Slew rate is a new topic just brought to light, but in hindsight a fundamental characteristic to be expected. The first quote suggests that there is a risk with the present LLC of increasing computation load faster than the LLC slew rate and hence having a period of potential instability (if LLC were used to achieve stability). This risk is reinforced by the next to last sentence of the first quote. The second quote implies to me that the LLC always achieves sufficient slew rate. So where are we in probability of insufficient slew?

Believe he stated approximately 50 microseconds for slew rate; always implies 100%. Gotta love Raja's replies thumb.gif

No, that was the duration of the overshoot. Different topic.

Just tried another go at a somewhat stable 4 GHz OC but have given up again for the time being. But while drop is currently discussed: with an offset of +0.1175V (-> 1.4675V) it drops below 1.39V on load.

indeed it does. 1.45v with for me brings it down to 1.38ish under load.

5 times fast go. I get stumped at scope->micro

@Raja and Elmore,
My C6H is running great, everyday since March 2nd, been having a great time playing with the new firmwares and tweaking settings. I know this thread is full of people having problems or questions, just wanted to say thanks and we all appreciate the work you guys put in.

Btw thanks to Shamino also!!

Thank Elmor and Shamino. Yours truly doesn't do much. I purposely held off getting this platform early. Waiting for some memory stuff to be opened off before I get my rocks off.

I cant pass IBT (max) at 4ghz all the way up to 1.46 AT LOAD mad.gif

- Aida64 Memory stability test with and without cpu stress test
- 2 hours of gaming on mass effect andromeda

Prime95 and Aida64 have been running for 15-30min since I am not comfortable putting such loads for long periods, so it might not be stable as some people here define it. But no errors what so ever for me.

No DOCP, only ram multiplier. Note though that I need 1.4V in my sticks otherwise Prime95 blend crashes the system and Aida64 gives me errors.

Seems stable enough! Mine would crash 5-10 seconds after starting IBT. Would you mind sharing your exact settings for anything related to your CPU & RAM so I can try and replicate your results? Before I could boot with 3200, now I'm struggling to even get that going frown.gif

Not too encouraging but I thought my "premium" 1800X could manage a bit better tongue.gif
