Hi,
I wanna do this VDD mod with SMD grabbers.
But I have got a few questions before doing the mod:
-Do I need only a SMD grabber or need I anything else?
-Has anybody done the mod with SMD grabber?
-How to adjust the SMD grabber?
-How are they called in Germany?
@LEARN - Is that dual channel sync????
God I hope so :D
yes it' s in dual channel synchro :D
timing: 2,2,2,7 aggressive 2.9v
Wow, thats awesome. I can't wait for mine to show up :brick: :cussing:
hi,
@kingxxl
smd grabber = "SMD PINZETTE" search at reichelt.de or conrad.de
u also need a SMD POTENTIOMETER or SMD TRIMMER ohms are adjustable per poti
or use a fixed WIDERSTAND
hellll yeah... rockin' on 225FSB **** stable with 1.9V VDD =)

damn it the vdd mod stil did not do anything for me:(
so i finished the mod and booted up fine my vdd now reads a steady 1.82 so i decied to go right to 220 FSB thinking it would be ok and for the first boot it was i booted into windows fine and everything ran sandra got 3200MB/sec ran 3dmark without any lockups so im like cool it worked but then i went to run Prime95 it gave FATAL ERRORS about 1 second into the toture test so i thought 220FSB was still a bit to high so i restarted went into BIOS and changed my FSb to 215 now guess what, it would not even POST so i had to reset CMOS and go to a FSB of 210 this time it booted into windows ok but once again Prime95 gave me errors about 1-2 seconds into the test so i am back at where i started i even changed the cooling on my NB to a vantec copper iceberg
now here is something interesting it seems that my max synch FSB with my Corsair PC3500 is 200FSB @ 4-2-2-2 anything above that will either randomly not POST/BOOT or will give errors in prime 95 1-2 seconds into the toture test but i did a little expreiment i went into BIOS and cranked my FSB to 225 and changed the memory ratio from automatic withc is SYNHC to 80% and guess what it boots just fine and runs prime 95 now could this mean my Corsair PC3500 sucks or what could be my problem?
try to do the opposite, set the fsb to, say, 180 and do the memory at 125% (225 in this case) to see if your ram is capable of this speed. im guessing this wont work tho, being that the cpu is capable of doing the higher fsb when the ram wont.Quote:

This test will just help u pinpoint the ram as the culprit.
ok i just tried FSB of 179 and ratio of 133% or whatever for 226 on the memory now it booted into windows and everything just fine but once again prime 95 gives errors 1-2 seconds into the toture testQuote:

also if it was bad ramnot FSB wise but damaged witch im testing now with memtest86 then why would it work at all?
Did the vdd mod at around 740 ohms on the arda+ and vdd went from 1.58-1.6 to around 1.84 and Now can run at 220 at least whereas before I maxed out at around 212 for stability. This was in combination with cutting the L12 on a 2800+ previously which hleped get over 200 at max timings to begin with. Only problem is it really needs a sodder. there really is very little to grab on to and I feel like if i sneeze, the micro grabbers will fall off. Also I have a 9700. If it was a 4600, it would be right under the card more or less and even harder to keep on.
Any chance this would work on a A7N8X? And if so could someone help me out here? :)
this is the best pic I`ve got so far

What do you all thing about my noname pc2100 ?
How high do you thing i get with this motherboard ;>?
Im on my Epox 8kha+ rev 2.0 (Kt266a) and max the fsb to 146 ://
Do you think i get any higher with this new board ?

Okay, I know im new here but just a little round-up would be greatly appreciated, I got the test clips (grabbers), I don't have a steady hand, I got the Pot, but personally I'd really rather not do it this way, if someone could tell me what strength resistor I would need to get ~1.79 volts it would be greatly appreciated. :)
To those who have soldered the leads on, were you able to do it with a standard size soldering iron, or did you need a specialty iron? I consider myself quite good with soldering, however, I did notice the area is kind of small.. it looks like it can be done, but I'd like to make sure first. :)
Someone that want 2 answer my question plz ?
I dont know if i should get it or not but;) it looks like a nice board man ;)
R:eek: :eek: :eek: :cool:
Jeff gets that with 750 ohm.Quote:

Welcome to Xtreme :) (hope i didn't miss any1)
Oblic,
There is no way any1 here can accurately tell you how high your PC2100 will clock in the 8RDA. I'd recommend some good PC2700 to PC3500 in the board tho to fully take avantage of the bandwidth ;)
Ya I understand that aswell but ;> the system Iam on right now have the pc2100 and I dont have aford a new memory ://
I just want 2 know what you all think ? Do you think im going over 146 ;> ?
and btw im getting the board anyway ;)
more results later guys
I have some PC2100 that won't even run Cas2 @ 133FSB & I also have some that'll run Cas2.5 @ 166FSB...so you can see, its very hard to say ;)
ya thats true ;>
Thanks allot for the answer and the warm welcome ;)
Keep up the good work guys.

:cool:
can somebody pls tell me if i can do this mod with the two vmod things i have? i have two "vmod kits" i ordered from someone at overclockers.com
What they consist of is a grabber, going to a pot, going to a ground connection.
If i hook up the grabbers to pins 1 and 4, then what pots do i turn and how much? (counterclockwise is less resistence)
Emericana,
Not sure what you're asking but if I understand you correctly it should work fine dependin on the potentiometer size. Set it to max resistance & connect it to Pin 1 & grnd the other side. Then turn down the resistance slowly & watch VDD go up :)
If the pot is 1k or more then you should be fine :D
