3950x ETA

That would make sense given the verity of difference in performance in games between the 3900X and 9900K, according to HUB in 36 games that difference ranges from +4% to the 3900X to +16% to the 9900K and everything inbetween.
Some game are just more susceptible to AMD's Fabric Architecture than others.

I do think its great that if you want to put the time and effort in you can mitigate the performance penalty from the Fabric Architecture by tuning the RAM Timings and Sub-Timings.

Is not only that. Is the new IF how it operates and proven that manually OC it to 1900 gets great benefits even with stock RAM at 3600C16 or 3200C16.

On that here is the review, 9900K @ 5Ghz vs 3900X PBO + Auto OC. RTX 2080TI @ 1080P

Farcry New Dawn (Same as Farcry 5) near the bottom.

Check the bottom games, Hitman 2, SotTR. These are the games where the RAM speed made the biggest difference, and with tuned RAM, is wiped out. And in case of Hitman swerve 15% to the other side.

And Tomb Raider

From this video....

GN's slides are really difficult to decipher as they data dump you with masses of unnecessary info and then have incomplete info where it might be useful.

The top 4 on these slides are an unknown brand of RAM, i am assuming the same brand, one of them, the bottom of the 4 is 3800MT/s Auto Settings, where the BIOS will put the IF into 1:2 mode, one up is with 3800MT/s with the IF set to 1:1, next one up is 3800MT/s with Tuned Timings, the top one 4200MT/s with Tuned timings. All of them have the IF at 1900Mhz.

None of this is clear on those slides, but again its the manual tuning of the RAM timings that really matters.

Ah ok thanks

I can't, motherboard doesn't have that option.

How hard is IF overclocking on gigabyte?

I’m probably looking at the Gigabyte X570 Extreme if I grab a 3950x. I’ve got a 32gb lit of 3200 cl14 memory - hopefully that can overclock to 3600 or something as well

If you make sure SOC etc have the correct power settings seems 1900 IF is a great stable overclock that improves performance more than chasing 100mhz of the core speed.
Buildzoid has also similar break down on overclocking IF to 1900 and so does Linus.

Is it the 8 pack ram? as i have cl 14 3200, and got it to 3600mhz with 16.15.15.15.32.48 timings with 1800 IF, i would love to OC the IF to 1900 but everytime i ask here how to do it , no one has a word to say

To achieve this utopia, you should clock the IF before anything else, leave RAm at native (loose) timings and see if the CPU IPC will do 1900. I reckon, wait for this new incoming BIOS, THEN see what's what.

I have had 1900 if, and also 3800 ram, but not at the same time

I have the IF running at 1900mhz with RAM at 3800mhz all day long on an MSI X570 ACE, on the previous bios is wasnt stable and every 15mins or so my PC would just shut down and restart, on the current bios though it was fine, thats why im a bit weary of flashing the latest beta, I really cant be bothered to go through all my settings again if it turns out its not stable again at those speeds.

As for overclocking it, its just like overclocking anything else, up your SoC voltage a little bit, dont go any higher than 1.100v, I get a warning at that voltage stating that PCI-e 4 will be reduced to PCI-e 3 speeds with SoC above 1.100v, and even though im not running any PCI-e 4 devices, you still want that link between the CPU and Chipset at full speed to utilize the most bandwith, thankfully mine is stable at 1.05v, so then just manually bump the FCLK upto 1900mhz and test, if you get random reboots, back off a bit to find your stable sweet spot.

Nghtmare · 8 Sep 2019 at 09:25

I had my IF running at 3838Mhz before with BCLK set up and managed sub 63ns latency. It depends on the CPU how far you can clock it, the BIOS does play a factor but if your CPU cant handle it, there is nothing the board can do.

Not looking like today for release

New week or two, there is a BIOS on the 10'th to fix boost clocks.

That is the day they are going to send it to board vendors, add another 2-4 weeks until they implement it :/

so we could be looking at the end of september then

Yeah i wouldn't expect them before then.

Buffalo2102 · 8 Sep 2019 at 13:14

I've got IF at 1900MHZ and RAM at 3800MHz CL16 (used DRAM calculator). I've forced the UCLK to 1:1 aswell. Voltages are all on auto except I've raised the DDR voltage to 1.4V.

All solid as a rock, no boot or other issues.

I don't know "8 pack ram" is. It's this kit: https://www.corsair.com/ca/en/Categ.../Vengeance-PRO-RGB-Black/p/CMW32GX4M4C3200C14
