The motherboard manufacturers will update the CPU firmware via a BIOS
update. There are other ways of patching them as well such as using the
intel-microcode package under Debian.
The Intel CPUs have another security issue referred to as MDS or more
commonly known as Zombieload. The AMD machines don't have this particular
issue but are doing updates to support the 3rd generation Ryzen CPUs
even on older motherboards. I took the opportunity to update all the
We got a bit of a cold snap in the weather so the two machines with GTX
1660 Ti cards have been running 24/7. This has greatly improved their
I resurrected my Milkyway@home account, which I haven't used since 2012
and did a burst of GPU work for them. Their GPU app is written in OpenCL
and so is slower on Nvidia cards. The Milkyway simulations took slightly
under 4 minutes to complete on the GTX 1660 Ti.
At Computex 2019 (last week) AMD announced 5 of their 3rd generation
Ryzen CPUs. The official specs of these CPUs were somewhat different to
the leaks on the internet. We're expecting more official announcements
on the 7th of July as that is the release date. Only another 5 weeks to
At the moment I am looking at ASUS X570-Pro motherboards with DDR4 3200MHz
memory, but I am not sure how much memory because that depends on how
many cores they have. Which CPU they'll get is undecided until the rest
of the Ryzen line-up is officially announced. I will swap all 4 machines
out with the exception of reusing the GPUs so that will mean new cases,
power supplies, CPU cooler and NVMe SSD's to replace the hard disks.
The Ryzen 1700's that I currently use are 65 watts and have 8 cores/16
threads. For a GPU cruncher I was hoping for a lower wattage CPU, probably
with a lower core count. The X570 chipset uses 15 watts so that will eat
any power saved.
