What are you cooling this with?

 

[StAndrew]

The PC is just a rendering machine with an old Corsair H115i 280mm AIO with 2 NF-A14 and 2 NF-A12x25.
If the CPU is delided with a custom loop the frequency under heavy load can go higher.

Hmm... would recommend investing in a custom loop. I'm not saying you're wrong here but I'm not convinced you've tested this long enough to make any definitive conclusion. At least I'm not ready to risk my $600 investment

I also think something is buggered with your volt tuning. I used this Guide and tuned my LLC ( AC_LL & DC_LL) and VF curve in accordance and my my volts are at 1.5 but my R23 watts are 290W, occasionally peaks to 300W. I'm rock steady form 6.2 light load to 5.7 heavy load. IIRC, settings were 60, 60, 60, 60, 59, 58, 58, 57 but I would generally get a 200Mhz boost at light and medium load even though TVB was disabled. Custom loop with direct die block.

But I'm now just running stock with LLC curve optimized IAW the above guide, Asus MCE disabled and with a 100W and 10*C drop, I'm still boosting very close to the same clocks as the OC with R23 only dropping 1k points.

With this voltage you cannot run 6Ghz all-core in games. You got 5.7GHz all-core with undervolted voltage instead.

I couldn't. Maybe adjusting the LLC tune but it failed at 6.0 all core R23 (posted though). However, I agree, I have a lot more headroom in the CPU and cooler. Unfortunately not in the PSU. My STRIX 3090 has the XOC bios and when overclocked, pulls 600W continuous and transient spikes up to 1000W so with the CPU overclock and GPU overclock (2130 core) I get random PSU trips so I decided to stop there.

But when I found out that I get basically the same performance with a lot less power and heat, I saved my OC profile then returned to stock settings and still get game clocks in the 5.8ish range. At 4k on a 3090, I don't think I need a 6Ghz CPU.

 

[StAndrew]

All of these motherboards don't have voltage control to cover both overvolt and undervolt simultaneously.

You are not rendering 24/7 like I am and are more likely playing games. In fact, I don't even need to do anything for heavy load rendering. The default BIOS setting is already at 40K. You undervolted it to get a 2.5% increase 41K with a lower temperature.

Says who? And what difference does it make? I'm just saying I think you have a lot more voltage tweaking to go. I ran my overclock at 5.7 all core for over 24 hours of R23 and barely broke 300W peak power and still was stable at 6.0-6.2GHz under light and medium load. I'm pretty sure you can bring that 350W power down a bit.

However, the CPU is designed to handle 100C just fine

So the headroom is meant for high voltage and high frequency at light loads.

This is where we're going to have to agree to disagree. I honestly don't think there is enough testing to validate that claim.

 

[StAndrew]

You have 5.7GHz in games instead. If you want 6Ghz all-core gaming then the LLC needs to be raised to the stage of overvolt instead.

SAYS WHO?

I already said your voltage is undervolted that won't be stable for 6GHz all-core light-load gaming. This is the difference.

Let me try one more time.

Overclocked, my gaming clocks were between 5.8 low, 5.9 - 6.0 average, and 6.1 peaks (and 6.2 light load/medium load).

I am NOT stable at 6.0 R23 all-core but I don't think you are either. Whats your point?

 

[StAndrew]

Says me of course. Games use all P-cores. You have a setting of 60, 60, 60, 60, 59, 58, 58, 57 then you have 5.7GHz in games. You should have a setting of 60x8. This is the point.

Wrong. I hit 5.7 in all core heavy load such as R23. Look back to what I said. My CPU boosts 200MHz over the overclock settings even though TVB is disabled. My game clocks are NOT 5.7, they are 6.0 with small drops to 5.9 and small peaks to 6.1. Look at my attachment. My clocks are sitting at 6.2 all day under light load.

You're saying I can't setup a V/F curve that allows the CPU to run at 5.7 heavy and 6.0 light load, yes? I disagree.

 

[StAndrew]

Your attachment picture is meaningless in desktop with no game to use all p-cores. In reality it is 5.7Ghz.
Better show the screenshot of an actual game.

Since you know all about how my computer clocks, you show me my screen shots. In fact, show me a game that loads 16 threads to 100%. I'm beginning to think you know how Intel Turbo Boost works...

 

[StAndrew]

As long as a game uses 8-Pcore you will have 5.7GHz. Don't fool yourself.

Good. Show me a game that uses 8 cores.

 

[StAndrew]

I'm not sure why the exposure, maybe its the Auto HDR feature but here is Warhammer II, my heaviest CPU intensive game.

 

[StAndrew]

Dango. Good temps.

I'm going to delid/relid with new IHS this week just because.

My own CBr23 5min temps with an H115i and a near-stock (55p/43p) all-core OC:

I may be selling this block soon if you want it. It's a 12th gen supercool direct die block and I just got a 13th gen block which I can hopefully install this weekend.

 

[StAndrew]

Just because you can do something, doesn't mean you should. But hey, if you just need this CPU to last until 14900K comes out, go for it Battlefield 2042 uses MORE than 8.

Well my games don't so I'm still not gaming at 5.7 and stable up to 6.1...
