@nafets - thanks for the markings of 1/2/3, and just to make it complete.. Is this what you ment about heating?
Yes, those are not a source of problematic heat on the HD4870, as I described earlier. The 5 VRMs to the right and resistors (possibly not the correct terminology) to the left should be heatsinked and actively cooled for proper heat dissipation...

5 VRMs, meaning 3 in black, plus those 2 on which "purple arrows" are showing, right?

Thanks.. I've just measured a bit, and seems like this VRM heatsink that comes with Accelero S1 should fit after minor modification (new holes for screws)

-


But I've forced this thread offtopic way too far, sorry ppl :shadedshu

That VRM heatsink works great for the HD4870, and provides a very useful solution to cooling the 5 VRMs in a straight line. I used it from from the Accelero S1 Rev. 2 package and along with my TR HR-03 GT.

I hacksawed off the two ends, as they are just a bit lower than the rest of the heatsink, and interfered with the proper contact of the 5 VRMs.

Removed the stock thermal pad (it's junk), and put on some Sekisui 5760 thermal tape. This holds the VRM heatsink on the VRMs very securely.

Mount a fan in the area of the VRM heatsink, and you should be good to go.

I have a small problem, can anyone tell me what is wrong here? Vista 64, cat8.8 beta (8.54). I don't have all the readings here? Is it cat 8.8 beta fault?

If you're using AMD Gpu Clock Tool to set your lowered GPU/MEM clocks, then the VRM monitoring is mysteriously disabled in Gpu-Z.

Try using the latest beta of Ati Tray Tools which also allows for setting lowered GPU/MEM clocks (and voltages) and for the most part, concurrently shows VRM monitoring in Gpu-Z. There are only a few certain instances where it doesn't show while using ATT...

That's unfortunate. ATT lacks ability to over/underclock both cards in CrossFire setups.

One more reading that needs more info, or better yet - fixing.

Voltage is always shown as 1,263V, even though BIOS has lower volts, and real volts change, and even when I change them through Ati tray tools (which also monitors voltage "from driver" yand there they do change on monitor; not sure if it actualy checks driver for voltage or not, but display says so).

But in GPUZ it's always 1,263V .. So is this a fixed number? Shouldn't it be reading VRMs for that value as well as it does for Amps?

If you could fix this, it would be great :) Specialy since there are now promises of a higher-voltage BIOS for 4870 cards - directly from ATI(?!) :-O

EDIT: Btw, that BIOS really ups the 4870's voltage by roughly +0,02V under load :D

yes, i can add logging. give me your wish list what features you want
Soo, except features asked for above in posts #21,#24 to #26, and that thing related to voltage readings in my previous post, I have one more request regarding 4870 cards.

I've found out that GPU-Z polling causes stutters in Vista, and very noticable ones as well. I've also learned that it happens because of the way RV770 sensors are polled (an no way around it). So could we have two new features that would lessen the effects of this polling:
- give us option to enable/disable polling for individual sensors (like checkboxes or on/off buttons besides every reading would be fine)
- give us option to adjust how often readings happen, so we can put it to every 10 seconds or something like that

Also, this could be related to fan spinning up for a moment to 80+%, as apparently while reading sensors you have to "switch" the source sensor, and if at that moment cards fan controller polls for temperature it can get a wrong value.

These infos above are based on information that Unwinder gave over here, and on my conclusions after that. So it's not written in stone, I could be wrong.. But I'd be gratefull if you would tell me what's your opinion and if you've got any different informations about this stuttering issue..

EDIT: Oh, and sorry for double posting, but I doubt anyone would be reading this thread after 6 days of inactivity if I've just edited my last post :)
