Is r5 5600x enough for 3x RTX 3060

[Hudzell]

I don't know the "lane" thing actually, so if I am not wrong. My cpu don't have enough lane for 3 cards.

What happen if i try to run this system with not enough lane ?

 

yea i want to do mining.

Refer to your motherboard's manual to know the lane division for PCI-e devices.

The 5600x has 20 PCI-e Gen 4 lanes. It will likely run them at 8x/8x/4x or 8x/4x/4x or possibly 4x/4x/4x. Which is still enough since it would be 4x PCI-e gen 4, which provides the same bandwidth as 8x PCI-e gen 3, which is plenty of a 3060. (Unless you have a B450 motherboard that's still PCI-e Gen 3)

 

That said. I'm guessing this is not for gaming, right? Since Nvidia essentially killed SLI a while ago.

So if this is for some other purpose than gaming, it will probably be fine. Else for gaming there's no point and is a waste of money. (mining? Nvidia nerfed that too)

I'll do mining also using gigabyte b550 aorus elite. so at reddit i saw a comment and it says 3060 needs minimum PCIe 3.0 x16 i don't know if this right or not.

 

Long story short, running these cards at 4x/4x/4x will affect my hashrate ?

A 3060 will likely not saturate 16 lanes of PCI-e 3.0

4x lanes of PCI-e 4.0 is the equivalent of 8x PCI-e 3.0. Which is enough for a "lower end" GPU.

 

 

That said. Your motherboard... is not even 4x for your other slots. Sorry.

 

-You have a single 16x gen 4. That's good.

-Your other two "16x slots", are not actually 16x. They don't have the pins to be 16x (If you look into them, you will likely be able to see this).

-They are 2x and 1x Gen 3. Not Gen 4. Meaning they are certainly NOT enough to handle a 3060 for anything, let alone mining.

1x is Barely enough for for a regular SATA SSD, with a max theoretical speed on 1x gen3 of 985MB/s. 2x is double that.

then which motherboard should i use ? can you suggest a motherboard ? it better be cheap like gigabyte

also, as i said is my r5 5600x is enough for 3 cards ?

Well it can't be a cheap b550 motherboard. A b550 only gets 10 PCI-e gen 3 lanes to share with the sata ports.

You will likely need a X570 motherboard.

A quick search led me to this one

https://www.gigabyte.com/Motherboard/X570-AORUS-PRO-rev-10/support#support-manual

Which has a 16x, 8x and 4x lanes in its 16x slots. The 16 and 8 runs directly off the CPU while the 4x runs off the chipset. They operate at Gen 4 speed with a 3rd gen Ryzen (what you have).

Though it might be more expensive than you'd like, so if you want to look for one yourself that's cheaper, go ahead.

The 5600x has 20 lanes by itself, it should be ok for your purpose as long as the motherboard shares the lanes properly to where you want them to be.

Thank you but my english not that good so 

if im not wrong, i can run 3 cards smootly w/ r5 5600x with the x570 at gen 4 speed right ?

It likely will, yes.
Depends on the motherboard. Some may dedicate more lanes toward having more M.2 slots, while others push toward more PCI-e lanes for graphic cards.

So how I know a motherboard push toward more to PCI-e lanes or not at buying it ?

You check the tech specs. You look at the one that says 3rd gen Ryzen and the chipset.

The board I linked previously has two x16 slots, wired for x16 and x8 linked to the CPU and another x16 slot that's linked to the chipset and is 4x.

It can be confusing for sure. But should be easy enough when you know what to look for.

Most of the mining algorithms don't care about PCI-E bandwidth (or in other words amount of lines). 

So most of the miners are using PCI-E riser like this https://www.ebay.com/itm/284265350815?mkevt=1&siteid=1&mkcid=2&mkrid=21572-161791-658771-9&source_name=google&mktype=pla_ssc&campaignid=12963178471&groupid=120426658263&targeted=pla-1248581038030&MT_ID=&adpos=&device=c&googleloc=9062894&itemid=284265350815&merchantid=116792603&geo_id=56&gclid=Cj0KCQjwpf2IBhDkARIsAGVo0D2U8DUS4a6RXyAWA7Vug9XSJrP2cuPvxGVegSe2_x3tKQ7nwAiP5w4aAj1xEALw_wcB so their card have only one PCI-E line and it works just fine. 

 

This apply to mining only, if you want do something else with this multi GPU design (Folding or Rendering etc) you will need more lines per card but for mining it's not necessary.
