re: PC Discussion - Gaming, Performance and Enthusiasts

It's real. You can get tras crazy low now on DDR5.

I don't see trying to squeeze more out of my cpu or ram until my GPU gets better, but holy shite, that's nuts.

I did all of them. The guide was for all like 50 settings for that shite took awhile.

What did it say about setting tRAS?

Ever since you first posted your primary timings, that tRAS timing struck me as odd, and especially because I don’t remember spending much time on it when I was OCing/tuning my RAM. I kept thinking “I want to say that was just a straight formula…” but it had been so long that I couldn’t recall. Just looked it up, and now I understand why. Having a tRAS lower than CL + tRCD basically gets ignored for a simple reason: CL and tRCD must complete before the tRAS time as tRAS is the amount of time a row needs to be active to have data read from it. CL is the delay from request to ready to read and tRCD is read time. The row can’t be active for less time than those combined. So regardless of what your motherboard is allowing for input for tRAS, with CL at 30 and tRCD at 36, your tRAS is running at or above 66.

Eta: The above is at least to my understanding. RAM is half voodoo to me. If anyone knows better, feel free to correct me.

No, tRC is another formulaic one, though. It’s tRP + tRAS. Just so happened that because your CL and tRAS are both set to 30 that the ultimate equation would come out to 68.

I wouldn’t spend more than like $300 for a mobo… just find an MSI or Gigabyte X670 board that has as many m.2 slots and fan headers you need.

Honestly, he could probably get away with a B650 board, as long as it has the features he needs. x3D chips can’t (really) be overclocked and aren’t particularly RAM sensitive, so beefy VRM isn’t really necessary. And contrary to what the marketing might say, we aren’t going to need PCIe Gen 5 x16 for another decade. We are barely saturating Gen 3 x16 at this point.

My friend went with that exact mobo for his build and has had no issues. And yea you don't "need" to go x670.... you could save money and go the B650 route... but if you are already going for a 4090 build... what's another $50 for some extra features you may want or use.

But... make sure you are a case chad and build in a Phanteks NV7 or NV5... cleanest cases on the market

Thats the one in my Newegg cart. I like the Tomahawk boards.

performance and features aside - it's just a good looking board

I don't want dragon logos and colors and goofy gamer shite in my computer

never even heard of these. ill check them out

was planning on a fractal meshify 2
