***The Official 5900X \5950X owners thread***

This might be the best place to ask for a mobo recommendation for the 5900X? Just looking for a rock solid B550 or X570 motherboard, with reliable NIC, decent VRM cooling etc.

if you want rock solid avoid gigabyte ^_^

Oh? Do they have a reputation?

I use an MSI X570 Tomahawk which would seem to fit your requirements, but I don’t know how it compares to other x570 boards in terms of price and features. The tomahawk could be considered expensive and crap now for all I know!

I've had the Tomahawk recommended to me elsewhere, so that's a good sign! Is the B550 version held in high regard?

 

[Dirk Diggler]

I've been using my Tomahawk for a couple of years now with no issues.

Asus strix here. X570-f been great so far and stable with 4 sticks of memory.

 

[uscool]

MSI x570 unify been fine for me , the tomahawk punches well above it's price point

went with a B550 Unify. beefy vrm, 6 sata connections (I have loads of SSDs) and a bios reset button (used this several times with overclocking my memory already). If the tomahawk had a bios reset button I would have gone for that.

 

[von Humboldt]

Thanks all. Looks like there are plenty of good options.

Is the B550 version held in high regard?

It is by me, magnificent board. If I could critique it on anything, it's the lack of standard USB ports, think it only has 6, but it does have internal headers so I have another 4 on top of the case. Push came to shove, I'd just get a powered USB hub if I ran out of options. Also the second M2 slot is PCI-E 3.0. But given there's not a noticeable difference in performance between NVME PCI-E 3.0 and PCI-E 4.0, and even SATA, unless doing lots of read and writes between SSDs, for normal use like browsing, viewing videos, gaming, the fact that the M2 is PCI-E 3.0 is hardly an issue for someone like me.

The X570 will no doubt be the same, but this board is thick and its build quality is awesome. So you can't go wrong with either X570 or B550 Tomahawk boards, would depend on your use case which one you'd take.

Great feedback, thank you!

Did you change the process priority in Cinebench before starting the run? For some reason it's always set to below normal, try setting it to normal or higher and see if your score went up, this doesn't make too much difference on a fresh install so there's not a lot of background process running, but on a standard installation, it helps.

do you have a 5950x?

 

[MrFrazzles]

if anyone here has a 5950x please tell me what your chip goes to in terms of mhz PBO OFF while running cinebench R23, as mine seems to be capped at 3.75ghz, while i've seen many have 3.95ghz at stock.

What is going on here.

R20 scores an embarrassing 9300, which should be around 9.7-10.1k stock

 

[heatonpkmassive]

it's 100% not cooling. i have 13 fans inside my case with a 360mm aio in push/pull config. Like someone said earlier, it's probably a crappy ASUS bios setting i need to tweak.

Are your fans set up so that front/bottom are intaking and rear/top are exhausting?

You could be hitting a limit caused by your motherboard and / or bios. Open up hwinfo64 and have a look at PPT/TDC/EDC percentages - do they hit 100% under load? Have a look at core voltages - does the max value go above 1.4 volts per core?

3.90-4.0 is normal for stock settings.

Things you can try are to make sure you are on latest motherboard bios, oad optimal defaults and enable xmp ram settings. Install latest amd chipset drivers to make sure power profiles are in check.

Also in bios for my asus board I set fmax enhancement to off (I don't know what the auto setting is doing) as well as setting Performance Bias to off to stop AI sense deciding what's best for specific software.

Temps should be a non-issue on these cold days

so me getting the 3.75 ghz isn't normal?

yep exactly like that

Yeah honestly so strange. I get around 24k multiscore in R23 and around 1600 singlecore, that's at stock of course.

However R20 just doesn't treat me well. 9300 for the most part multiscore, but around 620 for the single

Something is definitely off - my board is the x570-e gaming wi-fi ii. On the current bios version, all stock bios settings apart from DOCP which i have enabled to give me 3600mhz on the 64gb of dominator (4 modules)

Could it even be a teething issue with R20? Maybe an incompatible windows version or something? I just want to eliminate that fact it could be hardware related, even though i really don't think it is given the performance of this cpu in R23 being seemingly normal.

Any ideas at all?
