The chip is being fed 1.388vcore. Thats way too much.

Yes, a BIOS update to add support for MEROM would fix the problem. Once it correctly identifies the CPU, it will be able to provide it with the correct voltage, and cause it not to run at 95C.

If you run Merom + E1405 as-is, right now... speedstep doesnt work right, and it it overvolts. So, when on battery, you are always running ~1ghz... then when plugged into A/C, you are running at 95C under dual prime.

Hope this helps

sound likes a bios update would do it... although would dell really offer a bios update? i think only a tiny fraction of a percent of their customers would actually upgrade the processor in the laptops....

I got an E1405. To replace the processor is 5 minutes since it is in the bottom of the laptop via a panel. Totally easy so I could see where that would be a good thing to upgrade to merom...

Have you tried flashing the bios w/ Dell's recently released A10 bios and a Merom chip?

A01?

i dont see an A10

so from what you can see it probably could be successful with a new bios update that would allow for lower voltages for merom?

Yes, there is no doubt that dell will release a new BIOS with the correct support for MEROM.


Dell releases new BIOS updates all the time. When MEROM comes close to launching, you will probably see an A02 BIOS be released.


The E1405 is an awesome laptop to get for people that want to add MEROM later. With only 6 screws in total, it makes it SIMPLE to upgrade.


I recommend Shin Etsu TIM (thermal interface material) It is very simlar to what OEM dell uses, and is VERY good. The thermal pad actually melts when heated, causing the excess pad to melt and ooze out a bit to the side of the CPU, causing a PERFECT layer of thermal interface material to fit between the CPU and the heatsink. Arctic silver 5 is often too thin on these types of heatsinks, and generally, dont yeild the same results as Shin Etsu

You can buy them there, great for people that want better cooling on their graphics card and their CPU.

Dell uses two types of TIM, one is black with a metal inner layer, which doesnt work as well. The other is a compound that is very similar to the shin etsu. The shin etsu always works better than the OEM dell compound. I recommend anyone to give it a shot. Looks oem too, so for warranty work, dell cant call foul play.

The idea of a heatsink is that it is supposed to be able to disperse heat well. The only point of thermal compounds is to make sure that the heat gets from whatever is hot (cpu, gpu whatever) to what disperses the heat (heatsink). Therefore Arctic Silver 5 is not too thin, the whole point is that it is thin. It is simply taking the place of air (which conducts heat horribly) in between the cpu and heatsink.

For regular CPU's and GPU's that use more traditional heatsinks, i'd agree.

But these heatsinks, from my testing, seem to do better with shin etsu.

The shin etsu gets extremely thin once it heats up, but is easy to apply perfectly, because it is a pad.

I dunno, just what i got from testing. give it a try, i think you would be suprised

Just curious what speed of Merom you have? I have a 2.0ghz Merom in my M1210 and its working great and the voltage is 1.34 when at full speed which seems right where it should be compared to the Yonah voltages and 1.196 at 1ghz. If you had a higher speed I could see that 1.38 might be the correct voltage at full speed like that.

Would anyone have pictures of the processor on the chipset of an E1505? I want to see how exactly i can access the proc.. and oh, if u also have pictures of the graphics proc in the E1505, that would b appreciated as well.

thanks in advance

You can find the instructions to access the processor in Dell's website. I posted some pics with the graphics processor of the e1505 a couple of months ago. Just do a search.

I thought Dell was switching to AMD. You sure they will support it?

I don't know if they are actually switching, their 22year EXCLUSIVE contract with intel is over though. Either way it would be a very simple BIOS update to lower the voltage

lol


AMD couldnt even handle the capacity if they tried.


Anyway, the amd option is just going to be for servers, starting in the fall. From there, who knows.


Anyway, it is just a BIOS update, which DELL will release because Core 2 DUO will be launched, and supported by all notebook makers.
