I oc a Tbird 700

[RobertRoig]

I was in bed already, i had my CPU in my hand and a screw driver in the other. i removed the plastic cover.
The core speed must be in the other side... how am i supposed to see it ?!? How do i remove that clip holing the metallic side ? Well i leave it there on the table by the bed...
and then i remembered of FSB and voltages...
the AK72 looks like only goes till 2.05v but NOT!!!! because if you go below 1v there it goes 3v range of voltages... bloody thing.... anyways.. i put my FSB to 110 and voltage to 2.3 and it works... i have to try with 2.2 still but temp is at 32C and with 2.1 it hangs.
I tried FSB 115 with higher voltages, it makes some more noise... the pc starts... and temp styarts to rise... i changed the settings in the CMOS, and the damn thing just wouldn't start. i had to go back to FSB100 (holding Home key on power up) and so i am here with my old 700 turned into an amazing 770 !!! !!! !!! !!! ... I just want some more out of it. but already 3am...:eek: Zzzzzzzzz:o

hullo and welcome to the board :xwavey:

lolboy has a good guide on his website for removing the covers of an athlon, take a look around the slot a section and your bound to see a post or two by him so just follow the link in his signiture.

he also has details on how to solder the resistors on the board to change the multiplier of the chip using the multiplier adjustment i'd expect to see your chip hit at least 900mhz.

if you don't fancy soldering then i would try to find a freespeed pro, take a look in the buy sell and trade section of the forum and there might be one for sale there.

a few things about your overclock... 2.2v seems awfuly high for a 70mhz overclock and 35c seems awfully low for a chip running at 2.2v... i would take a serious look at your heatsink and position of the probe, if you don't have a probe then i personally would go and get one the on board sensors are normally rubbish.

Welcome to the board :xwavey:

Check my link in the signature at the bottom. Most of the T'bird stuff is the same as the classic Athy's

agreed 2.2 is WAY too high for that voltage..

my sys is 750 w/ 850core @1020 and I have it at 2 volts...

I can get it all the way upto 10x100

I'm guessing your prob is the type that sits under the hsf on the mobo...
innaccurate is the least u could say :(

using needle nosing pliers is prob the easiest..

I find if I push the clips down first and bend them up it helps...

if your lucky u may have a higher core

[RobertRoig]

Well, I got Motherboard monitor 5.0, CPu sensor(max1617-9 Local) 44Cº, the same, but REMOTE says 44ºC as well, one says 22ºC,35ºC and the last one says 33º.
I must say i can touch the silver heatsink there in the middle, and i can hold my finger there for just 3-4 seconds before it feels itchy. so it must be well over 44 ...
I will try to lower voltage.
sensor now at 35 used to be 40 but i put an old's power suply fan to the chasis, Intake air, bent so it's facing the back of my CPU and it got down to 35...
Ok. i got a soldering .. thing... a solderer? (i am not english...) I used to have one.. a pice of **** i should say, bloody big, and messy. Today i fixed an old Sony Diskman, and i am feeling like i am some kind of pro... but i am still not sure of what i am going to do..
i may try to make a partial goldfinger...
as my mother board lets me choose most of the things.
basically all but the clock multiplier, and if i can manage to build a more simple GDF, it'd be great.

The Story Continues...
God damn thing... it almost gave me a heart attack!!!
I removed the CPU once more to feel the adrenaline in my hands...
and when i put it back i seem to have pushed to hard... and the AGP card got loose, and it wouldn't boot.. of course... after much touching and so, i noticed it, and put it back.,
Windows XP was dead.
it took me ages to recover it, and i lost very little!
only some precious hours of needed sleep.

[RobertRoig]

Mother board monitor also monitors voltages...
3.3V is 3.34, but 5V is up to 7.5V and 12V is up to 19.76V !
is it normal?? i guess not. What can i do?

[Pistol]

I'v seen some wierd stuff happen but what your saying cant be a true reading,you should get yourself one of those little ohms meter at Radio shack and check the 12v line,the would be yellow + ground,set the ohm meter to DCv,you can check that any any of the plugs like the one that goes to the HD or CD Rom

[RobertRoig]

The voltages are what MBM say... i just used the tester (volt meter) as you said.. and thwy're 12 and 5 so, just as they should be. Therefore i must think MBM is a piece of ****, or most likely my motherboard is ****.

[Pistol]

I would think that MBM is not getting an accurate reading

[RobertRoig]

well i thought that if temp readings were inaccurate, it was dangerous to keep my Tb running at such high voltages. for some lousy barely-noticeable 70MHz.
I tried all lower voltages to boot 7x110 but it wouldn't. I tried to boot 7x115 (805) MHz I even tried 3v core voltage... i got a bit further than with the 2.5v it reached the veryfying DMI pool data.
I totally disabled cache as i cannot change the divider... so it doesn't affect here. (I've readed it is kind of a bottle-neck, so the cache is not the problem.)

Finally i put back to 1.6v (default is 1.7) with 7x100.2 and got these readings from MBM5 : the core is at 9ºC !! (35 degrees lower tahn before...) it must be wrong, but that means it still working
But actually i just touched the thing and it IS below 20ºC (I'd say arround 15ºC i am going to remove the fan -now-
well not remove... unplug.

be right back...

[RobertRoig]

The temp of the cpu started to raise... (MBM still showed 9ºC) but it was raising, it was only warm, 20ºC then as the fan had been stopped for like 2 minutes. BUT it started to raise. and i just couldn't put the heatsink back to its place.I had removed the heatsink so to feel the very center and temperature of the core.. and it was already arround 40ºC (lack of light and tact (I am on sick leave)) and it was still cooling as the chasis fan was still on I got frightened and had to shut down windows fast. :):p

[Pistol]

your lucky you didnt smoke that thing,it also may have been running hotter than you think and is the temp probe near the core, did you check out Lolboy,s site as to wear the temp probe goes http://uk.geocities.com/lolboy_ninja/

[RobertRoig]

There ain't no probe...
CMOS has some cpu temperature measurements, and usually says 23º or so.
with idle thread process it goes down a bit... i suppose.
I touched the metal thing that is touching the core right behind where the core is, it felt not even warm. until it started to slowly raise...

That's why i made an arrangement to be able to switch between full power fan and half power fan (serial or parallel) Now the fans are barely noticeable

The intake fan is off, but still mounted. see picture :p

[RobertRoig]

picture seemed to be too big (it was 30k but it was low quality large image and maybe didn't fit the window here...)
here it goes again.

[Lolboy]

From the sounds of things you are taking your Athy's temperatures from the motherboard which are highly inaccurate! Put the Athy's core voltage back to standard and get yourself a proper wire thermal probe and install as close as you can to the core (by following instructions on my website you can actually place it next to the core) and get a proper temperature reading. If you don't, you'll run the risk of over heating it and doing serious damage!
Your cooler in the picture doesn't look like its up to the job with two fans running let alone one. The heatsink isn't large enough to dissipate the heat created by running high core voltages. Get yourself a VOS32 cooler (bit of a monster) it's heatsink is about twice the size.
Put it to standard voltages and FSB's back down and sort your temperature monitoring and cooling before doing anything else. :D

Lolboy.

[RobertRoig]

i already did that...
I went back to 100 FSB and got voltage below normal 1.6 instead of 1.7 and temp is so low i can afford to slow down the fans...
Tomorrow i will go to the city and look for some stuff like termal silicon or something, as i removed the clips to see the core and realize it was not a 900 :) just only what i paid for, a 700 thunderbird, and i may take a look at the prices...
for not far from now i will probably be buying a new machine...
i still don't know how much a probe costs, and how it is installed, does it come with a pci slot card? or where fdo you plug it?

The fact that a 1GHz and a 2GHz run flawless the same programs takes the thrill of overclocking to just the fact to know you've done it.
The difference is only noticeable when you make heavy cpu usage... (well 2GHz usually go with much faster RAM better HD better AGP, etc.. but let's suppose they are all the same but the CPU... it makes very little difference. nothing compared to setting a 486 33 to 40MHz or a k6 200 to 240MHz where the speed change was notable.

I may get a good board, and a second hand duron or even a new one, they're cheap. and some day when the offer is right get a cheap XP or something...

[Lolboy]

If you've split your Athy down to the core now is the best time to fit a probe. Check <i><a href="http://uk.geocities.com/lolboy_ninja/resources/temp_pr_loc.jpg"> this link</a></i> to see where to fit it. You should have a header off your mobo for plugging it in (not all mobos have them though)
