Windows 10: Partial Physical Address Leakage in Specific Intel Processors Advisory

Replace AMD Processor With Intel Processor.

Hi,

Thank you for writing to Microsoft Community Forums.

The AMD A4 is an AMD CPU and Intel i7 is an Intel CPU, so they neither use the same socket nor the same chipset. They are both physically and electronically incompatible. So, you may not be able to replace the AMD processor with an Intel processor.

The close to equivalent processor for Intel i7 would be AMD A10 APU because it has a way more powerful integrated graphics chip, better multi-threading support, and the mobile processor provides 4 cores where as Intel mobile processor only has 2 cores.

 

Windows 10 32 bit Physical Address Extension

Hi,

I would like to inform that: Physical Address Extension (PAE) is a processor feature that enables x86 processors to access more than 4 GB of physical memory on capable versions of Windows. Certain 32-bit versions of Windows Server running on x86-based systems
can use PAE to access up to 64 GB or 128 GB of physical memory, depending on the physical address size of the processor.

Windows automatically enables PAE if DEP is enabled on a computer that supports hardware-enabled DEP, or if the computer is configured for hot-add memory devices in memory ranges beyond 4 GB. If the computer does not support hardware-enabled DEP or is not
configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled.

For more information refer:

Also refer:

In answer to your question:

• PAE is supported only on the following 32-bit version of Windows
• Yes

Hope it helps. Let us know for further assistance on PAE, we will be happy to help you.

Thank you.

 

Intel Gives Core i3 and Core i5 Dual-Core Processors K0 Stepping Update

Intel is giving some existing 32 nm "Clarkdale" based Core i3 and Core i5 processors an update. The processors will transition to the new K0 stepping from the existing C2 stepping. The parts that will be made on the K0 silicon are Core i3 models 530 (new sSPEC: SLBX7), 540 (new sSPEC: SLBTD) and Core i5 models 650 (new sSPEC: SLBTJ), 660/661 (SLBTK/SLBTB), 670 (SLBTL). Newer and upcoming models such as the i3-550, i3-560, i5-665K, and i5-680 are already being built on the K0 stepping die. Motherboards will require a BIOS update to support the new K0 stepping processors.

The K0 stepping change includes the following highlights:

• New S-spec and MM numbers for the converting products
• Extended CPUID will change from 0x00020652 to 0x00020655
• Host RevID will change from 0x12 to 0x18
• K0 stepping package is pin compatible with C2 stepping package
• Adds Processor Context ID (PCID) support

The revised older SKUs that are built on K0 stepping will be market-available by October 16.
