memory XMP profile causing instability?

Post by autobotguy » Tue Sep 24, 2019 7:01 pm

I'm building a new Ryzen 3700x system with an Asus ROG STRIX B450-F motherboard and the T-Force 2x8GB 3200Mhz(TLZGD416G3200HC16CDC01) memory kit. I can't for the life of me get this memory to run stable at its rated XMP profile. I set it properly in the D.O.C.P in the AI Overclocking Tuner with the 3200Mhz profile and windows 10 pro bugs out and reboots. If it de-select the profile the system boots normally and operates just fine. Do I need to slightly up the memory voltage? Sorry...upgrading from a Sandy Bridge i2500k system and there are new things to learn. Any information would be greatly appreciated. System is as follows:
AMD Ryzen 3700x
Asus ROG STRIX B450-F
TeamGroup T-Force 2x8GB 3200Mhz DDR4
Adata XPG SX8200 Pro 512GB M.2 NVMe
XFX RX 5700 XT

A number of things:

Is that memory on the QVL? If not then I wouldn't count on it reaching 3200. It might get there, but it's an unknown. You might be able to compromise and reach 2800 which is above default but below your module rating.
Do you have the latest BIOS for your board?
Download HCI's memtest. Even if you have a setting that will boot into Windows I still recommend running memtest to make sure you don't get errors.

As for voltage...maybe. That's probably the easiest thing to do but I haven't had much luck with it on Ryzen. I believe my issues are overall compatibility and the memory controller on the chip. I haven't been patient enough to tinker with all of the sub-timings nor brave enough to push more voltage into the chip. I've got 95% of the rated speed so that's close enough for me.

I've had mobo/memory combos that did not play well with the XMP loaded settings but worked fine if you manually set the exact same settings as the XMP profile. Give it a shot at least, see if you get lucky.

I have found that memory in general is so freeken finicky.
Glad your issue is resolved :)

For the future -

Memory timing and frequencies depends on a ton of factors, two of which are the actual design of the CPU and the motherboard. Intel has a XMP certification program that can help make sure that your CPU, with the right motherboard, will work at the speeds printed on the DIMMs. And this will definitely vary based on CPU, modules that were tested on a z390 platform may not perform the same on an x299 platform due to those subtle differences.

Of course this doesn't help with your platform unless someone else has done similar certification.
