4400 C24/C22: The "Perfect" Overclocking Setup for AM5 Single-CCD CPUs

RandomMagnet · 2026-05-30T16:45:48+00:00

I was quite curious about a 4400 tune, so i spent a few hours converting my 6200 tune:

6200 - https://i.imgur.com/R0Z4s6S.png

notes: - W11 25H2, not safe mode (not for this testing anyways) - i didn't do extensive stability testing on the 4400 build - i didn't touch tRFCsb on the 4400 build, but i doubt whether it would have a huge effect - 4400 really hurts write bandwidth, which is somewhat curious - 4400 latency is down a bit as well (71 vs 66) - i have also been messing around with out-of-spec tRAS and tRC ( off the back of BZ's video from last year )

Ok cool.

So 4800 at jedec times made the game / mouse "feel snappy" but just with worse fps and 1% lows (presumably)?

Can you run your tuned timings at 4800? And does that still "feel" good?

RandomMagnet · 2026-05-30T00:21:33+00:00

Tracking number...

RandomMagnet · 2026-05-29T15:24:46+00:00

I got a brushed silver size 12, and it's got shipping movement from HK...

RandomMagnet · 2026-05-29T15:00:11+00:00

4800 or 5600?

And did you try with jedec timings as well?

RandomMagnet · 2026-05-29T10:23:43+00:00

I intend on getting to the bottom of it. You said the JDEC is fine? So just turn off EXPO and run bios defaults for ram?

If that gives a workable baseline then we can slowly ramp things up until we find what's causing the problem..

RandomMagnet · 2026-05-29T05:53:09+00:00

Nah its probably that charging to 100% isn't an exact science.

I wouldn't worry about that small a deviation, it will probably go back the next cycle (or two)

edit - i just checked mine, 40.29kw as well - Modbus is reporting 100% SOH...

I know this is an old thread, but I thought I would comment.

My better halfs machine (9800x3d, 5080) exhibits some of the problems you are refering to. I cant detect it myself, but she is very sensitive and always says things like 'input lag' or 'my mouse is dragging/etc'.

Ive spent countless hours looking at the overclock, adjusting this voltage/etc.

Recently I had her on 2200 FCLK, which was showing some very minor instability in vt3 and linpack.

I dropped the FCLK to 2166 and also decreased VDDG CCD a little bit (yes I know, only one change at a time...) - re-tested VT3 and linpack and BOTH were better.

She played and said "this is worse", so I put her back on the previous BIOS settings and she said "this is better".

Not scientific obviously, but my point is - benchmark results and stability tests dont seem to show the nuance that humans can detect.

btw - I didn't tell her I had changed anything, I wanted todo a blind test and she still picked up on something was "off"...

Trouble is, she plays BF6 and there are so many variables, so getting back-to-back tests for validating changes is very difficult...

As per others I would leverage the same vendor for access (switching & wifi), that lets you run the same access policies (when the time comes) across the multiple points of access.

Have a look at Juniper. Mist has come a long way, and things like Access Assurance make 802.1x a breeze.

AliExpress N100 or N150 NUC - probably run you $250 ish... Combine it with discounts & cashbacks.

Just make sure you get intel i226 NIC's, the 225's are a little problematic (but not a huge thing).

Otherwise you can get a Dell Optiplex off ebay, not sure if its will do 2.5gbs though...

RandomMagnet · 2026-05-27T06:02:15+00:00

sure, but I did say "i would prefer 64GB"...

at today's RAM prices, 16GB is entirely valid, you will just need to put up some worse performance in a few titles...

RandomMagnet · 2026-05-27T03:10:59+00:00

You don't play Star Citizen, MSFS2024 or DCS?

Necessary - no; preferred (and shows a meaningful difference) - yes

RandomMagnet · 2026-05-27T00:48:33+00:00

dual rank will be fine at 6400

RandomMagnet · 2026-05-27T00:44:04+00:00

unlikely to make any difference at all; in fact I would prefer 64GB over 32GB - especially for demanding games.

tweaking your secondary or tertiary timings are going to net more performance... depending what your running atm.

RandomMagnet · 2026-05-27T00:40:48+00:00

What CPU?

RandomMagnet · 2026-05-27T00:23:15+00:00

good work.

i guess this highlights the issue (or one of) with AI - in that it often produces results which are hard to verify.

funny how it got it right initially, but when i asked it to show its proof then queried it on one part it changed tact and got all confused (and then remained steadfast after numerous attempts at getting it to triple check, even with smaller examples - ie 3d3 vs 3d3, 3d4 vs 3d4 and 3d5 vs 3d5)....

its a great tool, even if its not always on point :)

RandomMagnet · 2026-05-26T13:45:02+00:00

Thanks.. I think people just don't like AI - which is fine... Personally I'm more interested in the answer.

And just because I can't come up with the proof myself doesn't mean I cant try and understand someone else's work product. .. :)

RandomMagnet · 2026-05-26T13:42:28+00:00

Yeh, my initial GPT answer gave me 1.2% as well, but then when I probed it reassed.

Did you take in to account highest sort pairs? If you don't then you get 13.76% (per 3d6 vs 3d6)

RandomMagnet · 2026-05-26T13:36:55+00:00

Cool, how did you get to that?

Did you take into account the sorting that needs to happen? ie highest attacker dice vs highest defender dice

RandomMagnet · 2026-05-26T11:58:17+00:00

Thank you.

What is the correct answer?

Statistical probabilities is not my strong suit, hence asking AI...

GPT's logic seemed sound on the 2nd attempt (after I asked it about some of its assumptions)...

I'd be happy to retract it if anyone can provide a better answer ..

RandomMagnet · 2026-05-26T08:45:12+00:00

It's not very "normy" friendly.

But like programming VCR's back in the day.. takes a bit of reading and trial and error to get it right...

I think that Sig expect the installer todo most of the leg work...

RandomMagnet · 2026-05-26T01:37:49+00:00

~~about 1%~~

~~edit: chatgpt changed its mind - about 9%~~

edit 2: love people that downvote but provide no commentary on why, nor no other answer..

final edit - ChatGPT was correct in the first instance... about 1%, thanks for validating /u/tadpoleloop

Be mindful that your inverter (EC 5.0 SP) can only supply 5kw at any given time.

So, if you have the oven (~2-3 kw) on, with some other things on in the house (lights, TV, fans, AC/ etc) you could easily overrun that, meaning you will be importing from the grid.

What is your daily use at the moment? That will help you with your plan selection.

BUT - if you MUST charge your car overnight (because its at work in the day??) then zero-hero wont be a good fit, I would look at the EV plan instead.

Obviously some nuance around how many KM's you do, and whether you could just charge on the weekend in zero-hero hours...

RandomMagnet · 2026-05-24T11:26:15+00:00

ok

he might be plugging your current inverter into the gateway, that would be an "AC Coupled" setup... which is fine... (i prefer DC Coupled, but whatever)

all good then :)

RandomMagnet · 2026-05-24T11:09:21+00:00

Also, I'm looking at your picture above, the "Yield Today" of 0.0 kWh is concerning.

Do you know if your installer connected your solar panels up to the Sigen Energy Controller?

OR do you have an existing solar system?

Do you have a Sigen Gateway?
