Trusty - just another daft question... the Micro-architecture of the Pentium M is very similar to the Tualatin, would this ever work?

Are you still developing more upgrades or is this as far as the Xbox will go?

Hi,Geeba, because of the limitation of the XBOX board north bridge , the P3-S 1.4G is the maximum upgrade by now....
Regards! Trusty

After running a game and before doing any changes to the box I have I figure I wanted to see what the temperature is for the CPU when running with a load (watched a movie and I see the CPU gets to about 75C and not any higher with the fan running 100%.

I plan on doing the following:

I'll do the 80mm fan mod to replace the stock fan as it runs quite loud at 100%

I'll shave off the fins on the heat sink to the desire high recommend by trusty which is 13mm.

I will also cut the wire frame in the back as Nextelhalo suggested so that the fan is able to exhaust more air.

As for a fan on top of the CPU heat sink I manage to take out a 40mmx20mm fan out of an old computer that no longer works and I know the fan still works.

Trusty what type of thermal adhesive did you use for the contact between the heat sink and CPU?

Looking for also any other suggestions or recommendations I can do to lower the temperatures. From what I understand normal conditions the CPU should be between 40 - 65C.

Hi imgwpt0204,

No need special thermal paste for the CPU, but if you like , you can use the one with silver inside..

Regards!
Trusty

Iv managed to get my 1.4ghz box to never go above 60C (even when emulating stuff that wouldnt work on a stock box) and idle at 56C in xbmc (with the GPU never going above 32C)

I have an iceberq fan on the cpu, and i have removed the DVD drive. I use a 2.5 inch HDD mounted in a 2.5 to 3.5 inch adapter in a frame made from the top of the HDD frame stuck to the bottom of the DVD frame. (The 2.5 inch HDD creates less heat, which is important as it is above the GPU). I also have the permanent 100% fan mod.

I stuck the front part of the DVD tray back into the case (with holes drilled in it) and drilled some small holes on the right side of the case to match.

I also attached a piece of plastic to the lid that slots between the motherboard and the power board, creating better airflow and keeping the hot air away from the CPU

It is noisy but id rather that, and have the peace of mind knowing I can play my 1.4ghz box with no worries about it overheating

Started working on my efforts on cooling the CPU. I have a 80mm fan on the way.

Took a look at underneath the heat sink and noticed the thermal paste was smudge all over the place on the CPU and on the bottom of the heat sink. I believe the best thing to do would be to remove and reapply the paste to give the heat sink and CPU better contact and increase cooling off the CPU.

Trusty did you mean Arctic Silver 5 from this website? http://www.arcticsilver.com/as5.htm

Bunghole you mention using an iceberg fan on the CPU. What power source did you attach the fan to?

Yes,imgwpt0204,something like that..

I've managed to get my Trusty 1.4 upgrade to never go about 125F / 95F, even under load. Usually sits idle at 110F / 85F.

Darth,

That's incredible!

What is your secret?

I'm still in the process of fixing up mine and would love to hear on how you got yours so low.

Hi,

Well, I have two Trusty upgrades. I use both for emulation - one is setup on the HDTV, mainly for my gf and I to watch shows via the network and the other is hooked up to an old Sony PVM monitor for arcade stuff only.

The HD Trusty is in a custom case, called the Xport Xpod. Here is a review from years back:

http://forums.xbox-scene.com/lofiversion/i...hp/t254955.html

I had the case for years and it was actually pretty horrible for cooling, which I never realized. I found this out pretty quick when my new Trusty Xbox would power off when it got to hot! I found some posts on X-S about how to help by cutting out the grills for the fans - which I opened completely. Here is the post were people were talking about it:

http://forums.xbox-scene.com/index.php?s=&...t&p=1909275

I have 3x 80mm fans on this case - 1 intakes air from the left, 1 pushes air out the back (where the stock fan usually is right behind the CPU) and the final sits right on top of the CPU heatsink. I had to cut out the acrylic and move the HDD to get this to work. I then cut a hole in the top of the case, right above the fan, to allow cool air to be sucked in.

I also replaced the heatsink with a copper one, which I cut down myself to fit. That was a pain. Cutting copper is NOT easy. However, using this new heatsink dropped the temps by about 15 degrees F. The temps also seemed to be more stable - ie: they don't seem to ever spike. Trusty knows about these results, but he pointed out that using copper is much more expensive and much heavier. Also, based on the reduction in temperature, it just isn't worth it - which I totally agree with. Intel P3s are VERY tough and can take the standard temps no problem. Mainly I did this because it looks cool and I wanted to push the cooling for fun.

I also replaced the GPU heatsink with a tall aluminum northbridge one. I've been doing this with v1.0 xboxes forever because it gets rid of that little fan.

TEMPS > 125F / 95F under load, 110F / 85F - idle

For the Arcade Trusty, I used a red XCM case. Now, since I wouldn't have room for a big 80mm fan on top of the GPU in the standard setup, I decided to ditch the DVD drive. This enabled me to have 2 big 80mm fans. The layout is pretty much as follows:

- The HDD is where the DVD usually goes
- 80 mm fan acts as an exhaust behind the CPU
- 80 mm fan was inserted above the CPU heatsink - I cut a space for it out of that plastic HDD tray
- Custom copper heatsink
- Aluminum tall northbridge heatsink for the GPU (I also use one of the little GPU fans on top of this)

The last step was to remove the XBOX jewel on the top and cut a hole there to allow air to be pulled in. A friend of mine then sent me a clear jewel that could be popped on there when its not in use.

TEMPS > 118F / 106F under load, 110F / 100F - idle

I do need to test the temps more under strain, especially for the Arcade Trusty, but so far, this is what I've been seeing. Last night I was playing CoinOps for an hour or so and those were my results.

Hope this helps. I'll post that heatsink model I cut down when I hear back from my friend. He was the one who actually came up with the idea and found the right heatsink. (He also has a Trusty) I'll take some picts eventually and post them here.

Talk soon

I think P3-S 1.53G is the maximum upgrade
http://www.mysilu.com/data/attachment/foru...tttj5e5ra63.jpg

I hope you use Mobile Tualatin, because P3-S noise， power ， cpu cooling

Darth,

Sounds like a lot of work that you have done on both trusty xboxes and the cooling paid off big time. Congrats. I think however 3 fans is a bit excessive. Either way nice job on the cooling.


Looking forward to seeing the pics when you have time.

Well, one may say excessive - I say cautious.

That GPU can get very hot and you can see that in the one Box I have, it never breaks the 100 F mark. The other hits around 110 F but that's acceptable. If the GPU died (heat kills) the mobo would be essential useless. I want these to last a while, so I'd rather overdo it a bit.



I think Trusty said the 1.4 was the max, but you'd have to ask him.

Can anyone tell me where to buy the 1.4ghz CPU ? I have like 4 xboxes that I would like to upgrade also I have 1 dead xbox and I was wondering can I remove the ram chips and use the on working xboxes??

Thanks

I think trusty is the only one doing the upgrades. The xbox celeron chip is a bga chip directly soldered to the mobo. It's not in a socket like a pc processor. You need special equipment to unsolder such a chip without damage. I also think he uses a custom made socket for the new cpu, as it's not fully pin compatible.

Considering the ram chips. I read somewhere that the 1.6 mobo ramchips have worse timing parameters than the others. If your mobo isn't a 1.6, you should be able to use the ram's.

regards.

Trusty still doing this upgrade?

IS it a P3 or a Celeron?

I want one - I bought a 1GHZ from you a few years back.

yep,
he still does them and he is using a P3

Did anyone ever experience problems with starting a game at all?

I tried getting GTA SA to work, but it doesn´t even start, neither from HDD nor from DVD, not matter if it´s patched for 1.4 g and 128 RAM or not.

The console simply reboots, I also tried it with the X3 turned off, so that it uses the X2 Bios on the TSOP, but still, it simply reboots....

everything else works fine BTW (the GTA disc also works, tried it on another console...)

any suggestions are welcome
-Toby

Hi,
first off, is there no EDIT Button here or did I just not find it?!

the Problem appears to be solved, it had nothing to do with the CPU mod, it actually had to do with GTA PAL Copies not working on NTSC Systems due to region protection.....
Sorry for derailing the thread a bit.

-Toby

hey trusty, how much you want for one of these boards shipped to US zip code 98270?

Hi .MasterGouken,

PM sent...

whoa im away from the scene for a year and all this happens.. now i want a premodded board too..

Trusty would you be os kind as to send me the price info shipping to Spain and or Mexico?

Hi,eetu,PM was sent,sorry for the delay...Regards!Trusty

Hey trusty how much for 1 to VT U.S.A. I'm interested.

Hi,sethro454,PM was sent,sorry for the delay...Regards!Trusty

Very interested in the topic of the possibility of installing a faster processor.
It is a pity that the pictures in the beginning has not been preserved. Would love to see them ... In order to understand how to do this and attempt to repeat yourself.
would be very grateful if they were either re-posted or sent to me by email nepomnyahix81@gmail.com

Hi Trusty excellent work . Can you PM me for a price quote to Cyprus?
BTW, Can i send you my board? or not?

Thanks

Hello Trusty I am interested, can you PM me for a price for upgrade to 128 ram , can i send you my motherboard?

Received my board yesterday, tried it out today and it boots up fine, Linux detects the RAM. Going to try it with Emulators & Linux this weekend so I'll post results, but I can already see that the hardware is very well done!

Great work trusty

This is amazing. Just unpacked my old Xbox, and there's still people keeping the scene alive.

Trusty, I have a 1.0 board, if I want to get it upgraded, what's the best way? Send you my box, or order a new 1.4/128 board from you?

@DarthMingus

Have you had any luck identifying the copper heatsink model that you used? Sounds like some great cooling, id love to have it in my box...

Hello,

Firstly congratulation for this project, it seems a lot of persons are still in love of the first xbox and all its wonderfull abilities.

I would like to get my so loved xbox 1st generation be upgraded with higher cpu/mem.
Knowing I am living in France, Paris,
What is your suggestion :
Send you my box, or order a new 1.4/128 board from you?
What is the price in each case ?
If you send me a new MB, Does my current and original xbox case will fit it ?

Cheers,

Hi,

I sent you a PM about this, but just so others know as well, here you go:

Supermicro SNK-P0002

http://www.provantage.com/supermicro-snk-p0002~7SUPM0QK.htm

To get it to fix, I had to cut off the two sides with a hacksaw and then use a dremel to fashion it to mimic Trusty's original heatsink design. Its not that hard, it just takes patience.

Good luck!

Hey Trusty, would you ship a pre-modded board to Brazil?
How much would it cost?

hey, can you guide me to do this myself ? thanks

If you need a guide, then you can't do it yourself.

i just need a guide, i'll do it for fun mate

Hi,ubernewb,,PM sent..sorry for the delay...Regards!Trusty

hey trusty, u still do this upgrade ?
as i read on another topic, a guy said u discontinued that upgrade ?

I'm from VN and can u send me the adapter only ?

He told me he discontinued the 1ghz upgrade. Now he only does the 1.4ghz

Hello,hlmasterchief93,I am still doing the upgrade..
It's not available to sell only the adaptor..I am sorry..

Regards!
Trusty

Hey Trusty, I had PM'd you about the adapter and got your reply that you can't sell adapter alone.

Do you still do the mod though? For upgrading a 1.4 board to 1.4g/128mb RAM what would the price be from USA?

Is it possible to switch between 1.4GHz and lower speed once the new processor is installed? Was reading your thread from back in 2007 and there were issues with some games running too fast - is that still a problem or is that fixed now?

Trying to decide if this mod is worth the money if I'm mainly going to use my Xbox for emulation...

Thanks!!

Hello trusty,

I was curious if you still were selling pre-modded systems. If so how much for one shipped to US-77048?
Tried to PM you but it seems as if you PM's are full.

Trusty PM me too if you have any boards 1.4/128 for sale.
In the market for one.

Thanks

Hi Trusty!
I want to buy one of your amazing board. How much its cost? and if it is possible to send this to irleand.. Please Pm me
Regards

Trusty, PM and Email sent.

Hi,jrlepage,

Yes, still doing the upgrade.. for the price,please see the PM..
Sorry for there is no switch for the CPU speed change..
For some games run faster,you can use the 1.4G patcher.

Regards!
Trusty


Hi, Wicked,

please see the PM,,
sorry the delay..
