nice that is real easy! i will do that tonight (running prime on my system now and downt wanna have to turn off pc and do prime all over again)
Did the VDD mod today, thanks for the info guys :toast:
I used a 680 ohm resistor that gave me around 1,8-1,82 Vdd.
Before the mod I could not run above 185fsb stable, now I can go up to 200. Anything above 200 is unstable, at 205 the system wont even post. Anyone know why I cant go any higher?
Im using two TwinMos 3200 sticks.
Thanks
Espen
Damn .. i cannot put the grabbers, the is no space between the leg of the chip and the board. Need to do some soldiering :(
i did the mod here with some high res pics if anyone wants to check it out

Are you running a 2400+ or higher cpu? If so try taking the 133/166 jumper off. I also had to cut L12 bridge to get it stable and make the chip think it is a 133 part. Then I could run it all the way to 220fsb.Quote:

Thanks for the welcome N8
i did the vdd mod successfully, im running at 1.84 right now, but i still cant get above 202. it seems that no matter what, the cpu will not post above 202fsb. if i set the cpu to 180 and set the ram (async) to 125%, the ram will run easily at 225. if i try the opposite, and run the cpu above 202 and the ram at 80%, it still wont post, pointing me towards the cpu as being the culprit. ive taken off the jumper and didnt help. so im thinking about cutting the L12 bridge. anyone think this could help?Quote:

edit: typos
I replied to one of your other threads, but first saying that there is no guaranty, the L12 cut helped me on my 2800+ get to 220. I also did the vdd mod which helped with stability, but just taking the jumore off didn't really hlep my cpu whereas even before the vdd mod, I noticed a decent fsb bump after cutting the L12.Quote:

but what mult are you using? im hoping to get an 11 or 11.5or even 12 mult out of 210+ fsb. at 11 *210 thats only 2310 which is only a 152 mhz overclock for my 2700+Quote:

WOW !!!
HOLD THE PHONE.
I could not get past 197Mhz - even at 6.5 multiplier
Now we are in business.
Stuck it on 220 fsb and it is fine.
I´d never though it could be pushed this far at all.
AMD only :-)
1700+ Palomino @1700 hz @1.95V
Eopx 8rda+
Corsair XMS 3000 CL2 @ 2.5-3-3-7 @2.77volts
Ati radeon 8500 250/265core @1.7V
Volcano 7+
I used a pot 1 Ohm 0.75w
Used a multimeter to test the pot beforehand and dail it in to 800Ohms resistance and stuck it on.
This pushed the VDD mod from 1.55 to 1.75volts
I thank everyone.
This has been the hardest and most rewarding overclocking since my old dual cel366 to 550 mhz on a Abit BP6.
Long life the EPOX 8rda+
Thanks Guys
!!! Happy New Year !!!

Which resistor should I use for a maximum Vdd 1.9V?

Im running an 2400+ and removing the 133/166 jumper didnt work. I have just tried running the fsb at 225 and memory at 80% and it worked fine. Ive also tried running the fsb at 180 and memory at 225 and it worked fine aslo...
It seems my board doesnt like running in sync mode...
Edit: Max stable fsb in sync mode is 203fsb @ 204 the system wont even boot...
550/600 ohms. You need a good cooling on the northbridge for this ;)Quote:

One guy from the Epox Techteam @aoaforums says this "Given that this is an 8x AGP MCH, voltage isn't derived from the same channeling method as that of say a KT333 mainboard for the MCH. It is created on a pass through the IR chip that you are all retracing with the 1K ceramic or pot.
The MCH voltage is linked to the AGP voltage across certain paths only. These paths are critical for the graphics card to stay alive, or in modifed instances "dead".
We would recommend against this modification as I have stated - it will cause multiple component failure. The only way to acheive this modification would be much more complex than the modification that has been carried out. It would mean uprating a great deal of circuitry" whoops.....
So it makes you wonder what voltage increase is actually helping... the chipset or some lines for the AGP?
Like I said... my problem before the Vdd mod was my video would crap out and the video driver would corrupt. Which is really inline with what that ET is saying.
hmmmm... :confused:
I am using BIOS C31.
Before Vdd mod, >210FSB = screen flash
after Vdd mod (1K Ohm resistor, 1.78V DMM reading), >225FSB = screen flash
But I am OK with this 225FSB :)

Yeah well, screens are not a good proof.....
http://www.xs4all.nl/~bruuuuut/hehe.jpg took me 2 minuts with paints lol
Cpulloverclock, how do you cool your northbridge?
sorry but I never cheatQuote:

my score is not a fake
okay? :)
for my northbridge there is a 60mm fan
:) I don`t say you cheat m8, I say benchies on jpg are not a proof. 3dmark is...... with an url that is hehe (and I gues you know how paint works because you copied my reply in a jpg, and the colours of the pic are exactly the same of MS paint)
Are you referring to him quoting your reply? :)Quote:

11 & 11.5 works great now.Quote:

Answer me goddammit!:slash: :D
Will this work for the a7n8x? Im too lazy to look :)
