Planet Posted May 19, 2014 Share Posted May 19, 2014 TiN and I have been working on an open source project for flashing DDR3/DDR4 SPDs using a RaspberryPi. You can follow the project on xDevs.com as well as grab the code. TiN designed an awesome PCB for DDR3/DDR4 slots that connects up to the RaspberyPi and lets you flash your modules. This is the top of the board that TiN designed. And the back side of the board It has three switches for changing the address as well as LEDs to indicate which address is being used. He also included a header to connect the RaspberryPi as well as a power switch. He also added support for a MCU so eventually we can plug this via USB into a regular PC to flash. Here it is in action flashing DDR3 Quote Link to comment Share on other sites More sharing options...

TiN Posted May 19, 2014 Share Posted May 19, 2014 When will this be available and how much will it cost? Available - now, you can get all needed files from article here. Cost - 0 USD, FREE. It's build yourself educational project, I don't personally have plans to make it like a "ready-to-go kit" at this moment. Just did it for own needs on a free weekend, nothing more.

GENiEBEN Posted May 19, 2014 Share Posted May 19, 2014 Open source, that's how we like it. Looks like I got a new DIY to start and never finish Quote Link to comment Share on other sites More sharing options...
Crew Trouffman Posted May 19, 2014 Crew Share Posted May 19, 2014 Really love this kind of project ! Thanks for making it Open-Source too ! Quote Link to comment Share on other sites More sharing options...
TiN Posted May 19, 2014 Share Posted May 19, 2014 Btw, if anybody thinks it new and cool, let me refresh your memories Year 2010 DDR2 Ponyprog programmer from P5B Year 2005 Programming SPDs for DDR1 Winbond-BH5 Good ol direct access LPT port. Now we use linux to fiddle two pins on 100kHz. I barely call this "progress".. Looks like we will need supercomputer to fiddle LED in year 2020 Quote Link to comment Share on other sites More sharing options...

Crew Antinomy Posted May 20, 2014 Crew Share Posted May 20, 2014 Why not simply use R-W everything instead? Quote Link to comment Share on other sites More sharing options...
Planet Posted May 20, 2014 Author Share Posted May 20, 2014 Why not simply use R-W everything instead? Yes, in most cases you can as long as you have a working module with a board that supports R-W. However if you flashed a bad SPD to a module or your board isn't supported by R-W everything then what will you do. This makes it so you don't have to rely on a working system you can just use the RPI. Quote Link to comment Share on other sites More sharing options...
Crew Antinomy Posted May 20, 2014 Crew Share Posted May 20, 2014 Bad flash -> after POST press pause, stick in the bad module, boot to OS (the module isn't seen in system because it's after POST but it's connected to I2C). And flash it like it was there as usual. R-W knows Intel PCH (flashed with 6-th Gen chipsets, haven't run on newer ones yet). Quote Link to comment Share on other sites More sharing options...

TiN Posted May 20, 2014 Share Posted May 20, 2014 (edited) LGA2011's I2C ain't connected to PCH And barely lots of people will like to risk their precious hardware hotswapping memory modules But after all, there are multiple ways to do the job, either way. I'm a hw person, so I like do it hardware way. Others who are nice with coding do in software, like Taiphoon Burner for example. And normal people don't care about any of these Edited May 20, 2014 by TiN Quote Link to comment Share on other sites More sharing options...
Crew Antinomy Posted May 20, 2014 Crew Share Posted May 20, 2014 Well in your case I can believe that tracing a PCB, printing it, soldering SMD components and slots, assembling a wire with connectors, uploading OS to Raspberry and setting up the software is much easier than running a software utility. And normal people don't care about any of these Interesting news on LGA2011, thanks. I2C goes to MultiIO? Anyway, great work :celebration: Quote Link to comment Share on other sites More sharing options...
TiN Posted May 20, 2014 Share Posted May 20, 2014 Yes, specially when software utility just does not work It's no rocket science to solder 4 wires and two resistors and learn a little linux (this is what it needs actually to do for plain read/write I2C from RPI). Anyway, thanks. Updated an article with all STEP-by-STEP information of all software fiddles on RPI. Quote Link to comment Share on other sites More sharing options...
Bong313 Posted May 23, 2014 Share Posted May 23, 2014 nice work guys....I've made a nice experiment with BH5 chip and spd a few time ago (http://www.techarena.it/forum/overclock/8202-ddr-bh5-esperimenti-estremi.html) ps. my english isn't very good, sorry Quote Link to comment Share on other sites More sharing options...
