210 ran SuperPi and PiFast and is running Prime95 now. ;) Before this mod I would never have been able to boot into Windows fully and I damn sure would NOT have been able to run even 20 seconds of SuperPi let alone complete it and PiFast and get to test 3 of Prime95.
Damn fine job Learn!!!
[edit]215MHz FSB ran SuperPi and PiFast and is running Prime95 now... :D Remember when I was stuck at 205MHz? ;)[/edit]
Looking to me like I will have 2 mods to do now...........:D
Can someone snap a picture of the finished mod?
I know my way around with a soldering iron quite well, I'm just better when I have a diagram of sorts to go by. :)
Thats fuggin awesome Jeff!!!
wtg Learn!!!
The Vdd(chipset) mod described in this thread will VOID YOUR WARRANTEE!!! Only attempt the mod if you understand this and are willing to risk damaging your board since any voltage above stock can damage the voltage regulator and/or northbridge(and video card in one case). PROCEED AT YOUR OWN RISK!!!
217MHz FSB running Prime95 for 15 minutes now... :D
Here's a fuzzy picture of the mod done with grabbers(only temporary until I get a 1k VR)...
Jeff what grabbers are those and where did you get them?
also are they small enough to fit on the leads of this surface mount IC it looks very tight
Awesome. Thats exactly what I wanted to hear. :D

This chip is about the limit as far as fitting goes. The newer surface mount chips have the pins soooo tightly packed that it's almost impossible to get this type of grabber on them.
can you tell me more about them it says there black but you got a red and black and do the ends of them have a metal click to solder on a wire?Quote:

You notice anything in there getting any hotter Jeff?
SB/NB mem... ?
AMDGamer, yeah... it says black but I got a baggie with both red and black in it. And yep, they have tiny metal claws for gripping and a tab on the other side for soldering a wire onto.
muzz, the northbridge has gotten a bit warmer while the southbridge hasn't really changed. Although... I added another 80mm fan blowing across the board so that may have helped a little too.
BTW... 220MHz FSB seems to be running fine atm!!!
Thats very cool munnnnnnn , I am psyched for ya considering what you have gone through to get this board to do what it should.
U deserve it......... enjoy bro!! :toast: :D :toast: :banana: :banana:
Thanks muzz!!! :banana:
You know... I'd be interested to see what your Vdd is using a DMM. If it's like 1.7v or higher then I think we can say for sure that is what has helped you. If it's only 1.6v then I think you just got lucky and are running a 'magical' setup. ;)
Hopefully it is low like the USDM says... that way I may have something to look forward too.... I can't help being greedy. I want performance!!!!:D
Where do I measure again?
:D :D :D
KICK ASS...
Im very pleased :D :D
can you get a thermomiter on your NB and se if you get any big temperature rises.
I would be slightly worried about burning the NB out when your pushing it hard, its worth keeping an eye on it anyway.
Are you measuring off of pin 1 Jeff? or are you going by USDM?
excuse me for my ignorance, but this mod changes the nF northbridge voltage, right? Just gotta make sure 8-)
I wonder if those insanely hot running 8RDA's have higher voltage on the nb? Maybe this is the issue and they are running with too much voltage?
Jeff, are you running dual channel @ 220.. and no screen flashes etc.?? That is great!Quote:

You guys are awesome for figuring this puppy out...! Can't wait to get the heck outta work and do this mod!!!.. I'll slap my 10 turn 50k pot on there and see what she does!! :D

Yep, dual channel DDR. ;) And I just installed a 680 Ohm resistor instead of the 750 Ohm and now my Vdd is up to 1.82v. At 1.79v my 220MHz failed around test 15 of Prime95. Now at 1.82 I'm at 221MHz and still working up. I'm pretty sure my RAM is going to start failing soon so I don't see the point in raising Vdd up much more than ~1.85v.Quote:

You really only need a 1k... maybe 1.5k variable resistor for this mod. The high resistance will only add a tiny amount of voltage. Wait... at 10 turns, that might be a decent resistor. :confused: I dunno, just be careful when you get on the low end of the scale. Learn already put over 2v to his northbridge by accident but he got lucky and nothing bad happened.Quote:

Let us know how it works out for you.
can some one take a pick of all the stuff i will need for the volt mod?
and a link to where i can get everything if possible
You only need a 1k cermet potentiomiter and some wire, plus a soldering iron.
(and steady hands + soldering skills)
guys how much voltage would I get if I stuck a 10k R on there?
and where do I measure the resulting voltage from?
so what is the variable resistor for and i am going to use smd grabbers (hands are not steady)Quote:

YES!!! works like a dream! just put my 50k-10turn pot on pin 1 to ground (I used case ground ~ me lazy and don't like too many smd grabbers)
I turned the resistance down untill I got ~1.66vdimm, ran some 3d mark at 205 with NO flashes, artifacts, etc!!!!! It definitely works because this was not possible before. Now it's just a question of playing with the voltage and finding out where the memory starts to become an issue..
NOTE: If you are going to use a large resistance pot, such as 50k, be CAREFUL when turning the resistance down.. The area where it starts to increase the voltage isn't untill you get down around 2k ohms or so.. Then the voltage starts to move up fast! Turn SLOW..
I think I'm gonna love this board!! :D
:banana:
Yeah!!
Oh how I love to hear that the vdd mod works :)
Hopefully I will be able to join the 220 fsb club.
Now just one more thing and this board is just AWSOME...more vdimm.
