Is the MCW60 compatible with the 4870X2 ?

anyone with personal experience with updated tuning software for the 4870x2 ? ATI tool doesn't seem to work, neither Riva Tuner

you can do the fan hack in the profile like the 4870/4850 and can clock to CCC limits of 800/1000. Using AMD Clock tool resets the fan, RBE 1.1.3 you cant set the fan profile either :/

Don't be surprised if the hack doesn't work. Doesn't work for me on the latest betas 8.8 (8.54's)

I'd rather buy your unisink. The stock plate looks fugly. Make it teh sexy Gabe. :clap:

We'll have pictures soon.

I am also taking this oportunity to announce the release of the MCW60 Rev2.

As many had guessed before, we upgraded from the 1mm pin matrix to the Stealth 0.6mm pin matrix. This is long overdue some will say, and I answer your'e right! The Stealth proved to be the best performing block on the market last year, and I expect Rev 2 of the MCW60 to follow suit.

We are shipping Rev 2 now, and the price remains the same.

So two of them will fit on the 4870X2? How does the Rev2 compare to the D-tek GFX v2 block?

Gabe & co, sweet works.

Swiftech rocks uh? :)

So how is the progress going on the 4870X2 kits?
Any ETA on them?

I also ran my 4870 for some time using the stock baseplate with the fan off as Gabe has done here and had no problems.

That said, I'll probably let Gabe take this one because I do better on my other products such as the radgrilles anyways... I've really only continued to make them as a favor to the community; the original 8800GT set I made was never intended for anything other than personal use. They've actually become more of a nuisance than anything for my production shop as they've taken on some very high volume jobs in the last few weeks.

Either way, I've been too busy playing with my new 65" Mitsubishi DLP TV and PS3 to spend much time on the computer business. :yepp:

you should start doing these awesome ramsinks for ati cards too, especially the 4870 and 4870x2, i don't want to spend so much money on FC blocks as i switch my vga cards pretty often and my mcw60 did a great jod so far (3870s already came with copper ramsinks + pwm cooling :D)

The mount is possible because the spacing of the holes that fasten the MCW60 housing to the base plate is exactly the same as the 4870x2 mounting holes. note that this does not apply to the 3870X2 unfortunately, as the card mounting holes are 1mm less center to center distance than those of the 4870X2. so I'd say we really lucked out on that one since the 4870 is expected to have much more success than the 3870 (sorry 3870 owners).

For testing purposes, we found it possible to buy off-the-shelf hardware to install the 60 (original or rev 2 doesn't matter) on the 4870X2. the final hardware that we will release will be customized to ease the assembly for the average user, but for those of you who cannot wait until we come out with this mounting pack, here is the shopping list.

(4) 2-56 x 7/8" socket head cap screws
(4) 2-56 nuts
(4) #2 x 3/16 OD washer
(4) 2-56 thumb nuts
(4) pcs 0.250" long of insulation stripped from 12 AWG electrical wire

note1: 2-56 screws are necessary to be able to re-use the ATI GPU braces (highly recomended)
note 2: insulation is needed to center the screw in the water-block holes

all the hardware is available at www.mcmaster.com


Re. memory and mosfet cooling
I could have peppered the card with MC14's, MC21's and what have you, but it occured to me that since I was re-using the GPU braces, I could also re-use the back-plate, and why not, the front plate. The back-plate required no mods whatsoever, but the front plate required a little bit of machining to provide clearance for the two 60's. I did that on the CNC, but I think that this is also easily feasible with a dremel tool.

The above solution is also interesting from a testing standpoint, since it will demonstrate that the stock "heatsinks" (if you can call them that), actually let's call them plates, that the stock plates allow the card to run flawlessly without even the fan plugged in (and without the cover). In effect, I decided to test the unit without the fan, which is worse case scenario, and let it run under furry cube for hours to see what would happen.

Here is the modified assembly without the 60's, and the card with the 60's installed. Note that I have two different sizes of fittings on that pic because I wanted to show that it is possible to install 1/2" fittings by recutting the pins directly underneath the fittings and the card was getting ready to go to the bench, which uses 3/8" tubing.

Finally here is a screen shot of the temps under furry cube load (37C) . Also note that as usual on our bench, the coolant temperature is kept at a 30C constant.

Altogether, this looks pretty good. Now we have to design a true aftermarket heatsink for the card, which we'll begin to do next week.

This information concludes my participation to this thread for the time being, as I now have to get busy with engineering, among other things. Please be patient, and don't PM me with questions, as I won't be able to answer until we advance further into this project.

One last thing to the modders out there: I haven't done it yet, but I think it is ALSO possible to re-use the stock cover by grinding the upper portion of the lips of the 60 inlet/outlet (about 2mm interference), as well as cutting four holes to allow passage for the fittings/tubing. I'll try that if I find enough time to have some fun..

Just a quick question, but do you think it would be possible to come up with a top for the MCW60's so that I can screw in a barb at 90 degrees, or frankly just built that way stock? I would love a GPU only blocks for my 4870x2's (yes, plural) but I don't like full coverblocks so a GPU only block would mean having stange tube management unless I went with 2 90 degree angles, which franly I would like to avoid as the block as a "built in" 90 already

That being said I fully understand that there may or may not be enough volume for such an item, but even if you sold this top w/mounting kit alone seprate from the MCW60-R blister packs I think you would get many sales. I know you would get atleast 4, if not 6 from me :)

thanks for the info gabe that's great news :up:
love my 60 block :D

Still haven't seen your mounting kit or unisink anywhere yet, not event on swiftech.com

Is there going to ever be a unisink for the 4870X2 ?
And what screws do I need to mount my 2 MCW60 on the card in the metric system ?

I find it damn hard to find any screws made by the inch. :(

Thanks

It's the Caldera system, it's in another thread. I'll link it here in a sec.
