i would like to know which value your using for the volts in rbe1.11... i have all clocks up at 830 1100 and am stable in all benchmarks but the furbenchmark which causes a system crash....

I just bumped core to 830 on stock volts and it's running flawlessly, furmark included
core i7 920, gigabyte EX58-UD5, 4870x2
DDC3.2 > PA120.3 > DD4870x2fc > Fuzion v1 > PA120.2 > EK Res
5 seconds into furmark the pc crashes..... but it was fine the first night when we used the 64k bios accidently....
i benchmark as its what i enjoy doing... these cards are going to have to go back if everyone else is fine on stock voltage....
is this accurate... is everyone else just using stock voltage... and could you please say what stock voltage is.... stock on your card might be differant...
on another forum someone is only able to go to 800mhz core so you are not alone

then these cards have weak cores... its unacceptible that a 4850 can clock higher with same core...
? You are on stock volts, I'm on 1.35v and under water.

how do you explain other peoples success with these clocks volts and 4870's....
could be luck of the draw, could be heat, perhaps they have added some voltage in the bios.

thats what i'm asking m8... please let someone answer who owns the card... instead of blabbering on about your 4850....
I was wondering how are you guys getting the amd gpu clock tool to load up, I right click on it and " run as administrator" option does not show up. any ideas?

Cain, try editing w1zzard's fixed bios with RBE and setting the fan pwm to "recommended". Maybe your card is hot/unstable? It could just be luck of the draw like processors (pretty likely).

Unfortunately I think I've reached the limit for my q6600 in 3dmark, even a 3.68 ghz q9450 beats my cpu
@NKD. what OS are you on 32-bit or 64?
the cards wont even work at 790/780/760mhz... 755 and they are stable... the gddr5 is happy at 1100mhz... so i'm going to send these back tommorow... something is definatly wrong with these cards...
Before that, could you tell us which core rev you got.Originally Posted by purecain

Are there any other artifact scanning tools? I don't really trust atitool since I have had it give me false positives and false negatives in the past.
Dragothic in 3d01se and ATI-Tool are both great artifact scanning tools.

I ask because I don't get any visible errors in games or Vantage even at 840, but ATItool reports artifacts even at stock if I run it long enough.
I'm aware of the GPU only blocks working. I would like a full cover EK, XSPC, etc.
WhyExpensive, not as good, and useless when you switch cards.

Just a personal preference. I have an excess of radiator power. So I figure why not use it to cool the ram, etc? I'm aware that I won't get as good cooling as with a GPU only block, but that doesn't really bother me.
i'm sure it just said manufactured in taiwan... there was no rev info on the core.... where would that info be on the packaging...
edit.. i took 5 pics of the core and they are all blurred.... typical...

Increase the lighting and it should be easier to take non-blurry shots.
I should amend my above statement about water blocks - I wouldn't be against using a GPU block if D-Tek or others released a unisink style ram cooler.
Works fine for me without even hitting to run as admin on Vista 64.
I'm trying to get stable at 856mhz... 855mhz performs a lot worse than 856 for me, I guess because of one of those hidden clock jumps, but it runs a lot hotter... stock cooler at 62% eventually gets too hot. That's with 4400 RAM. 840 core performs well but 856 is a HUGE jump over it... also takes a lot less fan speed though at 840/4400. I think the RBE bios voltage does work though because changing it is affecting my stability/heat results... heat is the major issue
I can't confirm by how much, but I am now sure that changing the voltate in RBE does effect the actual voltage.
I increased it to 1.3v (slowly) and I am now artifact free at 790. 800 has errors occasionally, before there were tons of errors.
I wonder what the limit is for bios adjustment as I don't have a DMM...
