Okay guys, beware of XFX ATI cards right now. they are using custom PCB's that have a missing corssfire connector and a missing power phase. I got one such card :mad: Not that the crossfire is an issue, i never plan for 3 way xfire, or even crossfire in general. but the missing power phase is what worries me.

however they could have added things we don't know about. this is only for XFX users. beware. if you paid for a card with 2 crossfire connections and an extra power phase, Get it replaced at the store or get an RMA for what you ordered.

I found out over at OCN, so here's the link:

http://www.overclock.net/ati/641684-warning-xfx-5770-now-only-using.html

Beware. Currently only XFX uses a custom PCB that REMOVES features...

and the new card with less features costs MORE.

You have been warned.

More power phases is better. motherboards generally use 8-10 power phases. this helps with voltage stability and ripple. which means more stable power and more stable overclocking. take one away from a motherboard and you get a slight difference because it already has a fair amount.

Reference PCB 5770's have 3 power phases. taking one away is like taking a third of the stability/efficiency away. and it hurts overclocking

I won't be sending my card back unless it's faulty.

XFX isn't producing refernce PCB 5770's any more. most stores (like newegg) are clueless about the situation.

get another brand. Asus, Sapphire or HIS

i got mine in december. i can safely assume that i don't have this rip off, right? i just have been having problems overclocking with my card with dual monitors (in non-eyefinity though) and wanted to make sure this wasn't the problem.

figured. thanks. off topic here, but does anyone know of a fix for the multiple monitor overclocking issues? i have heard of other people having the problems too. mine is (surprisingly) only when not in eyefinity, only when two desktops are enabled.

Wouldnt do it that fast, first a few things:

1. It would be somewhat of a dumb move to trifire 5770's or such in the first place.
2. Ive seen motherboards with only 3 phases before, average is around 6, higher end boards will have closer to 10-12 phases.
3. More phases in the PWM isnt always better, if higher quality components are used then it can be better, especially if a digital PWM is used, however with that said i dont think the non reference cards are running digital pwm.
4. XFX still has the best warranty in the business by far, im sure many of you have noticed(hint- sarcasm) that all of the cards that evga sells have a lifetime warranty, taking a second look, wait, those are only 2 and 3 year warranties.

Yeah. but with what they did to the cards you might just need the lifetime warranty...
