Anyone here have a gigabyte 4870? Do you know what mem modules they use? How does the card clock?

So Techpowerup is mistaken in this review?:
The reference design HD 4850 cards all used a three phase power design which tended to get quite hot. HIS went with the four-phase route which distributes the load over more components.

Yep.
Infact, that HIS card is a reference board - just blue that is. The card's a carboncopy of Powercolor or MSI.
edit:
The phase controller on HD4850 is the uP6201 which supports upto 2 phases...
edit2:
Good thing you mentioned about the TPU article... I'm an editor there so I can correct the article. edit3: Aww... W1zz has locked the article. I'll just notify him.

You were not supposed to see this.
Room temperature was 21 degrees Celcius and the card has an 80mm fan @ 1000 rpm pointed at it. Mind you that 700MHz for the GPU was pre voltmod and pre bios mod.
If I remember correctly the temps with the orginal stockcooler were around 90 degrees for the GPU at full load before I did the mods and all
Only had it running with the stockcooler for one day
Nowadays it's been voltmodded to 1.37v for 850/2350 during load, which gives me around 40- 43 degrees stressed.

I'll probably solder VR's for every IC leg and start to test which changes Vgpu
I won't give up, I have LN2 pot for that card waiting
Vmods - what can possibly go wrong? ©
ceemic,
Try the pin in top left corner of the 16pin "AP-AG" in NBF's pic...

largon, tnx again!
Use 100k or 200k VR. I'll do the mod ASAP and report back

I'm having some issues here,my card works just fine with AtiTool,no artifacts at all,also using FurMark while in XtremeBurn it's just ok too,but while playing Crisys it will often during game play just hang the program,with some less times hanging Windows(with a blue screen,talking about the driver entered in a loop),any idea what to do here?My sensor(mainly MemIO)is really hot,while in xtreme burns it gets up to 95,and while in AtiTool up to 90°C,but as far as I know this card can take that just fine,can't it?
Also my voltage and clocks are not that high,760/1078(HD4850)
EDIT:Problem solved,I bought a Zalman VF900CU to put on it and apparently it doesn't have a good contact area with the die with the general amount of thermal paste that is needed to used,I added a thicker layer and now I'm getting much better temperatures.

I haven't got time to mod my Asus, but friend of mine gave me his two Gainward HD4850 512MB Golden Sample
Other pics: http://ceemic.pri.ee/hardware/hd4850gs/
Def Vgpu changed (idle/load) 1,194V/1,214V -> 1,207V/1,221V

G-UNIT91, what profile?
NapalmV5, what Vgpu? 3D stable?

i wish.. can bench anywhere from 900-940 core/~1090 mem
havent monitored voltages
