Dell OptiPlex 3060 - Enable NVMe Gen 3 speeds (Enable PCIe 3.0)

Enable PCIe 3.0 speeds for NVMe SSDs on Dell OptiPlex 3060

Out of the box, any M.2 NVMe SSDs connected to the Dell OptiPlex 3060 runs at PCIe Gen 2.0 speeds (Max 5 GT/s; 2 GB/s) so the speed tests look like this:

However, after this BIOS mod, the SSD can reach PCIe Gen 3.0 speeds (Max 8 GT/s; 3.9 GB/s) so the speed tests look like this:

Steps to enable PCIe 3.0

0. Disable Secure Boot in the BIOS:

   Settings → Secure Boot → Secure Boot Enable → select Disabled

1. Download the latest version of RU.EFI from http://ruexe.blogspot.com/

2. Format a USB pen drive as FAT32 using MBR partitioning

3. Copy RU.EFI to the root of the pen drive (e.g. D:\RU.EFI)

4. Reboot the OptiPlex 3060 with the pen drive plugged in and enter BIOS by pressing F2

5. Under Settings → General → Boot Sequence click on Add Boot Option

6. Under File System List select your USB pen drive. It has a name like

   PciRoot(0x0)/Pci(0x14,0x0)/USB(0x7,0x0)/HD(1.MBR,0x52DED30C)

7. Click on the 3 dots ... and select RU.EFI from the list of files

8. For Boot Option Name enter a name and click OK. This will be displayed on the boot selection screen (e.g. RU.EFI)

9. Click Apply and select Save as Custom User Settings and click OK

10. Click Exit

11. The system will now reboot. Repeatedly press F12 until you get to the boot device selection screen

12. Under UEFI BOOT: select the boot device with the name you entered in Step 8 (e.g. RU.EFI) and press Enter

13. Press Enter to dismiss the RU.EFI splash screen

14. Press Alt+= to get to the UEFI variable editor screen

15. Press the ↓ key until you get to the Setup UEFI variable and press Enter

16. Press Ctrl+PgDown keys until you see 0C40 on the left

17. Press ↓ until your cursor is at the first number in the 0C40 row

18. Press Enter and press 0 and 3 and press Enter again to update the first number in the row from 02 to 03

19. Change all 02 to 03 in line 0C40 and 0C50

20. Press Ctrl+W to write changes and press Alt+Q to exit and reboot

Test the change

Besides the obvious speed difference that can be noticed in a CrystalDiskMark benchmark, you can also check to see if the PCIe version reported in HWiNFO has changed

any idea if this works on Optiplex 5060?
i tried this, and the 0C40 and 0C50 are all 00.

I think the 50 series are already pcie 3.0 compliant

I thought so as well, but my GPU bus is 2.0 and my crystaldiskmark seems slow

I couldnt find the PCI bus speed in HWinfo except under GPU.

Any thoughts?

You need to look in the Summary screen of HWiNFO. You might have checked the 'Sensors only' option then running HWiNFO. Uncheck that and the Summary page will load.

I believe i put my summary in my last post sensors only unchecked.

here it is again for reference

Don't look the GPU PCIe version. Just check the bus part, here :

This is just the CPU and GPU spec screen. There's another window that should show the hardware summary. Look for the link speed associated with the PCI bus as shown in the screenshot at the top.

Hi,

On my Optiplex 3060 the mod works perfectly but it seems the bios edit is reset whenever there is a Windows update.

Is there anyway to prevent this? (beside never updating Windows :)

Got a 2230 SSD in the wifi slot (single lane) with an adapter on a 3060 Micro. Sequential R/W went from ~400 to ~800 megs/sec after doing this 👍
