4890 OC limit fixed!

[SF3D]

Hi all!

THERE WILL BE NO DOWNLOAD LINKS AT THIS POINT AND PLEASE DO NOT PM ME ABOUT THIS :cool: (This should not be offending, if someone find it that way)

We have been doing some work to solve the problem in 4890 overclocking. We all have seen this issue, when we have tried to push our 4890 cards higher.

We got new bios with requested fixes to test few days a go and I decided to try it out today with my dual head CF/SLI single stage.

Temperatures were like under -30C on load and -40c on idle, so much more is coming when I will put these cards under LN2 :up:

I have no info when this bios will be officially released, but it will happen sooner or later.

See the results yourself:

Single card fillrate 1225MHz:

http://www.aijaa.com/img/b/00046/4425861.jpg (http://www.aijaa.com/v.php?i=4425861.jpg)

Then I installed second 4890 in to the setup. This card is ES and it is not good clocker. (1030 on air)

Results:

Dual card fillrate 1200MHz

http://www.aijaa.com/img/b/00823/4425883.jpg (http://www.aijaa.com/v.php?i=4425883.jpg)

I will get some better 4890 cards tomorrow and I will try to do some 05 and 06 scores with them. Let's hope, that the 975 will do at least 5.3GHz in 05 :(

I'm satisfied if these cards will do at least 1.3GHz on LN2 :D

Bench day will be thursday and hopefully my lucky mascot Massman will be helping me in here.

[ceemic]

SF3D, tnx for the info :)
But what Vgpu were You running?

[G.Foyle]

Argh, beat me by 101 pts in Vantage :D
I dunno how but I benched 1200/1200 on modded bios on dice with 1.425 V, without any problems :shrug:

[SF3D]

You are extremely lucky. I hope you did win in lottery too :)

Some cards can scale up on core speed with cold, but it is very rare. Most cards did not do much over 1100MHz on LN2, so this is the issue we are talking here.

To ceemic. Better card 1.365V and worse card 1.4125V

[HousERaT]

looks interesting.

[SNiiPE_DoGG]

So I get the part about not releasing, but can you give some insight into the BIOS modification? I have heard that there is encryption that needs to be broken for proper unlock and other major changes to a bios and that BIOSes dont even work cross AIB in some cases.

[TiTON]

hmm.. very interesting.. So it wasn't my imagination that I couldn't get over 1100Mhz :) That is good to know. Now to wait for the BIOS to be available :)

[chew*]

Interesting but I've known all along that software was not the way to clock these cards......bios fights with it..........so I hacked the hell out of my bios :D

That bios looks a tad better than my hack job however :)

[N3RO]

Sounds interesting :)

Lets see 130k+ on 2001 with ATI now :D

[SF3D]

Why this thread is moved to 3DMark info and support? The word info in the start does not mean that this is not Xtreme overclocking?

There was already two 4890 single card records in this thread and more is coming :up:

Please kind moderator, move this back to the Xtreme 3D where it was :shrug:

brandybuck,

I have sapphires also.. i need to check which bios version I have :)

Were those stock bios.. or did you tweak them?

[Movieman]

Moved here on request of the OP..

[SF3D]

Brandy- What was the temperature and model of the card? Stock bios without mods and what was the core voltage?

This thread is not about these rare LN2 clocks. If 100/100 cards would do 1200MHz on LN2 out of the box, then this thread would be worthless :D

When this bios will be in public use, we will see some sick overclokcs for sure.

I run -120C 1.48v with this speed:)

[Hazzan]

Nice info and sharing....:up::up: so for now we just wait officila bios realised and see for your test :):)

[G H Z]

Looks good SF! Running over 1200/1200 in CF is not easy with these cards :clap:

[purecain]

new bios coming.... hmmm very good news... good luck with the ln2 bench SF3D......

[ILikeCosmosS]

looks great now i wonder if xfx cards will clock this far

[Vivi]

Now to wait for the BIOS to be available :)

look at 295 mod. it wont become avail to the public

great clocks sf3d :)

[TheKarmakazi]

very nice please let every1 know as soon as this bios is made public!

[TheKarmakazi]

Slightly different situation though Goddy. GTX295's VT1165 is a voltage reg protected by NDA for any pin out info etc. Anyone revealing it would stand to be sued by Volterra. And they do prosecute its happened before :up:

[illuminatiASUS]

Impressive numbers to say the least. In every sense of the word. Keep up the great work.

[jobol]

Will this new bios work with all 4890? or a brand/model in particular?

That is exactly the problem we are talking here ;) I think most of us have seen this behaviour with our cards. Some of the best ones can do 1070MHz-1100MHz without 3D load on air, but that is rare.

i benched in Xfire at 1090/1175 on water but i was disappointed going to SS phase with -50C on the core as it couldnt pass nature at 1150Mhz even >> is this what you are saying you fixed? cold scaling? with bios? did you fix the volt limit they have?

so whats the point of telling us about a it if you dont want to share the info.

Yeah.. you are the one who have been hitting your head in to the wall :D

Cold is not the problem with these cards and you can't fully fix this problem by cooling your card. Voltage is not the problem and voltage does not fix it either.

I see you dont have the clue what is the problem, so calm down :up:

Point of this thread, is that you can see what these cards can do under LN2 etc. This fix will be available for sure in some point. You just have to wait.

Yes I hit a clock wall after 1075 on air in vantage with every single card and I have a stack here......it can't be the cards.....and this is with a highly modded bios......so I must have missed something.. get a weird screen but its not artifacts....and it has an AMD logo when it happens.....

[dinos22]

so you didnt answer any of my questions :shrug:
you can say what you fixed without reveiling how you did it i guess but yeah it's your call

calm down??? i'm calm :shrug:

when it first happened I was like wtf......Maybe I tinkered with bios just a tad to much....05 and 03 run higher than 1075 :D

[crustytheclown]

Sorry but i can run both my cards 1230Mhz core with just dice and softmod, and here is proof (from low clock challenge)

http://www.thelab.gr/picture.php?albumid=142&pictureid=2318

The only think i had to do is fix the 2d and 3d mode to stable Mhz for both (lets say 900/1100) and the same goes for voltages.(1.31v 2d-3d).Thats why some cards refuse to go higher...they just jump from 3d to 2d mode (especialy in 3dmark03-05 and for no obvious reason).With this hint you don't have to care about that...

ps i use atitool to clock both cards that high...
i have other benches too!!!

[dinos22]

lol thats pretty good crusty :up:
thanks for sharing

[cowie]

great crusty i will try that.
over the weekend i had my card at -20 and all it ran was 1100 from 1066 on air to say the least i was pretty pissed and flustered.
as for sf3d holding...how many times as he helped us all with mods so i'd sit tight.
hes very shareing with this kinda stuff

[Oliver]

Thanks for posting SF3D , glad to see you guys & co got it all good

Absolutely true regarding there are some few cards pushing , my friends does 1325mhz GPU trough 2k5 on a SS (180 or 250w tuned unit)

what voltage did you ran 1066 at , 1.4375? and what would accour if you raise the speed from 1066 to 1067mhz GPU ?

[..::G80::..]

Mine 4890 did 1080MHz on deff cooler and volt was 1.45V.

[Mean Machine]

That would probably be the clock testing feature in CCC.

Yes. Most of the cards hit that 1070 limit on air. After that colorful screen etc. AMD logo is new thing to me.. that is quite nice feature :rofl:

Well, Brandybuck and Xogolatl can run their cards at 1200MHz too, so your cards are similar. Be happy with them, really :up:

That issue you decribed is not the one this new bios will fix. But there is a slight chance that they are connected.

Well.. partially wrong. Those cards which can do 1200+ already are very rare samples. Results with those cards are unpredictable :shocked:

This will be very nice for most of us with normal samples. We will benefit most about this fix.

All cards hit the (black screen) limit at 1070MHz on my room, which is almost +30c at the moment. After bios flash all cards were able to go over 1100MHz without load and around 1050MHz-1100MHz in 3D load :up:

ETA --> One week ;)

Maybe bottlenecked by the low HT link?

because im bad with that amd :(

[macci]

HT at 1.6G is plenty for a single card and 3DM05 GT3. Could be something else though in the OS / Driver settings.
Run the Multi-texturing fillrate test to see where your engine clock really is.

Glad this is coming from him and macci.

[dinos22]

ATI cards can be funny when pushed too hard or at the wrong clocks

but he very well may have a card that is capable of benching with stable 3D numbers past 1250 who knows heh

to be honest 1.4v was something i was told recently. i benched 4890s and have returned them since without checking with DMM but if it says 1.488v that should be pretty good for high LN2 clocks

Nope, but the program also reports the current voltage is 1.53v. I know it doesn't have to be reliable. Will do more testing next week, with DMM.

[runmc]

Brandy- What was the temperature and model of the card? Stock bios without mods and what was the core voltage?

This thread is not about these rare LN2 clocks. If 100/100 cards would do 1200MHz on LN2 out of the box, then this thread would be worthless :D

When this bios will be in public use, we will see some sick overclokcs for sure.

Do you have any news for us?? Updates please!! :D

Yah no problems with this bios toasting anything not that that bios your on did at least I hope it didn't.

I to have tested on a stack of cards.....other than the weird screen over 1065 core....no issues. Of course I have not played cold on them but I doubt it will make a diff.....I know there is a bug just haven't found it yet. The screen issue is funky to.....03 gives gray/darker gray lines......vantage is hilarious a colorful reddish/orange/pink screen with an AMD logo.

Software clock the cards easily higher.......however according to results well USE whats fast......not what you think is fast. Canyon points to the fact that software is not working.
Vantage screen stutters like crazy when loading using software.....scores lower......

This bios was done solely by me no outside help, It also only works on ref cards...

[[XC] gomeler]

These secret BIOS' hardly matter considering how much power there is in 4x HD4890 at 1GHz, let alone stock. This is like HD4870x2 CFX, you are already CPU bottlenecked at 850/950 and see scaling in only 03. Plus chew*, you need LHe to be competitive on AMD :D

What we need is another Vantage to even things out, Vantage sort of keeps scaling, especially High/Extreme, so where is 3DMark2010?

[chew*]

ehh scaling dies at 6.2 with 2 cards...till you increase clocks over 1000/1150....then they scale again.

As for Lhe...eh 6390 3d stable on ln2 nothing to cry about.....see If i can push the bar higher in the future.....

Railmeat,

most of the "guys" that you mention can "mod" bios's with RBE and what not...very true......but bad things can happen when you do a True bios Mod and start rewriting bios...Not to many people can do this or have the necessary "tools" or knowledge to do so.....nor can many break encryption....

Took me 3 weeks to crack certain things in the bios and still not perfect yet with the right tools.

This bios what I am talking here will have to be delayed a bit. Sorry!

We run out to some new issues under LN2. It was not the cold bug, cause there is no such thing. I could run Vantage at 1250MHz core speed, but other benchmarks was not ok at that speed. So we have something else holding us back. We are going to search the reason for this. If someone can modify bios just change SPLL_REF divider and you are good. This issue have haunted ATI cards since R600.

But for real Chew, it is time to show some results. You are just talking here, but if you did not change that value I am talking about, your bios will not do anything serious.

[dinos22]

i'm assuming that will not hinder the vRAM clocks as you scale up in MHz > SPLL_REF

About the same thing here. However, for me it also some strange behavior like that 3D06 passes @ 1065/1050 and 1065/1140, while Vantage fails @ 1065/1140 but works at 1065/1150 and 1065/1165 where 3D06 fails. 1065/1035 works for Vantage but i cannot make 3D06 pass that.

What fix are you talking about? 4870 did not suffer from SPLL_REF Divider issues.

[chew*]

What fix are you talking about? 4870 did not suffer from SPLL_REF Divider issues.

Exactly......besides core speeds/PWM whats the difference from a 4870 to a 4890........ram timings and clock speed of the same GDDR 5.

Why not try importing ram timings / speeds from 4870 and then try out those core clocks.....

[SF3D]

and... ?

*I am playing stupid here, cause you try to be mysterious.

[chew*]

I don't know how more clear I can be....I think the ram clocks and timings of the ram on the 4890 are hindering core clocking........Import the timings and clock speeds of ram from 4870's and give it another spin........

If you go BACK to the 1900XTXs, you'll see that NOTHING could overclock them from a certain CORE frequency and above....
ONLY an OLD modified atitool which changed its frequencies DIRECTLY inside its cores....
Not through software or anything like that.... :)

[hipro5]

I want to add something to this which perhaps may disappoint some of you and bring in an "uncomfortable situation" the ATI company/designers... :(

Those 4890s, DO NOT have a 5 phase VGPU design as the reviewers have told you and ATI DIDN'T EVEN mentioned that (by mistake? :rolleyes: ), BUT instead, it has ONLY THREE phases as for it's main core.

SO DON'T expect to overclock it ONLY with a bios fix (which personally I don't believe it'll help much or not at all).....
PLUS some/many/all of you may SEE frequencies going up as is, but the card works to the frequencies SHE WANTS and NOT as YOU have picked.... ;)
You NEED hardware mods to do so....

George, you don't need to make excuses or explain why you will mod the hell out of this card, just do it man :rofl:

So, basically what you are saying that regardless of software/bios fixes (if an when they will come at all), those cards doesn't have a lot of juice in them anyway due to lack of phases ?

There are 3 phases for the MAIN CORE
2 phases (NEXT to the 3 core phases - 1.2Volts) for another circuit inside the core (VTT?)
1 phase for the MAIN RAMS
1 phase for rams VTT
1.82Volts for the Core (VTT?)...

PLUS Rivatuner VT1165 can provide you UP TO 1.45Volts REAL....
EVEN if you pick 1.7Volts, it gives you 1.45Volts REAL and that's it...

TIP for guys under LN2
USE ONLY the 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, 1300 as for the core and ALSO every 50MHz as for the rams
The XTAL oscillator on these VGAs (and the 4870 series) it's NOT 27MHz so to go every 27MHz step...
It's 100MHz, so NOT to get into problems, follow the RULE every 50MHz step... :D

Those two phases are for memory controller in GPU. You need to raise that voltage as well, if you like to clock your memory well.

This bios does fix the limit, but it does not make any card to clock better. I think this is what people have missed in here.
Bios is from ATI engineers, so I am not talking crap here. We need to find the issue, which holds us back after 1250MHz clocks and no, it is not voltage.

Mod the card George, it will help for sure. Let's hope, that cores will scale well in your tests :up:

I already wrote long text, but my 3G connection faild in the summerplace and I lost the text.

I did some testing in the end of last week and did 03, 05 and vantage runs at 1250MHz and 1.45V (-60c) Cards are working fine until I hit 1200+ MHz.
With this "fix" bios there is no problems using different memory speed with some core MHz values etc. You just hit the limt of the chip very easily. There still might be some other limiting factors in bios and we will have to look them.

If for example Hipro will do some heavy hardware modifications or use vga maximizer, he will gain some MHz for sure. But using just stock card + software voltage control, it will not go that high on core speed as I hoped.

Well, all cards seems to be cold bug free, so temperature is not the problem.

Let's wait how high Hipro can push the card and then see what was the key thing for it :up:

Hello, thanks for sharing SF3D :)
You said all cards are coldbug free... so there is no gain from -60°C to -140°C with the same voltage?

If this is right, chip maxed out or there is another limitation in Bios... oh man... hard stuff...

All cards show the same behaviour?

[Revv23]

I'll make some test tommorrow because today I'm TOO busy with work.... :(

Maybe it's some kind of bug like the days of the 1900XTXs....I don't know... :confused:

Don't you know never to let work or family get in the way of your overclocking!

Go to a place with the software is requirements for high-speed hard mode.

Software mod gpu max 1300 mhz limits.
Hard Mode Gpu max 1300 / 1500 mhz + Fast.

when the bios becames pubblic?

If I'm reading him right ;) it won't ever be public. It would be interesting to know why AMD prefers not to release it.

Guys if this card has ONLY THREE phases and ~30A to 35 (even 40A) each, what do you expect to see?.....
EVEN if you mod it not to shut down from any kind of prOtection, the Mos-Fets of it CAN'T provide you THAT much POWER.... :D

Wait and see a 2k1 with them in CF powered by 2 of my VGA Maximizers.... ;)

[dinos22]

if these reference 4890s had a true 5-phase power cuircuit on GPU core it would easily hit past 1250 with more volts i'm sure

the 4870 Asus Matrix cards i have here with non-reference PCB and 4phase and custom software providing up to 1.6v on the core let me bench the cards in xfire past 1100MHz core....i can only imagine a similar PCB with 4890 silicone drooool hehehe

one of the cards packed it in but i did take a screen testing nature with single later......

Why you have to repeat this again and again? In the start you removed this thread and you have said at least 5 times, that I am talking BS here. I find it only funny.

This bios does fix some issues, but it does not make cards to overclock better. That have been said many times. If the core in some card is bad, it will be bad after flashing the fix bios. But if some card does have a good core, but it is limited by SPLL divider, this fix will give wings to those cards. Like in my case, one card gained almost 200MHz by the bios only.

I hope this bios will be released, so everyone can see this by themselves. Now everyone is just hoping that there is some miraculous HW mod, which will fix SPLL_REF divider issue. HW mods will fix the need of power, but in some cases that is not helping at all.

Tired of talking about this. Next time I will publish the bios or I will not say anything anymore. This is boring for me as well.

Perhaps someone who has the ear of the manufacturers might want to mention that a card which can support more power and a fixed bios would be a sure winner. Maybe like an ASUS TOP version or something. Just a thought.

Whatever it is there is no easy fix.....I tend to think its a combination.....

Anyway my bios will be up for release in the near future......I put the final touches on it today.......everything seems to be working across OS's ( although I have not tested 64 bit ), I had one person test it out on non ref and no luck....so ref based only.......

The above screenshot really doesn't address all issues.......however some of you may have run vantage in multicard.....with software the screen flickers at load.....scores don't seem to be on par etc etc......I found multicard brings out the worst in these cards, especially quadfire.....cards don't appear to run in sync, and you may have noticed taking a hit clock wise in multi card versus what the cards can do individually.

These issues are fixed. Other issues will be adressed later if physically possible. Final rev will have a core clock limit of 1065 until the issue is 100% truly fixed.

NO I know for a fact there were performace issues ;) I have screens of my own prior to this bios depicting the same results......poor performance per clock via software. software is battling the bios.....

I believe the best way to describe it is the cards are jumping from 3d to 2d mode but actually not the case. More so they are jumping back and forth from bios clocks to software clocks.....

Canyon is more so an indicator of this than cpu score, I just chose to use that result as an example......how about an AMD result?

Note canyon...http://www.xtremesystems.org/forums/showpost.php?p=3893633&postcount=1

Your fix notwithstanding, the scores you're showing don't have any relevance.

First of all, 33.5k is a very good score for 4875MHz on a Nehalem.

Second, at that level 06 is completely CPU bottlenecked. It is even for you as your own screenies show. Margin of error difference between 1000 and 1050.

You're comparing two wildly different setups in a completely CPU-bound test. The GPU's have nothing to do with this. On a Nehalem at that speed you'd barely lose anything even if you were to switch to two 4870X2's, or were to bring the 4890's back down to stock.

compare the amd system gautam post 186 ;)

Or just ask vince about austin.....scores weren't what they should have been which led me to investigate this in the first place.

Doesn't really matter to me if you think this works or not, I have my own results here and have been compiling results for a few months now.

FYI margin of error is in my 1000/1050 results favor due to cpu score.

What it namely adresses is it eliminates the need for software with ref cards that may not work correctly in multicard .cfgs. mostly for 1000+ core to 1065 limit.

It appears 100 % bug free even in quadfire other than the fact that ATI drivers need work for quadfire, min fps = higher, max fps = lower in 4 cards .cfgs versus 3 card.

I personally had no issues with software in single card configurations.

[GLENBOY]

It should work on all reference 4890 cards. If the PCB is different or the bios file size, do not flash it.


Reminder:
Everyone have to remember, that by flashing this bios you will loose warranty on your card. If you damage or break hardware by trying this, it is only your own fault. So, if you are not 100%, that you know what you are doing, don't do it.

Suggestion: Use latest atiflash.

Voltage + PWM design is the next issue. Hipro etc. can bypass this and then these cards will fly.

With single card you can have some gain on air as well. Most of the cards will not go too high in triple or quad CF, so in those cases this will not propably help. If you use LN2 and 3/4 way CF, it is different situation and I suggest to try this bios.

In my case, all reference (separately tested) cards failed at 1070MHz on air, but with this bios those cards could go up to 1070MHz- 1100MHz on air depending how good the cores were.

So testing this bios is the only way to see, if there is any help.
