Corsair Vengeance RAM Crashing at 3600 MHz (XMP1)

[Luvvo]

Hi all,

I have "Corsair Vengeance RGB PRO Black 16GB (2x8GB) 3600 MHz AMD Ryzen Tuned DDR4 Memory Dual Kit". https://www.overclockers.co.uk/cors...zen-tuned-ddr4-memory-dual-kit-my-4c1-cs.html

I was running 2x8GB sticks at the 3600MHz frequency with no problems. For a month or two I didn't realise it defaults to 2622MHz unless you change it in the BIOS.

My drivers are all up to date, and I've even ran a WIN memory diagnostic tool with no problems raised.

Now I've recently upgraded to include the additional sticks to take me to 32GB.

However my PC crashes on launch and tries to auto recover every time, unless I disable XMP1 and go back to 2622MHz.

Anyone know what the issue is?

Many thanks,

I got new 2x 8GB LPX 3600 sticks to make 32GB. Older sticks were Samsung, newer ones were Micron, XMP was stuffed, so disabled and upped voltage to 1.40v, will now run solid on Memtest 3866mhz, or 4000mhz at 1.450v
check yours in Cpu-z

Which Ryzen CPU do you have?

@turbot1984 - Yeah good spot. Seems I have 2 sticks from Nanya Technology, and 2 from SK Hynix.

Anything I need to do other than in BIOS just manually set V to 1.4 and the MHz to 3600? Seems odd that XMP would throw windows into recovery but manually setting the same wont?

@Tetras Interesting you jump to an AMD CPU straight away, but I do have a Ryzen 9 3900X 12.

No thats it. You may be fine on 1.350v @ 3600, do a couple of Win 10 mem diagnostic runs to check.

Thanks again @turbot1984 all working!

I asked because if you're running 4 sticks on Zen or Zen+, you won't achieve 3600. It's not guaranteed on Zen 2 either.

Great stuff!
