I bought from them last year. The delivery is a bit expensive but can be amortised with more equipment ;) They have also collected UK VAT directly and Royal mail did not double charge me which is very nice of them.

All 15 gone in 1 day. You guys are monsters :P Back onto 25G for me

My ebay saved search is "apc (ap7722, ap7723, su042, su043, su044, su045, ap4422, ap4423)" I would not recommend the super old "su" models because the newer ones often get mis-priced to super low price anyway.

I was on a similar boat not too long ago and found that used APC ATS are not that expensive on eBay here in the UK. (Often <£100) If lucky, you can get one with network management and current monitoring. I basically ditched my UPS and use the ATS to switch between the inverter and the mains...

Non-ECC UDIMMs work fine but you cannot mix with other types. Though ECC RDIMMs are sometimes cheaper second hand.

I guess this is an ongoing investigation or the US is already engaged in equally dirty counter-measures, so they cannot officially disclose what they know. I wouldn't be surprised if the NSA learned a trick or two and is actively using it against other counties. As for the average Joe (not)...

I am security paranoid, so I am more inclined to believe it is true. I think the new article clarified a few things: 1. They stood by their claim that there are chips embedded in the motherboard PCB targeted at certain organisations. This is not as hard to pull off as people think. Just look at...

Spent all night reading through the Akamai board thread. I am very intrigued by it. I am interested in the Mikrotik as well (even though I probably shouldn't. Already spent too much on gear during lockdown....) Could you DM me with the details of payment? Also, mind telling me which platform...

Could also be power or signal interference. Most motherboards provide a way to read out the input voltage levels. The 12V and 5V are hopefully on the same bus as the one feeding the drives, so you can do a continuous log of those to correlate. Interference should cause command errors which...

I recently bought a working Datto NAS with the Gigabyte board and managed to get it into the no boot state by flashing the MB10-DS4 BIOS, i.e. video signal dies after the BMC initialisation screen (06). Fortunately, the backup BIOS was working on my board: I changed the undocumented jumper...

To get infiniband to work, you will need a fabric manager and an infinite amount of time to set the whole network up...

I have a feeling the original PCI-X slot was via a bus adapter chip anyways, so this is just returning it to the original format :)

How about a PCI-X to PCI-E adapter, e.g. PCI-X to PCIe Adapter - x16/x8/x4/x1 | StarTech.com You might want to check the topology of your mobo first to make sure you actually have enough bandwidth with so many devices plugged-in.

The last time I looked at it, there's a Chinese Thunderbolt board (single PCB) with a PCIe 3.0 x4 slot on the side and can be had for about 1000 RMB. You can see it being used as part of this Thunderbolt NVMe adapter. However, I don't think you can get that kind of price outside China. Coupled...

Did anyone notice any memory bandwidth problem with the 2018 firmware? On UserBenchmark.com, I can see several results with more than 6GB/s multi-core, but I only managed to achieve 3.4GB. I have upgraded the machine to the latest firmware and installed two sticks (which limits it to 1333MHz)...
