7900 XTX clock speed

I just did my new build and got the XFX Speedster 310 merc version of the 7900 XTX. I notice on their website it says 2615 MHz is the boost clock. But when I’m playing a game I see it go up to as much as 2935 MHz. When I check MSI afterburner it shows 2935 as the “core clock”. Is this normal or problematic?
