Hi everyone 
 
 
After quite some stressful moments I was able to get both my Reds up and running again, here some lovely pics I took of the main card the first one I worked on and yeah I did both cards twice because the Internal SLI Ribbon cablees werebeing a bunch of pains in thye rectums xDDDDDDD It is funny now because now I can only LMAO about it HARD lol.
 
So how about a stroll down Memory Lane shall we?
 
This is what you get when you have neatly unscrewed your GTX 295 Dual PCB and cleaned it's GPU's, here a Red Edition which looks identical to the normal GTX 295 Dual PCB:

 
Here a closeup of the main and slave PCB of the main GTX 295 RE:

 
After cleaning the main PCB this was my result, I did the NF200 after I made the shot, not to worry

 
After making this shot I could see this GPU still needed cleaning

 
What I did was also remove the shim of the GPU , that metal thing that sits around them, you can remove these by removing 8 tine screws from it's rear side, keep these in a safe spot please, you don't wanna go shimless right! ieuw
 
Here the slave card all cleaned up

 
As you can see the GPU is a G200-400-B3, kinda odd that GPU-Z sees them as GT200 B1 lol, maybe a mistake in GPU-Z?

Odd hay?
 
Anyhoo on with the cards again
As you also can see here I removed them 8 tiny screws to clean the shim, that metal thing that sits aroudn the GPU, it also had paste and gew on it rofl so did mah fingorzzz xDDD

 
Here a very nice closeup I was able to shoot of them nasty critters every GTX 295 Dual PCB user feared from the Internal SLI Ribbon Cables arrghhhh The memories rofl!

I later figured that these had to be turned around and now they work fine lolz xDDD
 
And here the G200-400-B3's pasted read for HSF montage!

 
Here I carefully placed the big HSF:

 
Also making sure it was placed correctly, due to the first bad rides it gave me, I did learn rofl!

 
These two long black plastic rods are also parts you must not forget to place, you can also fit them once you have partially screwed both PCB halves together, I did it like this and the other way:

Just make sure you never try to over stress force on the PCB's while getting these two in place once both PCB's have been attached partially to each other, this jittering can also loosen them SLI Ribbon Cables! Then your mind will be like Oh nooooeeessss not agaaaiinnsss Arghhhhhhhhh!!!!!!
Brruuuuuds!
 
And here ya go the first card in it's beautiful Ferarri Red coating! Yippiieess Hooraayyss

 
Here from the side view, everything looks nice and clean

 
And here the rear side view :)

 
And after doing the same twice with the secondary GTX 295 RE this was my result!

 
The Quad SLI worked after the second time, the first time I had a red light on the main card and a green on the secondary card but it gave no screen, I placed it along side the main GTX 295 RE after I did that oen for the second time and it only showed 1 GPU, so after this I redid the second card and now I have 4 GPU's again and Quad SLI runs great.
 
The thing is I want to do longer with these GTX 295 RE's just due to their great rarity, so if you really love your hardware this much you'd do this to them , caring for your hardware can save their lives and your wallet!
 
Many thanks for reading and feel free to ask me anything based on GTX 295 Dual PCB Maintenance, I'd love to help!

Could be, or the NF200 SLI-chip is dead.
The GTX295 is a tricky card to dis/reassemble, but as long as you are careful it should be OK!
Try to disassemble your card and see if the internal SLI-brigde is loose.
 
@OT - looks good! The moment you told me both cards were dead really made me feel sad :( Good to know that both of them are all righty ;)

Alright thanks! Mine it shows one core folding and in precision, but the display does not work and of course one core does not work.

your thought ?
 I'm thinking of getting a set of 295 if the price is right(don't play and dx11 games)
 
have you done any benchmarks on it
and have you played sckrim with them? if so, how well dose it play

A single GTX295 play Skyrim pretty well! Two will always do better ;)

Skyrim is Fallout3 in the middle ages as the engine goes it's nothing special imo, just another DX9.0c game, easy for any GTX 295 even in single chip mode it will run just fine.
 
FEAR 3 is by far the best game I ran with Quad SLI without any issues what so ever @ 1920 x 1200 x32 + FXAA & AF x16 @ min max 60fps in DX10 mode and this game is a real blast with Quad SLI mode.

@ EVGA Mods :)
 
Many thanks for giving me a Blue Ribbon for this one, this wasn't an easy task though, it was rather scary but it was very educable
 
@ voodoo do-er
 
No probs, I ran Fallout3 & new vegas on these reds and they tear through those games, only to what is very well known games from Bathesda aka Bugfesta are packed with instability bugs which can cause the game to crash, I have tested it with new gen Radeon & GeForce VA cards, it's mainly the game Skyrim in your case which is being the pain and not the GeForce. I ran FO3 & FONV with 2x EVGA GTX 480 1536MB, 2x EVGA GTX 580 SC 1536MB, 2x EVGA GTX 295 RE 1792MB's, HD 6990 4096MB, HD 5870 1024MB, 2x HD 4870 1024MB, 1x HD 4870 Dev Board 512MB & 2x HD 2900 XTX 1024 MB Rev.A13 and all cards ran it fine, but the games did however flaw themselves by crashing on all cards, the crashes were random, it's that hey had nothing to do to with the VGA card drivers but the game it's self had the flaws it took months before Bugfesta did something about it, I just wasn't bothered buying their unstable products ever again , thus I lost interest.
 
As for benchmarks I do do that boring stuff, they never really interested me, as long my apps run fine, I don't need any nonsense benchmarks to prove me the better, it's that I know what is best for me, that is all what counts, so basically I don't care much about running benchmarks.

Sweet! I didn't know they had internal sli cables! Seems a bit janky to me....cheap even...
