Intel Skylake bug causes PCs to freeze during complex workloads

Quote:
Intel has confirmed that its Skylake processors suffer from a bug that can cause a system to freeze when performing complex workloads. Discovered by mathematicians at the Great Internet Mersenne Prime Search (GIMPS), the bug occurs when using the GIMPS Prime95 application to find Mersenne primes.

Update: We've been informed that the bug was reportedly discovered and tested by the the community at hardwareluxx.de before being passed onto GIMPS, which conducted further testing. Both groups passed their findings onto Intel.

"Intel has identified an issue that potentially affects the 6th Gen Intel Core family of products. This issue only occurs under certain complex workload conditions, like those that may be encountered when running applications like Prime95. In those cases, the processor may hang or cause unpredictable system behaviour."

Intel has developed a fix, and is working with hardware partners to distribute it via a BIOS update.

No reason has been given as to why the bug occurs, but it's confirmed to affect both Linux and Windows-based systems. Prime95, which has historically been used to benchmark and stress-test computers, uses Fast Fourier Transforms to multiply extremely large numbers. A particular exponent size, 14,942,209, has been found to cause the system crashes...

Yea quad core alone is pretty anticlimactic :/
Unless Intel comes out with a 6 or 8 core I'd just assume stay with x99 boards and get another rather than z170's.

Yeah, I couldn't possibly use that processor.
I'm all day raising numbers to the 14,942,209 power.

Intel better get busy fixing Skylake

Quote:
For current PC owners, the detail to note is that Intel's current, sixth generation processors, known as Skylake, are the first that won't support either of the older versions of Windows. (Intel and Microsoft say that the platform and Windows 10 were designed for each other.) Microsoft is phasing in the policy now.
