Looks like it may be surprisingly straightforward to brick one among AMD’s finest gaming CPUs, even in the event you’re knowledgeable overclocking YouTuber. The world now has one much less AMD Ryzen 9 7950X3D (opens in new tab) after a slight voltage tweak above simply 1.35V.
Roman Hartung, aka der8auer, just lately took a visit to Taiwan to go to the Asus testing labs. There he determined to place some CPUs to the check however, because it seems, even in terms of fanatic grade CPUs akin to the newest X3D chip the previous saying stands: Simply because you’ll be able to, does not imply you must.
Truly, with AMD’s most interesting gaming chip, it appears you actually actually should not.
One of many nice issues about AMD’s Ryzen 7000-series CPUs (opens in new tab), is that it has been made tremendous straightforward to overclock in Home windows utilizing PBO 2 and Curve Optimizer. There nonetheless stays the choice to overclock your chip within the BIOS, nevertheless, the place chances are you’ll be introduced with the choice to push the voltage all the way in which as much as 2.5V. Eep.
So, alongside another testing, Hartung set about pushing the voltages of a Ryzen 9 7950X3D Asus had lent him. A lot to his dismay, all did not go to plan (opens in new tab) (through HardwareLuxx (opens in new tab)).
He first examined the waters by babystepping the voltage as much as 1.35V. And whereas it was essential to run and seize a liquid nitrogen cooler to maintain it between 85°C and 90°C, Hartung nonetheless determined to push issues additional.
He noticed the hazard, and he did it anyway.
The second the CPU hit 1.5V, all the things went out the window. The motherboard threw up a 00 error code, and regardless of his finest efforts, sadly it seemed like nothing could possibly be completed to save lots of the CPU.
It was clear the Ryzen 9 7950X3D had been fried even earlier than the CPU got here beneath load. And whereas Hartung himself admits it might simply be dangerous luck on his half, since not many excessive exams have come out for AMD’s new tremendous high-end addition to the Ryzen household, HardwareLuxx has issued a warning to customers in case anybody decides to push the voltage simply because the choice is there.
He has spoken to each AMD and Asus and been informed the chips weren’t meant to be allowed to run with such a excessive VCore ranking. He additionally says that “Asus will most likely restrict the max handbook voltage to 1.35V,” which is able to probably be completed through BIOS updates.
Throughout his journey, Hartung additionally had an opportunity to take a look at the $6,000 Intel Xeon W9 3495X chip. We have already reported on der8auer showing off the 56-core Intel chip (opens in new tab) at inventory speeds of 4.2GHz at dwelling, however he was assured then he might push it additional in Asus’ labs.
“I really thought that 4.4GHz or 4.5GHz needs to be completely straightforward, however that was not the case”, says Hartung concerning the Sapphire Rapids CPU (machine translated). That stated, he did handle to beat 4.7GHz on all 56 cores regardless of a number of crashes in Cinebench R23 owing to points with the enter voltage. That translated to round 114,000 factors, and actually reveals what these fanatic CPUs are able to when paired with simply an AIO watercooler.
With a liquid nitrogen cooling resolution, Hartung was capable of push the CPU as much as 2.5GHz and obtain a smashing 125,000 factors in Cinebench R23—a brand new report, actually.
Purple group fans could also be dissatisfied that they don’t seem to be going to have the ability to push their CPU voltages as much as these sorts of heights, however at the least we will relaxation assured that BIOS are more likely to be up to date to cease folks going past 1.35V. Nobody needs to seek out out they’ve by accident fried their monster CPU in a flight of overvolting fancy.
Solely you’ll be able to forestall CPU fires.
