Every single one of my Intel products has zero issues hitting max boost on the rated number of cores. My stupid laptops i7 5500u will sit at maximum boost until the cooling on it hits 90C. The Xeon in my server will float cores up to max boost as needed with out issue, so I do not know what systems you are looking at or comparing, but I have never seen nor heard of the issue you describe.

It just goes to max clock for short period of time and not even on all platforms. If it stays at max boost clock then settings are not standard/auto. Part of my full time job is to configure and sell computers and I simply never see max boost on branded laptops/servers and fresh OS without changes. The same if servers are in production phase then they never go to max boost even if performance mode is enabled in BIOS. Load balance won't let it run at max turbo simply because there are always processes in the background so single thread just never happens. That's for standard settings on computers where you can't really change any settings in BIOS. You can however force max clock by limiting active threads in OS or use soft which is forcing max clock. OC series motherboards have often additional features which are keeping turbo at max but not regular boards.

Software OC has been regarded as garbage up to this point and only time will tell if this software is garbage also. What is interesting, I think, is that most of the bios options are present in the software

Edit: hit send accidentally :)

.... Since more bios options are in the software, I suspect that the bios is going to be less fruitful for tuning than it ever has been before
 
On the other side, I've found software OC to be somewhat helpful in optimising settings faster than I otherwise would through many reboots and bios changes, but I would still set my 24/7 OC in the bios and not rely on software to do it. I still haven't got used to the Crimson interface yet, and it looks like they're using similar for the CPU OC tool...
 
For benchers OC software is a must. Can't usually boot to windows full out and needs to be taken higher in OS with software. Hopefully it's decent. I'm sure that the board makers will also have their own versions
 
Has here been official mention of native supported ram speeds? To pick some mobo claims at random...

The Asrock link is particularly interesting, as they have a table indicating how many modules (and what rank) you can run at what speed... is this a mobo limitation or a Ryzen limitation I wonder?
 
Well some things never change; looks like AMD is once again possibly underestimating power usage. Can't say I'm surprised, the hottest most temperamental chips I've ever overclocked have always been AMD. I figured the lack of SFF or mATX boards didn't bode well and it looks to be correct.
 
To be honest I am not surprised you need a good board to drive these new cpu's. Back in the day if you wanted a guaranteed overclock you needed a good board. Since the second or third gen i7 came out, users have been treated to higher overclocks that come relatively easy. If I can recall, the first iteration of the first generation i7 didn't clock that well either.. I think somewhere around 3.8-4.1 is where they topped out. Playing with P3's, Athlon xp's, A64's, I've found lower end boards almost always give out. And sometimes the good ones do too lol. :thup:

I only moved to intel because I was sick of motherboards crapping out lol. Abit and Asus I'm looking at you! Conroe came out and I haven't looked back until recently.

I linked some of that some time ago. Max is 3200 on 2 memory slots for most higher boards. ASUS CHVI has 3200 on 4 slots. ASRock has max 2666. I wonder if it's real max stable or manually can go much higher. Most Z170 motherboards have also 3200 as max tested.
If IMC is scalling good with cores then even 2666 can be good. 8 Intel cores offer higher memory bandwidth than 6 cores and at 2666 you can see 50GB/s+.

2 cores 4 threads on a 5500u. Pretty common to use both at full speed and they will sit at boost until the tdp envelope is exceeded. My 12 core has no issues hitting full speed on random cores as needed. Why you think it isn't working when it does that is beyond me. That's how turbo works...
 
One thing I did notice from that LN2 pic is that the BCLK was 140ish. Only a few reasons to do that with unlocked multipliers

Bart, are you seeing much real life performance increases from 2400 to 2666 to 3200 or is it mostly just in synthetic benchmarks?
 
It's in many benchmarks more or less, all depends on platform. In games etc there is barely any difference but you will see difference between single and dual channel even on laptops or simple workstations.

Actually I have a Dell Precision 7510 with the i7-6920HQ (2.9Ghz) CPU and it does stay at a sustained 3.4Ghz for extended periods of time at least when I'm docked, and even in my lap sometimes. It can be done I just dont think it happens that often because of thermal limits are hit too often. Thankfully my chip is cool and get a nice spead perk out of it.

I concur: my old 3630QM [email protected] (from 2.4GHz) on 4C/8T for hours under P95 (it never hits 90c...)
