And that is easily attainable with normal overclocking through MSI Afterburner. So why don't you just save yourself the trouble and risk of bricking a card and OC your cards normally?
Yeah I know about and tried using those programs but with the non reference cards not having a voltage regulator I couldn't up the voltage. That sucked so I flashed my bios. Runs great with the .025v increase at the 6870 clocks. My question is can I do the same thing to my diamond ( if I brick it I can always reflash it with the stock bios right? I made a back up) and can I run them in crossfire?
You should be able to do the same things with your Diamond. Go to Techpower up's VGA BIOS database. They should have BIOS's there for you. You could also download the Techpower Up BIOS modding software as well. And you can modify your BIOS and set the voltage manually from there.

Lol, while I was waiting for my netbook to install Lubuntu, since my home pc that everyone uses has not got a powerful enough psu I still have my 6870 in its bag so I got it out and started spinning it by its fan... Oh the irony of it all... This card will haunt me forever.

I know what you mean. tonguesmiley.gif These 6850's have left such a mark on my heart that I am spending money to get them under water to just keep them a b it longer and get more speed from them, when the money could have been better spent on a 270-280x! kookoo.gif

Same with me, after all the trouble they both gave me I just can't get rid of them...
Was gonna buy a GTX770 for 200 euros and sell them for 75 euros each, but I just wasnt ready to move on.
Still using them to game and they do not disappoint!
Im reaching the point in which if I dont upgrade anything Im gonna leave everything as is and build a new system to replace this one tongue.gif

They use the same cooler, same SKU. Different components.
The PCB on the newer one is crap when compared to the older one, I can't get it to clock anything. Its voltage locked also.
I'm gonna put the old picture I took of them up again.


Top one is the newer card, PCB is longer similar to 6870 PCB but the VRMs etc are plain crap. Can't overclock to 800Mhz without artifacting.
The bottom one is the older 6850, use it as my main card. Overclocks nicely to 1Ghz core and 1150Mhz memory, temps don't go over 76~ on auto fan profile in gaming.

Getting them to play nicely with each other was another struggle, when I bought the both of them I started having all kinds of issues that occupied my free time for over a week. I couldn't get them to crossfire.
They both worked as single cards, I had to play arround with configurations to see what I could do. I believe it was driver related because I don't have any issues with them anymore.
But initially I ran the bottom card as my primary display and the top one as slave, if I turned it arround they wouldn't allow crossfire.
Played with their Bios and changing the clocks to see if I could get higher clocks out of them with voltage regulation... The newer card acepts modifications to the Bios, the older one doesn't.
It stays stuck at 100/150 even if I change all the profiles to 900/1100mhz, I believe it might be driver controlled? Haven't looked much into it cause I just started doing that recently.

Also the older card uses Hynix memory chips vs Elpida on the newer one, the sensor list in GPU-Z also points to a major difference in the PCB as you can see in the attached pics.


The card with a bigger list of sensors is the older one, you can't see it on the screenshot but it also has VDDC current reading, and two VRM temperature readings.

My Gigabyte 6850s are the same. I haven't removed the heatsink, but the older one has more sensors and more headroom, the newer one has locked voltage control.

The PCB on the newer one is crap when compared to the older one, I can't get it to clock anything. Its voltage locked also.
I'm gonna put the old picture I took of them up again.


Top one is the newer card, PCB is longer similar to 6870 PCB but the VRMs etc are plain crap. Can't overclock to 800Mhz without artifacting.
The bottom one is the older 6850, use it as my main card. Overclocks nicely to 1Ghz core and 1150Mhz memory, temps don't go over 76~ on auto fan profile in gaming.

Getting them to play nicely with each other was another struggle, when I bought the both of them I started having all kinds of issues that occupied my free time for over a week. I couldn't get them to crossfire.
They both worked as single cards, I had to play arround with configurations to see what I could do. I believe it was driver related because I don't have any issues with them anymore.
But initially I ran the bottom card as my primary display and the top one as slave, if I turned it arround they wouldn't allow crossfire.
Played with their Bios and changing the clocks to see if I could get higher clocks out of them with voltage regulation... The newer card acepts modifications to the Bios, the older one doesn't.
It stays stuck at 100/150 even if I change all the profiles to 900/1100mhz, I believe it might be driver controlled? Haven't looked much into it cause I just started doing that recently.

Also the older card uses Hynix memory chips vs Elpida on the newer one, the sensor list in GPU-Z also points to a major difference in the PCB as you can see in the attached pics.


The card with a bigger list of sensors is the older one, you can't see it on the screenshot but it also has VDDC current reading, and two VRM temperature readings.
Man that sucks. Yeah ever since I had the Sapphire 6790's I shied away from their products. The cooler was not good. Loud. Before that I have a Gigabyte "Batmobile" 5770 and a Saphhire 5770 together and they didn't like each other either. I got these MSI 6850's secondhand. One is also a newer PCB revision from the other. But they both clock well and they play well together. I love MSI cards. And I will be sticking to them from now onwards. thumb.gif

My experience with this is that you either buy reference when they come out or you wait for aftermarket versions of MSI/Asus. If buying Nvidia then Evga.

So i started having random lockups where I had to reboot. I am pretty sure my oc is stable, the only thing I changed was flash to the 6870 xfx bios, I flashed back to the 6850 to see if it locks back up again.
Anyone have any ideas? Im sure if it locks up again It was the bios flash but if it doesn't does that mean the 6870 bios was unstable on my 6850?
