Starting to go a bit nuts. But is anyone noticing GPU clocks randomly resetting with the 2.04 mod?

Thanks.

no news with HD4000? even with a HW "hack"? the single 650m consumes a bit even in idle.... just a dream to resurrect that videocard from the i7?

I have a question, you can make a little instruction movie and put it on youtube, because I do not understand the bios mod thing step by step

it's easier if someone explain to me step by step and i live in holland therefore it is difficult for me

I get 2 errors when I try to flash moded bin in Bios. PDR region does not exist and error 25. Ideas?

Fixed problem. In my haste to flash I wasn't typing the -bios at the end of the command line.

I just set a new 3dmark record :pride: although It did not save to my account because I did not delete my previous one and I did not pay for the pro version; and for some reason it was submitted twice. Anyway here is the link.

NVIDIA GeForce GT 750M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

Wooh finally someone broke my record. What clock and what voltages are you running?

I am selling my Y500 soon so I won't be oc'ing on it anymore, if not I will really try to break that score. :friendly_wink:

Nice, that's pretty awesome. With my 650M SLI my highest is P5228, currently sitting at #3 on the list for 650M systems. Clocks were 1260/2250 @ 1.137 V. Not practical for everyday usage because the GPU's will get up to 97-98 C and start throttling, so I use it just for benching. At my everday clocks of 1120/2250 temperatures are 20 C lower. It's crazy how much extra heat is generated when you bump up the voltage.

Is your Y500 the replaced Y500? What happened to the one with problems?

How could you guys get 7500~ Physics score on 3D Mark 11 ?

Every time I try, I get only 5500~ Physics score, please help...

I can't wait to try this flash! I'm getting a y400 from Ebay in the next week. I was conflicted for like a week debating whether to get the y400 or y410p but I think I'm glad I chose the y400...the y410p has no modded bios yet!!! Also, I'm still an amateur at flashing bios...I've only done it once before and that was way back when...but does anyone have any recommendations on 3rd party wwan/wlan cards for the y400? I'm guessing that its a huge plus to use your own choice...I just don't know whats good for the price. Any recommendations would be appreciated feel free to respond back or PM me thanks!

Yes this is the replacement unit. I returned the defective one of course.

You need to use ThrottleStop.

So what's the deal with this throttlestop thing? I don't think any intel processors would throttle their frequencies when something intensive like 3Dmark is running, so why is this program necessary? Also, is the 2.04 BIOS update for the 750m available for download from the front page, or do I have to look through the forum? Thanks :)

I believe according to chmod1337 in a reply to me he said the BIOS mod posted works for the y500 750sli no problem. the 2.04 BIOS posted is a Modded version of the stock 2.04 bios unlocking locked features (make a back up! if you decide to flash) because it does void your warranty with lenovo and you'll lose your Win8 Slic license.

In theory they should only throttle when running on battery mode, to save battery life and prolong it. However what I saw is that they also throttle to save and prolong the quality life of the processor even when adaptor is plugged. Basically is a safety measure.

Has anyone kept any records of temps on the Y400 using throttlestop as opposed to without it? I'm wondering how much hotter it runs on average with the small laptop heatsink in there.

Alright I guess that makes sense. Never had a processor die on me before though. I've been running an AMD Athlon II x4 620 for the past four years, and it's been overclocked from 2.6 to 3.4 GHZ for the entire time. I wish Intel would give us an option to manually engage turbo boost whenever we want.

do these bioses (sp) help with anything other than whitelisting? meaning i have a y500 with 2.00 bios, and the 2.6GHZ cpu and no ssd. I bought it this way because I knew I would be upgrading the ssd anyway so why not get speed and no waste right?

anyway, the machine sometimes does not recognize the msata, and won't boot. to fix this, i either change the bios back to EUFI (or whatever it is) from legacy, and back again. this seems to work...

I know the msata works, because i have windows 7 installed on it and it runs great. it just sometimes doesn't boot right away. I was looking for something that might fix that?

Thanks for any feedback

Could someone lend a little help? I've flashed the modded 2.04 bios on my y500, and now I'm trying to flash the overclock file for the SLI 750m. I have the appropriate rom on the root of my flash drive (named 750.rom), however when I run the "nvflash -i1 -6 750.rom" it shows a few lines of text and then ends with an Error message: "A newer version of NVflash is required." Has anyone else experienced this message before? If so, how could I get around it? Thanks. Also, are there any settings worth modifying in the unlocked BIOS?

Once I flashed this bios I started having bluetooth issues when putting the laptop to sleep. It's a known issue with the Y500, where bluetooth fails to work when waking the computer... however, I didn't have the issue before flashing. I use a bluetooth mouse, and prefer to keep windows quickboot, or whatever it's called, active. Since I have no plans of overclocking, I'll be flashing back to stock, until I pick up a different wifi card... but just wanted to let it be known. Perhaps it was just a fluke with my machine, if not, hopefully it can be fixed in a future release. I was on 2.02 stock.

The Bluetooth issue happens on stock BIOS too. I've already confirmed it on 1.05 and 2.02, both stock.

Oh, I know, it's confirmed by many on the Lenovo forums as well. It's odd though, I've flashed my backup and have no issues now. Tested several times... so something was up. A bios setting perhaps?

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.

      I fiddled around with modding my laptops BIOS to unlock XMP profiles and hopefully seeing if optimus could be disabled. After flashing my modded bios and trying it out, I noticed that my keyboards backlight no longer turns on. I was unaware it requires an official BIOS to function. They backlights wont turn on unless ASUS ATK package is installed but now it seems it also needs an official BIOS?
       
      The modded ROM and tool I used if anyone has any experience with this and doesn't mind telling me what to enable/disable, or anything else i can do to re-enable them

      Hello !
      I tried a tutorial on the forum to remove the supervisor password on a X260 thinkpad but the winbond 25Q128FVPQ chip is not recognized with the programmer CH341A and ASprogramer (does not detect automatically and not manually). Plugged into the motherboard with a soic8.

      Can you help me with detection?
      Can I find the password with the software or do I have to write it?
       
      Thank you so much !!!
