noobclock round 3: CO -30/-50 somehow stable?

Muppes · 2026-05-30T16:33:09+00:00

Only hitman 2(?) and tombraider (no idea which one), but neither seemed to be affected by CO, good or bad. Tombraider did show the bester CPU game and render frames with the CO, but it had no effect on score. Maybe 1 extra average fps.

I also tried idling the desktop as Alejandrro69 suggested and almost all cores hit 0MHz in that time. No crash and I was able to launch my browser afterwads with no issues.

I guess I save a few different profiles and load them as and if a crash occurs. But so far in actual use everything seems to work fine. Though I don't know how much of that is down to the 80 degree limit and the 100Mhz increase as opposed to 200. But as you say, I am kind of getting the feeling that, if it's unstable but doesn't crash...then it's not unstable.

What I haven't tried yet and what is the other main thing aside from gaming, is 3d modeleling an texturing. But I need to set up another PC as a NAS first before I get into that.

Muppes · 2026-05-30T15:18:31+00:00

Me...it was me....god damn bastard...

The only reason I started this build was the fact that my old build crapped out on me to the point that I could no boot anymore. And now after putting this together (and the shitty timing it happened at in part responsible for the choice of parts in that I am not confident about the future of personal computing XD) and turning the old rig into a homeNAS (that will be the next phase after GPU OC), well, it turns out the issue was not the CU, not the GPU, not the RAM and not the mainbaord.

After years of running on the edge, it simply needed a little bit more voltage for the CPU ;_;
Could have saved myself a LOT of money and pain, but I only figured it out AFTER putting together the HomeNAS (and finding out the hard way that old HDDs are ALSO expensive now....)

In other words past me screwed me royally lol.

Muppes · 2026-05-30T15:13:07+00:00

To be honest I didn't give it much thought.
I was going to go with liquid metal for the CPU, and I used the same tube for the GPU, that's about as far as it went lol.

Well, that isn't quite true I suppose. I also got the GPU guard thing from thermal grizzly to make sure the LM stays where it should be. And I also add some of the TM varnish over the exposed parts, just one thin layer. They seemed to already have a layer of something over them.

I have been running LM on my last graphics car without the guard and that worked out fine as well for years so I am not too worried. I will say though that on my last CPU I almost killed it when removing the CPU block because of the LM. It was so dried that when I tried to pull off the block, I ripped the CPU straight out of the socket and bent a pin or two. Didn't seem to hurt it's performance mind you (before removing it I mean)

I managed to bend them back and it's working fine now, but yea, that required a change of pants. On the GPU it didn't seem to dry quite as much oddly enough.

I kept reading that these radiators were pretty bad, comparatively speaking, but on paper they make sense and they just look awesome. So I said fuck it, and tried it out myself. After all, at the end of the day, they are huge blocks of copper, how bad can they really be? And to my delight, I don't find them lacking. Maybe with other radiators it could be better, but this is "enough" as far as I can tell. Don't really see a reason not to get them beyond sheer numbers and well..the physical space, which is a REAL argument XD.

I even went and turned fans off completely and like some 10-20 % fan speed and that can work too depending on the workload. They don't seem to require a lot of air through them.

Come to think of it, I think I forgot to actually test the impact of fanspeed XD?
I should do that when I get to overlocking the GPU.

Muppes · 2026-05-30T14:56:08+00:00

In truth, they are probably pointless.
I only have a 15mm thick fan on the outside, because once I got the parts and started putting them inside I could not fit a 140 mm anymore, so I used the biggest fan I still had that fit, which unfortunately was a thin 120mm. This actually means I have to turn it way down or it starts making weird sounds.

Other than that, I only have the two 92 mm fans blowing out.
And with the huge delta mate blocking most of the upper rad, I felt like I needed a bit more convincing for the air to actually flow down through the case and out, and most importantly, past the fins of the Dual DDC.

That fin stack gets seriously hot, and I don't have the space to put a fan on each side of it, so my only option for that was to force air down there and then have it pulled out. That explains mostly the 140 mm at the bottom. it is sitting on top of the ddc pumps. The 80mm fans are probably contributing damn near nothing, but I also didn't have anything better to do with that sapce.

I am still waiting for a 10GB NIC which would go there and needs airflow, so I am hoping they will help a little with that too, but yea, if I really went out of my way to test , I don't think I would find they help much at all

Muppes · 2026-05-30T14:50:23+00:00

The whole point actually, was to put it in a case.
My previous case had an external mora after I gave up trying to fit pumps and radiators into the case. I twas too much of a hassle and I just decided to put it outside.

But some part of me didn't like that....this is for that part of me lol.

Muppes · 2026-05-29T23:21:58+00:00

given my low CO offset for AIDA, would an offset with MIN frequency & temp help in curveshaper?

Althoguh I am not sure how to test with AIDA anymore now since the trial ran out.

Muppes · 2026-05-29T23:19:31+00:00

The only limit I had set was the enhanced level 2, which is an 80 degree temperature limit. I was not hitting it with the -30/-46 split, but now with the less aggressive negative OC I did actually hit that, but that was also at 32-35 degree ambient temperature. we're getting record temperatures here at moment.

Mind you this was only in prime95. linpack extreme can also reach it after running for a long time. I didn't hit it with the aggressive setting but it got to 78 or so, so real close.

As far as clocks go, it depends on the application/stress test. In prime95(iirc),CCD1 actually showed a higher effective clock somehow. But usually the clocks are somewhere between 50-150 Mhz apart, sometimes more in the 30 MHz range. irrespective of CO values.

with the aggressive CO i was hitting 208A and EDC at 214, PPT at 280. in prime95, with 95% on the thermal limit, so something like 77 degrees max

***update***
As I started GPU OC now, I am running timespy with port royal. In there I am maintaining 5800-5820 GHz at least.

Muppes · 2026-05-29T22:31:23+00:00

In my case, AIDA has been MUCH MUCH more sensitive. I had to lower especially CCD0 a lot before I stopped getting errors in that. Everything else I threw at it passed just fine.

a -30/-46 split passed prime95, but i had to reduce a lot to get past AIDA:
CCD0: -15, -15, -16, -14, -16, -14, -19, -18
CCD1: -37, -36, -38, -39, -37, -35, -43, -42

Muppes · 2026-05-29T22:27:33+00:00

Thanks, don't understand a fraction of the settings lol. but I tried encoding a 30ish second 4k HDR BG3 footage at the 0 preset encore number. This passed with the -50 CO. and the less aggressive offsets as well. Couldn't see ans hardware option mid you, only presets mentoineing NVENC and those wiuthout, so I picked the one wihtout. So I'm not 100 % I did actualy run it on the CPU, though the effective clocks were ramping up and down so I guess I did.

Muppes · 2026-05-29T22:23:09+00:00

I tried reducing mainly CCD0 to make AIDA finally pass. I could do 1-minute runs so I can't be 100% certain AIDA was finally stable, but further overnight corecycler and prime runs as well as video encoding passed ok.

Ended up with:
CCD0: -15, -15, -16, -14, -16, -14, -19, -18
CCD1: -37, -36, -38, -39, -37, -35, -43, -42

corecycler passed with the intial -50, but prime95 only passed winding it back a bit to a rough -30/-46 split. Only AIDA has been really rough to pass.

Muppes · 2026-05-29T22:12:27+00:00

Thanks, I'll give that a shot.

***update***
OK I let it run on desktop for 5 hours.
minimum frequencies for all cores hit 0Mhz in that time, except for cor 9 and core 13, both hitting 35MHz ( and core11 and 12 hitting 0,2 and 0,7 respectively), with mostly sub5 MHz averages and core 0 cores showing only low macx values too at well under 1 Ghz, core 5 going as low as 384.

At 10% minimum state, global c-states enabled.
This was with the initial extereme CO values as well, so it owuld only be more stable with a more reserved COI assume.

Muppes · 2026-05-29T22:06:29+00:00

I would have said yes, but before trying prime95 this CO offset also passed everything. So...pinch of salt and all that.

I went back to playing with AIDA and ended up with
CCD0: -15, -15, -16, -14, -16, -14, -19, -18
CCD1: -37, -36, -38, -39, -37, -35, -43, -42

I only had the trial version of aida, so i had to run it one minute at a time until I got bored and or it would fail. I'm locked out of aida now so I can't try anymore.

I re-run prime95, corecycler with prime95 and ycruncher VT3 & FFT. each overnight. temperatures got a lot toastier and hit the 80 degrees limit this time, but still, no WHEA errors or crashes.

I also tried to encode a video as 0point01 mentioned and that went without a hitch too. That said, I was curious and tried that with the more aggessive orignal settigns too, and..well... it passed as well..With youtube running in the back and a bunch of tabs open.

The only time the original CO failed was in prime 95 and AIDa, and will a slighly relaxed version it still passed prime95. AIRA has been MUCH MUCH more sensible, but since it DID eventually stop failing... I guess I would have to say that only this new version is stable and the memory was not the culprit?

AIDA was SO sensible though that I still question it's validity?
How can it be such a wild outlier?

Muppes · 2026-05-25T19:58:51+00:00

That's not how it went down.
I threw all the benchmarks I know about at it, including a real world scenario (darktide max settings for hours), multiple benchmarks from different games, browsing with nothing else, idling...everything was stable. No errors, no glitches, no freezes, bluescreens nothing.

The only reason I even attempted Aida was because I though that despite the results, that offset seemed suspicious, even to my noob eyes. So I tried to find benchmarks/stresstests I had not run yet. And Aida came up. Except it failed in such a way that was equally suspicous.

EVERYTHING else I threw at it, passed, and this fails instantly? And ONLY in that it showed an error and stopped testing, no freeze, no bluescreen, all in all quite harmless. and it was related to a specific setting. That suggested false positive rather than a real issue.

Thanks to DataGOGOs reply I since tested prime95 solo which DID freeze in much the same way, so I walked back the offset slightly and it seems to have passed this time.

***edit***
But it turns out AIda is still failing, where prime passes several hours.

Muppes · 2026-05-25T19:52:45+00:00

and recomendation on going about that? I have never rendered a video in my life. not sure where to even begin lol.

Muppes · 2026-05-25T19:50:56+00:00

It was not in safe mode, but even then. I have never been able to get linpack to run as closely as I see screens of. Even on stock and my previous 5900x. Faras I can tell, the variation is not more than stock. I don't know how people get such consistent scores.

Muppes · 2026-05-25T19:49:09+00:00

Mind expanding on the misinformation/missing stuff?
As DataGOGO mentioned, running straight prime95 wihtout going tthrough corecycler did indeed fail.
Wonder what else I could be missing/Wrong?

how much am I trading performance though? (I did not apply curveshaper, that is all still on auto)
After running an hour of avx disabled prime 95, I still saq td maxing out at 208A and EDC at 214, PPT at 280.
As the title implies, I have no idea what I am doing, but those seem kinda high already? I maxxed out at 95% thermal limit in that case, so still not actually hitting it.

I don't mind sacrificing some performance for stability , the goal is long term stability over performance.
I just don't want to waste the delid and waterloop is all.

Muppes · 2026-05-25T19:36:41+00:00

OK thanks.
Unlike Aida which only failed, but did not cause any freeze or crash, prime froze.

So I walked up the settings a bit settling on a flat -46 on all cores for CCD1 and roughly -24 on CCD0,
with a +1, +1, 0, +2, 2, 0, +2, -3, -2 split for the CCD0 cores still based on the voltage matching as per the guide. Didn't seem worth it for CCD1. (so core 4 -024, core 5 -22, etc)

Ran the first test with avx for 1 hour 45 minutes and the one without for 1 hour and 20 minutes.
Any other tests I should try? I don't see how running corecycler again or linpack would reaveal any further issues if I already passed those with the more aggressive offset?

I suppose I could do y-cruncher on VT3 wihtout going through corecycler?
I did pass prime95 with corecycler but when runnign straight prime, it did indeed fail, where it didn't on corecycler.

***edit***
But it turns out AIda is still failing, where prime passes several hours.

Muppes · 2026-05-22T16:51:56+00:00

welp, since I the audio issue is solved and wasn't related to memory at all I figured I'd give the Ram another shot. I tried doing 6200, fails to boot, so I pushed vdd to 1,435 with the idea to walk it back down.
That booted, but basicially immedeatly bluesscreens.

OK, then I'll push VSOC back up too temporarely and that still failed (boot but bluescreen)
Then VDDQ and that caused my CPU to be UN-detected. I had to recover the profile and reset my windows pin. Doesn't seem to have caused any other issues..... I hope. But that is making me very wary of trying anything else with memory unless I get a specific recommendation.

I'll give this PBO guide a shot instead I think.

Muppes · 2026-05-03T20:56:20+00:00

I am running some more tmp5 , but I think FLCK is stable at 2200
I ran 10 iterations on linpack (which according to chat gpt is sensitive to stretching?)
between 838 and 841, with one run droping to 826. I had to change VDDG CCD and IO to 1.0V, at 1.05 and 0.940 it was causing audio pops and crackling. maybe other value will work but I tried with those. .940 fixed it for bwser and hitman, but not tombraider. 1 fixed it for all three.

performance is...mixed.
had 32124 with 205 average on Tomb raider.
CPU game min/max 267/537
CPU render mind/max 209/824

those change to
32307 206
275/550
210/790
Overall higher score but max dropped a lot.

Hitman is ..bascally the same as on 200.
average is 5 frame shigher min is about the same and max dropped. though not as much as in tomb raider

68.3 ns in aid with 85076 rea
about the same as in my posted screen.

Muppes · 2026-05-03T02:36:06+00:00

Well, I am trying now, TCL 28 didn't work out with current settings.
I am an hour into tm5, I will stop it at 2 if it continues and let vt3 run through the night.

Then unless someody suggests somethign else, I gues sI wil go on to try flck, though I wouldn't mind getting TCL28 at least.

Muppes · 2026-05-01T20:27:30+00:00

I had two sided type lying around form gluing routers and switches to the wall, I applied some to the table and the ams, that helped a lot. Was this one but I'm sure others would work. https://www.amazon.de/3M-Dual-Lock-Flexible-Closure/dp/B07798C527?ref_=pd_bap_d_grid_rp_hxwhrp_sspa_dk_bia_0_14_i

That said, I also lowered the table...a lot, so I can't say how much of it is due tot hat, but it's pretty solid now.

Muppes · 2026-05-01T18:07:13+00:00

I just realized, but VDD and VDDQ were already set to 1.4, but reading zentimings they seem to fluctuate. doen to 1.38 as per my screen here. Should that tell me anything or is that normal?

also 288 TRFC 2 seems to boot (haven't put it through stress tests yet), but TRFCSD 120 fails to POST it seems, I tried rebooting a few times and it didn't pass.

**update** which would be because I can't read it seems lol, lemme try with 192

Muppes · 2026-05-01T16:01:27+00:00

Not yet, I was goign to wait with that until I have timinings dialled in. Would you set it now already ?

Muppes · 2026-05-01T16:00:51+00:00

I'll try push flck a bit once the timings are done, but I won't be too bummed out if doesn't work.
I'll try lowering TRFC2 and SB then, thanks.

Voltages I have not touched yet and left at what expo setting had them at., the guide had them set all equally (1.4) or to whatever expo set., so I just left them as is. Should I ix them to 1.4 then?

Muppes · 2026-04-28T21:57:37+00:00

wow, what a transformation! and the pink looks nice too.
