RAM Support on Mobo vs CPU

[SH0607]

I'm Building a system for the first time, and looking into both AMD and Intel based rigs.

The Intel side of things seems slightly more complex. I want to dabble in overclocking so a Z490 and a K CPU are necessary for 10th gen.

The 10600K/KF is an obvious choice (Gamers Nexus made that pretty clear with their OC benchmarks).

My problem is the following: Advertised support for i5 is 2666MHz, but I'm aware that it's mostly possible to get away with higher speeds.

But on this Gigabyte mobo (https://www.gigabyte.com/Motherboard/Z490-UD-rev-10/sp#sp), at my budget's limit, Memory support at speeds greater than 2666 is listed only for i7s\i9s.

Will I be able to run 3200 Mhz memory with an i5, if it's supported by the mobo, but not for that CPU?
(going back to Gamers Nexus, They used this mobo: https://www.asus.com/Motherboards/ROG-MAXIMUS-XII-EXTREME/specifications/ , with a 4000MHz kit and a 10600k, and it doesn't list different support for different chips)

 

-if anyone is interested: 

 for the AMD option, I'll be going for a 3600/3600x and whatever b550 is well reviewed at the time of purchase, with a 3600MHz 2x8GB kit.

-for price reference- the Z490 UD costs 220 usd in my country (Israel)- going with a high end Z490 like the Maximus, would literally cost me an arm and a leg.

you can go even more, the memory controller on the i5 is reminicient of 8th gen which does 3600 easily if the memory sticks are capable of that.

 

gigabyte just hasnt tested i5 or i3 memory OC on this board.

B450 supports 4th gen with BIOS update so you dont need the likely expensive B550.

Thanks for the quick reply!
I understand that the i5 isn't limited by itself, but is there no possibility that the mobo simply won't allow higher speeds with an i5 installed?

That is, so long as he is not purchasing any PCI-E hardware that is PCI-e Gen 4 rated.

 

Price to performance, I would pick the 3600 non x variant, its a fantastic chip and price to performance is on point.

no it wont be an i5 specific speed limit. Heck even CPUs with locked multipliers support memory OC on Z chipset boards.

Atm there's nothing Gen 3 x16 can't do good enough for gaming, and I doubt even next gen Nvidia flagship will make 3.0 x16 insufficient

Thanks man, I'll bear that in mind if I go AMD

The reason I want to go with b550 is exactly because of PCIe 4 and future support

That's great to know. Thanks again for the quick reply!

That is true, but he would essentially be building himself a machine that could be good for a few years. While it is unclear how long the AM4 socket will be the standard, it is very possible that PCI-E gen 4 could see more and more development in the near future, and could be beneficial for some future PCI-e related upgrades. Therefore a B550 could essentially give him a marginally better upgrade path, but again with AM4 and probably DDR4 being phased out in the next coming years, the upgrade path is limited.

He's not buying the best of the best CPU in the first place, I doubt he'll use any new flagship GPU anytime soon to.benefit PCIe Gen 4. As you said, by that time new CPUs will be on a new socket anyway

Even on the low end of AMD products, a 5500XT is PCI-e 4.0, and I can see one on newegg for <$200 US. Again, I am agreeing with you in the sense that its really hard as it stands now to saturate a 3.0Gen PCI system on a budget build, but 4.0 will develop enough over the next year or two where getting it now might not be the worst idea ever, thats all I am saying.

PCIe 4 on Navi is just for the sake of having PCIe 4, it does not perform any worse with PCIe 3
