Okay, I've been slacking a little, since I recapped and tested the second 8600 GT video card literally next day after I made my last post on 10/15. But I promise I will get them in soon (I'll try by the end of the week).

This topic inspired me, thanks!
Glad to hear that!
GeForce 8500 is also a decent video card for H.264 acceleration and YouTube. But for games, it is closer in performance to the 8400. At least it seemed that way to me from my brief tests this summer when I fixed a PC for my cousins.

Yes, the Xbox 360s have many faults, some of them not repairable. I used to work in a PC repair shop that did mostly Xbox 360s and PS3, so that's why I have so many of the Xbox 360 heatsinks.

Cool! If the price is right, get it and give it a try.

Unfortunately, I understood from the seller that XFX 8600 card cannot boot into Windows, shows some artifacts then move quickly in black screen.
I noticed a slight discoloration on the back in the gpu zone.
Maybe it can be fixed? Be required a reballing/reflow? Of course, I can not do
a reballing .

Looks like your 8600 GT above has been recapped already (though I still see one Sacon FZ at the corner).

If the seller says it has artifacts, I do NOT recommend you buy it, unless it's extremely cheap and the parts you get out of it are worth more to you. I say this, because once a GeForce 7/8 series card artifacts, it's usually done . There is a very small chance that a reflow may bring it back, but don't count on it. And reballing, in my opinion, is a no-no on these cards, particularly if you use a suction/vacuum pen to pull the GPU. What I have noticed with GF 7 and 8 cards is that if they are hot and you insert any kind of pressure on the GPU die, it will screw up the chip even more (I had a GeForce 7900 GS go completely short-circuit on all power rails).

So, I'm sorry to be the bearer of bad news, but I think that GeForce 8600 GT is destined for the bin. ... or parts pile.

Also, the discoloration on the back could mean that either the card has ran way too hot at some point or that someone has already tried reflowing it.

Good points, and I was afraid of the same things you have said.
Thanks.

Thanks. I've actually improved on the mod even further. Just needs a few final touches before I show pictures.

Also have to post results of that second 8600 GT I got.

And if anyone in the USA is interested in getting one of these cards, here's an auction for a 512 MB version of this card going on eBay right now:

Two of the FZ caps haven't even popped yet, so there is a very good chance of reviving this video card with a recap.

Great, mod, looks very reliable and long lasting.
Those tingtening bolts look like they were instaled at the factory.

Well, I still think it needs more work, but it's too cold in the garage for any work at this time of the year, so who knows when I will get around to doing it.

Time for an update again.

Running it "open" on the heatsink is okay for the low temperatures in my room now. But I think summer could be problematic, so this needs more testing.
So I did that (added a fan shroud, that is) and got some pretty decent temperatures again: about 56-57C absolute max under load. And this was in a room temperature of 84-85F / 29C. Here are the pictures of the further-modded heatsink:



Also, a temperature curve with an X-axis showing about 13 minutes worth of temperature logging (I actually had the card running for much longer, though, so that it comes up to normal running ambient temperature before doing my testing):

Worth mentioning is that this is an old graph without the fan shroud. With it, I got pretty much the same temperature curve, but with the load temperature slightly lower - mostly sitting at 55C and only occasionally peaking to 56-57C. This is with the GPU completely maxxed out under load.

That said, I think the next heatsink revision will be to flip the GPU heatsink 90C so that the airflow is across the video card instead of taking air from near the PCI/PCI-E slots and blowing it towards the side of the case. But most importantly, I think I need to change that 50 mm fan for something else. Sure it looks nice with that fan shroud on top of it, but it is way TOO LOUD. I also can't turn down its speed, because this video card offers no control of the fan... and even if it did, then I would likely have higher temperatures, which is what I don't want either.

I think the solution would be to find a 60-70 mm high-pressure fan and run it at a lower speed. Makes me wish I had saved some of the recycled iMacs at work - those have pretty decent high-pressure squirrel-cage fans in them. I guess I will play with it more again. Looks like Drack is right - this is going to be one of those projects that never seems to end.

Well... turns out IT WAS my PCI-E slot that likely caused the "dead video card" symptoms I mentioned on the first page. After testing various video cards for a year now, I've found that sometimes I have to take them out of the slot and re-seat them a few times before the motherboard recognizes them. So I guess it is no longer safe to say that the PCI-E slot on my 939Dual-SATA2 is fine. But most of the time, it still works, so I am not going to replace that motherboard just yet. And at least I know now, that when the video card appears dead, I re-seat it several times, and that usually fixes it. If not, I test with a known-good video card and then try again. If that doesn't work, I try the video card under test in a different computer (so that's why it's always a good idea to keep a few spare PCs laying about ).

And a thread for that is coming up in just a little bit.
