What are you saying? Nvidia doesn't even use NF200 themselves (aka 590) lol. They use the PLX chip on the 690. NF200 is dead.

 

True. PLX is not nVidia or is it now?

What the heck or you on about?? You said there were no 4 way boards, you were wrong. What is this about PLX Tech now? What are you saying?? Nvidia doesn't have a pcie 3.0 switch, and hell they use PLX's switch. Pissed about what?

It sounds like heatsoak is an issue. How is your case setup at moving fresh air in and hot air out?

Heatsoak? If you are talking about temps getting too high, I have my GPU set so that it is almost never over 72C, even when OC'ed and at 99% usage. I'm OCD about high temps.

Are your temps over the whole board the same? These cards get very sensitive to temps when overclocked.

My CPU is at 4.5, and after a few seconds into Prime, it's at 52. I think I done Prime for an hour or two and the temps were around 63C. So yea, I would say the temps across my PC are pretty close.

Also, can having too much voltage cause instability?

Omg I started browsing different x79 boards and in no time came across the ASRock X79 Extreme11. That is one freaking serious board lordy. 4 way SLI/CFX at x16 each slot, ie x16/x16/x16/x16 zomg. MBILF!


550


Wha this thing is insane. Dual PLX chips, integrated LSI SAS = 8 more 6gb ports w/o any of that junk Marvell crap, 16 phase vrm, gold caps lol. Hmm, starts counting change in pockets...

I need to get a board sooner than later...
I'm not digging the heat issue with 3770k
I don't want to buy $400+ x79 boards
the G1 Sniper 3 is mia, no eta
the z77 ws is bloody expensive almost x79 level
I do want 4 way cfx/sli
giga x79 ud3 is 230 bucks and does proper 4 way!
microcenter has the 3820 for 230 bucks!
LOL
x79 UD3 + 3820 is 119 bucks cheaper than getting a not in stock 3770K from microcenter and waiting a month on a G1 Sniper 3.
I'm seriously thinking of driving out to Tustin tomorrow. Am I crazy?
The wife doesn't understand why here htpc rig is torn apart...
I sold the parts lol. Well, in anticipation of this move.

Yeah thats a good move with proper quadfire with UD3. There is no other way to do four cards that I see. z77 UD5H is a good board though Gigabyte stepped up with the z77. The x79 UD3 I don't know how great that is, it also doesn't have extra PCIE voltage like the z77 board has. I really think the best thing to do for me is have one 7990 and two 7970's with a z77 board with x8, x4, x4 pcie 3.0. because with the extra PCIE sata voltage connector you will be able to push higher clocks and overall the CPU should preform better than x79.

Only the G1 Sniper 3 and P8Z77 WS have PLX chips for four way action. All the rest of the z77 are gimp lane wise.

The x79 UD3 is barebones and a super cheap way into four way x79 action. And honestly for me, I don't want to pay for crap I'll never use. I don't want to OC my pc with my non-existent iphone, or use wireless off the MB lol. You know what I mean? I don't want overpowered usb charger cuz I already use a proper 2 amp usb charger, does any board push out 2 amps?

But oh that Asrock Extreme11, is insane. If its in the range of the RIVE, I would get it. RIVE is mediocre next to those dual PEX 8749 chips on the Extreme11.

I'm probably gonna go the cheap 4 way route, me thinks. x79 ud3 -> 238 + 3820 ->247 = just 75 bucks over what I have in paypal. biggrin.gif

I didin't realize these boards to SLI how does P8Z77 WS do x8, x8, x8, x8 is there latency involved ?
