M570TU: Is it meant to be this bad, or is something broken?

another hour into it with everything on full load and... nothing

green bars thruout


this is a first thats for sure


$#%&*#*^&%$&#(*^$&$% intel wifi

 

eagerly waiting for a new bios/ec in case its a clevo problem and not intel.

tested it last night for 3-4 hours and not a single spike with the wifi drivers disabled.

 

Hard to say if it's the wifi. If you happen to change it and the problem goes away... let us know.

 

well thats what i did last night without a single spike

re-enabled tonight and having tons of them

 

What I am saying, is that it may not necessarily be the Wifi, but the way the wifi interacts with other components of your PC, it could just as well be the MB. You just have to change the Wifi and see, maybe you can swap it with one of your friends that have a similar one.

 

just to update this, i ran an in depth dpc latency check and found out that the file causing the spikes is dxgkrnl.sys

it all points to the gpu now.. this sucks.

does anyone know if sager can accept an rma of only the gpu and not the entire notebook

thanks

 

How did you do the analysis? what program.
isn't dxgkrnl.sys part of directx ?

 

with some sort of developer tool. its called windows performance toolkit.

you'll find more info on it under xperf

really nice tool


then again i got pi$sed off and just went ahead and pulled the wifi card out and ive been spikeless for a while now.

this is taking a pi$s

I think its easier if you can just upload xperf and xperfview somewhere. To install this thing it wants me to download Win7 SDK which takes at least 500 MB ?!?!

I am just curios if it's the same thing in my laptop.

Hahaha! dxgkrnl.sys is the directx kernel. So it's a directx problem... strange.

Are you using a 5k series intel wifi card? I had heard those wifi cards were pretty buggy for a while now. Thats why almost a year ago now when I built my 1651 I purchased a 4965AGN card instead of the 5k series.

 

That actually gives me a good idea . Thanx

 

nah 500mb is bull. the windows performance toolkit is part of the sdk.

after you download and install the sdk, go to start/programfiles, find the sdk, go under tools and you'll find a shortcut for the toolkit and install it.

sooo... any suggestions as to which wifi card i should try? must be N since G sucks for me right now

 

intel 4965AGN or a atheros wifi card.

 

ordering an atheros on monday then. is the latest model the ar5008?

 

Atheros AR5BXB72 is probably what you are looking for check on ebay. I would actually recommend the intel 4965AGN some people have had problems with the Atheros AR5BXB72 due to heating, but it was hands down the best wifi I have ever used back when I had a lenovo T61p.

 

AR5BXB72 it is then. its not nearly as cramped in the 5797 as it is in other laptops.

is it just heat and battery performance or could it fail/malfunction/blow up because of it.

last thing, is it compatible with the clevos? some manufacturers blacklist non stock wifi brands from the bios.

edit: after a quick search, it seems to be what mac is using in their macbooks and lenovo in the t6x series. you sure its going to work?

 

no reason it would be blacklisted. If your worried about it not working I would just get a intel 4965AGN.

 

Did you manage to change the Wifi? Has that solved the issue?

 

when i pulled the wifi completely the small red spikes you were having aswell are gone, but not the big ones. i still get those, granted less frequently but they're still there.

having some paypal issues so cant try the atheros just yet, maybe next week.

anyone want to lend me a 280m to try lol. i emailed sager asking if i can rma just the gpu but not gotten a reply

 

Oh, I see, you only have an issue with the small ones.... well those are no issue to me. All green . Also changing the power preference to performance makes the regular smaller spikes get well... smaller.

I thought you managed to solve the big ones, those are the ones pissing me off and have been around for about 1 month. I think they've started with one of the Windows 7 critical updates back in early October.

I doubt Sager will give you an RMA on your GPU just for that, although they should.

 

well no i dont only have an issue with the small ones, because they dont cause any system instability

the big ones however, apart from crackling they sometimes freeze the laptop aswell.
