Red PCB HD 7990, nice. Shame the sticker was removed. Got BIOS or board dates off it yet?

 

[mouacyk]

All of Ampere and RDNA2 can be added to the list...

Complete right, card is nearly dead, only one LED lights up when plugged in, even as second card no access to BIOS.

I saw the ES sticker bevor buying the card. Card should have a 2012 BIOS older even first release Bios of similar Firepro S10000. Asic typ is pre Malta and missing in the TPU database.

Since we're showing off AMD samples again, here's one I got a few days ago.

Radeon R9 290X Engineering Sample



Card boots up fine and drivers auto detect it. The primary BIOS it's set to load is a fairly early UEFI from June 27th, 2013. About four months from launch. There is an even earlier BIOS, only 64K in size, from May 2013 that contains only the most basic display table requirements for Windows to recognize it as an output device. It targets a more aggressive 950MHz core clock closer to the final design, and carries the previously unseen and thought to be entirely unused 67B8 device ID. This firmware was validated for the first time here on TPU and a database entry now exists for this card here. The card features the flat black plastic shroud that's fairly common for early to mid development AMD samples in the last ten years, with only a couple hints toward what the final shroud design would look like. The PCB featured an array of physical switches for various points around the power delivery; almost all have been removed. One striking peculiarity of the PCB design is the physical CrossfireX fingers at the top. AMD did away with CrossfireX bridges with the R9 290 and R9 290X, opting for PCI-E communication with xDMA. Without another early board to test with I can't do much to determine if those connectors are functional for anything, whether it be CrossfireX or simply signal analyzing for debugging card communications. Either way it's neat to see that the familiar CrossfireX bridge wasn't officially dead with Hawaii, and the physical change came later in development.

Spotted some missing caps. Can't quite make out what the far right one is
Some more ripped pads across the board too

Correct. You missed some, still.

Anything with pads gone was removed by an engineer. The card is still functional, with most of the missing components being simple filter caps or test switches not necessary for full operation.

We have had those pics for months but better quality xD

I think I have a Radeon 2600 XT in the attic. I'm not sure if it would be considered rare, but it's one of the only GPUs I've even seen to use GDDR4 instead of 3 or 5.

Nah they made a bunch. Wasn't a terrible budget card in its day.

Other cards with GDDR4: X1950 XTX, X1950 Crossfire, HD 2900 XT, HD 3870, FirePro V8650, V8600, V7700, V5600, and of course your 2600 XT.

I think a current gen GPU would be a candidate for this thread

OH I love that 5970 Black Edition! Such a nice collection!
So hard to get high quality PCB pictures of it

here ya go

Sorry no 3070, they arent worth the extra $100 over a 3060ti, price/performance is not in line

You get a pass for being first to do the joke in this thread.

Ok, that's enough with that joke. Funny as it is, let's keep it real.

Hello everyone,

I have a few more items to share in the hopes of motivating myself to get around to thermal testing the next round of coolers that I discussed previously.

First off I acquired an engineering sample HD3870 X2 to go with the non-qualification sample HD3870 that I posted earlier.

I also picked up a 7800 GTX 512MB which was a very short lived flagship that I've been after for awhile. Boy does it need a good dusting.

Lastly I acquired two coolers that I consider groundbreaking in the history of GPU cooling. I plan to run some tests with both, a stock 3870, and the vapor chamber 3870 that I posted earlier but man its going to be a lot of work especially with different fan configurations.

This are history pieces (at least for me, 3870 was the 1st GPU I bought )
