Question 1700x safe overclock?

[ohio_buckeye]

So I'm running this system

Ryzen 7 1700x
Wraith prism
ASRock AB350 pro 4
RX 580 8gb. Depending how much I continue to use my PC to game, I may upgrade this later

16gb crucial ballistix ddr4 3000
Cooler master mb511
PowerSpec 750 watt bronze from Microcenter(seems to work well I think it's rated about 62 amps on a single 12v which I'm thinking is overkill)

I purchased the wraith prism second hand to replace a different air cooler I'd been using.

Applied fresh Arctic silver 5.

Went in bios, set speed to 3800mhz, disabled all power saving, and set voltage to 1.35. As I understand, 3.8 was the max turbo core.

It passed Intel burn test with a max temp of 74C when it was under 99% load. 69C in cinebench r20.

From what I'm reading, 75 is the max safe temp for these. So I'm thinking that I'll just leave it here. Should allow a couple more games, and more later when I get a better gpu. Figure I'll use this to hold me over until ryzen 4000 comes out.

For reference, my friend with a stock 2700x benched his system on cinebench which shows him just behind mine with the overclock. Thoughts? Just making sure this is a safe overclock/temperature. My thoughts are yes, but of course many of you know more about overclocking than I do.

You have wrong motherboard and CPU cooler for any serious OC. You have surprisingly good temps, TjMax and with it "safe"temp is 90c. Make sure your VRM is cool though as it's not meant to push much power. That should be your main concern.

Was trying to see online, what is stock voltage on that cpu? May try bumping the voltage back to 1.325 to see if it's stable and if that drops temps slightly. Not looking for a crazy overclock, just enough to hold over until the 4000 series lands in a year or so.

There is no 'stock' voltage since voltage varies in normal use by design. But when Ryzen 1000 came out AMD indicated that 1.425V was the highest you should operate at 'sustained' and 1.45 is the max it should see 'normally'. That was instructions to overclockers, of course.

Most people tried to stay under 1.375 V max when overclocking. But some motherboards just can't furnish stable power with voltage that low when put under stress with OC's around 4.0Ghz so they have to be bumped up more, that's where the 1.425-1.45V absolute max becomes important to pay attention to. Your board has a 3-phase VRM so it just won't put out clean, stable power under heavy load so you may have to tend to the high side for voltage. If the VRM starts getting hot just put a fan blowing on it.

It's also important to follow the correct voltage reading: it's STI2 TFN as reported in HWInfo64. BTW, I ran my 1700 (not a particularly spectacular silicon example) at 1.4125V for about 2 years solid at 3.95Ghz starting in a B350M Mortar then B450M Mortar. It was prime95 stable and I did frequent h.264 video renderings that ran temps in the 80's for long duration. It was a solid system all the way until I went to the 3700X in it now.

AMD specified max temps for 1700X is 95C - https://www.amd.com/en/products/cpu/amd-ryzen-7-pro-1700x . 75C is generally where Ryzen starts to throttle it's boosting so when manual all-core overclocking that's somewhat irrelevant.

 

[ohio_buckeye]

Cool. So I should be safe where I am. I may see if I can go a little further. But at 3.8ghz, I'm pretty happy with performance there. I know in cinebench r20 it was just ahead of my friend's stock 2700x, so I was pretty pleased about that.

This might be a silly question, but I have Christmas money left. Any value of grabbing this board? Found one open box at Microcenter for about 68.

Was looking and vrms seemed like they might be more stout.

Or what is the story on the Asus ROG strix b450-f gaming

I don't think it would offer you anything better than what you have now. Don't be fooled by all those inductors, it's really just a 4 phase VRM with parrallel inductors to fool you into thinking it's an 8 phase. The FET's for one entire VCore phase aren't even under a heatsink.

While your B350m Pro 4 has a 3 phase VRM it's a very strong 3 phase design with 4 FET's (2 hi-side and 2 lo-side) on each phase and all of them under a well-finned heatsink to keep it cool.

I'm pretty sure ROG Strix B450-F Gaming is the same as the Aorus M, with parralleled inductors and 3 FET's to a phase. But in this case all VCore FET's are under a heatsink. Even so, I really don't think it would offer any better performance than you're getting. You'd have to decide whether aesthetics or board features make the purchase worth it to you.

 

[ohio_buckeye]

Good deal. Sounds like I'm set for a little while anyway then. I have been wanting to play the new Jedi game. Maybe now is a good time to purchase lol.

 

[ohio_buckeye]

So a little more tweaking. Left clock speed the same at the moment. But dropped the voltage to 1.325.

Numbers from cpuid hwmonitor

CPU Max temp 69C(idle at about 32)
Main board max 26C
TMPIN5 53
TMPIN6 26
TMPIN3 40


Voltages per hwmonitor again

CPU VCore 1.312
VPPM 2.544
AVCC 3.328
3VCC 3.328
12v 12.302
VDDR_SOC 1.104
VIN7 0.944
VDDP 0.280
1.8v 1.864
VIN11 1.272
5v 5.088
Chipset 1.072


I don't know exactly what all the sensors are, but max package temps at 1.325 volts 3.8ghz are down to 69C.

Fairly happy with 3.8ghz, but sounds like this CPU may have a little more headroom.

It did not like 1.3 volts, got hard freeze during Intel burn test. At 1.325, it passes 10 passes of Intel burn test standard at 99% usage on all cores. Thoughts?

 

[ohio_buckeye]

Also, ran cinebench r20 and am getting a score with nothing except Windows defender running of 3793 multi threaded.

Single core is 385.

Most 1700's were (are?) good for 3.9-4.0Ghz at 1.350-1.425 volts. 1700X's, being a bit better binned, should be able to hit the same clocks at somewhat lower volts. But pushing beyond 4.0Ghz is extremely hard, with geometric growth in voltage demand and heat output for every 25Mhz.

I'd strongly suggest ditching HWMonitor and go to HWInfo64 for a monitoring program. HWMonitor's VCore voltage readings for Ryzen processors has always been incorrect, sometimes laughably so. In HWinfo, look at the STI2 TFN voltage.

Also look at Tdie temperature, which is offset from Tctl for all 'X' Ryzen 1000 CPU's. Tdie is the more correct as the temperature offset for Tctl is there to facilitate cooling to help with Ryzen 1000's boosting algorithm

 

[ohio_buckeye]

Thanks for the info. I do actually have all the boosting etc turned off in the bios. So it's 3.8 at all times from what I can see.

 

[ohio_buckeye]

Thanks again for all the help. Looks like at least on this board, the I'm going to get is 3.8. Bumped it to 3.9ghz but system froze during Intel burn test. Bumped voltage to 1.35, but system still wasn't stable so backed off to 3.8 at 1.325.

TBH, tried hwinfo and didn't understand everything in it. Just a lot of information though. But did install ryzen master just for monitoring, and it was agreeing with the temps I'd been seeing. I could probably try to go up to higher voltages, but even if I got 3.9 or 4ghz, don't know that extra voltages/temps would be worth my gain, and can't see buying a new board for only another 100-200mhz. So I guess I'll let it sit here until I upgrade. Upgrading from my RX 580 is probably the next move once I save up a little $$.

At 3.9G I'd at least try 1.425V since it is a safe voltage for Ryzen. Try a test, see if it's stable for 15-20 min's and how temperature behaves, then reduce a couple notches and try again for stability. Repeat that, lowering volts a couple notches each time, until it crashes again then go back up one or two and try a long-term stress test for at least 2 hours.

Also, did you set up a fairly aggressive LLC? Simply put, LLC lets voltage stay low when processor is at light loads but increases it under heavy loads when it's needed. A more agressive LLC means it increases VCore more for a given processor current draw.

I suspect you'll find it stable about 1.4-1.412V but you're far more likely to be temperature limited since you're still using a Wraith cooler.

Look at the sensors in HWInfo. It's set up in a number of sections, so scroll through to the section on the CPU and look for a line reading "CPU Core Voltage (SVI2 TFN)". That is the true core voltage internal to the processor, you may be shocked to find just how low it goes under stress loads. And just above that are two or three lines for temperatures, look at CPU (Tdie).

If it turns out to only be stable at 1.425V you can always back down clocks from there until you get to where you're comfortable, but at least you know what margin you're leaving on the table. And actually, I think your real problem will be temperature in long-term stress tests. Wraithe's just weren't enough cooler for 1st gen overclocking.
