Replacing the processor, need information on heat-sink.

Hi!

I am getting my processor replaced by DELL. After a delay, and a lot of problems, they sent me the processor, but no heat-sink, or an Engineer, and I have been waiting for 5 days now.

So, I have to buy the heat-sink myself, as I have to leave for my home, I am in some other city to pick this up for the last 5 days (they don't deliver/work where I live). I called DELL's tech support to ask about this, but they are clueless (anyone who says a 32 bit OS can't utilise full 4GB RAM because some space will be taken by MediaDirect, are).

My old processor is T5250, and the new one is T7700. I want to know which heat-sink to buy, as I have been told that there is a different Heat Dissipation Standard (??) for different processors.

Also, is there anything else I need to know before getting my processor replaced (by an engineer)?

 

Why can't you use the old heatsink that came with the machine? There's no way it's permanently connected to the old chip unless it's like a P4.

 

I was told by DELL that there will be 3 parts the would be needed and will be delivered by them. A processor (received), glue-box/thermal pad (received), and heat-sink (not received). Also an engineer to replace it. So, if I use the old heat-sink, it wouldn't matter? The DELL tech support told me that there are different heat-sinks for different processors. Then the same girl told me that they ship the same heat-sink for every processor. I don't know if it can come out or not or what it is. I gathered as much information as I could from the Internet and my friends, and rather than call the tech support back, made a thread here.

If I can use the same heat-sink, that came with my notebook, then it'd be awesome. But I don't know about it.

And when I finally got ahold of the girl handeling my case, she asked me to buy the biggest warranty indirectly "This is a NBD service, had you bought blah-blah, you'd be covered by this-that". And I got the parts on 24th of this month, talk about NBD!

Thanks!

 

Honestly I don't think there should be any problem with using the original heatsink. I don't think a single machine could have fitting heatsinks. Just make sure you re-apply the thermal paste and such.

 

Thank you! Finally, for the 20th time (this is the last time, I swear), I'll see performance boosts with T7700 when compared to T5250, right? I mean noticiable.

Thank you!

 

Might not be completely amazing, but yes there should be a significant difference.

 

Thank you Commander Wolf, you're the best!

 

Hi! I have replaced the processor, but there are many things that came up!


1) When the technician just replaced the processor and booted the notebook, in the BIOS, it showed -

So I called the DELL tech support yet again to ask how could I reach the full 2.4 GHz, and the person there said that since my motherboard only supports 667 MHz, it will show as 1.6 GHz, but it will work as 2.4 GHz. Is it true?

Regardless, after sometime (after we tightened the screws), it showed it 2.4 GHz, as it should!



2) I checked Intel's website for my motherboard's specifications ( link here), and it says 800 MHz front side bus support and Support for dual channel DDR2 667 MHz memory technology.

My processor has 800 MHz FSB, and my RAM is dual-channel at 667 MHz. So my second question is, will there be a limit on my processor's 800 MHz, like the guy said, because I can clearly see on the Intel link, that my motherboard supports 800 MHz. Or does the fact that I have 667 MHz RAM, it will limit my processor's FSB to 667 MHz as well?




Will both my processor, and my RAM, be able to utilize full 800 MHz FSB and 667 MHz respectively (please check the link provided as well, I'm not good on these things)?

 

The cpu supports Speedstep which basically dynamically changes the cpu frequency depending on the load on the cpu. It will also work on battery as well as A/C power to maximise battery life and heat output. Nothing to worry about as long as your cpu is maxing out when you stress it. if you want it to run at max all the time change the Windows power profiles to "Always On"(XP) or "High performance"(Vista). If this doesnt work then look in the BIOS if there are options to disable Speddstep or something similar, if there arent then you can try controlling the frequency by utilities like RM Clock or NHC.

The dell technician just gave you a BS answer. The max memory speeds supported by the i965 chipset is DDR2 667(333MHz) and FSB of 800MHz.

 

That's what I wanted to know! Oh man, the DELL tech support!

And one thing, DDR2 667 MHz is actually 333 MHz? Or you mean to say this motherboard will support only 333 MHz (it says it can support 667 MHz on it's webpage though).

Thanks!

 

Well, the actual data frequency of DDR2 667 memory is 333MHz. Further the memory cells run at even lower frequency of 166MHz. Due to the fact that these memories are capable of transferring data twice per clock cycle(hence DDR) they are labeled at twice their clock speeds. Basically they offer the same throughput as SDR memory running at 667Mhz.

 

Thank you for your help miner! I hope my notebook (in my sig) is able to carry on light work (like Winamp, uTorrent, MSN Messenger, Opera etc) for at least 3 years (will it?) without any stutters. I know it won't be able to plays 2008's games.
