I started playing with my Asus 5850 last night, having had it on a mild 835Mhz core and 1025Mhz memory on stock voltages, it worked fine. I'm using the 10.3 beta drivers. I wanted to push it further and tested stable at the following settings:

Run1: 835/1025 stock voltage (1.087v)-3dVantage score: P12787 GPU:16117 CPU:7893
Run2: 835/1200 stock voltage (1.087v)-3dVantage score: P12702 GPU:16434 CPU:7555--unstable on second run
Run2: 904/1205 1.25 Volts with Voltage twk-3dVantage score: P13322 GPU:17223 CPU:7932--unstable on second run

Problems I ran into later:
Run3: 900/1200 1.25 Volts with Voltage twk-3dVantage score: P12822 GPU:17002 CPU:7379

**EDIT** 900/1200 was not stable......kept getting BSODs...Tried bumping the voltage to 1.3 and 1.328 and started seeing flickering and BSODs, also crashes in 3d Mark.

RUN4: 895/1195 1.25 Volts with Voltage twk-3dVantage score: P13144 GPU:17260 CPU:7662 stable settings so far...this may be my limit. I also had to bump up my RAM voltage to 2.00 V from 1.95 V

RUN5: 895/1195 1.25 Volts with Voltage twk-3dVantage score: P12989 GPU:17056 CPU:7571 ---lower scores, means this is still unstable...

RUN6: 880/1195 1.25 Volts with Voltage twk-3dVantage score: P13239 GPU:17067 CPU:7914 --Highest stable score so far...very low stuttering in 3d vantage Jane nash and New Calico.[/b]

RUN7: 925/1195 1.25 Volts with Voltage twk-3dVantage score: P13160 GPU:17378 CPU:7614 with E8400@3.9Ghz(433x9) --Highest overall stable score
Basically by finding the E8400 some cushion and down-clocking it at 3.9Ghz, I can now push the 5850 past 900Mhz with a stable score. I'll keep pushing and see what more I can get.

RUN8: 925/1175 1.25 Volts with Voltage twk-3dVantage score: P13183 GPU:17308 CPU:7687 with E8400@3.9Ghz(433x9) --As you can see, lowering the Memory slighty increased the overall P and CPU score when compared to RUN 7. Currently, I'm running on RUN 7 settings.

RUN9: 925/1175 1.225Volts with Voltage twk-3dVantage score: P13169 GPU:17310 CPU:7667 with E840@3.9Ghz(433x9)--stable

RUN10: 925/1175 1.225Volts with Voltage twk-3dVantage score: P13154 GPU:17288 CPU:7659 with E8400@3.9Ghz(433x9)--stable

RUN11: 925/1175 1.223Volts with Voltage twk-3dVantage score: P13308 GPU:17693 CPU:7633 with E8400@3.9Ghz(433x9) on Win 7 Pro--stable

This setting seems to be the best of both worlds for me: 925/1175 with 1.223V.

Vantage Temps: Idle 5850: 44C Max: 86C
Fan setting: Auto (20-30%)

Furmark temperatures:
1440x900 test:
Min FPS:85
Max:172
Avg:111

Temps:
90C with auto fan setting
85C with Fan at 82%
82C with Fan at 91%
82C with fan at 100%

From running these tests it seems my CPU is a bottleneck and is exhausting more or less at the 4.02Ghz overclock.

My temps are around 77-83 under load depending on how high I have the fan. My vrams are below 90. Both are acceptable for this card.
Click to expand...

Are these running Furmark? Or general gaming? I've noticed that with running Furmark, at 80% fan speed I get a max around 90C running 925/1175 with 1.225 Volts. If I run 925/1195 with 1.25V , the max temp is 91-92 at furmark, the fan needs to run to a 100% to keep the temps low....

While general gaming, the video card will never run this hot however....any suggestions? My case has little airflow in general and that will be a factor with the temps, but only while furmarking, my temps at stock settings also reach 89/90 easily. What's a safe temp setting?

I installed my 5850 2 hours ago and just finished my first vantage run after a quick OC at stock voltage.

850 core 1200 mem with stock voltage. 74c under load

It's an ASUS 5850 Open Box from Newegg for $220 shipped. I unpacked it from near virgin looking packaging with every accessory and protective interface cap. Heck, the tape on the static bag even looked untouched. This is the third time I've bought open-box from Newegg and so far so good.

I was nervous that I'd end up with a reject PCIe compatible space heater after my XFX 4890 refurb adventure but this 5850 is perfect.

Luckily those numbers were my goals when I bought it but I feared I'd have to bump voltage a bit and maybe go aftermarket on the heatsink. Fan never goes over 30% under full load and is barely noticeable over my case fans. I will be leaving this "as is" for a while considering I'm CPU constrained at this point.

General Gaming. I might get an aftermarket cooler, haven't decided yet

**UPDATE**see Original Post for updates.

Rock stable at

RUN11: 925/1175 1.223Volts with Voltage twk-3dVantage score: P13308 GPU:17693 CPU:7633 with E8400@3.9Ghz(433x9) on Win 7 Pro--stable

Of course these are Furmark temps, and in no way would you reach these temps with such fan speeds in any game or load.

gonna have to do some more bench testing but at specs in sig it's stable so far.

Using the 10.3 beta drivers this is what I get.

to OP, i should of been more clear, as far as i can tell, your only posting your GPU temps, what are your VRM temps?

You are kidding right?

If your performance dosen't keep going up . It's probrobly because your overclocking too much and ATI cards don't artifact they correct themselves.

Going to be doing alot of benchmarks tonight to see performance differences. At 1.175 volts 1000/1250. If i increase the later to 1300 is this much of a performance difference?? Afraid to go any higher. ITs furmark stable for 30 minutes and runs heaven benchmark flawlessly. Temps at 40% fan are 67 degrees celcius. I seen a 7-8 fps increase over stock 765/1125 settings. *this is i n heaven benchmark at 1680x1050 8aa 16x af.


below is stock vs 909/1200.

which tool are you guys using to overclock? MSI Afterburner? ATT?
RBE at the end?

I used Asus Smart Doctor initially, but switched to MSI Afterburner now. I'd recommend MSI Afterburner, it lets you save your oc settings, lets you save up tp 5 OC profiles, auto applies OC at restart, and also looks cool and has a few skins.

Here's my Desktop, using a 1440x900 extension of the desktop on my Acer, the right half is on my 24" 1920x1080 BenQ

825/1200 seems to be working fine with it, but two questions

1) how do you lower it back down to default idle speeds in 2d?
2) it doesn't let me muck with core voltages, is there something I should change in the settings?

I have modified the cfg file to get rid of the clock caps on core and memory :)

Hit the settings tab in Afterburner, it should then give you an option to unlock voltage control.

What brand of 5850 are you using? I didn't have to modify any cfg for my Asus 5870/5850, there were no caps for voltage or clock limits.

Exactly what I did. First I flashed to the MSI unlocked BIOS to unlock the higher clocks. Then I tested different clocks/volts with afterburner. Once I was happy I had a good stable combo I edited the BIOS with RBE and reflashed.

XFX 5850 XXX. Does using Afterburner negate powerplay?
Click to expand...

No. Your 2d clocks do not get changed. They are still 157/300. Load up Afterburner and you will see the 2D clocks when you are on the desktop. Powerplay has different registers for 2D and 3D. When you set the clocks in Afterburner you are only setting the 3D clocks.
