Many thanx to “Raja@ASUS” for his input to this thread and especially for this guide………………….

Offset Voltage:

Reduced my second chips’ 5GHz Vcore in Prime Blend from about 1.49v to 1.44v using an offset of +0.100. I can use +0.060 to run 20+ LinX.
I know, it’s no record and doesn’t seem much on paper but……….. when every millivolt counts.

Just a few comments. I’m not making any statements…………….

I’m really happy with this MIVE board. The BIOS (1485 for me atm) setup is a bit tricky for this casual ocker to grasp but checking XS and "asusrog" forums enabled me to progress. I use “Load Extreme OC Profile” to take care of the repetitive key functions needed to start the overclocking process and the settings I need to change are not too mind warping (don’t mention the “Skews”). Monitoring different outputs with my DMM is a bonus as well.

A few posters (various threads) seem to have no luck getting their SB’s over 5GHz. I am certainly no expert but the 4 cpu’s I had access to all clocked past 5.3GHz (different batches and e-tailers) . I know that many others have had better cpu's but I’m wondering if it is the stability of supply at high current values that holds other ppl back. A good quality PSU with good reviews emphasizing the stability of the 3.33v, 5v, and 12v steady states and their ability to hold up under high current stress might be a factor. I’m not promoting any particular make but good reviews emphasizing stability at high cpu loads (plus other device loads) has got to be important.

I'm not sure lapping the cpu has much effect. Again, just an opinion, but I lapped a 5.4GHz wall cpu and the wall changed to................exactly the same, 5.4GHz. Temps seemed lower but the wall did not shift.

I have an SS to hand and SB stories with low temps are not overwhelming (look out Kitfit, for the tales of woe ) but I was wondering............

I know that this is the wrong thread for SS but my question relates to the "LN2 enable" and "Skew" inputs. Do I need to work on these settings with SS? If so, what are the important insights to get going in this area (besides putting the LN2 switch to "enable" of course )
