Memory controller MSR:
static float getNHMmultiplier(void)
{
unsigned int msr_lo, msr_hi;
float coef;
/* Find multiplier (by MSR) */
/* First, check if Flexible Ratio is Enabled */
rdmsr(0x194, msr_lo, msr_hi);
if((msr_lo >> 16) & 1){
coef = (msr_lo >> 8) & 0xFF;
} else {
rdmsr(0xCE, msr_lo, msr_hi);
coef = (msr_lo >> 8) & 0xFF;
}
return coef;
}
Looks like we need to emulate it since memtest only looks at the cpuid
to detect an integrated memory controller. What does this return for you?
dd if=/dev/cpu/0/msr skip=$((0x194)) bs=8 count=1 | xxd
dd if=/dev/cpu/0/msr skip=$((0xCE)) bs=8 count=1 | xxd
