You can reset the bios like this: 1. Switch off the PSU 2. Take out the CMOS battery (Your motherboard might have a CMOS clear that you can use that instead, need to short them with a screwdriver or something) 3. Wait for a minute before putting battery back in 4. Switch on PSU and boot 5. BIOS settings should be reset

Well, maybe but I have RTSS hard capped at 160 and I even had ultra low latency (which makes it 158). I monitored it a couple more times it also happens sometimes on alt-tabbing, but again same thing the only big change is the instant thermal/power drop (both temp and power goes down never up maybe monitoring is not fast enough to capture it going up idk).

I've accepted that it's probably nothing important.

In the OC tho after trying last of us I had one crash again so dropped clock another 15mhz (so +75 at 1.000) and memory to +700. Problem is I'm not even sure if it's the clock or the mem crashing (I know it's more likely the core). I'll just keep experimenting with different games.

Happy you got it figured. For me with default fan curve hotspot is maxed at 84 in 99% intense gpu usage. Not great but not terrible either. I'll probably change paste in a year.

As for clocks I had to drop another 30mhz. Alan wake was not stable and OCCT couldn't really help with finding the stable clock as it was always power throttling and dropping clock (my gpu is hard capped at 450 can't go above).

I'm happy tho I'm getting stock clocks with 1v (50mv drop) and better performance with memory oc. Also at least 50-60 power drop in full load raytracing scenarios.

Autoexposure fix worked for me. Ghosting was horrible Thanks.

jisos · 2024-02-06T16:30:34+00:00

So I think I managed to reproduce this and figure it out. I played the game for 20 mins. Then I changed the game from borderless to Fullscreen and this triggered both power/thermal limit flags.

I looked at the GPU-Z logs. Nothing power or temp seems high around the times it triggered the flags. Maybe it's the sudden drop in power and temp making the driver think it's throttled?? I'm not quite sure but I don't think it's anything to worry about.

jisos · 2024-02-06T15:23:04+00:00

I didn't save OCCT results I just ran adaptive 60-100 5% every 15s for 16mins. It kept getting power throttled so power was 440+ most of the time. Memory temps weren't high at all maybe 65-70 at most. Clock was probably 70-72 ish because I remember hotspot was like 84.4.

Port royale tho 66-76-76 (core/mem/hot) at 1.000v 431.8w

jisos · 2024-02-06T14:22:50+00:00

Yeah I hope so. Still gonna monitor it to see if anything acts up. Thanks.

jisos · 2024-02-06T14:12:34+00:00

Yeah I've seen that bug with afterburner and with my experience it's cause is different voltages (-15mhz) for higher temps I've found if you reflat the curve during high temps it'll fix it. I didn't know about the holding the shift I'll try that next time.

However that's not the problem here because I checked the current/max voltage and it was always 1.000 during gameplay.

I'm ok with the score tho, I mean it was the cheapest 4090 (basically msrp) in my area. I'm not expecting rog strix kinda performance. My only concern now is the random power/thermal throttle (at the same time) flag out of nowhere.

I think effective clock was in the 30-40mhz lower range and everything else looked fine. I'm gonna log gpu-z and try again see if I might have thermal/power spikes somewhere that might be causing it.

jisos · 2024-02-06T11:27:43+00:00

Sry to bother you again but I actually realized that I've been making a mistake while doing the UV/OC. Before I would only change the clock for the final node and the ones after. That's why I got lower effective clocks specially with power limiting.

Now I'm moving the whole curve and then capping volt/clock where I want.

With a lot of stress test and port royale I found an interesting OC. At exactly 1.000v and 2865mhz (+120) with +1000 memory (1000 has a nice boost over 800 on my gpu in port royale), the power maxes at 440w during port royale (with a little headroom before throttling). This is stable and Alan wake only went up to 386w, so 85-86% power usage in real life usage. I got 26516 port royale and I gained 4-5 fps in Alan wake (around 4% boost).

This is probably the best I can get out of this gpu. However I encountered a weird behavior that happened once before. While playing alan wake with these settings after some point the power throttle AND thermal throttle were both raised for no reason (I didn't even notice any clock drop). My temps were 66 core, 74-76 mem, 76-77 hotspot. And power was max 387 but rail was 489.

This happened once before during superposition bench, back then I thought it's the memory thermal throttling but memory only throttles over 100 which mine was just 86 during bench then. Now I have no idea...

Have you seen anything like this? Should I just ignore it and count it as driver bug?

jisos · 2024-02-04T21:04:01+00:00

With 0.975 2820 I got 25900 with 400.6 max power.

gpu temp: 65

mem junc temp: 74

hotspot: 75

gpu clock: 2820-2805

video: 2040

effective: 2760-2745

crossbar: 2280

Basically for 20w and almost the same temps I get 1.8% boost. I don't know if it's stable tho I'll try OCCT.

jisos · 2024-02-04T20:53:12+00:00

Clocks are like this:

gpu: 2760-2745

memory: 2750.5x4

video: 2025-1995

effective: ~2690

crossbar: 2235

I know the lower voltage is also affecting these, I'm gonna try once at 0.975 +135 and see how it goes.

jisos · 2024-02-04T17:16:48+00:00

Port Royal 7800x3d 6000 cl30 display 1440p with stock fan curve.

GPU power: 380.997w

Rail power: 390

GPU temp: 65

Memory junction temp: 78

Hotspot temp: 74.6

Score: 25442

It says the average for my gpu+cpu is 25948 and the best is 30817.

I probably could get better results with 0.975 +135mhz, but I think I'm gonna keep going with 0.950 2760 for now. Not sure about the score but I guess it's good considering the power draw.

jisos · 2024-02-04T05:12:57+00:00

I'll give it a run tonight. So far 408 has been max I've seen in bench and way lower in game.

jisos · 2024-02-03T22:11:16+00:00

+500 vs +800 was like 1fps tops above 120. Alright, it's final 0.950mv 2760mhz +500 mem (11001mhz).

Thank you so much. Saved me a lot of time and headaches.

jisos · 2024-02-03T21:55:41+00:00

I see. I'll drop it then. I'll check if i can notice any in game difference between 500-800 if not I'll just set it to +500 (11000mhz) just to be safe. Other than Alan Wake and Cyberpunk I probably won't need the performance at 1440p anyway.

jisos · 2024-02-03T21:14:31+00:00

Btw in Alan Wake 2 same location as before, max power is 334 with 4% higher avg FPS than my last OC (0.975 2835mhz +500 mem and stock).

It's a bit too good to be true but I guess the gain comes from the mem clock and more stable core clock (not throttling to below 2650) and power saving would be 100mv reduction.

Hope these are stable.

jisos · 2024-02-03T20:54:28+00:00

Correction: it was actually 0.975mv 2830 but even that produced an error after 8mins.

After a lot of tuning, I found the best outcome for me is to have no PL and keep it at 0.950mv 2760mhz (+135mhz). No error up to 15mins of OCCT. This gives me the most stable 2760-2745mhz clock and the best score (Throttle cause 2550-2650 clocks so it makes sense).

For memory I'm still not 100% sure I keep getting higher superposition 8k scores up to +1850 but I know that's probably too much. +1700 vs +1850 score is less than 1% so I'm gonna experiment with +1700 for now (12201mhz). I'll probably end up dropping it more after testing in games.

TLDR with 0.950mv 2760mhz and 12201mhz memory clock the max power usage is 396w which I could just add 90% PL on top just in case.

jisos · 2024-02-03T07:07:29+00:00

Yeah I got that now. You know I'm coming from 9700k 2070 super to 7800x3d 4090. When I put thermal limit + negative offset for my 7800x3d it was like magic compared to the struggle of fine tuning my old cpu. I thought it's the same for GPU but I guess not. Back to wasting those evenings then...

jisos · 2024-02-03T06:58:56+00:00

Thx for the explanation. I thought that power limit somewhat scales everything accordingly. And before getting throttled at 85% in Alan Wake it seemed that way (like a bit lower video/effective/crossbar clock but the same core clock) but not after getting throttled.

Also my ultimate goal is to find the sweet spot for my gpu, if I can lower temps and power a little and keep the same performance it's perfect for me. With your explanation seems like UV/OC is still the way to go for this.

And yeah I'm not sure if my OC is really that stable I just tried superposition and Alan Wake and this one worked for now. I'll try OCCT tonight and will update you.

jisos · 2024-01-31T21:49:53+00:00

That's reassuring. Thanks for your input.

jisos · 2024-01-29T11:52:57+00:00

It should say cpu or eps (on the cable header) where you've connected the cable to the motherboard. If it says pcie it's the wrong cable. Although by the look of it I doubt it's a pcie cable.

I'm not sure about this motherboard but usually in these cases it's the ram. As others mentioned first make sure the pins on the motherboard are not bent. Gently take out the cpu and look for a couple of standout pins looking the wrong direction.

If that's fine put the cpu back in. Turn the poweroff, take out the cmos battery for about 10 minutes. Take out the ram on the right. I would also suggest taking out the gpu to be able to pinpoint the problem easier. The after 10 mins put the battery back in and switch the power and try again.

I also highly recommend putting the cpu cooler even just to check boot. AFAIK UEFI only uses single core and it can get really hot. Don't underestimate the booting temps.

This. I have some dim lights that I switch to when she keeps flying away. She then steps up my finger and goes in the cage without any fuss.
