m860tu support for more than 4gb ram

can the m860tu support more than 4gb of ram?

 

based on xotic's and rkcomputers sites it supports only a maximum of 4GB

 

ahh. im just confused with PCMW's site because they have an 8GB option there.

 

It supports 8GB, but not every company offers the option as it's nearly a $1k premium.

scourge18a got 8GB from Eurocom.

 

Any laptop with the Intel P45 chipset, which includes all Centrino 2 laptops, that has two memory slots will support 8GB (2x4GB) memory, except that with the overhead they can only address about 6.8GB for use by your applications.

This option is generally not advertised because:

1. Very few people can get any benefit from more than 4GB

2. As has been stated...2x4GB is VERY expensive. Generally around $800 (see http://www.crucial.com/search/searchresults.aspx?keywords=8gb 204-pin)

 

Which is better configuration, 2x2GB RAM or 1x4GB RAM for Windows Vista Ultimate x64?

 

having dual sticks of the same kind will enable dual-channel mode... which does give a performance boost... but not really significant.

either route would be near the same.

 

I would go with 1x4GB. You'll loose the dual channel performance but thats barely noticeable to be crying about. But you'll gain an extra slot to upgrade for more memory if your laptop is capable of.

 

Ah that's good. How about using 1x4GB 1333MHz and 1x2GB 1066MHz at the same time? Would that configuration give me some disadvantages?

Currently I have 2x2GB 1066MHz in my laptop, but PCMW will send me a 4GB kit for the error they've made. This is for the M860TU so I'm thinking that the chipset is only supporting the 1066MHz, but either way it would be better if I still use the 1333MHz even though it will downclock it right?

So I'm thinking if I would request a 2x2GB 1333MHz or 1x4GB 1333MHz from them. If I go with the 1x4GB 1333MHz, I can use it together with one of the 2GB 1066MHz that I currently have, but as I've asked above will these present any disadvantages?

 

I'm not sure why PCMW offer 1333MHz with that laptop that won't utilize all that is beyond me. But heck, take it if its free. It could be use for the future when other laptops start using that speed. The only disadvantages mix matching speed is that it will downclock both ram to the one with the lowest speed.

 

1 stick of 4gb ram is expensive compare to 2 sticks of 2gb ram.

 

2 sticks of 2GB. 4GB is plenty of RAM today. Why waste performance and give up dual channel, and spend more on the single 4gb stick? It doesn't make any sense to run 1x4GB versus 2x4GB.

 

But if PCMW sends me the 1x4GB stick, I will be utilizing a total of 6GB RAM. So which config is better:

1.) 2 x 2GB 1333 MHz

or

2.) 1 x 4GB 1333 MHz + 1 x 2GB 1066 MHz (the laptop will downclock it to 1066 right? But 1066 is the highest speed that the mobo of the m860tu can support correct? So either way, I'm not losing any performance with mix matching the modules correct?)

??

About the price, don't worry because PCMW offers it for free since they were the one liable for the error they've made.

 

I'd go for the 6GB. The main reason for using 1333MHz ram is that it often has better timings than native 1066MHz when run at that speed. Also it overclocks better if you are OC'ing via setfsb.

 

So what you mean is that the even though the 1333MHz ram is downclocked by the laptop to 1066MHz, it will still offer better timings than when a 1066MHz RAM is originally used?

 

This is often the case yes. However, if you used the 4gb1333 & 2gb 1066, it would default to the slower timings .

 

Meaning i would experience the original timings of the 1066 RAM?

 

yup

Ok, thanks again for the info.. I will try to convince PCMW to give me the 1x4GB, lol. Regarding the GTS and GT, do you think the difference is negligible in terms of performance?

 

The difference is minimal, if you can get hold of a GT, it is better, but usually more expensive, and now difficult to get hold of

 

In what aspect can you apply the difference in power of the GT?

 

a few extra fps in games (1-2fps)

 

and that's barely noticeable right?

 

Right, it's barely noticeable, but some insane nuts might care about it (such as the benchmarkers on these forums ).

As for the 1x4 1x2 gb or 2x2 gb, the 6 gb sollution would definately be superior, but a 1x4 is (of course) much more expensive than 2x2 gb.
I was a bit in doubt whether to go for 1x4 and 1x2 gb or 2x2 gb when buying my new computer, but I went with the 4 (2x2) gb and to be honest, I've never gotten close to using up all the ram.
It could be useful for very ram-stressing tasks such as virtual desktops, but if you're not gonna use it for more than running a game like Crysis, having a lot of windws open and browsing the internet at the same time, you'll be all fine with 4 gb. Good luck with it anyway!

 

There still haven't been head to head benchmarks which prove the GTS is so close in performance to the GT.

 

so u mean that the GT is way better than the GTS?

 

No, I mean it's often said that it's within 1% of the GT, but no comparison benchmarks have been run to confirm this statement.

I mean tests between two identical M860TUs, where the only difference is the graphics card.

 

Ah. PCMW, they just gave me a GTS but I ordered a GT card and they said that the GT was making the laptop lock-up and producing some heat issues which I do not believe. And they said that the price of both cards are the same which I also do not strongly believe since the GT is about $200 more expensive than the GTS.

 

Yell at them, they are not the same price nor the same card. You should be getting at least $200 bucks off or your GT put in there like it's supposed to be. No one else has troubles with lock ups or heat. Or cancel your order and get it elsewhere if you can handle waiting even longer. I would be pissed.
It's not a big differece at all between the cards, but you should still get what you order and pay for. I would be pissed.

 

Well ,they give 2 years extended warranty. So I have the 3 years diamond protection right now. Is that fair enough or am I losing significant performance?

 

It's not much of a difference in performance. If you are unhappy you can OC that card just the same as the GT. I just wouldn't be happy being lied to.
As long as you are happy in the end that is all that matters. And I am sure you will be once you get your lappy. Have fun.

 

Currently, I have 2x2GB 1066MHz RAM installed in my lappy. PCMW has sent me 2x2GB 1333MHz RAM since that was the one originally in my order, any day now I'll have the RAM.

I know that the M860TU only supports up to 1066MHz RAM. When I use the 1333MHz RAM, the board will just downclock it to 1066MHz.

Question is, which of the two configs will I use? Will the 1333MHz RAM be of advantage over the 1066MHz?

Because I'll be selling the ones that I'm not going to use, lol!

 

use the 1333mhz RAm..by the way is the ram kingston,ocz or corsair?

 

You can check the memory timings and use the faster one... though you might not notice the difference..

Or sell the 1333MHz RAM if you think you'll get a lot more for it.

 

what is the reason of using the 1333?

the installed RAMs currently is Crucial. Are those good?

the brand of the one to come i have no clue.

 

how can i check the memory timings?

 

is it also advisable to get an intel turbo memory 4.0 now?

 

You can check memory timings using CPU-z, or by searching the model of the RAM chips on the net (you know, so you might not have to pop the 1333MHz ones into your computer to check).

Not sure about Intel Turbo Memory, I live in the Carmel age , I've heard that it's gotten a lot better in it's latest incarnation.

 

which one there? memory tab? and then what?

 

Lower numbers is usually better, you can compare to the chips when they come in the mail or if you know the model.

Most people probably won't notice the difference.. and IMO it probably doesn't really matter.

 

Ahh. Alright, thanks!

 

Hmmmmmmm....Kingston are very good.I like OCZ becasuse they use lower voltage and more reliable.At least this is my belief :S

 

I have 2x2GB Crucial BP112Y1.MX
CT256664BC1067.16SFD 2GB
204-PIN SODIMM 256MX64
DDR (1066 MHz)

and

2x2GB Samsung M471B5673DZ1 - CH9 (1333 MHz).

I know that the motherboard of the M860TU supports up to 1066MHz only but will there be advantage if I use the 1333MHz RAM? Better timings and etc.? Please consider the brand if you may. Thanks for the help.

 

There will not be a performance increase, since the 1333 chip will have similar/identical timings to the 1066 chip when running at 1066.

 

not worth the trouble getting the 1333 mhz if your mb dont support it.

the ddr3 if i remeber correctly, comes with higher latency.
i heard that the performance advantage seems to be minimal.

 

yup, no performance gain from the memory speed difference.

 

Even with the slightest of things, the 1333MHz is not better compared with the 1066?

 

Unless you plan on overclocking your CPU there are absolutely no gains from from having 1333 RAM in the M860TU. Unless you consider burning money a gain for some bizzare reason.

 

But using the 1333 RAM will have the same effect as using the 1066 correct? No downfalls or anything?
