ABIT IC7 – IC7-G – IC7 MAX3 ALL in one Modifications - The way to go!

I am about to do the cap mod on my IC7-g and just recieved my caps. The thing is I ordered 6.3v 2200uf Ultra low ESR caps but they set me 10v 2200uf Ultra low ESR caps. Will these work fine or will they mess my mb up?

They should work fine, but they might be slightly bigger than the 6.3v caps.

Thanks alot, they work fine. Not much of a gain though :(

Hipro, thanks a lot for the guide, they're awsome. Also, I have couple of questions:

1. Instead of using the through-hole caps, can I use SMD caps with same specs and better quality? If it's okay to use SMD in replacement, can I use smaller 0402 caps or have to use the 0603?

2. The modwires, you mentioned to use small wires, would the 30awg be okay? (they're very small, smaller than the ones in the pics - 26awg I believe?) And for some mods where it'd require bigger cable to feed the current to Vmem (one of the last mod you shown), what gauge size should I use?

I'm asking these question is because I have a lot of access to SMD caps and microscopic soldering equipments, therefore, I'd try to see if I can keep it as clean as possible.

Again, thanks for an awsome guide. :)

Can anyone tell me where i could purchase an input choke from the uk for one of these mods?

i managed to wreck one attempting to remove it from a dead mobo and dont particularly fancy my chances at attempting again.

ive looked on RS, but couldnt find anything looking similar

On this subject, ordered some capacitors for these mods and they sent me the wrong ones!

the ones i have recieved are a couple of 63V 2200uF Caps (ordered 6.3V), 3 16v 2200uF (should have been 1200u-M(?) :rolleyes: ) and 8 35v 220u-M caps (should have been 6.3v and 2200uF :rolleyes: )

im guessing that for the most part i cant use these? not too impressed with this so far tbh

great guide. did the VTT and found a droop mod for my ic7g

You only need the 6.3V 2200 uF caps soldered paralleled to the ones onboard, coz they are filtering caps for the vcore. I say hipro5 knows best and just follow the guide he made :fact:

sweet... so your saying that as long as theyre capacitance is 2200uF theyre fine? the fact that the voltages are all higher doesnt mean they cant be used for this?


*sigh* all this coming from someone with engineering qualifications as well :rolleyes: too out of practice

2200uF 16V is bigger than 2200uF 6.3V. That's the only difference I can think off and one of the most important things are the max temps and the ESR of the caps.....

With the 6.3V 2200uF caps, you can still solder them behind the mb without hacking the back of your case :D

heh...was gonna hack up the back of the case anyway :D

while i think of it - the choke for this - i dont seem to have a spare one i can use.
is there anything specific to look out for? or is it just a ferrite core of some kind with a relatively thick wire wrapped round it?

Are you in the UK? I've got a few spare here which I've removed from dead boards. Drop me a PM if you want me to post you one :)

wicked mate, will do

anyone? Hipro?

I wonder why I don't get e-mail notifications about this thread!........ :(

You're welcome..... :)

You can use as tiny SMD's as you wish and can handle of caurse.......Only think to been taken care off, is to be in specs......For example, you must not use caps with less voltage than the one you have on your circuit ........

2. You can use small wires for the mods......Not to much current drow.....BUT for the Vdimm and the VTT, you HAVE to use a bit thicker.... ;)

gotcha, so I can use SMD parts with the same specs? I was worried about the mods since like the Electrolytic capacitor mod, you mentioned that it needs to have high internal resistance, that's why I was worried if I need a really BIG cap. I'll try it with the SMDs, hopefully, it'll come out nice and clean. :)

You must have misunderstood something here. You sure don't want to have high internal resistance, but indeed the exact opposite. What you should be looking for is an ESR that is as low as possible. ;) You sure can use smd parts if you can find some with the same specs.

But please don't use high ESR parts. :)

That's what I thought, and the reason why I got confused. Because on the guid, Hipro mentions that. At my company, we have some good quality parts, so I think that I"ll be good.

Btw, why shouldn't I be using ESR parts?

Oooopppsssssss............I just noticed that part of the capacitor..........It must been writen wrong when the translation from Greek to English took place.........I'll tell the guys to correct it.........and yes it is LOW ESR electrolytic capacitor........ :)

Do me a favor and read my posting one more time. ;)

Everey capacitor has ESR (an internal resitance).

The emphasis was on "high ESR in the last line of my previous posting, quoted above. That's to say, you should use low ESR parts. :)

Thanks bro, I must be on drug that day :slapass: . I thought of you saying that ESR is a type of Capacitor because these SMDs have different rating (from Extremely good quality caps to low quality caps - which I'm not familiar with the types and their names); that's why I mistook the "ESR" as a "good type" capacitor and not ESR as its definition.

Thanks. :) I'll try these out :)

Last before I commence the project. Are these all the parts needed for these mods (beside the extra stablizer at the end? Please help me double check

ELectrlytic Cap (I choose to go with SMD)
3300uF - 6.3V

Vagp
10ohms SMD
200ohms VR (25 Turns)

Vdd
50K VR

Vmem (Vdimm)
10ohms
200ohms VR (25 Turns)

Vtt
10ohms
200ohms VR (25 Turns)

THanks

Everything seems OK.........exept that SMD 3300uF/6.3V......How are you going to solder it?.......
