Latitude E6400 Owner's Lounge

I have undervolted my E now, and it definitely does wonders! I haven't tested it much yet, but there is an obvious difference of almost 10 degrees or so. (I got BSOD for index 4 9x at 1v so I will set it to 1.025 and try to run some more stability tests).

A question: I can set index 2 at 0.9250v without BSOD, but even though, I cannot set 1 and 0 lower than that. Why is that? Seems like I could have set it lower if the program had allowed me (in the guide he can get it down to 0.850)

 

This is slightly off-topic, but which carrying case do you E6400 owners use, and did anyone chose the slim nylon case?

I'm looking for the lightest case possible (that is decently constructed and comfortable to carry) that will still accomodate the battery supply and maybe a few papers.

Any cases out there designed for slim 14" laptops which weigh under 2 lbs?

 

I'd check out SFBags.

 

I just received an E6500 and am using XP.
If I adjust the resolution from 1440X900 to 1280X800 comes out poorly.
If you do it on Vista does it work out better.

I know now I should have bought the 1280X800...
I know I can adjust the DPI and so on. Unfortunately I use one software that the size can only be adjusted by resolution. These are financial line feeds by the way.

As always thanks for the help

 

Case? I use this 10 year old leather case I got for free. Someone wanted me to look at a fried laptop to see if it was salvagable, and it wasn't. They didn't want the broken laptop nor the case returned, so after a little cleaning up, it's easily the nicest case I've ever had.

bspiral, if you are within your 21 days from purchase, you can return it and reorder.

15.4" Premium WXGA (1280x800) Display

14.1" Premium Electronic Privacy WXGA (1280x800) LED Display
14.1" Premium WXGA (1280x800) Display

These are the 1280X800 screens available. Any comments on the difference. Anyone have these?

Thanks all

 

Nice voltages. My P8600 crashes at 9x 1.025V. I can't explain about the index 2 voltage. Can you set index 1 at 0.925 and then use auto-adjust. Remember to do an overnight stress test at your proposed final settings in order to confirm stability.

This is my bag:

Made by Lowepro and weighs 1.4lb empty but has good padding. The computer is chosen to fit the bag, not the other way round. I found it several years ago being sold off in a camera shop and is clearly designed for ease of access. I hate the bags with flaps over the front compartment. See the notebook travel guide for more suggestions about bags.

LCDs will always look fuzzy when used at the non-native resolution. If you need 1280 x 800 then consider the smaller and more portable E6400.

I saw a great deal on this laptop on ebay but the screen resolution is Widescreen WUXGA (1920x1200) - I am used to using much lower resolution and am afraid this might make the icons and text very small. Any suggestions or comments? Can I put it on a lower resolution w/out the screen to be fuzzy?

 

When I did a stress test I got an error message in orthos for 1.025 so I have increased it to 1.0375. How many hours should I stress at each multiplier? (I am currently doing a test at 9x and have run for 2 hours).
It is so nice, because before when I did stress test the fast fan ran all the time, now it kicks in after about half an hour and only runs a once in a while

Thank you so much for your help, John.

 

I believe that the higher the resolution then the less the fuzziness because the interpolation process will work better. For example, running 1440 x 900 on 1920 x 1200 means that 3 logical pixels map onto 4 physical pixels. The nearest I have tried is running 1440 x 900 on 1680 x 1050. It looked fuzzy to begin with, but then i got used to it.

I never bother to stress each multiplier but do an overnight test at the highest one then let the voltage do the auto-adjust for intermediate voltages. Lower frequencies mean lower voltages and less heat so they are a less demanding case. If you do want to test another multiplier then it should be the 6x. In reality the CPU spends most of its life on either SLFM, 6x or full speed so it will make no significant different to the heat whether 7x and 8x are optimised.

I also set my final voltage at least one step above the voltage used for stress test to provide a little more margin. It is all about probabilities of an electron not behaving as desired.

I recently ran the wPrime stress test (> 1.2 hour) without the fan going to full speed. I do wonder if Dell have made some unmentioned changes in the updated BIOSes. The temperature stabilised at around 65C. When I originally tested the computer the fan would have gone to full speed after some time at that temperature.
