Wah recently my Firefox browser was updated to mitigate the two vulnerability issues.

Seems to cause constant lagging in loading issues. I guess have to live with this performance hit until I upgrade my CPU again. :s22:

Haven't noticed any performance difference yet with my Ultrabook CPU leh

Because just synthetics for client users apparently

https://cloudblogs.microsoft.com/mi...-and-meltdown-mitigations-on-windows-systems/

Here is the summary of what we have found so far:

  • With Windows 10 on newer silicon (2016-era PCs with Skylake, Kabylake or newer CPU), benchmarks show single-digit slowdowns, but we don’t expect most users to notice a change because these percentages are reflected in milliseconds.
  • With Windows 10 on older silicon (2015-era PCs with Haswell or older CPU), some benchmarks show more significant slowdowns, and we expect that some users will notice a decrease in system performance.
  • With Windows 8 and Windows 7 on older silicon (2015-era PCs with Haswell or older CPU), we expect most users to notice a decrease in system performance.
  • Windows Server on any silicon, especially in any IO-intensive application, shows a more significant performance impact when you enable the mitigations to isolate untrusted code within a Windows Server instance. This is why you want to be careful to evaluate the risk of untrusted code for each Windows Server instance, and balance the security versus performance tradeoff for your environment.

    For context, on newer CPUs such as on Skylake and beyond, Intel has refined the instructions used to disable branch speculation to be more specific to indirect branches, reducing the overall performance penalty of the Spectre mitigation. Older versions of Windows have a larger performance impact because Windows 7 and Windows 8 have more user-kernel transitions because of legacy design decisions, such as all font rendering taking place in the kernel. We will publish data on benchmark performance in the weeks ahead.

MSI, one of the world leading motherboard developers, has been working swift on solutions ever since receiving a formal notice from Intel® stating that the current Intel® microcode version might be subject to recently identified security vulnerabilities.

To ensure any system powered by MSI Z370-series motherboards is operating securely, Intel® and MSI have been working around the clock to prepare updated microcode and release new BIOS updates, which will be available for download

...

Furthermore, MSI is preparing updates for its X299-series, 200-series, 100-series and X99-series motherboards. For these platforms, BIOS versions containing similar security patches are expected to be ready very soon. Keep an eye on the product pages to check for their availability.

The MS update to mitigate the vulnerabili f up the asus AI suite software so much so that I can no longer monitor nor control fan speed.

This is very bad.

GIGABYTE TECHNOLOGY Co. Ltd, a leading manufacturer of motherboards and graphics cards, has promptly implemented safety and precautionary measures aligned with Intel®’s response to safeguard customers against security vulnerabilities on systems utilizing Speculative Execution and indirect branch prediction.

The newly released BIOS updates from GIGABYTE integrate the latest Intel advised CPU Microcode versions to mitigate issues potentially caused by the security vulnerability. Customers who have purchased a GIGABYTE board are strongly recommended to visit the GIGABYTE official website immediately for the latest BIOS updates. Please refer to the following micro link for the list of available BIOS updates by models (currently offers updates for models that support 6th/7th/8th generation Intel® Core™ processors and X99/X299 platform): https://www.gigabyte.com/MicroSite/481/intel-sa-00088.html

asrock's on radio silence but i highly doubt my board will receive a microcode update :s13:

/also, it appears that my kernel got patched to 4.13.0-26 and that it doesnt like cinnamon desktop env (or smplayer.. or mpv... or a combination between these 3... *something something intel graphics driver*)
/and intel microcode to 3.20180108 :s13:

Can DIY yourself, I tried modding the bios to include microcode v.22h as a proof of concept and it worked. :s12:

There's reports of people getting WHEA errors when on microcode version v.23h so I haven't flashed that bios yet. :s12:

it's k. install the latest microcode can liao :s34:

as for the earlier issue (*cough* IME), i could flash in the patched firmware but it isnt recommended for B85 bah

so llst and either buy a H81 board or Ryzen 5 G bah :s34:
