New gaming PC, £1000 budget, need help

You are likely not using the proper settings. Keep trouble shooting with the MSI rep on that site. I don't use the automatic feature, but instead fine tuning it myself. Pretty sure the RAM isn't the issue here.

It overclocks manually fine, set the multiplier to 42x to give me 4.2 Ghz, is running at 32C on full load...

So it's running like a dream

Thanks for your help

Very nice. That H100 is just an awesome cooler. I bet you can take that to at least 4.8GHz.
