project for tonight.

Is that Qimonda or Samsung memory?

They've both got quimonda chips on them.

So is anyone getting driver resets while in 2d mode? I edited my BIOS just like the MSI one for 160/500/750 and it's crash every so often while watching Youtube, etc. I have Dreamscene running too.....

Edit your bios for 500/750 instead of the 160 should fix your problem.

That's what I did for now......it's been working so far since last night. We'll see how that goes. Thanks fo rthe tip

RBE v1.13 is out now!

It has not many, but powerful new features.
From the changelog:

v1.13
- Added the checksum calculation method WinFlash uses because for some files, the checksums differ. See built-in-FAQ for more on this.
- Improved checksum balancing algorithm to capture this. This is a completely new method, so there might be some minor bugs, but it is guaranteed to not corrupt any file. Notify me on any strange behaviour.
- Added one-click update functionality for some 48x0 cards which corrects a well known "spin-up bug" and improves powerplay (power saving functionality).
- Added method for overdrive limit increasing. Still experimental, read built-in help text before using this. Power users only!
- Fixed bug with not properly displayed overdrive limits.

Have fun and please give me some feedback!

nice gift just started playying with bios of my new 4850 today (after purchasing and modding to watercooling yesterday )

[LuxZg]

Thanks Baggz! I'll have a look at it right away

EDIT: Nice features, I thought I misunderstood something but indeed - you get lower voltages (like in that BIOS version .029335 dated 06/17/08 11:20) and unlocked Overdrive (to 990/1200 like in Diamond XOC BIOS) as two killer features.

I haven't flashed yet, I'll first have to prepare a bit in case of a disaster, since you did give us multiple warnings But I have noticed a potential bug. If I take my original BIOS (Club3d, reference 4870 card), and unlock overdrive, save it as a new bios, and than reload that new BIOS, it again shows same (original) clocks, and clock limits (meaning 750/900, 790/1100). Could this be a bug that's related to non-US keyboards like the one a month ago? On the other hand, lower 2D voltages do get remembered, and limits are correctly read from bios files as it seems..

What else.. umm.. oh yeah, that "spinup bug", what's that? Haven't heared about it yet..

EDIT: Bug existst even if all regional options are English/US

[Oese]

i think it changes the bios to the xoc-feature. you may then open that modded bios and apply clocks and save again..

i'm already playing around with these things, no-hash (option2) does not work on my card (msi 4850), it is not recognized after flash by the driver, so far so good, but that remains after reinstalling the driver.

hash does not work if the one-click bios update is enabled at the same time, so right now i try hash only and see how that works..

btw, the us/uk keyboard bug still exists or not? i havnt had that much luck by now with changing voltages..

edit: hash does not work also, i'm stuck at 700mhz limit by now..

edit: it worked with driver 8.7 instead of 8.8beta

1000/1200 - nice

But too bad that "hash" option doesn't work, it looks much "safer"

EDIT: nevermind.. editted OUT part of post, forgot I'm in 4850 thread

[Oese]

dont know if the hash option works.. but i|m happy with none hash whatsoever

[BAGZZlash]

Should be gone since v1.12 already.

Found the bug. Expect a fix'd version soon.

very very nice BAGZZlash.. congratulation to the great work..

but.. voltage change does not work on my card..

mmh will try further..

[Oese]

ok, with gurus bios voltage works.. why not with mine?? try to mod gurus bios to be freely adjustable in ccc now.. i hope voltage information does not get lost..

[jimmyz]

voltage chang in bios doesn't work. never really will. this has been covered literally thousands of times. guru uses software to adjust and upper limit of voltage is still just 1.20 same as the others.

[Oese]

jep but thats taking me to 740/1100 without further changes (watercooled). not to complain about it.

so this is teh "secret" behind gurus modded bios, another software? interestingly, i cannot change the clocks via ccc when gurus modded bios is applied.. with my rbe-modded biosses it works..

but i understood guru modded his bios with rbe as well.. well, earlier version..

perhaps the keyboard bug is hindering me although bagzzlash said it should be abandoned...

[Oese]

ok just wanted to report that now voltage is working in bios. dont know what was the cause, but it definitely works now with german keyboard settings as well and rbe 1.13.

but it seems that i cannot use ccc clocking as soon as i set voltages for the high 3d performance p-states.. clocks will just jump back to bios values..

[Oese]

ok now did pencil mod to a light 1,2v and set idle volts to 0.9 and get this (still without ram-cooling):

[drizzt5]

woot. nvm

[Oese]

perhaps you can make one yourself? does work good with rbe 1.13

[drizzt5]

K, i'm at 780/1000 for now with a pencil mod and bios flash. What are some good, cheap mem heatsinks that I can get for a 4850 + S1 because although I'm not OC'ing my memory just yet, the temps make me uncomfortable atm. Everything else temp wise is fine.35c's idle 45c-48c's load or something like that so far.

[Oese]

i ordered the xilence ram heat sinks...

[Oese]

@ BAGZZlash: unfortunately, the modded biosses do not work with cat 8.8. That is, the overclocking limit does not apply when using the hash method, and with the no hash method the card isn't recognized correctly... Any fix in sight yet??

[Oese]

working bios-template for the cat 8.8.

important: no voltages in the last field. otherwise it will black-screen during bootup.

voltage regulation works this way, as well as bios-controlled powerplay...

this is with light pencil, so 3d-clocks will have to be adjusted to your highest achievable clocks...
