Did you manage to figure this out? The same crazy flickering started on my system too (I have the crucial ballistix 3600 cl16 RGB) and MSI B550 Meg unify motherboard). It all used to work well before, not sure when it started as my system is under the desk and only noticed a few days ago. Mystic light does not change or control the rgb on the ram anymore (it identifies the ram rgb, but when you change any settings this does not happen on the ram lighting, not even turning the lighting off works) MOD software does not control the lighting at all, I've updated windows 10 latest updates, installed all the latest msi mboard & Asus RTX 3070 GPU drivers.

I get almost identical speeds to that you have in crystaldiskmark on my 2tb SN750! My Read speeds are around the 3130 MB/s, and my Write's are also around the 1140MB/s. Have you managed to work out how to get th write speed any higher? or is this normal (other people are reporting write speeds above 2000MB/s, and in all the reviews too. I have tried turning write caching on & off, and also write cache-buffer flushing on & off with very little improvements, I have also tried booting in safe mode (in case some software/antivirus/drivers are the cause) and got the same around 3100 MB/s read and 1100MB/s Write speeds. in WD dashboard it shows 4x lanes. It is not my OS drive, the drive is brand new, with nothing on it. I have a brand new MSI B550 MEG unify motherboard, with an and 5800x cpu, my main drive with windows10 is a samsung 980 pro 1TB and I am getting just over 6100MB/s Read and 5500MB/s Write with the Samsung in the 1st m.2 slot. My second drive the WD tops out at 1100MB/s write and I cannot work out why.

ok, that makes sense in a way. Thank you

How would someone know/work out when you would need to populate all the power connections on the B550 unify? I've been scanning the web to get a better understanding of this board and what it can do (call it curiosity & enjoying tinkering with tech) - I know it works without plugging in PCIE_PWR1 (I am using it), but when would I need to use the extra connections? I've not been able find find an answer on when would you need to plug in PCIE_PWR1 - everyone seems to say you don't need to plug it in, but not when you would need to plug it - why is it there? When would it need to be plugged in? I was hoping there were some info along the lines of: if you do [x] then you need to plug in CPU_PWR1, if you do [Y] then you need CPU_PWR1 & CPU_PWR2, and if you do [z] then you need to plug in CPU_PWR1 & CPU_PWR2 & PCIE_PWR1 Do you know how if can find out more? Thanks

Thank you for replying, I currently have a Ryzen 7 5800x, but plan to upgrade to the 5900x as soon as they become more available and the silly prices drop. The reason this board looked great to me was that it has four m.2 drive slots, and I intend to fill these up over time as I find them on a great deal. Currently I have a 1TB 980 Pro installed (and have a second 512MB one i will move from my other pc) Do you think that with a Ryzen 9 5900x CPU, 4 nvme drives, and RTX3070 - that I don't need the second 8 pin CPU_PWR2 & the PCIE_PWR1 to be connected and connect two separate PCIe cables into the RTX3070, and it should be ok with the hx750 psu? (I've tried to check the msi website & Manual, but but there is very little info to guide you on when to use CPU_PWR2 & PCIE_PWR1 it just says plug it in) Thanks for the help

I got convinced on this forum to go for a B550 motherboard over x570, and got the recommended MSI MEG B550 Unify (instead of the Tomahawk X570) - saving a cool £10 for the "cheaper" B550 motherboard. As I installed the Meg B550 Unify motherboard I realised that my Corsair HX750 psu doesn't have enough PCI-E power connectors for this board! The HX750 only has 4 x PCI-E (6+2, 4+4 CPU) connectors, alongside 6 x Peripheral/SATA connectors, and the 24 pin ATX connector. The MEG B550 Unify motherboard has the 24 ATX connector (ATX_PWR1), 2 x 8 pin PCI-E connectors (CPU_PWR1 & CPU_PWR2), 1 x 6 pin PCI-E connector PCIE_PWR1 My Asus RTX3070 needs 2 x 8 pin PCI-E connectors, which means I am I x 8 pin PCI-E connector short on my HX750 PSU..... By calculations I only need about 500 - 550 watts, which I thought my hx750 was plenty, but now I don't have enough power connectors on my PSU for the B550 MEG - ironically the 850 watt psu's has 5 x PCI-E/CPU connectors. (Now the B550 is cheaper does not sound like such a valid argument anymore, as I have to spend another couple of hundred £'s for a 850 watt PSU which has 5 x 8 pin PCI-E connectors) What do I do now, return the B550 motherboard, and order the x570 tomahawk (as it needs only 2 x 8 pin power connectors), or spend another whack of money on a new psu (when my hx750 was not cheap and is only about 12 months old). Does anyone have any ideas or workarounds? In the mean time I have connected my RTX3070's 2 x 8 pin power connectors on the same cable (which is not recommended)

Need help to choose motherboard for Ryzen 7 5800x
XTPCGuy replied to XTPCGuy's topic in CPUs, Motherboards, and Memory
Thanks, I was thinking the same. It always worth seeing what people are experiencing. -
I just received my second Ryzen 7 5800x CPU - (got on sale), and am stuck on which motherboard to go for. The first one I built for my son 3 months ago, and went for the MSI tomahawk x570 WIFI motherboard - and I can say its a brilliant board, performs well, runs cool, no noise from the onboard fan, my son games a lot, the CPU temp is between 34 & 36 on idle, and 60 - 75 under heavy load (this is in contrast to a lot of people saying the 5800x runs hot, not in my case here). And here lies my blocker- do i just buy another MSI tomahawk x570 wifi - as the one my son has is great, and the ryzen 7 5800x runs cool on it, or do I try another motherboard? The list of motherboard I've narrowed down to (and cannot decide on which one to go for ) : MSI MAG X570 Tomahawk Wifi - cost £209 Asus ROG STRIX B550-E GAMING - cost £200 MSI AMD B550 MEG Unify - Cost £200 ASUS TUF Gaming X570-Plus (Wi-Fi) - Cost £200 ROG STRIX B550-F GAMING - Cost £200 MSI MAG B550M MORTAR WIFI - Cost £170 Gigabyte B550 AORUS ELITE AX V2 - Cost £160 What do you recommend, what's your experience with these boards and the Ryzen 7 5800x (who people says runs hot, but not on my son's Tomahawkx570)?
-
You make some compelling points, I will have to think a bit more on what I want to do, I first thought to put a smaller nvme 4.0 drive, and later a bigger second one when the price drops, and I know there are other options, ( it still feels weird paying more for a B550 than a X570) , but you do make some good points. Thank you
-
I hear what your saying, and thanks for all the info. I've had a quick look for prices and availability, and most of the boards you recommend are more expensive than the Tomahawk X570, and also quite a few are not available currently - Apart from the Gigabyte B550 Aorus Elite AX V2 which is the only one cheaper in the UK, from what I can see the Tomahawk is stronger in terms of VRM , its very close to Flagship motherboard VRM performance (from the review on the itech blog - google "MSI X570 Tomahawk Motherboard Review by itech")
-
I thought the x570 Tomahawk wifi is one of the newer versions (released in may 2020) and is priced at quite well at £200. Which mboard would you then buy/recommend instead?
-
Ok so it looks like I'm leaning towards the MSI MAG X570 Tomahawk Wi-Fi - whilst being slightly nervous as I've only had Gigabyte and Asus motherboards in the past and they've never failed me. Before I press the buy button, I'm wondering: Is there any reason why not to go for the MSI MAG X570 Tomahawk Wifi?
-
I've had a quick scan, so its basically between £20 & £25 saving if I go for one of these B550's instead of the X570 Tomahawk. Thanks for the advice.
-
would you recommend these B550 over the MSI MAG X570 Tomahawk with Wifi priced at - £206 ?
-
Thanks for the advice (on board and case)
