Flashing my 6600 XT to 6650 XT

[3x0]

The only reason to crossflash it IMO is to have higher clocks out-of-the-box and not having to manually enter the OC settings in the driver, nothing wrong with that.

 

[eidairaman1]

No, he's not just overclocking the card. Overclocking is just going into whatever tools AMD provides to boost clock speeds/voltages to 6650 values. This guy wants to reidentify the card to make it look like it's something else. I'm not a fan of this slippery slope situation. A 6650 XT has a quality that the 6600 simply does not, and people who think it is okay to rebrand a card simply because the card can do it don't understand the reason why a 6600 XT is not a 6650 XT. It's not just the clock speeds and power, it's the longevity of the card as well.

Wanna know what really trashes a card, mining

I see way too many rx580 and 2048SP 580s/570s roll through here that were damaged by it, that once the card is restored by bios flash they can't function properly.

It would be just like me taking a Sapphire R9 390 or X Nitro Bios, Modding it to detect my 4G of ram and increase its clock speed, possibly voltages and timings and dumping it on my card so it runs faster

Really no different than the official bios launch to make 12Gbps RX5600XTs into 14Gbps units

Stay away from personal insults folks. Edits and deletions have been made.

You can overclock 16 Gbps memory to do 18 Gbps, but its factory rating stays the same, so does its etched model number.

You can also overclock the genuine 18 Gbps memory on a 6650XT to 19.5Gbps which is additional performance the 6600XT's 16 Gbps will likely never achieve.

 

[whereismymind]

It's not a 6650Xt, get a grip and reflash with stock bios, stop conning people, asshole.

Not a con artist. I'm not selling my GPU.

Can I rename my card to 6666XT since it overclocks past the 6650XT?

I don't see anything wrong with crossflashing it to a 6650XT, unless one tries to sell it for more by faking it as a 6650XT. The OP didn't say that is his intention.

The price difference on ebay between an 6600XT and 6650XT is pretty tiny anyway. In the grand scheme of mastermind crimes for profit, I'm sure this is far more manual labour than the actual boost to resale value so I doubt resale value is even relevant as an option here.

I have (or had) 6600, 6700, 6700XT, 6800XT cards at home and on every single one of them, they were stable at the maximum VRAM overclock exposed by the driver. Flashing to a 6650XT will at least give @whereismymind more headroom on the VRAM slider. Not that I think he'll get much further than 2300MHz. That was where two of my own 16 Gbps cards ran out of headroom on the VRAM.

Edit:
Oh, it's worth noting that you can crank the VRAM insanely further than the stability limit of the VRAM before it crashes or resets the driver, but GDDR6 has error correction and an unstable overclock can give you higher reported VRAM clocks but in reality your performance starts to decrease quite significantly. For my 6700 the card didn't crash until 2325MHz but benchmark runs to validate the OC proved that 2280MHz was the absolute limit of the RAM before errors started to hamper performance.

if i cant get the card to run like a 6650 XT, I won't flash it as a 6650 XT. first I'll try and make sure my GPU supports the OC to make it run the same as one, and then I'll flash it. I just want my graphics card to be better, while making it aesthetically more pleasing on task manager and etc. the reason why im doing this is NOT TO SELL IT, that's a promise. i just got my card recently. stop insulting me for just wanting to make my card run better and making it appear like a higher binned model. I do not resell my GPUs.

Anyway, the 18 Gbps and 16 Gbps debate won't matter to me if I can get the 16 Gbps chips to run the same as the 18 Gbps ones. (big stretch, i understand.) If it's not possible, forget the flash.

Well we are here so

 

[Solaris17]

So this guy is just OCing the card, the 6650XT is a Refined 6600XT, Just like the 9600XT is a refined 9600 Pro or 9800 XT over a 9800 Pro...

Not to mention the cross flashing you could do for RX470/80's into the 570/80s. or the x8xx cards before that? Or ATI/AMD into pro cards, or nvidia into quadros.

Cross flashing is a tale as old as time and this forum used to be a hub for it. Let the man flash his bios.

 

[AlienIsGOD]

if not contributing to the thread id suggest clamming up, this forum is known well for flashing cards. I have dual bios on my rx 5700 that has 1 flashed to a 5700xt thnx to this https://www.techpowerup.com/review/flashing-amd-radeon-rx-5700-with-xt-bios-performance-guide/ and @eidairaman1 help. As was stated before, not one intention or comment from OP was made about selling the card. there's more than one reason to flash a card in the same series and the 5700 was a very popular one to flash to XT speeds and power limits.

OP even if you were to sell it all you would have to do is list it as a 6600XT flashed to a 6650XT, a savvy marketplace or Craigslist buyer would know exactly what that entails and not be caught off guard

Oh man I remember helping you with that. I will say amdvbflash has gotten better and learned that in some instances 2.93 that is here doesnt work but igors lab version of 2.93 does, and the command syntax has changed in the latest version, and i believe is the same in 3.31.

Oh the amount of 580 2048sps ive helped restore or switch to 570s, heck downgraded a 580 to a 480 due to a weird bios glitch...

In that case, what you're asking is pointless. Just set 6650 XT clocks in the driver and call it a day. At least you can easily revert to default if there is a problem later on.

I think you are missing the point, OP would like his card to appear as a 6650 XT. Are there better ways to accomplish the end result? Yes, but that isn't the point of the thread. Kindly let them flash their BIOS in peace

Well, if he doesn't mind introducing a million potential problems, including bricking his card, for nothing, then be my guest.

Why are you so adamant against this? It has 0 to do with you so I I'm not sure why every post you make on this thread is negative

THIS.

Years ago and I mean waaaay back I found reference to this site and used the info to reflash my Sapphire X800 GTO AGP card so it's extra pixel pipes were unlocked.
I wasn't trying to change the card's identity or anything like that, just to enable all that was there if it was available to use in the first place and in my case it worked. Still shows itself as an X800 GTO AGP as it should but also shows itself with 16 instead of 12 pixel pipes, which is nice.

Let the man flash his bios.

I get the concerns some of you have and it may even be warranted but at the same time it's not your card either.
If they want to flash it I don't have a problem with it because it's not my card - End of story with that.

It's only if reselling it this can be a problem - We've all seen fakes out there with guys coming here to get all that fixed as well. It has been pointed out already the OP hasn't said a thing about selling the card but then again they haven't said anything about not selling it either.
Either way it's none of our business unless we are directly involved and I seriously doubt any of us ever will be with this card at least.

So...... let the man flash his card already.

 

[Colddecked]

Understand this is no different than Flashing a RX 5700 into a RX 5700XT or a RX5600XT 12000MHz Ram into 14000MHz Ram (GDDR6 is octopumped)

Flashing a 5700 with xt bios is basically lifting the power limits doesnt change ram or clock speeds. 5700 and xt use same memory unlike 6600xt and 6650xt. The ram timing is the biggest thing you have no idea if the 6600s can run 6650s memory timings. Imo its better to use mpt or manually oc it.

And selling as a 6650xt is just plain wrong I dont understand how anyone can condone that

Because OP is asking us to help with something that has zero benefit, but comes with certain dangers. I feel it is my duty to warn them of said dangers and make sure they're aware of the imbalance in the cost vs benefit equation in said procedure.

You don't just go to your doctor asking for a brain surgery and expect to undergo the operation without understanding the potential complications first. And then, if we're talking about a real doctor, they won't perform anything without doing a thorough examination on you and making sure it's necessary.

Going on and on like you are some type of martyr isn't helping lol. You act like flashing a card is immoral and absolutely wrong. did you do this when all the ppl here were flashing 5700 non xts to XT bioses? No you didn't. You have made your point and currently you are beating a dead horse and coming off looking very uninformed about the whole flashing situation. Maybe read up a lil before acting the protector of unlflashed cards

Flashing isnt immoral its your card you do what you want with it. But selling the card as a 6650xt is immoral and I think is what most people in this thread have an issue with.

Then you all lack reading skills tbh. He has stated that he doesn't want to sell the card. Y'all refuse to see that post and act like it's on marketplace right now. It's several posts up in bold from OP even. So idk why several ppl are going on about selling the card as a 6650xt. It wasn't stated ever he was doing that and if he were to sell it I have given him sound advice for 2nd hand site selling with. A disclaimer about it being flashed. Reading skills go a long way in a tech forum guys

I could have swore op wrote something about being able to sell it as a 6650xt maybe that post was edited or deleted. Seems weird for people to just start complaining about that if OP himself didnt state that was a possibility. Anyways thanks for the reading skills tip.

It is only most people in the thread if you are only counting the ones raising the concern, No where at any point, until it was called out by some member, did OP ONCE indicate he wanted to do this so he could sell it.

We are done with this line of conversation now.

The posts will stay of course, but I implore everyone to continue talking via PM amongst yourselves regarding your thoughts about cross flashing with like minded people. We are now too far off topic.

If you don't have instructions or contributions to help OP please don't bother.

The only reason to crossflash it IMO is to have higher clocks out-of-the-box and not having to manually enter the OC settings in the driver, nothing wrong with that.

Yes, but you achieve that by dumping your BIOS, editing the frequencies and flashing it back. Not by making your card report itself as a 6650XT in GPU-Z.

 

[ixi]

Waiting to hear from OP if he succeeded in flashing from 6600xt to 6650xt for the science of god
