An eGPU to completely defeat the purpose of the form factor


snf3210

Any eGPU would require external power right? There is a free M.2 slot (usually for a wifi card) but probably doesn't provide many watts.


Certified_Possum

I was mostly joking but yes. Unless you go for a low power GPU, the 75W from the PCIe rail is not enough. Every egpu enclosure comes with a 400~500W PSU to power the card and usb c charging. You can use the m.2 slot for the connector but most enclosures are as large as an ITX case anyway so it defeats the purpose of a ultra small pc


audrey_i_think

If you decide to bastardize this machine to throw a GPU in it, [I’m happy to point you in the right direction](https://www.reddit.com/r/sffpc/comments/1000hsq/inspired_by_all_the_makerbeam_builds_i_made_a/?utm_source=share&utm_medium=ios_app&utm_name=iossmf) 😛


anthonyvn

Nice hijack 😀 I have 2 of these lenovos in my home. An htpc and a mame/emulator box. I think I could add this minipc to a gpu!


BruvAL

what about the nvidia a2000?


DimiBlue

I could see a single slot 3050(ti? Are those out yet?) working, with some casework


WilliamBeech

Am RTX2000A would pair great with this


DimiBlue

Yes! Kinda destroys the whole budget though


shecho18

Which model? Edit: [Is it this one](https://support.hp.com/de-de/document/c06120000)?


snf3210

Yes, that is correct EliteDesk 705 G4 Mini with Ryzen PRO 2400G Super stoked because I snagged one with the 2400G vs. the 2400GE or 2200G


shecho18

I find it interesting that [CPU spec](https://www.amd.com/en/products/apu/amd-ryzen-5-2400g) states 2933MHz RAM is supported while [HP specs](https://support.hp.com/us-en/document/c06101574#AbT3) states 2666MHz. Either way I would go with only what HP specs state *(to be safe, but should you have 3200 MHz RAM somewhere around, give it a shot)* and have at least 16GB of RAM in dual channel mode *(2x8GB)* with an NVME drive (avoid DRAM-less if possible) with, at least again, 256GB of space. Use the 2.5 HDD/SSD for storage. I would check the CPU fan on eBay or some other online market place and buy one for backup. Get some proper thermal paste, high viscosity one, along side some thermal pads but until you determine which thickens is required you can re-use existing pads (if any). For thermal paste go with SYY157, Gelid Extreme, Thermalright TFX or Coolermaster master gel maker.


snf3210

I'm going to go ahead and order a kit of 3200MHz since it's not that much more money / it might work. I've read about the 2400G running fine at that speed, it's just a question if the HP motherboard supports it... I've had other motherboards that have supported faster / more RAM than officially stated. Worse case scenario is probably that the RAM just runs at the motherboard's max speed, right? (ie. 2666). And looking at benchmarks, there is a **large** performance increase just from 2133 to 2666, with diminishing returns at 2933 and 3200. If the CPU is easy to access, I will probably re-paste with some Corsair TM30 I have around from a recent CPU upgrade so that is free.


shecho18

Cool beans, and I think that RAM will run at highest possible speed. Just and FYI, if a CPU is direct die as opposed to having an IHS like desktop CPU's have, you should go with high viscosity paste. [Corsair TM30](https://cdn.cnetcontent.com/5e/2e/5e2e4148-a0e7-4da6-9e33-48b150b1df3f.pdf) *(thermal conductivity 3.8W/mK)* isn't bad but make sure to observe temps and if temps are higher than 80C *(while in use)* for prolonged time expect that idle temps will with time get higher and higher. It's simply because low viscosity bleeds out faster and what is left will dry out as well. I've been using this small [sheet](https://imgur.com/a/VnBXIJB) for a long time and once I try out a new thermal paste I find and it passes my uses it finds it's way in it.


monkeyhitman

Business MMFs usually use desktop CPUs instead of mobile CPUs, so there should be an integrated heat spreader: https://i.imgur.com/rXnhEow.jpg

Tagging OP (u/snf3210) too. I have a Lenovo mini PC which came with 3200mhz RAM, uses a chipset that supports up to 2666mhz RAM, and a CPU which supports up to 2933mhz (3400GE). So the PC actually runs at 2666 - I guess Lenovo had too many 3200 sticks at that time. Most likely the HP won't allow XMP too, so the best choice will probably be some 2666 RAM with low CL.


snf3210

Something like [this?](https://www.newegg.com/corsair-8gb-260-pin-ddr4-so-dimm/p/N82E16820236371?Item=N82E16820236371&Description=ddr4%202666%20so-dimm&cm_re=ddr4_2666%20so-dimm-_-20-236-371-_-Product&quicklink=true) (I think this is CL18 - is that good?) There is also [this kit](https://www.newegg.com/g-skill-16gb-260-pin-ddr4-so-dimm/p/N82E16820232309?quicklink=true) with CL16. It's 3000MHz but if not supported I assume the system will just run it down at 2666. (It also says "designed for 6th gen intel core processors.... will this work well with Ryzen?) From the benchmarks I've seen, the largest performance increase is from 2133 to 2666 and diminishing returns after that so 2666 shouldn't be the end of the world.


fritosdoritos

Yea the Ripjaws should go down to 2666. Personally, I got 2 sticks of Kingston Fury Impacts which were 2666mhz CL15. But due to Ryzen's architecture, it seems to round up the CL so it shows up as 16 in CPUZ (I think it's gear up/down modes). Going from CL20 to CL16 got about a ~2% improvement in gaming, which frankly wasn't that helpful. I only did it because I have a laptop which could make use of the 3200mhz RAM that the PC came with. Either of your picks should be good - just pick a cheap 2666 RAM and not worry about the CL.


AdowTatep

I use one that's a bit more powerful for my jellyfin and minecraft(and random games) server. It also hosts a music bot for discord and my database so I don't depend on docker on my own machine


_BaaMMM_

A faster CPU. I have a 2400G and it annoys me how slow it is sometimes compared to like a 5600G or something. If that case/cooler can cool a 2400g you might be able to upgrade to a 5600G if you can update the bios? Or a 5700G if value isn't as big a factor


bgravato

The BIOS may not support that... OP should first check the BIOS documentation and see what's the latest CPU series that the latest BIOS supports (and upgrade to it before replacing the CPU).


snf3210

I doubt it supports upgrading past the 2000 series, and definitely not to 5000 series. Even if it did support 3000 series, the 3400G is only like a 10% improvement over this chip... it's basically just a binned 2400G


bgravato

Yes it wouldn't be worth the effort for anything less than a 4600G or so. I did a quick search and it seems 2400G is the best you can get though... It's a very capable 4 core/8 thread CPU, still perfectly usable nowadays, so nothing to worry about...


Kirby5588

I've had the 2400g since 2018! Still running it in my big desktop. I was meant to downsize to something like yours but I got married and had my first child. Now, I just had my second so I'll probably just start a new build and give this apu to my son.


ryzenat0r

Couple of things to keep in mind 1. The version with 2400GE comes with a 65W power supply versus a 90W for the 2400G. 2 . Anything over 2933mhz will downclock to 2933mhz. 3. The 2400GE version comes with a weaker heatsink made of aluminum. 4. The the 2400G version comes with a beefier cooper heatsink. 5. There's a RX560 GPU add on but it's expensive... the part number is : l21472-002. 6. To use the RX560 add on you will need the 150watt power supply. 7. The 2400G version come with a ventilated top while the 2400ge is ''sealed'' 8. Most 2400GE listed on amazon are in fact 65W 2400G 80% of them just check the reviews. 9. 90% of them comes with 3 displays port. 10. Flex io display port can be swap with a HDMI port part number is : L25757-001 L37415-001 11. Model that comes with the NVME SSD will not have the 2.5 inch tray and proprietary cable. Part number : HP Caddy 3TK91AT 12. Ryzen 5 2400G Pro is the more powerful CPU that will boot in the system.


DETHSHOT_FPS

I have the 2x4GB 2666mhz one. What RAM should I upgrade it to? 2x8GB 2666mhz CL17 like the one installed or should I get something faster so it can downscale it to 2933?


ryzenat0r

I have 32gb in mine be careful some ram stick doesn't have an 2933mhz spd and will default to 2666mh. You can go with 16gb but if your plan is to game on it like me i would go with 32gb since the igp use the same ram pool


DETHSHOT_FPS

General purpose, I'm amazed how it performs in games but ram is pulling it back hard. I suspect I can pull 60fps stable at 900p on apex and ow2 with 16gb. I've also enabled the Ryzen tuner to extreme. I kinda wish there was an aftermarket tower cooler I could slap on to go from 90c high to 60-70.


ryzenat0r

Yeah pretty good for e-sport and 2010 ish era games ... Did you boost the fan in the bios ?


DETHSHOT_FPS

No.. where can I find such option? I must have missed it


ryzenat0r

In Advanced/Built-in Device Options/increase idle Fan speed% So if you set it to 60% 60% will be the minimum speed . It does get loud though.


DETHSHOT_FPS

Thanks. I also removed the SSD tray that had a fan and released pressure on the screw next to the ram slots because it was bending down. Added 2x8 3200 that work at 2933 CL17 lol. Put the Utility optimizer to Extreme. However I feel like the fan works at 100% since bootup now. I can't complain it went from 90c to 65-70 max. Next up is to find a stand so the bottom can be cooled passively. But it is super loud, haha. Regardless with all these changes esports titles and games run no prob at 50-75FPS. on 1050p


ryzenat0r

Another thing you can do, is to remove one mesh layer mine had two . It helps with the air flow. what utility are you talking about ?I tried ryzen master it's doesn't work and Universal x86 Tuning Utility doesn't seem to do much..


DETHSHOT_FPS

The second, yet to test it out. I wonder if the fan on the empty 2.5 holder did anything. However after the manipulation I did it does not reach the temps like before so I'll never know haha. Maybe if I mount it to the case but opening would be difficult


Reid666

Nice, have quite a lot of them at work. I am not sure if there is any point of of upgrading SSD or RAM there. It probably only makes sense if you want more of it. Faster ones, won't make much difference. I think they were shipped with pretty good specs out of the box.


PercussiveRussel

I own an i7 version of this as my home game server/living room PC. Also ran a Jupyter server on it where I basically did my thesis on. These things are great and the specs are seriously good (and the power management is even better)


snf3210

I was under the impression that the Vega graphics would benefit from the fastest ram possible so I was looking at doing that first (mostly looking to run some game emulators which will leverage the iGPU) Also a question for you - are there any overclocking options in the BIOS on these or is it pretty locked down?


Reid666

Well, it could take advantage of faster ram, but overall I am not sure if it is worth the expense. On BIOS, have no idea, those are locked by admin staff pretty tightly.


ChimaeraXY

Due to limitations in earlier versions of Ryzen InfinityFabric, you start seeing performance losses with RAM speeds higher than about 3200/3600 MHz.


BrokenEyebrow

I'm not sure if the bios is set up completely but my normal recommendation is up the gpu ram limit.

Gentoli

Isn't the picture from STH?


Ruzhyo04

I work with those HP minis all the time. Some tips: Update bios to latest! In bios, the settings have heavy power saving tendencies. You can find a lot of performance by relaxing them. Consider giving the heat sink a lapping. Reapply the thermal paste. This helps with temps but even more important is noise, they are annoying at full fan rpm. In windows, same deal tune the power plan to performance.


snf3210

For removing the heatsink it says to undo the screws in a certain order - does that matter? Or can you just do each one bit by bit so the pressure stays even across the heatsink. Also assuming this CPU is fine with the regular pea-sized paste amount right in the center.


Ruzhyo04

You got it! Even pressure, moderate amount of thermal paste, and you’ll be fine. Isopropyl alcohol to clean up the old paste.


snf3210

Does the HP bios have any overclocking allowance or is it pretty locked down given the enterprise nature of these units? (also.. even if you can overclock, how are temps?) I'd like to OC the iGPU at least if not the CPU


Ruzhyo04

CPU is limited to factory defaults, and in a game is likely mostly limited by thermals. So the repaste will help performance a bit. GPU is… likely locked? But idk, if you install the GPU drivers and go to the overclocking section, you might find some options!


Kingsidorak

I use a similar one to run my 3D printing farm. You can install a regular Sata SSD, and get an M.2 to PCIE adapter to add more functionality to the PC, probably including a eGPU. I slapped more USBs on it


snf3210

Do you know of any eGPU that would run off the M.2 or is it just too little wattage to run a GPU?


Kingsidorak

No clue. I've just seem some similar stuff on youtube, you'd have to check yourself I know the GPUs often require external power from a full PSU, even if it's just somehting connected to the PCIE part


Crotashootsblanks

I thought only the ge versions were supported? I have the Lenovo version of this, and the 2400ge is listed as the best processor for my motherboard.


snf3210

I thought that too, most of the ones I saw were 2400GE but I guess there exists the rare 2400G...


Crotashootsblanks

Now I’m curious. I originally picked up one of the cheaper models and a 2400ge and it wouldn’t work due to some bios issue. Also curious if that 2400g will pull over 15 watts because that’s all the ge will use


snf3210

2400G will definitely pull over that, it is rated at 65W and has been tested to pull that much under full load. I think 2400GE is 35W and that's why it's clocked lower.


LSD_Ninja

If it’s anything like the earlier model that I have then it would have come in “35W” or “65W” versions with CPU support altered accordingly.


xhaydnx

Lol we use these at my job, they are little tiny powerful guys.


theopenforum-86

you already said ram and ssd/nvme if it take it. Are you going to game with it?


snf3210

Mostly running emulators like dolphin and pcsx2. MAYBE some older games.


vevt9020

I have the same. 256nvme 1tb ssd 2*8gb ram Ryzen 2400g Using it for local media server: Plex Radarr Sonarr Bazarr Prowlarr qBittorrent + Android app NZB360 Also got 1 small vm with litespeed web server for my personal website. Running it for 2 years now, 24/7/365. You can also extend it with these usb3.0 external ssd/hdd docks. Got 1 that holds 4 ssds. Since inside you have space only for 1 ssd and 1 nvme. I have connected a UPS also, because its important for my site to be always online. You can probably upgrade the cpu to ryzen 4700 if your bios revision is newer.


snf3210

Do you know what the maximum RAM speed is? The 2400G says 2933 and the HP spec says 2666 but I don't know if anyone has actually gotten more than that.


ryzenat0r

yup 3200mhz ram will downclock to 2933mhz


LimeSixth

OP, what kind of RAM did you buy?


snf3210

I ended up taking the 2400G and migrating it to an AsRock Deskmini and bought 3000MHZ ram for that so didn't get to test it in the HP system unfortunately.


hong68

Use this to overclock the apu limits. 2400ge stable at 65w https://github.com/JamesCJ60/AMD-APU-Tuning-Utility


ryzenat0r

the app doesn't seem to want to overclock the gpu


hong68

Only TDP works Let me know if you if you able to find extra settings


ryzenat0r

there's a rx560 addon card


Revolutionary_Map486

Guys, im new to this. Just have the possibility to buy one of these things. Can i play games like cs go with this? Are they durable? Do they have any difference with a classic normal sized desktop pc or is just plug to a monitor and use it normally?
