Yes I use the KVR0Y antenna, it's for M17X R4 and it fits in the backside of the top lid.

Yes, it should be able to do at least 8000 C36 and likely C34. My X870E-E Strix was able to and my MSI B850MPOWER is able to do 8000 C36 with a 48GB kit. It will depend on the IMC and memory modules as well.

Okay, I’m going to try that bios! And @electrosoft I may try another 9950X3D2. If I’m feeling up to it. Memory tuning is very fun. But I learned that it does not help much in real world gaming performance, I suppose IPC is the real king for high fps and pushing fast GPU’s. My Xeon w3175x is a memory performing beast. When I would run only 6x16GB (96GB total) I can do 1T stable, and this does like 172GB bandwidth and 45ns-46ns latency. And it just cannot hold up to anything modern with the words X3D even with a single stick of DDR5 4800 lol. It’s a powerful rig, and still did well in many titles especially those more uncommon “Well Optimized titles”. 😂😂😂 These X3D chips are ridiculous in gaming. I did not realize how many CPU limited games I do play. Almost everything is CPU limited with a 5090 Astral, even with 4K. Rust, Oblivion, Ark, blasting some crazy frame rates with 9950X3D2. @Mr. Fox Are you thinking my Dark Hero should also run 8000c34 just like your Apex can?

Still respectable performance for such an old (and very affordable) GPU. And, DDR3 quad channel is on the heels of a modestly tuned DDR5 system.

What BIOS are you on? If you are on the latest it could also be causing you issues. A number of people (me included) saw reduced stability and performance. This is the best BIOS for me, and it is available for the Dark Hero as well. If you are on a newer BIOS you will need to flash using the renamed file and do the BIOS recovery with the button on the back of the I/O or the motherboard firmware will tell you it is too old.

I still don't understand if there's literally several different models with several different antennas or just 2 models and 2 antennas. For sure M14x uses a different antenna. Then there's the SIL-SK63100 vs SK9210-HS models. M14x for sure uses SK9210-HS model but I am not sure what m18xR1, m17xr3, aw17, aw18, m18xr2 use. If they all use the same SIL-SK63100 model then what about antennas? i found a m17xr4 antenna but no idea if it's the same for m17xr3. I also ordered the vizio receiver/transmitter pack on eBay but now need to figure out the DMC port cards. the part numbers I have for m17xr3 are different from the ones for the other models I found online but some listings show aw14/17/18/m18x/m17x all together

Sounds like a potential imc dud albeit you can't rule out the MB either.... I would snag another to compare it against for chip to chip check and to check the MB. Ditto on my first 9800X3D that couldn't do anything past 2000 fclk and 5600 on memory stable. I returned that and my next one is my current one. 2200 fclk and 6400 along with 8200. I haven't really pushed it past that though in light of the newer 9200 sticks. Might need to revisit that.

The first 9950X that I owned maxed out at 2175 FCLK and the 9950X3D that I returned for a refund (a horrible silicon sample) had very high voltage needs, a weak IMC and it would not boot with FCLK at 2175.

Okay! I will try that. Let me check the memory as well.

Just for Giggles, check the SPD tab in CPU-Z and confirm it shows "1" for Ranks. I have a V-COLOR 6000 C26 32GB kit that is dual rank and it will not boot at 8000. (You can also see memory chips on both sides of the PCB.) Dual Rank DDR5 sucks at overclocking. I never would have wasted money on this crappy V-COLOR memory kit if I had known it was dual rank. The voltages you are testing with are too low for 8000 and won't work. Also, you're going to need about 1.600V for VDD and at least 1.550V for VDDQ. Set them both at 1.600V to start and if that works you can try lowering VDDQ. (MSI and Gigabyte BIOS makes them the same value by default and you have to manually change them to different values, so you could leave them both at 1.600 with no problem.) Leave VDDIO on Auto. 1.400V is way too low for 8000. Auto should take it to roughly 1.475V.

I don’t think 2200fclk works. But I haven’t tried really messing with it much either. I do see 2,167 fclk works at least. I feel like I really suck at messing with this thing lol. I saw DDR5 7600c34 posted up and works. But couldn’t get anymore. Need to loosen timing or add more VDD/VDDQ.

The difference between 6000 and 8000 in real world applications and games has been shown on average to be much of nothing due to the memory architecture of AM5, but with that being said it is better to run 8000 if you're able to because at worse, with tight timings, it basically equals 6000 tight but in pockets the extra bandwidth can come into play. 6000 tight if your program really happens to be latency sensitive but even something like WOW which is traditionally known to be latency sensitive on Intel literally ran the same (or close to it) 6000 vs 8000 on AM5. If I couldn't hit at least 8000, I would go back to 2133/6400 or even 2000/6000 but that's personal preference. Did you test your fclk yet to see where it posts up to at least? You posted 7200, are you just scaling up to see how high you can post at this point before running some stability tests later? I've had that problem before where an aggressive EXPO/XMP timing was causing no post. At that point, even scaling the frequency down to Jedec but still retaining the stock EXPO/XMP speeds would fail to post. Usually at that point (pro tip) use Asus tweaked/optimized timings. More times than not it will adjust a bad timing into a proper range then compare EXPO/XMP timings vs Asus tweaked timings to pinpoint the problem(s). You can also go old school JEDEC, set SOC/VDDIO close to max and scale up from there unless you had problems booting JEDEC too?

I cannot get any Gear 2 memory speeds beyond 6000 to run at all, just fails to post. What am I doing wrong? I have set these settings: Asynchronous mode fclk 2000 DDR5 6200/6400/6600/6800/7200/8000 etc. (I tried all these speeds slowly working down) bclk 1: 100.00Mhz bclk 2: Auto uclk Div1 mode=MEMCLK/2 loosest timings imaginable. I cannot get a post. CPU SOC Voltage: 1.200-1.260v tried these ranges. CPU VDDIO/IMC voltage 1.300-1.400v tried these ranges. @Mr. Fox EDIT: I got it!!! I just posted DDR5 7,000. Will slowly work up with some loose timings, then try to tighten. 2nd EDIT: I am having a hard time posting past 7,000 3rd EDIT: I GOT 7400c34 To post and train. 4th EDIT: I got 7600 posted. Still slowly working up in frequency.

does this firmware is compatible with p775 and p870?, where did you get this firmware?? thanks

this firmware seems old, the bin file is from 2016??? does this firmware is compatible with p775 and p870?, where did you get this firmware?? thanks

If you are using the latest BIOS you might want to test something older. I think the version numberings are the same on the Apex and Hero. 9961 is one of the best for memory and CPU overclocking. Some of the latest with newest AGESA are crappy and hinder CPU performance. (Edit: Not sure if older BIOS is compatible with 9950X3D2.) 6000 and 6400 being the "sweet spot" for AMD is a hold-over myth from the days that Ryzen motherboards couldn't handle 8000. (They made up that excuse rather than admit that memory overclocking sucked.) For the best gaming experience you should be targeting 8000 with tight timings and latency below 60ns. It doesn't matter a ton with X3D but the higher bandwidth does help with the "AM-Dip" that Jufus the Dufus talks about. Turn off GDM and set Bank Refresh mode to "Normal" (not mixed). Feel free to give these Dynamic OC Switcher and 8200 memory tuned settings a try and see if they will work for your CPU. Compare my V/F curve values (not necessarily the SP rating) to your CPU to see if the voltage needs are close to the same. ZenTimings shows all of the values that matter. Leave the ODTs on Auto. ASUS does a good job of setting correct resistance based on the detected memory modules. Should not need to mess with ODTs unless they are modules ASUS hasn't optimized for in their BIOS tweaks.

I have the SIL-SK63100. Waiting for the XWH200 to come and I'll test

Ultimate shootout with bonus crapping on Jufus's testing methodology (and others): 4k gaming really shows any of the CPUs finely tuned are on average close to each other capping out even a 5090 and the 10 game average when tuned it is a wash overall except for those rare titles that love X3D enough to make a meaningful difference even at 4k. His results are basically in line with my testing even harking back to 7800X3D vs 13900KS and on but as always YMMV. I would say 1080p is a portend of future 4k potential removing the GPU as a potential bottleneck with more powerful GPUs coming down the pipeline but the problem is X3D cache saturation diminishes as resolution lowers so you can't just predict future gains using a more powerful GPU at higher resolutions (thus lowering or removing the GPU as a bottleneck) using 1080p straight forward... The overall king is now the 9950X3D2 taking into consideration everything. At 4k, I found it interesting the extra X3D on the other CCD actually helps level out some of the saturation deficiencies you can experience at such high resolutions vs the 9850X3D (further adding evidence to X3D saturation issues at higher resolutions). It's a pricey thang though..... ...either way bring on the bLLC! 270k is an absolute banger of a CPU and with the drastic cuts to MB pricing the real challenge is tracking down a set of decently priced 8000+ sticks either as sold or a 6000+ kit and OC'ing it. ------------------------------- Shockingly, those same two $5300 Gigabyte 5090 Infinity GPUs are still in stock at our local Microcenter.... As a matter of fact, they're still in stock at all 10 Microcenters within a 150 mile radius too.... 🤣

I was doing some research, it seems the SK9210-HS model is specific to the OG M14x. The SIL-SK63100 seems to be newer and has fcc listing for AW14/17/18 & M14x/M17x/M18x series. It's possible you have the older card?

the thing is, the VM dont make a passthrough of the audio codec, it gives me a different HWID, how its supposed to be tested?

I’ll mess with it some more. When I enabled high priority it does hit 46K at least. Not sure if that helps, as I’m just using a stock retail Win11 OS. Anyways, I’m messing with ram tuning right now. I just let the chip run stock for the most part trying to memorize and learn AMD things. Good news is my ram booted right up at 6000 CL26-36-36-36-96@1.435V. My motherboard seems to be responding a little bit better as time has gone on. It might be okay after all. I see training and posting with high tREFI is much easier with more VDD/VDDQ voltage. So, like 6000c30 with 65K tREFI won’t post with 1.400v VDD/VDDQ. But it will post with 1.435v VDD/VDDQ. I know how DDR5 was with Intel, and it was heavily dependent on your IMC quality. Like one CPU may do 6000c30@1.35v and another CPU wants 6000c30@1.400v. That’s what I learned with Intel anyways, the CPU IMC quality determines how much voltage your DDR5 rams would need. This made it incredibly difficult to bin ram sticks in my opinion. Because an amazing IMC would make average DDR5 look like super sticks or something.

I know it's not "in fasion" for AM5, but I would test a max static OC just for reference/capability and then carve out a PBO OC against it for comparison. I've done this with every AM4/AM5 CPU I've owned. I did it on my 5800x platform I ran and all subsequent 7800X3D/7950X3D/9800X3D platforms. And as @Mr. Fox referenced, this will definitely blast your temps and give you an "Intel like" experience OC'ing. SP118 is a solid average or slightly above average chip but check the IMC and see if it can do 2133/6400 at least and hopefully 2200/6400 on the G2 level then push for 8000+ and see what it can do. I've done that before. Bought something then sat on it for a week or so getting over buyers remorse and finally cracking it open. I JUST did that with my replacement iPad M5 13 2TB Wifi+Cell Nano Texture I picked up open box saving ~$1k. I left it on the table all week while I limped along on my slowly dying Ipad 12.9 M1 128GB peasant edition. 🤣 I told ya the switch from that capable but old Intel HEDT to X3D with that 5090 was going to change your life. 🤣 Well, maybe not that extreme, but you could tune up another 14900, 270k or X3D and any of them would best your soon to be old rig. The real sweet sauce is when you run across select titles that absolutely love that X3D cache and really sing.

You cant. Prema went into obscurity long ago from the forums. What gpu do you have, and why do you need an unlocked bios for?
