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.

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.

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.

      Hey allI, I need help  with modding my BIOS. I was wondering if anyone could help me mod my BIOS to unlock the 'Advanced' tab which I don't have on my InsydeH20 F.52 Rev 5.0 Bios? Thanks so much and I look forward to your response! Laptop: HP Pavilion x360  ba109tx

      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.

      Hey guys, I have an Alienware m14x R2, and I have been trying to get access to the BIOS so that I can change the boot options (Everything is locked, I am unsure if someone set a password of if these are locked by default).I've tried updating the BIOS, and resetting the CMOS and nothing has changed this. Would anyone know if there are other options I can explore? Thank you.

      In this thread you can post your requests for Lenovo ThinkPad X250, X260.
      If someone wants upgrade Wi-Fi card and remove whitelist, or unlock hidden additional menus and settings in bios setup menu, then you can post your request in this thread.
      Important!
      For creating your personal bios dump and to flash your bios mod, you must use any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip!
       
      Just dump your Bios using any SPI programmer  (like CH341A programmer) and a SOIC8/SOP8 test clip, then post it in this thread or upload it to any fileserver and send me the link.

      Each bios mod prepare personally and based on your personal bios dump which contain your personal data like Serial numbers, UUID, Service TAG, MAC addresses, Windows keys, NVRAM settings, etc.
