Can XMP run at undervolt ?

[Ray888]

Hi please guide me
I have corsair 3200mhz 16Gx2 1.35 xmp profile

I already try to reduce the ram voltage n training voltage to 1.25 at xmp still on
When i try with memtesthci it success
But the speed still at 3200 ? I dont know about this n when i see at CPU-Z the ram still at 1.35 3200mhz

1 . But in bios already 1.25V ran voltage
2. Can i undervolt to go for 1.2V ? down the VRM heat ? My VRM heat around 35-42C

My proc already undervolt n now run at 1.090V i7 7700K no turbo
Pack temp 30-42 in use max temp 55C

3. Maybe when undervolt ram will my cpu can go little undervolt again ?

4. when i see ram speed in bios
It 3001mhz 3200Mhz what the mean ? Even after i manually change the xmp force to 3200mhz still say like that

1. WHY are you doing this?

2. No, XMP is a specific group of settings including voltage. You cannot set your ram voltage lower and enable XMP it will return to the XMP setting. You need to manually configure all the settings on your ram to get it to run at a lower voltage.

Cooling the VRM n extend ram n Chipset life n i read some forum someone said undervolt ram can extend n prolong the life + stability when i want go little cpu volt to <1.080V
Is that true ?

Im not undervolt n on xmp
But in turning xmp on reboot then go down voltage n training voltage at ddr voltage

Unless you overclock the hell out of your parts running them nearly to their max temp all the time, Ram, CPUs, and Motherboards last nearly forever. Your hard drive, SSD, or GPU are WAY more likely to fail. Intel CPUs have something like a 0.5% failure rate. Your stuff will be obsolete way before it ever could fail.

So sure undervolting will make it last forever, but so would running it at stock levels and getting the full potential out of it.

Finally as I said XMP is a profile. You need to figure out the settings and manually enter all of them. And if you are undervolting its likely the ram you have will not work stably at its full clock speed.
