I see. I wonder why that one small change is worth a difference of $50 USD?

Which do you recommend? I'm of a mind to buy the "True" 3-way SLI, myself.

(EDIT: The one with the oh-so-horrible NF200. )

(EDIT Number Two: Wooo. I think I need caffeine. Or maybe it's jet lag. I can't seem to wrap my mind around this whole deal right now. The 760-A1 is non-nf200, correct? What is the 760?

Source of my frustrations:
Newegg.com - EVGA,classified

Now Im going to go add an energy drink to my day, see if that works.)

(.........edit 3: Reaaaaallly didn't mean to try and hijack this thread. I was rushing myself and wasn't paying attention to what I was doing. Please don't kill me? )

Calm down, catch your breath, and chill.

Newegg.com - EVGA 141-BL-E760 LGA 1366 Intel X58 3X SLI Classified Extended ATX Intel Motherboard - Intel Motherboards

That one above is the one WITHOUT the NF200 Lane Splitter chip

Newegg.com - EVGA 141-BL-E759-A1 LGA 1366 Intel X58 SLI Classified ATX Intel Motherboard - Intel Motherboards

This one above is the one WITH the NF200 Lane Splitter chip.

Be mindful, the NF200 chip is *estimated* to bring a slight(2-3%) performance hit due to added latency of the splitter. Personally? I'd recommend the non-NF200 motherboard, but frankly the diffrence is so slight, that if I flipped a coin to decide which one I ultimately ended up with, I wouldn't lose any sleep either way. (I still recommend the non-nf200 version thou )

I think it is a very good question! It's the answers that people get killed for.

I had heard that one or the other ran quite a bit hotter. Is it the NF200 version that runs hot?

No idea why it is priced higher, other than it must cost more to produce. You can kill me now.

That's a pretty big price spike for the chip. I thought originally, before X58 even hit retail, Nvidia's original plan was to sell the chips for about $10/ea? Regardless, I wouldn't touch the chip if I had a choice. Maybe in the future, when graphics cards can actually saturate a PCI-E x16 2.0 bus, this little chip might help a little. But even then, I'd be skeptical - it technically adds lanes, but those extra lanes still have to contend with the same X58 "bottleneck". Or, to look at it another way, you can double the number of chefs in a restaurant, but that only goes so far if you don't hire any more waiters.

Regardless, I believe the NF200 chip has a TDP of about 15-20W, which is a reasonably significant amount of heat to get rid of passively (although quite easy if you're willing to use a low-speed fan).

It's not just a matter of slapping the NF200 on either, the PCB is different because the traces to the PCI-E 16X slots changes on the non-NF200 board so the two 16X slots when used in two card SLI will be gapped. So you have to factor in design and production costs as well, but the majority of the cost should be the chip itself. It is only a $50USD premium at retailers is it not? And that is likely just reflective of EVGA's pricing. I'm sure we will see less a discrepancy as time goes on.

As for which one is better, I still believe the non-NF200 is the better purchase. Yes the NF200 chip does put out heat, that is part of the reason guys are getting high NB temperatures and that whole circus about it over at the EVGA forums. How much higher? Who knows as there is no way to monitor in Windows yet. And anyone who says they can give a comparison from when they were running at load and then quickly went into the BIOS to check should really give their head a shake. Only way to accurately compare is in Windows under load. Setting both boards up with the same settings in the same room might be able to compare at idle in the BIOS, but I still don't like it as a comparison. The point is, it is another heat dump into the passive cooling.

The biggest thing is that I don't see any benefit to the NF200 chip. I mean, sure, it allows for three physical 16X lanes...but with any single card today, 8X PCI-E 2.0 isn't saturated, I think that was clearly evident in my EVGA X58 review. As un-thorough as it was, it was pretty obvious that overclocked GTX 280s didn't seem to give a lick of difference if they were in 8X or 16X slots. Perhaps with GTX295s, but you only need two 16X slots anyways which the non-NF200 board gives you, and gaps them nicely to boot.

So again, the non-NF200 is cheaper, potentially cooler, doesn't have the minimal 1-3% latency hit (if it isn't more), and it offers identical performance in regards to 16X vs 8X slots in Tri-SLI with today's cards. Maybe next gen cards will saturate an 8X slot. I wouldn't bet on it though.

Am I going to sell my NF200 board right away so I can buy a non-NF200 board? Don't be crazy, they are damn near one in the same for my needs IMO. Speaking of my board, I was tasked with some light activity during a medical procedure so a couple hours benching my 920 D0 on the Classified is technically what the doctor ordered...I'll just let the screen shots do the talking, I am busy with other work right now

Actually I didn't shake my head....figured that would be "counter-productive", what I did do though was also supplement that "head-shaking" method with physically touching the Northbridge HS while it is both idle and under full P95 Load, although it was considerably warmer it certainlywasn't the "lets fry eggs" hot that others on Evga are claiming. I think this is simply because of the fans n airflow in my case,,,,the Scyth 1900 RPM blowing cool air on to the GPU's also provides a fair bit of air pushing into the NB area, also the additional" fan on the TRUE throws a fair bit of air over the VReg....my Vreg temps are about 8c cooler with that additional TRUE Fan on the backside.

Would be nice to actually see the NB Temps,...until then, I'm not concerned based upon the "touch test"..

That is an amazing validation 3oh6!

hehe, i wasn't referring to you specifically, sorry about that. i meant someone in "forum land" or "review world" that is going to post a "comparison" of the two boards temperatures using that methodology and then draw a conclusion from it for the public to get into an uproar over.

i sent another e-mail to Peter about a different topic but at the end, added the extreme wish to have NB temps monitored in Windows...again, for the umpteenth time.

No I knew you weren't referring to me specifically....but I "thought"...hey, I tried that

Anyhow 3oh...would I be far off to assume that most of those guys having Heat Temp issues on thier NB are those more or less strictly going WC with little to no Case Air Flow?

I really was expecting the NB to "feel" really hot, but was pleasently surprised.

btw..Those DO OC's are truelly amazing!!!!

you know, i thought it was simply a case of people not having any airflow around the NB like you outlined with watercooling, but last night i noticed the NB temps up to 70C in the BIOS at the end of my session when i was bringing temps back up. the NB has never been that hot before and the base of the heat sink was far from warm let alone what i would consider to be hot with a 70C chip sitting directly under neath it. so i really don't know what to think at this point.

i am doing everything i can on another board for a review right now but i am planning on some non-scientific testing on the Classified NB soon...you'll want to see it
