Radeon released RX 480. (Card is Released)

[Next BillG]

On the new H97 Anniversary ASRock Boards, if you have 3+ cards it wont boot unless you plug in the molex on the board. At least that was my experience, even with USB PCI-e risers.

I confirm that, I have a H97 Anniversary and mobo doesn't boot if you don't connect the molex on the board. I'm using it with 5 cards.

At the end my mobo is fried.

This morning I checked it because I couldn't connect via SSH ... and...

The problem is like roitpls said, if you don't connect the molex in the H97 Anniversary, the mobo don't startup...

Now I'm thinking buy a H81 Pro BTC, if the mobo let's the user connect the cards without connect the molex...

Well, now waiting for a new mobo

I run H81 mobos in all my rigs and have done it for years. I have never used the molex connectors because i have always used good quality powered USB risers.

Ok, I know it, and I readed a lot of information about not connect the molex to the mobo, ... but the problem with H97 Anniversary is that the mobo doesn't boot with +3 gpus if you don't connect the molex.. a message is displayed, and it's impossible boot.

Ok, then I will buy a H81 Pro btc. I expect the memory and cpu are ok!. 1st lesson! 

Did you message say if you press the N button and it will boost and will never ask the same question again?

I don't remember if a pressed N, I don't think so. But I remember that the mobo couldn't boot, and I remember also that the screen doesn't show any messages about press any key to pass the check of molex.

I readed before about don't plug the molex connector, but as a said I couldn't boot the mobo. The rig was running about one month. Now, is too late to check if I can press the N key to pass the check. 

To me it's really important to know if it's possible pass the check pressing N in that mobo, because I need to buy a new mobo and also in the future I think we couldn't find a H81 Pro BTC. Do you have a H97 Anniversary mobo without molex connected?

Where are the settings for 29@ 120 watts?

Here...if you look closely you can make out the proper Hex values for the bios 

squeezed a few more MH out if it with some BIOS hacks

Hey,
maybe someone can explain the hex values in that picture ? Maybe that leads us to this hashrates.

Thanks

i have a corsair rm1000i

With modded 480x I think it's enough, but take into account the efficiency of the supply.

In your example, imagine that you can mod your GPUS, and each modded GPU uses about 140w.

With a 6 gpu rig, you need about 140w x 6 + MOBO aprox  940W.

Well, if your psu is a 80+ gold, that comsuption gets you a 0,88 efficiency, because you are using near a 100% of PSU power.

Half of the power comsuption of your system, gets you a 0,99 efficiency.

In other words, you can save money in your power bill, if you try to use the half part of your PSUs power!

I hope you understand what I'm saying... and sorry for my english!

you get a 91% efficiency with a rm1000i that use almost 95-100% of its power

I don't think so:

that must be wrong, i have one working at 91%

For the 1000W output power supply, it can output 1000 W, while it can draw 1000W/91% 1098W. So it still has some redundency.

it is actually higher than 1098, with mine the peak was 1200w for power in

If that is the case, then the efficiency of the power supply at 1200W for power in would be much lower than 91%.

For the 1000W output power supply, it can output 1000 W, while it can draw 1000W/91% 1098W. So it still has some redundency.

I thought that efficiency is related with the difference between the load needs and the power that you need from the wall.

For example, if you have a load that needs 100W, and you have a PSU with an efficiency of 90%, then you get from the wall 110W.

The efficiency is highest at around 50% of the maximum output. It is lower when the output is too high. I run my output around 70-80% of the maximum output.

Exactly, that's what I thought. I remember my days in the high school learning the maximum power transfer theorem, you get the high efficiency of your psu if your load is 0.5 of the total supply.

[QuintLeo]

Well, if your psu is a 80+ gold, that comsuption gets you a 0,88 efficiency, because you are using near a 100% of PSU power.

Half of the power comsuption of your system, gets you a 0,99 efficiency.

 Depends a lot on the specific power supply - my Seasonic X1250 and EVGA 1300 G2 PS2 are typically over 90% efficiency with 110v in even very close to MAX rated power out, but they're VERY close to meeting Platinum level 80+ specs (as a few review sites have noted).

 I suspect you meant "0.90 efficiency" not "0.99 efficiency" though at half rated power load - and again, that VARIES with the specific power supply as to it's most efficient point of operation, and a little on the input voltage, though 50% is usually very very CLOSE to that "most efficient" level if it's NOT actually that point, and the drop-off on efficiency above that point on current 80+ power supplies tends to be pretty slow.

The efficiency is highest at around 50% of the maximum output. It is lower when the output is too high. I run my output around 70-80% of the maximum output.

My electricity price is high. So I use the platinum power supply and also a big specication PSU, so that the efficiency is high.
