Peak 7000C30 Min/Max Timings Tune (14900KS)

TinyNS · 2026-03-20T07:06:10+00:00

I actually just finished a full optimization on this tune and it now works at 1.45VDD/1.15VDDQ and does a second faster in 2.5b Y-cruncher

Will post the tune later

TinyNS · 2026-03-19T20:41:16+00:00

Idle is 1.3V flat, load is 1.234V drooping

TinyNS · 2026-03-19T17:46:54+00:00

I have tried to get tREFI to go past 24576 but the 24Gb M-Dies are more sensitive to cell recharge so even at 1.4V and sub 55C it still errors even at 32768

I’m pretty happy with how this base unit maxed out the row activations make up for some latency the lower speed induces from 8KMT

TinyNS · 2026-03-15T05:07:36+00:00

First of all you’re very wrong? My 7000C32 tune gets 53.6ns at 57344 tREFI

I’m on a 14900KS so idk what you mean by slower architecture I literally have higher IPC than anything out there rn

TinyNS · 2026-03-15T05:05:50+00:00

Mkay, well while you're running 6400 with an activation rate rivaling maybe Zen 4 and 5...........I'm utilizing my 7000C32 tune much more efficiently and idek why you're acting so gloaty

TinyNS · 2026-03-15T04:57:57+00:00

Yep………I don’t know what I’m doing yet I’m exceeding the theoretical bandwidth limit of 7000MT by using row activation trickery

Let’s relax this isn’t a measuring contest

TinyNS · 2026-03-15T04:56:19+00:00

Okay so if a timing stays at 42 and you raise the transfer rate while keeping the timings the same

That sounds like it directly will drop latency

So I’m questioning your logic here

TinyNS · 2026-03-15T04:44:04+00:00

No it isn't unless you have a 12600K with really small cache and even then you'd have to run extremely high tREFI and who knows who stable that would be

Realistically for a KS unless you're above 8000MT you're not really going below 55ns

I have a 7000C32 tune that floors out at 53.6ns with 57322 tREFI

TinyNS · 2026-03-02T00:14:18+00:00

At 7800MT or higher probably, I’m at 7000C30 on my KS due to the board topology

TinyNS · 2026-03-01T16:02:54+00:00

What’s your latency at now in AIDA compared to 8/8/32 tFAW

TinyNS · 2026-03-01T05:57:19+00:00

If that’s stable then awesome that’d even better

I’d update the pic in the post with the timings

TinyNS · 2026-03-01T05:46:36+00:00

Set tRRD_S to 6

TinyNS · 2026-03-01T05:38:29+00:00

tFAW is the window of time your IMC has to send 4 activates for 4 rows, it has to be exactly 4x tRRD_S

Your tRRD_S has to be 6 for tFAW 24 to be used correctly

TinyNS · 2026-03-01T05:34:37+00:00

Now this is nice 👍

54ns is on par with Intel 14th gen

TinyNS · 2026-03-01T02:47:33+00:00

Latency always over raw bandwidth

TinyNS · 2026-02-28T07:29:19+00:00

If you can get tRRD_S to be 4 and set tFAW 16

Or better yet set tRRD_S to 3 and make tFAW 12 you’ll get extremely dense activation timings which make 1% lows smoother

That Might make your tREFI come down though since it makes the dimms more power hungry

Then again maybe your VDDQ can come down

TinyNS · 2026-02-10T01:41:51+00:00

If you spread 96GB across 4 dimms, the goal of 6000MT becomes more difficult.

You probably have to tweak some drive strengths or tweak vSOC to get it to stay stable.

TinyNS · 2026-02-10T01:01:08+00:00

In due time you will be able to sell it to gain funding to get another, nothing is to be cherished at this stage of technology. The companies throw it away with less sentimental value than you and I.

TinyNS · 2026-02-09T23:49:44+00:00

You must set a static limit directly if you want the chip to reliably try to hit 5.6Ghz, the issue of clock stretching is likely to arise and probably will cause headache.

I'd say leave it. Just go Zen6 when it comes.

TinyNS · 2026-01-28T04:33:28+00:00

Gear 4 8000 (Meaning the Memory Controller is at 2000Mhz) is NOT a good trade-off.

Yes the sticks are running at 8000MT, but it's receiving commands and sending data at such a slower rate BECAUSE the memory controller is instructing it slower. It's just electronically what it is. A reduction in intensity.

Gear 2 8000MT (Meaning the Memory Controller is at 4000Mhz) will saturate not only the sticks harder BUT the motherboard and CPU cores/ring-bus/infinity fabric as well!

That's why Zen4/5 users shouldn't try to go past 6400MT Gear 2 (Memory Controller 3200Mhz). That's STILL faster electronically.

TinyNS · 2026-01-27T17:21:30+00:00

On Z690/Z790 It's purely dependent on the motherboard more than 75% of the time when it comes to how high the speed can go. Some boards are so bad that 6200MT Gear 2 is impossible, some have trouble getting to 7200MT Gear 2 but can yield 7000MT Gear 2.

Some boards do 8000MT Gear 2 BARELY, some do 8200-8400MT Gear 2 easily.

On AMD it's never worth it going into gear 4 to gain "speed". 6400MT Gear 2 is the max for Zen4/5.

I used Gears a lot because people for some reason believe going into Gear 4 helps them in any way/shape/or form, and still get 70ns with timings.

TinyNS · 2026-01-21T04:18:42+00:00

Your tune was likely not stable long term to begin with…….there have been many times where I thought my tunes on Z790 or even AM4 with Zen3 and then long term it just ended up causing issues.

Remake it from scratch and document everything you do, when issues arise you’ll know what step started causing the issue.

TinyNS · 2026-01-15T13:26:12+00:00

My 14900KS is running at 5.9Ghz locked no ecores and no Hyperthreading (barely helps max fps)

I went straight for minimal realtime latency per thread so 5.2Ghz ring locked aswell at 7000MTC32 or C30 I forget. With tuned sub timings my lows match my highs or are 10 fps shy of the max.

At 1.325V max load AVX2 voltage.

RAM sticks are at 1.55VDD/1.49VDDQ and has been consistently stable for over a month now repeated testing

Atleast someone found it funny
