3070Ti OC, Ryzen 9 3900x, 3 storage devices. Is an 850w PSU enough?

[TTG24]

Hello there.

 

Some may know of my journey of a post I made about my stuttering issues I had for many months and recently gave up on. However, my issues have been getting worse, or at least got worse.

 

Doing some investigation with the new GPU I got, it seems I might be hitting a limit... perhaps?

 

Within the title, is it okay to have those kinds of specs with an 850w PSU? I feel I could be not getting enough power.

 

EDIT: If some are curious to know what "journey" I speak of, clicking me will tell you about it.

I have a Corsair RM850x running a 5900X, RTX3060ti OC, 32GB RAM, M.2, 6TB HDD, Blu-Ray drive and six RGB fans. Most load I've seen with twenty cars chasing me in BeamNG was around 450W, have only added the Blu-Ray drive and swapped a couple fans since then, so maybe another 10W load now? I may be adding another 8TB HDD, so at most I think I'll be drawing around 500W.

 

You don't mention your specs or what your new GPU is. 3070-3090 should be fine with an 850W, but transient surge loads can cause problems. However, I don't think your PSU is to blame for the stuttering. Usually a PSU issue means total shutdown and hard starts / restarts.

 

As to the stuttering, I would start checking your motherboard's QVL list for your RAM's specific SKU / part #. Reason being, I've had some strange issues on a recent new build that appears to have been, at least in part, due to RAM that was not on the board's QVL list for my processor series. This may not have been a thing before, but it certainly seems to be becoming a thing.

 

Unfortunately the only RAM I had to swap for troubleshooting was an older purchase of the same RAM. Which made it seem like it was the motherboard, requiring total disassembly for RMA. Naturally, service "couldn't duplicate the issue", so it was returned.

 

Meanwhile those DIMMs caused issues in another machine, and now both seem to have failed. The original build and temporary test bench now appear to be running great with RAM that was on the boards' respective QVL. So I would start by looking at that.

If you're only pulling 450W, then case closed for this oddity.

 

I've done the QVL over 10+ times. Money wasted you could say.

 

I do appreciate the suggestion and response though.

I think that depends. Through partially disassembling a new rig and reseating RAM / GPU, checking connections TWELVE TIMES IN FOUR MONTHS, it never occurred to me the RAM could be the problem. Maybe for some processors, it's not a big deal, but I assure you, it certainly made a difference on both a 5900X on an Asus Tuf B550-PLUS board and a 3600X on an ASRock B450M-HDV.

 

Both support DDR4-3200, but they didn't like the Ballistix BL16G32C16U4B.16FE x2 I had. The ASRock now wears Ballistix CL16 BL2K16G36C16U4B (BL16G36C16U4B.M16FE1 x2) and the Asus now wears Patriot PVB432G320C6K, neither have any issues with stuttering or crashing. Now, as it happens, the BL16G32C16U4B.16FE that was in these machines has apparently failed -- neither DIMM will POST, so at the very least, you may have faulty RAM, QVL or not.

as mentioned, psu dont cause stutters, it'll just shut down or something

i suggest you look elsewhere to solve your stuttering issues

yes

i ran a 3900x (undervolted) and a 3080ti (undervolted) on a 550W psu, i doubt 850W isnt gonna be enough for a 3070ti even on full stock load

[191x7]

The 850W is more than enough. I'm running a 5900X paired with a 5700XT on a 550W PSU and it's not even peaking.

 

Let's check on the stuttering issue...

1. Latest BIOS?

2. Latest Chipset drivers directly from AMD?

3. All drivers updated (ioBit Driver booster)?

4. Tried XMP on and off?

5. 3Dmark Firestrike and Timespy scores close to the numbers they should get?

Depends on the brand and model of the PSU. There are enough junky 850w PSUs I wouldn't use with these specs.

Again, I do appreciate the suggestion of RAM. However, like I mentioned, I have tried 10+ different kinds of RAM kits. It would be improbable for it to be the RAM.

I have a 1300W coming tomorrow. I do have HX850 Plat Corsair, but it was bought refurbished.

1. Yes

2. Yes

3. Yes

4. Yes

5. Close enough.

 

I noticed when turning off "FULL" speed for my AIO in BIOS, things seemed to have loaded better. When it was on, and changes saved, getting into BIOS was not possible for some reason.

PSU can cause intermittence as stated from Corsair themselves when contacted, though I will standby and say it isn't that severe. AMD as well.

Thanks for the response.

sure, but i've tripped my RM850x's OCP/OPP way too many times to confirm that it doesnt cause stutter, it just shuts down my entire system

 

what i suggest you try instead is switching from pcie 4.0 to 3.0 and see if it helps, as i've seen quite a few cases of odd performance being solved this way

Has been done. Improved performance like you have said, but did not solve the stuttering issue.

Trust me, a lot has been done to fix the stuttering.

This post here while although long has everything you can find of being suggested and tried.

i skimmed through the thread, the stutters are detectable by rivatuner (or whatever you use to display frametime graph), so it's not a display issue (i've had a 240hz display that caused stutters because the display driver inside the monitor wasnt up to snuff, causing framedrops)

however, im a bit surprised because i dont think i've seen anyone suggested you use a spare drive, install a clean copy of windows on it, and just run games on it with minimal things installed, see if the issue occurs, this usually allows you to tell if it's hardware (or bios setting) or software issue

Cannot remember if I have stated this suggestion or if you missed it when skimming, but I have done this already.
Fresh install and many bought drives later, still same issue. Someone had suggested doing Ubuntu. Happens worse on there.

i see, then it's most probably a hardware/bios issue

have you tried setting bios back to stock? including running your ram at JEDEC speed (non XMP/DOCP, 2133MHz)

by fresh install, did you use a windows installer USB stick?

BIOS definitely isn't the issue, I can positively say. Hardware is questionable.

Everything has been at stock/defaults since mid July.

 

Yes.

 

What seems to have fixed my problem, however, was refresh rate. For some odd reason going above 120Hz on my ASUS TUF Gaming VG279QM I got last year destroys everything. Yes, I have used a new cable and different GPU. Very disappointing.

Other things I did was get a 1300W PSU and go back to Windows 11. Before installing the OS, I made everything at stock except A-XMP. I have 3200 instead of 3600 since on the 3900x specifications it states 3200. I'm leaving the GPU do its' own thing and PBO off.

 

If anyone has a recommendation for a new monitor, do let me know.

1080p, 240-360Hz, smallest in" preferred, G-SYNC (not "compatible"), eye care.
