I probably would these days. I'm not that into overclocking anymore and feel like its not worth losing other features of the cpu over. AMD and even Intel to an extent run their chips a lot closer to the top overclock to start with making the whole exercise kind of a waste of time IMO. If you like overclocking for the sake of overclocking I understand that but it looks the money saving part has been monetized out of existence to me.

Stock for me too. I value stability and efficiency over performance these days (within reason), and can't say I have ever actually noticed a difference overclocked vs stock except when my PC doesn't work right and I have to mess with something in the BIOS.

I still enjoy the process of it but if the chip is fast enough, as looks to be the case with the 2700x, I would just turn it back to stock, maybe with a small negative voltage offset.

I also doubt I would overclock it, considering my experience with my 1700x and my B350 VRMs. Though I would probably use Precision Boost Overdrive.
The main reason for overclocking with the old Ryzens was that pretty much all games were stuck @ all-core turbo clock, which for 1700X is 3.5 and for 1800X is 3.7. With the newer chips, Precision Boost 2.0 should get much closer to the theoretical OC maximum.

I expect negligible difference in gaming when using Precision Boost Overdrive vs manual overclocking. Sure, you would get slightly better scores in very threaded benchmarks, say Cinebench, but in gaming, where most of the threads are not constantly 100% loaded, I'm confident that PBO will net the same performance with considerably lower power draw/heat.

I'm in the same boat. I'm going to get the plain 2700 and a decentish board and call it a day. My last two Intel K units were complete clangers. My 3570K only had a few 100MHz OC w/o volt increase and it died before warranty was up. Intel sent me a new one, though.

My 4790K has such a horrible IHS gap that it hit 100C at 4.4 GHz (no volt increase over stock) in Prime95 with a Noctua NH-D15 running at full speed. It is almost dead, having spent most of it's life at 4.4 all cores with no extra volts. A few weeks ago, it hard crashed and I had to set it back to stock which is 4.2 GHz max across 4 cores. Now it throws errors on LinX and Prime (at 4.4 all cores) and won't accept any volts increase. I'll send it back and get a 2700.

Does anyone else think these slides are fake? I kinda feel they are...

I am on the fence about getting a 2700 and board, as the current 1700 has 4 x 8GB at 2400 low timings.

Unless RAM prices drop and 2 x 16GB kits can be had for a reasonable price. :(

Overclocking the Intel has been really easy while maintaining idle power saving. It doesn't seem to be the case with Ryzen so I wouldn't bother. On top of that 2700X is likely pretty much maxed out out of the box.

Anyway its only a few weeks. Just wait and see how the final specs and performance reviews turn up and make a decision.

Pinnacle Ridge AGESA (which is rolling out to all AM4 motherboards these days in preparation for Ryzen 2000 series launch) has finally fixed pstates, you can set them to whatever you want in BIOS without breaking any functionality. Then you can enable cstates (should be enabled by default, but it doesn't hurt to force them on) to let the hardware properly idle, and use an appropriate power plan in Windows.

Here's the result:

kK7wkRr.png


  • P0 is set to 3.8GHz and 1.375v (no LLC, droops down to ~1.31v under P95 AVX small FFTs load)
  • vSOC is set to 1.1v to support 3466MHz memory speed, vDIMM 1.425v
  • Ryzen Balanced power plan with CPU idle speed set to 0% instead of 90% because I'd like to let Windows use the entire clock speed range

See, proper idle (hwinfo managed to "detect" P3 at 0.4v) with overclocked speeds. You could more or less get the same result since launch day on the C6H with voltage offsets and other workarounds, but thankfully now it's much simpler and can be done on every board as far as I'm aware.



Anyway, having cstates enabled lets Ryzen take control of power management all by itself and that's what you want to do in this platform. Entering OC mode doesn't disable power savings.

I'm old fashioned and that's why I take that 90% idle down to 0%, but it's not needed.


Obviously, power management this advanced is miles ahead of any faildozer part ever made, and Pinnacle Ridge is probably going to make even more improvements in this area.

It seems questionable that AMD would take Pinnacle Ridge dies and disabled half the cores so that they can be sold as quad-core parts, now that AMD has Raven Ridge dies.

Raven Ridge dies are unusable to replace those SKU's due to the PCI-E differences. They're also not going to be as fast as Pinnacle Ridge per clock and per core. Memory overclocking is also inferior to Pinnacle Ridge.

They're just clearing stocks at this point. 1300X and 1500X are probably the least popular items in stock right now, so they want to get rid of them. The 1600 while popular, was produced in the greatest quantities of any CPU in the lineup due to popularity, so it's staying for now for stock clearing.

Also, depending on board mfg, you can OC and still have all the power saving.

I can only speak about Gigabyte (as a Gigabyte rep recommended this on Reddit), GA-B350-Gaming 3; if you use a 25 MHz offset, it will auto down-clock and all that.

I think my 1700 is set at 35.75 as the multiplier and all cores will clock ~ 3575 MHz under load and do power saving when idle.

I don't think he was talking about labeling an RR as just a 1200-1500x. I think the point was that by having a cost effective APU, with 4 cores, AMD target those for low end sales and forgo offering PR in a 4c solution. You would lose 8 PCIe lanes but gain a competent iGPU. Though since it caps out at 2400G I would suggest that they are leaving themselves open for a 1500/1500x option as the lowest end PR.

If you OC to "save money" then you get chips like the 2700 and cross your fingers.

I wonder how well will IMC perform... could we finally get 60GB/s on dual channel for stable 24/7 OC on average?... Well I am certainly not upgrading from my R7 @ 3,8Ghz @ 3400MT/s, but this looks very interesting.

I don't care what it looks like, but what it performs like. Hopefully some of the 2700X reviews compare the Prism to a popular Air coolers.

Seems perfectly logical to me. Thats almost exactly like the other HSF's that AMD has done lately. And the rest of the industry.
