Are you using Fidelity CAS? Any other settings I should know?

I will test later and let you know

I will have a look later m8 and drop you a message thanks

Y-Cruncher users, a simple question.

I think its obvious, but i'll check anyway.

On a 7800X3d - If the stabilty test fails on ' logical core 12 ' - am i correct in assuming that is core 6 ( if 1-8 ) / core 5 ( if 0-7 ) - same core basically. Each core being 2 threaded.

Tuning Curve Optimiser, so want to double check i'm reducing the correct core.

Thx

Yup. I created a little table (logical core numbers) for CO testing to make things a bit easier.

core 0 = 0/1
core 1 = 2/3
core 2 = 4/5
core 3 = 6/7
core 4 = 8/9
core 5 = 10/11
core 6 = 12/13
core 7 = 14/15
core 8 = 16/17
core 9 = 18/19
core 10 = 20/21
core 11 = 22/23
core 12 = 24/25
core 13 = 26/27
core 14 = 28/29
core 15 = 30/31

Nice one - Thx Matt

I done the exact thing on my phone. It comes in handy.

It took me weeks to get things properly dialled in, but it’s a good feeling when you know it’s done and you no longer have to worry about any stability issues (if you did it properly). To clarify, when I say weeks, I mean curve optimiser hand tuned each core for 100% stability, whilst using as much negative offset as possible.

Hey Matt, what is your total package power at complete idle, as reported by HWinfo? I'm curious to see the difference between stock and a fully tuned 7950x3d.

Cheers

I’ll have to check and get back to you, but it varies depending on what profile I’m using. I have my tuned profile with clocked memory etc, then I have a low power profile running memory at 5200Mhz and other voltages and power limits lowered.

Cheers. I'm curious as I may make the time to do this properly, though only if it's a ~10w+ saving at idle, else I won't bother. At full gaming load, it sips power anyway. Hilarious seeing Diablo4 running at 50W for example

What's 3d like in windows 11, is it as responsive as a raptor lake system, could you tell the difference in a blind test.

I've got both rigs booting off a 1TB 990pro, can't tell a difference in windows11.

In games, also can't tell a difference (playing 4k with a 4090), if you record 1% lows they trade blows depending on the game, but 99% the same.

Biggest difference is power consumption. X3D is monstrously lower power consumption in games compared to Intel. But Intel has around 20w lower idle and in very low load applications. This is at stock for both.

36W with my overclocked profile, 6200C26 @1.59v VDD and VDDQ 1.41v.

Thanks. Will compare with mine later

 

[Dave2150]

I get 33w stock, with EXPO 6000Mhz C30, cores on stock voltage. I thought undervolting with curve optimizer would have some effect on idle package power wattage at least? Or is it only at full load that power consumption is reduced?

Sounds about right. I think with my low power profile it drops 10W or so but I'd have to check.

I think it might reduce idle power draw a little bit, but curve optimiser is reducing core voltage, not SOC/MISC voltage.

The higher idle power draw comes from the SOC/Chiplet, not the CPU cores which draw about 0.2 watt per core at idle give or a take.

Curve Optimiser @ - 31 all cores / c30 6000mt/s. Been idling/ light loads all day with no issues aswell.

Still more in the tank i think.

 

[RBImGuy]

and me just plugged it in and game.
rocks so hard btw

That’s a very good luck getting -31. My two best cores on CCD1 can’t get passed -25 but other 6 on -30.

Is it ok to go past -30? I thought -30 was max. If so I can push a bit more maybe.

Wooow I never said that I don't even know what that means hehe

Thats all i do.

 

[Gavster]

@LtMatt All ok with your suggested settings and I haven`t had to alter any voltage settings yet, can you suggest any more?
