Ace, will you give it a frelling rest already?! Seriously, if you want to know what something is, JUST LOOK IT UP! How frelling hard is it to use google?

no where outside of the navigation of that page does it mention graphics in relation to GDDR.

the PDF Spec sheet has no mention of the word "graphic" also.

Everything I've found says that the G is indeed for graphics... maybe one of our 1337er tech forum residents can fill us in on the correct answer?

TY Vindy. everything i found aswell says that GDDR = Graphics Double Data Rate RAM

Oh and would you look at that Ace GDDR is FBGA Ball Grid Array

GDDR-3 Specs from Micron

Overview

GDDR3 utilizes two key features, on-die termination and a dynamically controlled impedance output driver, to address the high-speed, point-to-point signaling and solve the signal integrity, data clocking, and power consumption problems that plague today's DRAM I/O schemes.

Designed for Speed

Clock frequency of 600 MHz-800 MHz
On-die termination
Programmable impedance output driver
Technical Features:

8 Meg x 32
Clock frequency of 600 MHz­-800 MHz
Single­ ended READ and WRITE strobes
RDQS and WDQS per byte
On-die termination
Programmable impedance output driver
1.8V (VDD) core
1.8V (VDDQ) push-pull driver
tRAS lockout
Concurrent AUTO PRECHARGE
4 banks
4K refresh
Burst 4 and 8
Sequential burst type only
Mirror Function w/135-ball package

of course it stands for graphics. But when I said it didn't did you see how fast the lazy bastard went to google? That was the goal of my comment, to manipulate.

LOL

geez guys. Do you really have to rail on Ace so much? I bet if anyone else, hell, even if I asked what the G stood for, it would get an answer. But if he so much as does anything everyone jumps on his back. Give it a rest, and get back to the topic on hand.

I will initiate the return to the subject matter with a comment about the two molex connectors, and a declaration that it might be a turnoff to potential buyers. I don't like the idea of one molex connector going to a card; it just adds to the clutter.

Its probably a pass-through, like the molex connector on any case fan.

despite one not liking the Molex connector, that was the only way to get sufficient power to the cards as the AGP Slots couldnt handle that much voltage loads. i wonder if PCI-X will be able to? cuz i myself dont like those molex plug either.

a pass-thru? why would anyone use that on a videocard?

Doesnt look like a pass through to me. But I cant even begin to imagine the amount of power the card needs to require 2 molex plugs. Even 15k rpm SCSI hard drives only need 1 afaik.

Certain Voodoo5 6000's had power adapters that could be plugged right into the wall.

Is a single Molex limited to how much power it can supply? With all the Y adaptors and passtroughs I've seen I never considered it before.

that depends on everything you have connected to the PSU, if you have a barebones system, then you get plenty of power to a VCard with a molex plug. now if your running a super stocked system, it should still run the card, but it may overload the PSU.


do the VCards take in the +12V or do they cut that down with transformers and resistors?

Of course they cut down with their own power supply from there, you think they are gonna run your geforce at 12v core voltage? How about the RAM?

Technically there is a limit to how much power you can stuff through some wires before they melt, but that would most likely burn the power supply up long before you melted the wires. Its like at the project that my brother and I were working on, he has three 300 watt light bulbs (on little lamp fixtures that say "not rated for use with bulbs over 40 watts") that are connected via a single extension cord. When someone was asking which plug went to the lights to the room, we simply told them; "Its the warm one".

i know for sure the core and RAM dont work @ 12VDC, i was just wondering if it takes in +12 for the fan or anything like that. but i guess they dont

Well, you could always pop a VOM on each pin and check...

well, i know the fan is variable so its using a range of voltage probably from ~3 VDC upto either 9 or 12 VDC

NIIICE!! lol they even put a HS on the Voltage Regulators

Wow, that's XBox huge.
