Preparing for P55: Motherboards, Memory and NVIDIA

- Motherboards
Gigabyte invited us to their P55/Lynnfield press event in Los Angeles. I hadn’t been to LA since 2005. Gigabyte’s invitation provided me with an opportunity to rectify that.
We find ourselves in an interesting situation with Lynnfield. Processors have been trickling out but motherboards aren’t available in North America. We know what the model numbers are, what the price points are and even what the processor boxes look like.
For most of the past month we’ve been doing pictorial previews of the P55 motherboards that will be supporting Lynnfield. This is going to be a strong launch with wide availability.
We previewed Lynnfield’s performance a couple months ago, but what will be shipping in September will be faster than that thanks to a very potent set of turbo modes. We’ll provide final performance next month.
Lynnfield, as we all know, is a dual-channel platform. While Gigabyte’s high end P55 motherboard (the GA-P55-UD6) will have six DIMM slots, most P55 boards will have four slots. This means that the triple-channel kits we saw for the Bloomfield Core i7 parts will be replaced augmented by dual-channel Lynnfield kits.
The same voltage sensitivities apply. While pre-i7 DDR3 memory kits operated well above 1.65V, with Lynnfield the max safe voltage is 1.65V. Stock JEDEC spec DDR3 memory kits will run at 1.5V, while the lower latency/higher bandwidth DDR3-1600, 1800 and 2133 kits will run at 1.65V.
Kingston outlined its entire Lynnfield lineup for us, including a new part number decoder to make identifying kits easier:
The P55 Motherboards
The most expensive P55 motherboard I’ve heard of will retail for around $349, while the cheapest will be just under $100 (micro-ATX). It looks like you’ll have some good options around $139 - $149. This time around a few manufacturers are taking micro-ATX seriously. MSI’s X58M proved that you can easily fit a high end motherboard into a micro-ATX form factor, so we may see more of that going forward as there’s an increased focus on making desktops sexy.
We’ve done a lot of previews on P55 already so I’m just going to link to what we’ve already done here:
Out of those that we’ve previewed I’m most excited about the Gigabyte P55M-UD4. While I think Gigabyte needs to change its model numbering system, the idea of a fully functional micro-ATX Lynnfield board is quite delicious.

I agree. It's a Celeron in drag. I'm OK with Celerons if they are cheap enough, but show me someone that pays $350 for a Lynnfield/Celeron motherboard, and I'll show you an idiot. You're just better off with the real deal.My main problem with this Celeron is when it oversteps what it is, and ends up in the arena of the real i7. If it's cheap, it's a great deal, on a fine processor. But when they start making $350 motherboards for this Celeron, then you have to scratch your head and wonder what the point is. With x58 motherboards now available for less than $200, why would anyone pay so much for an x55?
I think this processor will settle into it's proper market segment over time, but, for now, I'm just confused by the amount of attention it's getting, and how expensive some of the parts are. Really, $350 for a x55 motherboard? Why?

You just convinced me you are either an idiot or a fool. Real idiots are too mentally degraded to write. I see you can write. Since most of your posts have been mostly obnoxious, priggish, based on fashionable contrarianism, I suspect the latter. One would hope your eating habits are more refined than you post habits -- that you would smell it first before you take a bite. So I will endeavor, with patience, to perhaps correct your foolishness, your proud studied stupidity.
The Lynnfield i5/i7 do not qualify as Celerons. Not by a longshot. Not for a longtime. Celerons are sub-$100 processors made from degraded cores that have been around for a year. They often have reduced L2 caches and FSB frequencies. Lynnfields start at $200, have not been released yet, have the same L2/L3 cache, operate at the same frequencies, have the same architecture, and have nearly the same performance of the Bloomfield i7. These are brand new, fully featured, state of the art processors that pack a real performance wallop.
Calling the Lynnfield i5/i7 a Celeron is not defensible. In fact, its patiently silly and irresponsable. Only a willful fool would make such an assertion. A fool who clearly does not know what he is talking about.
The Lynnfield i5/i7 is an adaptation of the Bloomfield i7 for mainstream/high performance desktop computing needs. Not for your imagined needs TA152H. The goal of this adaptation is affordable aquisition and operating costs while offering excellent performance of the Nahelem architecture.
The i7 Bloomfield was designed as a server processor to compete with the Opterons. What is changed in Lynnfield is the third memory channel and special high speed CPU/chipset/memory interconnect has been removed. This high speed interconnect is mainly useful for server/workstation applications which have extremely high bandwidth requirements that do not exist for desktop computing. The loss of the third channel and high-speed interconnect has been demonstrated to not be noticable in a desktop mainstream/high performance desktop computing environment.
I hope you like the taste of crow TA152H. Because, from Mr Shimpi's May article, the Lynnfield i5/i7 with the P55 chipset is reasonably certain to have perfomance comparable to today's Bloomfield/X58 at a fraction of the cost and power consumption.
This is the smarter choice for my money.
Lastly, do not call reasonable people idiots because they don't think like you do. Or they don't entertain the same expectations of their hardware as you do. Or are subjected to very real constraints (like money and personal responsability) than you. If you want to be effective in this forum, stop calling people idiots. It would really be great if you were more responsable with your posts

Let's not get too hasty with quotes such as "at a fraction of the cost and power consumption." Generally when "At a fraction of" is used, it means a small fraction. So far Lynnfield is looking like it will be 60-80% of the cost of an X58/920 system. We'll have to wait for final performance numbers and prices, but when the difference in price can be made up by skipping going out to the movies for a few months it isn't a life-altering event.As far as the power consumption thing goes, we'll definitely have to wait for retail silicon to see. Considering that Intel already sells the Nehalem Xeons with 95W TDPs, I wouldn't be too surprised if the current consumer i7s are less power hungry as the process matures and voltages can be dropped. The majority of the difference between 1156 and 1366 might end up being in the chipset and extra RAM.

I agree.I think the cost for a P55/Quad i5 will be 70% the cost of a X58/920 system. That is what I had in mind when I called it a fraction of the cost.
I consider a 1156 i5/i7 at 95W is pretty good compared to the 1366 i7 at 130W.
I too believe lower power i5/i7's will become available when voltages are dropped. I think 65W i5/i7's eventually will become available just as the Penrym 95W Quad Cores had 65W models.

Why don't you two get a room and get it all of your chest together. You both have latched onto this $350 pricing as if this is Intel's fault. You should be blaming EVGA and others for these types of boards, and stick to reality, which is that there will be very good boards at about $120 once prices cool down.Again, blame the AIB's that think they can sucker people to buy these high end boards, and i think EVGA is at the forefront of this crap.
Sure, i don't like Intel's general strategy with i5 over i7 much here either, but i like you two less.
TA152H - Friday, August 21, 2009 - link
Clearly, you're an idiot.I didn't blame Intel, or even mention Intel. I mentioned the platform.
I have also said the platform should be viable when the prices fall down. I have a big problem with the cost. It's too much for what it is.
Buy a book on reading comprehension, if you can understand this sentence.

Oh, come on. Why don't you just say something like "I believe that overly expensive motherboards don't make sense, given the intended product positioning". If that's all you want to say, then just say it, instead of throwing terms like 'crippled' and 'celeron in drag' around when referring to the processors themselves.mesiah - Friday, August 21, 2009 - link
James, don't feed the trolls :PBoth snake and TA have been beating there scewed view of lynnfield into the ground since the first specs came out. Then to drive their point home they try to focus on the absolute highest priced mobos, or numbers reported from locked down engineering samples. Theres always going to be companies like evga that make decked out versions of mother boards no matter what cpu they are for. The fact of the matter is, none of us knows what the true performance numbers of these new CPUs are except for places like anandtech that are lucky enough to have their hands on them. Until intel removes the gag order on performance specs we can only speculate. But based on the excitement coming from most major tech outlets I am willing to bet that guys like snake and TA will be eating their words very soon. Lets not forget that these "crippled" cpus as they like to refer to them are only missing things that are generally excepted as overkill for mainstream computing and gaming, and the things that really effect performance for the average person such as hyper threading and high clock speeds are all present and accounted for. I have a feeling when real numbers for the lynnfield i7s start showing up, alot of people who bought i7 920s are going to be wishing they waited a few more months. But only time will tell.

Thank you.Here I thought I might be the only person completely irritated by the 1366 fanboys here.

I am really looking forward to the Lynnfield/P55 launch next month. The P55 motherboard product line looks really good, The vendors have put a lot of work into these boards and it shows. For $130, a user can get a really nice P55 motherboard. And this time Nvidia/Intel are not mucking around with licensing for those who have a crying need for SLI.This launch is really directed toward advanced mainstream users who are willing to invest $600-$700 in a CPU/Mobo/Memory/Graphics Card upgrade. Four slots of 8-16GB of DDR3-1600 memory is more than adequate for mainstream usage.
If everything holds true with Lynnfield/P55, then i7/X58 performance is available for about 70% the cost.
