Replacing the 5800U dustbuster
 
I'm considering picking up a Zalman ZM80D-HP to put on the BFG GeForce FX5800 Ultra. Has anyone had any experience with this heatsink on the 5800 (or any other Nvidia card, for that matter)? Most of the reviews have people putting it on a 9800 Pro and it seemed to do a good job of cooling the card. Think it'd be worth a go?

My only worry is exactly how good or bad the ZM80D-HP is at cooling memory... the 5800U really really requires GREAT cooling on the memory, and I'd actually be a little afraid of anything other than copper touching the hot DDR2 of an nv30...

Cool those DDR II RAMs!
 
Find RAMsinks that work for DDR II before you purchase any third-party GPU cooler for a 5800 Ultra!

The stock copper is much-needed for proper thermal dissipation of DDR II heat. DDR II RAMs on 5800s run extremely hot. Off-the-shelf DDR I RAMsinks do not work for DDR II.

Third party RAMsinks did NOT work for DDR II with my "expendable" 5700 Ultra. The 5700 Ultra DDR II with 3rd party RAMsinks never booted into Windows without artifacts. I restored stock cooling after only 15 minutes of testing because 3rd party RAMsinks were so inadequate.

The DDR II RAMsink assembly off a 5800 non-ultra should work on a 5800 Ultra. My water-cooled 5800 non-ultra GPU is stable with DDR II RAM clocked at 1.2 gHz with the stock RAMsinks.

Right, thanks for the input, all. I guess I'll keep looking...

I emailed Zalman, they said the HM80s don't touch the RAM, so I gave up on that idea.

I do have copper RAMsinks from a 5800 OTES I could give you for your modding project, PayPal me $10 to cover shipping and handling and send you the whole card. (minus OTES, which I stomped)

EDIT: Actually, it won't cost $10 or be any special packing for a dead card. Make it $5 to cover my ship costs and it's yours.
