I have Aorus Master X570 with Ryzen 9 3950X and separate graphics card (ASROCK Radeon RX 5500 XT Challenger D 8G in PCIe 4 16x slot)
I have installed 4x 32GB DDR4 corsair modules (VENGEANCE RGB PRO 64GB (2 x 32GB) DDR4 DRAM 3000MHz C15 Memory Kit) to it which makes 128 GB in total.
I have the latest BIOS (F11).
However I'm not able to use all 128 GB. My system only has ~126GB available, more than 2GB are reserved.
Is there some setting in BIOS i need to change to have the full capacity or RAM available? Is this somehow pre-allocated for some internal graphics (some ryzen do have internal GPU).
I'm using Linux (Kubuntu 20.04), here are the outputs from some relevant commands:

I executed memtest couple of times and the modules seems to be working fine. Also lshw shows correct parameters for them.

Lenovo motherboards soon? Legion branded motherboard spotted online
by Sayan Sen
A couple of motherboard images bearing the 'Legion' logo - the gaming brand of Lenovo - were spotted online by Weibo user 'WolStame'.
One of these is a comparison between the newer Blade 7000 motherboard with its predecessor highlighting the upgrades, while the other image is a close-up of the new model showcasing the Legion brand and the robust build of the region around the CPU socket.
The board appears to be equipped with most modern features expected of a decent mid-high-end motherboard nowadays. These include:
Four memory DIMM slots, 8+2 power delivery system, Heatsinks covering the VRMs, PCH and PCIe regions. 3x M.2 slots (Two for SSD, One for Network Card), 5.1 Channel Audio Output. USB-C interface
For those unaware, Lenovo sells pre-built gaming towers with the 'Blade' branding and the company, in fact, recently announced an update to its 7000 series with Intel Coffee Lake CPUs, the Intel Core i7-9700F to be precise. Hence, it's very likely that the firm was showing off the capabilities of its new Blade 7000 series motherboards compared to its previous offering. Though, the possibility of a standalone launch certainly remains as these look quite well-made and could surely appeal to most gamers.
Regardless, it's still interesting to learn the differences that Lenovo has made under the hood in the new Blade 7000 gaming tower.

I've set fast boot to be enabled, I've set the post screen to display for zero seconds.... it still shows for 3-5 seconds, my old mobo would almost instantaniously skip it (it would flash up for maybe 0.5s so you could still actually enter bios if required).
Any ideas on this?
Gigabyte 400-series Motherboards for Intel Comet Lake-S spotted at EEC
by Sayan Sen
In the last couple of years, competition for Intel in the desktop CPU space has been growing thanks to a resurgent AMD. The latter has adopted a tenacious strategy of adding more cores, which has also forced Intel to do the same, and at a pace much faster than the Santa Clara-headquartered firm was previously used to.
To combat the newfound competition, Intel is gearing up to refresh its desktop CPU and motherboard offerings with Comet Lake-S CPUs and 400-series chipset motherboards. The latter is now confirmed thanks to the listings of Gigabyte's upcoming models spotted in the Eurasian Economic Commission (EEC)'s database.
From the leak, it appears that Intel has slightly altered the naming scheme of the upcoming chipset variants. The _70 series which was previously prefixed by Z- is now led by the H- prefix. There is also the appearance of a new "Q-" prefix chipset model.
The names of the leaked models have been summarized below:
GIGABYTE 400 Series Motherboard models Z490 H470/Q470 B460 H410 Z490 Aorus Elite H470M DS3H B460M Aorus Pro H410M HD3 Z490 Gaming X H470M D3H B460M Gaming HD H410M H Z490M Gaming X H470 HD3 B460M Power H410M D2VX SI Z490M DS3H Q470M D3H B460M DS3H H410M DS2V Z490 D B460M D3H H410M DS2 Z490 UD B460M D3P H410M S2 B460M D3V H410M S2H B460 HD3 H410M S2P B460M D2VX SI H410M S2V B460M D2V H410M A H410 D3 H410N Pricing and availability of these are unknown at this point. It is rumored that the Comet Lake-S CPUs is launching sometime in Q1 2020 which leads us to believe that the motherboards should also come out around the same time frame.

Last night a thunderstorm hit very close to my home while I was using the computer. The light went off for a minute. After the thunderstorm I decided to turn the computer again. Everything booted fine with no errors. But the keyboard, mouse, and a xbox controller where dead with no signs of working even in bios. Naturally I thought that something should have failed. I connected the keyboard to another computer and it worked fine.
My computer monitor has usb ports. I connected the keyboard and mouse. And for my surprise they do work, checked for configuration but everything looks fine in the software side. Did some test and found that every USB port on my computer do transmit data. But lack of 5v power. I checked every power pin on the power supply and everything is good. A visual inspection show no burn, smoke, inflated, or blown up components.
Ethernet ports and sound works fine. I can't test other non USB 5v ports, because I don't have the correct cable or device. I don't care about those because I never use them.
I suppose that the USB power has a fuse or an internal regulator that could have failed. Can anyone had this kind of problem before. I got the tools to repair the motherboard. But want to know others opinions before messing up with the hardware.
