najili Posted December 5, 2012 Share Posted December 5, 2012 I'm a new user here, I still don't understand about how to flashing or unlocking bios. Can you all teach me and help me unlock voltage?? I'm using Acer Aspire V3-571G , i7-3630QM, NVIDIA 640M, 8GB RAM . Windows 8. I'm using this bios : BIOS_Acer_2.04_A_A.zip Quote Link to comment Share on other sites More sharing options...
vnvman Posted December 5, 2012 Share Posted December 5, 2012 Let me jump on the bandwagon. I've got the same PC and no modding skills whatsoever, therefore I strongly support this thread Quote Link to comment Share on other sites More sharing options...
Founder Michael Posted December 6, 2012 Founder Share Posted December 6, 2012 According to our bios guru @svl7 machines that come pre installed with windows 8 have very slight chance of getting a modified bios. 1 Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 True... depends on how exactly the secure firmware upgrading method is implemented. Can any of you V3-5xx users with a 2.x BIOS provide me with a dump of your system's firmware?Grab the tool here and use the command below. Then send me the file or attach it to a post.fptw64 -d dump.bin -bios 1 Quote Link to comment Share on other sites More sharing options...

When I run the command it lists 2 device IDs with their respective sizes, but then in the line below it says Error 104: The 2 SPI flash devices do not have compatible command sets.What does this mean? Forgive my noobieness but I'm actually totally new to this...thanks for your time. Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 This means we got a problem.What does it say if you use the -spibar command? Quote Link to comment Share on other sites More sharing options...
vnvman Posted December 6, 2012 Share Posted December 6, 2012 This means we got a problem.What does it say if you use the -spibar command?It gives the same ouput as before and displays the same error. How "bad" is that? Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 Well, if we can't access the bios chip we can't flash anything either. Do you happen to know what kind of eeproms your system uses? Quote Link to comment Share on other sites More sharing options...
vnvman Posted December 6, 2012 Share Posted December 6, 2012 I don't know, how do I check that? Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 Well, in this case I'd say only by looking at the mobo or at the notebook schematics, but even if we know the chip model, the chances to get it working are very small. Quote Link to comment Share on other sites More sharing options...

Too bad...I picked this Acer laptop mostly for the BIOS mod you made. Too bad the first one I got was faulty, so they had to replace it with the newer Win8 version, because apparently mine was the last unit they had. At first I thought I was lucky, but right now thinking again...maybe not much so.It's a shame that we can't overclock past 135 Mhz, which is worthless anyway because the boost frequency stays locked @844 Mhz. Sure we're left free to OC the memory all we want but with DDR3 memory you don't get far that way. Is there any possible exploit to use in order to get a higher OC, besides unlicking the BIOS? This card is so wasted locked down at such a low speed Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 Did you ever try to flash an 1.x bios? Or isn't it compatible? You might be able to flash a modified 2.x bios with the USB recovery method... but that's not my preferred method.You can overclock past +135MHz with Nvidia Inspector, but I'm afraid the overclock might get reset due to some vbios restrictions. 1 Quote Link to comment Share on other sites More sharing options...

Yes, apparently I can't even set a higher clock: Nvidia Inspector only shows a maximum OC of 135 Mhz for core and 900 Mhz for memory. Unlock max and min buttons are greyed out. I may try to flash an older BIOS, but how risky is that? I wouldn't like to brick this thing Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 6, 2012 Share Posted December 6, 2012 Well, if it allows you flash, then it's ok. Else probably not.You need to force a different P-state with Nvidia Inspector, there are some commands which you can use, can't remember them properly. If you start Nvidia Inspector with the -h flag in cmd then it should show you all the commands.The idea is that if you force the card to use the lower 3d profile instead of the full 3d, cause it usually has different overclocking limits. This will only work if your vbios has such a P-State. You can't use the 2d P-State for this since the voltage would be too low. Quote Link to comment Share on other sites More sharing options...
vnvman Posted December 6, 2012 Share Posted December 6, 2012 I tried to run nvidiainspector follwed by -h flag as you said but an error message popped up saying that command isn't valid. I guess I'm stuck with P8/P0 states...I also tried to OC via .bat scripts but I still can't push it further. As to flashing 1/2.x BIOS, I just read in the BIOS mod thread that a guy tried that but wthout success. I guess I'll have to deal with it. Funny tho because I had a few laptops in the past which allowed higher OC without any mod, I guess I'm out of luck on this one, hehe. However BF3 still runs quite decent on high with the memory clocked @1200 Mhz, not too bad after all. Quote Link to comment Share on other sites More sharing options...
najili Posted December 8, 2012 Author Share Posted December 8, 2012 So, how to solve this? Quote Link to comment Share on other sites More sharing options...
vnvman Posted December 9, 2012 Share Posted December 9, 2012 So, how to solve this?Apparently there's not much we can do: seems like this model is very locked down. You can still acquire a small OC via NvidiaInspector but that's it. However memory is free to OC as much as we want, but I found that beyond 1200 Mhz the performance actually drops and you get artifacts, or at least in BF3 and CS:GO I know I do. That's not as bad as it sounds tho, you can still get 10 more fps avg out of BF3 compared to stock with this OC, and with the higher memory clock I guess you'll be able to improve AA and AF on most games without too much pain.
