a long time back AMD said they were very happy with the die's and yield....not the type of thing You say unless things are going much better than expected

Doesn't look like rthdribl scales that well with GPU since I get pretty much the exact same FPS on a stock 4870.

The same settings you have it set to in your screen shot.

interesting.
Anyway I use it for stability testing, not benchmarking
Yeah it gets the card nice and hot, was just surprised that 800MHz on the CPU and almost 200MHz on your GPU doesn't do anything/much for rthdribl
This is how it's running on my card which appears to be the same res/settings as yours.

even looks like you got more fps
Looks good mate,
What are the chance of getting 900mhz on the 4870?
Or don't we know yet?

900mhz on stock vGPU? nil
with pencil mod? Just as likely as the 4850 since they use the same chips...in fact the 4870 may clock even higher because it has a very fancy voltage regulation circuit. Time will only tell though as I don't think many people have 4870s yet.
Have you a pic of the pencil mod?
whats the spec of your rig?
Ok finished this cooler !....still got the second one to do 
original Saph bios desktop 63c load 86c
My fanfix bios Max load 76c....but fan is only running slowly (fine for stock cooler
)
quick 2nd fan mod bios desktop 48c full load 65c and fan is audible but not loud
OK strange things are happening this sapphire bios seems not to have powerplay power states or a fan lookup table like Your bios (how did You get that into Your bios ?).the fan table
I will check out the other makes bioses and work out whats happening
Quickly tried You settings in My bios a no go really ! seem I can only clock at 670/1040 may be the 1.084 volts the bios is set to ! I need to look into this a bit more
So I think I will be able to get these 2 cards running quietly 45c desktop and 65 max, although I'm having a play as I have crossfire I don't really need the cards to run more than 650/1050
670/1058 is about max for this card with the better cooling as a reference thats 14757 marks in 3d2006 sm2 5203 sm3 6648 no cpu

Im having a few problems after flashing a new bios (700/1000) on my xfire cards. They were fine yesterday but they are definatly not 100% today. Ive seen a few artifacts dots in 2D 
Its started taking a while to load GPUZ like below. I have to change to the sensor tab and back to get it to show properly. it never did this yesterday.
Also my second card is only running at PCI-E x4 , yesterday it was x8 but shouldnt it be x16 on a X38 Asus Maximus ?
My first card looks ok , once gpu-z decides to load.
Ive flashed back to stock bios's but it not cured it.
Ive tried upping the northbridge to 1.5 as i heard it could fix the pci-e bus problem.
i dual boot between XP and Vista and its the same for both. Maybe one or both cards are on there way out. ill try them individually.

Hey gurusan well beside You I now have a couple of quiet cool running HD4850 
Have You explored the extreems of downclocking/undervolting in 2D clocks
I'm having limited success, Don't think as i've said before you need mega low clocks just low volts... It all gets tricky when the power modes switch ?
