Hi I have a Sapphire 5850 I want it to flash which is flash BIOS of Asus and Msi? Some say if flashnal successfully thanks.

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.

http://farm3.static.flickr.com/2802/4214490452_575e5743f5_b.jpg

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?

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 .

If you mean this new ATI 5870 bios (http://www.techpowerup.com/vgabios/61848/ATI.HD5870.1024.091112.html), 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? :down:

nickless

01-10-2010, 09:15 AM

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.

Asus HD 5870 1024 MB BIOS only?

Someone, please.. :up:
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.

i am sure you can get your card running @ 1ghz, you mught just need more vcore but most 5850 and 5870 can do it. Maybe also a suicide(depending on what voltage it need for 4.5ghz) run at 4.5ghz for your 920 could help also.

Mine Sapphire HD5850 works very well up to 1000-1200 @ 1,2v with Asus 5850 Bios watercooled and catalyst 9.11, 9.12 and 9.12 hotfix.

When i try 1050-1200 even with 1,4v or 1,45v it completes all Vantage tests: GPU, CPU and Features, but in the end when it should show the score the PC hangs in a black screen and only reset solve it, this happens every time.

Strange thing is that it completes all tests without a problem, the problem is to show the score with a hanging black screen.

Can anyone help me?

Could you please link me to the stabliest and more overclocker bios?
Some say MSI bios is better, but in my case i think it's worse.

My goal is to reach at least 1050-1200 vantage tests completing score, once it runs all.

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

I went using msi AB but the core clocks never change to the setting on the slider when i hit apply.. the mem, fans, voltage all change except core clock. wtf?
************

HA! Missed this one!

@Dan7777 if you use msi afterburner you can go in the config file and change the value of enableunofficialoverclocking from 0 to 1 and it will let you go for more than the 960 core 1445 1175v limit of your bios and it with work with every card.

Ambient temp during that run was about 60F. The case I use is strictly for performance so its very loud, :) I used 1.26 volts for that run, card idles around 26C. I run 950/1100 for gaming at 1.12 volts

I use Asus 5850 bios, but this frequencies are not stable for gaming. For gaming I set the card 1030/1200 - 1.26v, but for this bench is 1.5v (but water cooled (http://img191.imageshack.us/img191/4673/pc202413.jpg)) with Smart doctor utility:D.

Wanted to clarify something real quick, I have flashed bios's before...just want to be sure I have it right.

I'm running crossfire 5870 cards, SO:

Uninstall video card driver & CCC before all of this?

Ok, Use GPUZ to make a backup copy of your current BIOS & SAVE IT.

FLASHING:
Plug in a USB drive to use, install & run HP USB disk Storage Format tool.

Select the USB drive, in the "file system" drop down box, pick FAT32.
Click "Quick Format". Click "Create a DOS startup Disk, using DOS system files

located at and click the "...." and direct it to the BOOTFILES folder (Boot Files

HP).

Click START.

Once done, copy the ATI Flash & ASUS BIOS onto the USB Flash Drive.

Restart the PC & Boot from the Flash Drive.

Once Booted,

Since I'm running crossfire, type in:

atiflash -i

This will tell ID# for each card.
one being 0 and the other being 1 (depends on slot number or just amount of cards installed?)

THEN, type:

atiflash -p -f 0 bios.rom

Reboot at this point with only the 1st card flashed? and then flash the next card?? or flash both at same time??

ALSO, I noticed in a NON-CROSSFIRE post (First link to flashing) that instead of -p -f it is -f -p ..... does this make a difference?
IS the -p -f order important? Is the -p -f the correct order for crossfire?

(Sorry for all the questions....don't want to fubar it)

zalbard

01-26-2010, 06:07 AM

You got everything right! :up:
And the order of parameters does not matter afaik.
Also some people flash their cards in CF one by one removing them from the system, but it is not necessary.

ZL1Killa

01-26-2010, 08:19 AM

SWEEET. now if I can just do it right....LOL.

So flash one card, reboot back into the USB stick, flash the other, reboot into windows & re-install everything?

Here's my personal best so far with my 5870. I haven't hit a wall yet on core or memory so I will keep pushing. I am currently running a stock card with stock bios and stock cooling.

XFX 5870 1GB XXX Edition - Stock Cooling
Core i7 920 Batch #3913A330 - Water Cooled
P6T Deluxe V2 ~ Bios 0006
Kingston HyperX 2000Mhz CL8 3x2GB Elpida Hyper
Corsair TX850 PSU

I am only using MSI Afterburner for both voltage adjustment and overclocking.

Will keeping pushing. Looking to get a nice full cover block for this card once I max out my clocks on air. A nice cpu with a higher multi would be nice as well. This Board has a bclk wall around 218.

Strange stuff. I can't seem to adjust vcore anymore now that I'm on 10.1. The option is grayed out in Afterburner.

Anyhow, if I don't touch the voltage I'm apparently stable to at least 800/1150 on this 5850. My previous results of crashing instantly at 850 using even 1.25V seem odd now. Any ideas what might be going wacky? I'm also miffed why I can't get to at least 1250 memory at default voltage when that's the stock rating for these memory chips.

This thread has been very helpful. I'm a noob at OC on vidcards. I've never flashed a bios, or done anything aside from running the auto tune in the ATI overdirve software. I have a saphire 5850 and I've downloaded MSI afterburner. Could you guys recommend a solid oc setting for my card? Currently it's set to 725 core and 1000 mem. I guess the fastest the current bios will let me set it is 775 core 1125 mem? I plan to utilize the stock cooler.

Flashing the bios scares the crap out of me. :eek: I've never done it before. I need to look for a good walk through on it. Any information would be helpful cuz i'm clueless...:shrug: Thanks.

5850 at 1000/1250 and 1312 core voltage
cpu reports as 3.6GHz but its really at 3.2... for some reason it wont accept anything less than max multiplier in vantage... oh well.

*edit*
so apparently Modern Warfare 2 was more of a challenge than Vantage was... had zero issues in Vantage but MW2 locked up as if there wasnt enough volts as it did in vantage before i jacked up the volts... already pushing 1.3+ into it.

Hey guys, I need some help.

I recently bought a 1080p monitor, and as nice as it is, my 4850 really struggles with every game I put at it, except for CSS or TF2. Now my questions..

1) Will a 5850/5870 bottleneck my E8400 4250Mhz?
2) Would it be worth upgrading to an i7 920 ontop of that, and ocing that to 4.0 GHZ...will that give me a decent FPS boost when paired with a 5850/5870 when compared my current overclocked CPU? What I mean is

E8400 4.25 ghz + 5850/5870
Versus
i7 920 4.0 ghz + 5850/5870 = How much more of a boost?

3) I hear you can OC a 5850 to 5870 speeds, so would it be better just to buy a 5850 and OC it to kind of get near 5870 speeds?
4) How about 5870 overclocking? Would it be worth more to buy that for 100 bucks more and oc that instead?

Thanks.

No point to go i7 imo, you can try and push your CPU a bit higher, though, and that'll be plenty.

02-06-2010, 03:24 PM

@dark-energy: is that 4850 512mb version? what are these "other" games? and are you trying to run at ultra high settings and ultra AA settings? imo no point investing in i7. and 5850 oc to 5870 speeds pretty easily... though i think it's the extra vram gonna make you feel a playable difference.

@frogeye: just use atiflash and save your original bios, mod it with RBE v1.24, save new one, flash card(s).

my question: i've seen some people with ridiculous high mem clocks like >1300. is that reasonable to expect? on my cards i'm thinking it's the mem clocks that it's not liking. i've bumped core volts up and i can get core up to 950 at 1.2v (could probably go lower volts) but the mem doesn't seem to like going above 1225ish before crapping out.

Just played Crysis Warhead for 20 minutes @ 950/1300 with the stock cooler at the stock fan speed at stock volts. Seems to clock quite nicely, way better than my other POS 5870 which needs 1.2v to be stable at stock clocks (LOL!). I didn't want to be without a working computer, so I ordered another one :p Once the faulty 5870 comes back from RMA I'll run them in crossfire :D Will see if I can get it 1000/1300 game stable tomorrow.

From what I know, for 5850's the voltage editing does work, but you absolutelly should not edit the voltages in "Clock info XX" columns. Use the "GPU registers" button and only edit voltages there. And I am not sure if 5700's are supported at all.

iirc you can set any voltage, theres a thread about it on here in this section...i'm still abroad and havnt used the latest version yet, i expect its just the same procedure as in previous versions. save your bios, open it in rbe, edit voltage registers and set clocks and overdrive limits+fan control... save and flash....

What is a safe temperature for both the VDDCs and the GPU? I'm running my 5850 stock 725 core 1000 mhz mem. But for gaming, I'll turn it up to 870 core 1080 mem with @ max voltage of 1.1000

This was FURMARK TEMPS
The gpu maxed out @ 83c
vddc1 max 92c
vddc2 max 94c
vddc3 max 91c
Furmark stability test is hardcore!

In Game BFBC2 1680X1050 graphics on high settings
GPU max 41c

vddc1 max 39c
vddc2 max 39c
vddc3 max 39c

I would imagine that I could OC some more for games.

I'd like to revisit using RBE to modify core voltages. Do you edit register 0x17 and then use the number you put in there as well for the core state voltages? Alternatively, do I leave the core state voltages clear or use the value corresponding to the default voltage of that register, etc? When I tried modifying the voltage on my 5850, it didn't work.

Don't use that.
Use MSI Afterburner instead.

@ Frogeye: ramp up the fan for furmark, can leave it on auto when gaming, and push the card higher.

I just got two Asus 5850’s a couple of weeks ago from Newegg, the default settings are 850/1200 and the BIOS appears to be the same version as the 5870 according to GPU-Z. Also Asus Smart doctor doesn’t recognize the cards which may indicate they have the 5870 BIOS. Has anyone else seen this with new out of the box cards?

Yeah I got one of these from Newegg and I thought the card was flashed with a 5870 bios and returned so I sent it back. My buddy got one right after and he had the same thing so it looks like they are coming from the factory flashed like that. The second one I got after the rma was normal 725 clock.

Using upto 1.3v using MSI software did not help at all...could it be that the voltage is locked? Which is the best bios to use now.

Also has anyone changed the TIM on these things...any reason to do so?

from what I hear the newer revision Sapphire 5800 cards have no voltage adjustment, but if you can access the voltage slider in AB chances are it's the older revision. The ones that I've tested that were the second spin, AB blacked out the slider.

I've got a Visiontek 5850 I just bought to replace my 4870x2. So far I've loved the thing. However, I'm not as satisfied with its overclock as I could be. I get 960/1250 stable at 1.27V in all games and benchmarks, but at 1000 core no matter what voltage (up to 1.35) my card is unstable in L4D. I can run Vantage, heaven, furmark, but anything around 1050 is unstable even with stock memory and voltage set to 1.35.

It seems like I've just got a weak GPU, with 1.27 volts max gpu core is 960 whereas I see others doing 1050 at 1.27. I'm thinking about flashing another bios on the card and seeing if there is a difference in what I can max out.

I also find it odd that I can get L4D to crash my 5850 when no other game/benchmark I run ( I played bfbc2, supreme commander 2, anno 1404, dirt 2) each for about 2 hours and never had a crash at 1000. Yet 1000 on L4D crashes with artifacts after about 8min. I noticed someone else on XS said the same thing about their 5850 and L4D2.

Has anyone noticed that more voltage actually had a significantly detrimental effect on their overclock of HD 5850? For example...

1.125V/900/1250 - stable
1.137V/900/1250 - slight artifacting
1.149V/900/1250 - significant artifacting but then...

1.187V/975/1250 - no artifacting, stable

It's like the voltage has to scale with clock speed, i.e., pumping even slightly more volts at certain clock actually has a negative effect and makes the card more unstable. This is not a one off thing, I can pretty much produce it at will.

I might test out that theory with the Asus HD 5870 actually. Something similar was puzzling me about it, at times it was stable at a certain clock but at other times it would just artifact like mad so maybe the vGPU I was using might be causing it. I'll check that out over the weekend.

Yeah, it would definitely be interesting to know. I know that 5870 vs 5850 is a bit of an apples to oranges, maybe more like granny smith to red delicious :p:

Anyway, I'm pretty sure this is not a fluke but a lot of people don't look at this kind of stuff. It is puzzling though as it definitely behaves as though voltage scales with core clock and more volts is certainly not always better despite the cooling. It's like the cards have certain voltage "sweet spots" for a given clock. I'm still waiting on my second HD 5850 to test this theory out on as well.

That'd be perfect for just about every overclocker with a 5850 that isn't satisfied with his clock speeds. However I am pretty skeptical of it. I guess there could be some interference except at certain voltages, but that's far stretched I think. I'm going to test this idea with my visiontek 5850.

I've been hoping for 1050/1300 stable but I can only manage 960/1250, not a big difference but still.

:confused: Not sure how this would be perfect for people overclocking... :shrug:

Anyway, I did some more tests and definitely my card behaves this way. I tested 1000MHz core at 1.225V and then at 1.237V and while there were no artifacts at 1.225V at 1.237V the artifacts started within the first 2 minutes of test. Then I increased the core frequency to 1005MHz and I managed to go 10 minutes without artifacts. Then I increased to 1010MHz and I went 20 minutes without artifacts.

So very, very strange. It could be some unbelievably weird coincidence that I keep on hitting every time, but I doubt it. It's not the first time I was able to reproduce this either.

you running furmark for your tests?

03-02-2010, 03:02 PM

you running furmark for your tests?

Running Furmark 1.8.0, ATITool 0.27 beta 4, and Kombustor for general stability tests, then Crysis Benchmark, 3DM06 and Vantage for gaming stability. Basically the whole suite. I observed the same type of behavior with each tool.

Edit: I don't necessarily see this as a problem, just as an interesting quirk. I just did ~1h of ATITool with no artifacts at 1.225V and 1000/1250, bump to the voltage and artifacts start right away, bump down and artifact disappear. In Kombustor this instability will show as flickering of the MSI fur generally, sometimes actual blocks will appear.

i have some noob questions:

- can i use any [reference] brand bios on my Visiontek 5850? i have the Asus bios on there now, but what if I use MSI, in order to be able to use Afterburner (and will I be able to?)? i know the safe answer is just to modify the Asus bios i already have on it... since it already works and is already unlocked (unlike the Visiontek)... but if the MSI is the same as all the others but has Afterburner, mind as well...
- i do not have any 'selectable voltages' in RBE. do i just type in the voltage i want for the main/high/3D clock section ("Clock info 00") and leave everything else the way it is if i do not want to mess with 2D and such clocks?
- if i someday figure out my exact desired overclock, can i just put it in the Clock info 00 spot directly... and never have to even use catalyst control center? since it is in the BIOS, i wouldn't need to install CCC to see working powerplay and overclock?

1) yes, but afterburner works on any 5850
2) input vgpu into gpu register box, DO NOT change in the clock boxes or in the overclock wizard dialog box. You'll break powerplay if you do.
3) use the clock wizard rather than editing the boxes directly.
afterburner wont let me edit voltage on my card... i thought that was because it wasnt MSI. i guess i will stick with Asus. but it doesnt matter, right?

ok found GPU registers now, makes sense, i just got worried when i didnt see the list. so i just replace the other normal-high voltage (0x17) (1.087v) with what i want (1.175v)?
when i do that, even after saving the bios, i notice this does not update the voltage listed in Clock info 00, 01, etc... this is normal? the new voltage i put in 0x17 will take command?

...so no real way to use this to get rid of having CCC control powerplay?
if i cant get rid of CCC and still use powerplay, i mind as well just do the overclocking within CCC for safety.

thanks!

Does anyone have a modified 5850 bios thats stable with GPU core @ 900mhz?

Scares me because I wanted to get another 5850 at some point but it looks like I'll have to stick at the common denominator of 950/1200 even if the new card does 1050/1300.... blah...

Hey guys just thought I'd share my oc'ing experiences with 5850 CF

using Afterburner I managed to get both cards upto 945/1200 @ 1.22v but dropped them back to 925/1200, everything seemed fine, vantage ran np, crysis, bad company 2 etc etc all run great, except I noticed in N:Total War that I get severe microstuttering, when I drop the clocks back to 775/1125 (CCC limit) there is no more microstuttering..
I think the Over Current protection is kicking in and tbh I suspect that a lot of people that think they have these insanely high oc's are infact getting errors but just dont know it, its very hard to tell apart from a little stutter here and there or lower performance..

So I'm a little confused, should I drop my oc because of that one title, which probably proves that my oc was never infact stable, or becasue everything else seems to run fine I should leave it.. but then again how will I know if Im getting true performance in game or if there happens to be a little stutter that it isnt caused by Over Current Protection?

What is considered as max "safe" 24/7 voltage for 5870?
Cooling is not an issue, 34c in furmark at 1,2v 1ghz.

Is 1,35v okay? Perhaps even 1,4v?

Zeus

03-15-2010, 05:41 AM

There's no such thing as a safe voltage other than stock voltage. Go as high as you dare or as high as you think temps are ok.

For 24/7 usage i would just use stock voltage, only for benching i'd go higher. As high as my cooling can take and as long as there is still scaling with voltage.

bhavv

03-15-2010, 06:07 AM

I think up to 1.35v is fine as long as the temperatures dont go to high, and since overclocking software supports up to that voltage.

The gains over 1 Ghz arent usually worth the extra required voltage, eg my cards manage 1000 Mhz @ 1.225v, but to get up to 1050 Mhz artifact free, I need to push the voltage to over 1.3v and keep the temperatures under 75 degrees.

I would only go higher for benchmark runs, but for 24/7 use, stick to around 1.2v and 1000 Mhz. I suggest keeping the temperature below 85 degrees.

Any idea why my VRM temps would be so high? Also the GPU is getting up there at 53C. Maybe I didnt tighten the block down hard enough.

Are you using the thermal pads and the standoffs? I read in the EK thread that VRM temps should be better running without the pads.

Hi guys
I'am having trouble with Afterburner and vista-64 bit. After i edit the file that enableenofficialoverclocking from 0 to a 1 .Then try to do a over clock in afterburner it crash my pc every time . Got any ideas ? or i'am just a dum ass.:shrug:

I got that and after some googling i found a solution. Right click the msi afterburner.exe and choose it to run as "Windows Xp SP 3" compatibility. Solved it for me.

However that dident solve my problem :p The thing is i have the well known flickering-when-more-than-one-screen and i tried to solve this by modifiying my asus bios and lower powerplay and standard clock to 550 / 900 ( I get some minor flickering when i leave standard clock at 725 / 1000 ) But when i do this my maximum overclocking capability decreases to 825 instead of 1090. Tried reflashing serveral times but i cant seem to find a solution to this. Any tips?

( I use the Unlocked Asus bios as base. Dont know if it matters but i have two 5850 in crossfire. )

It was MSI's decision to limit AB to 1.35V, just to prevent a rain of rma'd cards.

And they did it for a good reason. Stock cooling don't have much headroom for overclocking in high ambient temps and a overvolted card can be easily overheated.

...
Havent tried more than 1.35 as thats what MSI Afterburner allows and I cant push Core past 1045 so I need more juice temps not high anyway wiht 100% fanspeed and extra fan at exaust and intake...

Unless you are living in arctic igloo voltages above 1.35V will fry your GPU. So, just to be on the safe side consider buying high performance water-cooling like Zeus did.

A little bit of CrossFireX action with the second HD5850 on air (one is on water already, the other is on air, just arrived) :p: :up: Yes, these are Furmark stable clocks on GPU and LinX stable clocks on CPU ;) No, this is not the highest that it will go. I will have higher scores once the second water block is installed on the new HD5850 in a few days.

Do you want me to overclock the 5870 and/or CPU? What CPU did you use and what speed? I have an i3 CPU and 980x so can use either.

1)I'm planning on Overclocking my future HD5870 Powercolor reference card (Haven't arrived yet) and my plan is to flash Asus bios and tweak the voltage and OC the card to 1100/1250. is it possible to do this on stock cooler?

2)But, is flashing Asus Bios is a real Hassle? Or is it just an easy task? Sorry haven't tried flashing GPU bios before.

3)I've heard of cards died by tweaking voltage and all, but is it possible to flash back the original Bios after the card died?

4)Or are there any possible situation that will fail me to flash the original Bios back?

Thanks in advance.

1) 1100 is far too ambitious, shoot for 1000 core.

2) It's easy, just google for a flashing guide.

3) Not possible to flash a dead card, period. Cooling is everything in overclocking/overvolting, just use common sense and watch temps.

4) None that i could think of.

Now, that's fast. Thanks Zeus. Anyway, I have the budget to buy 5850 or 5870, but I read a lot of reviews that 5850 is not very far behind from 5870, but there's no decent reviews in term of Oc headroom.

1) So, I wonder can HD5850 do 1000/1200, currently trying to read the thread from 1st page to the end but I've yet to meet anybody done my preferable clock on HD5850. (If it's possible might as well go for HD5850)

2)So I guess investing on Artic cooler Twin Turbo for this card is not bad idea after all~ Hope I can achieve 1000/1250 on Hd5870+artic cooler twin turbo with minimal voltage increment.

Do anyone get any flashing artifacts sparkles in the beginning in Crysis, where you land the water without the airsuit? Near the beach, I see flashing artifacts only on the trees, they are little above your ground level.

Anyone with overclocked 5xxx, please try and see if you see any artifacts because I had the same problem with 4870x2 and 4890. :down:

If anyone wan to detect if they have artifact, please crank up all your setting( 8x AA ect), go to the beach I described and gloom over the trees for a minute.

Edit: Same problem with stock clock.

I have tested both the HD5850 and HD5870 at 1000/1250 and i could barley notice any difference in performance , Stalker had like 10% advantage with the HD5870 , otherwise there is like 5% difference across the board for 30-40% more $$$$

What's the voltage for both HD5850 and 5870 probably the former should be pumped a bit higher, yes?

If both done in stock HSF I might go for HD5850 but need to know the voltage 1st since have to worry bout the electricity bill :P

Both are done on stock HSF with fan at 60%
Amount of Voltage will vary from card to another , my 5870 sucks and needs 1.32V to be 24/7 stable for games but it fails at Furmark with that Voltage , the HD5850 only needed 1.27V but your milestone may vary

I noticed my 5870 does love the cold. I recently hooked my rig up to a custom waterchiller, and with around 8C water I got this:

http://hwbot.org/community/submission/983498_jcool_3dmark_vantage___performance_radeon_h d_5870_26123_marks

Using around 1,4V VGPU it's Vantage stable at 1150/1350... around 1130 is the max I can get through FURmark. Pretty impressive considering I couldn't go past 1070 on straight water.
I would have loved to see 1200, but I fear that's out of reach without the use of DICE or LN2.

Also, a question:

What bios do people use on ref. design HD5870 cards these days?
I am still on the first unlocked Asus bios, but for some reason setting VGPU in bios never worked for me.. even more, my card was re-set to 1,12V VGPU (so lower than stock) and I couldn't for the life of me fix it. I even flashed some modded bioses from other users to make sure it wasn't my fault, all to no avail.
So I gave up and just used Afterburner to set my clocks and Voltage..

But now, I'm willing to try again :D
So what's the latest Bios with at least 1200/1400 clock limits? Thanks :)

madriddistas

04-04-2010, 03:20 PM

Wow Kemo, I read that article and that was Hell of a Power Consumption. Hurm.. I think it depends on luck whether to choose a better overclocking card but it's safer to choose HD5870 since a lot of that card can clock 1000/1250 with lower vcore and I got it from a few pages back from this same thread~

@jcool, 1.4 dude, that's impressive clocking but I'm not a fan of high Voltage clocking for GPU but good luck trying 1200/1400. Do post the result here. Thanks~

jcool

04-04-2010, 03:37 PM

Thanks, I figured 1,4V was safe since the GPU temps stayed below 20C at all times (VRMs topped out at ~45 during Vantage runs).

I now flashed some MSI OC bios dated March 2010, this one (http://www.techpowerup.com/vgabios/70100/MSI.HD5870.1024.100305.html).
Flash was successful, it reads 2000/2000 as CCC limits and powerplay still works fine with OC.
However, my old problem persists - stock VGPU at bootup is still 1.125V instead of 1.1625V :shakes:
Also, when running a GPU DC app like Milkyway OR running Furmark in windowed mode, the mem voltage stays at 0.95V. Only when entering fullscreen 3D does it raise to the proper 1.15V - memory clocks do rise, however.
This behaviour is strange, and does not occur with the old Asus OC bios.

Guess I'm going back to the old one then :shrug:

The mystery revolving around my stock VGPU remains unsolved :rolleyes:

jcool

04-04-2010, 03:49 PM

..and back to the old Asus OC bios. This time, I edited it using RBE 1.25 - I changed the VGPU register to 1,175V (obviously that didn't work, still 1.125V load :p: ) and the VTT register to 1.25V (that one worked - maybe it'll help me get to 1200 core?).
I also changed the default Core speed to 900 (check). I didn't change overdrive limits. Note how this bios ramps up the VDDCI when running Milkyway@Home (BOINC) - so it's obviously more intelligent than the MSI bios :p:

Anyone who can solve my VGPU mystery - I'm putting up 10 bucks as a reward if you can figure it out, cause I'm all out of ideas here. :shrug:
