Maximus Z690 and Alder Lake: Modern CPU’s require Modern Overclocking Solutions

[Hopper64]

Saw you have a Maximus Extreme in an earlier post. I don’t see that particular kit on the QVL at this point. Could be validated later by Asus or Corsair. Corsair may have already validated it. Not sure.

That’s the problem. You have combined memory kits. Use one or the other, not both. Â*

I need 64GB of RAM

[Hopper64]

You can’t combine 2 kits to achieve that and expect stability. That may be the whole issue for you. Test with one kit first.

With two sticks is obviously mode stable but it's a shame, ddr5 is a crap at this state.
DDR4 is way better, faster and cheaper.

I have 1k euro of DDR5 and I can't go past 4.4GHz.
Ddr5 at 4.4GHz is slower than DDR4 3600 and it costs two times more.

This is a shame.

The difference is negligible. Depends on resolution and what you’re doing.

I don't know if you read that article I spent two times more to go slower than DDR4 that costs half the price.

They say:
That's also why I included the DDR4-3600 CL16 "sweet spot" configuration in the test results.

I can't even go 4.8GHz with 4 sticks.
Same problem if I choose to go with 2x32GB kits.
i need to use 4.4GHz.

Ddr5 currently permits higher frequency only with 32GB total. This is a shame.

This is false advertisement, DDR5 is a fraud.

Hello,


Best to do some research before pioneering and investing in new technologies.

If not well versed in the pitfalls of combining memory kits, it's best not to. See the article here: https://rog.asus.com/forum/showthrea...atoes-overview


Memory is binned in the density in which it is sold, if you combine kits - you eat into the guardband which is put in place by the memory vendor to ensure the best possible chance of XMP compatibility. There are, however, no guarantees.

Use one kit, and tune accordingly.

This is not a problem of combining memory kits. This is a ddr5 that isn't able to reach the jdec frequency when using 64GB total.
32GB kits is dual rank and it's the same crap of my 4x16GB kit.

See chart below for stock frequency operation based on config.

This is why you must have 4GHz for 64GB.
There is no 32GB single rank stick

This means that with 64GB of memory, you are stuck at 4GHz base frequency and this means that you go slower than cheap DDR4.

This is a shame.
