While I used to disable this feature, I’ve grown to love TVB Voltage Optimizations.

It’s a little known BIOS option with a big impact

When enabled, it makes the CPU lower its voltage depending on the temperature

So even if I set the P-cores to 1.4V for 5.8 GHz

In idle, the voltage is only 1.3V below 50C

But that shoots up to nearly 1.4V at 100C

Just published SkatterBencher #103: Core Ultra 5 250K Plus Overclocked to 5700 MHz

The Core Ultra 5 250K Plus is the second of the new Arrow Lake Refresh K-SKU processors I overclocked. The overclocking experience is not much different compared to the other Arrow Lake CPUs, though this particular sample had quite a satisfying amount of P-core headroom.

The story with Arrow Lake is one where essentially everything helps improve performance: P-cores, E-cores, data fabric, and memory. I didn’t squeeze this chip for all its worth and we’re still at 20% geomean performance speedup. That’s more than what Intel claimed Arrow Lake had over 14th gen Raptor Lake.

Highlights:
- 5.7G P-core clock
- +20% geomean performance speedup
- +40% LLM Performance speedup

As always, I try to keep things accessible and transparent for anyone interested in learning more about tuning.

Setting up the museum website enables me to easily share little historical overclocking gems like this one: the first 4 GHz CPU Frequency validation by πŸ‡―πŸ‡΅ Holicho with an Pentium 4 2.4 GHz.

Just published SkatterBencher #100: AMD Ryzen 9 9950X3D2 Overclocked to 5860 MHz with ASUS Republic of Gamers X870E motherboard and AIO cooling.

I love that AMD decided to go all out and deliver what enthusiasts have been asking for for a while: a dual-X3D product. It’s surprisingly fast in workloads like LocalScore and Y-Cruncher, and somehow, despite the massive L3 cache, also seems to benefit quite well from a high-speed memory subsystem.

Also, we take it for granted now that the X3Ds are overclockable but we must remember that wasn’t the case when the technology first came to market. We are lucky there’s engineers at AMD dedicated to delivering value to the DIY enthusiast market and ensuring not only the dual-X3D can be overclocked, but it comes with all the tuning tools available for every Ryzen 9000 CPU.

Highlights:
- >5.2G nT OCCT SSE Stress Test
- +13% geomean performance speedup
- +40% LLM & Y-Cruncher Performance speedup

As always, I try to keep things accessible and transparent for anyone interested in learning more about tuning.

With the right cooling, this 48-core Xeon is performance beast.

We can run light all-core workloads at 5 GHz.

Get over 500 GB/s bandwidth at DDR5-9600,

With half a terabyte of memory!

And even handling 1000 watts under load is no problem
