I have had this PC for quite a while now.
I had Original Dual RAM of 16GB before. 2x 8GB
Type DDR3
Size 8192 MBytes
Manufacturer Corsair
Max Bandwidth PC3-10700 (667 MHz)
Part Number CMX16GX3M2A1600C11
Serial Number 00000386
Week/year 23 / 12
SPD Ext. XMP RUNNING as XMP-1598 799 MHz 11.0 11 11 30 1.500 V

I Bought another 2x 8GB 16Gb now as 32GB before Xmas 2020 and it is run as this--
Type DDR3
Size 8192 MBytes
Manufacturer Corsair
Max Bandwidth PC3-10700 (667 MHz)
Part Number CMX8GX3M1A1600C11
SPD Ext. XMP RUNNING AS XMP-1600 800 MHz 11.0 11 11 30 1.500 V

Why is my old ram at XMP-1598 And the New Ram at XMP-1600...
THANKS.

What does CPU-Z say for DRAM frequency?

Different RAM by looks of part no.s?
I have got 4 sticks of Corsair LPX, identical part no.s, but two are made by Samsung, two by Micron.... I used CPU-Z to find this out.

Sorry I'm late back. Been busy... Here is my Original first Dual Ram---CMX8GX3M1A 1600 (667MHz)
New Sticks are---CMX16GX3M1A 1600 C11 (667MHz)
Can't show you image as they on my Hard Drive and you don't allow that. (silly really)
Not sure why old ram says 8 with Dual RAM to 16GB WHILST New says 16 with two 8gb sticks. What is the difference please.
I put in Exact same as the old and ordered and got the 16. CHEERS.
