HP EliteBook 8470p + GTX 970 - problem(?)

Hi,

I have eGPU set with HP EliteBook 8470p, graphics card GIGABYTE GTX 970 OC Mini, EXP GDC Beast v8.4d and PSU Corsair CX500.

Earlier I used GTX 1050 Ti, but I got error 43 on newest driver and I changed this on older, but better GTX 970.

But, after change graphic and set configuration, I have problem, because my graphic with load 60-70% TDP (max to 75% TDP) in benchmark, my PSU make strange noise inside and it could after 5 minutes turn off.

For test, I could with other PSU - CHIEFTEC 550W, problem is too and I know, that PSU is efficient.

For 2nd test I borrowed PC from friend, I install my PSU Corsair and GTX 970, everything ok, no noise, TDP level on 90-100% in benchmark.

I wasn't testing another GTX 970, because I don't have a chance.

I thought about change on GTX 960 4GB.

In my head, I don't have any logical idea, maybe someone have?

Same problem with Elitebook 8570p with an gtx 1060 oc and same config, atx vs550 with exp gdc 8.4.

My elitebook don't have igpu, the dgpu (amd) drive the internal lcd.

just 120fps on cs:go in high ( not ultra ).

 

Ps: Gtx 1050 ti can work i think, but with older driver, all new driver make this error.

 

 

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

CX500 PSU is a good quality, and high AMP rated PSU. I would not expect a GTX970 to load it and have it switch off as a load protection measure unless it's a faulty unit. Your successful test with the Chieftec PSU suggesting the CX500 is indeed likely faulty. Hope I'm reading your testing correctly.

On eGPU, Corsair and CHIEFTEC have a problem, but in Desktop PC everything is ok, so PSUs are 100% good. My GTX 970 in PC don't have problem too, only on eGPU.

Check your PSUs rail configuration (12V1/12V2) and which rails are being used by the eGPU adapter wiring. With some eGPU adapters like the PE4L 2.1b, attaching to the PSU molex connectors would see it draw only a single rail from the PSU. A desktop system can use the CPU, molex, PCIe and 20/24 pin connector, drawing power from all PSU rails.

I connect eGPU set to my CHIEFTEC 550W with 12V1/12V2 rails (V1 rails for 8-pin PEG and V2 for 4-Pin CPU to adapter) and nothing - the same problem.

Earlier, I tried connect my eGPU by HDMI to TV SAMSUNG 50" and everything ok, I ran benchmark, loading and... 1-2 seconds benchmarking, PSU turn off.

Some power supplies have stability problems if there isn't a load on the 5V rail. That would explain why your supply works in a PC but not with the eGPU.

 

You can try putting a dummy load on the 5V rail. A 10W resistor in the 10-20 Ohm range should work.

I tried connect some hard disc to SATA and fans to MOLEX, but problem is still.

I made mix - I connected my Corsair 500W to Desktop PC (ATX 24-pin and CPU 4-pin) and PCI-E 8-pin to my GTX 970. Next, I connected my second PSU CHIEFTEC 550W to eGPU adapter (ATX 20-pin and CPU 4-pin to 8-pin cable adapter). I ran benchmark, and no noise, TDP on level up to 90-95%.

My PSU shouldn't have problem with use same 12V rail, because I saw test on eGPU with Lenovo Y580, EXP GDC Beast v8, MSI GTX 970 Gaming and Corsair CX500 - . I have the same cables connection.

I can make test with another GTX 970, I bought MSI GTX 970 Gaming and probably it will arrive in Tuesday and I will make test.

Hi, I'm back, I have MSI GTX 970 GAMING 4G now, but... main problem still too 😀

But, this strange sound from PSU and.. EXP GDC Adapter or graphics card.

I read in Web, that adapter can have a security before high rail load on example PE4H adapter.

And I have a question... what is different between PCI-E power from PSU and PCI-E power from 6-pin output in adapter?

GTX970 coil whine is a know issue. Here's a video showing what is sounds like so can confirm this is what you are hearing:
