ASUS A8SC-A1 CPU upgrade?

I currently have a T7100 in the system. I was looking at upgrading to either a T8300 or T9300. These both have 800MHz FSB and are 45nm. I have the latest BIOS (302) installed.

I'd prefer to go with the T9300. Anyone know if it will work??

T9300 - 35W, 2.5GHz, 6MB Cache, 800MHz FSB

T8300 - 35W, 2.4GHz, 3MB Cache, 800MHz FSB

Both cpu's will work in your notebook. SImply take the system apart carefully. Use proper grounding bracelet and use good screwdrivers. Once you have the system apart you can simply swap the cpu. Just turn the small screw on the socket, and then you can remove the T7100. Than install the new cpu. Than turn the screw to the lock position.
Apply arctic silver or a comparable thermal compound to the processor die. Than install the heatsink and put the system back together.

Let us know if you need any more help

Thanks for the info. Is the T9300 a good choice? Is it going to run much hotter that what I have now? I'm not too concerned about battery life, but I don't want the keyboard to burn my fingers when I'm typing either.

Is there another CPU I should look at?

 

Actually, come to think about it, wouldn't the T8300 and T9300 run cooler than the T7100 you have right now?
Yes, they would be running faster, but the new 45nm cores use less voltage and thus generate less heat.

 

That's actually what I thought, but I see conflicting statements in reviews. Not professional reviews, but basic user reviews. I'll just have to try it and find out.

 

actually, your only part right. The cpu will get up to the same temperatures, it will just take a little longer for the new 45nm cores to get to that temperature.
Reason being, the temperature of the processor is almost entirely due to the bios coding which tells the fans to come on. Most system fans come on once a 160F has been reached, so both will get up there in temperatures. Since the T8300 and T9300 are 45nm and more efficient with their power, they will simply take maybe an extra 5 minutes or so to get to that thermal threshold for the fans to come on.

Ether cpu is a good choice. The T9300 is about 5% faster, so if you can get it for about the same price as the T8300, I would go for the T9300. But dont spend like $100 or more to get the T9300 over the T8300.

Installation wasn't as easy as I first thought. There is a cover on the bottom that exposes the Video card, Ram, CPU, and heatsink. I had hoped that it was as simple as taking out the heatsink, removing the cpu, and installing the new one. Unfortunately for me, the bottom of the case doesn't allow you to just pull the fan/heatpipe assembly out. You need to get the case out of the way first. I had to pretty much disassemble the whole thing to do it. Wasn't exactly quick, but lucky for me I've probably taken apart 750+ laptops to replace various parts.

Anyway, everything seems to be working great. The laptop definitely feels much more responsive just in general tasks as well as WinRAR. I've been folding with the SMP client for about an hour now and my temps have only hit as high as 56C. Haven't tried any benchmarks or games yet.

 

nice upgrade, I am glad it worked so easily for you.
Wow 750 + laptop tear downs, that is impressive. You have most everyone beat by a longshot.

I worked for a company that was also an authorized HP repair center. So when I wasn't doing service calls I was in the shop replacing screens and motherboards on HP laptops. Later, I was a Network Admin at a school district. I was in charge of roughly 600 HP laptops that were utter piles of crap. Spent a lot of time replacing parts in just about every one of those computers. Kids and laptops do not mix.

 

Bad news. It looks like a penryn CPU won't work in my laptop...even though it does?

I received this from ASUS tech support today. I had asked them if the cpu was supported about 2 weeks ago.

 

Conroe..?? Thats for desktops. Are they referring to the 65nm CPUs..??
