2700X build questions

[Brad Robbins]

Upgrading my old home PC which was an FX series 6 core and a 1070 with a stack of SSD and storage drives.

New gear is as follows:
AsRock x370 killer SLI/ac mobo
AMD 2700X CPU with stock prism cooler
G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600)
Additional 1070 for SLI (used from a coworker cheap YAY!)


So far I have a few issues. My build so far is RAM, MOBO, CPU, and one SSD only. Using an older nvidia 210 gpu for testing then once all is stable will replace with the 1070s.

The BIOS set the RAM to 2133. At this speed and at 3200 (from XMP profile) system stability was crap. Constant various BSODs. It was better at 2133 though. I have updated to the newest BIOS and updated all drivers from Asrock. I have not tested much, but stability at 2133 seems better, but still crashes frequently at 3200. Is it possible to get this stable at 3200? I have read some threads where it is not, but my work PC (built earlier this year) uses a 1700 and DDR4 3000 - and runs fine at 3000.

Also, I used stock thermal paste that was on the cooler. Idle CPU temps (stock clock) are 50c peaking to 61c (measured in hwinfo not BIOS). This seems very high. Should I clean and repaste or are these normal temps for a 2700x?

From your motherboard specs * AMD Ryzen series CPUs (Pinnacle Ridge) support DDR4 2933+(OC)/ 2667/ 2400/ 2133 ECC & non-ECC, un-buffered memory*
Try running the RAM at 2933MHz that will still be overclocked on that chipset but might be stable. The x370 doesn't support RAM with the same speeds as the x470, one of the reason why it is best to use the 400 series of chips when building a Ryzen 2XXX system.

I got the mobo on a deep sale. I will probably upgrade it inside of a year, when I have the budget to switch to an NVME drive too. Right now I have stepped down to 3000 and it seems stable.

What about the temps? Any anecdotes from anyone about normal CPU temps for a 2700x?

Yep, the older motherboards don't usually support speeds over DDR4 3000, and if they do they're quite fussy about which RAM is actually used.

Check the cooler locking tab is fully down, it feels quite fragile and some builders are a little scared to push it fully home-it should be parallel with the MB surface when fully locked.

[strike]Your temps are perfectly safe so no worries there[/strike]. As for the memory I agree you may need to drop it down to 2933 but your going to also want to manually adjust the voltage. You could try DOCP however every time I've tried it on my new build it keeps failing (off this weekend so I'm going to work on it).

The temps sound OK. When you say peaking at 61C is that under load or is that an idle temp fluctuation?

It is well locked. It was a little tough getting it on, but I have built PCs for 20 years, so I managed

I left the PC idle. I was not monitoring CPU, so some OS process could have spiked for a bit, but in a 10 minute idle run 61 was the max.

Ok I misread that, 61C is quite hot for idle, even with the stock cooler. Are you sure the cooler is installed correctly? If so run a game or CPU instensive program and monitor the temps with HWmonitor & Ryzen Master. Do this for like 15-30 mins and let us know what temps your getting.

I think it is okay. I am monitoring with HWinfo and running Hot CPU Tester. Max Tctl is 66.3c. I think my average idle is going to be 48-51c and the 61c I saw was from some background process (my bet is on windows update).

Also it has been stable with RAM clocks at 2933. 3000 was still a touch unstable. I do have a 1700 on a gigabyte x370 board running at 3000 fine, but I guess this combo does not like it. For the uses of this machine it is fine for now.

Ok so yea your max temp is fine.

 

[Brad Robbins]

Temps are fine, but I am still getting app crasshes and BSODs - even at 2133. I have slower DDr4 RAM here at the office I will test, but I may just return the mobo for an x470.

Also have some SLI kinks to work out, but that will come after system stability.

Thanks for all the help.
