R2 335m nvidia bios flashing to increase voltage

I haven't seen much of an effect on battery life. I lost 5 minutes with this mod in 3D clocks.

This mod doesn't affect other voltages, only 3D voltages.

 

Right, but won't it draw a lot more power while gaming on battery?

 

Not really. You wont even be able to tell unless you actally got out your stopwatch.

Seriously.

 

Ok, I'm sold. I'll give it a go. Should be closing in on that 3DMark06 8000 mark!

Problem is that my memory isn't able to handle much more than 850MHz. At 860 I started getting some tearing in Furmark, but even reducing GPU or shader clocks didn't help it. Back to 850 then it was fine. If I went about 860 it would periodically crash in a 3D app. ajslay got lucky with 926MHz vRAM, as did you with 900MHz!

 

Well, not sure if I gained a whole lot.

With 1.73GHz CPU (as confirmed by CPU-Z) and volt mod to 0.95v (as confirmed by GPU-Z)

GPU without volt mod (0.90v) GPU 560 / Mem 850 / Shader 1380 3DMark06 ~ 7200
GPU with volt mod (0.95v) GPU 600 / Mem 850 / Shader 1400 3DMark06 ~ 7300

Anything much more with any of those I'd either get a lockup or texture corruption. Just luck of the draw I guess.

 

I saw even less. I went from 600 to 630 or so. id say you got a nice bump there and that your 3Dmark is maybe refecting the CPU bottle neck.

But in the bigger picture, your a good amount faster than you were a few days ago.

 

This is true. Now for that 2.0GHz mod. You up for it? lol.

 

yeah it is the luck of the draw. i think im one of the only ones that can actually get over 1500 on the shader clock.

 

That seems like a worthy gain for the voltage increase- remember it's still less then 1v. Most users have reported an additional 40-60mhz gain from this mod.
Consider it a "free" increase- hopeless 335s are upgraded to decent clocking 335s, decent clocking 335s are now upgraded to good clocking 335s for very little battery life loss which is only noticeable when gaming under a stopwatch and nearly unnoticeable heat increase (74C to 77C in 30C ambient).

That's because you're already have a high clocking GPU. Consider it now one of the fastest 335Ms on this board, second only to DR650SE's 335M. Even better if it's stable.

 

has anyone else been able to get above 1500mhz on the shader clock? i can get up to 1530mhz but then i get some small artifacts. and 1510-1515 is stable for me.

 

sure.

yea i figure around 600mhz is the wall. we could try to keep adding more voltage but i think it will be minimal gains.

where have he been? he was gonna test that RAM with the pinmod.

shame on him!

i start artifacting around 630-640mhz. thats why i haven't re posted my 3Dmark. i got a 8182 tho with a few artifacts.

 

yeah, I was able to push 615/860/1460 but with artifacting, and a lockup on one occasion.

I'd send my M11x out right away for 2GHz mod, but my Sager has to go out any day now for the Intel SATA recall fix, so will need my M11x for my main portable computing needs. It will be my temporary desktop replacement. I think I'll hook it up to my Dell 20" 1680x1050 monitor though, 1366x768 is a tough resolution to do any eral desktop work.

 

whenever is cool for you.

i was using my R1 for my main PC for a while while my desktop was down for the count. played the first half of Portal2 on it and it was a pleasure @ 2.0ghz.

 

well only 2 more days til i do the 2ghz mod. im getting pretty excited.

edit: you guys are lucky to be pushing past the 610mhz mark for the core clock. if i go past 607mhz the drivers crash and go down to 2d clocks.

 

I just ran some more burn-in of OCCT, Furmark, and 3DMark06 and got some slight artifacting. Ended up having to run at 590/835/1390 and with that everything seemed more smooth. Seems like when it's on the verge of artifacting or locking up you can get occasional skipping of the frames. It didn't affect my overall 3DMark much at all, only dropped by ~ 10 points.

 

How do you determine if your videocard is stable when running OCCT? I ran it for 30 minutes the first try and I see errors and I monitor the temp of the GPU which seems normal. Is there a guideline? Thanks in advance.

 

I'm running 170FSB CPU and 610/900/1390 on the GPU. I think i'm really lucky and have got a decent M11X. Tearing through all my games OC'd. With CPU and GPU stock its not that great OC'd the M11X is a bit of a monster!
All I need help with now is better RAM or flashing to higher timings so I can up my FSB to 175/180 . I'll be snapping at the R3 and R2 i7's heels then!

 

Did you say you saw errors, as in texture tearing or corruption? That means something is set too high. Or it will flat out just error out or lockup. I also noticed if I was on the verge of stability, I would get occasional skips of frames. Dropped my clocks by 10 for GPU and shaders, and 5 by memory and smooth all the time.

I normally would just monitor furmark or occt for the first two minutes and usually something would rear its ugly head by then. Once I got where I thought it was stable I'd run it for an hour and just check on it occasionally. If I saw tearing, corruption, skipping, or anything I'd back down the clocks a bit.

 

I think I'm okay now. I'm currently running it at 585/1404/860 and no errors yet. The temps are 42/66. My 3dmark06 score is at 6930(R1). That's about a little over 100+ score. Still will need to run more test but so far so good. Thank you.

 

Did you do the pin mod to increase your CPU or are you with stock overclock from BIOS? I only ask because my clocks are similar to your but with 1.73GHz CPU pin mod (SLG PLL), and get just under 7300.

Also note that if you were testing and something crashes, and get a notification that the driver has recovered, then reboot. Otherwise it downclocks things on its own because my scores were nowhere where they needed to be. A reboot would reset things. With all the reboots I did, this is where my SSD came in handy.

 

thats a nice OC for an R2. what your 3Dmark? 9k?

 

no I didn't do the pinmod. I'm at stock overclock (1.6ghz) with Speedstep disabled.

 

Hi,

I made many tests and i figured out, that the more of voltage doesn't change anything!

I run @ 535Mhz and i can not go any Mhz higher - with or without the modded Bios!

could this be possible? Or am i doing something wrong?! (GPU-Z shows the 0,95V with modded bios...)

 

not sure, the voltage increase works for me.

 

the voltage increase works for me too - but i have no affect on further overclocking ?!?

 

You hit a wall on your core and it just won't clock any further. Needs a bigger voltage jump before it can clock higher.

 

Had to knock the Core down but bumped the shaders a fair bit!
My 100GB OCZ Vertex 2 is coming on Tuesday so gonna do a fresh install, tweak my RAM, up my up my FSB then get my 3D mark score.

 

any chance you can update the first post, and change the title??



EDIT: someone pinch me... 580,1410, 915 core/shader/memory

No fragments, core is at its max, IDK about memory/shadder, its still going higher....



EDIT: I gave up after 583,1470,940 because the core was holding me back...

 

try this cooler......
YouTube - Homemade Laptop Cooler

i can overclock more on my G105M without increasing its voltage using this cooler.......

 

Can anyone explain how it works? Does it change whole bios of system or only videocard one? If system one then which version of bios it will install? More info please.

 

Try focusing on the core. It may have greater gains then the shaders.

It's not my thread so I can't update the first post. I did update my post though.

That means you're too hot.

It works by reinstalling the whole BIOS as the GPU BIOS is integrated into it. No other changes besides adding more voltage to 335M's 3D clocks. There is only one version for each M11x revision, you should choose R1 version of the mod because you have an M11x R1.

 

And version of this r1 bios is 1.05? I mean the latest one? Cause higher voltage is ok, but if its something old like 1.04 that's fail )

And what if i want to revert bios back to original?

 

Yes, the R1 version of this mod is A05.

If you want to revert back to stock BIOS, flash the stock BIOS over it. ajslay can fill you in on how to flash to the BIOS.

 

Really? When OC'ing with OCCT I noticed the fps increase significantly with an increase in the memory clock (and no noticable increase with the core). Although that was after I had OC the other two til max.

 

Driver still dies on 585 \ 1350 \ 900 even on 0,95

 

some people wont see a difference, i think you might have hit a wall on your clocks. to get it higher would require more of a voltage increase.

 

try higher memory/shader clocks... my core will only do 583(ish) but the memory and shaders are good to 930 and 1460...

 

I'm in a similar situation. I run at 590/1390/840 so you're even better than me with the vRAM. I can run at 600/1420/850 but with some artifacting on occasion. Backed off to these values and it's rock solid. Actually I could go as high as 620/1450/865 but there was artifacting everywhere. I should run it at though just to see my 3DMark06 score.

is there a way to flash this in bios because i dnt feel comfortable flashing within windows? Also i got an error trying to flash the vbios, it said that the bios was the same version :/

 

do this...

 

Thats all i did too.

ajslay has a recovery guide as well if anything should go wrong.

 

Just out of curiosity, how hard would it be to further modify the bios to set higher clocks for pstate 0 rather than using software to overclock?
*edit*
More specifically 550 core, 850 memory, 1320 shaders.

 

I haven't had any luck flashing higher clocks as Nibitor only has partial support for it. Flashing increased clocks disables the 335M.
Here are some other mods I tried, all failed:
1v BIOS mod
Crossflashing the Quadro FX1800M
Crossflashing the GTS 350M, 360M BIOS

 

davy how about the 540M in the R3?

 

That should support a .02v overvolt from .98v to 1v but I'm not releasing it until it's tested working this time around with the recovery guide.

Haven't made any progress with the 335M vmod, still sick.

 

Davy, what will the new VMod do? Higher voltages? I should have my ICS pinmodded m11x this week.

 

The new vmod will enable higher voltages on the GPU or CPU. Since both the GPU and CPU use similar voltage regulators (ADP3211 and ADP3211A), the mods to increase voltage will be the same.
This mod only applies to the R2 only so though as the R1 already has a CPU VID mod. Not sure where the R1 GPU voltage regulator is.

 

That's cool. I may end up trying to sell this to pick up an r2 because I need the better CPU for the things I do. How much of a difference is there between an SU7300 at 1.8GHz and an i7 at 166MHz w/TS?

 

OMG DavyGT your actually gonna release a BIOS which will allow more voltage on the GPU and the CPU??

I need to sort a 32Bit OS, better RAM, a laptop cooler and Thaiphoon burner to sort my RAM. I want 2.2GHz with 4 threads

If I can go further on the GPU that would be awesome! R3 watch out
