700mhz wall on HD4850 is smashed.

[Jaystar]

I have a dmm hooked up to my card for testing. With a pencil mod done. I get just around 1.290v loaded regardless of what voltage I set in the bios. Is there any trick to getting higher voltages threw the bios?

[korda]

BAGZZlash:

After I change clock info 3 and 9 to my OC value (715 MHz) and saves the bios only nr 3 stays at 715. Nr 9 changes back to 500. Whats even more weird is that clock info 6 changes to 715 MHz instead.

But it seems to work anyway. The GPU jumps up to 715 in rthdribl, so I guess it works in games too.

Should I edit the bios again and only keep 3 at 715?? Clock info 6 ain't for 3d right?

This is a Gigabyte bios btw, same one as Sapphire uses.

2D voltage is 1.046 and 3D 1.084.

[cowie]

ok i'm like pissed, man no friggen software to clock as high as we dare?
i topped out 700/1200 and no volt mod yet.
to have to bois flash to o/c is not what i'm used to

[JamesBong420]

really amazing!

did you just solder pencil or did you solder a vr?

I also wonder if a 4870 can reach even more :P

i use a 100k VR... i dont use pencil anymore.. its not as reliable..

mmmm... mmmm.... might slap one of these on my 4850 :P

Would anyone care to bench something at 750 GPU and stock memory for comparing 4850/4870 GPU vs memory?: http://www.xtremesystems.org/forums/...d.php?t=192690 Been using games and settings used by the 4870 reviews in order to compare results.

Then write it. If you think what W1zzard and BAGZZlash ( and others)do is easy, write some yourself. Nobody pays these fine people, they do it to help the community and ask for nothing but the occasional thank you or other compliment. Many people have spent a great deal of time, effort and even money to bring this information to you on a silver platter. you should be thankfull there is even a way to get above 700, it took a lot of effort to get this far.

For anyone who is interesed, I have modded the 4850 MSI bios....not only have I raised clocks and voltage under load, but I have improved on the powerplay feature as well as the fanspeeds. IMO this is how it should have been shipped from the factory...it is a bit loud while gaming and such but this way the cooler is actually effective!:





The fan will only go down to around 25% in idle and 2d clocks, but it's pretty much inaudible and during 3d clocks should keep it under 70c full load, more like mid-low 60s.


All the reference 4850s should be able to do this, but if you are getting crashes then I can make you up a slightly less aggressive profile, or you can edit it yourself with the RBE tool. I recommend stress testing with rthdribl and some Crysis benches.

Thanks for that BIOS Gurusan. It works a treat for me Its good to actually hear the fan doing some work under full load!

*snip*

I think the fan is doing a bit to much work if ya know what i mean
I'm gonna try and pick up an S1 over the weekend.

And did the 2d profile work for you? or am i alone in that issue?
I've reinstalled so many drivers today and yesterday I'm thinking of just doing a fresh windows install :/ I might have really jerked with some crap in the registry. it'd be nice to have an official driver actually.

[Bitgod]

Hey guru I'm having an issue with the 2D profile working with your BIOS. It seems to run with the 3D settings all the time. I did, tweak it a little, but just for the Fan profile.


Also (possibly) unrelated, this is what happens to the Overdrive tab in CCC for me, it occasionally flashes to show what should be there, only with blank values. (see attached file) I don't think that should be normal
This is with the Hotfix Driver. I've tried reinstalling it, seems to only be a CCC issue, as the in game performance is solid so I dont think it's in the drivers. I'll try stressing it with the crysis bench and see if maybe it just isn't stable?

Isn't that normal for using Aero Glass in Vista though? I know on my card, monitoring my system with Everest on my G15 LCD, that the GPU speed on my 8800GTX is always at "3D" speed, it never changes. That bugged me until I realized that it must be Aero Glass since the desktop is kinda always in 3D now, if I boot into my XP 32-bit install, I found that being at the desktop there, the GPU was running at "2D" speeds.

In an ideal world, I'd like to be able to do something like run the GPU at something lower, maybe 500Mhz for starters by default, and then when I go to play a game, some app has a profile for that game and kicks in to OC the GPU/RAM.

That said, my 4850s that weren't supposed to show up until Tuesday showed up today So I need to crank out some benchmarks on the old card first just so I have some comparisons between a 4850 and 4850 CF.

I'm not using aero glass though Windows classic look FTW! I like my Vista to look like 98

The only reason it bothers me is because it makes the fan run loud (~70&#37 all the time. I wouldn't mind it if it were just in game but I like my silence the rest of the time.

2d is working for me. GPUz always shows me the 3d clocks in the main window while the 2d clocks are shown correctly on the sensors tab. My idle temps are a lot better too.

2D isn't working on any of the BIOS for me. hmmmm, is there a power saving mode you have to enable somewhere that i'm missing?
I've tried what seems to be all the drivers, and tried them more than once, but it just wont kick in to 2D mode no mater what...

in the sensor tab? did you check it, the front "page" will show the 3-d clocks but the sensor tab should show real time clocks.

I have a dmm hooked up to my card for testing. With a pencil mod done. I get just around 1.290v loaded regardless of what voltage I set in the bios. Is there any trick to getting higher voltages threw the bios?

a way to increase the voltage is to shade the resistor or point harder/darker. This will give you less resistance and more volts. Always check with the dmm though so that your card won't blow up.

Yeah even the sensor tab is showing the 3D clocks. And the temps reflect it, so I know it's not just a program bug. I'm at a loss.

Gonna try on more driver reinstall.

[D749]

I was eager to get down and dirty with RBE after having my card run stable (e.g., 3DMark Vantage/06, FurMark, Lightsmark) at 700/1000 (set via CCC). However, after one adventurous clock to 700/1100, where things started to crash, I can't get back to 700/1000 without crashing! I'm not sure what the hell is up.

Threw up a post about it here if anyone has any suggestions.

[biftek.]

OMG I finally figured it out.
Apparently having dual monitors forces the cards into 3D mode
That better change with a new driver.

Anyways, I'm finally enjoying a quite computer sans one monitor, and once again low temps.
That better be fixed with the next driver, there is no reason two monitors should count as "3D".

sry to offend you
but i never said it was easy.
and i know that you had help from some of the best guys in the community getting where you are now.
i geuss i just took o/c programes for granted using nvidia products for the past few yrs.
but like i said bios flashing not for me since it voids my warrenty with the brand i use plus the fact i dont like to have high clocks all the time
again sry to get your wares in a knot
just a rant by me

good to hear and impressive score!

thats the intended behaviour. first page will show the 3d performance clocks and sensors will show realtime clocks

[D749]

Out of curiousty... how well do all of your overclocked cards hold up when running FurMark (http://www.ozone3d.net/benchmarks/fur/). I'm able to run 700/1000 at 1920x1200, with the fan cranked up a bit, in rthdribl (x16 multisample), 3DMark and games. However, running FurMark will bring my card to a halt.

Thanks for the clarification W1zzard. And 2 thumbs up for all your work for the community.
