Who got a 7900XTX or 7900XT?

Make sure to stress test it and check the hotspot temps. Also, I think the XTX needs to be installed in a certain way for the vapor chamber to work correctly (don't remember the details).

I have it installed standard in a Phanteks full tower. My SOP for may years when using AMD GPUs is to under-volt them after initial testing. Stable so far at 95% voltage and 95% power limit. Hotspot is 81c after TS xtreme run with a score of good. Defaults with max 115% power limit scored excellent but hotspot was 93c. That's a big temp swing for performance I don't even need. Especially for a single run. I'll get it dialed in so hotspot never sees 85c while doing long gaming sessions during the dog days of summer.

For what I paid it's a bang for buck champ. The only thing that could have made it even better is a multi bios switch.

OK, fair enough. But you do have some barely usable backup PC, right? Coz not having one is going to make you absolutely miserable if your primary system suddenly decides to give up the ghost.

I'm more concerned with breaking something when building the new rig. This old hardware is still rock solid. For now.

I'm always scared too when touching my system. That's a very valid fear.

I think you are speaking about people side mounting the initial batches of the XTX which seemed to help with hotspot temps.

In particular it was certain reference cards only. There were batches where the vapor chamber on the reference cooler wasn't working right.

ASRock first to launch Radeon RX 7900 XT(X) GPU with blower-fan and 12V-2x6 power connector - VideoCardz.com

First Radeon RX 7900 with 12V-2×6 connector announced ASRock has a graphics card for AI workstations. ASRock has announced new Radeon RX 7900 XTX WS and RX 7900 XT WS graphics cards, designed as dual-slot workstation GPUs powered by RDNA3 architecture. These cards are aimed at workstations...

Now this is exciting. Hope RDNA4 also has these blower cards. I like slim cards.

In a way I am horrified. I certainly hope they stick with 8 pin options in the future, and don't start forcing new melty/flimsy connectors on us.

I"m one of those guys who prefer the blower style cooling solution.

Seconded. I realize the comment doesn't add much but it has to be said. 12VHPWR connectors, in their latest incarnation, might be okay-ish for midrange and lower cards, but they do not have enough power headroom to handle high-end cards.

But melty connectors mean RMA rejection, and a excuse to sell another one. (sarcasm)

But i think the gpu vendors knew about this and pushed for it.

 

[Shmee]

Yeah, hopefully they don't go that route. If they do, well, I don't mean to get political, but hopefully they all get investigated by the FTC or whoever and things get fixed.

I've never understood the need for the 8pin connector. It just adds 2 more ground (black) wires and that doesn't enable the power (yellow) wires the ability to handle more amperage.
If they had made the power wires a larger gauge at the same time, it would make sense, but they didn't.
So since the 3 power wires are the same size as the ground wires they can't handle any more current than a 6pin connector could.

I was curious so I looked it up a bit. Here's the TL;DR

• officially the 6-pin connector has only 2 guaranteed +12V pins, the third one can be +12V or Not Connected. Also, one of the pins represented as ground in many online schematics is actually a sense pin.
• the 8-pin connector guarantees 3x +12V pins and adds 1x sense pin and 1x ground pin
• in real world PSUs can offer +12V on the third pin of the 6-pin connector, all modern PSUs offer 8-pin connectors that can be used for 6-pin connections instead.

So what the 8-pin connector does is to guarantee the third +12V pin and also introduce extra sensing so that components know what type of connectors are completing the circuit.

Here is a break through on my Nitro+ stock OC VBIOS, Steel Nomad. Seems sensitive to memory.

 

[BTRY B 529th FA BN]

That's pretty good Mem speed for tight timings! VN

 

[Shmee]

What did you settle on for your OC settings for your card? Also are you under water or using the Nitro+ cooler?

I'm under custom water, testing the following settings on D4 atm. Variation of the profile for that SN run.

I have someone that wanted my reference model so I swapped it out for the XFX Magnetic Air version.

Was abit more work than just the GPU swap since I was missing a 3x8pin required for the new gpu.

Previous GPU was only 2x8pin and I didn't have a 3rd cable so I actually ordered one from amazon the day before since i'm using a cable mod kit. So while I had to route that extra cable through I figured I would clean and recheck some out of other cables. Its easy to keep the clutter to a minimum in these fractal cases.

With my reference card I was looking at about 345-350 watts usage on this card with the default bios were doing about 390 watts.

I have no experience with Cable Mods but they do a great job with aesthetics!

Good lookin rig, cheers! :beer:

The https://cablemod.com/ kits are easy you just need to find cables that are compatible with your PSU. Aesthetics wise much cleaner better looking than the stock cables that came with my PSU.

That's the thing that scared me away was buying the right cabes. Plus my old cases just can't be enhanced anymore.. still using a Corsair 800D and some ABS Black Pearl that me and a couple other guys on the forum puchased.. i think idontcare was one of them,, member that guy? wow long time ago

Compatibility – CableMod

The list on the site is easy. I already found cables for you PSU

And I remember Idon'tcare haven't seem him in ages.
