We´ve published an article on a total cap swap mod over a DFI nF4 Ultra-D.

metro told me the board shows better stability with higher memory clocks, he is right now in Argentina so I haven´t been able to talk to much to him but he will indeed post his experience here.

Those look like samxon caps, G series. but are they GA GC or GD?

unless they were GA series, you made things worse.

as DFI usually use nichicon, rubycon and chemicon caps which are both proven to be top notch caps. where as the Samxons are unproven quality.

remember, its not amount of capacitance that is key, its the quality of it (low ESR, high ripple current, long life)

if you wanted to replace stock caps with better quality caps, you would need to use something like rubycon MBZ's, which are hard to locate.

ive used the Samxon GC series myself, and while they are good, i wouldnt recomened them over the stock caps on DFI boards. even my dfi nf3 has chemicon KZG caps which i would consider much more reliable.

these rubycon MBZ's? where (if i could find them) would i start looking for such animals?

stability mod's :banana: :banana: :banana: :banana:

might be worth doing to a k8n neo4 plat get it to perform closer to a nf4?

i really dont have much of a clue as they are very hard to find.

try asking in the www.badcaps.net forum, i know the owner runs a recapping business and was able to get some, but iirc it was quite a feat.

Hi, the time will be proven reliable, we see.;) Brand name's history is NOT all factors, quality is the only one way. I have sold Samxon GD and GC nearly 2 years in Hong Kong. There is no any complain.

One more news here, the top line GA will be available soon.:D

[hixie]

In what way exactly is GA different from GC?

Samxon 3300uF 6.3v GA is one of the most lowest ESR (6.5) electrolyte capacitors, same as Nichicon HZ(but never seen it in the market). As you know, the ESR is 7 for Sanyo OSCON SEPC series 560uF 2.5v(Polymers caps) only. For details spec. information, here ---> http://www.samxon.com/PDF/prodPDF_106.pdf

Have you guys looked at high-end capacitors that are normally advertised for high-end DIY amps and such? There's alot of Audiophiles that are way too rich and freakin insane about absolutely perfect capacitors. They are probably way too expensive since some of them are using ultra-pure silver and such but I'll try to find some links.

[AzraelDarkangel]

Black Gate Electrolytic Capacitors (http://www.soniccraft.com/black_gate_capacitors.htm)
For example.

I looked at alot of links, if you need 3300uf value caps there really isn't much out there in the config you need aside from what you are already looking at.

We are talking with caps about motherobards, blackgate high-end caps are not use in this area.

Thanks. I know, but it 2200uF 6.3v only, not 3300uF 6.3v

Would you tell me where is the outlook of 3300uF 6.3v? I am very interest in this.

I noticed 3300uF was rare. Very few brands have them. I'm not sure I understand your question "where is the outlook of 3300uF 6.3v?"

I mean there is any photo or product which used with HZ 3300uF 6.3v? Thanks.

[AzraelDarkangel]

This one?

I haven't seen anything using the 3300uF 6.3v version but I'll keep an eye out.

id be interested in seeing how the GA series performs.

any word on eta?

i'm also very interested...
what will you have them available?

[Demo]

In mods like these i sometimes wonder why DFI engineers didnt use the best possible caps for their board.. i mean your paying a hefty price for the motherboard and still need to mod some stuff out.. or either that the modder is more smarter than their engineers and should hire him instead =D

[Ubermann]

The price..

VictorWang modified his Intel D975XBX with new caps as seen here:

http://vic.expreview.com/read.php?27&part=2

I would like to do this as well maybe using these GA caps?

VictorWang told me I would need the following:

6.3v 820uf for pcie/ram/pci
16v 470uf for pwm
10v 330uf for others

That is all he told me. I suspect that last cap is 3300uF?

I dont know...I just wish I could find out exactly what I need and the quantity of each. Anyone have ideas?

It is mod with polymers caps (Sanyo OS-CON SEPC and UCC PS series).

I know he is a overclocker in Shanghai, China. The cost of materials is around US$60 only in our side (not include workmanship and time).

Okay, So can you answer a few questions for me?

1. What are the BEST capacitors money can buy that I could put on my Intel D975XBX?

2. I will need to know make, model & quantity.

Can anyone help me?

Are there any how-to guides out there?

1: Rubycon MBZ's
2: If you have the mobo, you can just look at the mobo and read what type the caps are. If you want to be crazy, you can do everything above 100uf. Anything less doesnt have to be changed.

I see Rubycon MBZ being recommended in this thread. This is not to be recommended because this is an obsolete product and has not been in the Rubycon product catalog for most of this year. It is replaced by MCZ with lower ESR and ZLG that has a longer life. MCZ can be found at Wai Fong: http://www.pcbulb.com/index.php?language=en

Samxon are readily available from member Big Pope and no problem has been identified with this range. When looking at solid caps note that the high capacitance values eg 2200u offer no better ESR. They are not claimed to have a longer life at 105C but the ESR value holds to a higher frequency i.e. 300Khz. Make no mistake these are very good capacitors. When considering changing over to solid caps ESR is not the only consideration, bulk capacitance is also important. It is not wise to depart too far from the original design.

I have attached two tables that compare wet capacitors.

is there going to be full cap swap mod for the P5W DH Deluxe or is the caps alredy good enough

I need the following:

(5x) 6.3V, 220uF
(3x) 6.3V, 3300uF

(19x) 10V, 470uF
(3x) 10V, 1000uF

(4x) 16V, 470uF
(4x) 16V, 1200uF

(3x) 25V, 22uF
(1x) 25V, 33uF
(16x) 25V, 100uF
(1x) 25V, 220uF

I keep reading that solid caps are the best. Can you help me find model numbers for each? Again I want the best money can buy. If this means going with liquid, solid or a combo of liquid/solid, then so be it. I just need help finding model numbers. So far I keep hearing about Sanyo SEPC and Rubycon MCZ.

Oh, and my D975XBX rev 304 Vcore caps are apparently solid Fujitsu caps (silver with red stripe). I may leave them.

[davmax]

Zorlac It really is best not to change any caps less than 470u. They are not critical.

Did you see the cap tables I placed in this thread?

Just checked you are in Spokane. Have you tried the cap source from Topcat at Badcaps?

[Zorlac]

Is there documentation somewhere that will tell me what each cap is used for on the D975XBX motherboard?

I would like to get rid of onboard sound, floppy, IDE, PS2, parallel, serial ports, etc. Not sure if there are caps dedicated to those devices that can just be permanently removed.

[dominos789]

Wow this is awesome.

rpg711, that's a cool icon.

They even have Rubycon MBZ on board. :slobber:
