I flashed a 5850 with it, does 900/1300 perfectly stable at 1.174v

[M-XXXX]

I'm using 5850 and 2 monitors and I have flickering problem I have tryed and flashed with 5870 bios (the newest one) but it did't helped. Is there any solution?

newes ATi 5870 bios is the best for daily use air cooled.

I didn't like Asus bios, worse OC then MSi even using 1.40v and more unstable.

I've got 1 ati saphire 5850 stock settings and an OCed AMD 965 be c3 @3838mhz. I busted through 20k on 3Dmark06.



anyone find the 24/7 OC for the 5850 on air yet? If so please share your settings and programs you used.

I'm thinking of getting another 5850 and run them in crossfire later in the new year.

Since running that test above I finally got a hold on my 965 oc. I've got the NB voltage down to 1.3 @2800mhz and the cpu voltage is at 1.4 stable. I also managed to get my ram running correctly. So I should test it again! =P

I have an odd problem that pops up once in a while.
I have a HIS 5850 that would not overclock with Afterburner until I flashed with a MSI BIOS. It now overclocks to 1000MHz/1200MHz @ 1.237v.
But from time to time I hear the fan spin up and inside the Afterburner Monitor the GPU voltage is pegged at something crazy like 1.6v which is really odd because the voltage slider stops at 1.35v
The only way to fix is a reboot or reset to defaults and reapply overclock.

Has anyone else experienced something like this?

[nickless]

Can someone show, where is the HD5870/5850 vgpu measuring point?
Thank's!

[Dami3n]

30k broken and almost 31000 gpu points, not bad for only 2 cards

[alyns]

Hello and happy new year 4 all , i need some help pls . i buy a new card Sapphire HD 5850 1024 MB and i flash the bios with the new ati bios ATI HD 5870 1024 MB BIOS 2009-11-12
i made some tests with the 5870 default clocks 850/1200 ,and i have only 2 problems
1- mouse cursor is transform randomly to a dot line " i cant make screen shot with it so i made photo with my phone" ,
2 - i have dual screen , one screen have flicker problems probably related to the default IDE 2d core and memory clock ,but when i have 1 screen i dont have flicker problem.
so if anyone now the answers to this 2 problems pls reply .
Thanks and Regards .

vgpu 1.2500 to touch GPU 1000

[ChaosAD]

Vantage i7@4.5Ghz, xfx 5870@1000/1300@1.2v, will try to push a little more to break 22k. Is this good?

[Gaul]

up...all on air, cpu and gpu

[M_T_M]

If you mean this new ATI 5870 bios, yes, it works with HD5850. I've tried this bios, but if you want vcore above 1.35v (what is MSI Afterburner limit) you have to flash the card with Asus 5850 bios and use Smart doctor for up to 1.5vcore.

So you can flash a 5870 BIOS to a 5850? Interesting... What's the point of that though? Just ordered a 5850 today and have no idea how to overclock it. CCC limits, MSI voltage tool, unlocked BIOSes, BIOSes for different video card models... WTF! What happened to Riva tuner + soldering iron?

[nickless]

Everyone can flash a 5870 BIOS to a 5850 The point is that 5870 bios has a little bit higher GPU and RAM voltage, also RAM timings of 5870 allow higher frequency compare to 5850. So if you flash your 5850 with 5870 MSI unlocked or Asus bios you will have higher stable stock settings 850/1200 and higher CCC limits.
Riva tuner not support 5800 yet, but you can use MSI Afterburner, it's based on Riva tuner.

So, what options do i have to my Sapphire 5850 considering 1,5vcore from SmartDoctor, 5870 Bios with 5870 default clocks and memory timmings?

Asus HD 5870 1024 MB BIOS only?

http://www.techpowerup.com/vgabios/5...24.090915.html


or ATI HD 5870 1024 MB BIOS

http://www.techpowerup.com/vgabios/6...24.091112.html

should work with SmartDoctor and it's better?

Have, those two, same memory timmings?

I didn't like Asus bios, worse OC then MSi even using 1.40v and more unstable.

Did you mean 5850 or 5870 bios?
Should this happen, are they really different at this point?

[alyns]

can anyone help with my questions above ? .have anyone have thats problems like me ? .thanks

5870 bios. but maybe that was just here.

Not just you, I have same behavior with a 5850 Sapphire, when adding Volts with Afterburner the 5870 MSI BIOS is more stable than the Asus.

A minha é uma Powercolor...there was no way to go higher then 1010Mhz, even using a very good CoolerMod on it @ 50C Full-Load 1.35V, 75C for VRM

I have a decent one, runs 1000 @ 1.25V and its benchable up to 1050 with stock cooler.

Someone, please..

[nickless]

Someone, please..

So, if you want to use Smart doctor with non Asus 5850 card, you have to flash it with Asus 5850 bios. If you flash your 5850 with Asus 5870 bios, smart doctor don't recognize the card. It gives an error "Can not find video cards information" - тested by me several times without success and now I'm with Asus 5850 bios and i can set vgpu up to 1.5v, but no one answer me until now, where is measure point on the PCB to check with DMM is this 1.5v real ?!
If someone can modify Asus smart doctor to work with 5850 flashed to 5870 it will be great, but I don't know if it's possible.
