Guys, I need your advice .

My mobo is a Asus zROG Strix-A WiFi D4 with 2x 16 Gb DDR4 GSkill 4266 17/18/18/38 memory.

The 12900k @ 5.3 was running fine with memory running at 3800 MHz 15/15:15/32.
Any higher would not work, so the CPU’s memory controller caused that.

The 13900kf has a memory controller that will not let the memory run any faster than 3200 MHz …..  I have done tests, read all about it on the IN. Yesterday I even returned the 13900kf and they gave me a new one. 
The outcome is the same .

So before returning the 13900kf and buying a second hand 12900k, what do you think is faster :

12900k @ 5.3 plus 3800 MHz 15/15/15/32

or

13900kf @ 5.8 plus 3200 MHz 13/14/14/32

Upgrading to a DDR5 mobo is something I will do perhaps the end of next year.

All you suggestions are welcome.

 

13900k will be faster. Memory speed will barely help games at all. There are people that will argue the opposite, but there are hundreds of benchmarks on the web showing how little difference there is between 3200 and 3800. The ones that show otherwise are suspect.

Go with the faster CPU.

Why doesn't memory speed make more difference, because everything these days is rendered on the GPU's memory.

That is why the only real difference is the buffered cache between the GPU's memory and the memory itself, which almost always results in less than a couple fps gain, unless a particular game has a serious caching issue (still it's not usually that much).

Thanks 👍

Just got about the same message from a known Dutch tweaker.

End 2023 I will buy a DDR5 mobo + DDR memory and then use the 13.900kf with that combo.

The DDR4 mobo + menory + second hand 12900 will be used in my left view client.

Now back to flying.

I'd say definitely keep the 13900KF. IMO a faster CPU will have a much bigger effect in MSFS than faster RAM.

I am not sure I can comment any further, the forum-hijacker-police is watching, but you could still sell your 4090 before they become available in 4 weeks 😀, and they will have FSR3, will have to see how that compares to DLSS3. this will be another exciting weeks of benchmarking and good to finally have a strong competitor to NVidia.

$ 899 and $ 999 in another 4 weeks. about half the price of the 4090 !!!

I just read an article by rockpapershotgun (perhaps the same that Turbo referred to) and what AMD is releasing Dec 13th is indeed impressive. The cards are much more affordable, they have a lower TDP and a DLSS3 similar technology (but early to tell exactly what the details are here). Unfortunately FSR 3 won’t be available until early 2023.

Speaking of, anyone who picks up an RX 7000 series card won’t have to worry about needing an RTX 40 series-style power adapter, as they’ll take your PSU’s regular 8-pin power cables as they are.

These news are promising for those looking into an all AMD build with the AM5 platform and perhaps a Ryzen Zen 4 7000-Series 3D V-Cache CPU sometime early next year.

if I may disturb Master Captain for a moment - might that also work in a mixed salad of Intel Metro Lake and AMD RDNA 3 ?.

the main issues to wait for are:

FSR 3,

how stable are their new drivers and then

CapFrameX comparisons re. final fps.

You might not like the added fan noise, but as long as you lock it at 60, it probably won't be that bad. The previous gen can take a LOT of heat before they break, some people were hitting 105c before frying them (after disabling the protection). That said, I don't trust any temps over around 85c on the AMD's, too much residual heat, and I prefer to keep it in the 60's while gaming (70's max), 80 as more of a peak temp to shoot for.

It's unlikely to be as fast as the 4090 though, but it might make sense if I can get comfortable Ebay'n my 3080...

My main concern will be is it still going to constantly reset my refresh rate, and is TDR settings and (driver timeouts) are still going to be less robust than Nvidia?
Nvidia handles driver timeouts differently than AMD, and this can be a headache in third party rendering software (like substance painter or Quixel), you have to increase the settings and it still sometimes lags more than Nvidia's do.

So it might not be a perfect solution for me, but I may do it just for the fun of it.

hmm, i do not use Lasso... just thinking if i changed something in the Bios despite xmp and overclocking profile.... but it workes with those settings in DX11

This is th error message i get:

I googled for the module WwiseLibPCx64P.dll and CTD, and came across a possible solution in the official forums:

Seems to be related to some drivers for your onboard sound card...

I'm sure mixing Meteor Lake with a Radeon would be fine. I don't think I've ever owned a Radeon GPU though - heard there's been some issues with their drivers here and there?

Will be very interesting to see the first RDNA3 reviews. Perhaps the RX 7900 XTX will be competitive to the 4090? Then feel free to ridicule me for being an early adopter with the 4090 😉

1) unfortunately not, early calculations predict some 15%-20% slower than 4090, and we don't know anything about their FSR3 yet.

2) no, the only thing I am angry about Master Captain is that he was faster than me on launch day and stole my precious from that online store.

the best about the RDNA 3 for me is that it may help reduce and accelerate reduction of 4090 prices, eventually down to MSRP.

Edited November 4, 20223 yr by turbomax

We won't know for sure for another month about the speed, but there may be some cheap deals on these cards by early next year.
You can generally expect to find any AMD on sale for much less than the MSRP at any time there is enough inventory.
AMD's go on SALE way more often than Nvidias do, so the price is a lot less if you shop around.

Right now you can pick up an XFX 6900xt brand new for $650, which is the same as the 3080 TI in MSFS. Sapphire and XFX go on sale a lot, Microcenter often blows them out sometimes $200+ below MSRP.

Whether or not this trend will continue, we will see.

thanks for this. I found this thread too but this is not helping me.

If is reset MSFS to default (so not the "normal reset option, the one below reset) i can start and play in DX11.

Sometimes DX12 is starting one time but it mostly then crashes within the sim and then the Sim doesn't start ultin i do the first dcseribed procedure...

No clue what causes this. I did a complete reinstall of my PC and until a certain point the sim runs in DX12 but then from one moment to the other the crashes start even though i did not install any other program or driver.....

i think i nailed it down so far. DX12 is causing strange effects. if i switch from fullscreen to Window i get an "your graphicscard encountered a problem".

As there are only 2 Drivers available for the 4090 i cant test earlier ones...

In DX11 the sim runs really smooth.

What gives me problems tto is FSLT. As soon as the planes are moving i get stutters on a 1 second basis. no joy to fly. Does anyone of you know a solution ?

Thank you, Carsten
