I have a couple questions about overclocking on the Sr2. I want to preface with the fact that I am not only new to using the sr2 but fairy new overclocking in general so I apologize if I do something cringe worthy.
 
The problem I am having is that I can't get my bclk value to change, it is stuck at 155 and I can't figure out why. From what I have read online it my be related to my ram limitations but I wanted to check here before I change anything.
 
Some information that my help, I am currently running:

• two of the x5690 at about 4.03Ghz (155x26) 1.300V
• 48gb of ram (12x4gb) I believe it is all samsung but I may be wrong
• I am air cooling

 
A side question I have is should I even worry about going higher on the OC? My temps are okay for now but would pushing the OC a little more make a significant change in temps?
 
If there is any additional info I should provide please let me know and I will try to post it as soon as I can. Thanks for the help!

 Hallo ! 
here you can read a lot of overclocking the SR-2.
scroll down to  

OC SR-2 u need Watercooling for cpus

 
Thanks! That is a big help.
 
A few hours after making this post I figured out what one of my problems was, I accidentally had the Dummy OC setting enabled, which is embarrassing and ironic haha. I am still bad at ocing but that post you sent will be a big help even without the first images working thank you for sharing that.
 
I would love to do something with glass tubing to watercool this system but I will have to save some more pennies before I do that, for now the two noctua coolers I am using do a decent job
