Wow! 4.4

I just want to get to 4.0. I will try your setting. What is the DRAM timing control setting?

First get your OC stable then work on your RAM timings. Also always go with the lower rating on the ram then what it is rated at just so if you run into a problem you know it won't be the ram.

What are your 4.2 settings and voltage at 4.0 if you know it. Just curious how it compares to mine at 4.0.

I've never tried for 4.4 but may try it if they are similar.

Vcore is holding you back here I think. You're probably going to need at LEAST 1.3 for 4 on the 950. All the rest of the settings look good. You've clearly been doing some research-

I might lock in that QPI Link Data rate to basically a value of 36X bclock (6948), but really- everything looks pretty well done. Bump up that vcore and let us know how you make out?

Yeah just set it to auto for now and get your oc right. What BSOD code are you getting when it fails?

Just so you know also, my 950 liked the 19 multi better for some reason. It may be the board or the cpu. Not sure.
