thats it im going to try this :)
I can do about 230-233 with 236 posting but not much more and only at very high Vdds... even 230 needs 2.15-2.20 Vdd.
I'm happy with the CPU overclock though, no problems there, although it does overvolt quite heavily, my NF7 V2.0
I have added caps to a P4T533 in the past, and if the caps dont fit the board, you can always solder wires to them and run them to the board like that... may look crappy but it works ;)
I checked with heaps of manufacturer's and the smallest diameter for 4700uF was 12mm even for 6.3V parts.Quote:

i also need to get a soldering iron. do i want some sort of low power 15w one for soldering mb stuff?
like this one http://www.maplin.co.uk/products/mod...52&modulecode=
I think for caps im gonna get 16mm diamater ones such as part no. 315-0287 from www1.rswww.com. rated as 6.3v, 12.5mm, 4700uF, 0.025 impedance, 2310 ripple and 5000 hour lifetime at 105c.
could get even better ones but the next ones up are 16mm.
That will be fine, I have the 18W version. Make sure you get a 0.5mm or 1mm bit as well, part nos FT03D and FR05F are suitable for that iron.Quote:

I like JC's idea of attaching the caps via wires, sounds a lot easier than replacing the current ones.
This is going to be incredible if it works for other ppl. I'm not brave enough to try without more confirmation so hurry up and post your results all. :D

Not that good lookin but it works ;). Three 4700uF 10V caps and four 2200uF 6,3V in pairs. Guess ill clean it up sometime but for now this will do :).
I think it good that I keep most of my blown up mb's around ! hehe
I'm going to try this next week, I'm just going to cut out the mb mounting panel underneath the cpu and around the caps so I can still mount it in the case.
I don't remember if it was Charlie or not that had added caps to an Asus P4G8X in the same way.
I'm gonna try this on my rev1.2 :)
Let us know :)
can i use only 10v caps? because 10000uF 10v is easy to find
I scrounged around the drawers and found an assortment of SAMXON 2200 16v and 25v it doesn't really matter.The 16volters are fatter than the 25 volt ones too.
The wire method added to the caps sounds good also. Or else I've got to find some skinnier ones. I don't have any stilts to mount the motherboard on the case tray. :D
Or I'll try and find some higher rated than what is on the board now. Maybe even replace the ones on there now.
I wonder what most of us will be doing shortly?:rolleyes:
Yes you should be able to.......Quote:

That's simply amazing! My nf7-s died some time ago but i got two EPoS mobo's now... what the heck, i'll try it on Epox.
caps can be soldered on any way around right?
what id like to know is WHY this would help anything going from 2200 to 6900, since i know very little about this stuff but i like to know the theory behind what i am doing :D
yes DEFINATELY get the polarities right. they are marked clearly on each cap (well they mark either the + or - side, typically the -)Quote:

If you mount them the wrong way they can explode, and could damage your mainboard
basically its all about more stable, cleaner currents. For example, when your FSB is too high and it crashes, it means a huge amount of errors were created due to the signals not being clear enough. reducing the amount of "interference" will get you higher clocks ... thats just a basic explanation im no expert and could be wrong here and there
Any results yet chaps? :D
I've seen mods like this done before, a guy did it to his MSI 745 Ultra on OCWorkbnch several months ago, if not a year ago.
but definitely a good mod!
I'll have to give it a go sometime :)
once ive decided what caps to get what i might try is a temporary mod and maybe try to just tape the new caps on the back just to see the effect before i solder anything. it would also be interesting to see if its any 1 particular cap that solves the fsb problems or whether is all of them so i plan on testing them 1 at a time (i assume this is safe to do or must i do them all at once?).
omfg..
thats insane. do you just leave your board out, or where do u keep it? those caps look extemely huge for some reason.. am i seeing them bigger then they really are?
does radio shack carry those? where to get em.
Essentially what the capacitors do as stated previously is they filter voltage running trhough them, but more importantly in this case they also Stabilize the voltage, The higher the Capacitance the longer they are able to hold the voltage stable, a low capacitance might be able to hold the voltage for a few milliseconds, a high value Cap might be able to hold voltage stability for .5 seconds, possibly even more depending upon the current demand. So when voltage demand exceeds supply the capacitor takes up some of the slack. Then when demand falls off the capacitor is recharged.
ok so whats this 'ripple' rating?

Basically whats a ripple? A small change in voltage in this case.
Well this is my first post at this forum. Basically it's all thanks to Hognert.
I've done the mod and she is running beautiful at FSB 250MHz.
3D running ok at 240.
Well you can see it here:

I used wires on my five 6,3V 3300uF rubicon caps that I took from an ruined KR7A:

And attached to the MB:

Once again: Thanks a lot Hognert

Jason, Welcome to Xtreme:D
Nice work there, you'll fit in just fine ;):cool:

most importantly though, how much did it manage (3D) before the mod...? We're all interested in the difference/gain in all this :)
Also, what cooling, vdd... etc :)
cheers
Well, here it is then JCviggen:
The rig is watercooled both on cpu and nb.
3D no good at anything above 220 before the mod.
vdd: 1,6V :D
And as you can see at
slapps.com Twinmos 3700 running at 2,8V
I think I've covered it all then;)
