**OFFICIAL W860CU/NP8690 Owners Lounge**

hahaha thanks for the information, learned alot. cant wait for the 940xm to arrive

 

My personal experience with a W860CU is not that good. I have a 940XM also, but I am only able to achieve x20 on all cores (~2.6 GHz), anything higher and the laptop just shuts down. And that is with HT disabled, if I leave it turned on, then the maximum multiplier becomes x18 before the laptop just gives up.

I don't know if that's my system or if it's normal.

What really confuses me is that I can reach x29 x28 multipliers on 1 or 2 cores, and the power drain from the CPU is then much higher than 4 cores at x21, and yet the system is perfectly stable and doesn't shut down.

*boggle*

 

shuts down maybe due to power shortage?

 

That's what I thought initially, and therefore bought a Targus 180W PSU.

Unfortunately, this doesn't seem to help.

 

It won't shut down due to a power deficiency; it just won't be able to operate at the selected frequencies, sometimes called "power throttling." That's what happens now if you increase the multipliers, but leave TDP/TDC at stock settings of 55W/47A (920XM). Even if you set to 24x across the board, at full load, the processor will only operate at about 17.5x because it's not getting enough power to go higher.

 

hi guys have u checked clevos website ? it shows gtx 470m and usb 3.0 for w860cu chassis any idea when its coming?

 

Is your 940XM an ES by chance? Ordinarily, that shouldn't matter, but the very limited overclockability of all 4 cores of your processor and the shutdowns are so contrary to the general experience that it at least raises the possibility of a defective processor. Sure hope not.

 

so it shuts down due that it only operates max at 55w, while it supposed to run above 55w.

interesting, i cant wait to try this myself

im very happy with my w860cu, especially with the express card slot, it help me alot in may ways need to see how is the performance of the 470m gtx before deciding to get it .

revelator, does the es effect alot it oc ing part? should i get the original version instead? the price difference do kinda cost an arm and leg for a small piece, i prefer get the 980ex of the desktop for the pricing

 

It is a 940XM ES indeed. I'm trying to get it swapped for a retail one, but it looks like my supplier has a very limited number of non-ES processors.

When I get a new CPU, I'll let you know of the results.

thanks-

 

55W is just enough to allow x16 on 8 cores, it seems. According to HWiNFO32, the TDP actually rises to ~62W at times, without any overclocking.

The shutdown problems I get happen when setting the TDP/TDC to 80+/60+, which is the only way to reach higher multipliers.

 

Standard TDP for the 940XM is 62W, apparently in response to the 25-24-18-18 multiplier scheme on the 940. The 920 is limited to 55W.

 

revelator, i have 920xm and using XMG set it to +x4 OC, i can reach high up to 3.7ghz, higher than 940xm which has 3.33ghz??. is the cpu-z figure really reliable? so far stable and maximum temp i got was 75 C. guys is it bad playing an hour with that temp?? i don't want to fry my w860cu, since you are more knowledge and i am asking your expertise.. Thanks.

 

i can even reach high up to 3.715ghz @ 28x stable temp. so far better performance in gaming rather than stock clocks which only can up to 24x. OC'd +4x really increased 20% i guess or much better and no shutdown issues..

could some 1 have the screen shot of the oced processor and showing that all 8 threads are running at that speed?

 

what software do i use that will show all 8 threads clocks speed?..

 

good question, maybe prime 95? revelator, any recommendation?

 

hi guys , i'm looking forward to buying NP 8690 with 470m when it comes out . My question is : Is it worth buying 470m instead of 460m , it will cost 150$ more , i play many different kind of games : RTS Total wars , SC2 ,FPS FEAR 3 ...up coming games. I want something to be able run those games at High setting atleast, i may play at Ultra. In this case , is 460m enough?
I have noticed the following issue with power adapter i may face . I'm going to build a np8690 with i7 740q (45w), 470m(75w), 6gb RAM .The cpu and gpu alone already reach 120w , but manufacture Adapter for np8690 i heard only has 120w as its maximum. Am i wrong? so will this adapter be able to handle my machine?

 

you can always go get the oem of 180w psu if you find the 120w not enough.

 

ThrottleStop itself, operating in monitoring mode (default) is one of the best ways to see what the CPU is doing. The "FID" column shows the multiplier actually being used for each core/thread; CO% is the load or utilization per core/thread.

​

The current version of ThrottleStop is available here -- ThrottleStop.zip - [email protected].

 

nice pics!! so it did shows all the threads are moving at x24 3.2ghz

this pic is taken when you are using 920xm i believe?

btw revelator, how does i7 920xm @3.2ghz compared to i7 920 desktop @2.86ghz? will the mobile processor better?

 

Unless you have increased the TDP/TDC settings, you cannot actually use increased multipliers even though you have raised them. For example, even if you set a 920XM to 24-24-24-24, it can't operate at those levels because the 55W TDP only provides enough power to operate all 4 cores/8 threads at about 17.5x. To get 24x across the board (3.20Ghz) requires about 82W, so set TDP to 82W and TDC to 72A. To operate at still higher settings requires more power, but that brings with it more heat and greater risk, so stay at 82W max initially. That is screaming fast.

Edit: if you set multipliers to something like 28-27-17-17, and run a single or dual core app, then you should get all or most of the benefit of the increased settings because only a portion of the CPU requires significant power. Just set, run it and log the results in ThrottleStop. It wii show you exactly what's happening.

 

i have dl`ed the T-stop. using that program, when i have the 940xm, i will able to start oc`ing right?


lol i`m trying the T-stop on my su7300 processor laptop, i managed to make it move till 1906.7 mhz from the original 1300 mhz i want my 940xm !!!

 

Right. Have fun. Be careful.

 

revelator, what about that 24-24-24-24 option you are talking about? how to enable that? since in you pic, the set multiplier button is not ticked...

also how to set or change the tdp and the tdc part?

 

Right clicking on the main screen brings up this window. Turbo Power Limits = TDP/TDC. Turbo Ratio Limits = multipliers.

​

 

ty for the info!!!!

now all i need is the 940xm

btw 120w can handle the 940xm, 5870m and 2 hdd right? or do i need to get the 180w just in case?

 

The Revelator do you have a es 920xm or a retail one?

Since i might buy a 920xm es from ebay to upgrade my 720qm
(my laptop has not even shipped lol)

The other thing im afraid of is the throttling issue..

 

Mine is an OEM. Came with the 8760.

Edit: I have never experienced, and am not aware of, any throttling issue with the W8xxCU's.

 

The engineering samples had throttling issue's when they got 80 degrees, I " think" have read that here. altho im not totally sure now.

 

Must have been a bad batch. There are a bunch of ES 920/940's in use here and particularly in the Alienware forums with complete success. You occasionally see some "pre-final ES" or similar nomenclature for sale on eBay. Those should be avoided completely. Laptopmonkey and ShirleyFu seem to be the preferred suppliers.

 

pardon me, but what is this throttling about? how to know which 940xm es should i get or not to get?


im thinking to get from this seller, http://cgi.ebay.com.sg/New-Intel-Co...-8m-/250708294285?pt=CPUs&hash=item3a5f60fa8d , is this a pre final es?

what is the difference between, oem and retail?

 

There is no practical difference between retail and OEM processors; OEM's are just those that are sold installed in a new computer.

Do not buy chips advertised as "pre-final" ES. There is no such thing. An ES is an ES; a pre-final is still a development chip.

If you buy from the reputable suppliers, you'll be OK. Before buying, post a link to the one you're looking at. There are plenty of members that can advise you.

 

Ok,
Is the seller laptopmonkey trustworthy?
link

 

what about the link i pasted,
is it ok for that unit?

edit : o ok did not saw you reply at above

 

You guys might find this thread useful. http://forum.notebookreview.com/ali...ere-buy-upgrade-alienware-m15x-processor.html

 

Hmm seems shirley and laptopmonkey are both good, thanks for the link.

 

@revelator- sir thanks for the brilliant info. i'll try setting up TDP/TDC.

 

@revelator

- sir thanks for the brilliant info. i'll try setting up TDP/TDC.

 

i have a 280m (75w) and 720qm (45w) and 8 gig ram, psu is no problem.
i also o/c may gpu but have not overvolted it yet.

 

so do you think it's worth buying 470 over 460 with that price?
your psu is 120w?
i won't plan on oc-ing so how about it?
i'd also like to know the power consumption of your laptop
pls help me out those questions

 

i havent seen a review of a 470 or 460 yet so its hard to tell; but in notebookcheck the 460 shows lower benches than the 280/285m. it could be the dx11 replacement of the 260m
my psu is 120w
i dont have a kill a watt so i cant measure actual power consumption

 

If you don't plan to overclock your machine, and you don't run benchmarks like prime 95 and Pcmark vantage at the same time your 120W supply is absolutely fine for your use.

 

i dont we wont see 470m until Q1 of 2011 cause 460m just released it should last at least a quater i think when mobility radeon 6000 will be announced at ces then we will see some 470m laptops

 

Hello,
I have the Xxodd XNi860Cu laptop, with Core i3 350 processor, 2x4GB RAM and the nVidia 285GTX. I have Windows 7 Enterprise 64 bit installed (legit, school license from the school I work at).

When I first installed it, it was very unstable. The computer would hang randomly when using internet explorer, when gaming, when doing nothing at all, etc. I used memtest and it gave a lot of errors. So I removed one of the dimms and started testing again. 1 dimm was good, one had errors.
So I kept on using my laptop with 4gb ram and it worked a lot better! I think without once hanging (but I'm not sure anymore). The other dimm was returned and after a couple of days I got another one. Installed the other dimm and the hanging and rebooting was back! Ran memtest again. After a couple of hours of testing and retesting it had 6 runs without problems. Seems the ram is okay now.
Sometimes I boot my laptop and as soon it gets into Windows 7 it reboots. So it can't be too hot I guess. Maybe power consumption problems? But then again, what power problems when it's just booting?
After the first reboot I can get hours of playtime in Adobe Audition and Adobe Premiere Pro and Call Of Duty Modern Warfare 2. Then all of a sudden it hangs in CoD MW2 when loading the map in a online game. The screen goes black and nothing responds anymore. I have to hold the power button till the laptop goes out and reboot it. Sometimes it all well again for a couple of hours and sometimes it's just the beginning of the troubles. It starts hanging in Adobe Premiere, Adobe Audition and CoD and I have to reboot over and over again.
Last night I had uTorrent downloading a 720p mkv. Nothing more. And when I woke up this morning the screen was black again and the torrent was only at 65% when I rebooted the laptop.
Does anybody know what could be the problem? Powerconsumption? Bad bios? I have a desktop pc that also rebooted, but it was every hour precisely, and it was a bios problem. Bios updated and no reboots ever since. That was months ago.
PC wizard tells me I have the Clevo CO W860Cu motherboard.
I couldn't find a bios update for the Xxodd XNi860Cu (but maybe I'm just too dumb to find it) and googling for Clevo W860Cu bios doesn't help either. The Sager NP8690 seems to be the same notebook, but is it so much alike I can flash my Xxodd bios with the Sager bios? I found the .16s bios for the Sageer.
It's an ISO file of 6MB with nothing in it, so it seems when I open it with Winrar.
Just burn it to a disc and hope for the best?

 

Aaarrgg! Just tried to watch the downloaded 720p mkv and it froze up with a black screen twice on me after about 20 mins. So I'm giving up for now, just gonna watch the movie on another pc.
Can someone help me out here, please?

 

@dannybroos
have you checked yur temps when this hapens?

 

RJTech says they're expecting the 470M at the end of this month. I don't know where you got the information of the 470M being released at least for Q1 2011.

 

kev any word on price and whether it will be made available for the 8690?

 

no news on price but i think clevo's website shows that it is available for the 470m, i'm not 100% sure though.

 

My temps while playing the mkv are visible here:
Imageshack - screenshotcd.jpg

and after pressing the M button (Silent Mode) it's this:
Imageshack - screenshot2gk.jpg

Detail: Pressing the Silent Mode button makes my proc go to half speed, as you can see in the screenshots taken. But my laptop starts to make MORE noise, like the fans are really stressing it to keep it cool! Also: going into this not so silent mode doesn't help, it still freezes up.
