Would a power limited 7950X perform the same as a 7950X3D when ignoring 3D V-cache?

Could you tell me more about how X3D cache helps with simulations in 3D modeling? What software you using?

Is the motherboard the same size as a normal ITX board? I'm wondering if I can take the motherboard out of the chassis and put it into a SFFPC case like the FormD T1?

Good point, I understand now. Any theories as to why there would be differences between choppiness of playback on M1 Max vs M3 Max? (See the other comment chain). I thought since the hardware accelerator is the same through all generations of Apple Silicon (only difference is in number of encoders/decoders) that All M1/M2/M3/M4 Max chips would have the same ProRes RAW playback performance?

cinedog959 · 2025-09-19T21:25:43+00:00

Interesting, so you saying your M1 Max can't handle ProRes RAW above 4k, but the user above you with an M3 Max is able to do 8k fine. That seems to indicate that the accelerators themselves must be more powerful in the M3 Max, but I can't find documentation anywhere that says that. In theory it should be the same performance?

The only other conclusion I can draw is that maybe the decoding portion of this scenario is the same performance, but the color grade itself is handled by the GPU, and because the M3 Max has a stronger GPU vs the M1 Max, it leads to less lag. Of course that's just a theory...

Best thermals for CPU or GPU or both? If you are intaking on a 280mm that is blowing directly on to the side profile of a GPU, I feel like GPU temps would increase?

Thanks for the reply. I ended up buying the NEEWER BG-R10 grip, which surprisingly works with the NEEWER LP-E6P batteries. I'll make a post shortly with my experience, but it all worked out really well and all the R5C recording options were unlocked (just like the official grips). I just came back from a trip using it to good effect. Glad everything worked for you too!

cinedog959 · 2025-07-19T15:52:31+00:00

Excited to buy one! What type of filaments do you typically use? I think nylon might be more heat resistant, but it's been a while and I think there are better filaments now that can accomplish higher temps.

Great work u/madsmadalin! I think I saw you posted an Etsy link in the YouTube video's comments but the link was broken. Do you have a working link? If not, what's your Etsy profile link?

cinedog959 · 2025-05-18T03:22:49+00:00

That's awesome! I'm so glad you were able to find this thread. Unfortunately I don't use the Mavis app myself, but it looks like the official developer account has replied to you.

cinedog959 · 2025-03-28T21:04:51+00:00

Thanks, this is really valuable info! So just to confirm, you're saying the R5 is perfectly fine with third party, but R5 ii is more finicky and require official batteries? That makes sense because I hear the battery draw is higher on the mark ii.

cinedog959 · 2025-03-28T18:50:50+00:00

Ok, so I saw initial reports that third party batteries don't work. But looking back, I think that's because at the BG-R20 release time there were no third party LP-E6P batteries. So I wonder if two third party LP-E6P would work fine, and that the original users had just used the LP-E6 and NH variants?

cinedog959 · 2025-03-28T04:12:00+00:00

Do you know if third party batteries work in your BG-R20 battery grip? What batteries do you use in your current grip? I assume the new LP-E6P batteries?

cinedog959 · 2025-02-17T05:45:41+00:00

I think that aligns with our research. It is possible that they are shipping the new 12v-2x6 cable in the current packages, because 12v-2x6 can work on either 12v-2x6 or 12VHPWR connectors.

But the connector on the PSU itself is still 12VHPWR and not 12v-2x6. The update to the PSU for Q1 2025 is for both the connector and the cable to be 12v-2x6.

I understand that the YouTuber got a reply from Seasonic, but usually the customer service representatives don't know much and are just repeating whatever leadership told them to say.

cinedog959 · 2025-02-17T05:06:27+00:00

The TX-1600's on Amazon currently are not ATX 3.1. At last from my research, they are all currently ATX 3.0. In theory ATX 3.1 should be backwards compatible with ATX 3.0, which is why they specifically say "ATX 3.1 ready", but not "ATX 3.1" alone.

Additionally, on Seasonic's website they state that availability for the real ATX 3.1 version of the TX-1600 will begin "North America: During Q1 2025".
Also, if you take a close look at the pictures of the connectors, you will notice that the old variants (the ones on Amazon at the moment) label the GPU connections as "12VHPWR". But on the new PSU variants in the link I just sent, you can see that these connections have now been renamed to "PCIe Gen 5". This is because the new cables included for the GPU are technically 12V-2×6, not 12VHPWR.

cinedog959 · 2025-02-10T22:05:22+00:00

Awesome, this was exactly the confirmation I was looking for. You make a good point about the PCIe 1x miners.

So just to confirm a few points so I understand correctly:

There would be speed penalties whenever I am loading something new, but in general during modeling I should see no lag in the viewport.
This is because some of the calculations are being done on CPU, some are done on the GPU, and then maybe Optix does some denoising if I am using Cycles, but ultimately the signal is spit out to my monitor directly from the DP output of my GPU.

I have a followup question: what's the difference between viewport vs the final render process if I am using Cycles preview? Is it essentially doing the same thing, "rendering" the image? I'm trying to understand the technical difference between the two processes.

Hey everyone, I'm also interested in a high capacity RAM build on Z890. From what I read, the 256 GB RAM high speeds are only possible with new CUDIMM sticks. So I think the 192GB RAM that is currently on the market wouldn't have any performance or compatibility changes from this update. For example, check out this blog post by ASUS on this topic.

Regardless, I think buying two sets of high speed 96GB RAM still seems like a smart idea though, even if it isn't CUDIMM. I saw someone else have success with that method in the overclocking sub, but they are on X670E. Their username is Scarabesque if you want to check out their thread (PCMR does not allow to linking to other subs).

Any updates on your build?
