Overclocking CMW32GX4M2E3200C16 with Asus Rog Strick Z490-H Motherboard

[MichaelBaggott]

Hello,

I have 2 kits of Corsair Vengeance RGB CMW32GX4M2E3200C16 for a total of 64Gb RAM

I have tried to set the XMP 1 and 2 profiles on the Asus ROG Strix Z490-H motherboard, but these both resulted in blue screen crashes within minutes of booting to Windows

I updated the motherboard to the most recent BIOS, September 2022, same result.

I tried manually setting the Frequency to 3200, Timings according to the Corsair website, and Voltageto the stock setting, which i think was 1.2v, and then setting according to the Corsair website and XMP, which is 1.35v. Everything else i left on auto. I still got the blue screens.

I guess the only other thing i can do is try to gradually increase all the overclock settings until i can find a stable setting where it won't blue screen.

Can anybody give any advice on this?

Thanks 

Michael

XMP is likely going to give you problems since you are combing two kits and the values are not set for that. It is sometimes possible to combine kits, but it is going to require manual tuning. Primaries plus auto settings for secondary and tertiary is the place to start. However, be aware XMP does not change VCCIO or SA voltage and those are both critical to stability. The motherboard sets this automatically based on capacity, but like anything else it often requires tweaking.
