How do you test RAM OC speed?

Pretty much as the title says. CPU Z and prime 95 tests processor speed, is there a RAM equivalent?

Memtest at a guess and doesn't cpu-z show memory aswel?

If memory serves my correctly (no pun intended) there is a memory tab on
CPU-Z that shows how fast the memory is running.

This

It shows the NB speed aswel on the memory tab aswel as all the timings.

Ok. Will have to check again but IIRC when I looked last night I'm sure CPU Z memory tab showed 800MHz. This is the 1600MHz Samsung green RAM

800mhz is showing correctly then for DDR you double this value to find frequency. So its running at 1600mhz then.

dual channel mate -> 800x2=1600mhz

A gold star

Must try harder

Cheers peeps. For those in the know easy. For the poor blighters like me impossible! But heegh, now I know. Thanks for imparting your knowledge.

So to me that would suggest my RAM is not OC'd. It stays at 800MHz even with prime 95 running. The RAM shows 11-11-11-28

RAM speed doesn't go up and down like the processor speed can.

Whatever it says on the memory tab in CPU-Z is what it's running at (after you've doubled it).

1600MHz, 11-11-11-28 are the standard settings for the Samsung Green.

Have you actually changed settings in the BIOS to overclock the RAM?

I personally haven't. This is an OCUK pre built machine with OC level 4. (25% CPU OC and maximum attainable RAM speed). Hence my reason for purchasing Samsung green RAM.

I suggest you post in Customer Service and ask OcUK about it.

What is the rest of your system??? Maybe 1600mhz is the best effective speed for your system is it SB Based???

He has an i7-3770K and an Asus P8Z77-V.

I shall post in the customer service forum. Just wanted to find out what was going on first. Thanks for your help.
