Answered ignore.

At the risk of sounding dumb I have a question, Is there a reason there is no 6400mhz SODIMM ram? You're able to purchase it on soldered models like a Thinkbook 16p Gen3 etc, is there any plans to bring it to SODIMM form factor or am I missing something?? Is it just not out yet or are they not manufacturing it?

You have to do it in the RAM States, the lower 3 states (power saving) are set to Gear Mode 2 and the final 4th state (under load) switches to Gear Mode 1. The ONLY way i was able to lock it Gear Mode 1 was to set all 4 RAM states to Gear Mode 1. I will post a screenshot of this when I have access to my laptop again.

Hey! Sorry for the late reply, With tuning you can get the i7 to the same specs as the i9 i've got mine getting higher benchmarks than the stock i9 so id suggest having a good play with XTU! Especially undervolting CPU and GPU. Glad you sorted it out, There is a new BIOS out for this model that I havent tried yet, I'm still on C44W.

I recently got the Legion 7i 16ITHg6 and am genuinely blown away by its power, however I was very un-impressed with the ram situation as I found the performance pretty unacceptable for the price of the laptop. Before even receiving the laptop I purchased the G.SKILL RipJaws Series 32gb (2x16GB) 3200mhz CL18 DDR4 F4-3200C18D-32GRS kit to replace the stock Samsung DDR4 3200 CL22 RAM. I read around for a while on unlocking the mythical advanced bios, tried all key combinations read every post watched every youtube I could find, all to no avail, it only worked on earlier models was the consensus. Then a random god send on the Lenovo forum sent me a link to a windows app that one click unlocks your advanced BIOS for most Lenovo laptops, within a minute I was into the advanced BIOS and boy are there a lot of options there! Including enabling XMP! https://www.win-raid.com/t9926f16-TOOL-Lenovo-H-Bios-Unlocker-and-Locker.html I hope this helps anyone else as it was driving me nuts having performance sitting on the table and not being able to use it. EDIT: I have since changed RAM to Gear Mode 1 for better latency, 83.9ns down to 64ns and +2/3% read write speeds. After using the one click BIOS unlocker for Windows the Advanced menu is available. Finally having XMP settings and many many more manual settings (I ended up selecting manual everything) The Stock Samsung DDR4 3200 @ CL22 RAM that came with the laptop - SLOW (Take note I updated BIOS and slightly different overclock from here on, it was unrelated and does not effect scores) The new G.SKILL 3200 CL18 RAM with basic BIOS and default settings, laptop only allows it to run CL22+ with basic BIOS. XMP Enabled with CL18 on the advanced BIOS! - FAST HWInfo64 Report.

My RX580 Sapphire Nitro+ with Custom VBIOS, can still squeeze a bit more out of the core, still working on it. 100% stable at these core/mem/voltage values, I have managed a hefty memory overclock with custom timing straps. This result is apparently number 8 for RX580's on 3dmark benchmarks. I have hit a 2750 Superposition score before but it was not really stable or consistent, so I dont really count it. GPU: Sapphire Nitro+ RX580 Core: 1480Mhz Mem: 2350 + Custom Timings Max Temp: 65C w Custom Fan Curve I will bench this card again on one of my better systems to see if i can squeeze a few more fps out and when I have more time.

Hmm def not mobo then, could be something to do with the polyfuses (or whatever the PSU equivalent is) needing time to reset once OCP or a short is caused by the fault.

I had a similar issue with ASUS Anti Surge being over sensitive and would not allow me to reboot without doing this PSU resting. Your BIOS update may have had some change made to the Anti Surge. I'm now having a similar issue on my Asrock board, and i'm using high quality Corsair HX1000i PSU's.

What motherboard are you using?

@jonnyGURU Ok I switched it to Single rail mode, shut down windows, booted to SMOS on USB also added -gser 3 to Claymore 10.4, unfortunately still no dice, shut down in the same point. Testing Windows 10 again now with the Single rail mode.

Ahh i see, I was looking for an option to switch off the OCP but couldnt find it, so switching it to single rail mode is what does it? I'm not sure how I would do that for using Linux SMOS, does the corsair link software actually change the hardware state permanently to single rail? Or only when the Windows OS Boots? EDIT: @jonnyGURU Actually I just stumbled upon a post that said it is saved to the PSU, then i read who wrote it.... and it's you again on another forum haha.

It reports "Event ID 41" which from memory is just powered off without clean shutdown. I was giving Simple Mining OS a go yesterday for performance comparison, and funnily enough it recreates the problem, but this time at the exact same point of Claymore loading, when the DAG Buffer is being created on the GPU's it cuts out every single time, in Windows 10 version of Claymore it passes this part no problem, and has never cut out there. My undervolt/overclock is very stable and has never reported an error or crashed yet, I tried putting everything back to stock clocks and it also did the same thing. EDIT: I've just found this option in claymore which may alleviate the power spike, -lidag low intensity mode for DAG generation, it can help with OC or weak PSU. Supported values are 0, 1, 2, 3, more value means lower intensity. Example: "-lidag 1".

@Stefan Payne I switched them all to PCI-e but unfortunately that has not resolved the issue

@Stefan PayneHmm not that I didn't believe you, I just had my 4 working rigs here, all with cold cables, so I did not have a reason to think otherwise, maybe I have just been lucky. I'll try switching them over to PCI-e and see how I go, appreciate the suggestion.

@Stefan Payne I have those risers running flawlessly on 4 other rigs, using Server PSU's, since these cards are under-volted to 100 - 110w the cables are not warm to the touch.
