**OFFICIAL W860CU/NP8690 Owners Lounge**

I have a premonition...a crazy one probably

Eyefinity build on W860CU. Anyone tried playing on 2+ monitors?

 

Tried with a 180W PSU, but the problem is still the same: sudden shutdown after a few seconds of wPrime.

I am using the .12 BIOS for the XMG7C too, that has advanced options, and it works fine.

However, I'm still using the W860CU EC/KBC - this is what I'd like to change to see if that could help (W870CU users seems to be able to achieve higher overclocking with the 940XM).

 

Got it from this website:
power supply / AC adapter for Alienware Area-51 M9750: battery, power supply, display, etc - Laptop Repair Shop

The 940XM is an ES model.

 

a few guys here had problems with the 920xm es throttling at 80*c with occt.
your situation seems to be a lil different since they never reported getting a bsod.
where did you get your 940xm es?

 

I would actually be happy with a BSOD. It does in fact happen when I increase the single-core turbo boost at x31 or more. That situation is clear: I'm reaching the limits of the CPU and only VID increase could possibly help here (but there's no such option for the W860CU yet).

The problem I have is a sudden laptop shutdown (no BSOD, more like "pulling the plug") when all cores are loaded at x21 Turbo boost or more, well before the temperatures reach any high levels. This is why I'm thinking "power limits" imposed by the Motherboard/BIOS here.

The 940XM ES came from an official reseller, but I'm currently trying to get it swapped for a "normal" one, although I'm not sure this problem is linked to the CPU itself.

 

to see if it is not a psu limitation try to minimize the power of everything else you can
screen, usb, gpu etc and try again
if it is a cpu problem have you checked the thermal paste?
are you sure the cpu temp you read from the software is correct?

 

I have tried with pretty much everything turned off, and a GPU clock set to 200/300 (ATI 5870M): same results.

As for the thermal paste, it looks fine too:
x20 on all cores / wPrime 1024 -> T ~ 82°C: OK
x21 on all cores / wPrime 1024 -> T ~ 70°C : SHUTDOWN (no BSOD)

 

the gpu downclock doesn't change anything undervolt only
anyway it doesn't seems to be the psu

 

he never did mention having a bsod. he's having a shutdown problem which is different from a bsod.

my guess is that you really are reaching power limits. is this happening when you keep everything at stock?

 

Nope, no problem at stock. I'm also really thinking it's all about power limits. But I have read on this forum that MX15 / W870CU owners have reached higher frequencies with the same processor.

Since W860CU and W870CU share the same design/hardware, that brings us back to my initial question: since the BIOS EC is supposed to manage low-level parameters such as voltage, fans, etc. has anyone successfully (or unsuccessfully) flashed the W860CU EC/KBC with the W870CU one ?

Thanks-

 

Not that I know of. And I'm wondering, how is the EC/KBC connected with overclocking?

 

Hi!

Yes, I checked my temps. GPU is around 40°C and CPU is around 50°C. Thinks this is okay.
There is no beep at startup.
And what is ment with "reseating your RAM"? Just take it out and in again?
It appears to me, that it happens "a short time" after returning from hibernate. And then after it shut off and i rebooted it, it doesn't shut off again until the next wake up after hibernating.
Could this be related to OS? And no hardware thing?

Best regards!

 

i was also thinking power limits at first but as you said other have reached higher thresholds.
you could pm chinoobonic as he has the record for the highest cpu clock for the 8690 and find out what bios combination he uses.
also is there a way for you to test the integrity of that psu?

 

Yes, reseating is taking out the RAM and then putting it back in. This technique has worked for me on other laptops with a similar issue to yours.

 

yep I have flashed it and it works just fine

 

Interesting! Can you please confirm it's the EC/KBC (firmware) that you flashed, and not just the BIOS ?

What is the maximum multiplier that you were able to set with 4 cores ? (assuming you have an XM CPU and Throttlestop)

Thanks-

 

I think you guessed right
here is what I have
bios revision 1.00.12GH
KBC/EC firmware 1.00.10
And I have only a dual core anyway

 

Have you tried your standard 120W adapter since this issue arose? The 120W adapter will support multipliers well above the problem area.

 

Yes, I was able to try with two 120W PSUs as well as the 180W one: same results.

But I also came up on this post:
http://forum.notebookreview.com/sag...levo-w880cu-owners-lounge-24.html#post6760849

It looks like I'm not the only one with this problem on a Clevo. I can reach slightly higher multipliers (x20 x24 x28 x29), but it is probably because I disabled Hyperthreading.

Maybe it's just the way it is with Clevos.

 

I wonder if silent mode ("M" button) will ever get fixed via any updates. It is louder on than it is off.

Better yet, I'd love to be able to change the fan speed to dip below 46/47%! Sometimes I find my laptop's fans overwhelming in a small quiet classroom. Nobody seems to notice or care, but it still bugs me.

 

But see: http://forum.notebookreview.com/6763378-post247.html. All is not lost for W8xxCU's.

 

You can edit the fan settings in the vbios.

 

Has anyone personally done this? If so, what type of settings work for you?

I'm going to sniff the forums on how to actually get into the vbios as I have never done it before.

 

This is the Fan Settings screen of the 5870m vbios.



The "Duty cycle min (%)" is the minimum fan speed, regardless of temps. This is the source of the 30% you often see on various system utilities. You can raise it or lower it, depending upon your purpose.

The "T min (*C)" is the temp at which the fan begins to increase output to combat rising temps. The default is 45*C. Under standard settings, the fan increases output (over 30%) by 1% for each 1*C in excess of T min (45*C). If you want quieter fans, increase this setting to delay higher fan speeds, but expect higher temps..

The "T max (*C) is the temp where the fan speed hits 100%. You can change it as you wish.

The "T slope (%)" is a derived calculation reflecting the foregoing settings and the rate of change resulting therefrom.

With those settings, you can make the video card fan act however you wish. Just change the settings, save the modified vbios file and reflash the video card.

 

aw man now you guys have tempt me more to get 940xm es and new 180w psu to replace my 120w XD

 

I switch settings and flashed the bios, but nothing changed.

In GPU-Z the percentage value of the fan speed is shown correctly, but the actual speed (noise level) is not changing. I tried idle values of 1% and 99%, no change of noise or activity of any kind.

By the way, the fan speed is only shown in percent, no real values are shown (--RPM).

Is there a trick to make the changes applied?

P.S. Sorry for my bad english, I am german.

 

I have the opposite concern; I want increased fan output to offset relatively high temps with the 5870m. I left the minimum duty cycle at 30%, reduced T Min to 40*C and T Max to 100*C. Now, at 50*C (net), the fan runs at 40% (instead of 35% per stock setting), presumably contributing to reduced operating temperatures. I am relying upon the % fan speed values reported by GPU-Z, Everest Ultimate, HWiNFO32, etc.; I do not have a system utility that provides reliable fan RPM data. Perhaps I am getting only a placebo effect and the whole % fan speed reporting is some kind of scam by the utility publishers, but it "feels" (LOL) like it works, although given my relatively modest modifications, the changes are not dramatic.

 

I haven't had a chance to mess with this myself, it may yet be a few days. This is pretty interesting information though. I wonder what the deal is regarding that fan noise, even at 1%?

 

Hi Guys

I'm trying to find a opticial HD caddy for my 860. Reading through the threads I can't find which one to buy - has anyone here got one installed? If so could you let me know which one you bought?

Thanks guys

 

guys any of you tried using the machine with dual external lcd? such as in eyefinity mode via the hdmi and dvi port.

 

I have one installed with no problems but note the warnings about poor packaging. I recommend you take note of the specifications and get one elsewhere from a different seller. The only issue is you won't be able to guarantee being able to use your original facia on the new one but you can with the one I linked to. Also some one else received a non working one probably due to the poor packaging so be warned.

 

Hey guys I just plugged in my laptop to my router using an ethernet cable and noticed that there is no lan driver installed. I went into device manager and noticed that only the wireless card driver has been installed. Tried to install the NIC lan driver from the CD but it says device not found.

 

Still waiting on the GTX 470M. Still no news yet on retailers getting the card. I'm expecting it to be around $450.

Edit: Just got a reply from RJTech: "It should be available in the end of this month or early next month. No pricing info yet."

I'm using the sager .16 bios currently with a Asus 150w PSU. Highest overclock I got was 3.7 before it shut down. That's the limit I get with the PSU but i run stock at the moment. The reason it shuts down is not because of the bios, but not enough power from the PSU. I couldn't get past 3.3 on all cores with my 120W psu.

 

Ethernet cable has to be plugged it while installing the drivers.

 

Off subject but does anybody know the stock clocks for the nvidia 285m? I have the 280m but fear going over 1000 memory clock speed b/c I read somewhere that the memory is not rated higher than 1000 for the 280 MXM 3.0b? THX!!

 

dont go above 1000 for memory.
keep the shader:core clock at a ratio of 2.5
slowly keep increase your core/shader and memory.
i use a max of 620/1550/985 without bios voltage adjust.

 

I usually use 650/1625/1000 on the stock voltage...but after looking at others and what they have done, I keep on seeing memory at 1050 or sometimes higher...1100ish.

Good to know! I would rather keep my card for a long time than get slightly better FPS and have it die in a year or less.

 

Stock clocks are GPU Clock 600, Memory 1000 and Shader 1500. I have never bothered to overclock and have had good performance in all games including the recent Lost Planet 2 benchmark. I am still looking to installing the GTX 470M when it arrives though.

 

I'm all over the gtx 470m too! Better start saving now though....

 

any idea they said when gtx 470m releasing?

 

guys, im a 820qm user, if im going to upgrade to 940xm, will i feel lots of difference?

i will be using my machine primarily for compressing and decompressing videos,editing and music editing also.

 

Reasonable amount. At stock settings, for apps/tasks that utilize 3-4 cores, the 940 runs at 2.40GHz vs 2.00 for the 820, i.e., 20% faster, but the 940 can be overclocked easily to run at 3.00+/- or more on all 4 cores for a 50%+ speed increase for your primary uses, at a cost of increased heat and power usage.

 

i have my gtx 260m overclocked at 670 1650 990(not all time) with 1.03 voltage to be more stable.it runs like dream..i want gtx 470m too!!

 

somebody quoted a while back that RJtech said that it should be released end of Oct or early Nov. People are speculating that it will cost around the mid $400 or so....but who knows....

 

Good evening,

I'm still struggeling with my gpu fan. I found a nice dsdt editor ( DSDT editor and patcher - InsanelyMac Forum ) and extracted my dsdt file. but what should I do with it now? Which value should I edit to set the fan speed in idle to 0 RPM?

Thanks for your help.

 

revelator - you seems to be very expert in oc ing the extreme processor, is it ok once i get my 940xm, could you guide me to oc it?

also another question, when you said 3 ghz and above speed, it is on all 4 core 8 threads or just 1 core 2 threads?

i don't mind the heat and power consumption as i will be using the machine on air con room and near the electricity plug all day

 

Hello again,

I'm still trying to keep my fan quite in idle mode, but by surfing through the internet I found a vBIOS for my ATI 5870m that allows Powerplay and Overdrive. The Bios is from a MSI card. Powerplay works (testet with "FurMark" and "GPU-Z") Overdrive works too, but the RAM-clock is not set to low value in idle, it stays high and the fan control does not work. The CORE-clock is handled correctly. I disabled overdrive and used the Redeon Bios Editor 1.25 to set my normal clock to my prefered oc settings. I had flash my card using an usb-stick for the first try. After the new BIOS was applied I could use RBE to change settings (forced flash due to check sum error).

You can find the bios here:

Sorry, the description is in german, but the file "newbios.rom" works for me.

P.S. Do not take any responsibility if something goes wrong / breakes or does not work. I just wanted to let you know.

P.P.S. Sorry for my English, I'm still german ;-)

 

The utility ThrottleStop makes o/c experts of us all with extreme processors. I will be happy to answer any questions you have.

Using T-Stop, you can easily overclock the 920XM/940XM so that all 4 cores/8 threads are operating at 24x (3.20Ghz) or 25x (3.33). You can go higher, but heat becomes an increasing issue for sustained use. The key is power. T-Stop allows you to not only increase the multipliers, but also to increase the TDP to levels necessary to provide the CPU with the power it needs to operate at the higher speeds, but also allows the CPU to draw more power than the motherboard/powerboard is designed to handle. It's a delicate balance at the fringes. It requires about 82 Watts for the 920XM to operate all cores/threads at 24x (3.20); I assume it is the same for the 940. It takes about 91-92W for 26x (3.47) and usually requires a bigger PSU (150-180W). Above that is danger zone for the W8xxCU's; some can, some can't. I now stop at 25x for my own uses, but some push 27x with no adverse effects, but you can fry things at the upper range. So be careful and watch temps closely.

 

wow 3 ghz for all the 4 core 8 threads, that will be like 1 ghz improvement from the 820qm im using now, definitely making me drool just by thinking of it. ok, on monday i will start ordering the 180w psu and the 940xm

the keypoints here will the psu and the temp where they will be going at when at full load right?

btw can, the 820qm be overclocked above 1.7ghz for 4core 8threads with this program you said?

 

You don't need to be in a hurry to get the larger PSU; in fact, it's probably smarter to stay with the stock 120W unit until you get the hang of things. The stock PSU will let you do 24x (3.20)-25x (3.33). Save the extreme stuff for later. Remember, remember, remember, too much power can kill your motherboard. These Clevos cannot handle the power loads some other gaming notebooks can, so caution is crucial.

The 820QM cannot be o/c'ed with T-Stop; both the multipliers and TDP/TDC are locked on the non-extreme processors (with rare and occasional exceptions).
