PS4 12volt Mod. for bigger HDD´s
youtube.com/watch?v=M2E6-hxmb0Q
PS3 SSD vs Raptor HDD
youtube.com/watch?v=anM21V36afk&t=1211s
PS3 Max. Storage Capacity is 2Tb
Bigger SSD´s have also more DRAM
VelicoRaptor 1Tb 64Mb cache is a killer HDD's witch last 4 ever 😅
My Favourite are the Crucial SSD's, as they got mostly 2x dram cache, working like dual channel...
Crucial Mx500 2Tb 2x 1024mb dram
(very expensive still)
Crucial Bx100 1Tb 2x 512mb dram
Crucial Bx100 512Mb 1x 522mb dram
Samsung EVO 850 2Tb 1x2048mb dram
Samsung EVO 860 2Tb 1x2048mb dram
Samsung EVO 870 2Tb 1x2048mb dram
Samsung QVO 870 2Tb 1x2048mb dram

![PS3 Undervolting is a MUST!!! (Sherwood Syscon) + Power Consumption & Temps Test By:NSC
Hi Guys :)
Just for you to understand, normally the CELL/RSX runs with about 1.20-1.30volts, it depends the PS3 Model, condition from the NecTokins, your multimeter and stuff like that.
Me and other people proved that the standard voltage is just to high and not really need because it causes extremly overheating problems and this is just unnecessary...
With other words, your PS3 is able to run also with lower voltage and also way cooler, this made my PS3 running about min. 10°C Cooler and the fan speed got lower too!
For that Mod. you will need to get connected to the PS3 Syscon, please watch this video first for more Info:
https://youtu.be/ZvqJQVd5pBY?si=2hud4_ydjSgR84L1
For the syscon reader adapter Google:
UART FT232RL or PS3 UART FT232RL
New Syscon Reader package:

How to prepare your Syscon reader:

Here you can download the ViD tables for Sherwood and Mullion Syscon:

Command codes for Sherwood Syscon:
Read CELL: r 50 01
Read RSX : r 51 01
Write to CELL: w 50 [your value]
Write to RSX : w 51 [your value]
Check Checksum:
eepcsum
If you have the same model like in this Video, CECH-250x you can probably try my settings:
CELL 0.86250v [75] Very stable is 1.12500v [4B]
RSX 0.84375v [78] Very stable is 0.86250 [75]
To be very sure without testing around just set the CELL to 1.12500v [4B] and RSX to 0.86250v [75] Should work fine.
On the PS3 Slim CECH-200x models you can go directly to 1.12500v [4B] for the CELL and 0.9000v on the RSX [6F]
On the Super Slim you can go directly 1.12500v [4B] for the CELL and RSX to 0.86250v [75] Should work fine.
All this voltages was tested on normal Firmwares (CFWs) without overclock
DO NOT INSTALL OC CFWs if you undervolting!!!
Dont forget to fix the checksum after every change, address on sherwood syscon is:
7fe Just do it like i show in the video.
w 7fe [fixed checksum]
Get your PS3 Delided and Undervolt it, this is the best of the best for your Baby!
