Biostar M7VIG 400 with Suspect caps, need help.

[c_hegge]

The motherboard in the title sometimes doesn't boot (freezes on the POST screen). It has the following caps:

6x OST RLX 6.3v 3300uF for VRM out
3x OST RLP 16v 2200uF for VRM in
7x OST RLG 6.3v 1000uF for everyting else

I will use Panny FJ for the 3300uF RLX and the 1000uF RLG. I can't get FJ for the 2200uF RLP. What should I use for them? Options are Panny FC, FK and FM, Nichicon HD and HE, Chemi-Con LXY, LXJ and KZE and Ruby PX. Which of these would be the best replacement?

PS. I'm not too worried if they are slightly bigger than the originals

OK, so just to confirm, the caps here http://australia.rs-online.com/web/s...duct&R=5261301 should be OK

Exactly.

EDIT: Provided the 12.5mm diameter is good.

Size doesn't worry me. Will order some of them.

Could you put up a few pics of your FJ's? There's a thread going about fake FJ's coming from OEM's and the example is an Acer board:

Looking for date codes, bung, top, and printing examples.

Also, where do you get yours?

EDIT: Fixed board brand

Here are some Pics of my Panny FJ caps. They are 3300uF 6.3v and I get them from eBay. Seller ID is egekecu. Here is a link to the store (PC Motherboard Capacitor Sotre) http://stores.shop.ebay.com.au/PC-Mo...__W0QQ_armrsZ1

PS. I only have two of these left, so I have partially re-capped the board using Nichicon HM (06 date code) which I removed from an Intel 965 Motherboard.

What do you think? Real or fake?

I don't see anything that suggests fake.

Just discoverd that I ordered the wrong replacements for the 2200uF caps. I ordered 6.3v instead of 16v Will have to order some more now

I hate it when that happens.

Finally, I got the right caps, will go and finish re-capping it now

[c_hegge]

Re: Biostar M7VIG 400 with Suspect caps, need help.

OK, I've finished the re-cap. Will stress-test it now. Here are some pics. I didn't end up using panny FJ anywhere. For the 3300uF RLX I used some second hand Nichicon HM (06 date code) and for the 1000uF RLG I used Chemi-con KZE. Also added a southbridge heatsink (not necessary but looks good).

PS. Don't try to solder outside at night. You will get eaten alive by the mosquitoes!

I'm getting frustrated with this thing now. It rebooted last night due to automatic windows updates I've unpluged the ethernet now, so no more updates!
