HD 4870 HELL!!

[SPK]

Red, u sure it's PER 12V rail, or just the amount of Amps being delivered on the 12V rails in all? Because I have a PSU that delivers 24 and 22A on each 12V rail, and the card runs stable.

[Redfish]

Well I thought was per 12V rail, I must have been mistaken as you said yours works fine.

What would you say should be the minimum Amps in all to run a 4870?

Cause it seems like you really have to make sure your PSU can handle these newer cards esp if you have alot of other stuff plugged into it.

[SPK]

I'd say for a 4870, a PSU should have nothing less than 40A to be safe. However, >60A would be ideal depending on your configuration... Right now I know I bridging my PSU's limit with everything inside this PC. Hence why I've resorted to using a 2nd PSU to power extra stuff that would be outside otherwise of the case: not the prettiest solution but it works for now...

[Redfish]

Yea makes sense, just was trying to give a heads up to help out. Thanks for clearing that up man

After recently finding out about 12V rails and how much Amps are required on a rail to have there newer gpus run problem free....what PSU do you have Saxman? and how many Amps are you running per 12V rail??

Suggested for a 4870 is 32A per 12V rail and if you want the Nvidia core 216 the required Amps per 12V rail is 36A.

Trust me, it eating most things i throw at it

^^Waw ok then Saxman Prime lol. Well guess it's a compatibility issue....bummer dude

[Kraeoss]

maybe it's your board.... heard some boards like to harass you with the  new technologies esp. abit...lol look for a bios update or something of the sort

[Saxito Pau]

^^

So I must conclude. With no funds to buy a new card, (even if i sell card, the money will quickly go to other stuff) I stuck with this till further notice... maybe if Abit releases a BIOS update problem will fix

sax have you considered selling your board and getting a relatively cheap alternative?

imho...even ah giga p35 right now will have you enjoying your larger investment in that card.

Yes I have, but there are these issues:

Who on GATT gonna buy this board with such a "major" issue (granted it works beautifully otherwise)? Especially as I pay close to US$200 + shipping + VAT for said board?

I am just not too keen on changing out motherboards at this time. It's a lot easier to install new video card than a new motherboard. Call me lazy, but that is just how I feel until further notice.

And my finances are bad at this time, so is not like I CAN change per say. The risk of being more broke than I am already while waiting for a sale is just too high.

The easiest and fastest way out (once my finances look better!) is to go back to Nvidia. GTX 260 core 216 is my target. But that is a next year acquisition at this rate.

what board is it you have there sax ?

[Netizen1]

what board is it you have there sax ?

I think he's got this: Abit IP35 Pro XE

[Arcmanov]

Funny thing though...I could not find any evidence (on da inturnetz) of 4870 incompatibility with this board.  It just seems like some really
rotten luck at play here.  Video-card works beautifully in any other system. 

I think you said another 4870 didn't work either, right?

[Saxito Pau]

Netizen is correct about my board.

Arcman is correct about the fact that another 4870, a Visiontek, did the same thing. Mine is a Diamond. My research has found just 2 'fleeting' references to any suggestions of incompatibility between board and card.
