cr4zyw3ld3r Posted April 8, 2020 Report Share Posted April 8, 2020 Hello, Newb here has anyone ever used this? https://web.archive.org/web/20090821174402/http://www.xboxisozone.com/downloads/614/cpu-multiplier-unlocker-(overclock-xbox-cpu).html According to the forums here https://forums.afterdawn.com/threads/overclock-xbox-cpu-1200mhz.700905/ It was possible to modify CPU speed. I have a hard time believing this since all the mods I have seen on this recently have involved a TSOP flash. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted April 8, 2020 Report Share Posted April 8, 2020 Did you see the date it was posted 2009 if it was a working mod there would be a lot more info about it. Cheers SS Dave Soft modding is like masturbating, It get's the job done but it's nothing like the real thing. Quote Link to comment Share on other sites More sharing options...
samspin Posted April 8, 2020 Report Share Posted April 8, 2020 I am extremely sceptical such a thing has ever existed. Overclocking needs to be set at a very low level before even the Kernel is started. Further down on that archived page a comment states: "so i downloaded this and can confirm it has a 3dmark06 keygenerator, not as described, why have the comments that told people not to download been taking down this is not as described." It sounds more like the uploader was disgusing a means to pirate software as an Xbox overclock tool. Even if that comment wasn't there, I wouldn't believe it. The serial number of the Xbox is stored in a separate EEPROM. XbOverclock does not require the serial number of the Xbox to work, it directly modifies the BIOS for flashing to TSOP, which is otherwise identical across many Xboxes, and no serial number is stored there.

Here is hoping Kekule is successful with his 1.4Ghz PIII interposer so we can start dropping some faster CPUs into the box. Don't know that I want to go through all the BIOS mods to push the stock CPU for marginal gains. Quote Link to comment Share on other sites More sharing options...
samspin Posted April 9, 2020 Report Share Posted April 9, 2020 I will tell you now from personal experience: some games simply do not like being run on higher than stock clock speeds. Some are highly timing dependent in order to present animations in the correct order, some can be skipped entirely in my experience even when running a slight overclock at 740mhz- even with a patch. You can patch your .xbe files with the new clock speed and this can increase compatbility somewhat, but it doesn't work for all games. Notably Rockstar games seriously suffer from this issue- I found GTA 3 to be impossible to start due to the camera angles being incorrectly set, even after watching the severely messed up cutscenes. Even if you copy a savefile from a stock speed Xbox, you will find that time-limit based missions will count down faster, with traffic on the road going faster and therefore getting in your way more- essentially making it almost unplayable. It's worth keeping two Xboxes around- one for stock speeds, one with an overclock (or CPU mod). That way you get the best of both worlds- on some games that can handle the higher clocked speed you get a noticable reduction in lag when using it as a host for LAN games. If you do want to try running time-sensitive based games on an overclocked Xbox, make sure you backup your XBEs and patch them with XBEpatcher with the new clock rate (which can be found by viewing System Info in XBMC4Xbox). https://www.ogxbox.com/forums/applications/core/interface/file/attachment.php?id=2805 This works for some games but not all of them, as noted above. In my opinion: a great combo is a 1.4ghz Xbox with an overclock for both the GPU and CPU. Really great for homebrew! I note that you mention Kekule is making an interposer for dropping in 1.4ghz PIII CPUs. This has been done before, and even if it is successful you still need someone with access to the equipment and skills neccessary to fit such an interposer. Generally the people who gain the knowledge to do this spend a lot of time and money doing this, and realistically do have to charge accordingly to make it worthwhile. This is the likely reason only a few people in the world actually are willing to pull off such a mod, let alone give out the knowledge they spent a lot of personal time and money to discover. BGA soldering is no easy feat! I long for a day when BGA soldering is made easier for home users, making repairing today's tech a lot more viable as well as keeping older equipment upgradable for longer. But I'm probably wishing for a mountain there. Quote Link to comment Share on other sites More sharing options...
SS_Dave Posted April 9, 2020 Report Share Posted April 9, 2020 With the rate this is taking getting 1.4Ghz PIII CPU's that work is going to be a stumbling block.

But I'm probably wishing for a mountain there. Yes the mod in question will require a pro with a rework station. However the Trusty and DreamX boxes are damn near impossible to find today and N64freak seems no longer does 1.4Ghz mods only 1Ghz and even then often times he declines to do the mod. So having another avenue to go down with this will be ideal even if costly initially. I would really to have this as a dev box with my "stock" console for playing games and the CPU/ram modded one for testing etc. Quote Link to comment Share on other sites More sharing options...
