AMD CPU with NVIDIA GPU?

[71st_Mastiff]

I got them to work after doing the auto setting and they set to 1.35v, and the motherboard (MSI MPG, z690 WiFi DDR4 Edge) turned on some sort of "game mode initiated"? I don't know what that was about, it seems to be stable for day 1 so far. and DCS World hasn't crashed in the Afghanistan map either. I haven't tried MP yet.

sorry for hijacking this thread, but it looks like Ill be going after; 20 years with green team, back to team red. intel has left a bad taste in my mouth after there i9 14900k fiasco. and seeing all the hype about the AMD 9950XT and married with a NVIDA GPU, seems more efficient now.

change my mind?

from this channel for reference.

as now; that I'm in my late 50's, looks like this may be my last build.

I have 35 years in building computers, not a novice, I have seen this tech change over from ATI, to AMD, NVIDIA and other GPUs that where in the mix.

at 15 in high school when computers classes and coding where introduce in school, to which I think they need to do again, computer science classes.

I suppose you mean the 16-cores/32-threads AMD Ryzen 9950X (there is no 9950XT model in their lineup).
It's not worth going to that from an Intel i9 14900K, because they're direct equivalents, i.e, it'd be a side grade at best, and an expensive one at that.

There's the upcoming AMD 9950X3D 16c/32t later in March (next month), same chip as the 9950X but with one of the two CCDs making use of 3D V-cache.
Maybe wait for in-depth reviews of that, and see if it's worth the big money and all the hassle.

I have my doubts that it's worth leaving behind what you already have for it, but I'll reserve judgement until that's out and thoroughly tested.
Notice also that you have a 128GB DDR4 based system. Meaning, you'd need to at least buy the CPU + Motherboard + RAM and, being a completely different architecture, it's basically a whole new system being built from the ground up, all over again.

Personally, and looking at your signature, I would keep that system (still very, very good) as is until 2026 or so, when the following new generations of Intel (16th gen) and AMD (Ryzen 10000 series?) chips should be announced, then later released. 
But then I don't suffer from FOMO (a very common affliction in these forums). Meaning... that's up to you. You may be interested in changing platforms right away if only for the novel experience, and there's nothing wrong in that if you can spend on it.

I see that you have a Pimax Crystal for VR. 
So, all that said, and if that much, it wouldn't be a bad idea to look for an RTX 4090 24GB (last units in stock, or used in mint condition) if at a good price.
While your RTX4080S is a great GPU for that task, you'd notice a bigger jump in performance with that swap alone, than with the new CPU + Mobo + DDR5 combined investment.
And yes, you'll notice the new RTX 5090 32GB but it's outrageously expensive for what it is (totally absurd, and a fire hazard waiting to happen), it can not be recommended.

yesterday all day gaming and all ran fine with those setting you gave me.

well I been testing the timings you gave me and today the first OC failed crash occurred.

 

"DRAM Frequency ---- 3200 (decrease to 3000)"

so now I'm at 2600, 

 

I agree on wait until 2026 or 2027.

Well after more windows crashes, and nt.dll, page file crashes, so put the 64gb back in restored from last weeks, and all ok again. So far. 
im going to give up on the 128gb. And just stick with the. 64gb.

hmmmmm....  
Have you tried booting the PC with just one stick at a time, with XMP profile loaded in BIOS? It could be that one of the sticks is faulty.

I've heard inumerous times that 4 sticks of RAM of such high-density (4x 32GB) can be complicated sometimes, depending on specific module and vendor (SK Hynix, Micron or Samsung) and motherboard / BIOS version.

But if the memory kit is advertised at such speed/timings (3200 CL16-18-18-38), and seeing that your motherboard (MSI MPG Z690 EDGE WIFI DDR4 ?) is listed in its QVL by GSKILL themselves, then I think it's worth contacting them directly for assistance, via email.

• GSKILL support:  https://www.gskill.com/techsupport
   
• Your RAM QVL in the model's page:  https://www.gskill.com/qvl/165/166/1582537062/F4-3200C16Q-128GTZR-QVL

Tell them what mem kit you have, what motherboard you have, what you already done to try make them work (and still no luck) and ask for their help.

They're not fast in answer (i.e, it can take time to get a reply from them) but they're usually very helpful, and I don't recal a single time GSKILL didn't stand behind their products once contacted.

PS: not related but FWIW, I have 4x 16GB of Micron 3200 16-18-18-36 1.35v (it's two kits of Crucial BL2K16G32C16U4B, for 64GB total) and it's been working overclocked at 3700 17-19-19-38 1.40v (done over XMP base profile) for nearly four years now with two different motherboards - first on MSI Z490-A Pro, then ASUS Z690 TUF Gaming Plus DDR4. 
MemTest, Karhu, Y-cruncher, etc, it doesn't matter, always passes with flying colors, rock solid reliable.

The devil is in  the detail  and DDR4 does not have DIE's large enough to make  32GB module with just 8 Dies, each 32Gbit, THERE ARE ONLY 16Gbit ones and those are not Samsung B-die, those only do 8Gbit Dies.

So, whatever option in DDR4 realm you opt for to get a 32GB module, you ALWAYS end up having "16" 16Gbit non-B-Dies on that module...and that 4 times !!

This is the heavy load to lift for your IMC and it will not do it with fast settings at all, 99,99% sure...it may make it at JDEC 2133/2666MT/s default settings

and that is what Intel/AMD usually also state in their papers. 

 

To have fast and stable 128GGB you need to move to DDR5 and WAIT until 64Gbit Dies are available, they aren't yet either !!!   32Gbit dies are out, so you can do 64GB with 2 modules, each module only holding only 8 DFies each...making it so much easier for the modules, IMC and traces and what not else to achieve speeds beyond the DDR4 realm.

Again, 128GB is still a bit away, even on DDR5, if you want fast, reliable XMP/EXPO capable modules with 8 Dies only.

 

I am happy that my 4 modules, each has 16 Samsung B-dies, 16GB, 4 of them, total 64GB, takes the beating of heavy o/c and heavy overvolting for over 2 years now, respect to Samsung.

There is no such thing as B-Die   FTW !
