Dell Precision M6700 Owners Thread

Re this issue of RAM, I just ordered a kit of two sticks of Mushkin Enhanced Blackline 4GB DDR3 1600, @CAS 9, 1.5 v, Model 997066. This is to go into my new Covet (arriving in a week, hopefully), which has already 8 GB of RAM. My question is: does my new Mushkin RAM run a problem with compatibility with my M6700?? Is the CAS of 9 an issue with the default RAM that is already in the Covet?? Any other issues that might cause problems?

Does anyone know if you mix CAS 9 with another set of sticks with, say, CAS 11, will it cause BSOD or other problems?? If a CAS 9 stick runs with a CAS 11 stick will the slower 11 bring the faster 9 down to its speed?

 

I saw that in France last month, and now it seems to be the same in US. Does someone know why Dell play with this option ?
Is there a problem with the IPS panel ? Or only a temporary problem to produce them ?
My M6700 was changed in garantee and it was difficult for me to get the new one with the same IPS panel in France
Not sound good to me (if there is a reliability problem, or no successor ?), as i have this panel (and need it because i use this computer to work on picture).

 

Seems like there is some problem with tinges of color in the corners of the display, and so a lot of people have been returning their displays for repairs/replacements, and it must have gotten to be not cost-effective to keep the IPS. Don't know if it's an inherent issue with making an IPS in general -- seems hard to believe -- but more an issue of many imperfect panels being made and bought by Dell. Now they don't want to deal with the problem, so they have discontinued them. Hope a solution is found; IPS is the only way to go as far as I am concerned.

 

No one know the current status except dell, best hope is that they are getting new panel for 6800.

 

Wouldn't be surprised to see the M6800 in the "late summer" timeframe. This is 100% speculation on my part. We don't have any info on the release window.

If you mix modules with different CAS latency ratings, it will probably work fine but you will likely be locked in at a lower speed (DDR-1333). The computer will have to find the "greatest common factor" --- the best speed supported that works with both modules. Best to use modules with the same specs.

 

You're right. My first M6700 IPS was horrible on this point, The temperature color difference between bottom left (red) and bottom right (blue) was 950 Kelvin. It was an issue for me as i work on pictures, color and black an white... But this laptop failed, Dell replaced it and the new one is better, "only" 370 Kelvin difference.
By reading forums, i saw that this problem was already on M6600 so i was sure it was solved while buying my M6700...
The people who buy this panel (+ 700 euros in France !) do that because they need a good screen. So if it is not the case, i can understand that they ask Dell a better one... Except this problem, this panel is very good for a laptop screen.
It is an LG panel (LP173WF3, LGD0310), so i hope LG is working to create a new version without this problem.
If the future Precision Laptops don't have IPS panel, i wont buy them.

 

I believe the stock RAM coming on my Covet will be DDR-1600 speed. Of course, my new Mushkin kit is also DDR-1600, so there should not be drop-down to DDR-1333, should there??

The invoice Dell sent me says:
8.0GB, DDR3-1600 SDRAM, 2 DIMM, Dell Mobile Precision MX700

Where can I find the specs on the default modules used in the Covet as purchased straight from Dell?? I mean, different CAS latencies shouldn't knock the speed down to 1333 should it??

 

Different CAS latency ratings may knock the speed down to 1333. We've seen it happen to at least one other user in this very thread. Always best to make sure all of your modules have the same specs.

I don't know which modules Dell includes with new machines (wouldn't be surprised if there are a few different ones that they use). Best bet I think is to wait until you get the machine and use CPU-Z to check the specs of what you get.

 

Thanks, Aaron. I'll put that to the top of my to-do list when I get my machine. A little odd that the speed would get reduced to 1333 just because the CAS latencies were different. I could understand the latencies being "reduced" (actually increased) if mixed values were used -- all running at CAS 11 if both CAS 9 and 11 were used -- but we'll wait and see. CPU-Z should tell me.

Appreciate the tip.

 

The OEM RAM is a mix/match of manufactures. I simply replaced it all with one matching set and called it a day.

As for OC the Quadros. Please keep in mind that these are not gaming cards but pro cards designed with a specific use in mind.

Although they can game (within reason), and do possess a measure of built-in OCability, you would be wise to err on the side of caution and not take them too far out of their element. They are a heck of a lot more expensive to replace than a gaming 680.
