Configuration and frequencies respected:
Here’s the configuration I’ll be using to test this ASRock Taichi Z890 OCF. For the publication of these tests, I’ve used the latest BIOS available on the motherboard’s product page. For this test, we decided to use the largest processor in the range, the Core Ultra 9 285K, as well as three different memory kits. They differ from each other in the type of memory they carry, but we’ll talk more about this in the overclockingtests.
- Intel motherboard: ASRock Taichi Z890 OCF (BIOS OC29)
- Processor: Intel Core Ultra 9 285K
- Memory: 2 x 24 GB Teamgroup 8200 MT/s CL38
- Graphics card: NVIDIA RTX 4070 SUPER
- Cooling system: Waterblock Optimus Signature V3 Intel and Alphacool Chiller Eiszeit
- Power supply: be quiet! Dark Power 13 1000w
- Operating system: Windows 11 64-bit 24H
Here we go for this first series of tests.
Frequencies respected?
As with every new processor test, our first concern is to check whether the advertised frequencies are actually achieved. To do this, we’re going to use the Cinebench R23 benchmark. Two scenarios will be used: a single-core benchmark and a multi-core benchmark. The idea is to be able to judge the frequencies achieved and compare them with what Intel has announced in its slides.
It’s worth remembering that the Boost frequency in the bench is different for each processor. As Intel points out, Max Turbo frequency refers to the maximum frequency attainable by one of the processor cores running a single-core workload. This frequency varies according to several factors: the load, the cooling system and therefore the temperature of your processor. This is a concept to keep in mind.
The first step is to select the ” Intel Default Mode ” profile in the BIOS, and activate the XMP I profile. We’ll start by using Intel’s recommendations for this frequency test.
Test with Core Ultra 9 285K :
Here we go with the beefier of the two processors we received, the Core Ultra 9 285K. As you can see, we’ve opened several windows to check frequencies, temperatures, working cores and power consumption. We’ll start with a single-core run of Cinebench R23.
We can see that two Performance cores are working alternately, core #0 and core #1, and that they easily reach a frequency of 5700 MHz, as indicated by Intel on its slides. Let’s see what happens when we launch a Multi Core run.
All cores come into action. Lion Cove P-Cores reach 5400 MHz and Skymont E-Cores 4600 MHz. Now let’s get on with our various tests.
