'Skimmed the thread.
PSU and/or PSU leads come to mind. Last time I had 'anomalous stutters' on my MI25 and 7900GRE, the 6+2pin power connectors had gotten worn and loose. Manually bending-in the contacts at the cable's plug fixed the issue.
I haven't tried it yet but I guess I'll test the PSU. Not like there's much else, right?
after reading this entire thread... only 2 things now ...
one check if it is running at pci-e x16 not 8 or 4 or 2
if thats done the next culprit could be the psu
and last is the motherboard... the thing is 6 years old... since b450 released into the market... but its unlikely in my opinion
I can confirm it's running at PCie x16. GPU-Z says so.
I'll test the PSU and pray that it's that and not the motherboard, but as I said, as far as telling signs of malfunction go, I've seen none.
a) You COULD try the 500W PSU even though it's a bit of a hassle.
Power draw when gaming would be in the neighborhood of 300W. It SHOULD be fine even with spikes. Could the current 650W be experienceing 12V droop that's causing issues with the RTX4070? Unlikely, but there's not much we can test. If it still stutters, then put back the 650W PSU.
b) MEMTEST86 - run a full pass just for peace of mind your DDR4 has no errors (put on USB stick, boot into BIOS and select it as boot device)
c) SSD - I suggest you get an SSD for Windows. Not to troubleshoot per say, but because it's a good idea. If you do that, then TEMPORARILY remove the other drives PRIOR to doing a clean install of W10 (or W11) on the new SSD. TEST for stuttering in a game that should NOT stutter. Maybe run Unigine Heaven benchmark which should run smoothly. Why remove those drives? Because hardware that's UNLIKELY to be an issue is IMPOSSIBLE to be an issue if not attached.
(I've seen weird, weird issues get resolved because a piece of unlikely hardware like a storage drive or USB device was messing things up)
Other:
"check PCIe x16"
Open NVidia Control Panel-> System Information-> BUS
(should say PCIe x16 Gen3)
*I won't be back for a while. The issue feels like it should be hardware. Odd that the RTX2060 worked. Maybe PSU, motherboard or DDR4. Baffling.
I'll do it, I'll test my old PSU to see if something changes. Nothing to lose.
Suppose I'll do this MEMTEST too.
As last resort I'll see about getting the system to the SSD.
Also, I can confirm is at x16 Gen 3. No problems there.
I don't see it mentioned, but what does various monitoring programs report during the stutters, say GPUz?
What speed is your RAM currently at?
The memory clock varies a bit, but more so on the bigger stutter than the one frame stutters.
RAM's at 3200MHz under D.O.C.P
It's obviously a graphics card issue since when swapping out the card it goes away -- so something about the 4070 doesn't play nice with the system - grab an AMD card and if that solves the problem there you go. FSR is way better than it used to be and now you have frame gen and XESS also available in many titles DLSS is not as big of a selling point as it once was.
As I said to the other guy, I'll need to either know someone who has one or enough doubloons to get one myself. I have none. The GPU + CPU already sucked the budget to themselves.
Plus I don't really want to change sides since I've bought NVIDIA specifically because of DLSS, power efficiency and the good price on the GPU.
Still worse than DLSS from 4 years ago. Unbearable in many titles. ESPECIALLY AT 1080P. And the circus method (1080p → (upscaling: DLSS Performance) 2160p → 1080p (downsampling) for example) isn't always a good idea.
If OP gets a confirmation this GPU works fine in other systems then it's bonkers to swap a GPU.
And I second the OS installation on an SSD. If it doesn't fix the original issue it'll make it much less time consuming at least.
Agreed. I'm very particular about the quality of Upscalling, and having experienced FSR, until it catches up to DLSS, it ain't it.
If everything else fails, I'll get the system on the SSD to see it anything changes.
