Question 192 or 256bit??

[Yannis.]

Hello everyone. I will try briefly to tell you what happened.

One week ago I bought this Asus Tuf Gaming RX6700 XT 12GB card. Ref no 90YV0G80-M0NA00 . As you could see in the company's site the item is announced with two memory interface values. One week now after talking with both Asus USA and here in Greece they do not claim any mistaken discription. On the contrary, they insist that the card is performing both interfaces by moving the switch to the "Proffesional Mode" position.

Please someone, if you or someone you know have this card on hand or system take some time and make this test. Does this card indeed perform both values?? Because my card doesn't and they say it is a deffective card. I don't know what to do. I just like to have in my hands what I pay for....

I hope you understand. Thank you for your time.


PS: X570 tuf MoBo-R3600X-32GB crucial on 3600MHz.

The switch is for the Dual bios. I don't know if that enables the 256bit bus or not. You'll most likely need to change it with the PC off (not sleep or hybrid sleep (win8, 10, 11))

Thanks for your reply my friend.
Let me say that I used both sides of the switch, after a restart , more than once , and even along with the store's technical team I bought it from. We were struggling for more than two hours changing profiles and modes and restarting and testing.
My only hope is for someone to know exactly about this issue, or someone who owns this card to run the tests himself.....

If you can get it to boot into Windows just load up GPU-Z. That will tell you whether you are operating at a 192bit or 256bit.
My guess is that you choose between slower memory interface and more memory (12GBs and 192bit) vs. faster memory interface but less memory (8GBs and 256bit).

Already did that from the beginning my friend. GPU-Z said 192. After that I contacted Asus and they say no, card can play 256bit. And the store I bought is transferring one last piece from other town to test this one too in case first is broken somehow and mailed Asus also for an official update.
But...I doubt that... 🤔

It did seem very weird to have that kind of a switch.
I guess it's technically possibly (with an alternate GPU core from the standard 6700XT) but it would take a lot more engineering for not much/no gain.

Problem is, I didn't ask for it, they give it I take it. That's what the official specs are from Asus. And I paid for that. And I claim it. So they should prove they are right and not misleading..

Is the issue that it's 192bit even with the switch in both positions?
If yes, this sounds like a straight error in the specs listing. I bet that it's just a BIOS switch for setting a more aggresive vBIOS OC and nothing more than that.

Best they'll probably offer is a full refund. If the performance is good compared to other 6700 XTs I would just keep it.

I agree with you generally but, you know what? Ten days ago I knew nothing of all these mambo-jumbo about bits and deeper details. It just happens to be a mechanic in my Service and I like robust constructions and technical details. But do you realize how many people in the world bought this one just for this ''256'' written even by mistake?
If they offer me a fair discount, I would keep it too. I have nothing against lesser, and I respect and embrace anything or anyone who admits his limits. But I just demand what I was promised.

I think someone needs to call ASUS out on this.

Officially AMD says the RX 6700 XT has a 192-bit bus. And the way memory works on video cards is that every memory chip has a dedicated 32-bit bus. 192 divided by 32 gives us 6, which makes sense with 12GB of VRAM (2GB chips are common now and days). If ASUS really has a 256-bit bus on the RX 6700 XT, then it should come with either 8 or 16 GB of VRAM. Otherwise it'd have to come with 4x1GB and 4x2GB chips, which doesn't make sense to me. The reason why video cards do this setup is so data can be striped across multiple chips. Having mismatched sizes means you can only do striping on part of the entire pool, which reduces memory performance. And also, since nobody else appears to claim to have a 256-bit bus, either ASUS shipped this thing with special drivers or the drivers are going to have a fun time trying to access memory in a way that the card won't like.

So I think there's nothing wrong with the card. ASUS's marketing just screwed up.

Ι really appreciate the time you took to write these essential details to prove that I have nothing to wait indeed...
Who do you think should call them out and how? You don't really have to answer...
I just am really pissed off with the misleading.

As I said before, best you'll get is a full refund, unfortunately. They can't produce something that doesn't exist.
