[Memory]Timings not as advertised...

I recently purchased additional memory and the manufacturer states the timings are 5-5-5-15

CPU-Z is telling me that they are actually 5-5-5-18

My other two sticks currently running along side the new ones are 5-5-5-15 and are reported correctly in CPU-Z.

What should I do?

Set the timings and voltages manually in the BIOS.
Also note that sometimes,CPU-Z reports the timings wrong.(So after you manually set the timings and voltages from the BIOS,use another software such as Everest to check them)

Set everything in bios- 5-5-5-15-20 and voltage to 1.9, even though it's supposed to be 2.0. My settings only go as high as 1.9 for some reason.

Everest and cpuz are reporting the same results.

One set of memory is at 5-5-5-15-21 1.8v

The other is 5-5-5-18-23 1.8v


These are two different manufacturers, PQI and Super Talent. I've read where mixing can cause issues.

Next I'll pull one set and see if the manual settings actually stick.


EDIT: Manual settings won't even allow me to post.

Not sure what to do now. Just leave it I guess :(  Seems to run like a champ even though.

So your system doesn't POST with either of the sticks installed simultaneously ?

Posts just fine with all four installed at the same time. It won't post if I go in and set the timings to factory specs.

Just to recap:

I just installed some additional memory and cpuz and everest are reporting different timings than the manufacturer.

The first set of memory, 2 sticks of Super Talent @ 5-5-5-15 (factory specs)

The second set of sticks are PQI @ 5-5-5-15 (factory specs)

In CPU-Z the Super Talent is showing 5-5-5-15-21
In CPU-Z the PQI is showing 5-5-5-18-23

Forcing the 5-5-5-15-20 in the bios only leads to an inability to post and a beep error.

Maybe because your RAMs are from different manufacture,CPU-Z and Everest don't show the right timings.
Anyway,run memtest for 4-8hrs and if it didn't report any errors,then your system is fine.
