Bought some new components - how much did I mess up with memory timings?

Hi.

I like to play Amazon New World and currently run a AMD 2700x with a Geforce 3070. I'm not getting great FPS (Dropping down to about 15 regularly) and so I've decided it's time for a new processor/motherboard/memory.

In a bit of a hurry at the time (there was a today only offer on and I had kids with me), I've bought this:

MSI MAG X670E TOMAHAWK WIFI,
AMD Ryzen™ 7 7800X3D, AM5, Zen 4, 8 Core, 16 Thread, 4.2GHz, 5.0GHz Turbo, 96MB Cache
32GB (2x16GB) Corsair DDR5 Vengeance Black, PC5-48000 (6000), Non-ECC Unbuffered, CAS 40, XMP 3.0, 1.35V 7RFHB

I should have looked into it more, as I just saw "32 GB 6000Mhz" from a good brand and went with it. Only since buying it (and before building it) have I read that the CAS 40 isn't ideal.

My question is: How much is that likely to matter? If this was you, would you return it and put off building it just to get some lower timings, or is it going to make very little difference? The thing I'm kicking myself for is that CAS30 is about the same price and so I had no real reason other than not knowing to go for CAS 40.

Is it worth the faff of wrapping, posting and waiting in for another delivery or will this not make much difference at all because of the cache on the 7800x3D?

If it makes a difference; I'm looking to game at 5k/2k and I don't really care much for FPS over 60 for this game - it's an MMO that doesn't require super high FPS but the 15 I'm getting at the moment is horrible.

Not much, see here.

This video is exactly what I wanted to see. Can see that we are looking at maybe 1-2fps difference, if any. In some places it makes no difference. I'm comfortable with that.

Can you not cancel it or have you already received it ?, lets just say my DDR5 runs at 8000mhz tighter timings than that, but I did go through a few kits to get where I am.

Unfortunately, I've already received it. I can still return it though.


I think I'm going to keep it - that difference in performance really won't be noticed. I'm playing casually rather than competitively and don't get a huge amount of time to play. My main criteria is that it looks good and is playable. It doesn't need to be the absolute best of the best.
