Sapphire HD 5830 Extreme 1GB problem

post #1 of 5
Thread Starter 
Hello all,

I just bought a Sapphire HD 5830 Extreme edition for a client. I popped it in a Asus P7P55D-E Premium motherboard with an i7 870 and everything went fine. I installed Windows 7 and all the drivers for the motherboard and video card - latest catalyst 11.5 from AMD's website. Green and white spots started appearing 20-30 mins after Windows 7 and all the drivers were installed. I started up Bad company 2 and everything was fine - no spots - decent fps. I exited from the game after 20 mins and 2 white spots began appearing again. I tried different video cards (I had an 8800 GTS, 2600 PRO, HD 5870) and there was no problem (I tried the 8800 GTS last and removed drivers + used driver sweeper to ensure it ran properly). My friend and I think the card cant hold the clocks and I was reading on guru3d that this happens when the overclock is too high. The clocks are stock as reported by GPU-z and Afterburner. I cannot change the voltages. It seems there isnt enough juice being feed to this GPU and its producing these spots. I'm going to take it back to the store (canadacomputers) and try to replace it - hopefully they can produce the same results and give me a new one. I did try it on other PC's and the same thing occurred so I guess something is wrong with the card.

Any suggestions/input/ideas?

Get a different one, sounds as if you did everythin right to confirm that it is indeed hardware and not software related

Went to canada computers - the guy tested it for 5 mins and was like "OHH NOTHING IS WRONG SORRY BUD, IT'S OK". I showed him pictures but he told me it was my 120Hz monitor that was causing trouble - I told him I ran it on my other 75 Hz 1400X900 Acer monitor but I guess he didn't hear me. Anyway, I got home disappointed and I started reading up on BIOS flashing. I used a combination of the Radeon BIOS flasher and ATI Winflash to do the job. I increased my voltage to 1.063V from 0.95V idle and played with the clocks. I botched up the process the first time and got a black screen but luckily I used Sapphire Trixx before and got a copy of the BIOS. Anyway, I used my 2600 Pro PCI-E video card to get back in and I managed to flash it with the default BIOS. Then I tried my luck again except I did not touch the clocks this time and only increased the voltage. It was successful. I see 2 little specs every 1 hour or so for a second and it disappears - but its on the taskbar and it doesn't bother me. Anyway here is a guide I cooked up, it can probably do other lower series as well:

How to flash an AMD Radeon card (5800 series [confirmed Cypress] and up)

Note: To do this safely make sure you have 2 video cards (PCI-E preferably) and a motherboard that can handle 2 cards - this will help if something goes wrong

Download Radeon BIOS Editor from TechPowerUp. Also, download the latest version of ATI winflash from their website. If you have a Sapphire Card (maybe some other brands can work too) - use Sapphire Trix to dump the bios - it will usually end up as a bin file. If you can obtain the correct version of your card's BIOS from the internet - do that. Open up the Radeon BIOS editor as an administrator. You have the option of acquiring the BIOS using ATI Winflash. Hit Analyze and select the card you want to dump the BIOS for and then hit Acquire BIOS. Make sure you point to the proper location first!


You can look through the settings in the Radeon BIOS editor after you hit Load BIOS and point to the correct BIOS for the card you want to flash. Now remember for special editions like the Sapphire Xtreme HD 5830 or non-reference 3rd party PCB's - most of them make sure their clocks are tamper-proof. This means if you mess with the clocks like I did once, eg. try to change the 2D clocks from 157/300 to something like 250/400 and try to flash it - this will NOT work due to a check. You will end up booting windows and have a black screen instead of the nice welcome screen. I will talk more about fixing this later. So try not to mess with the clocks unless you know for sure you can. What you usually want to do here is mess with the voltage. My Sapphire HD 5830 used to artifact at the 2D clocks and I used to get little green and white pixels on some areas of my screen after about 20-40 mins of leaving it idle or maybe playing a game and letting it idle. When some GPU load was there - the clocks ramped up and so did the voltage. So when I was playing Bad Company 2 - no problem. Sapphire did not do proper QC on this card and I hope it was an accident. So what I did was look at the other voltages. The 3D mode was 1.163V which was too much for idle. I looked at the UVD or media modes and saw 1.063V now I just replaced the low 0.95V with that 1.063V and that was it. I clicked the Acquire/Flash BIOS button, hit analyze, picked the video card and flashed it. Rebooted it and its running great. Just do 2 or 3 reboots to ensure it works properly. No more artifacting due to insufficient voltage.


Problems can occur during the flash process especially if you did not run as Administrator. Make sure you do not directly use the ATI Winflash tool as doing so can result in a bad flash. Always use the Radeon BIOS editor running as administrator and use the Acquire/Flash BIOS to have better safety. In case you got that black screen like I mentioned. Connect your second card into another PCI-E slot and hook up the display cables to that. Boot up and now you get the welcome screen. Run the Radeon BIOS Editor, get your original BIOS loaded and make sure you run as administrator before starting the Radeon BIOS Editor. Click Acquire/Flash BIOS, click analyze - pick the correct card and hit flash BIOS. Do not reboot. Shut down instead. Unplug your card you used to assist in the flash. Keep the original card in. Boot up and everything should be dandy. You might need to reinstall the drivers again.

Edit: In case anyone is looking for this vanilla HD 5830 Sapphire Extreme BIOS

is there a way to avoid black screen after editing default bios speeds for 5830 extreme ?

I would like to change speeds to 950/500 1.2v, but im getting black screens just like u described.

It's unfortunate that I found this thread after I messed with the clocks. Can you elaborate on the fix, please?

Thanks
