The VRM Area has alot of "open" contacts. Affraid that if i put something on that it might oneday come a bit loose and short somewhere in that area.
Remember though these cards have no direct VRM and RAM cooling at all, attleast it got some heatsinks on the memory chips now smile.gif
Still, knowing me, ill probably end up cooling it someway smile.gif

Need to get that core over 1200mhz !

1. Yes

2. No exact numbers but not much to worry about [especially if you have a good ventilated case], these cards run rather cool.

Wow, congrats on your card. I had made an upgrade from a 6600LE to a GTX 260 when I was getting back in the gaming aspect of things. Enjoy your new card. ^_^

That 9800GTX would make a great folding card for someone, I'm sure.

ok ppl, now I am worried that no 7850 has VRM and memory heat-sinks. I hope I am wrong. Can anyone confirm that MSI's TF and Sapphire's dual-fan cards have or have not heat-sinks. Tnx

I have a XION Xon 700p12n 700W. It says on the label that has two 12V+ rails, one at 21A, the second at 22A. It does have two 6-pin PCI-E connectors.
So, should I get a new PSU? I'm also worried about the power consumption and my electric bill. Since the 7870 requires more power than my 6850.
I was looking at the OCZ ModXStream 600W. My budget is like $60-70.
So, what do you think? And which one would you recommend if I need to change it?

Xion psus die a lot. Keep that in mind. I've only owned one and for good reason, it died. It's not even worth my time to rma.


Here's what JG had to say.

While it is true that this unit was in the review closet for a bit longer than perhaps it should have been, I will remind you that I do remember when it came in and the truth of the matter is that the unit still would have underwhelmed at that time as well. Corsair had already been offering their HX series for months by that point, Enermax was offering the Liberty, and the engineers at CWT were already laughing their way to the bank based on the PSH platform which can be found everywhere now. And the Xion PowerReal 700W was supposed to compete with these? Not happening. It's an old platform that does pretty well for what it is, but... that's the problem, isn't it? We don't need power supplies capable of theoretical 80A maximums on the 5V, do we? We need all of that beef on the 12V, so video card makers can sell us ever more watt hungry cards, don't we?

The Xion Real Power PowerReal 700W needs to be RealRetired, I'd say.

One Day. One Day I too I will have a majestic card such as the HD7800 but, for now I'm just a poor boy with no sympathy. I only have two HD4850s cross-fired, they get the job done. The HD4850 once a majestic card at the top of it's game, now a veteran player it makes me proud I have two old but, kick ass gfx cards. However one day I too will have an HD7800 and we will shall ride our majestic graphics cards into battle together but, untill that day enjoy your new graphics cards and give them all your love for me.

Thats probably the sweetest thing i have heared about gfx cards. Well done! smile.gif



About clocking 7xxx series cards. I have also an 7950 and i have air benched couple of 7970s. They all clock rather similar and clock vs voltage go hand in hand.
Raising voltage gets you more mhz rather linearly. At leas on air/water. 1.1v = 1100mhz, 1.2v= 1200mhz and so on. Some cards do slightly better, some do slightly worse.
My HD7950 does 1270mhz on 1.3v but its asic is also only 71%. This 7850 above is 81.0% . 7950 is gaming stable @ 1.25v 1200mhz. This 7850 is gaming stable 1.225v 1225mhz.
