Is that MSI card you have the 'MSI gaming' with default core clock of 1050?

I was considering those, since this guy gets 820kh/s from them.

Yes its MSI gaming card, I have tried his settings, I don;t know why, but I am getting 600Kh/s using his settings...

Considering the fact he has 67C on one card and 80C on second I am assuming its just a fake..

Thanks for the info. Why would anyone fake this? That's just plain stupid. But anyway, I'll consider it with my purchase.

I don't know, maybe he works for MSI
Maybe it requires some tweaking with BIOS or something like that, but I couldnt get past 750 on my MSI card. And it gets hot faster when I set all fans to 70%

There are some advantages of working for a big corporations. My fiancee for example works as an accountant for the power distributor we are getting power from. They do give 90% discount for everyone  who works for them I think. Or up to 100% depending on Your position there. I do have a nice -90% tho, so power usage is not a big concern for me

I played abit with the script settings for ya, this is the result for less than 1250W for all:

GPU 0 - MSI Gaming Twin Froz
GPU 1-3 Sapphire Toxic


EDIT:
Settings same as in previous post, but memory down to 1500 in all cases, gpu-engine: 1050,1086,1086,1086
all fans at 55

Guys, please be carefull with tweaking Your card. I think I pushed it too much, or GPU was bad since the begining(always had some higher temps than others). I found my card dead recently

Replacing it soon, maybe I will try some cheaper one, like Powercolor and see how much I can squeeze out of her...
