hot gluing the the resistor to the mobo doesnt hold for sh*t. im going to have to solder it to the smd(i assum that is what it is). i was planning on doing the ddr mod tuesday as well as the correct vdd mod.

and trust me, i tried tightening it properly, thats how i already stripped one mounting screw, therefore only leaving me with three mounting holes. that in turn is what is causing the no contact. i used plenty of as3 and when i removed the pelt it looked like it barely made contact, not the usual imprint of the core in the as3. i need another freakin screw... o well, i put my hhc001 back on and it runs fine right now at 11x200.

once i get the mods done and possible the slk900u i may start cranking it up again.

I had mine soldered by a professional :p It's too crappy to be done if it's not your job and you instantly kill your MB. I've done the others myself without any problems (Vddr & Vcore) After that I've hot glued the wires to the nearest caps so as not to put *any* bending pressure on the soldering. I think it's safer for long term.

Have a look at this article and check whether you can use the same method for mounting your waterblock (I don't know whether it's better, but worth a try !):

Hope it helps ! :D

I did all mods and results were quite good. So far 242MHz sync DC in Windows and running few test is no problem. VDD 2,05V VCore 2,05V Vmem 3,2V and timings 4-2-2-2 (Kingston HyperX PC3000). All this is possible by using GF MX. When I switch back to Gf3 Ti500 or Radeon 9500/9700 serious problems occur and system is barely able to boot at 230MHz.

I also noticed that high Vcore used kill FSB overclockabilty and so I did 5V mod. Now it works flawlessly on high FSB and I even managed to overclock CPU little higher. 24/7 2555MHz 2,05V and quite happy.

Thanks Guys for this MOD, It works like a champ! :toast:

Haven't installed my 462-uht yet so I won't be posting any screenies but I love this board now :D

HOLY SHMOLY DURONBIRD!!!

:slobber: :slobber: :slobber: :slobber: :slobber:

Is that prime95 doable/3dmark? or is it just boot do the mem test and crash? :)

Eitherway its absolutely incredible!! EXCELLENT WORK! :toast:

Duronbird/Morkai: Welcome to the forums both of you and VERY NICE SCORES!!!!!!!!

I am deff. going to have to try raising my chipset voltage. I'm only @ 1.9v and doing 240mhz. I think if I did 2.05v like you guys I *might* be able to do 250mhz sisoft.

You guys really need to post those sisoft scores here: http://www.xtremesystems.org/forums/...4&pagenumber=2 :)

Asus A7N8X deluxe rev.1.04. FSB tests.

Volts:
Vmem 3.25V
Vcore 2.22V
Vdd 2.1V
Vio 3.8V

CPU was -20 degrees of celsius. Chipset was cooled with peltier and water.

Highest stable FSB was 250MHz (11 x 250,57MHz), but Asus, we need some more ;-)

For those of you who are afraid of soldering on the resistor (including me) I can give u a little hint, I will VDD-mod my board using glue which is conductive. Just use a nail or something small to apply the glue, I suppose its relatively easy to remove it if u screw up ;) Happy modding!

Soldering is not that bad, I use a multi stranded wire in which I remove all strands but one, I then coat the single strand with a bit of solder (Remember a tiny bit), I then pre-route the wire to the location where it is to be soldered. I use the glue-gun to adhere the wire to the Mobo to hold it in place, so that after it is soldered no stress will be placed on the solder joint. I did not solder the resistor directly to the board. I then hold the wire against the solder point and then with a very fine tip soldering iron I touch the wire and it joins very nicely with no excess heat. That worked for me and I suggest practicing this on an old board you have hanging around, this will help you gain confidence, I did this and it worked for me.

See the pic to see what I did

Did you solder to the IC or the surfacemounted resistor? Everything else is crystal clear, I might give soldering a chance since i have a soldering station with a 0,5mm tip.

It looks that way from the pic, but no I soldered directly to the SMD resistor. The reason The wire is dropping from the back is that I did not want any possibility of any short.

You will also notice that I used the ground closest to the component I am modding, you can easily check this by using an Ohm meter and checking continuity between the Ground on the Fan header and any spot on the motherboard to locate a safe ground, but this is up to you, I just did not want wires all over my board. Good luck and May the Nforce be with you ;)

Savon Mafia, how are you getting 2.22 Vcore? If I raise mine any higher than 2.06 it won't POST no matter what FSB/Multiplier setting I have it at.

My VDD mod up close...

I used like 22 gauge solid wire, not stranded. And directly soldered w/ a 30w pencil tip soldering iron!!!! And it survived! :P

Either im just a complete bonehead when it comes to soldering or something is wrong with my equipment. I've been practicing soldering to an old intel graphics card (only thing intel is good for ;) ) and the friggin solder is §§§§§ing and wont connect to the SMD. Any clue? What temps should the iron be at? I can set it between like 200 and 450 degrees celsius. Maybe my solder is §§§§ or something? :(

Make sure you are using a low temperature solder that is also very fine.

By fine u mean small diameter? I have 0,8mm now. Its a 40/60 combination and the meltpoint is 183-188 degrees celsius and it has fluss (or what its called :) ).

Well I just re-soldered my VDD mod... I now am using a 1 MegaOhm + 470K... that should give me PLENTY of headroom :P I also chose to use a 22 Gauge stranded wire, and cut of 6 of the 8 strands. So it's nice and thin, soldered it to the side of the SMD, hot glue gunned it down and gonna go down and fire the beast up pretty soon. My cable was down for like 2 hours, so I'm catching up on what I've missed :P

The solder size is good, perhaps the iron temperature is not hot enough. My iron was fairly hot when I perfomed the soldering and unfortunatley my iron lacks a temperature control :( One additonal note, after the wire has been coated with solder, make sure you let it harden for 20-30 seconds before attempting to solder it to the SMD. At least you are practicing on a crap board first, so worse case scenario there is no harm done.. :) Good luck!
