groovelite Posted December 23, 2012 Share Posted December 23, 2012 svl7, a member on notebook review, in the thread regarding owners of the Dell 7720, uploaded the batch file for flashing and the two mods, 00 and 01. I previously read through this TI thread and had some understanding of what your VBIOS mod intended to do. If you look through notebook review thread, I believe the post including your modifications is somewhere around page 148. 1 Quote Link to comment Share on other sites More sharing options...
Dmitry Matveev Posted December 23, 2012 Share Posted December 23, 2012 I get a brick, when flash at 970. nb is 7720-3884 What i do: 1. Flash @ A11 from Dell's off site 2. Flash @ AES vMod 835mhz 3. One day later buy Arctic Silver Ceramique and get NB for "turbo mode" xD 4. Try to flash @ 970 mzh - failed on start. When i think what need back on "clean" A11 and do it... 5. But when flash is ok - NB reboot and ... i got brick.. x_X - not read usb with "crysis mode" =( no power on external ports (sata, usb, fans, etc - work only kb backlight and matrix test). For recover I get rom chip from other NB (7720-6174) and create dump with prog device. Then this binary I'm uploaded on my chip and moutherboard can send power and read ROM from USB. But NB not started normally - black screen, fan speed is 0. What now: - reflash with factory flasher A11 - brick. - reflash @ any mod from here - brick. - system can load if rename "boot.rom" to "boot.cap" from 835mod and only from USB (this is ROM i flash before in step 2) - Windows loaded nornally, if after boot ROM from flash enter to BIOS (F2) and exit with save (F10) Any ideas? Work any time load BIOS from flash not fine, I think P.S. I can create binary from my chip, if it can help resolve problem P.P.S. Sorry for bad English ;D Quote Link to comment Share on other sites More sharing options...
groovelite Posted December 23, 2012 Share Posted December 23, 2012 Patrick, typically I experience an idle of 50-55c, and 70-76c under load. However, in BF3, after prolonged play, logs show the card hitting 90c. Literally as soon as I exit BF3 and check my temps it returns to 70c, and therefore I do not believe it to be a problem with the heat sink as it dissipates heat very quickly. I will consider changing my thermal paste should the temps continue to reach 90. I just had the motherboard replaced by a Dell tech for the previously mentioned failed flash from Mod00 to A11 (again, I in no way believe this to be a problem with svl7's mod, as it was running perfectly, but rather an issue with Dell's installer package), and I will see how the temps look with this new installation. Also, I do not use a laptop cooler/external cooling of any kind, and we may be comparing apples to oranges. Quote Link to comment Share on other sites More sharing options...
Dmitry Matveev Posted December 23, 2012 Share Posted December 23, 2012 attach binary from 7720-6174 readed from chip with programming device. maybe can help someone 7720-6174-A11.zip P.S. Is binary was readed from new NB, but flash it on A11 ver. (from Dell's official site with standart method) Quote Link to comment Share on other sites More sharing options...
groovelite Posted December 23, 2012 Share Posted December 23, 2012 Alright with new motherboard and stock A10 (came with new install) BIOS, I am maxing at 77c in BF3 for 30 minutes with no external cooling, CPU turbo (i7/3630qm) enabled. So in Mod00, it appears my GPU was seeing significant increase in temps (90c @ 835mhz in BF3), though it is difficult to compare as I now have a replacement board in the system.

Dmitry Matveev Posted December 23, 2012 Share Posted December 23, 2012 Now in BF3 (835mhz) with thermal paste replace\no external cooling - i get not more ~75-80c, but need to load bios from USB anytime Change MB @ warranty not good idea for me, i think More 5 times i was get\insert rom chip from MB, but i will try after russian's holydays. And, I if can't resolve my "little" problem in next 3 weeks. Quote Link to comment Share on other sites More sharing options...
svl7 Posted December 23, 2012 Share Posted December 23, 2012 @Dimitry: Is the coin cell battery ("cmos battery") plugged in and working? Also are you sure that your bios chip is functional and soldered on properly? Quote Link to comment Share on other sites More sharing options...
Dmitry Matveev Posted December 24, 2012 Share Posted December 24, 2012 @Dimitry: Is the coin cell battery ("cmos battery") plugged in and working? Also are you sure that your bios chip is functional and soldered on properly? Yep. Battery is ok. Chip was soldered proper. I'm sure! )))))) Just I'm remember: in 1st time, then unsolder chip, previously I made a dump - i'm pay attention on visual differences of 2 dumps (software shows HEX two versions before flash). Strange, what software bios versions (A11), chip models, .rom file sizes - it was identical. Apart a strange result in fact - mine chip dont work, after reflash on official release... How show mine humble experience, what big difference with same troubles will not to be . But I can be wrong - because dumps was made of two difference notebooks - part and serial numbers, release dates, hardware parts setup and etc. Is all are it logical? I'm not sure. Or I skip some details. Maybe upload to here a .rom file what I'm used in 1st time? And why after official reflash, without errors, warnings, bugs - BIOS work fail and power turned off on external ports? Why, after hardware chip reflash - motherboard send power on external ports, but after again reflash with official tool - no get power again? WTF? Heh, so many questions)))) Will be fine, if I can find binary dump from 7720-3384, created with programming device or without it, damn. (( Maybe, it give chance to help in my trouble resolve . Don't know... Any case, IMHO, problem need solve here - for experience and excluded such failures in future. Regards. Quote Link to comment Share on other sites More sharing options...
Focus909 Posted December 24, 2012 Share Posted December 24, 2012 Yes it was me that posted on NBR the files. My Apologies to svl7. Didn't mean any harm and post contained link and credits to this thread. Sorry. Quote Link to comment Share on other sites More sharing options...
nothingknow Posted December 26, 2012 Share Posted December 26, 2012 Hey guys, I flashed successfully (no bricking!) the from RadioDOT linked BIOS mod, which combines svl7's GPU clock and AES-NI patches made by ixbt member Serbius (page 6). And now I have full AES support!TOP guys! You will get one more beer I have got a question: Can I overclock the 650M more than 970Mhz? How? MSI Afterburner and Nvidia Inspector allow me only 970Mhz. And for those guys failing to run the flash.bat, you have definitely to DISABLE the UAC-Control from Windows with msconfig! Quote Link to comment Share on other sites More sharing options...
Olol Posted December 29, 2012 Share Posted December 29, 2012 I´d like to use this BIOS Mod too. But I have some questions now. Which is the newest Version of your Mod? The version posted at page 11 or the one on page 6? If i didn´t misread there is one version with aes support and one without. Which is which? And finally my last question. How do you install your mod? the BIOS Update from Dell was an executeable. Is yours one too? Quote Link to comment Share on other sites More sharing options...
Olol Posted December 30, 2012 Share Posted December 30, 2012 Ok. It is no executable. How do I apply your mod then? I must say I have absolutely no clue. Also, does your mod allow me to get higher than 970mhz? Quote Link to comment Share on other sites More sharing options...
X-dude Posted January 6, 2013 Share Posted January 6, 2013 Hows everyone whos using the modded bios computer doing? Also what is the highest clock speed the gpu can be set to without the modded bios and using a program such as nvidia inspector as long as the gpu doesnt get over 90 degree Celsius.

Toopy Posted January 22, 2013 Share Posted January 22, 2013 to anyone that has bricked their board, the recovery process is here.[Request] Dell Inspiron 17r SE 7720 Unlocked Bios Quote Link to comment Share on other sites More sharing options...
Toopy Posted January 23, 2013 Share Posted January 23, 2013 actually a 950/2800 bios will be fine sv17. Thanks or just let me know what to edit in the bios, Quote Link to comment Share on other sites More sharing options...
SuTuFTW Posted January 31, 2013 Share Posted January 31, 2013 Would there be a way to modify the bios so the 650m would become a 660m? I heard that those two are physically the same. I know that 7720's cooling solution wouldn't be able to keep it chill (or maybe?) but lets not think about that for the moment Quote Link to comment Share on other sites More sharing options...
Xyphir Posted February 6, 2013 Share Posted February 6, 2013 Hi, I purchase this laptop a few days ago and eagerly waiting for it to arrive, sense then i been reading about some issues with it. One of the issues is GPU Boost disabling after unplugging the AC. Only fix apparently was to turn laptop of remove battery and reinsert it. A few questions to anyone who has time to help Does this mod fix the gpu boost disabling issue? Does it change the clock speed to 970Mhz with gpu boost or just changes the stock clock to 970 and turns boost off? Thanks in advance for any help.

Xedos9er Posted February 15, 2013 Share Posted February 15, 2013 Any news here?The 17r SE reacts very strange to OC. Everything over 970mhz core gets unstable. I don´t understand why... the alienware guys are squeezing out 1100mhz+, and we can´t go further than 970 :-(What could be the reason for this?ATM i have no bios mod. Just overclocked via NvidiaInspektor to 970mhz and checked the voltage: Idle voltage is 1037mV.But at high gpu load it drops to 1012mv. I also disabled CPU Boost by switching maximum CPU usage to 99%, to be sure that it´s not a heat problem and to safe power. My temps are at 66-70°C on GPU and CPU with CoolerMaster Notepal U3.The PSU (135Watts!!) should be strong enough to handle the GPU OC with disabled CPU Turbo Boost. Is this voltage drop normal? I think this might be the reason for instability issues. @svl7Any chance to check this? Quote Link to comment Share on other sites More sharing options...
Xyphir Posted February 19, 2013 Share Posted February 19, 2013 Can i use this with the newest bios A12? or do i need to use it with only A11? Thanks Quote Link to comment Share on other sites More sharing options...
x5eito2 Posted February 20, 2013 Share Posted February 20, 2013 Hey, Used the latest 970 clock bios from svl7. Was good for an hour, untill i shut down the notebook. Now seems to be bricked, wont turn on proper. Only the leds turn on and hd spin for a sec, thats about it. Any tips?same issue here. temps were fine after flash (about 30 mins of ss3, not more than around 80) , boot after first real shutdown failed. i'd wonder if gpu was responsible. didn't get original bios flashed back so only solution for me was change of mb...
