M4700 Owners Thread

Assume so, i7 extreme will cook under single pipe heatsink. Read somehwere in this, or M6700 thread, mention of 55W dual pipe CPU heatsink. Not sure if there's a dual pipe GPU heatsink, which is what I'm really looking for.

p.s. that is a truly awesome cat you have there:thumbsup:

 

The M6700 only has two GPU heatsinks, one for nVidia and one for AMD as far as I know and both seem to be triple heatpipe. It is very likely that the M4700 has an AMD and a nVidia heatsink, but that they also both have the same amount of heatpipes.

 

No wonder M6700 owners are claiming low-GPU temps, triple pipe heatsinks! lots of space clearly, not even sure if a dual pipe will fit in GPU area on M4700.

 

I should get my M4700 this week or next. I had to push hard with IT department to get the nVidia card rather than default AMD one. I wanted optimus for reduced heat / quieter operation / better battery. Did I make the wrong decision?

which runs cooler - the AMD or nVidia graphics?

 

You can see the pictures in Bokeh's M6700 owner's review, you got two pipes going to the GPU fan and one going to the CPU fan, if I had to take a guess, I would say dual heatpipe for the M4700.

 

Hi guys,

I've installed 16gb of ram (1600Mhz Corsair Venegance) in addition to factory 2gb of ram (also 1600Mhz). Everything works fine, all 18gb are visible in BIOS and Windows, but it runs at 1333Mhz. Can anyone tell me why and how I can fix it? I was going to remove the factory 2gigs of ram to check if it solves the problem, but decided to ask first

Thanks!

 

If the memory specs aren't identical then you can get stuck with a lower speed. Removing the 2GB will likely fix it. Even if the speed is the same (1600 MHz), mixing other factors (i.e. CL rating) can cause the speed to drop to a lower level.

 

Bokeh's review is excellent, but I do not see any under the hood pics that would indicate single, dual, or triple piped heatsinks.

When the I did the repaste on my M4700 a couple of weeks ago, I believe CPU and GPU heatsinks were single pipe. Another M4700 user got their hands on a 55W dual pipe heatsink for the CPU so I assume the single pipe is the OEM default.

Pretty incredible that the K5000M can run under 40c during light load conditions, all the while driving 4 monitors. I'm high 40s under light load with just a single monitor connected -- would love to get into low 40s on CPU/GPU, but might not be possible with single pipe heat sinks.

They're in the "Spoilers" section at the bottom, you have to click to see them in the post.

The GPU has two heat pipes going to the GPU fan and another one going to the CPU fan. I believe all M6700 are set up this way. I wouldn't be surprised if the M4700 is similar (maybe just two heat pipes?) but I don't think I've seen any detailed shots of the insides of the M4600/M4700 so I can't say.

 

Hmmm, M4700 GPU definitely has a smaller footprint (i.e. no 3rd pipe), but now I'm on the fence, maybe it is a dual pipe setup afterall -- just can't remember, was a rush thermal repaste job, 1 day before leaving the States, wasn't paying attention.

I'll dig around and see if I can find some evidence one way or the other.

Thanks for the pics.
