

So imeli kar lepe popuste za te midrange mini pcje:)

Nkeaj v tem stilu:

Piše, da naj bi imel UM790 Pro izboljšano hlajenje

Cold wave 2.0: UM790 Pro uses an innovative liquid metal cooling system and offers an active storage and SSD cooler (quiet fan + large heat sink). Cold Wave 2.0 is a cooling solution with good performance and low noise. This allows the UM790 Pro to fully exploit the performance of CPU, memory and SSD. The metal housing further improves heat dissipation.

A je kdo zasledil kakšen test ter dejansko razliko v glasnosti?

A si že dobil ter testiral to zadevo?
Kako je z glasnostjo?

Dobil danes. Vendar je DOA. PSU dela, masina mrk :(

Ne razumem kratic :(

DOA - dead on arrival
PSU - power supply unit

tudi temu zmanjka na koncu rama , tele arhitekture se bodo precej spremenile tokom prihodnjih let.
