[Official] Intel's 9th Gen CPUs & Motherboards Discussion Thread

[Phen8210]

the only board failure i ever encountered was from biostar, twice as well.

The z390 aorus line has plenty of usb ports at the rear io. For asus, need to get the rog line to have that much. And that is usually more costly than aorus. For msi, need to get at least the ace to have similar number of ports. For asrock, need to look at the taichi line

Yea I was considering the Z390 Aorus Ultra.

I wanted to swap over the MSI MEG ACE but it has no iGPU out! Does that mean that Intel Quick Sync cannot be enabled? Reddit says MSI didn't even build VRMs for it.

I'm still worried about Gigabyte reliability though.

Asus is just bad value in general and I've heard that the RMA rates are low because Asus customer service is a PITA.

Z370 Aorus Ultra has VRM temp issues so you might want to check whether the Z390 version has fixed that.

UrGh. VRM issues is a dealbreaker

Actually the z390 ultra is replacing the z370 aorus gaming 5. For z390 gigabyte no longer use numbers in their product line.

Not sure about the vrm, but gigabyte mentioned all cores at 5ghz+ for their aorus z390 line.

****. Got TLDW(atch) version or not?

Considering Aorus Ultra vs Maximus Hero XI

The actually summary of that was a pretty sad state of the review/youtube review community. Even on last year's 8700K launch.

More or less since the Sandybridge platform, except the voltages have changed noticeably since. The platform was in this particular manner had values PL1, PL2, PL3, PL4, Tau for the power limits. If unsure how it works, see chapter 4 of the processor datasheet linked below..

The takeaway is that reviewers don't even sanitise the PL and Tau values back to Intel defaults when it is obvious that retail and review BIOSes contain a lot of "factory overclock/BIOS cheats" to run the CPU's beyond factory rating.
For example, (hypothetical) Gigabyte can configure its "auto" PL1/PL2 to 4095W, Tau to 8 seconds. The average joe would take that auto as the "default Intel spec".

In other words, most review power and performance numbers "stock" and "OC" are just "light OC" vs "moderate OC" without Intel stock numbers. Like the MCE debacle that was mostly a result of lack of platform understanding from many reviewers with the exception of a very few. Like "The Stilt" that still publishes very well sanitised performance and power numbers, BIOS cheats removed.

Reviewers that claim "stock" benchmarks and do not dial in the following values (as per Intel datasheet) should just redo their benchmark numbers.
8C PL1: 95W
8C PL2: 95W * 1.25
Tau: 1 second

you mean the tech community hasnt learn anything since MCE became a thing many, many years ago

right. got it.

personally i dont give a flying cat about whether the processor is reviewed at intel's stock or motherboard vendor's stock. all i really care about:

performance @ 3.6ghz (avx2 load)
performance @ 4.7ghz (nominal all-core boost)

but based on what i've seen so far, can safely say most reviews' numbers are untrustworthy at worst. gonna rely on what i feel is the most correct number and base my upgrade decision on that

 

[Koenig168]

Excellent commentary. The i9-9900K runs a lot hotter than some reviewers think.

It's true details were out there in 2011-2012 but uhh... where are we today where reviewers are still having trouble removing bios cheats from either platforms?

Also, good video from MSI engineer Toppc Lin

So I wasn't wrong in advocating for OCing with independent per core multipliers (as per intel default), SpeedShift & Adaptive/Offset mode for a good mix of strong Single Thread bursts and low moderate use & idle power.

was about to say "amd got bios cheats meh?"

then i remember pbo

*laughs in 1700*

so can i safely say that LTT set of numbers and observed oddities is actually the closest to the stock performance of 9900K now?

BEWARE: REVIEWERS DISHONEST ABOUT 9900K TEMPERATURES EXPOSED

So ltt is actually a good reviewer

You go check the stilt profile on ocn, at forum, bbs iotech-fi? The guy that fixed our RX480 breaking pci sig specs? He always presents facts backed by data

Also, "good to knows" on picking motherboards that'll better saturate your skylake IMC if you're running b-die memory from Toppc.

Worth noting that most 4-layer PCB boards (like strix/prime) cap out around 3733 for Z370. The aftershock pro4 (4 layer) was the cheapest Z370 board that supports RAM at CPU speeds

Assuming no material change & by extension, the Extreme4 / Phantom 6 PCB should be a very good board for attempting 3866-4133MHz C16/17 gsat stable on single rank Non-RGB B-die

How should i read this chart?

Very tempted to build a new desktop. Or get apex 15 from aftershock/ msi gs65 stealth/ razer 15. Budget would be around 3k

The motherboards with higher quality VRMs are at the top of the chart. Better VRM provides more stable power delivery which helps in overclocking.
