msi 1651 owner's: help!

hey guys! i hav a big favor to ask, if anyone has a few spare moments. im interested in one of these laptops for doing some audio work but with laptops many times its hard to tell how well they'll work with audio before you actually have it.

im trying to figure out the dpc latency of the system because that can be a good indicator of potential problems. if anyone would be willing to run a 'dpc latency checking' tool on their 1651 and let me know the result, id really really really appreciate it!

here is a link where you can download the program: http://www.thesycon.de/dpclat/dpclat.exe (310kb)

if it doesnt give good results off the bat, sometimes disabling certain components in device manager can help. itd really help me out if i can get this info before ordering this laptop. so thank you if you'd be willing to help me out!!

 

anyone willing to help me out?

i edited the post with a link to the little program you can use to check the latency.. (more info on the program here: http://www.thesycon.de/deu/latency_check.shtml)

ive used it on other systems before, its really simple!

thanks,

Hi! I've registered because I saw nobody was helping you. I have an MSI GX620, and as far as I know its identical to the 1651.

After starting the program, I started getting values <500µs, but after about every 7 seconds i got a value between 1000µs and 2000µs. After some time I got this message:

"Some device drivers on this machine behave bad and will probably cause drop-outs in real-time audio and/or video streams. To isolate the misbehaving driver use Device Manager and disable/re-enable various devices, one at a time. Try network and W-LAN adapters, modems, internal sound devices, USB host controllers, etc."

Shall I start disabling devices and see what happens, or is this result good enough for you?

(I'm using Windows Vista Home Premium 64bit)

 

hi tpmportal! thanks so much for helping me out, i really appreciate it.

hmm... those spikes are a problem but i bet its a networking device thats causing them. if you wouldnt mind could you try disabling a few devices to see if it gets any better? id start off with the networking devices (wireless/lan/modems/etc).. they'd be disabled anyways. if that doesnt help you might also try disabling bluetooth, firewire, the built in soundcard, etc.

again thanks so much for the help. ive done a lot of looking at the 1651 and if i can get a good result with the latency i think ill be sold on it!!

Nothing has changed so far, I disabled all the network devices, bluetooth, soundcards. I'll now try installing the latest drivers, as I have the ones installed that were on the cd included. I'll report back when I'm done.

Update: After installing the new drivers spikes became less frequent, and they dont reach the red area, but they are still present. Another thing is if I use the turbo/eco buttons or adjust the brightness or volume I get some really high values, but after that it goes back to normal. Typing also increases the frequency and the height of the spikes.
I think more tests are needed on other 1651-s to see if its a general problem, or only mine has it.

 

I got a spike to 2187 u/S once, and occasional spikes in the 1000-1100 area.

EDIT: Second run without the LAN/Modem/Wireless on: Highest spike was 1102 u/S, which occurs once every 10 or so bars. Otherwise, it hovers around the 90-110 range.

 

hey guys thanks so much for taking the time to help me out. to make sure im understanding you right, most of the time its around 100u/s but there are consistent spikes that occur every so often in the 1000u/s range?

unfortunately unless something changes its not looking too good for this laptop at this point for doing audio stuff.. i was all excited for it too. :/

i wonder if the 1722 is the same way, that was another model i was considering. any 1722 owners feel like giving this a go??

thanks again guys!!

 

Yep. I forgot to turn off the networking devices for the first run, so at least that 2000 one is gone.

 

This looks like an extremely inaccurate testing method, you have the variables of different specs on hard drives, ram, and processor speed/fsb/cache which will be different with everyone's laptop since these laptops do not ship with these components. All of these components will affect performance.

 

thats a good point but from what i understand, the dpc latency of the system has less to do with overall system performance and more of measuring how well the system deals and manages the devices plugged into it(sort of like a motherboard/system architecture test). i could be wrong, but i dont think a different cpu or hard drive will really change the dpc latency too much.

i really wanted one of these msi systems to work bend of discouraging... ahhh why is a clevo m570 barebones system cause they're so much more affordable than the sagers/clevos but this is kind of discouraging... ahhh why is a clevo m570 barebones system $1500??? :/

 

Just curious, what audio hardware/software are you planning on running with it?

 

ah sorry havent been on in awhile.

my audio software is Sonar 7 and i run a few different interfaces... im actually in the middle of an upgrade right now and have not decided on what my new interface will be!

 

Hey Photores

Still on the thread?

I´m the happy owner of a GX720 (same as 1722 - ID2 I think). I use it in my studio for recording and composing, mainly in Nuendo 2 with lots of DXinstruments and different FW interfaces.

Had the same problem with latency as described by others here, the solution is to install XP and disable LAN and battery - now my DPC Latency readings are great: 19-30 ca. with occasional spikes of 100: No more clicks and pops in sound Never got it working in Vista Testing in WIN 7 now.....

Generally very pleased with the beast. Its fast, low noise emmision and built in Firewire is ok with audiointerfaces.
