MSI GTX780 Lightning due 07/08/13

8 Pack said:
The old dominators are poor on cold sadly. Not great at all!! No TWL 7 at 2600 kills it and no Cas 7 either!!!

For X79 though on air cooling they do well like 7-11-7 2400 I think or 8-12-8 still tight enough to ruffle some feathers.

Those Ripjaws I think are still old Hynix which means they wont do much more than 2500 at anything like good timings.

Yeah, they are the older EOL ones, I managed to grab one of the last kits! They've done me well for a £70 kit :p They'll only be going in with Ivy E to see at what point the timings drop off.

Always had an urge to try out some TridentX's though, especially the 10-12-12-30-2N 2666 kit :cool:

Either those or feel free to recommend me a decent PSC kit ;)

Maybe he's waiting for msi to screw up again tomorrow before advertising it at a special pre order price :p

As I posted on OCN if MSI take much longer with the 780 lightning it will be coming out at the same time as the HD 9970 lightning.:p
 
lol :D

Probably not too far off with that!!

I'm going to begrudgingly sitting tight until the 25th as thats when I get paid, so I can use this months wealth on other bits I could do with, like primochill rigid tubing :D
 
I have a feeling nothing is going to happen today, Neliz hasn't been seen since the 7th and all we have to go by is the facebook comment by MSI's marketing team of doom.
 
Think they will have worked out by now their target market is not a bunch of kids and would have responded much better to a little factual info than teases !

I'd hope so, for MSI's sake, they've lost a bit of respect from many enthusiasts over this.

This is worth a read ;)

A good read, that PCB is absolutely HUGE!! Basically all the Classy needs is a bios with a higher power limit and the Hydro Copper blocks (due 4-8 weeks!!) to come out. Though a water block will reduce power consumption too so...

Impress me today MSI, balls to this 'NDA' crud, you have nothing to keep disclosed, your competition has already delivered...

No My friends that's Amps (coulombs per second)...about the same as your car starter motor takes and all going through a little square of silicon :eek:

TBH, very surprised people have not given things like this much thought ;)

The only seemingly Impossible, is control the heat at those microscopic junctions and they will take it.. Heat is electronics no1 enemy.

well you were wrong weren't you, it was watts not amps

Its all way over my head, my electrical knowledge has been sterilised by years of ~115v split phase work :p

It's pretty simple, Volts x Amps = Watts so the Watts divided by volts or amps gives the other. Example, 100 watts can be generated by 100v @ 1 amp or 100A @1volt
So back the other way I have a 100 watt power supply set at 5 volts....I can pull 20A as 5V x 20A = 100w

Back to the Saga, I still hear no thunder :D

Actually it was me who was wrong, as I was talking about amps from the PSU.

If not mistaken, Jakus was talking about the amps the gpu draws/generates internally.(excuse my poor terminology)

Yeah, its pretty simple and frightening, If you start off with a big power supply you don't generate the voltage you intend to use If its very low, like CPU/GPU because a. you would require massive cables (even a stock CPU) pulls 50~100 Amps
b. you would have a massive problem with voltage drop/variations due to the conductor varying resistance due to the heating effect of the current.

So we feed the cards 12volts and it's locally regulated down to the core voltage, we can even send a sample of that core voltage back to those regulators so they can constantly vary their output so the core sees a nice constant voltage.

So once at that core that voltage is low but the current is massive.

Oh I understand that part, just struggling to get my head around the core amps, I would have thought current/wattage would all have been taken from the 12v supply the card is fed rather than it being a whole other calculation as the cards TDP is rating against 12v.
