Uneven ram speeds

[LeonVennik]

The ram speeds and other info dont match up, both original from a HP ProBook 4530s, bios says both Samsung 1333Mhz ram

 

help me with this

They're both running at 1333MHz, but one stick is rated for 1600MHz while the other is 1333MHz. The 1600MHz stick is 3 years newer than the 1333MHz stick too, so I guess it was upgraded at some point?

[LeonVennik]

yeah, took one out from a wrecked up probook 4530s so it could go in my BlueBook (custom Wrapped)

 

thank you for seeing this btw

Ah, yeah that would be why. 

 

Both are running at 666MHz actual clock, which is 1333MHz DDR/effective clock. If you're wondering about the JEDEC specs, they're basically just telling you what settings the RAM will run at for different frequencies. 

 

EDIT: The important part is the memory tab, which shows what it is actually running at, while the SPD tab shows the specs for the memory rather than the current settings.

In a dual channel ram system the lowest speed will dictate the dual channel speed.

So the pc will use 667mhz for both ram.

The RAM here isn't running in dual channel, it's operating in single channel mode. 

 

If you mean having two sticks, then yeah, but that's something different from dual channel. 

[SupaKomputa]

well that's odd, just put it in dual channel mode.

[LeonVennik]

there is only one stick capable of dual chanel mode

Those sticks combined are capable for dual channel.

Dual in the screenshot means its Dual Ranks and the other one is Single Rank.

well i just tested, the slowe dim i think is dual mode, the fast one single, but i tested them seperately
