Safe to buy an ES CPU?

post #1 of 11
Thread Starter 
My Thinkpad T420 is in the mail, and should be here tomorrow. However, I have been thinking about taking the machine apart and replacing its Core i3-2310M with a quad-core Sandy Bridge processor.

However, the Core i7-2720QM (the model I am looking at) costs more than $350 at retail.

There are some other options, though. I can buy an ES version, and that will set me back around $188 via eBay. However, I am wary of buying an ES CPU, since they are not final silicon.

Any advice on this?

Yeah. It's not soldered, though. I've checked the repair manual. It plugs into a G2 socket.

ES hardware is not meant to be sold. If Intel found out they could go after the seller and/or the buyer to recover the CPU

True... But has that ever happened?

I've been reading that buying a QS (qualification sample) might be better, since they are practically the final product shipped to OEMs for final testing. They are a bit more pricey, though, and a retail chip is only $50 more expensive.

There is no guaranteed that the ES you're buying will perform or be as stable as a retail chip. You're doing this to save money but you could end up with an unstable chip that may die in a few months. On the other hand, you may get lucky and get an ES that is almost identical to the final version... I personally wouldn't take the risk.

I was thinking if trying this again. Bought a m35x toshiba that had a celeron and put a centino 1.6 in it a long time ago. The boot screen even changed from pentium to centrino logo on its own after the swap.

The chipset is the same and a b940 has the same gpu clock speeds but no quicksync etc. Ive seen i3 on forums swapped for 2630qm. I may be trying the swap in the next month. B940 laptop for 300 and 2720qm for $112 shipped. Add 8gb ddr3 ram for $50.

Guarantee its the fastest $460 laptop out if the chip pans out.

Will it have proper cooling going from an i3 to an i7?

While I don't condone purchasing an ES chip, as long as it is a compatible socket, it should work. Make sure the TDP is within the stock CPU though.

I'd wait and buy the retail chip, or deal with the i3.
