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.

Hi! I have a topic to start. I'm already happy with my og Xbox upgraded with another 64mb of ram, but I would love to have it modded with 1.4 Ghz Tualatin. My console inside is 1.0 revision motherboard and was manufactured in Hungary, it is also modded with dual tsop and xblast. Do you know if somebody is still doing that upgrade? I've already PM'd to N64 freak but I'am waiting for his reply, so meanwhile when I am waiting for that reply I decided to find out if there is someone else for that job besides of that, I've read that he is only doing 1 Ghz, not 1.4 Ghz anymore - but I already have two proper tualatins so maybe I'll convince him. The only other person I know that was doing this is Trusty but I don't know where could I contact him. My soldering skills are very little, that is why I'm looking for somebody.

Hello, fellow OGers! That thermal compound from the factory is failing in our beloved consoles. It can lead to rising temps and possible chip failure. It's s pretty straightforward process to replace it, and I've put together a tutorial video to help you out if you haven't done it yet. Enjoy, and please share any comments you have. Thanks!

So I was looking back at some of my modding info I have saved from the net over the years. With regards of cpu and gpu coolers, we have all put larger fans on the stock coolers and 80mm fan mods. when dealing with a slim mod the way to go used to be one of the slim cpu coolers and fans that were touted around for pentium 3 cpus. These are getting scarce and when you do see one they seem to be a pricey for my linking. Anyone have any combos from more modern stuff that works in a similar way. P4 reference fans look the right size but obviously the clamp situation would need to be looked at.

Would any you know if it would be possible to run a amd athlon thunderbird 1.4ghz inside the xbox? Its the rival to the pentium III with a socket A 462 could it be done. Could the cpu socket be modified to run this cpu? Any relevant information and ideas and thoughs would be welcome. No negative nancies , Keep those to yourself.

Hello OGXbox members. I recently found out that N64Freak no longer does the 1ghz mod, fair enough as the CPU is pretty hard to find on eBay HOWEVER!, I have found a 900mhz Mobile P3 CPU, it is the same socket as the Original Xbox uses Socket 495 BGA. This brings in the question if it is possible to do a CPU upgrade using this CPU as you can overclock on the Original Xbox and it can probably hit 1ghz. https://www.ebay.com.au/itm/Intel-Mobile-Pentium-III-SL59H-KC80526GY900256-900-Mhz-CPU/202303683276?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3D87f57bf1cc2a473697985d15daba2c95%26pid%3D100675%26rk%3D4%26rkt%3D15%26sd%3D283605646634%26itm%3D202303683276%26pmt%3D0%26noa%3D1%26pg%3D2481888&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3Aa1b681a6-db80-11e9-9263-74dbd180a9b6|parentrq%3A4dc979f116d0abc5a1275cceff9ade14|iid%3A1 By the pictures, it seems to be easy enough but should only be attempted by a professional, desolder the old CPU and heatgun the new one on.

Just trying to get a better read on my CPU for patching games. 1480 works on some but others are a bit more finicky.

Hi, I bought an upgraded xbox v1.0 board from Trusty years ago. It has 128mb ram and supposedly a 1ghz CPU yet in xbmc it only shows as 733 mhz. After searching for pictures of the original xbox CPU mine looks similar. Basically I want to know if this CPU is a standard xbox one or a different replacement one. Picture of my CPU:

does anyone on here know how to upgrade the cpu on a original xbox cause I would like to preform that mod but I do not know what to buy to do it.

What would it cost to get this done I’ve tryed looking no good

Following the footsteps of these gentlemen & crew: Trusty N64 Freak FriendTech I intend to upgrade the CPU in my Xbox, for Linux performance. At some point (after I have an SMD rework station) I intend to upgrade the RAM also. At this stage I'm just researching the feasibility, and seeing what I'm jumping into. I believe I can use a CPU socket (495) from a mobile Pentium 3 to use a P3 1 GHz "SL53s" with minor accommodations made. I will need to comb over the datasheets as I don't currently know If I can just "drop in" a faster 495 mobile celeron/P3, say after I've installed a CPU socket from an old laptop. Processors I've seen photos of installed in adapters include: SL5XL The Tualatin 1.4 GHz 512KB L2 Cache and 133MHz FSB SL53S Seen in N64 Freak's 1GHz mod, apparently using a cpu w/ 100MHz FSB is not out of the question. SL657 Seen in an adapter board somewhere. I wouldn't try an SL6BY because the core voltage is lower than 1.5V and the original CPU used up to 1.7V Some concerns I have: VID Voltage Range, VID[4:0] SSE Technology, SpeedStep Technology. GTL+ (do any of the cpus use the older GTL, if not then it is not a concern at the moment) Bus Speed: Can I use a chip with 100 MHz FSB? Nobody wants to downgrade.. L2 Cache: Does this matter? Can I simply use a chip with more, believe I can because Trusty & N64 freak have already done this without issue. To slow the CPU speed, they are apparently using STPCLK# assertion. This is accomplished on the adapter PCB with the necessary support components added. My first attempts will not include provisions to slow the performance, as playing games on the console will not be an immediate priority. I'll have to check the usual places and see if I can locate a CPU area schematic for the Xbox, I believe it is in the wild, if anyone has details, please PM me! The socket 370 to 495 adaptor shouldn't be too difficult to create seeing as how I have some datasheets to work from. First attempt I will use a standard 495 PGA mobile cpu (currently looking for one w/133 FSB) in a recovered 495 socket, then comes the task of designing an adapter board to go from 495 to 370. If N64 Freak would like to comment his words will be greatly appreciated, I'm not here to steal anyones thunder; just looking for a performance gain. I have datasheets from that era attached below, I'll have to see if the SL5sn (xbox) CPU is mentioned.
