M17x and DPC Latency - Page 2

Wow ... direct access (dual) and not running around with multiple roads (quad) probably makes more sense?

cheers ...

I went threw the motherboard and had a feeling it was a power noise isshue as it seemed to stay at certain patterns from the diffrent places I frequent, and low and behold, im not an electronics major, but it appears that a power brick mod , cable shielding and Sheet shielding, the latency would subside, it seemed to subside when i used shielded cables/sheets over the graphics cards and wireess card. also, takeing note how the power section on the motherboard is so danm close to the bus, its a wonder why other anomolies have not been happening.






From what i have gathered, that the wireless card was a beginning culprit in the isshue, as i moved on past the power noise bit, I noticed that if I were to underclock or even tinker with the bios on the geforce cards, and lower the amount of voltage going in by chaging some resistors on the board, (yes a heat gun is a wonderful ****ing tool) and some other nifty over complex mods, the latency was resolved without the use of shielding sheets inside my machine... But for those out their, I wont divulge on how to repair this, i have done the mod to 2 machines already, (and so alienware or dell or what not doesnt try to slap a lawsuit on me for reverse enginnering their tech, ) now those that feel confident and know what im talking about, it works. Ohh, and turn down the fans and the latency goes down as well but we don't like overheting.. at your own risk people.

im under edgucated and fixed this, you guys need to hire better people

well there maybe more to this saga

There is talk that Dell has determined this is a desgin flaw with the NVIDIA chipset, and a replacement with a Intel Mobo maybe the only fix.

Not sure if this is true as ther eis no official statement by Dell, but one wonders it they would simply replace them with the refresehd M17x.

All I do know is the A03 BIOS did not fix the issues

So now nVidia is back into the spotlight again? They need to roll out new products instead of re-badging things.

cheers ...

Time to boycott nVidia and stop using the crap they keep dishing out. My next two system are nVidia free. yeah!

no, a system i modded had an ati, was actually worse, what the culprit is i suspect is the mobo, it needs a redesign and/or proper shielding, in some case'es, a power brick coupled with using custom flashes and voltage values fixed the isshue.

this is what it is, it was only a matter of time till u cram so much together, that you wuld get Interference from a power source, , imagine putting a power brick next to a processor and watching the clock cycle on an o-scope and see the noise,thats what is going on here from the machines i see.

bottom line, it (the board, not nividia surprisingly) either needs a redesign, drasticly reduce the voltage to the video cards, kill the stepping on the processors by manuelly modding them or firm modding them , or shielding sheets, or a combinaton...

i do not have a degree in this, but i can , like anyone if they were taught , use eagle cad, draft up this multi layered board if they would give me the .brd and .sch files and component librabries, and show u were the problem is, again if i do that , i face possible legal isshues...

bottom line is, its a flawed design, but think god, alienware's call center is based in costa rica, no india, and at least they actually try to help you, and when a fix does come out ( I noticed MR *Public Relations* Dell man said call tech support if the bios revision doesnt work)...

you should also see the 24 gig ram, i7 water cooled overclocked system they have at their call center in their small as gameing room, it's...pretty bad ass..

ohh, and completley off topic,

can someone please Post a link for that respawn dvd for an m17x? My cd is cracked and dell is feeding me bs about Me not gettting one, or pm me please? much thanks

OK sorry I am slow on this. This is Nvidia chipset? Not say on notebooks with Intel chipset and Nvidia GPU? I need to know.

I think it has to do with the Intel / NVIDIA combination including the onboard GPU (9400) with this chipset.

the refreshed M17x-R2 has an intel Motherboard with no NVIDIA Chips or GPU and has no issues what so ever.

Also this issue is not just with the M17x, but seems to be with manyof the NVIDIA chipsets used by other computer makers

It's quite probably the chipset. Since these GPU's are used on other chipsets without these issues, it's pretty easy to narrow it down to that.

What remains to see is if a well written BIOS can cure it. But you can bet until the jury comes in on that one, there is probably a reason (removing the possibility of comparison) that the I7 model comes only with AMD GPU's.

that is why i never liked nvidia motherboards.. everytime dell uses a nvidia motherboard whether it be a desktop or notebook there is nothing but problems.. that is why i always been a fan of intel mobos.. they work great with nvidia or ati gpu's.. when dell went to the nvidia mobos in the xps desktops starting with the xps 600 there was noting but problems.. the gen2,3,4 and 5 were all good machines. this is why i was hesitant to buy the M17x but i pulled the plug anyway.. i hope dell?alienware stay away from nvidia mobos. or should i say chipsets..

well Intel is basically divorced from NVIDIA now, for how long who knows.

i can see why...

And I think that's why there isn't SLI on the I7 machines... Nvidia's "fine be that way" response.

But sadly the 4870/5870 performs so well that this is another "poor decision" by Nvidia.

Anyway, the 5870's are going to change the game for sure. With I7, this notebook will do very well

make one wonder if Dell would even bother with NVIDIA including the upcomming DX11 GPU

OK guys it is the chipset? It is the switching from say the primary to secondary GPU? So this does not include a Nvidia card that for example switches to Intel IGP? Which would indicate an Intel chipset and that would mean using Intel's switching method?

Just to make clear I am not asking for this AlienWare model. I want more of a general answer. For XoticPC forum post.

Yep. I would say "it is the chipset".

cheers ...

The fact that it doesn't happen on ATI cards would suggest it's something with nvidia. I can't believe this problem hasn't been fixed yet.
