9th gen CPU in an EliteDesk 800 G4 Mini?

People claim that you can put a 9th gen CPU into an 8th gen EliteDesk 800 G4 Mini - let's see if it works.

[@lawrenwimberly7311]

That Thermal paste ABSOLUTELY needs changed

[@adamberns]

Thanks. Good to know. I just moved up from a 600 G3 to the 800 G4.

[@etow8034]

The performance between of the i5-8500T and the i5-9500T is very minimal. Many 9th gen machines were bought with the i5-8500T to shave off a $100 off the CPU price which is a significant savings if you were buying hundreds if not thousands of these units.

[@handmedowntech]

You opened my eyes on that one. I went back and checked the G5 specs from HP and the i5-8500T 8th Gen was an official option. And it makes sense for them to offer a cheaper option.

[@etow8034]

@@handmedowntech Yeah since these were only sold to government contracts and large corporations it makes sense to buy the cheaper CPU since most of their applications is for non intensive office apps. A good thing to look for is if the warranty/service date has not expired, the service warranty for these units alone were in excess of $600usd+ and you can get parts and even in place service the next day free of charge.

[@handmedowntech]

@@etow8034 one of my G4s still has the extended warranty with a year to go. Crazy.

[@etow8034]

@@handmedowntech Great, just phone them and get a new fan and PSU before it expires, these are the items that usually go bad on the fourth year.

[@suprerxero]

Both are same silicon but one is clocked tiny tiny bit higher so performance is nearly identical, its called refresh or rebrand.

[@handmedowntech]

Surprising they even call the 9500 a new generation

[@suprerxero]

@@handmedowntech 13th gen and 14th gen same thing, only that 14th gen is new so prices are higher than 13 gen.

[@user-cg5xv4zz2b]

I went to HP site for this PC - there is no 9th gen cpu's there. so this is interesting that bios can identify it. that means that there is code there for that cpu. Maybe bios sharing between mulitple computers.

[@handmedowntech]

I was surprised too. I believe it's the Q370 chip set. It supports 8th and 9th Gen. Q370 is what the G5 has too

[@user-cg5xv4zz2b]

@@handmedowntech I am not a cpu genious and know more about the old AMD than Intel. but from my experiences with AMD, the computer starts in a 'generic cpu' more - where it can run simple code. remember the code in the bios has to run to set things up - that included id of chip and then setup of its particular. If cpu was not identified - stop. I had a cpu that failed to work ( even though right AMD socket ). Had to downgrade to another cpu to get it to work. so for AMD - socket type was not the all deciding factor - the mother board had to support the CPU ( even if socket was correct ). and also, on the AMD motherboards - if you bought the wrong cpu, you have to put a downgraded cpu in - flash to newer bios - and then magically the cpu that failed now works. so Bios code ( for AMD ) must supporrt the cpu. and the second example was ryzen motherboards. I have seen chats on the subject and even saw notes on vendor's web site that as to what cpu requires what bios level. I cannot talk about Intel - it is not my specialty

[@handmedowntech]

Sounds pretty close to the Intel thing too. It was interesting that some K processors work in the G4 but others dont

[@walterlegere1403]

If you're going to swap chips around why not upgrade it to the Core i7-9700t to get the extra cores? Not sure if it would be worth the cost though.

[@handmedowntech]

I'm not sure the G4 will support that 8 core CPU

[@exploringgodscountry]

super helpful! What happens if you need a bigger power supply? Do you know how to upgrade the power supply? Would be cool to throw a 9th Gen i9 in there.

[@handmedowntech]

You can simply get a higher wattage power supply. I believe the 150w is the highest used on the units - mostly for the G4 with an added CPU and for cases where a "K" type CPU is used

[@exploringgodscountry]

@@handmedowntech ended up buying one of the G4 computers. They are awesome. I cannot get it to boot from an m.2 drive though. Fiddled with it for a few days then gave up. You figure that out?

[@handmedowntech]

So is this an m.2 that you did a fresh is install of windows on? Or was this a drive with an existing windows?

[@exploringgodscountry]

@@handmedowntech I ghosted the SSD to an M.2. Thing is though the boot manager won't show the m.2 drive even if I pull the SSD out. It's really weird.

[@handmedowntech]

Have your tried both m.2 slots?

[@antoine0569]

Good video Are the cpu special to HP cpu or just generic and do you need to use a 9 th gen t processor oh and also do an bios update on the g4 mini and try a 10 gen cpu

[@antoine0569]

I have a elite desk 800 G4 mini 65W with a i5 8500 and I would like to upgrade to a 8 the gen full (means not a t processor) i7 and with your video I wonder if a full i7 9 th gen and if a 10 the gen full works I use it for VM a lot so I need a lot of CPU power

[@handmedowntech]

Nothing special on the CPU, not specific to HP. G4 can take 8th and 9th Gen. 10th Gen may be pushing it but maybe others have tried and will comment.

[@antoine0569]

Ok thanks

[@TheKing-uk3pu]

What can be installed on it of the highest grade of resin?

[@handmedowntech]

I'm assuming you're talking about CPU? If you have a 120w power supply you can install a i7 8700k processor. Now we know it will take a 9th Gen processor but I'm not sure if it would allow for a i7 9700k

[@vicolin6126]

Interesting. I tried this about a year ago, but with 65W 800 G4 mini (with perforated cover). Tried to upgrade from a i5 8500t to a i7 9700 but the computer would not boot. It beeped and the power button lit up red. If i remember correctly the error code meant that the cpu was not recognized. Fully updated BIOS (at the time) and used a 230W power supply for good measure, but did not work. If anyone did the same upgrade and it worked, let me know :)

[@handmedowntech]

I know it won't take a i7-9700k. Tried that in one of my other videos. I was using a 150w psu

[@TheKing-uk3pu]

Is it possible to install an Intel Core 5 processor? Generation 9 Replace Ryzen 5 2400 G

[@handmedowntech]

Is that the 120U processor? Based on the Intel site it looks like that is a different type or size of socket.

[@ernestgalvan9037]

It is NOT possible to swap Intel and AMD. TOTALLY different architectures (sockets, chips, etc)

[@downundergarage6968]

The only diff between the 8th and 9th are few 100 Mhz of clock speed.. no other difference at low to mid range. At high end they have added extra threads to combat AMD but you will not use these in the G3/G4.

[@handmedowntech]

Do you mean G4/G5? Didn't think those would work in a G3

[@johnc4929]

Do you know if 65W cpu will work on 35W mini? I have 800 G3 mini 65W and my friend has the 35W without cpu and he wanted to see if the motherboard is still good. He wanted to make sure before buying the 35W CPU. I couldn’t seem to find any videos of yours testing 65w on 35w machine. Thanks!

[@handmedowntech]

For a quick test you will need a 90w power supply. You can put in the 65w CPU without or without the heatsink and see if it boots to the BIOS. The system info will tell you the CPU installed.

[@johnc4929]

Thanks! We plan on doing this in a couple of weeks. I think if we can get into the bios that should be good enough to prove the mb is good, let alone if it boots and starts the OS. We will also use my nvme and 8gb memory from my 65W to see if it boots. And yes, I will use my 90 psu. You don’t happen to have the video on YT do you?

[@handmedowntech]

@@johnc4929 maybe watch the one I have on the G2 65w. In it you see what happens when the PSU is only 65w. You can also see in the 9th Gen video how I test with going into the bios by holding down the escape key

[@johnc4929]

Thanks again! Will look into those videos! 👍

[@mokhesengramaisa8202]

so that means it will work on HP elite desk g3 800 ( g9 processer)

[@handmedowntech]

That I haven't tried. I would be quite surprised if it did.

[@etow8034]

Normally downgrading an older CPU to a newer machine is doable, but upgrading a newer CPU to an older machine is a hit and miss as it is not officially supported.

[@mokhesengramaisa8202]

okay

[@dfbess]

thermal paste is your cpu's best friend..

[@bitheroes68]

I mean while everything is open it might have been a good time to clean it off and apply a fresh spread of it...

[@handmedowntech]

That and a friendly heatsink and fan 😀

[@TheKing-uk3pu]

Can I communicate with you privately?

[@handmedowntech]

I would prefer to keep all comments in the public space so that others can benefit from our discussions.

[@jjb7920]

It would be interesting to know if the i9 9900t will also work in the G4. In this video, you're going from a 6c12t cpu to a 8c8t cpu. I wouldn't expect much of a performance boost. The 9900t would give you 8c16t with a max turbo boost to 4.4 Ghz.

[@handmedowntech]

There may be a viewer out there who has tried this.

[@robindelaguila9202]

Except he didn't go from a 6c12t cpu to a 8c8t cpu, but from a 6c6t to another 6c6t, which is based on the same architecture but with a very slight frequency tweek. Having the same performance is really to be expected.

[@handmedowntech]

Very good point. I was wondering why it was so easy to put in the 9th Gen. I'll have to school myself on the nuances of CPU stuff like 6c12t.

[@jjb7920]

@@robindelaguila9202You're right. I mixed up my research with this videos info. I have the 8700t, and was looking at replacing it with 9900t.

[@robindelaguila9202]

@@jjb7920 if you want a short answer, you will not gain anything when it comes to GPU since both 8700t and 9900t use the same iGPU. On the flip side, you might see a mild increase in CPU performance. Though since it's in a small form factor device, I'm really not sure you'd get THAT much more performance. The 8700T is probably kneecapped already.

[@TheKing-uk3pu]

The offer is all the same and no different

[@handmedowntech]

Not sure what you're referring to. Search eBay or Amazon for 2230
