Not getting close to 3600Mhz Memory speed

[WeeemRCB]

Hi

I recently upgraded my PC by switching from Intel to AMD

New Mobo: X570 ROG Crosshair VIII Hero

CPU: 3900X

 

I reused the memory from my old config which was 4x8GB Corsair Vengeance LPX (CMK32GX4M4B3200C16) @ 3200Mhz

In the Intel build I could only get that memory working stable at 3133Mhz, but in the new build it would run at 3200Mhz

 

Some instability/BSOD issues that transferred to the new build and I put it down to the memory as it's the only component that was left to swap.

 

So, as Ryzen likes faster RAM I decided to go for a dual 3600Mhx kit, but I'm not getting anywhere near those numbers.

2x16Gb Corsair Vengeance LPX "Ryzen Tuned" CMK32GX4M2Z3600C18

 

If I try to select the full 3600MHz the PC hangs with Q-Code 22 and the amber diagnostic LED

If I clock it back to 3466Mhz it sticks on qcode 07

 

The only way it boots up is if I dial it right back to 3200Mhz - which is a waste of £40 as I could have purchased a 3200 kit if that's all these can get.

 

I'm assuming I've done something wrong in the BIOS, so could someone steer me in the right direction so I can get the proper RAM speeds?

 

My settings in BIOS (with mild OC):

Ai Overclock Tuner: Manual

Memory Frequency DDR4-3200MHz

Core Performance Boost: Disabled

CPU Core Ratio: 40.00

CPU Core Voltage: Manual

CPU Core Voltage Override: 1.15v

DRAM Voltage: 1.35v

The rest are fan profile changes

 

If I try to force RAM voltage to 1.35v and push beyond 3200Mhz I get a Q-Code: 22

If I try upping it from the stock 1.20v to 1.25v I get Q-code 07

So it doesn't seem happy with any voltage changes ...

 

Any help appreciated

Aaaaah.

In my old Intel ASUS mobo that was there.

In the new AM4 ASUS board they renamed it "DOCP"

 

A quick google search for my Mobo and XMP returned the following from overclockersclub.com

"...but what might stand out is ASUS has gone with the Direct Over Clock Profile (D.O.C.P) naming for memory profiles instead of eXtreme Memory Profile (X.M.P.). While technically I would say ASUS has it right, the world has adopted the XMP naming scheme and it is the exact same thing"

 

Enabled and boots up fine.

Thank you. I owe you virtual beers
