    Default Solid Caps on BFG 8600GT

    Bought a BFG 8600 OC2 GT from Newegg last week. BFGE86256GTOC2FE Pictured below
    http://www.newegg.com/Product/ShowIm...2FE+Video+Card
    & a huge heat sink to overclock it.

    On the board you can see 6 Blue solid caps placed around the heatsink. Their have 180 16V on the top. The one I received has only 2 Blue solid caps, the other 4 replaced with yellow Electrolytic Capacitors Labeled M 6452U & have 5v 1500uF 2.5V150? on the other side.

    My Question is how does this affect the quality of the card? Will this affect the overclocking ability, or are Solid caps over-hyped by Gigabyte?

    Know you guys here deal mostly with PSU's, but I couldn't think of another forum that would have the knowledge of Computer/Electronics to know the difference.

    & Mr. Guru if you read this Thank You for putting this site together, made finding a PSU for my new computer SOooooo much easier.

    Just a different OEM. The caps are the same value, so your performance, OC, etc. isn't going to be affected.

    Solid caps do hold up better to higher temperatuers and will last longer... but I've yet to see "bad caps syndrome" affect graphics cards the way they have motherboards and power supplies.

    I feel it will play a role, since GPU's use similar DC-DC conversion/VRM schemes as CPU's. I can't see much from those pics, but the blue solid caps you mention may be UCC. Now, if the number of phases (count the inductors) is low, the ripple current per phase would be larger. Conductive polymer caps like Sanyo SEPC etc have almost 3x the ripple current rating when compared to the common aluminum electrolytics. So, as long as this is taken into account when designing the board, you should have no issue.

    As long as the replacement caps are solid polymer ones, it should not hurt. If they replaced them with wet electrolyte capacitors, it certainly will affect your outcome.
    Personally i do not like electrolytic capacitors on GFX cards, they don`t stand the heat and ripple very long.

    Problem with GFX cards is that memory will start heading south due to high heat, before the caps do. But I got to agree solid caps are far more reliable at high temps.

    Jonny is right they do last longer

    I got a Rage II+ DVD from 1996 with solid caps, all good
