ASRock X470D4U - No XMP settings, maxes out at 3000Hz memory clock?

[Gio]

My new build is based on ASRock X470D4U and 64GB DDR4 3600Hz memory, it looks like BIOS overclock settings don't show speeds above 3000Mhz - anyone have any idea how I can get 3600Hz out of this board?

My memory supports 3600Hz = G.Skill RipJaws V Series 64GB (2 x 32GB) 288-Pin SDRAM DDR4 3600 (PC4-28800) CL18-22-22-42 1.35V Dual Channel Desktop Memory Model F4-3600C18D-64GVK (Amazon.com: G.Skill RipJaws V Series 64GB (2 x 32GB) 288-Pin SDRAM DDR4 3600 (PC4-28800) CL18-22-22-42 1.35V Dual Channel Desktop Memory Model F4-3600C18D-64GVK : Electronics)

There is no XMP profile on BIOS for this - I am running P3.50 BIOS as recommended on their support page for AMD 3700X CPUs.



and these are the other memory overclock options - I don't think I will be able to reach 3600Mhz (stock for this ram) when the bios max is 3k, even if I changed any of the 'auto' below?

Take care:
3000MHz = DDR4-6000!

You need to set 1800 for DDR4-3600

3000 MHz = 6000 MT/s.

ok I didn't know that

From another forum, explains it.

"DDR means double data rate. So the effective rate (which is what's advertised) is twice the actual memory clock. So memory clock of 1800 MHz = transfer rate of 3600 MHz. Some applications show one, some show the other."

I don't see anywhere where I can set my DDR voltages from stock 1.2v to 1.35v in this board? I see "VDDP voltage control" but the number 700 or range doesn't make much sense to me. Also the summary says its derived from VDDIO_Mem yet this doesn't seem to be anywhere?

sorry for the noob questions

the ASRock X470D4U is a server motherboard with ECC support, not made for gaming.

That's like saying you can't race with a station wagon. It's not specifically designed to game but there's no reason you can't game on a ASRack board.

that is exaclty what i have sayd. thanks for repeating.
not made != you can't

You are partially correct, this board supports unbuffered DIMMS and does not require ECC.

The primary issue is that the board does not by default go above the JTAG memory specifications. Their specs sheet say it supports 3200Mhz but without any changes my ram is running at 2600hz

Yep.

I'm still trying to figure this out... I found this german forum and someone shared a recording on what the settings may be and a calculator to do this manually...

Need to figure out if this will work and if I can at least make the 3200hz advertised 'supported' speeds although I am hoping for the 3600hz

I own a similar board - X570D4I-2T - and got a great deal on 4x 32GB non-ECC SODIMMs (vs. paying twice as much for slower ECC):



As to the relevance of my post, (1) my memory - rated for 3200 MHz - defaults to 2400 MHz without pulling any levers in the BIOS; (2) I got 200 MHz above that rating simply by changing the speed to 1700 MHz (x2 = 3400 MHz); and (3) sett Infinity Clock to 1700 MHz as well (reduces latency or something [shrug] ).

Server boards and SODIMMs = heresy nearly approaching gaming on server boards. Enjoying a slight spin on @Wasmachineman_NL 's astute observation suggests there is no reason why a server board can't be designed with 260 pin "laptop" memory. Enjoy your OC endeavors.

By default the VDIMM is 1.20V (DDR4 JEDEC standard). On the board's manual there's a setting for MEM VDDIO (page 56/57) that should control VDIMM.
But I just checked on the UEFI setup and I didn't see that option on my machine. I am not sure if it's because I am on an older UEFI version (P3.30) or because my CPU is not officially supported (1st gen Ryzen 7 1700).
