# overclockSPD
Fast and easy ways to read and write data to RAM SPD. 
_\*will also include a gui for overclocking ram_

These are scripts that provide linux users with tools to easily modify data (timings, voltages, configuration...)
from multiple sticks of RAM. Other tools currently out there such as Taiphoon Burner, TB2BIN, RWEVERYTHING... only run on Windows. (which is unfortunate)

***It can also convert .emp files (created by Thaiphoon Burner) into .xmp files.***
  
  
Directly inspired by the man who created the amazing tb2bin tool: [Valuxin](http://forum.notebookreview.com/members/valuxin.400286/)

Shoutout to xx (or \x) from r/tp discord for helping me out. He is the man when it comes to RAM OC

WARNING: WRITING TO NON-DIMM LOCATIONS CAN CAUSE DAMAGE/BRICKS. HAVE CAUTION BEFORE WRITING ANY DATA THROUGH THE SMBUS
--------------------------------------------------

#### Install
###### You need to have ***i2c_dev***, ***i2c_i801*** and ***eeprom*** modules loaded. Also make sure the ***i2c-tools*** package is installed.
```
sudo pacman -S i2c-tools
sudo modprobe i2c_i801
sudo modprobe i2c_dev
```
Usually `i2c_i801` is loaded by default on Arch. It is included here incase it isn't for your distro.

### Usage

```
Usage: sudo ./readspd.sh [-x]xmp [-b busaddr] [-d dimaddr <0x##>]              # only reads 1 target at a time
       sudo ./writespd.sh [-x]xmponly [-b busaddr#] [-d dimaddr <0x##>] [FILE] # only writes 1 target at a time
       sudo python readspd.py -x -b <busaddr> -d <dimmaddr>                    # only reads 1 target at a time
       sudo python writespd.py -x -b <busaddr> -d <dimmaddr> -f <filepath>     # only writes 1 target at a time

```
Results will be saved in the current working directory. Check if there is write access to it otherwise the scripts will fail.

**Examples**
```
./readspd.sh -b 9 -d 0x50
./writespd.sh -b 9 -d 0x50 ./ocdumpprofile.spd
python readspd.py -b 9 -d 0x50
python writespd.py -b 9 -d 0x50 -f ./ocdumpprofile.spd
```
*OUTPUT*:
```
$ ls
dimm0x50.spd  dimm0x51.spd  dimm0x52.spd  dimm0x53.spd
```
