    Default Gtx 590 ...poor design..!!!!!!

    Here is a small review OF GTX 590 poor design

    KitGuru has discussed problems with Nvidia’s GTX590 flagship before, but the reports continue to filter across various forums that some are still failing. We all love a good story, but sometimes it is important to really find out what exactly is wrong.
    KitGuru reported before that respected website Hardware.fr analysed the GTX590 with a thermograph.

    Their GTX 590 Testing showed a reading of around 112c under load. Since we reported on this, our readers have been filling our inbox with comments and views on the matter. Some partners have been updating card bioses to supposedly help with power delivery however the main issue is apparently down to a poor VRM design. The very high temperatures are due to the VRM’s being underspecified. Each of the GPU/IMC phases has 35A each, and only four phases per GPU, with one phase for the IMC.
    With the DrMOS chips being operated at close to peak forward current rating with a high duty cycle, this is part of the reason of the stress related failures. At very high load levels the DrMOS chips can become very inefficient as they are optimised for efficiency at low loads. Some claim they shouldn’t be used for VRMs for high power electronics in the first place. This inefficiency is adding more wasted heat into the scenario. Nvidia have placed them right under the fan’s dead spot too which doesn’t help with cooling.
    Why wasn’t this a problem with the GTX580? Well this card was complimented with 6+2 power phases and the design is dramatically different. It looks as if the bios changes might not be the cure, and many people will be best waiting on third party custom designs from companies such as ASUS which will rectify the poor design aspects of the latest Nvidia flagship card.

    lol. I think those were few gpus that explodes. nd new bios will fix it as nv said. Bt i think after new bios n new driver, it can match hd 6990 in any game. N the POV/TGT GTX 590 ULTRA CHARGED is the fastest dual gpu. N it has no issue till now.bt price is high.n beats hd 6990 oc n gtx 590 oc by a good margin. N personally my bet goes for custom partners.same for the amd counterparts. Custom partners can bring any gpu to top each other.

    You may be able to compete the 6990 with new driver and new bios on nv 590...I guess red team wont be waiting to see that.....they will also competing nv 590 with their new bios and driver.....But the prob is with the hardware design... I wonder how they will solve those problem(Mentioned Above) with bios and driver.... We have to wait until other vendor like ASUS comes with a solution....
