dell to fix cpu throtling issue in next bios update....

i even mailed micheal dell regarding the issue of cpu staying at 930mhz or at multiplexer 7 at most of time..

they say that they are gonna fix this in the next update which is scheduled to be released with in jan15th...

i bet even though updating the bios wont help in boosting the performance without enough power...

they say that they are also considering about the 130W adapters...

 

Well I hope I'll get the 130w adapter and the bios update.
My only reason for chosing dell was the 12% due to a thing with the school.
I hope the 12% are worthing all this worry :S

 

Hopefully this doesn't happen.

Oh God...don't scare me. I just know I won't be the first to install A4...in case they do something like block 130W adapters or something else that would me off further...

 

If you brick it then it will be a good excuse to get the 1647

 

I do not want the 1647. Quad core>Dual Core.

 

Isnt the cpu upgradable? same chipset? At least you wont be stuck with a discontinued model or soon to be( 1645)

 

this is great news if dell follow through..

 

You can't upgrade the CPU on Dell laptops (at least I don't think so) and isn't the i7 and i5 architecture different?

 

Yeah, socket's different. But you could get lucky (check ark.intel.com, some i5 mobiles have the same socket as an i7 mobile. Perhaps if dell hasn't f*ed up the bios too much and used the "right" socket, you could change the cpu fat chance)...

 

Not by too much, 2.66x2=5.32, 1.6x4=6.4. About 20%. And new cpu has AES accelerate if you use full disk encryption.

 

20% that I need. I've actually hit 100% CPU usage several times (not benchmarking) real world use. So I'll stick with my i7.

 

Core i7's don't have AES acceleration, but i5's do? Seriously?

 

Yeah.. Just like they replaced M1330/M1530 with motherboards that had "revised" chips to prevent failure of the nVidia GPU..

Oh wait..

 

Uhhh...It doesn't quite work like that. You don't multiply the core count with the core clock to determine performance and then compare.

I have a Pentium D @ 4ghz. 2x4ghz = 8ghz. Looks like my 4 year old CPU is better then anything that came out today, woo!

 

2 questions to anyone willing to answer.

1. It's my understanding you don't just multiply the core count by the clock speed to figure out performance, so how exactly do you gauge it?

2. AES Acceleration?

 

Simply multiply frequency by core number is just my rough estimation of performance since they use almost identical architecture. There's no other better way I am aware of.

Look at 2nd chart on that page.

 

Benchmark the processor, there's too many variables to performance to make stuff up on paper. It's not very deterministic anyway, maybe on the same piece of code, but not in general.
