I need to upgrade my MOBO for my New HD

[rgh43-]

My PC is just out of warranty  in Oct with HP. This issue has been going on since i bought this PC.  What I'm trying to find out from HP is what MB I should install to get the speed up.  They can’t answer your question, can’t seem to transfer you to anyone that can.  You are transferred to someone who is supposed to help you with your question and they end up telling you they will give you to someone else but you will have to pay $15 and do so without any guarantee that they will be able to answer the question or help you at all. Really, $15 to answer a question?  I bought this HP at Costco, an HP690-0067c that has a Mother Board that in my opinion is old outdated and not fit for the current types of Hardware on the market. As I have found out you can’t upgrade or really do much in the future with this PC, you will need to buy a new one.  Had I any idea of this and all the shortcomings of this PC I would not have wasted my money.  It will not support a Samsung 970 EVO NVMe Series 500GB M.2 PCI-Express 3.0 x 4 Solid State Drive (V-NAND) to its fullest extent. It will only support it to PCLe Gen. 2 X 4 when the Samsung HD is capable of 3.0 X 4. This is ½ the speed either write or read that the HD is capable of.  I want to or tried to find out from HP Support which of their MB’s will support my Samsung fully but none of the people can even tell me that.  My MB has a M2 plug in it for the new drive but doesn’t help when the MB will not support it. 

I have spent a great deal of time on the phone with support for NADA.  What I need and cant seem to get from HP is what MB can I replace the existing one with to achieve the correct speed from my Samsung 970 EVO NVMe Series 500GB M.2 PCI-Express 3.0 x 4 Solid State Drive (V-NAND) to work up to the speeds it is capable of, currently I get Write or Read speeds just over 1600.  According to Samsung I’m getting half of what I should get.  Other forum help answers I get tell me I should be over 3000+.

Greetings,

Welcome back to the forum.

I am not a HP employee.

HP 690 series PCs use a proprietary: chassis, motherboard, and power supply.

The chassis and MB do not conform to standard uATX specifications. The power supply does not use a standard 24 pin MB connector.

You will have to buy or build a new PC if you are not satisfied with this PC.
