Zotac GT 240 Leaky capacitor?

[Valvados]

My GT 240 slowly went out since I bought it a few months ago. Only got about 30 hours of gameplay on it.

I noticed there is some drops on the under side where the capacitor is and I didn't notice that when I received it used from amazon. Do you think new capacitors will allow me to boot windows with display driver installed? I can no longer boot with display drivers installed tried many different things convinced its the gpu or capacitors on it.

Plugged into my friends mobo made it work until for 2 boots now not working again. Worked okay in his rig accept for GPU-Z was instant bluescreen or corruption. GPU-Z works now but the thing wont boot with nVIDIA drivers installed. (win7, 8 tested, WinXP showed corruption on booting with driver not sure if XP will even boot been awhile since tested.) 7 and 8 just black screen make a wierd humm sound from the motherboard or gpu not sure which.

There's several different capacitors on it theyre silver with red writing.

Is the one that definitely looks like it leaked some of the others may have leaked as well or blew, drops all over the bottom of the card possibly the residue hit the fan and blew all over.

A post I made earlier today http://forums.anandtech.com/showthread.php?t=2351915


Should I try putting some capacitors from my EVGA 5900Ultra or do I need specific voltages?

If it is only a few months old and bought from amazon can you not return it under guarantee?

I bought it used on amazon from some one, I don't think used items have any sort of warranty.

Now to late for that I've put a capactior for my evga on it still I think some of the others are bad too.





I got some pictures ill post up within the hour.

Is there not some where I can find these capacitors or better ones?

Re: Zotac GT 240 Leaky capacitor?

The FP are high quality caps not the issue.

Is there a way I can get some? Some of mine leaked b/c of the motherboard causing them to leak or age.

Re: Zotac GT 240 Leaky capacitor?

Hey guys I'm ordering the parts for a motherboard volt mod and droop mod. only 3 bucks so I wanted to order the capacitors for the GPU with it.

I have some additional info on the graphics card, I am 100% sure the capacitors are to blame at the moment however the reason why they blew was another issue, motherboard setting.

This computer will not boot into OS until the area around the capacitors are around 70 to 80 *F. The only thing I think would be affect by temperature would be metal or capacitors and the fact that capacitor juice was all over the bottom of the card.

The rig is actually pretty stable though no crashes currently sometimes stays on for 2 weeks.

16v or 1.6amp not sure, 271uF, mode name or creation time04Ad
25v or 2.5amp notsure, 122uF Model name 03Ad

Is what I could pull out of the numbers above.

I think I found the capacitor here;
http://www.digikey.com/product-detai...7-1-ND/2347917

here's 2 others that are close I guess
http://www.digikey.com/product-detai...0-2-ND/2790789
http://www.digikey.com/product-detai...3-3-ND/2294154

I'll wait to order it. What capacitor should I get 493-3863-3-ND or 493-4680-2-ND?

The ripple current is hugely different on them.

The last digit is the number of zeros to as to the last two. So, 271 = 270uF and 122 = 1200uF.

For the 1200uF caps, this is all that digikey has in stock: http://www.digikey.com/product-detai...2-1-ND/3466044. They may be a bit smaller then the originals physically, but will work fine.

One of the numbers is the voltage rating, the other is the capacitance.

In the capacitance code, the last number is how many zeroes are at the end.

So FP 03Ad 122 25 tells you it's a 12 x 100 = 1200 uF , 25 is probably 2.5v rating . 03Ad is just a batch number, manufacturing date, whatever.

FP 04Ad 271 16 tells you it's 27 x 10 = 270uF 16v capacitor.

FP is short for Functional Polymer, it's a kind of solid capacitors, which are hard to produce to have high capacitance AND high voltage rating. The higher the voltage rating, the smaller the capacitance.

In your last post you say 1.6v but that's not a standard voltage rating, it's almost definitely 16v.
Standard voltage ratings are 2.5v , 4v, 6.3v, 10v, 16v, 25v, 35v and so on.

Video cards and computer components don't generally have any reason to have capacitors rated for more than 16v because 12v is the largest voltage in PC.

Based on your last message, I'm not sure the capacitors are the problem. It could be a mosfet or a diode that's cracked or faulty in some way, or it's poorly soldered in some way, and the heat may expand the part enough to start working after a while.

But if you want to replace the capacitors, you can find them on Digikey :

270uF 16v : http://www.digikey.com/product-searc...0&pageSize=500

1200uF 2.5v : http://www.digikey.com/product-searc...0&pageSize=500

I've left 4v rated capacitors there as well, you can use either 2.5v or 4v with no problems.

Thank you sweet. Those are a bit lower in cost.

Do you happen to know if 1.5nF ceramic capacitor on a circuit board is equivalent of 1500pf?

http://www.digikey.com/scripts/DkSea...47570184002575

1.5nF capacitors were listed for the vdroop mod which brings vcore down when the cpu has a load.

Re: Zotac GT 240 Leaky capacitor?

Google is your friend: http://www.electronics2000.co.uk/cal...-converter.php

So yes 1500pF is the same as 1.5nF.

But regarding vdroop mods, if it's a motherboard with intel cpu, Vdroop is by design and it's calculated to keep the system stable under all conditions (even overclock). Using vdroop mod when overclocking may damage the CPU - it should only be used when the board has no CPU Vcore adjustments in the BIOS settings, to squeeze the last drop of frequency out of that CPU. If your board does have CPU Vcore adjustments in the BIOS, then in most cases a Vdroop mod is not needed. Also remember that C2D processors respond most well to Vtt (also called "FSB Voltage") and Vcore has less effect in obtaining an succesful overclock.

So, again, a "Vdroop mod" is seldom required to achieve a stable overclock. I have only done ONE such mod in my entire C2D tinkering adventure, and that was to stabilize a (rather silly) Celeron D overclock @ 4.2GHz. I have never needed such a mod for anything else, and i've run rather silly FSBs on yer average run-of-the-mill LGA775 mobo.

I spent all day working on the first 20mHz of the board before I realized that the e7400 is at the top end of the motherboards FSB with a locked multiplier so I'm glad I didn't order the parts and thank you everyone for your replies.

It was a lga775 board and cpu actually haha. I have liquid cooling on it and it was bugging me not having it OC'd. Oh well it's fine I paid 15 for the processor a year ago and 3- something for the video card and it runs games way better than a PS3 can.
