*** Official OMG I've finally got my 5850 thread **

[wolvers]

Yeah, I'm not getting VRM temps in GPUZ either.

 

[RavenXXX2]

Thats because the 5850 is not supported yet.

hehe, so why post it??

 

[RavenXXX2]

LOL, I didn't know until you pointed it out.

VRM hit 92C in furmark after about 90secs.

Heatsinks not enough so I'd better get a fan in there or a full block.

OK here's some more AA in crysis bench tool results and DX10 very high. For some reason it switches to 1080i 30hz when running DX10 which is annoying and was the same with the GTX260 IIRC.

Crysis Bench Tool -
1080p/All High/DX9 - 56avg,32min,70max
1080p/All High/4xAA/DX9 - 45avg,25min,53max
1080p/All High/8xAA/DX9 - 48avg,27min,57max
1080p/All High/16xAA/DX9 - 48avg,27min,58max
1080p/All Very High/DX10 - 30avg,18min,35max

So, over 4xAA it's not working for some reason. It look like it's probably applying 2xAA.

Block is on!!



Max core temp so far is 37C!! What app will show me VRM temps?

Gonna try some clocking now.

Thanks,

Does AMDGPUClockTool support the 5850 vrm read out?

 

[wolvers]

VRM temp 73C after 5 loops of crysis bench with 4xAA. Probably be OK for now but will hinder OC when volt modding bios appears.

 

[fornowagain]

Good chance this Zalman ZM-RHS70 will fit. Fixing centers look very close.

Won't start. Just says no valid devices found.

Could You not modify the original Ati Cooler base and fit the water block to it ?

Did You get the special version ?

For 3 quid it's worth getting one to find out. Thanks for finding that.

That leaves just one lowly one at the other end of the card? I think it'll still need a well placed fan in my build.

Just checking, v.0.9.26.0 ?

that works, but the voltage settings doesn't work

 

[wolvers]

Just checking, v.0.9.26.0 ?

9.8. I'll try 9.26.

 

[fornowagain]

9.8. I'll try 9.26.

That be it then.

I would think whatever passive heat sinks are used you will still require airflow across them, but that bolt on jobbie without pads will be way better.

 

[wolvers]

Yep, that's getting VRM temps now. Thanks.

Edit; Added the link to the OP

Yeah that's pretty much a given, passive is never really that passive tbh. A couple 7 volted 120mm fans across the bottom of the motherboard is what I always use. Silent, but enough air flow for ramsinks etc.

A bit like dnottis 5870 efforts on XS.
