Asus ROG G551

How do you think to change vga (what about cooling if it anyway posibile to change vga) i beliv that is more cheaper to find a laptop G551with spec I post so dont se how you do that?!?

 

Well if you're spending more just to get more ram or vram it won't matter, since the VGA is the bottleneck. I'd either get the config he posted or go with a sager np8651/clevo p650se (with a 970m).

 

The GPU is soldered on this model so yes you can't upgrade it later.

 

Get the Sager NP8651 with a 970M.. Base model with 4710HQ, 8GB RAM, 750GB HDD + 3GB GDDR5 970M is 1250..

 

No can't do that!
But there are more powerful models G551 as my example

That's what I say, but there are more powerful models G551 as my example that with no problem play all modern game at high and ultra so you think getting this model with 4GB DDR 5 vram and 12GB ram

 

The 860m with 2GB gddr5 and 4gb gddr5 will perform the same and will still be under half the speed of the 970m.

 

Maybe(still not shore about that) but Im playing on my model with 4Gb DDR5 all modern game at ultra and high(if there are no ultra sett)! You see that the dude already decided so that there is no point to discuss further

 

Like I said... More vRAM and RAM won't do much difference for dollars paid... If he wants a better config than the one he posted, he should go with the NP 8651. The only reason for not doing that would be budget.

 

It's a heavier machine, you do have to cool the more power hungry chips after all.

 

Is G551 just a rename laptop N551? Sr for my bad English

 

Good I'll come back next year. Nah, honestly 860M is really good value. 970M as well. I can see laptops in heavy use lasting around 3 years. 970M should run games at least with min/med settings next three years.... until some GTA6 and 4k Skyrim2 comes out.

 

The next x hips should be arriving soon with some interesting options.

 

I have recently bought this model and i am very pleased with it but i would like to know 2 things if anyone is kind enough to guide me:

1) Why doesn't live update doesn`t find any drivers for this model, even before/after installing chipset drivers and atk package ?
2) Are the drivers from the asus general driver support page compatible and ok for my laptop ? - some or most drivers from the official g551jm product page are one or two versions behind the ones on asus general driver support website where all the versions for different parts are listed

Thank you in anticipation !

 

1. These drivers rarely receive updates.
2. If they are compatible then they will work and eliminate the yellow bang, otherwise they won't. Additionally, certain incorrect drivers can cause BSOD but it is rare.

 

Thank you for the information, i asked this because the audio driver on the g551 page makes the laptop believe it has a subwoofer and volume control for it, while the ones on support.asus.com, the latest version(7409) are working perfectly.

 

Realtek audio IC is widely used by a lot of manufacturers, and their driver is universal which will work on any brand.
But some driver pack contains extra goodies and some don't.

 

Hey Guys! 1st post here.

I'm a little confused - maybe someone can help me out.
I just purchased the GL551-JK from this german website: Asus GL551JK-CN126H Gaming-Notebook 15,6"/ i7-4710HQ/ 8 GB RAM/ 1024 GB SSHD/ GeForce GTX 850M (4 GB) / FULL-HD/ Windows 8.1 bei notebooksbilliger.de

Sadly it comes with an GTX850 4GB DDR3 although everyone seems to have a version with GDDR5 and a GTX860 - so way better performance , right?
After searching the web for a while I believe that the difference lies in the model number. Every "JM" version seems to come with an GTX860 whereas the "JK" comes with GTX850 , however still GDDR5.

Does anybody know why you can't purchase the "JM" version in Germany or any version with GDDR5 or GTX860? Even the higher priced GL551 JK ( Asus GL551JK-CN234H Notebook / 15,6" Full-HD / Intel Core i7-4710HQ / 16GB / 1TB + 128GB SSD / GTX 850M / Windows 8.1 bei notebooksbilliger.de) only comes with 4GB DDR3 GTX850. That doesn't make any sense to me.

 

Dont know mate i bought mine in Serbia through Hungary and it come with 860 4GB DDR5 vram model is " ASUS G551JM-CN013D". You should better ask before buying a ddr3 is low for new game however ddr3 wil play all modern games but at medium unfortunately!

 

That sucks... .I don't understand why they don't sell JM in Germany. Is DDR3 a big difference compared to GDDR5? I read something about 20%...

 

Just ordered one of these. Was choosing between this and the Y50.

 

It is a fairly large difference, you read correctly.

 

GDDR5 is faster than DDR3.
DDR3 is mainly used for the system.
GDDR5 is mainly used for the discrete graphics.

 

GDDR5 is only used for discrete graphics in PCs (the PS4 is the only exception in other applications), DDR3 can either be used for system memory or partnered with lower end GPUs.

A CPU prefers DDR3 due to the lower latencies (lag between requesting and receiving the data). GPUs mostly just care about bandwidth so this advantage is meaningless, DDR3 in this case is a cheaper and less power consuming option.

A system can ship with either DDR3 system ram and separate DDR3 GPU ram or DDR3 system ram and GDDR5 dedicated Vram.

 

Is there a difference between g551 and GL551?

 

Yes the GL551 is a less speced version of the G551...

 

Yes it's the "lite" version of the G551.

 

Differences being IPS and 4GB 860m on the G551?

I know the advantages of an IPS display, but is there a huge difference in performance with the 2gb and 4gb 860m? I'm in the US so i'll be getting the gl551.

 

20-30% performance difference.

 

hmm that's more significant than I thought.

 

Well the 860M with GDDR5 has higher clocks and much higher memory bandwidth (over double) compared to the 850M with DDR3, the 850M with GDDR5 is much closer.

 

Hi, I got the G551JM with 1TB SATA HDD + 24GB mSATA SSD (SanDisk).
Can someone explain to me how to setup the SSD for caching? There are some Intel Rapid Storage Technology drivers on Asus support site, but without setup.exe, and I cannot get the RST GUI which I've seen around on the internet, from within which the SSD caching can be enabled apparently.
Does someone have the same specs with factory preinstalled OS to tell me how the SSD caching is set up, or does anyone know what should I exactly do with the provided support software from Asus to enable SSD caching on Windows 8.1?

Thanks

 

Unfortunately, the HM86 chipset isn't capable of doing SSD caching due to chipset limitaiton, see below document and look for Intel Smart Response technology.
http://www.intel.com/content/dam/ww.../product-briefs/mobile-chipset-hm86-brief.pdf

Regarding Intel Smart Response Technology:
http://www.intel.com/content/www/us/en/architecture-and-technology/smart-response-technology.html

 

I don't see where it says that it doesn't support IRST, I see it does support it in the document you provided. Furthermore, why would Asus provide IRST drivers on their support page for g551jm if they didn't support it?

It's really the other way around. It doesn't support Intels Smart Response because of the RAID requirement, but it does support Intel Rapid Storage because it works in AHCI mode as well.

 

hi guys, sorry what i write now but i must because in last years i love rog laptops and i own one year old one 17 inch rog as desktop replacement and my brother one rog two year old 15 inch rog.

today i was on many stores in my country and new 15inch ROG laptop G551 is holy bad :/ plastic look, from left and right side is it same as multimedial line from asus :/ only ddr3 geforce 850m (this one is because in my country only in 850m ddr3 but i true that in world exist 860m but this is for me about nothing because to my country into this time asus import only this), one fan with one hole etc etc etc. Asus this is realy from your company 15inch gaming laptop for this year? ach lol but no this isn't gaming laptop and not true ROG

(yes exist G7x1 series, with two fans and better look than G551 but when I look on for example 750 and older so in my eyes are still better models from previous years and in style look too :/)

so I still wait on release Asus GX500 2015 this is only one nice gaming laptop what is good from design side and performance side for this year from Asus
Please Asus company not destroy this one good look gaming laptop with someone bad choice (for example as lenovo destroy his y50 with tn display and not ips, or not m.2 connector but only sata3,..) I hold both my thumbs

 

Be aware Intel use a lot of very closely named technologies round storage, the HM86 supports IRST (intel rapid storage technology) but that does not automatically include smart response technology. It leads to a lot of confusion.

 

IRST - Intel Rapid Storage Technology = AHCI / RAID (RAID is optional, varies by chipset model)
ISRT - Intel Smart Response Technology (optional).

 

Does anyone know when will Asus use the GTX960M in their next ROG G55x series ?

 

Yes, you were right about the caching, it appears that Smart Response is implemented within the Rapid Storage Technology GUI, if you have a RAID array. Otherwise, IRST apparently only enables NCQ (Native Command Queuing) though I'm not sure why they put the SSD in, when it's not required for NCQ.

Furthermore, I can't figure out what is the intended purpose of the 24GB mSATA SSD in G551JM. It can hardly be used to install the OS on it. It's only reasonable purpose would be caching, but how exactly it is to be set up if ISRT is not supported is not clear to me.

hiberfile.sys can't be moved from the Windows 8.1 root to the SSD, which would be the best bet. pagefile.sys and swapfile.sys can be moved, but they are not as essential to the fast boot as hiberfile.

I am yet to discover the purpose of the SSD that came with the laptop and the way to use it in the best possible (or at least inteded) way.

There is another caching software advertised on SanDisk site (manufacturer of the built in SSD), but it's only available to OEMs and not to individual users for download. It's called ExpressCache®,but it's not mentioned on Asus' support pages nor their download section.

P.S. I found the ExpressCache download on SanDisk's website, but apparently they say it only works with the 32GB SanDisk Readycache SSD. So, I guess, if it's not one thing it's the other

 

OK, I found a version of ExpressCache software on Asus support site for a different (older) laptop model. It lists only Windows 8 x64 as available OS, though I'm running Win 8.1.
Anyway, I installed it nevertheless and upon finishing it only prompted me to restart. After it restarted nothing happened, I couldn't tell if it was running at all, let alone running properly. The README file stated that the software is designed to run and configure itself without any hassle for the user. Checked Disk Management console, SSD appears unformatted. Checked Windows Services, and sure enough ExpressCache service is running. But how to tell if it's actually doing anything useful? Found the shell command on the Internet, from the users of other laptops having the same issues. Here's the output.

So it appears to have cofigured itself to use that SSD after all, but I guess I'll have to wait and see if there are any performance improvements, not that I would notice anyway since I got this laptop only yesterday. But at least I've made some progress to put that SSD to it's intended use.

 

As you found Asus have their own software/firmware to manage it, looks good to me and will likely be doing its job.

Boot times should be a little faster etc.

 

You can run CrystalDiskMark to verify performance changes.
http://crystalmark.info/software/CrystalDiskMark/index-e.html

 

Unfortunately I did not run any benchmarks prior to installing ExpressCache, so I don't have anything to compare it with. I did find the reviews of the software though, around the Internet, and they all say that the impact is significant in the positive sense.

I can say that the laptop is very responsive, wakes up from sleep instantly, haven't noticed the HDD being the obvious bottleneck etc. Haven't done cold boots to verify or measure the time it takes to get to desktop, but those few times I did restart due to setup requests, it was fairly quick.

This is my testing phase though, I only installed Windows 8.1 Enterprise Preview free from the MSFT site, to see how it runs, since I've not used Windows 8.x before as my primary OS, and I did not buy a genuine copy of Windows yet, since I want to wait for the release of Windows 10 if I'm gonna shellout €150+ for a legit Windows copy (I'm not big on major versions OS upgrades, I'd rather do a clean installation of a new major OS version).

I will test the speeds when I do the final (re)installation one of these days.

 

That's good, if you find any performance boost then please share with everyone, thanks and enjoy!

 

Benchmarks don't usually work too well with caching solutions and they can mess with it a bit since it can load junk data into its store.

 

I can confirm this percent often put my G551 in to sleep mode and he wake up instantly, and he is immediately ready for gaming

 

Can someone know how to make g551 working on batery like on DC i want full power on battery like on DC is there are some programs or in windows some settings to make this posibile?
Thanks you all

 

It's written into the firmware to stop the battery melting.

 

It cannot be done, unless you get a big battery that is about the same size of your notebook, and heavier.

 

Well something the size of the one in the 6.5kg sager machine would do, the one that has to be screwed in lol.

 

Ooh let me see, it probably weighs 1-2kgs? That's one big battery
