HP 705 G3 MT CPU Upgrade to Ryzen

[GSzabados]

Hello,

I have a HP 705 G3 MT originally shipped with a AMD A10-9700. I tried to upgrade the CPU to a Ryzen 7 Pro 1700X, what was one of the official purchase options from HP.

The computer has been updated to BIOS version 2.37 without any issue, but the computer doesn't boot with the Ryzen processor.

Actually, it powers on by itself when the power cable is plugged in, the fans starts spinning, the HDD powers on, etc, like it boots, but actually it doesn't. No output to the screen, it has a dedicated GPU. No POST error message, and I cannot power down the computer with the power button. 

So, is there anything else, what has to be set to use the Ryzen CPU, or the CPU is just not supported, maybe it is DOA. (But the no POST, and automatic power on is really odd.) The computer has POST beeps and LED when started without CPU, or without CPU power.

Any advice would be appreciated! 

Best Regards,

Gábor

this computer model has NEVER supported the ryzen series of cpu's

i believe you are confusing the  system's APU Ax-xxxx series cpu with embeded Radeon R7 graphics with ryzen 7 cpu's

see the link below for supported APU series processors

Hello,

Thanks for the reply.

This document states differently:

https://www8.hp.com/h20195/v2/getpdf.aspx/4AA6-6314ENUC.pdf

As well just a random search on Google with the phrase, HP 705 G3 Microtower Ryzen.

https://www.insight.com/en_US/shop/product/1MM33UT%23ABA/HP%20INC/1MM33UT%23ABA/HP-EliteDesk-705-G3-...

I have found a document before which states that some configs had even a bigger PSU as well for the dedicated GPU.

So, does it support Ryzen processors or not?

Best Regards,

Gábor

This is another config but the SFF with Ryzen 7 Pro 1700x.

again,..............you are confusing the APU's onboard ryzen graphics core with a discrete ryzen 7 CPU which is a completely different thing

the link you provided ( https://www8.hp.com/h20195/v2/getpdf.aspx/4AA6-6314ENUC.pdf )

on the first sentence the header clearly states  (Pure performance and enhanced visual experience) 

then states Enjoy the powerful performance of the latest 65W AMD Ryzen™ 3 PRO 

if you google this you will see it's specs do not match the ryzen 7 cpu's

the hp quicklink i sent you also clearly states what this model uses for a CPU

https://support.hp.com/us-en/document/c05265587#AbT1

you have also physically tried a ryzen cpu in place of the systems APU based processor and found that it does not work

the last link you sent:

https://business.currys.co.uk/catalogue/computing/desktops/windows-desktops/hp-elitedesk-705-g3-sff-...

CLEARLY STATES IN THE DESCRIPTION IT USES THE APU SERIES PROCESSOR

[GSzabados]

Please excuse me, I am not confused by the Radeon R7 and the Ryzen 7.

The document what I posted before clearly states that these computers were sold with Ryzen processors (CPU) and not only with the AMD A-Series processors  (APU).

But here is another one:

http://www8.hp.com/h20195/v2/GetPDF.aspx/c05238044.pdf

Page 8 lists the Ryzen processors, and later on the 7th and 6th Generation APUs.

At the end of the document there is a change log as well, where it mentions the the Ryzen 7 PRO 1700X has been corrected, because the X was missing.

One of my favourite is the 400W PSU for dedicated AMD RX 460 and 480 video cards. What hasn't got any other mention anywhere else.

And probably this user was mistaken as well, because couldn't identify correctly the A-Series APU.

C'mon, if the B350 chipset doesn't support the Ryzen 7 PRO 1700X, then what mainboard supports it from the HP 705 G3 line? I cannot find any reference at all that this line had a different mainboard, but if they do, what is the SKU or Product number of those?

and yet again the pdf you link to states the processors are the "APU" line

https://www8.hp.com/h20195/v2/GetPDF.aspx/c05238044.pdf

from the linked PDF:

Choice of form factors: Desktop Mini, Small Form Factor and Microtower

Latest 7th generation of AMD Pro A-Series APU4  <------NOTE CPU IS FROM THE "APU" Series
• 6th generation of AMD Pro A-Series APU4   <------AND AGAIN NOTE CPU IS FROM THE "APU" Series (MT/SFF)

and the pdf clearly states which cpu line fits which model as each uses a different motherboard/cpu line

SFF/MT (ryzen cpu)

Desktop "DT"  APU series cpu

your original post states: I have a HP 705 G3 MT originally shipped with a AMD A10-9700. 

THIS MEANS YOU HAVE A "DESKTOP SERIES"  not a SFF or Microtower

[GSzabados]

 HP 705 G3 MT

MT == Micro Tower

And all of these are desktops, none of them are server line, or laptop!

[GSzabados]

The Desktop Mini has never received Ryzen CPU for this line.

But I am NOT talking about a Mini!!! I am talking about a Micro Tower (MT).

Where are the spare parts list which support then the Ryzen processors? Where are the product number for the mainboard?

[GSzabados]

I have a feeling that you must have some sort of dyslexia and cannot make a difference between

DM = Desktop Mini

SFF = Small Form Factor

MT = Micro Tower

I am talking all the way about a Micro Tower model, MT. But you are insisting on a DM.
