SPECTRE and MELTDOWN: Bug rocks Intel / ARM CPUs

[segfaulted]

Kinda glad I bought AMD this round. For those who don't know there is a new bug affecting just about every SKU from Intel made in the last .. ohh.. _DECADE_ or so. It's actually worse then F00F or FDIV. Only mitigation appears to castrate the CPU upward of 30%! (depending on processes).

Can Asus confirm AMD and more importantly for me, this or any AMD motherboard are not affected? If so, will there be RMAs?

Fun fact, Intel's CEO dumped stock back in November before they started issuing gags on people from even talking about it.

It still has the older 1203 bios issued in back in January.

And here is a new list of bioses only for the server editions expected to be released after April 9th

the H97i-plus now has a Bios update.

[hitthenorth]

I have a Z97-PRO GAMER board. I notice there are now lots of Z97 boards with BIOS 3503 available, apart from this one.

This is what I received from ASUS support. Just wondered if anyone else had managed to get any further information:


Thank you for contacting ASUS Support.

I am very sorry to hear about the problems you are having.

My name is Arsen and it would be my pleasure to help you solve the issue the best way I can.

Unfortunately, there is no concrete release dates for your motherboard.

One way to protect your machine from the Intel CPU vulnerabilities is to keep your Windows up to date, as Microsoft is releasing fixes as well.

ASUS and Intel are working hard on providing fixes for the Spectre/Meltdown, but BIOS update sometimes need a lot of time for testing and debugging.

Furthermore, it is recommended to keep you Windows up to date, as some fixes are provided by Microsoft.

I apologize for the inconvenience caused.

If you have any further question feel free to contact us again.

Kind regards,
Arsen_N
