***The Official MSI 5850 Twin FrozeR Thread***

[Marine-RX179]

ok, I'm awared that is already a 'Official 5850" thread, but since OcUK has now sold over 400 of the MSI 5850 Twin FrozeR since the £124.99 pre-order deal was out a week ago on 17th Dec, I think it deserve its own separate thread...kinda like how the GTX460 1GB HAWK has its own official thread. Ideally, the owners of the card can share some overclock settings and results here

Anyway, straight to my overclocking result.

Core clock: 950MHz
Memory Clock: 1250MHz
Voltage: 1.275
Max Temp: 63C
Driver: 10.12


Stability test so far:
Heaven Benchmark 2.1: Directx11, Shaders High, Tessellation disabled, 16xAF, 4xAA, Full screen
Results: 3 loops successful with no problem whatsoever

Additional info: core clock 950MHz would crash in under 10 seconds into Heaven Benchmark 2.1 with voltage 1.250

Important reminder: When we install the new CCC driver, the AA quality is defaulted to lowest, so we need to turn that back up to highest quality.

Update: Driver crashed when playing BFBC2, dropped the memory clock down to 1200MHz seem to be fine now...

Update: Higher overclock attempted
Core clock: 1000MHz
Memory Clock: 1300MHz
Voltage: 1.300
Max Temp: 65C
Driver: 10.12


Stability test so far:
Heaven Benchmark 2.1: Directx11, Shaders High, Tessellation Moderate, 16xAF, 4xAA, Full screen
Results: 3 loops successful with no problem whatsoever

Still don't have time to run more tests with games yet, will get on that eventually...probably will have another quick run on BFBC2 sometime tommorrow (since I'll be out most of the day today)

What games have you played with the above OC and for how long!?

Haven't got round to test with games yet, will do it later. Heaven Benchmark would stress the GPU at 100% usage throughout the bench, so I tends to use it for testing overclock, as it would crash very fast if unstable.

Quick question, using MSI Afterburner to control the fan speeds, but it won't go above 775/1125 out of the box. Is there a mod or something to allow higher speeds?

Running two of these now in Crossfire, so I probably dont need the overclock, but its always nice to know what can be achieved!

same problem for me but just with a single card.

removed previous ati drivers - rebooted - closed down - put new card in - installed new upto date ccc drivers - installed afterburner wont go above 775/1125

I would have thought MSI would have lifted the overdirve limits, guess not? you would have to use the afterburner unofficial overclocking method do breach the overdrive limits. I take it you're using the latest afterburner.

 

[MeMeMeMe]

in the other thread, danceforfreedom had the solution:

In the MSI Afterburner install directory theres a file called...

MSIAfterburner.cfg

You need to open this in notepad and towards the bottom you will see this...

EnableUnofficialOverclocking = 0

Change the 0 to a 1 and save the file (make sure it saves with the same name as a .cfg file).

Do this with afterburner closed and next time you open it you will see you can overclock it beyond the limits it had before!

 

[RavenXXX2]

Yeah it's a shame you have to use that method, I thought MSI would have set much high overdrive clocks as Asus does.

The cards run a lot cooler than my 4890 average 60c
Card 1: 47c
Card2: 33c
I expect these to get warmer as I’ve just had a quick look at BFBC2. Ok off to play some more.
Well impressed. Thank you OcUK for getting these out today.
Well after playing for a few hours without any problems, apart from the odd bit of lag.

Temps of 64c and 50c so i'm happy with that. Installed msi afterburner no overclock as I'm happy with stock for now. Just used it to create a custom fan profile so it runs a bit quieter during 2d apps.

Very happy with my purchase.

I'm happy for you but at the same time I'd love to give you a snow bath due to not receiving my card due to the stinkin' snow!!!!!. Stuck at hub 3 .

Sounds like a great upgrade. Now get off the forums and give your eyes some candy .

Merry Christmas one and all.

Impressive results already, great news

MERRY CHRISTMAS!

I thought I'd post my thoughts of using two of these in CF compared to a single Sapphire 5850 (soon to feature on the MM!).

These cards run at a higher indicated temp than the Sapphire; 80deg under FurMark versus 73deg for the same clock speeds 775/1125. I'm not really in it for huge overclocks so that doesnt bother me to be honest.

I've got the following framerate improvements so far, using 4xAA and 16xAF in each case.

AvP Benchmark 48fps -> 86fps
Crysis Benchmark 28fps -> 47 fps
Just Cause 2
Desert Sunrise 60fps -> 100fps
Conc Jungle 35fps -> 59fps
Unigine Benchmark
MIN 12.8fps -> 17.6fps
AVG 23.0fps -> 40.2fps
MAX 44.5fps -> 77.5fps

So all in all, very good scaling in those titles of between 50% and 85%. I have had micro stuttering in Overlord, but unlocking vsync seems to have resolved that; the game appears to be locked at 120fps max so it's not really an issue; but usually I am a VSYNC whore.

Power usage under stress has shot up from 250w to around 430w. Using Afterburner with the registry tweak to allow dual fan control I have the fans totally silent at the desktop and up to around 40% max under stress which is not much noisier than my Sapphire.

any one got a good stable OC for the r5850 using afterburner?

850-900MHz core clock should be done easy enough on voltage 1.200. I'm still playing with trying to clock it at above 900MHz stable with higher voltage.

 

[Monster ninja]

my card with afterburner keeps turning down the clocks.... what the hell

EDIT: for some reason i got to reboot to gt afterburner at apply changes

Edit 2: no it keeps changing the clocks to its stock setting! for some reason when ever i enable changes the core voltage it wipes any other clock changes and will not let you set new ones...

Nice to see this thread.

My card wont be delivered untill the 30th till then i can read this thread to get help/tips to overclock the card.
Should be an excellent upgrade from my ati4850.

 

[Monster ninja]

stable with no voltage changes(cant change the voltage when i do it resets clocks to "stock setting"

Core clock: 800MHz
Memory Clock: 1100MHz
Voltage: 1.09V(my cards stock)
Max Temp: 63C
Driver: 10.12

(works fine how ever drives crash in youtube!!!!!!!! even after a 3hour stress test?????)


i am aiming for volage (1.225V/ 925MHz Core/1175MHz RAM)
when ever i turn off my pc msi afterburner resets its clock...

here are the specs of a asus (i think?) HD5850 a out the box overclocked card
HD 5850 (OC+1.225V) = 925MHz Core / 1175MHz RAM


Here: is a good guide for overclocking a HD5850 http://tech.icrontic.com/articles/overclocking-the-radeon-hd-5850/ it might be worth a quick look
i am trying for the time being to aim for this

Just to check the order of how you save your profile...the following should be the order or how you should do it:

1. You entered the desired values
2. Press 'Apply'
3. Press 'save'
4. Press 1 of the 5 profile slots

And to keep your overclock setting after rebooting the PC, make sure you press the "Apply overclocking at system startup" (it should light up with a green light in front of the sentence)

Next time your on youtube dont press play on the video's...

Right click on one and you will see an option for 'global settings'

You will see a tick box for 'hardware acceleration'... make sure this is unticked.

Restart your comp and you shouldn't have problems with flash video's!

After seeing Monster ninja's post about youtube crashing driver, I quicky went on youtube to see if I have the same problem...and indeed I did. Disabling the 'hardware acceleration' under settings (not global settings) by right-clicking the youtube video and rebooting the PC, now the problem is gone. Thanks for the tip! It's good to see that this thread is actually useful for helping each other solving problems.

Oh and an updating on my overclocking. After crashes after crashes at the beginning of 1st mission on BFBC2, I've finally manage complete 1st mission and settle on a stable overclock of:
Voltage: 1.300
Core clock: 975MHz (1000MHz would crash in BFBC2)
Memory clock: 1100MHz (1125MHz memory clock would crash in BFBC2 with the core clock at 975MHz)

Memory clock 'can' go higher, but it will be at the cost needing to lower core clock if wanting a stable overclock; but as core clock has greater impact on frame rate than memory clock, I think it make more sense to use the current settings, instead of something like core 900MHz and Memory 1300MHz.

My suggestion for overclocking is to leave the memory clock at stock, and try to clock the core clock as high as possible as 1st priority. Then after finding a stable core clock, work the memory clock up (or down) starting from 1100MHz.

Another reminder is that for my MSI 5850 Twin FrozeR, it would crash in under 10 seconds into Heaven Benchmark 2.1 at core 950MHz if only using voltage 1.250mv; voltage 1.300mv on the other hand allows me to run through 3 loops of Heaven Benchmark 2.1 on core clock 1000MHz and memory clock 1300MHz on settings of Directx11, Shaders High, Tessellation Moderate, 16xAF, 4xAA, Full screen.

I think I will stick with the current core 975MHz/memory 1100MHz...and keep gaming a bit to see if I get an crashes.
