Bought RTX 3080 Laptop GPU for my P775TM1-G.

Glad you figured it out! I notice you have your RTX 3080 running at 180w. Did you shunt mod it?

Yes I did shunt mod it 🙂 I was quite conservative with it as I want it to last a good long time.

I added 20mOhm shunt resistors on top of the 5mOhm already on the card so in theory (without talking to the vrm itself) it should be 180w.

The performance is quite good and beats 165w dynamic boost cards in GPU benchmarks

Nice! I would suggest trying to talk with the VRM, because the power calculation usually is not so straight forward. I have been wanting to do this for long time but didn't touch my machine for almost a year lol. Now I have got another P775 I want to put together and I have regained interest in my machine.

 

Where did you get your 20mOhm shunt resistor? I want to replicate your mod as it seems to be safe.

 

Also, did you ever try to restore G-Sync functionality? This is something I want to try when I get my other machine fixed with my old 2080. Having two of the exact same machines and one with working G-Sync might make it a whole lot easier. There was someone who had restored G-Sync functionality so it should be possible, unless the drivers make it impossible nowadays. What are your thoughts on this?

I do plan on talking to the VRM at some point, I have recently moved countries so my time has been a little short and I've been using the laptop as my main PC now 🙂 

 

I salvaged The 20mOhm shunts from some parts donor boards I had laying around at the time, nothing too specific

 

I don't know if my machine ever supported gsync and haven't tried getting it working, using NVIDIA custom resolution settings I have the display overclocked happily to 100hz instead 🙂

Hi all!

 

Intel has updated most of their CPU microcodes including 9th gen CPU's.

 

For example my i9-9900KS has 0x100 microcode dated 2024-02-05.

 

Everything you need in order to update is your bios backup and UBU Tools (the archive will have updated microcodes in it).

Here is all 92 Pictures for those interested: https://files.fm/u/sjj9hyjue

 

 

Thanks for your guide.  I'll be trying your platform ID hack in future because I like the Drivers to install properly 😅.

 

I think I need to go back and add some 1.3mm pads to my inductors.  Do you have the pictures available for download again?  (If files.fm just needs to reset the bandwidth I can wait for that).

 

Project:

I got a great deal on a P750TM1 (I think it's really the same as P751) and I went for the 3080 over the 2080 because the price is only $50 difference.

I used TaoBao and SuperBuy to locate the Heatsink.  I think it was around $105 after shipping.

 

I have 2x styles of QTJ1, the bare die and the heatspreader one.  I am thinking I can make it work if I de-lid the one and put it under the contact frame of the other.  But then I need a copper slug to make up the difference in height.  (It's also a huge pain to get the contact frame held down on the one side, I'm using some threaded rod and 2 sets of bolts, I will need to clearance the underside of the heatsink for the bolts, and make sure the top bolt doesn't hit the heatpipe by using washers.) 

 

I have put that on the back burner until I get the GPU running properly.  For now since I sold the 8700k I am using a 9700F.  Kind of a lateral move, but it's OK.

Hi!

 

Can you explain to me how to use SuperBuy? If you need I can help you with the BIOS. I will reupload the images too at some point just have to find where they are. Would be so cool to buy stuff from TaoBao! I am from Europe. Latvia to be exact. Do you think it is possible? How much is the shipping costs approximately using SuperBuy? I need a new P775TM1 motherboard myself and I think they are cheaper on TaoBao. Much cheaper! 🙂 You can DM me if that is easier for you or add me on discord it is the same srs2236 🙂

This guide is pretty comprehensive.  Except sometimes with motherboards on step 4 you need to go into your 'Warehouse' and choose a "value added service", and pay them a little to remove the battery, otherwise it won't ship on an airplane.  (Also any accessories that are unnecessary, heavy or bulky can be removed to save shipping cost/weight.)

This is a P775TM motherboard:

This one needs a translator XD:

To California shipping is probably $20-40 (it varies).  Not sure Latvia.

any advantage to update the microcode on 9900k and 9900ks with the latest version, any update logs?

Not really. I am pretty sure microcode updates are only for security reasons. And even those are probably really niche. But I like to be on the latest stuff either way so that's why I update it for myself. But there might be something I haven't noticed I am not 100% sure but I doubt it.
