Can't go more than 1800MHz FCLK so I optimize my RAM timing a bit. Generic B-die still can perform well, I can't use Ryzen DRAM calculator settings so I manually tweak the timing one by one. This is with Geardown disabled.

Here's my bench after new ram install!

4133 c19-21-21 trfc550 @ 4133 c16-16-16-31 trfc 400
vccio at 1.1v vccsa at 1.2v
ring 42x,can't go any higher on 10500

still can't go lower than 41ns.any tips ?

When I had that initial play the day I installed and ran mine at 4000mhz at CL16 (1.4v Dram) with VCCIO and SA voltage at 1.20 they would boot me into windows but fail 15 minutes into a stress test, I increased both voltages slightly (I think 1.23v) and they were fine, give that a try and see if you can get some more out of them although personally I would not go above 1.25v for everyday use.... looking forward to a bit more time to tweak again!

Im getting 4133 c16 stable at 1.1 vccio and 1.2 vccsa.
including memory stress test.
weird to see a locked i5 requires lower imc voltage than K,but that's possible.

wanna see what happens with 4000 c15
 
It could have been something else causing the instability but if I remember correctly I was on 1t on that run so perhaps it was that but the extra voltage seemed to help.

Edit: I like to see what I can get on 1.4v, prefer not to go higher although I know these kits will do 4500mhz at CL18 on around 1.45.
 
what happens with 4000 c15 is no boot is what happens.I know even some 4400 bins cant do 4000 c15.

still,4133 c16-16-16 is remarkable for a kit this price.

I think 1.45v is fine especially with lots of airflow going on.with a clc I'm not sure.

Mine didnt even get warm at 1.45v (3 x 140mm front fans) on the only run I used that voltage on which was at 4400 cl18.

Edit: Just running them at 4133 17-17-17 currently until I tweak again at 1.4v with SA at 1.2 and VCCIO at 1.18.
 
mine are 3x120 with lots of pressure,the sticks are getting plenty of air.
seems like I'll settle for 41ns at 4133 16-16-16 trfc 400, no need to push further cuz voltages would be too high for my taste.
and yeah,the heatsinks are cool even after a stress test on a hot day


I'm such a dummy.
I tried cr1 on 4133 c16 and didn't post,then wondered why my previous settings won't work again.of course I forgot to set cr back to 2.

may wanna tinker with cr1 later,I got dmc5 to start atm

How can I achieve latency under 40ns?
I have 2x8 F4-3200C14D-16GVK which I could push to 3600 cl14-14-14-34 ct1 rtfc 350 tfaw 28 1.5v 1.2 VCCSA/VCCIO but after bios update i can no more :c
Right now I am using 4000cl16-16-16-36 ct2 with same voltage and sa/io but now trfc is 374 and tfaw is 28

What I can improve to break the barrier?

I can't do lower than 41 with 4133 c16
stuck at 41.5

I believe you would under 40.

Mine on the right, yours on the left. My timings.

Nice overclock, how high have you have that kit?
Click to expand...

Ran it forever at 4000-16-17-17-36-1T@1.425v /w 1.15v IO/SA. Can sometimes boot at 4266-17-18-18-36-2T@1.45v /w 1.25v IO/SA and tested for about 15 minutes in RAM Test for about 1000% coverage, but reboots don't always post. I know my mobo has done 4266 at that speed and timing before on an 8700K and 3600C16 kit, so it's likely flaking out with my 9900K. I've tried 1.5v+ and up to 1.4v on IO/SA for 4266+, but nothing boots.

The 4133-16-17-17-36-2T profile is achieved at 1.45v /w 1.2 IO/SA and passed 1200% coverage in HCI MemTest Pro. 2T didn't penalize it too bad; -0.4ns latency and +2GB/s copy. My board doesn't have any RTL IO-L controls, but performance could be better if they could be tweaked somehow:

At stock speeds with a 5.2GHz. boost when it needs to.
I like it.
