help in oc ram

[dfsgsfa]

i have no success in any clock over 3000mhz, 

corsair veng 3000mhz cl15 8gb x2 as pix below.

asus b350F, ryzen 1700

 

in bios, whats the diff in docp and docp standard?

ryzen cant use cl in odd numbers? cl15 will be tuned to cl16?

 

tried following dram calculator but too many blanks in bios... and no post

 

any tips?

You seem to have 8 gigabit Hynix AFR, which isn't the best choice for Ryzen but 3200MHz might work if you got the timings right. Is it a 3000MHz XMP kit? That said first gen Ryzen doesn't mem clock great, so 3000MHz might be all you get out of it.

can you suggest some safe timing?

i have no way knowing if the b350 is limiting or ram itself...

Checking with some friends who know more about Ryzen RAM overclocking, they don't think its likely to clock much higher. It's just the combination of CPU's IMC and RAM. TImings won't damage your hardware if they're not right, it'll just not boot or crash but voltages certainly can damage stuff. There is a programme that can try to caculate what timings are needed, here is what it thinks will work, I can't say for certain if those timings will work however. Worth a shot, this is for 3200MHz.

do i need to follow all these data input?

coz in asus bios there are some fields not match the calculator. 

i see people just change the 1st 5 item and leave the rest.

the secondart and tertiary timings can sometimes be important the key to a good overclock, I would say input all the ones that you can, it might help.

Does your B350-F BIOS have the 'Gear Down Mode' setting?

That is one feature / setting that locks the DRAM timings to even-numbered timings.

Not sure if it was available on 1st Generation Ryzen, though.

 

The ASUS BIOS should have the settings, but could be listed / named differently.

 

The quick-and-dirty would be to the change the primary timings (e.g. the first 5 items).

If you really want to fine-tune the DRAM timings, you drill down to the secondary and tertiary timings, too.

is it good or bad to have this?

It helps with getting RAM stable, but increases your latency...by one timing.

E.g. CL15 gets rounded up to CL16

 

If you have the option in your B350-F BIOS, you can experiment with turning it on / off.

Turning it off would allow yo to run odd-numbered timings.
