RM 850x not enough for 3090?

GM7
 Share

Hi, So I had a thread before but it's quite old so I created a new one. So To quickly sum up: 

I have INNO3D GEFORCE RTX 3090 ICHILL X4 with RM 850x power supply my monitors were turning off and pc would black screen crash. And I ended up sending my graphics card back to the store for them to repair it. And I waited 4 months and they said they fixed something with temps but I didn't notice any difference I think they basically sent me the same card back. But I did the testing again and now with 5 fans in the case and an open side panel and room temp of 20°C, I monitored my temps and the highest was VRAM 90 and the max for the card itself was 70 and it still crashed (monitors turn off and but you can still hear the audio for some time). As I understood the limit is 110 before some artifacts happen. But for what I tested when I turned power saving mode on pc It didn't crash since, so I'm wondering if it could be some power spikes or something.
 

My PC specs:
CPU: AMD Ryzen 9 5950X 16-Core Processor, 3401 Mhz, 16 Core(s), 32 Logical Processor(s)
GPU: INNO3D GEFORCE RTX 3090 ICHILL X4
Power supply: Corsair RM 850x
Motherboard: ROG STRIX X570-E GAMING
RAM: 24GB 3000MHz
Main Monitor: 1920 x 1080 x 240 hertz
2nd Monitor: 1920 x 1080 x 60 hertz
CPU Cooling: Corsair Hydro Series H115i Extreme Performance Liquid

what configuration is this ram because 24 gb is probably going to be a bunch of sticks and not just a few.

 

also yeah you'll probably want 1000w or more for a 3090 as the power spikes can crash a system pretty easy

it shouldnt have taken 4 months.... I think they were straight up just playing with your  GPU then returned it after. That seems WAY to extreme. 

 

Ive had to fix a fair bit of computers with the RM 850 PSU with 3080ti, 3090 and 3090ti. It seems some of the PSU's really dont like the high GPU load, and can cause crashing. Although this one looks like it is artifacts and it looks like memory artifacts.

 

One of two things you can try, Underclock the memory a little bit and see it it changes, undervolt a little and see if it helps, or change the PSU to a 1000W one.

8GB one is G.SKILL 8 GB DDR4, 2133 MHz F4-2133C15S-8GNT
16GB I am not sure  I can't find the original document, but I think it's corsair 3100 Mhz I think.

I know this is bad im planning to chage them soon. I did mem test on both and they passed.

Yeah I didn't really think of that I believed them because they said they are going to send gpu outside the country since they are not "repairing them here" but as I see it I basically got the same GPU back. But they temporary gave me 3060 until this one got back since it was taking soo long.

mem test doesn't do a whole lot. It only lets you know the memory is currently working , it doesn't let you know when it randomly stops working. Basically a "we couldn't reproduce the error" brush off.

that being said that 3090 probably just want a bit more juice and your unit doesn;t seem to want to supply it.

I'm worried this was the case, They said a new card would be arriving if the issue weren't fixed. But I think I will just return this one and upgrade to 3090 ti and if the issue still occurs I will buy a new PSU.

Its plenty. My tiny little SF750 handles my 3090 just fine at 400W. The PSU would be shutting down the system if you reached a limit with it.

5800x/3090

You were already told issue wasn't the PSU when you had issues in February, and the issue still isn't PSU related. Why do you still keep insisting that it's PSU related?

That BSOD code is a graphics problem. Try running DDU on your system and then a fresh install of your video drivers. Looking over this and the older thread, I see artifacts which indicates faulty VRAM on the graphics card.
