1761 differences

Hello. This is my first time to post here. However, I have been researching for a while to collect a lot of information particularly from this forum. I am wondering if the motherboard is different between GTX 570M model and 580M model of 1761 barebones. I guess I am particularly concerned about the GPU voltage capability. I understand that BIOS control that. However, I am sure there is a system limitation how high it can go. I guess I am planning to mod it with 7970M some point. So I would like to find out if either mobo is capable of providing enough voltage for overclocking it.
I appreciate any information. Thanks.

 

I have been concerned about this myself. I am using the older 1761 (570m) and hope on upgrading to faster cards when they are readily available on ebay. I have heard that the newer ones have something reworked so the mxm slot can provide more power for the 580m.

I did some quick research on notebookcheck reviews and pulled up these total power consumption numbers at load:

MSI GT780DX (1761 older) w/ i7 2670, 570m 3gb = 125W to 167W (peak)
MSI GT780R (1761 oldest) w/ i7 2630, 560m 1.5gb = 124W to 195W (peak)
MSI GT70 (1762) w/ i7 3610m, 670m 3gb = 122W to 218W (peak)

Clevo P170EM w/ i7 3720, 680m 4gb = 106W to 183W (peak)
Clevo P170EM w/ i7 3720, 7970m 2gb = 120W to 200W (peak)
Clevo P170EM w/ i7 2670, 675m 2gb = 124W to 218W (peak)


Their results look inconsistent with the MSI notebooks. But the 580m / 675m clearly draws 25 to 50 more watts over the 570 / 670m at larger loads. The 680m consumes significantly less power than a 580m or 7970m. Barring any mxm bios locking, which I believe MSI hasn't done in the past, I think the 680m would work fine in a older 1761 barebone. The 7970m might work too.

 

Thank you for the information. 16F2 seems to have different power capabilities since PSU was different based on which GPU it came with. However, I noticed that 1761 always had 180W. Normally I would choose newest one which is 1762, but I am concerned about the Optimus for upgrading the GPU. I suppose I don't have to worry about it if I only use Nvidia GPUs.
Another thing is that I can find 1761-ID1 for $780 or so. If I were to go with 1762, I am going with 675M since the price difference from 670M model is only 70 or so ($970 from PROVANTAGE). I can save $200 if I go with 570M. I am not sure if 1762 is anymore capable to be upgraded than 1761. Either way, I won't be buying 680M for at least year or so. It is too expensive......
Let me know if you find anything more. Thanks.

 

This is little off topic, but MSI whitebook website has taken 1762 off from their product line. Does anybody know what is going on? It had it week ago.....

 

The MS-1761 with the 570M VGA and the MS-1761 with the 580M VGA use two different part number system boards due to the different power requirements of the VGA cards.

Typically as the VGA cards are revised/upgraded so are the part/revision numbers for the system boards. The later VGA cards are not usually compatible with the older boards, they may boot and run but not perform to their max potential due to the lack of available power. I have seen the two different boards called "reworks" but the actual part/revision number etched into the boards are different indicating they have not been "reworked".

 

Thank you, Rob.
