[SOLVED] 3900x on a b350 board

Furzumz

Reputable
In a earlier thread someone told me a b350 isn't ideal but would be fine with some air flow from a CPU cooler. I forgot to ask them for more information so I'm wondering, whats the danger involved?

Mobo overheating or something?

I'm currently using an AIO - should I swap it out for a air cooler asap?

The motherboard I'm using is a B350M PRO-VDH by msi. Not doing any manual overclocking, the only overclocking is that boost thing thats enabled by default
 
Solution
If you're not actually pushing the 3900X, then it should be fine in that board. Turn it around: you wasted money if you didn't really need it.
But I'm going in circles... so, moving on.

yucky power supply (Apex Gaming 750M or AG-750M for short)
Depends on the gpu more so than the cpu. Gaming graphics cards are the most stressful component for psus to deal with, and the part most likely to cause trouble when users pair them with lower quality units.
From the reviews I came across for the 650, 750, and 850w models, it's certainly not spectacular, but it's not going to blow up your PC either.

need a better cooler (currently using a corsair h55)
Are you currently experiencing high thermals with the cpu now - over 85C? If...
It looks to be compatible but personally I wouldn't put a $400 CPU in a $80 motherboard. The VRM section looks a bit sketchy.

If I knew about this stuff ahead of time I would of went with something different :sweatsmile:

So far its been fine but am I any danger of destroying anything? I made quite a few mistakes when putting my current build together, trying to figure out what I need to replace and within what priority
 
The risk is VRM overheat under heavy loads. Once that's exhausted, you'll need a new motherboard anyway.
One of the cons of liquid coolers is the lack of air flow normally provided over the VRMs by air coolers.
But if you're not actually making use of the 3900X's extra threads, a better question might be, "Why did you even get one?", or "Why didn't you settle for a 3700X?"

Thanks for the info

Lack of thinking things through and lack of computer knowledge

Many mistakes were made with this build when I put it together but so far everyone here has been helping me piece together what I did wrong so I can try to fix it (as always I appreciate all the help guys, thank you)

Here's my list of screws ups so far I'm going to try to fix, I just dunno where this motherboard thing falls on the priority scale
  • yucky power supply (Apex Gaming 750M or AG-750M for short)
  • need a better cooler (currently using a corsair h55)
  • someone said I should replace my ram with something faster ( current ram is 2666 mhz 16GB)
  • new motherboard needed it seems

Are you currently experiencing high thermals with the cpu now - over 85C? If not, I'd say let it be for now, or lower it's priority on your list.

Ehh, depends on what all you use it for.
A)Games
Depends on the performance tier of the gpu. The stronger it is, the greater the benefit of faster memory.

B)Productivity apps
I couldn't tell ya, as I'm not well versed there, but it seems to vary widely depending on the application.



From your checklist, none of those are very high priorities, IMO, it just depends on some things, which I've already addressed.

Just using it for gaming. I should of def. went with a 3700x but hindsights 20 20 as they say

I got this card in particular a 2070 super

Good to hear about the not blowing up my computer part haha. I was worried about that the most when someone said the power supply isn't the best

Most demanding game I got (EA's Battlefront 2) puts it at 81c tops for the highest reading after playing for a few hours, everything else is usually sub 75 such as Vermintide 2 or Planetside 2

Prime95 "blend" test works it around ~85c given enough time. Cinebench will get it up to 95c after 4 or 5 back to back runs

Just games essentially. Everything else is just youtube and web browsing, no video editing or anything demanding like that

I can live with some not top of the line performance at the end of day, my main concern is something getting fried
 
Its also the VRMs will be running at their maximum capacity, which that will fine, but now the question is, how shorten the lifespan of the components it will make by running that CPU.
Under common workloads and things like games, only a portion of the cores will typically be active though, so the VRMs won't likely be getting pushed to their limits, and power draw shouldn't be much more than it would be with a lower-core-count processor like a 3700X. It's only likely to push the VRMs to their limits when doing something that fully utilizes all 12 cores and 24 threads of that processor, which at this time would generally be things like video encoders, rendering software and the like. When that happens, the VRMs might get rather hot and probably throttle performance somewhat, but it doesn't sound like they intend on doing much of that anyway.

someone said I should replace my ram with something faster ( current ram is 2666 mhz 16GB
For gaming, that might be a reasonable option, particularly if you happen to be running that 2070 SUPER at a lower resolution like 1080p, as a powerful graphics card like that will often tend to be waiting for other components like the CPU and RAM to complete their work much of the time. At higher resolutions it will probably make somewhat less of a difference though.

One could also try manually overclocking the RAM, though that might require a lot of trial and error to determine what settings are stable without crashing the system or causing other errors.

Ok, yeah, not the greatest combo of gpu + psu, and the Ventus cooler sucks - product segmentation, yo.

Keep those numbers in mind, because that's what will happen if you actually get around to putting an actual heavy load on this cpu... or whenever your Corsair H55 kicks the bucket... after which you'll need a backup cooler handy.

Is it dangerous to run a 3900x and a 2070 super with this power supply? I'm gonna replace it when I can of course but I dunno what the risks are for the time being
