DDR Training ??

[ggilmour53]

With your input I am quite happy with the results.
This will keep me going until DDR5 starts to arrive, do you have any insight as to what the first batches of DDR5 will bring??

See here, https://www.techpowerup.com/review/future-hardware-releases/#ddr5
But i wouldn't want to be a first adopter. I always give it plenty time to mature first.

I check MSI support to see if there is new BIOS daily but I am not getting no available download at the address ?? , https://us.msi.com/Motherboard/support/MEG-Z490-UNIFY

You mean you don't see the list of BIOS versions? Maybe their servers are acting up again. Although it works for me at the moment.

I think I have have had the MSI-Unify-Support link work 2 times out of at least 10 try's , no idea why that is

I noticed on boot after a long gap ( me sleeping ) that the RTLs or IOLs were out of sync a little but after a restart they were OK, so I thought I would try lowering tRFC to 620 with this in mind so it did work , exampes follow first img the cold boot second img the restart Is this normal behavior ??

Is "Memory Fast Boot" disabled or enabled or Auto? Auto should be enabled. I like to set it to disabled, then the RAM trains on every boot. This way, at least for the RTLs/IOLs, it can determine the best value each boot. When you notice that they're wonky sometimes (e.g. 74/70 + 15/9), maybe some other setting is also a bit too tight for comfort. It doesn't always have to be tRFC. But if it is tRFC, you can set it another 10 higher, doesn't make a big difference.

I have Fast Boot set disabled, is that ok or should I set it to auto??

 

[citay]

Disabled is ok. I use that too. Auto/Enabled boots faster, but with manually optimized RAM timings, it's more important that it always passes training reliably. Since it trains on every boot, you would notice immediately if there's a failure, because it would show the "Overclock has failed, press F1/F2" error message during POST. Which could happen on a very hot day, with timings that would juuuust about work on a cooler day, for example.

At this point, my RAM is so stable that i could probably set it back to Auto and enjoy a couple seconds less training time each boot. Once your RAM always trains rock stable, you can set it back to Auto.

I shall keep that in mind we are have just left winter here so warm weather is coming.

I was wondering why we are getting DDR5 ram for next gen motherboards when I have DDR6 on my GPU which is running at a stock 14000mhz. Is it the price?

 

[citay]

On the graphics card it isn't DDR6, it's GDDR6. The development is not parallel with DDR, meaning, GDDR6 is still somewhat comparable to DDR4, and is not two steps ahead. As for the frequencies: Since GDDR is soldered onto the PCB, and is right next to the GPU, it's much easier to optimize for high freqencies than normal RAM modules that have to be plugged into sockets.

That's the equiv. of DDR4-3500

Wow I learn something new every day haha, thanks guys
