mcw60 compatible w/ ati 4850?

[binormalkilla]

I have two 4850s en route.......I'm really excited to see what these cards can do under a high end water loop. Any results from you guys running them on the MCW60? I'm going to use the Swiftech copper BGA RAMsinks on the memory and VRMs along with a few 120mm fans in the same fashion as my 2900XT setup. The VRMs get HOT with overvoltage....

here is my mcw-60 installed on 4870 (might as well be a 4850), its voltmodded too

Nice idea how you modded your card, but hey, RMA and resell value took a bad kick

And do you really think the radial fan you kept is useful? I think normal case airflow should do it with less noise

well if ive already voltmodded the thing there aint much sense in saving the stock cooler

I don't know if a d-tek unisink like product will be released, but I am fairly sure we will be seeing an "iandh" ramsink like product for the 4850 in about a week.

I don't suppose you have a revised timetable on these, do you? I checked the usual stores and haven't seen them up for sale yet.

when mounting the WB do you use the backplate? it looks it's going to break some components on the back of the card. i'm refering specifically the rubber on the backplate. anyone removed it?

i left the rubber, my card it's runing cool, 30ºC GPU load. but i'm having strange stability issues, 3dmark 01 e 06(haven't tried others) strangely crashes during runs. tried different drivers with same results, and in any case games are running fine

i suspect of the backplate rubber. anyone confirm?


tried card's stock backplate without success, mcw60 screws dont match

[jonny_ftm]

Maybe VRM overheating issues like with the 4870?

[roubagalinhas]

i have heatsinks on mosfets, temperature is not an issue, i guess

ati tool doesn't even start
tested with rthdribl and furmark, they're ok. games are also running fine

idle


load

Use stock "backplate" that came with the card instead. I'm currently using it with MCW-60 and it works perfectly

You should get some plastic/paper spacers [~1,5mm] between stock backplate and pcb.

Promised picture

i've remounted the WB using stock blackplate and zalman's Rubber Rings

used two on each screw

the problem persisted, 3dmark = crash during runs

so i remembered of checking manually pcb components
memory heatsinks were very hot to the touch, despite the temperatures displayed on gpu-z

solved the problem by using a fan blowing to the card
strangely the temperatures remained almost the same
