Yep, look's like this BIOS settings don't work.

 

Any chance this BIOS setting may be connected to memory module SPD?

 

In theory i may try to lower same setting in BIOS to 1333MHz and run AIDA64 test again.

What the RAM settings you use in bios setup menu? Post photo.

1. Memory Frequency in Chipset Configuration [1067/1333/1600/1867/2133];

2. NMode in Chipset Configuration (1N/2N).

 

And here is results with 1333 MHz:

So, options partially working. If SPD is present - it working.

Try to search in bios setup menu the setting  "DIMM profile", and set it from "Default DIMM profile" to "Custom profile". Then set Memory Frequency to 1866.

I didn't saw such setting. I have got Y500, it's probably was cut. The only thing i can enable for DIMMs is Thermal Sensor if module have got it.

 

And last test for testing CPU unsupported memory frequency (1066 MHz), but included in memory module SPD:

So, i need to find 1866MHz memory module to confirm that this BIOS setting checking memory SPD for succes boot.

Today i finally tested memory modules with 1866 MHz:

 

i7-3820QM + SK hynix HMT41GS6BFR8A-RD (+ThrottleStop with multiplier 35T - 3.5GHz on all cores). This modules have balck PCB.

Memory_N1_i7_3820QM_SK_hynix_HMT41GS6BFR8A-RD_1866MHz_16Gb.thumb.png.1f76694d8b301d6b2e1e5a672dd3c2b1.png

At previous page i replaced screenshot with AIDA64 by new one. I re-runned this benchmark also with ThrottleStop.

 

1. Memory really working on 1866 MHz;

2. Better Read\Write\Copy (because of higher frequency);

3. Not much performance diffirence (because of high timings. if calculate latency - Ramaxel - 13,75ns, SK hynix - 13,93ns).

 

Also there was few problems. After i installed SK hynix one of the module incorrectly identified in AIDA64 - missed half of model number (HMT41G). Crashed and don't responded TouchPad (re-boot didn't helped). Later i switched to Ramaxel to confirm that TouchPad didn't died and installed SK hynix again, but in diffirent slots and everything was normal. Don't know why this happened. Maybe because SK hynix modules a bit thight fit in slots.

 

I also try to find 2133 MHz module. But interesting thing... only Kingston have such product, but i didn't founded any information about JEDEC standard timings of DDR3-2133. Only DDR4-2133.

I have got few things to share:

 

1. I ask unclewebb (ThrottleStop Author) about problem with Lenovo Y500 - CPU throttling when GPU have got temp more then 52°C. He recommended next:

 

Quote

On some Lenovo laptops like my Y510P, Lenovo thought it would be a good idea to disable Intel Turbo Boost when the Nvidia GPU is active. It does not happen immediately. It just quietly happens in the background while gaming so users were not always aware that their CPU performance was taking a hit. The trick I use to fix this problem is I set the FIVR Non Turbo Ratio to 1. Problem solved. This eliminates this type of throttling.

mJy5VEF.png.09adb46d1a30a0e4e381ad13a1ae1054.png

 

But i told unclewebb, that have got Ivy Bridge CPU, so no FIVR option for me. He suggested another thing:

 

Quote

For Ivy Bridge, try clicking on the TRL button. I believe the Non Turbo Ratio setting is in that window. Try setting it to 1. If that does not work, you will need to use the Set Multiplier option. That should work. 

TRL.png.fd0aebfead6ab6c2647fce3cde736cd6.png

It's under "TRL" button in main menu.

 

I tested it and it working.

 

2. I tested two memory kits:

 

1. Kingston HyperX Impact HX318LS10IBK2/16 (2x8Gb, 2Rx8, DDR3L, 1866MHz, CL10);

2. G.Skill Ripjaws V F3-1866C11D-16GRSL (2x8Gb, 2Rx8, DDR3L, 1866MHz, CL11).

 

Kingston start normally, i tested speed and latency in AIDA64, but it can't pass MemTest86. One memory module have no errors, but second one have got 75+ errors(!). Each module was tested in same DIMM slot. I talk with seller and ask to test it in his laptop (Lenovo Z710). He sent me results - 0 errors! G.Skill at the same time have no errors in my laptop.

 

Each kit is DDR3L (low power) and backward compatible with DDR3. Each have got higher frequency (1866MHz) then maximum compatible with CPU (1600MHz). I don't know why Kingston act like this. Maybe because it's have Micron chips, when G.Skill have got SK hynix.

Yes it's fine, it's exactly what you need to do if you want the BIOS mod.

Depends on how far you overclock of course. And yes ThrottleStop is needed to run the i7 at full power but just be aware that it kicks out a substantially higher amount of heat, possibly to the point of overheating the CPU.

 

 

Cool, i managed to flash it successfully with the unlocked bios, but I tried to install hackintosh on it by meddling with the bios which eventually caused the bios unable to boot, however I restored the original bios with the USB stick and combo keys when the laptop first boot, so i now I am back to square one, which is the original locked v2.03 bios.

 

I wanted to flash it back with the unlocked bios, so I perform the usual fptw64.exe on win7 by backing up the original bios, and then use sl7 tool to modified the bios into unlocked bios. but now i encountered the problem saying the bios can't be written when I am in win7, so i boot to DOS, and run the PRR.exe in dos, and it stated as ready.

 

but when I use the fpt dos to flash the bios, it just give this error. (as shown in the picture) any idea what went wrong here?

thanks

So I have spent the last four hours scouring the internet trying to find the 2.02 update file as I have 1.05 and need to update to flash a modified BIOS. Turns out that the ONLY place to find it is in the file pack linked by OP, however obviously new users cannot download attachments without the whole five posts, approved by moderators, account promotion blah blah blah. In an attempt to save time, I tried to pay the six dollars for the Elite membership on the site so I could download it, but guess what? The page seems to be broken and I cannot add a new card to pay with. Can someone PLEASE PM me a link to the 2.02 update? I have the 2.04 but cannot use it without updating to 2.02 first. Please! Thank you so much!

Lenovo's original stock bios you can download from this link:  https://www.sendspace.com/file/e7wymz

 

Thank you so much man! Successfully updated from 1.05 to 2.02 then 2.04. I have my bootable disk ready, however I just realized that the package I downloaded did not include "y500-y400-sli-650m-80.07.27.00.33-oc.rom.zip". Is there any way you could PM me a link to that?

Is anybody able to use Wake On LAN from S5? Only when shutdown to S3 state the keyboard an mouse are working for waking up the Y500. When going to S4 or S5 sleep state keyboard mouse and networkcard are dead (seems without power). So no possibility to wake the laptopp. Waking is the only posible with On/Off switch. In the Bios i activated WOL. Any idea?

@MI19 Hi MI19, I have the same question with you. My laptop is y410p and I flashed the modded bios thanks to svl7. I found wake on lan config in the bios, but it seems has no effect. I can only wake from sleep state, unable to wake from hibernate and shutdown. When laptop sleep the network adapter's light remains blinking but goes off when hibernate or shutdown.

Does anybody have another download link? It seems kinda silly to me, that I have to be approved by a mod to download a file from 2013.

      Well everyone...I have a confession to make-I flashed svl7 modified 970m vbios before I wiped my drivers! Everything seemed to run fine, I could game but noticed my clocks fluctuating a bit crazy. Figured I'd try a OC profile in afterburner while running a 27 27 26 26 clock in TS a bit stupid I know. Well 3d mark froze so I did a reboot...Black Screen on startup I heard windows boot so I feared I bricked my card. Tried external monitor..works fine. This is where my stupidity really hit the cosmos. I had another m15x 900p LCD laying around plugged that in. Worked fine back too overclocking bro! Well same thing happened. My profile was not overly crazy as I can remember. But I bricked another screen. Plugged in external monitor everything fine. I was using latest nvidia drivers 436.48 I believe. So I wiped drivers using DDU. Reflashed to stock clevo bios. Tried both LCD again still nothing. Installed old 7970m still nothing. Cleared CMos again nope. Reinstalled 970m with svl7 vbios with newest driver and been gaming on my external monitor. Have done some OC with inspector. Everything seems to work as it should. Temps and performance are great. Did I brick my monitors??? Never heard of this problem.

      Hi guys, I am the proud owner of a Clevo p775dm3-g notebook purchased from azom.systems (authorized Clevo reseller in India, Model rebranded as Azom Legion-17.3 inches). Here are my specs:

      Core i7 7700 (non-K version): undervolted by 110 mv and turbo boost disabled in BIOS- machine uses prema mod BIOS.
      GTX 1080: undervolted by 100 mv on all frequency steps using MSI afterburner voltage/frequency curve editor. clocks are untouched.
      16 GB DDR4: Cant remember clocks.
      1440p 120 Hz screen: No tinkering done to refresh rate.

      CPU has been delidded and repaste has been done on both CPU/GPU dies with gallium based TIM-Coolaboratory liquid ultra if I recall correctly.

      My issue is GPU hitting max temp limit of 90 degrees while playing DOOM and framerate drops from 110 avg to mid 60s-70s with horrible stuttering- this is thermal throttling for sure.

      System was running beautifully after repaste at 86 degrees max/ 77 degrees average at 100 percent fan speed. A month later I decided to see how much further I could push the system and ended up undervolting the CPU/GPU and RAM even further. The RAM undervolting part didnt work as well as I'd hoped, and I ended up resetting the BIOS to undo everything and reapply the previous setting (-110 for CPU with turbo boost disabled.) 

      I noticed that immediately after BIOS reset, both my CPU and GPU temps were 5-10 degrees higher even with the undervolt/underclock applied. Also, I think the fans were a bit louder before I reset the BIOS which leads me to believe that for some reason the fans are now capped at 80% max fan speed. There doesnt seem to be a fan speed selector in the BIOS or anywhere else so I cant say for sure whether this is a fan related issue or something else.Before the reset I could override the BIOS setting and set the fans to 100% by pressing fn+1, could I have done something to that setting after resetting the BIOS ? I dont think I have damaged the CPU or GPU as temps are holding fairly steady at 90-91 degrees and laptop doesn't shut down while gaming.

      If I have overlooked something or if anyone reading this has any solution help would be greatly appreciated.
      All settings/drivers/windows version/app version are exactly the same before and after BIOS reset.
