Playing around with RAM overclocking. Best I can seem to accomplish is 4x8GB DDR4-4000 17-17-17-37-1T. All four of my sticks will individually do 15-15-15-35-1T at DDR4-4000, but attempting to boot with all of them results in random channels dropping out. Throwing voltage at VCCSA seems to help, but it's terribly unstable and doesn't seem worth it - for reference, DDR4-4000/17-17-17-37-1T requires 0.95V VCCSA - getting all four sticks to show up at 15-15-15-35-1T requires 1.2V VCCSA.

Clocking above DDR4-4000 doesn't work regardless of the timings I use.

This is on an X299 OC Formula

OC Formula is the best board for memory overclocking should be your memory controller so bad I have on Gaming k6 board up to 4200 cl15 1T with very low voltages 1 to 1.05v VCCSA

Now that I am not baking the CPU (post delid), I can run all core @ 4.4GHz 1.18v here's RB2.44 after 15 minutes (temps have stabilized here...

I was getting throttling before on 2-3 cores trying this with the same AIO:

what were you able to run before delid?

I could run all-core 4.4GHz at the same voltage, but not for long as 2-3 cores would thermal throttle - it was hugely temp limited...

I didn't get much tuning time because of that, just didn't make sense to push it since I knew it was going to run away...

Trying 4.5 now...

15m of RB2.44 passed - 4.5GHz all-core 1.18v.... (temps/volts right at the end):



CB R15 @ 4.5 looking nice too! thumb.gif


Guess its time for 4.6?
EDIT: yes... yes it is time for 4.6 (VCCIN raised to 1.8v Vcore to 1.21v - that peak power tho... blinksmiley.gif - see bottom of image 450W+):

Where do I read the current (default) cpu cache voltage?
Under what utility?
What do you guys recommend for a 3000 cache freq (manual mode)?

Been using SiV - seems reasonable so far.

~1.0-1.1v for 3GHz cache seems typical. Mine is not stable with 1.0 @ 3.0GHz, but I haven't tried to fine-tune down below 1.1v - SAT says 3.0GHz@1.1v is stable (1 hour).

Thanks
How do I expand it to get that screen you've posted above?
R you still testing the cache with aida & hci?

Click on the button labeled "Status" Not the most intuitive thing in the world, but a wealth of info and seems to be pretty well updated for system quirks.

Well, I can read something between 1.016-1.032 at default.




Should I start with 1.05v?
Aida64 cache & HCI still good for that?
