memtest v2.11 Can't Support Tylersburg-EP Chipset ，the next version can join it?

Yes, but I need a CPU-Z dump of the platform.

Added to TODO list.

But handling NUMA on Nehalem-based CPU is a hard work.

It seems to me there is nothing special that is needed for NUMA. What _is_ needed is support for more than one memory controller, and support for empty memory controllers.

For example, if the first Nehalem memory controller is not present or not populated, then MemTest86 does not work. Take an Intel GreenCity motherboard with two CPU sockets, but install the CPU into socket 1 only. You will see that the bus number is xE not xF, where x is F, 7, or 3.

Similarly, an AMD based system with more than one memory controller, but with no memory in CPU 0, there will not be legitimate memory timing values for CPU 0.

About the tylersburg-ep, the cpu-z can not dump the spd value of memory module. I check the VID & DID, and the memtest code has the setting of "ICH10R". But the program still can not read the spd. The smbus control register(D31:F3) shows the smbus base address, but the spd could not be accessed and only shows the value "00". Could someone solve the problem, or any advice?

How many processors does your board support? If the board has two or more processor sockets, then there are two or more SMBus segments, which would normally be toggled with GPIO pins. The GPIO pin assignments differ from one board to another.

If your board is the Intel GreenCity board, then the GPIO pin assignments are 53, 52, and 49. If your board is the Supermicro replacement (X8DAI/3), the GPIO pins are 49 and 33.

My platform has 2 cpu slot which is made by Tyan. As you told above, could I modify memtest program to read the spd information? Two SMBus segments?How could I choose the SMbus segment by program?
Because I am not quiet understand the GPIO pin that you told,could it be accessed by software?
