Upgrading HP EliteDesk 800 G3 SFF

[NOT_Merlin]

Hello,

This is quite an awesome thread that you started here. I have the same machine as you and I wanted to upgrade it and I got stuck with the small PSU issue.

I think an i5-8500 can work on this motherboard and it's supported for WIN11. I am trying to get a spare one and upgrade my pc.

I will try to provide you with an update if I get the cpu and make the upgrade.

@NOT_Merlin,

Thank you for your kind words -much appreciated!

Yes, this thread contains all the information you would ever need to smoothly ADD a secondary PSU in order to power your (external) GPU. One observation: I had purchased a powered PCIe X16 to PCIe X16 3.0 (Male to Female) ADT-link riser extension ribbon cable at extra expense, but that additional power feature is not needed. 

As a matter of fact, if the ADT link is powered by the secondary PSU, it will not allow the ATX 24-Pin to SATA power converter to completely power down your secondary PSU + PC when you try to power down (shutdown) your PC.

Anyway, I am very interested indeed to hear if the i5-8500 would work on an HP EliteDesk 800 G3 SFF -you would be the first one to show that, because so far only 6th and 7th generation Intel processors have been known to be compatible with its motherboard's Intel Q270 chipset.

Good luck!

Kind Regards,

Dear Forum,

Found a good deal on eBay on Samsung M378A1K43CB2-CRC 4 x 8GB PC4-19200 (DDR4 2400 MHz) RAM sticks.

Even though my current fancy gaming G.Skill Ripjaws V Series 4 x 8GB PC4-19200 (DDR4 2400 MHz) RAM sticks work fine and certainly look cool, they do not run at 2400 MHz but at 2133 MHz, even though the internal G.SKILL RAM 2400 MHz XMP profile is enabled.

And the reason why it is stuck at 2133 MHz? -Long story short: HP excluded XMP/DOCP settings from its BIOS. Other performance enhancing software programs, including Intel's XTU, are similarly disabled to adjust RAM and processor speeds.

Merde! -as the French would say.

However, research suggested that some RAM (including the aforementioned Samsung) memory does run at 2400 MHz, which is the maximum RAM speed possible on an HP EliteDesk 800 G3 SFF.

Since my goal was to Upgrade this legacy HP desktop to its absolute maximum, this purchase is probably my last performance enhancing acquisition for this desktop.

Dear Form,

And what do you know: the Samsung 4 x 8GB DDR4 (PC4-19200) 2400 MHz M378A1K43CB2-CRC RAM I purchased and just installed (thank you, eBay Seller, for the fast processing & shipping!) runs at the max speed allowed by HP EliteDesk 800 G3 SFF's motherboard: 2400 MHz!

What fancy "gaming" RAM couldn't do in an admittedly restrictive HP hard/software electronic vault, was effortlessly achieved by this Samsung RAM -this RAM brand shown through brightly, and not for the first time either, I should mention:

@NOT_Merlin,

Any news yet pertaining getting the i5-8500 to work?

Dear Forum,

Upgraded this Intel i7-7700K powered HP EliteDesk 800 G3 SFF Gaming Rig to Windows 11 Pro, using the link suggested by @Paul_Tikkanen: Windows 11 Upgrade Hack on Any Hardware | Dong Knows Tech.

Working great!  Encountered zero system crashes or other system (in-)stability issues that would substantiate Microsoft's claim that (most) 7th Gen Intel processors are not meeting their, quote: "principles about security and reliability".

The Intel i7-7700K processor, for all intents and purposes, meets all the functional and security requirements (TCE, TPM 2.0, secure boot) Microsoft claims are prerequisites for W11.

When you compare 7th Gen and 8th Gen Intel processors, there are basically no fundamental differences between them except increased core/thread numbers, bigger L3 cache, higher boot clock, higher RAM speed support and CNVi (Wi-Fi/Bluetooth) support that is basically completely irrelevant for a (gaming) desktop PC.

And here you go, Microsoft:

Dear Forum,

@Paul_Tikkanen, seriously: this Upgraded desktop has never run as well as it does now since installing W11!  Check out my latest UserBenchMark results here: https://www.userbenchmark.com/UserRun/52135692!  -Almost got "UFO" status for "Desktop" performance too!

I agree with you.

One of the advertised benefits of W11 was that it was supposed to 'run faster' than W10 and it has not disappointed in that area as far as I am concerned.

I have updated my stable of Dell and HP desktop and notebook PC's and every one of them run better on W11 than they did on W10.  No crashes, no problems.  Worked fine with Windows 7 drivers I had to install on some of them.

This includes models as old as dc7800 CMT with an E8300 processor to a Dell Optiplex 7050 MT with an i7-7700 processor.

Notebooks as old as a HP Elitebook 6930p with a P8700 processor to a HP Stream Pro G4 with an Intel Celeron 3450 processor.

I have a HP Envy x360 with a Ryzen 5-4500U processor that is fully W11 capable, and I use that PC to cross reference the updates Microsoft is releasing to make sure all of my other PC's are getting the same ones.

So far, they have received the same updates the Envy x360 is getting.

I wrote to one forum member my opinion is that Microsoft made a big mistake opening the flood gates to any PC running W7 to be able to get the free upgrade to W10.

No doubt they were swamped with support requests from folks out there who couldn't get their W7 PCs to work right on W10.

I'm thinking part of the reason for the strict hardware requirements was not to repeat the same mistake twice and be flooded all over again with support tickets.

By levying the strict hardware requirements for W11, this greatly reduces the population of PC's that would potentially need W11 operating system support.

Dear Forum,

Continue to succeed in finetuning and improving my HP EliteDesk 800 G3 SFF's performance:

[EDIT:] For comparison's sake, my HP EliteDesk 800 G3 SFF performs as well as the much newer HP OMEN 25L Desktop GT12-0xxx, with an HP 873C motherboard, AMD Ryzen 7 3700X processor and an RTX 3080 graphics card, see this example: HP OMEN 25L Desktop GT12-0xxx Performance Results - UserBenchmark.
