Why Does My HP PC TP01-3003w (318K3AA) Seem to Get PCIe 4.0 Speed on NVMe SSD?

Hello,

I've got over 40 years PC experience and am usually the person giving technical answers instead of asking them.  I'm having a problem because my HP is TOO GOOD! 🙂

I own a TP01-3003w PC (318K3AA) with 12th Generation Core i5 and love it.  I thought this PC has a PCIe 3.0 bus speed limitation.  After upgrading to a Samsung 990 Pro 2TB NVMe drive I seem to be getting FASTER PCIe 4.0 speeds around 6,900 MBs according to Samsung Magician!  While the drive operates AMAZINGLY, Magician can't report my actual bus speed details due to a software "conflict" with the Intel VMD storage driver configuration which is forced in the BIOS/UEFI.

Also, I get similar high performance USB speeds around 900 MBs on the USB 3.x ports with a Samsung T7 drive rated for 1,000 MBs.  Other newer economy PC models don't come close on the NVMe or USB.  How in the world am I getting this blazing fast speed on this motherboard?

There must be a REAL reason for it.

Thanks!

Hi:

Below is the link to the parts list for your notebook's product number:

HP PartSurfer

It comes with a HP 'Reno' motherboard.

Below is the link to the Reno motherboard specs:

HP Desktop PCs - Motherboard Specifications, Reno | HP® Support

The motherboard has an Intel H670 chipset.

According to the Intel chipset specs the PCIe version is 4.0, which is why the Gen 4.0 SSD is running near its rated speed.

@Racing96mustang,

The HP Pavilion TP01-3003w was an upgrade project of mine, and I can confirm firsthand that this system absolutely rocks: Solved: Upgrading an HP Pavilion TP01-3003W (318K3AA) - HP Support Community - 9254350.
