Hello,

I have problem with my Asus g74sx.

After replacing the CPU I5 2410 ----> I7 2720 ES and pressing the power button, cpu fan is running, but screen stay black.. If i replace the old cpu i5 2410, notebook boots up, not problem,

Any suggestions on how to get this CPU to work in my Asus G74SX ??

Thanks!

Did you try "Load Optimized Defaults" (F9) to reset the BIOS?

bios update, perhaps? [latest is the 203]

Bios 203

I pulled out the battery, resets the bios, it does not help. It turns on, lights bulbs,cpu fan works, but the screen remains black .. Maybe the processor is not working properly?

Yeah, I think two likely causes are that (1) the CPU is faulty, or (2) the BIOS does not recognize that CPU as compatible with your system.

but if it is the g74 and has the 203 bios.. it should recognize no? i think CPU is faulty, too

You'd think, yes. But perhaps there's configuration information stored in the BIOS that only matches certain CPUs with certain systems.

A dual-core i5 (rated at 35W) to a quad-core i7 (45W) is a significant change, and it seems possible (to me) that the systems may be designed to accommodate one or the other, and the BIOS "knows" this.

you have some reason BUT when we go to the support page there is only one g74sx! And this model can be bought with (at least) 3 different CPUs. So, if the support page only shows 1 g74, and 1 bios file (the 203 serves every G74), IMHO the info inside the bios regarding controlling the cpu should know which cpu is installed and how it works. and that's why I THINK the cpu is faulty. But your point of view is valid too

dual-core i5 (rated at 35W) to a quad-core i7 (45W) is a significant change, yes it is, but once again I THINK every other hardware is the same (motherboard, gpu, ram, power adapter) so it is only a question of the bios 'handling' a different cpu.. which is also sold in the same config

I was proposing two possible causes, not making an argument or disputing what you think.

No worries.....I think either cause could be correct....or maybe even something we haven't thought of.

But either case, whether it's faulty CPU or motherboard+CPU mismatch recognized by the BIOS, I think it sounds like a fatal error and he probably will not be able to get THAT particular CPU to work.


@antirandom: After you have installed the i7, are you able to F2 into the BIOS and see the appropriate CPU data?

No, this is not possible, the keyboard does not respond, only power button works, someone put an identical processor on Asus G74?

I think that CPU is either faulty or not configured in a way that your consumer platform can use.

An ES chip is one of the first made. It is issued to vendors for the purpose of creating and tuning companion products for compatibility reasons. They're actually supposed to be returned or destroyed when testing is finished but some ethically challenged vendors turn around and sell them for a profit.

Part of the reason for the return/destroy policy is that early ES chips may not work in all boards and require different microcode. People trying to use these chips may find limited/no functionality.

Thats good info to know Xero...I see lots of ES CPUs for sale on EBay all the time, and have almost been tempted to get one (an i7 880 to replace my 860, just for the extra 100-200 MHz I could squeeze out of my overclock). Will steer clear of ES from now on.

I didn't know they did this. so it is normal that the bios cannot handle this CPU. Perhaps BIOS 'is thinking': what the hell is this CPU?

P.S. thanks for the excellent information!

Exactly. A late production ES chip may have the same stepping, CPUID, and microcode but it's a real gamble. If you get one of the early ones you may never get it to work in certain boards. That's exactly what happened to me before I knew what ES really were. :(
