Good luck SAE with the freezer peeps
;)
Let us know how u get on.
texuspete2k2,
My first Infinity had a red hot southbridge, the heatsink used to get really hot, this one isnt so bad. I would say that it is slightly over luke warm and yupthat is my nthbrdge heatsink on my southbridge.
I think i may have sorted my lan problems, ill know better tomorrow morning when i wake up, will be leaving the comp on again (third night running) hopefully the LAN will be working fine when i wake up.
If it is then I have to atribute the problems I have been having to unsuccessful bios flashes. Today i decided to do the bios flash the DFI way...which is the following procedure (info from Amdmd.com):
I flashed to the 121 bios today and followed this procedure, it seems to have worked, will know l8r.Quote:
Question: What is the best way to flash my BIOS?
Answer: After flashing your BIOS, you should power down the computer when after the flash procedure exits and restarts your computer.
For the best guarantee that everything works properly:
1/ Unplug the power cord to the computer to completely power down
2/ clear CMOS jumper for 30 seconds
3/ Power computer back up, and immediately go into the BIOS
4/ Choose "Load Failsafe Defaults" or "Load Optimized"
5/ Save and exit
Immediately after reboot, go back into the BIOS and configure to your liking
Clearing CMOS after a flash helps clear any old settings in the BIOS that might conflict with the new BIOS codes.

This pic man...
Looks like your southbridge heatsink is on your northrbidge, not the other way around. Unless I've lost my mind. Looks like the 100fsb jumper etc. Just curious is all.Quote:
lol,
Yup you are spot on, I think i misunderstood your question. That is indeed the southbridge heatsink on the nthbrd!
The reason the picture was like that is because I was still testing the mod and had my mthbrd on my desk. The nthbrd heatsink was firmly attached to the southbridge and i didnt want to pull it off. So as a precautionary method i just dumped the southbrd heatsink onto the nthbrd to do my testing.
The reason why I havnt got a nthbrd heatsink is because I have a waterblock for it. Setting up the watercooling stuff out the case is a bit of a mission, hence the temp measure you see in the picture.
Hope that explains what u can see

Have we managed to work out the optimum value for these resistors yet? :)Quote:

Hopefully by the time i get back there will be some new information on the optimum value for the resistance needed.
Am I right in thinking 3.3k would be about right for this mod? :)
Cheers
I'm curious about NB temps to.Quote:

Some peeps say that it runs higher FSB's @ higher temps, but this seems kinda illogical 2 me. :rolleyes:
Anyone have some info on this?
anyone?Quote:

I want to order my parts tomorrow so I can mod it this weekend
Do not know if the mod worked well cause I am fighting massive bios corruption problems atm :(
With the prom I did not have it so excessively... :mad: Do not know if it is that what makes it worse...
I have done the mod with 4,7k ones.
Vdrop at fixed 24k atm :)
What rev are your guys' NB's?
Mine is an A1... 0348 production date.
My LP B one is 0335 iirc, and my infinity one (new - but never booted up right now - got today from rma :rolleyes: ) has 0348...
:cool: I think it does not matter anymore if it's 35 or 45... they do perform equally ;)
bigZ,
Ive got 3.9kohm resistors attached to mine, all good so far.
STEvil,
Mine is a 0348 one. Seems to crave more vdd than my 0335 one did. I had to do the vdd mod today to really stabalise my 235mhz bus speed with 3 sticks of ram occupying my dimm slots.
SAE,
Glad to see you got your mobo back, care to elaborate on your bios problems
mong
4th BIOS hotflash so far... impressive bios safe procedure it seems... :rolleyes: Seems to mess up all the data mainly when changing vcore...Quote:

LP B is my favourite though... the infinity never booted up although I only have attached psu, cpu and ram, plus gfx card...
Maybe a hotflash is necessary even before using :eek: LOL
my infinity has been a :banana: :banana: :banana: :banana: :banana: ;)
A1/A2/A3/C1 though, guys?

Hey vlad, what 's up? Do you have trouble with people on this forum :confused: ?
n
i dont have trouble with most people here, and i didnt have trouble with anyone here some days ago, hell even fugger could be ussefull for me now that i am doing things with p4 if the ambient was more calmed, but the current situation doesnt give me much peace of mind seeing the ease to delete posts and members, move threads to where they cant be reached, edit post, spying pms, i really fear for the whole forum to go down definitely/whole database to get deleted, of course i dont really know for sure how true are fugger or the other parties arguments, but here everything is becoming spam and flames, while in the other place at least doesnt delete/ban people as easily, it isnt full of flames, there are real moderators, and everything makes me at least feel sure that if things get real ugly i will have a chance to pack the important stuff and go to other place, it is also a determinant factor to see some people i really admire resigning as mods or as members and getting their resignation posts deleted and his threads covered with flames.Quote:

and another time i hope my statements here dont get me a ban as this might get to be a good forum in the future, but sorry now it isnt.
EDIT: yeah now i have
Maybe I seem a bit dumb now ;) but I did not really notice these things going on... *cough* Okay. I think I know you would be there if questions occure :D
I hope these circumstances do not last for long, we are losing too much superb members these days, it seems :(
cheers, I'll go with that then, thanks :cool:Quote:

hy people
i make some tests and i have good news,vdroop mod is not necessary.
let see de results:
these values are obtain with a multimeter.(windbond hardware monitor is not fiable,it shows false variacion on the voltages)
overcurrent mod with original resistors(2.2k)
cpu at 250x10 vcore 1,9v vcore idle(1.906v) full(1.897v)
overcurrent mod with other resistors(3.3k)
cpu at 250x10 vcore 1,9v vcore idle(1.913) full(1.906v)
cpu at 240x11 vcore 1.9(vcore moded) vcore idle(2.097v) full(2.090v)
when i put more than 2.1v on vcore the computer freezes on windows xp logo,can someone why this hapen?
when increasing the resistences from overcurrent i dont see increasing v droop,good,its fine,no vdroop mod need :banana:
also i solve my cold boot problem,i change the cpu(barton 2500+ mobile 1.45v default vcore) default voltage to 1.8v and no more problems on restart and power on:banana: :banana:
Where are you measuring the vcore at?
I measured at the choke, but i'm unsure if that is a reliable read point.
YEAH!! Seems like I got one of this magical boards where none of the mods is needed except Vcore mod. :D
I went up to ~2.15v .. no instability. I need prommy please sell meh !!!!! :banana:
Edit:
Hm I discovered that my Vcore still fluctates by 0.05v, then I took my Multimeter and measured at the choke. Stable 2.059v idle and stable 2.048v load. MBM shows values from 2v to 2.05v so i think this is only a BIOS problem. :cool:
-te como yo.
Eh? :confused:Quote:

Any results yet? Mine stuck at 2.05V (bios reading)
Also, I'm confused about measuring the vcore with a multimeter. I always want to do it but never know how. When you say measure the Vcore on the choke, are you talking about the biggest choke near the socket around the mosfets? Do I just stick the multimeter on the coil?
Also, I've read if I slip, it's dead? Is slip = shorting it with order components?
Didn't do modz as things are getting to work :D.
But have killed 2 boards w/ slippage.
Be VERY CAREFUL and if possible keep finger near PSU power switch. If you get it fast enough after contact, you may keep your board. Kill power if you see/hear ANYTHING, don't wait for smoking stuff to happen.
I poke at the solder point on the motheboard, must less prone to slippage.
Hmm. :confused:
Vlad, may I ask why you removed all the important posting of yours??? :(
Okay. I am at least gunna repost the missing pics...
And the other one...
edit.
I must add the credits go to Vlad for this mod and picture. Bad circumstances... he's not here anymore. If you got questions to ask you'll find him over at XR.
If we completely removed the overcurrent resistors... would that be a bad thing..? ;)
I definately think so. Resistance would be infinite and thus surely some part will dies/burn. Would be very ugly. I think those are also there in a protective sense...Quote:

If they are only current limiting, though, removing them should only increase the maximum amount of current to infinite..
Wish I had spare boards to play with... :/

This should work right? (of course after the SMD ones are removed) Just want to make sure before getting my soldering iron out.
The reason behind this is
1. I want to have control over the resistance so I can enable/disable when I like
2. I have heatsink on my mosfet with artic adhesive
3. I can't be bothered to calibrate different VRs
Don't do it this way, as every smd resistor depends on other electrical factors, and trimming them over one pot would be bad the the onboard circuitry. Vlad lined out before (shame you cannot read it anymore) that it would be dangerous...Quote:

Do it with smds at 3.7k or 4.4k and you'll be fine. No adjustments anymore (I have 4.7k ones). And I also have adhesive sinked the mosfet transistors...
Good looking mods... i cant seem to find anywhere it says what amount of resestence to use.... ?
What are people useing for the Vcore? Do you have to make the Vsence the same as the Vcore? im a little confused on hoe you go about tunning that in. (2 pots for one goal)
What do i replace those SMDs with? 4.7k resistor?
What about the the Overcurrent mod? it says to set it and forget it, but what to?
see that 8-legged chip next to #2? That thing gets really hot!!! :eek:Quote:

i suppose the one next to the northbridge heatsink may also get just as hot.. but after burning my finger (this is with over 360cfm of airflow) on the first one i didnt bother trying the other.
Yeah. I already supposed to cool these driver ICs... the middle on of the 3 should indeed be the hottest...Quote:

heres a better pic of the vdroop mod.

Hehe, Evil, your pics are everywhere ;)
hehe, i figure if i can help people out with better pics i will! :)
besides i enjoy taking them, its a kinda hobby for me.
if anyone has any requests for pics of parts i have just let me know ill supply them. give me a day or two and ill have similar pics to the one above. feel free to ask :)
infinty pics ask ASAP, i have an extra board i might be sending back soon.
hello,
well, i have read the 6 page of the topic , but i don't understand how to do the vcore mod, because my english is so bad and your discussion about vcore mod is so blur for me :D
Can you please make a step-by-step how-to for me? I need all details of your VCore modding adventure :D
Please PM me,
with my infinity i have do this :

so i need more vcore to go up !!!!!
thanks ;)
evil spork - what is the original resistance of the resistors for the vdrop / vdroop mod and does anyone know why making the resistance 0 would be a bad thing?
2.4kohm iirc... but dunno exactly. :)Quote:

If you short those OCP resistors you'd allow full current to pass through the circuits and go directly to the CPU. I would consider it a very bad thing if the CPU was grilled by too much current ;)
http://www.xtremesystems.org/forums/...048#post451048
I was looking at evil_spork's pic wrong.. my bad.
All I want is a stable vcore... :D
Pin 4 to choke is what that pic looks like, is that correct? All I have is a 10k VR... wonder if thats too low?
No. That also wrong :DQuote:

It's pin7, and that's the vdrop mod. It will drop your available vcore too, but make it more stable (less fluctuation).
The OCP mod is changing those SMDs to 3.3-4k (more does not really help, dunno if it does not even worsen it)... you would get more current flow to the cpu mosfets thus supplying more to the cpu...
1k VR is not too low for vdrop. I am using a 4.75k fixed res. But you'd have to put the vcore mod to pin7 as well to compensate the decreased vcore (vdrop)... set vcore to 1.825V in bios and turn up your vcore watching the voltage in bios. You should be able to get a more stable voltage output this way too.
Gluck, pal. :thumbsup:
Counting from the left its pin 4.. ;)

That's not the vdrop. Don'T get it wrong... that's OCP!
yeah.. thats what messed me up when i looked at it ;)
