Boot loop/ Startup issues after 2080Ti upgrade

[Dr Tyrone]

Hi,

  Hoping someone here could be of some help in regards to some issues I had immediately following a GPU upgrade from an MSI 1660Ti to an EVGA 2080Ti XC Ultra.

I believe this could be something simple I'm missing but I can't figure anything out.

Specs:

MOBO: MSI B450 Tomahawk

CPU: Ryzen 5 2600

GPU: EVGA RTX 2080Ti XC Ultra

PSU: Corsair RM850X (850W)

RAM: Corsair Vengeance 16gb x2

SSD: Samsung 970 evo plus M.2 500GB

HDD: WD 1TB 7200RPM

CPU Cooler: Hyper 212 evo

OS: Windows 10 Pro 64bit

 

MSI MOBO BIOS Version: 1.30 - 11/8/2018

 

Let me start out saying, I didn't know I had to run 2 seperate cables for the PCIe port on the GPU. Once I did that, there was a noticeable difference but issues kept up and still nothing's been fixed.

 

PC works fine in regards to opening, closing and using programs but does not perform well.

 

When issues started, I pressed the power button on my PC, everything would light up, fans spin, but after a few seconds of no image displayed it would shut off, wait a few seconds and turn back on, few more seconds turned off, then back on. If i was lucky it would only do this twice. 

 

Symptoms:

-Low FPS 110FPS CoD MW 1080p(I Had 130-140 on my 1660Ti)

-Unstable FPS (hitting 280-300FPS on other games then dropping to 120FPS within 5-7 seconds)

- If i boot up without going into BIOS 8 times out of 10 it'll boot fine, if i go into bios, even if I don't change anything, once I exit it will shut down after a few seconds and restart by itself a few seconds afterwards and loop this maybe 3-4 times.

- AMD Ryzen Master says my EDC is at 119% and TDC at 80-90%, reset CMOS, it'll go to 99%. I'll put power settings on balanced and it'll fix itself and drop my cores to 3.2ghz. This never happened before.

 

What I've tried:

- Reset CMOS 3 times

- Disabling Precision boost OD in BIOS 

- Changing to Windows Balanced and AMD balanced power settings, lowering minimum idle state (I don't remember exact name) for CPU to 5%.

Image on Reddit shows results after all that.

- Disconnected everything from PSU except for CPU and MOBO and it booted fine so I assume the startup issue and everything else is GPU related.

- I overclocked the GPU and it ran fine up until now so I returned it to default settings and still nothing.

- Drivers are definitely up to date, I could delete old and install new but I read if you go NVIDIA to NVIDIA GPU, deleting old isn't necessary.

 

I believe a fresh Windows install may fix it or a BIOS update but wanted to see what I can do before that.

 

Thank you everyone

Bump...

 

Haven't received any solid info other than, the R5 2600 has EDC locked from someone on reddit. Hasn't happened to me before and I think I'd notice a red / yellow EDC TDC number. Gonna update BIOS on my next free day and likely do a fresh Windows install.
