Ryzen 1700 with Asus Rog Strix B350-F - can't get it to 3.6

[scott.tunstall]

Hi,

I wish to overclock my CPU to run at 3.7Ghz.

I have this setup:
Windows 10 April 2018 update
Ryzen 1700 w/ stock cooler & thermal paste
Case is Antec 1100 (oldie but a goodie)
Rog Strix B350-F GAMING board (BIOS is 4011, released 4/19/2018 )
2 x 8Gb sticks G.SKILL F4-3200C14D-16GTZ Trident Z Series DDR4 3200 memory
Geforce 1070
Cooler master 620W PSU


I used the following settings in my BIOS:
I set my memory to DOCP.
CPU multiplier to 37
VDDR CPU offset to 0.11875
VDDR SOC offset to 0.01875
Load line calibration is set to High for both CPU and SOC


I am using AIDA64 stability test to verify that the system is stable, yet I get BSODs about 20 minutes into the test. CPU core temperature reaches 74 degrees but that's within the acceptable limit.

I've also tried 3.6Ghz and it's failing there also.

Can anyone advise if there's anything I else I can try to get at least 3.6Ghz for all 8 CPUs? I've upped the voltages for both CPU and SOC twice, didn't help, still got a BSOD. I don't want to raise the voltages too high.

Thanks in advance for your advice,
Scott.

What is the reported CPU Vcore while under load and as well the SVI2_TFN CPU Core Voltage?

The stock cooler is pretty good, but generally not for over-clocking especially if the case isn't itself well ventilated. With long-term stability tests it will become heat-soaked and left without thermal capacity to handle a processing load transient as it comes up in the testing algorithm even if the processor was reporting under it's max temperatures.

Hi, thanks for replying.

A BIOS configuration mistake I made after starting this thread has lead me to believe my memory can't handle the overclocking, even though it is 3200Mhz. For a stability test I switched off DOCP for my memory and set memory to AUTO thinking that maybe the motherboard wouldn't be so aggressive with RAM timings and be more stable. I left my higher CPU voltages on.

I ran AIDA and went out for an hour and a half. When I got back the test was still running. I was pleased it was still running fine with no errors. I then spotted the memory was running at 2133Mhz not 3200. I'm not saying the CPU is stable @ 3.6, as I've not run the test for 6 hours, but its lasting longer than before and so I'm hoping its just memory timings that need tweaked.


To answer your questions:

My max core voltage according to AIDA64's CPUID is 1.384V.

I'm not sure what application could tell me the SV12_TFN value, if you can advise me I will install it.

When I was buying the Ryzen I read a few articles saying the stock Wraith Spire was decent enough for 3.7 Ghz. I understood that for 4Ghz I would need a watercooling solution. Is the spire not safe enough even for 3.6Ghz?

Max temp my CPU is reporting is 76 degrees according to Ryzen Master.

Thanks for any advice, much appreciated.

HWInfo64 is the best utility I'm aware of for reading out the SVI2 parameters. The big difference is this: the CPU VCore voltage is the output of the VRM circuit. Sometimes that can be really high if it's not accounting for the losses of the motherboard traces and CPU pins.

The SVI2 data is what the CPU is reporting, through telemetry, as the actual voltage the cores are seeing. At least on my motherboard, I tend to think it's fairly accurate as I read the voltages (with a meter) at the base of the CPU socket and at the output of the VRM and they agreed with the SVI2 and VCore readouts in HWInfo64.

BTW: comparing the two help you gage the effectiveness of LLC settings.

Yeah, it's very dicey overclocking both memory and CPU as you never know which is causing the problem when it crashes. I like to get each stable separately first, then both together. Memory clock speed seems to also affect Ryzen stability too: I think that's because the infinity fabric 'overclocks' with memory.

The Spire cooler works well enough under routine workloads (which would include most gaming) under a mild overclock but it offers so little thermal headroom I'd not like to consider it stable for long video encoding or rendering projects. Also, you have to make sure the fan is running at pretty much absolute max and that is one screamer at that speed.
