Other news
As you can see all the big crunchers are off. Its summer in Sydney so it can get hot. While I have air conditioning I won't use it to cool the farm, I would rather turn the farm off. Not only is this better for the environment but it also saves my electricity bill.


Intel ARC
I had a quick look at the Intel ARC A770 but decided not to get one. The Linux support for them hasn't landed in Debian yet and performance is about the same as the RTX 3060 Ti, which I already use. To do a firmware update one has to use the Intel Management Engine, which of course is only available on Intel based motherboards. Lastly BOINC and the BOINC-based projects don't currently support them. This should improve over time but I think its too early to get one.

Ryzen 7000 availability
I priced an upgrade for my Ryzen 5900X machines. I would need a new CPU (Ryzen 7900X) at $949, Noctua NH-U12A cooler at $199, ASUS X670-P motherboard at $499 and lastly 64GB of DDR5-5600 memory at $599. Giving a total of $2,246 in AUD.

I would aim for faster memory as the sweet spot for the Ryzen 7900X is 6GHz and that would cost more of course, assuming I could even find it. Oh and then there are NVMe drives.

As I see it we aren't quite there yet. DDR5 memory is too expensive, not much faster than DDR4 and in too small capacities. You can't even get PCIe gen 5 NVMe drives at the moment. Its going to take a while for the 6.0 kernel to get into a stable Linux release giving the necessary driver support. I think I will have to wait a bit longer.

Bill shock
I've been limiting the larger crunchers from use to keep the electricity bill under control. At the moment its been the Pi's running 24/7 with bursts of activity from the x64 machines on weekends.


RTX 4090 announced
Nvidia announced their Ada Lovelace architecture high-end graphics cards (RTX 4090 and 4080). They can use up to 600 watts, so I won't be looking at them. I currently have a number of RTX 3060 Ti cards but if Nvidia keep increasing power consumption I will move to their lower powered models. They haven't announced the rest of the range so I don't expect to be upgrading any time soon, besides the existing Ampere architecture cards are now being discounted quite heaviliy.


Other news
I'm still waiting for AMD Zen 4 to be available at the retailers so I can work out how much its going to cost to upgrade the Ryzen 5900X machines. Given the price of DDR5 memory at the moment I may wait a while for prices to drop.

Other news
There hasn't been any work from Rosetta@home so the Ryzen 5900X's have been off. I had the Altra running for a couple of hours on weekends doing Einstein BRP4 work.

The Raspberry Pis have doubled with an additional BitScope Edge Cluster 12 being added.
