Palit Radeon HD 4870 X2 - VID487x2 Compatibility?

Postby FlyWheel » Wed Oct 15, 2008 2:42 pm

I recently got a VID387X2 cooling block. I bought an ASUS 3870 X2 video card, and while it matched the general layout, there were two additional DVI connectors which the reference design did not have. Some chips seemed thinner and the two addition headers needed trimming. I also had to grind off some of the pads on the block where there were no longer chips and other stuff interfered. Anyway, I got it all matched up and it looks like all the right pads are touching.

Problem is, I did all this before I was able to check if the card actually worked :(
The card goes away part way through the POST. Maybe like it thinks it is too hot?
I tried it with the fan attached so it thinks it is there also. Could be the Tyan i5400PW MB won't support it.

So, now that the rest of the 'puter is operational (pretty much) I was thinking of getting a 4870 x2 card. I will stick with one that is close to the ref board (I see the AMD logo on the base of the card in the pic of the waterblock, same as the evaluation board in one of the early reviews.) Question is, is the Palit Radeon HD 4870 X2 compatible with the block? It looks like the ref board.

I have (re)learned many hard lessons on this project. I will make sure I can get the card working as delivered before any mods are done. I would like to get a cool cooled card on there so I don't have to alter my plumbing. :mrgreen:

The ASUS 3870 X2 "GeCube" adds 2 additional DVI's on a daughter board that do conflict with the full-coverage water block. Fortunately, we have not encountered any conflicts with the VID-487X2 and current HD 4870 X2 cards (yet).

Some video cards, more recently some HD 4870 1GB cards, have fan detection that will cause boot issues with nothing connected. We will begin offering simple fan plug jumpers to bypass this for our VID-487 shortly.

Hello Again :P

This system is the longest build I have ever done. I have had lots of other stuff going on since my last post.

I got 2 Saphire 487 x2 cards. After making sure they worked :mrgreen: I put the VID 487x2 blocks on them. The blocks fit great. In final assembly, when I put BOTH boards on the MB, I could get no post info on the screen. I tried attaching the original fan, no diff. Took the power off the second board and removed the crossfire and it worked. Took the fan off and it still worked :roll: After reading my original post in this thread, I realized that I did not let it go very far through the post. I will try and let it go longer, maybe, before I re-plumb the system, because I still may need the fan signal. I had ordered the 2 slot VID block connector (because they skip one slot of course). I do not know if you had those nice drawings on the part description when I ordered it, but I see now that I should have the single slot connector (DUH).

I am going to order that single connector. I will let you guys know how it all turns out :D

PS: When going through the post waiting for something on the monitor, if I waited for a while it was amazing how much heat was coming off those cards with no coolant flowing :o

Although I have never really read this happening on a skulltrail platform, 2 4870X2 in crossfireX did have the problem you described (no display when both cards are plugged in). In AMD's forums, they said that you can fix this by installing 1 card first, letting windows detect the card, install drivers, reboot, install 2nd card, repeat detection/drivers, enable crossfire. And, you have to use the latest catalyst and ATI drivers from their site.

I am not sure if I am reading this right, but are you running the HD4870X2 with the water block on w/o water running through the blocks? :shock:

If so, don't do it. Water blocks are designed to be effective in water, not air. And your cards are probably the hottest running cards on the market right now. So, there is a pretty good chance you'll kill your cards. If you are not water-cooling them yet, consider temporarily putting back the stock heatsink/fan.

As Freedom mentioned not having them plumbed up is going to kill them. A CPU can explode with the heat sink removed, video cards are essentially the same story. And not having coolant flowing through the blocks renders them useless and could cause the same thing to happen to your shiny new cards. Which no RMA would ever repair for you.

Yes, you guys are quite right. I was going to try letting it go farther through the post, but then I chickened out after about 7 of the 32GB of Memory was tested. I ordered the VID block connector and I will get it plumbed up before I go any further.

I figured I would try to get one card set up before I enabled the second card. It makes sense that the driver may have to be there already to get the crossfire working. I can't wait to start poking around at making a program to use those 3200 processors! (or even just try to play Crysis) :D

Hi There!
I finally got my connector last weekend (Jan 3). I ordered it on Dec 17 and koolance shipped it the same day. It should have arrived on the 18th, but it snowed here in Seattle. We kept getting snow storms through christmas. UPS put a low priority on regular ground shipping. But that is all in the past :)

I put the connector on and finished all the plumbing. Having learned my lesson, I double and triple check all the connections. I pre-primed a few areas before making the final connections in this Rube Goldberg contraption, then I powered it briefly many times while turning it every way but loose to get most of the air out.

I got it booted up and installed the latest video driver with only one card powered. Powered the other card, and it was found and the driver installed just fine. WOoHOO! It said it was using the crossfire too :D

Crisys really flies!

I have not checked the video temps with software yet, but the 3.2Ghz quad Xeons are running about 31C at idle. Running Crisys, the temps on the backplates of the video cards, opposite the cooling blocks go from about 98 - 100 F to a max of about 110 - 114 F under load. This is with the pump set at 9. The fans are on auto and usually run at 2 but I have seen it go to 5. One of the cards is 1 to 4 degrees F warmer than the other one. I thought about putting them in parallel flow, but I already had too much tubing in there. The Koolance power supply is the last item in the flow path, after the 2 paths are merged and it indicates about 98F under load. Because of the extra card taking up space, I also eliminated the H connection after the CPUs meant to balance the flow to the CPUs. The CPU in the path which includes the video cards runs about 1C hotter than the other. This may indicate there is less flow in that path. After I play with it for a while, I may try adjusting the flow with an adjustable clamp on the path with the coolest CPU until they are the same under load, or even slightly higher, so that more goes to those video cards.

Further updates to come ;)

Nice 1 thing i woudl start clamping hoses over 1'c. Gotta remember that they are not used equally by your software.
