What effect does this have on a 6970 I just purchased? - Page 2

I just got it and still looking it over, however immediately (besides the other issues), I notice that it has 1 less vrm and one less black box next to the vrm than the reference designs.

This is an image I found online. The non-ref they sent me matches the top one (black). You'll notice towards the top of the vrm section of the black one, it is missing 1 black box and 1 vrm chip. Thats exactly how it is on mine, for a total of only 7 vrm's / black boxes while the reference has 8:



What does this mean in terms of quality and performance of the card? I'm still trying to decide what to do. Kind of pissed off newegg would pull something like this. Furthermore, this card runs HOT. Could the missing vrm have anything to do with the hotter temps?

ps- also on the back of the pcb are some stickers, circular, that say stuff like "01 ok" "02 ok" 03 ok" ... anyone have any idea what those are?

thnx
The top one is the revised reference, also... at some point they changed to one less choke. Thus, you are normal... nothing to fear.

Keep it. I have a (really cheap) 6970 that I bought which is the same design (1 inductor/choke missing) and I got a 1000/1450 overclock on it with no dramas.

I could bore you with the intricacies of electronic filtering etc. but I tend to ramble.

lol thnx, guys. Feel much better about it now ... though still mildly annoyed since I already have full cover waterblocks. But if performance isn't hurt, I'll deal with it. Just out of curiousity, is there any improvement with this newer pcb design or it's pretty much the same?

Also, the only holes different are over the vrm for my waterblocks. Is it ok to drill 2 holes in the pcb if nothing is there to fit the blocks?

There might be traces there, so I would not try drilling holes.

Since you have blocks already, you might be able to get newegg to do an exchange, since you kinda got screwed over there.

^^Yea, drilling is bad on a multi-layered pcb dude.

What waterblocks did you buy? The revised card works with the v2 blocks from EK.

Btw, yer not supposed to buy waterblocks till after you've done a physical and visible pcb inspection.

No, that has to(and no offense to you), be the most lulz question in forever.
