how be sure that the mods are correctly done ?
i ve always 1.82 Vcca with the pot set to 3.2 3.3 kohm
looks good, but you might want to tack down the wires going to the pot
yeh, they come off all too easily..Quote:

yes, you are corrrect multi 8 on desktop boards does not work, and multi 6x works as 7x or it is vice versa I do not recall... :)
i have modded mine yesterday
my small celeron-m rans now better
C-M380 @ default vcore 2620Mhz ;)
i need my 780ES back to make better scores ;)
i think having a problem :/
first boot with 780 es with 1.86 vcore 1.85 Vcca under cascade, some pi and other bench , and i try maxscreen @ 3845 but crashing
this the crash i have problem , cpu won t boot :o
i decided looking at the cpu and the CT , and i see a little water on the CT479
so i decided to clean the CT and verifie the Vcca
but the vcca start around 1.2 and go up to around 2.5 Vcca in one minute
what can be the problem ? since yesterday ?
edit : i ve seen that the 47/16 wasnt sold
but i cant sod on the point :/
is that ok ?

Wasn't there talk from Hipro5 of even more mods for the adaptor? I'd really like to know what they are before I sell up - one last blast on the old PM front :D
:D
the harder mod for me is in the screen upside
If the VCCA fluctuates, I would first look at the resistor (or the soldering). You could take it off to measure it. If the value is good, solder it back on and see if you get a stable VCCA.
after modding on an other point , the Vcca is stable :)

this burned thing is a bidirectional non-latched translator from Siemens.
Any ideas where to get one? :D
It burend when I was running the Cm at 191 mhz FSB on air :rolleyes:
rebuy a CT :p
This is a very lengthy thread. Would it be possible to consolidate on one post all the mods and a shopping list from someone that has done all the mods?
So, in this pic, the only thing added was the black tantalum cap?
http://www.thelab.gr/images/Hipro5/D...dded_2_jpg.jpg
Have a look at page 20
There is a picture with a discription of the mod
http://112233445566.free.fr/Vmods/CT...t479%20003.jpg
GREEN = 100µf/16v
BLUE = 22µf/10v
YELLOW = pot 5k set to 3.3K for Vcca (1.5 stock , and 1.85 with pot set to 3.3k)
RED = 14µf/25V
and here is the 47µf/16v

one of my more recent posts in this thread shows what is added and where on the upper side of the adapter.Quote:

Isn't that because one uses an inline resistance and the other a variable resistance? The inline is soldered over the existing one, and the the VR has to be grounded.Quote:

Doesnt matter if you solder it the way hipro showed it, or the other way. Both methods have a connection to ground.
I did not have the adapter in hand when I asked him to confirm the solder points. After some testing with my multimeter, it doesnt matter which points you solder to. The way hipro did or cirthix. The points are all tied together. the ends of those resistors are connected with a board trace which is why you can solder to one or both of them, and the back end of the top resistor is connected to ground. So doesnt matter which resistor you solder to (one or both), or which ground you use. In fact, you could prob solder to various other places and get the same result...but I have not checked that out yet. Typically when I find I am soldering in a tight spot I look for alternative spots to solder to. I should have done that today when doing the mod. I popped one of the SMD resistors off the board by mistake. No matter, I will replace it with another one and keep rocking. ;)
I'm here to learn, and was asking to be corrected :p:Quote:

[hijack]
Resistors, or any electronic component, do not have to be directly connected to ground on either side. Sometimes resistors have current entering one terminal, and the other terminal is connected to a capacitor/LED/diode/Vreg/ect.
You should never assume that one terminal of a component is always connected to ground. Always test it first.
As for why one pin is ground and the others are not, thats totally arbitrary. There must be a ground reference obviously, but why they chose the end pins is because it simply suited the overall circuit design. If you test the pin adjacent to the one cirthix marked as ground, you will see that it is not a ground reference. What I am getting at is always check both terminals before assuming one has to be a ground.
[/hijack]
There are two reasons to use my solder point instead of hippro's, but both do the same exact thing(both points are grounds).
1: you only have to solder to one end of the surface mount resistor, making the chances of you accidentally removing it much lower.
2: the pin is much larger than the resistor and is much easier/faster to solder
I had to use an alternate point because i pulled the wires when i was messing with the heatsink and pulled up the solder point.
sorry for the confusion
No confusion after I got the component. I just wanted clarification why you used other solder points.
I agree, better to use other points if possible. Like I said, I popped one of the SMD resistors and had to replace it.
This thread is great! I have a question for the stateside people who have the CT-479 adaptor, where do we order these caps from? My local surplus electronics store does not carry these, and all my googling leads me to stores in Europe. I have an extra CT-479, PM750, P4C800-EDLX, and 2 x 1gb DDR-500 just sitting on my desk.
And while we're at is, does anyone know when Hippro5 will get around to releasing the rest of the mods?
We'll just have to wait, have sent a polite PM and he's usually good about these things so it's a case of, "in his own time".
I think I destroyed the resistor for the vcca mod. I touched the soldering iron way too long to the resistor...multiple times >_<. Now im getting just a little over 1v on the jumper measure point, that is the same voltage which you'll get without the resistor right? I fixed it with a little pencil mod over the resistor (i have 1.6V VCCA now), I wont be able to fix it till i get my new soldering iron though, the one i have now is really bad quality and has a rather big tip :(

Or if there really is, we must wait till hipro5 will get his yonah and mobo.
Maybe then the rest of us will enjoy clocking legacy hardware :P
Patience my friend. I think Hipro gave us all he had. If not, there may have been a reason. He may have been working on another mod that didn't work out. I know I learned a hell of a lot from reading his threads. My only problem is that he's too far away from me to shake his hand and say Thank you!;)Quote:

This is a simple one.....ADD a 50 Ohms or 56 Ohms resistor onto each existing one......The onboard are 56 Ohms.....This helps when we overclock with higher than 1.55VCore to eliminate the Vdrop due to current drawing, onto two pins of the adapter feeding by those two resistors....
http://www.thelab.gr/images/Hipro5/D...VCore2_jpg.jpg
Vchip mod
Solder a 10KOhms 25 turns trimmer onto this capacitor to ground and trimm it so as to accive about 3.7 - 3.75Volts onto onboard chips......Before power up, trimm it at it's MAX value(10KOhms) and then solder it.....This helps the stability and "presses" a bit the onboard chips so as to handle the "load" and the "fast switchings" better.....

could u post that mod in one piece here? it's really hard to get it straight when it has so many parts. 23 pages!
I just got my hipro5 kit in the mail today, will be modding the adapter tonight.
What's this so-called 200FSB barrier everyone talks about? I'm able to run 207x13, 240x11, 265x10 just fine (via clockgen) on my PM750. For boot-up however it likes around 225 or so, but that's still past this "barrier."
I just wish I had PCI-E :(
Fastest SPI so far for me is 28secs with a modded P4C800EDLX with 1023 Bios.
The V-chip resistor should be a 15k Ohm pot or more, I used a 10k Ohm one and got 3.92V .
I think I'm doing something wrong, just finished all the mods and my 750 doesn't clock any better than it did before, will be trying a different motherboard tonight.
same hereQuote:

Quick question do those tiny capacitors have a + and - Side like alumium caps ?
Or can I install them any way and not worry about + or _
the ceramic caps in the mod (the small surface mount ones) are nonpolarQuote:

Hipro5, on the chip mod using in a 10kOhms resistor gets me 4v on the chip, is this too high? I notice that trimming down the VR increases voltage so is a bigger needed for can I get away with it?Quote:

will do :up:
Hipro, a question for the Legend. On fully modded adapter one of added smd capacititors burned, it was probably soldered on wrong direction. But afterward, adapter worked fine, until recently, when it stoped working, whit no aparent reason.
A question is, it is repirable? It probably died cause that smd, so i could replacing all smds nearby bring it back to life?
It seems that one of the ICs are down.....This had happen to me and to a friend of mine with no reason at all - even default - ......I think the exact same thing had happen to other guys too......:(Quote:

I have looked and there is no aparent destruction noticed on adapter
http://img483.imageshack.us/img483/7...ront9rz0sq.jpg
that smd burned, so i looked and "the thing" right above lookes a bit bad (PC7) but i don't know what it is, to replace it. And i think maybe smd right below could be damaged to.
Those SMDs are not burning down that easy......Could you measure the Mos-fet to see if it's down?......It must NOT show you on a multimeter sort circuit......Quote:

OneProdigy
Are you having the best OC after modification?
Quick question without having read through the entire thread (sorry its really long).
Is it necessary to do the Vcore mod on a P4GD1 in order for the mods on the CT-479 to work?
[Ed: okay I just finished the whole thread]
2nd question: did Hipro5 ever confirm whether the 400mhz jumper setting is effectively the same as the VCCA mod @ 1.82V? Or is there some fundamental difference that makes the mod necessary?
Thanks,
-Erik
I know that these CT-479 mods are supposed to make the voltage more stable under load. I have a P4P800 that has the "vcore droop" problem. Do I still need to do the "vcore droop mod" on the motherboard if I do the CT-479 modifications?
Yes you still need to do it.....Quote:

I did the full CT-479 adapter mod using the kit from Under The Ice...
http://www.under-the-ice.com/index.php?cPath=35
I also did the P4P800 droop mod discussed here...
http://www.abxzone.com/forums/showth...p800+droop+mod
here (in german)...
http://www.forumdeluxx.de/forum/show...ghlight=vdroop
and here...
http://www.broadbandreports.com/foru...cusa~mode=flat
I must admit, I'm a little unsure about the correct solder points for the droop mod. I've seen several pictures that show different spots so It's possible that I've done it wrong. I followed the instructions on the first link above and soldered to the blue and green circles.
However after an hour or so of really difficult soldering, sadly, it doesn't seem to make any difference in my overclocking results. The CPU seems to run a bit hotter (~65C) while running prime95 torture test but the voltages don't seem to fluctuate as much so I guess that's good.
In my BIOS, I set the voltage to the max 1.6V. Speedfan reports my vcore between 1.58 and 1.60 under full prime95 load. Strangely, CPU-Z now reports my voltage as 1.308v and it never changes. I don't understand that at all.
Regardless of voltage stability, I can't seem to get much past 2.7GHz. At 2.8GHz, it usually bluescreens while booting windows.
Out of all the soldering bits on the CT-479 mod, I had a *lot* of trouble getting the holes open for the electrolytic capacitor. My solder sucker just didn't want to work on one of the holes. I ended up heating a needle and working it into the hole to open it up.
I also had a hell of a time piggybacking the 3.2K resistor for the VCCA mod because it was incredibly tiny. I'm not positive that I actually got that one soldered correctly on both ends as the piggybacking resistor was actually slightly larger than the one on the bottom.
Any ideas where I should go next? I'd really like to get this thing to a stable 2.8GHz. I think I'd be happy to stop there.
I know this could be the worst answer, but considering you spent money on a good HSF, you spent who knows how much time on this mod, why you don't look for a better CPU? Dothans are dirt cheap now and ppl is still looking for them so you're not going to trash the old one.Quote:

I have added two 51ohm resistors and this 20kohm pot trimmer to the kit.
Hi there, I'm gonna be ordering one of these kits soon... if anyone else in Europe would like to save on postage, tell me and maybe we can sort something out :)
I also have a few issues with my CT-479 (I think). I've taken VCCA up to 2.5v (measured at the 533 jumper) and gained nothing. I also have a strange issue where higher vcore limits my FSB overclock... 1.6v will give me memtest86+ errors in test #7 at 240MHz, but with 1.425v vcore I can memtest right the way up to 260MHz. I'm thinking this may be caused by electrical noise? Also at 260MHz my board refuses to POST if I use a memory divider... weird stuff. Lower vcore also solved the freezing problem in test #5 at 245MHz up to 260MHz.
Anyway, if anyone wants one of these kits in Europe, let me know!
Just got my kit in the mail today, thanks Run :)
Ill do the mods this weekend, and some testing.
Ill be back with results of before and after.
Anyone have tested T7300,T7500 or T7700 overclock at Aopen i975Xa?
Any new info regarding CT-479 Vmods?
Are the mods posted here the COMPLETE set of known CT-479 Vmods?
Ive heard mixed results regarding CT-479 Vmods. Most people I speak to say they did NOT gain any additional overclock headroom on their 479 CPUs. What is the consensus after years of testing?
TY!
