And of course, I already mentioned the issue of older programs. Yet random I/O, depending on file sizes, can take a very strong hit in terms of performance on older CPUs. Serialized I/O, such as when running backups, is quite good when using the Ghost microcode. You all have no idea how bad the slowdown becomes when running such older programs. Moreover, “Ghost” also indicates all Intel CPU microcode which Intel released after December 2017 in order to mitigate Meltdown and Spectre, and all related CPU flaws.Īfter five days of stable testing, I finally got fed up with the extremely poor performance of the August Intel Ghostbusting microcode when running older non-multithreading capable programs on my Win7 test computer.

I both coin and in the future will refer to all Intel Meltdown and Spectre mitigating CPU microcode as “Ghost” microcode, since if you read about all of these vulnerabilities which are related to the flawed CPU speculative execution and about how POC code works, you will realize that my Ghost acronym is quite appropriate. The VMware Fling allowed me to do this, instead of having to create and flash a custom modded BIOS flash file for my out of warranty MSI motherboard’s BIOS in order to implement Intel’s latest August Ghost microcode. I was doing so for the past five days by using the VMware utility which allowed me to use Intel’s latest August uCode for my I5 Haswell CPU. In another post, I mentioned that I have been testing Intel’s latest Ghost microcodes on my production Win7 圆4 machine. Maybe Anandtech’s been drinking too much whiskey lately? Or is the DeLorean now powered by Mike’s Harder Lemonade?!

Still not sure how to obtain the microcode.Īlso, the current PDF STILL doesn’t list the mystery Lakes… “Amber”, “Cascade” & “Whiskey”. My Ivy Bridge processor on my ASUS X55A laptop has a “New Production MCU Rev” of 0x20 & my 0x1F is now “Pre-Mitigation Production MCU”. UPDATE: I followed tweetstorm to (AKA PhotM on the Lounge) & found a more current PDF dated Aug. If anyone knows if there’s a more recent PDF from Intel than Apr. Has Anandtech taken their DeLorean time machine 5 months into the future & these are Meltdown/Spectre fixes for Win10 1809?! Anandtech claims “Amber” & “Whiskey” are based on Kaby Lake, so do the Kaby Lake fixes cover them, or are these NEW CPUID’s? “Cascade” might be based on Coffee Lake.

There are NO mentions of “Amber”, “Cascade” or “Whiskey” Lakes on the PDF. Here’s the most recent Intel Microcode Revision Guidance PDF (Apr.
