FurMark Returns with Version 1.7.0

You know... you're the first person I've ever heard say that... can you back that statement up?

I don't need to. Read up.

Actually, PCIe x16 slot is, regardless of generation, 66W (5.5A) at 12V and 9.9W (3A) @ 3.3V.
If PCIe 2.0 slots were 150w, which they aren't, and a card would draw >75W from the slot then imagine what would happen when such a card is plugged in a PCIe 1.x slot?

I wonder what w1zzard meant when this was made:

anyway, http://www.10stripe.com/featured/quick/pci-express-2-0.php#bw

It's 150W if you use a 6-pin PEG, which adds 75W onto the 75W pulled from the board.

EDIT: could you imagine pulling more than 75 watts from those little traces anyway?

there were times when that whole pcie power connector was a magic black box with wires going into it and nobody knew details

Or no one wants to get a PCI-SIG membership and read the 700+ page specifications pdf on pcie 1.1 and 2.0

speaking of power though, which cards are eligible for a power reading from software? My ASUS 4850 isn't.

And speaking of that page I linked, I have two molex-peg connectors that don't have the middle bottom pin, but the 3 psus I've checked all have that pin present as a +12v pin on the peg power.

I's a fact that slot power is not used for powering GPU if there's an external power connector onboard. Slot power is typically used just for powering the GDDR (vDD+vDDQ) and in some rare cases, low power secondary GPU loads, for example vDDCI on X1900 Radeons.

For example, nV GTX200 series use 15-20W of all available slot power. HD4890 uses 0W from slot.

Is this Furmark more 4800 series friendly?

I guess we shouldn't even have this website then, since everyone should have to find information for themselves :/

"PCI-SIG announces the availability of the PCI Express® x16 Graphics 150W-ATX Specification 1.0. This is another in a series of specifications that attest to the continued momentum in the adoption of PCI Express architecture as the general-purpose I/O interconnect of choice in computing and communications industries."

Some boards have the option for provinding a set amount of power to the PCI-e slots, and most limit it to 75W for board power stability. You want to really pull 150W through alloy traces? With a hot running NB, CPU, and SB in close proximity? I don't.


Specs also dont mean reality, there is no way in hell any cheap board will provide 75W to a card 24/7 without causing issues.
