AMD 10.12 vs 11.1 vs 11.1a tested ... interesting read

[apoppin]

I thought you left? Or are you just back to continue twisting the argument to remove the egg from your face? Once again, the argument was not what benefits/improvements the 8-pin PCIe connector offers over the 6-pin connector, it was that the 6950 being fed by two PCIe 6-pin adapters still gets all the power it needs. Learn to read.

Same back right at you; if you are talking about me, you have splattered yourself with a dozen eggs. You have no argument. Perhaps you should go back to school.

i have provided facts and links while you quote yourself and other anonymous forum posters. You refuse to explain yourself when called on it.

There is a definite danger in flashing a HD 6950 to HD 6970. What you don't know is if the lack of the 8-pin has anything to do with it or not - although you are pretending you are some kind of an expert.

Perhaps AMD will respond and clarify it for us.

Right, YahooAnswers is so definitive

You refuse to explain yourself when called on it.

What, like all of these:

I kind of figured since I didn't quote an "expert" (read: someone else on the internet with half a semester of electrical engineering and an ounce of commonsense) you would take that as some kind of "victory" or "stalemate." Here's a link that specifies more about PCIe connectors and their capabilities: http://www.tomshardware.com/forum/274631-28-power-spec-power-plug . Now quit dragging yourself through the mud just to waste my time.
Thank you; unfortunately some people just don't get when to leave.

From MrK6's link (http://www.tomshardware.com/forum/274631-28-power-spec-power-plug)

So according to this the 6 pin connector is 2x12V and 2xGround with one wire used for detecting the plug, while the 8 pin is 3x12V and 3xGround with two wires used for detecting 6 pin or 8 pin plugs. I don't have many power supplies with 6 pin PCIe connectors, but all of mine have three 12V wires, so I found this strange. However, it seems very obvious that the specs on the PCIe connectors are extremely conservative. According to the quoted post, the max rated current for the 8 pin connector (12.5A for 150W) is barely over the max rating of a single HCS molex pin (11A).

Having more wires and leads reduces the resistance and heat but is the heat significant? The resistance of a 2ft long 18 gauge copper wire is 0.01277 ohms. For example, if three wires are supplying 12.5A and three are returning 12.5A, 1.33W of heat are generated by the wires if the cable is 2ft long. If there are only two wires supplying and two returning the heat goes up to 2W. The amount of heat generated by the connector itself should be much, much smaller.

Another thing is that 8 pin connectors are designed to accept 6 pin plugs and can detect the difference between the two. Video cards can be designed to operate differently depending on the type of plug connected, refuse to operate at all, or operate the exact same way. How does the 6970 react to a 6 pin plug? Does a flashed 6950 know that a 6 pin plug is connected? Does it make a difference?

From what little I've read it doesn't look like the connectors themselves really matter. It is clear that the 6 pin connector can handle more than 150W. It looks to me that any limiting factors should exist on the card after the power connector, and those details probably aren't available.

It seems like we simply can't dumb this down enough for you.

There is a definite danger in flashing a HD 6950 to HD 6970. What you don't know is if the lack of the 8-pin has anything to do with it or not - although you are pretending you are some kind of an expert.

It's been explained to you at least three times in very simple terms how the physics work. If it's over your head and you can't admit it, that's your problem, not ours. You have not supplied a single shred of evidence besides repeating the PCIe 2.0 specs ad nauseum. You have not clarified how the PCIe 2.0 specs affect a 6950 card at 6970 specs, you have not clarified why you think two 6-pin plugs cannot provide enough power to a flashed 6950, and you have not shown how this factors in to the documented 97% success rate of flashing - http://www.techpowerup.com/articles/overclocking/vidcard/159.

Right now you're hanging on to "AMD's response" as a last hope to save face. Some desk jockey intern will eventually get back to you with a directly quoted specification from the user manual that you will somehow transform into a glorious revelation. Absolutely ridiculous.

 

[apoppin]

i gave you plenty of links and reasons why a 6-pin connector is inferior to an 8-pin and all you have responded with is ridicule. You are no expert and it shows. You have not replied to any of my direct questions to you.

Sadly, it seems like we simply can't dumb this down enough for you.

It's been explained to you many times in very simple terms how engineers designed the PCIe spec. If it's over your head and you can't admit it, that's your problem, not ours. You have not supplied a single shred of evidence besides repeating your mantra that there is no danger. You have not clarified how the PCIe 2.0 specs affect a 6950 card at 6970 specs, you have not clarified why you think an 8-pin plugs is unnecessary to a 6970, and you have not shown how this factors in to what happens AFTER the documented 97% success rate of flashing.

i have met many of the guys at AMD at events such as CES as ABT is a media partner with them in good standing. We are invited to their events and we get their HW under NDA. They correspond regularly with our editors and they answer ABT forum's questions.
:thumbsup:

Where? What "direct" questions? You run your mouth and say you've said things without actually doing so. Quote said questions or re-type them right here.

Deflecting almost makes one look like he's not a hack that doesn't deserve to be posting on a tech website, never mind writing for one

Again, some desk jockeys. Anyone who means anything could trip over you and wouldn't know the difference. Give me a break.

So all you have is ridicule and personal attacks?
:thumbsdown:
John Swinimer and Asif Rehman didn't trip over me and i also know some of the guys who write their Catalyst and Fusion drivers. Yes, they all have "desk jobs". They are not clueless engineering students and i respect their work and knowledge.

LOL, I love the preemptive denial. So even an official response from AMD won't shatter your illusion.

I think even if you had the CEO of AMD walk up to him stare him directly in the eye and tell him he is wrong.............he would probrobly say that it wasn't the CEO and was a Nvidia PR spy telling him the wrong answers because physx is worthless.

 

[evolucion8]

Well done Wreckage and HappyMedium, acting like a bunch of teenagers on mid school, that's some grow up attitude there....

[3DVagabond]

LOL Yes, let's wait for someone from AMD to tell us to go ahead and unlock our 6950 instead of buying a 6970. Talk about a loaded question.
