Once my CPU is maxed out, how do I proceed to speed up my RAM?

[ahthurungnone]

I am finalizing my settings on OCing my Phenom II 555 over 4.0Ghz (using a MSI 890FX-GD70), once this is set and stable how should I proceed to speed up the RAM? I have Black Edition OCZ ram, so it should be able to be OC'd as well.

Any specific instructions would be best. Thanks.

What speed? 1333, 1600...

Ok, so I checked my memory with cpu-z, and now I am completely confused. CPU-Z says I am running 533Mhz (x2 obviously) at 7-7-7-16, but I purchased 1600Mhz as follows...

Go to the BIOS, in advance features, look for the option "FSB/RAM ratio" and change it to 1:4, below you can see 1600MHz right?

 

[ahthurungnone]

Yep, that did it. However, my latencies are not what the mfg recommends. I am currently running 9-11-11-24 and OCZ recommends 8-8-8-24. Should I change it?

 

[saint19]

Yeah, go to advance DRAM configuration and change it to the recommended settings.

 

[ahthurungnone]

I have no idea how to alter the latencies. Help!

 

[saint19]

Sure, I'm here for help you.

Go to your BIOS, in Green power look for "Advance DRAM configuration". There you only need change this:

1- DRAM Timing mode: Both
2- CAS Latency: 8
3- tRCD: 8
4- tRP: 8
5- tRAS: 24

The other options goes in Auto. Don't forget change the voltage to 1.65V.
