Hi! I have a Dell studio XPS 1647 laptop which came with 4gb memory 1066mhz, core i5 430m processor, and intel PM55 chipset. I upgraded the memory to samsung 1333mhz 8gb. I just bought a core i7 820qm (shows Q3B9 ES on the CPU) and after installation, i hit the power button and the media keys flash from left to right and than "dicrease volume" icon flashes and system does not boot! Only 3 volume icons light up and the one in the middle (decrease volume) flashes. Now I know that the prior cpu I had was an Arrandale corei5 430m cpu 32nm and the core i7 I have is Clarksdale 820qm 45nm cpu. As far as I know, the PM55 chipset supports both core i5 and I7 cores. What might be the problem? I really want this cpu to work. I contacted the seller and he said it was %101 functional!
I POSTED THE VIDEO HERE: http://www.youtube.com/watch?v=KCXxcLmBOOQ
Here is my current upgraded specs:
Dell Studio XPS 1647
Core i5 430M Arrandale (BIOS upgraded to A07)
8gb Samsung 1333MHZ
Seagate 500gb 7200rpm
Intel PM55 chipset
Bluetooth Edr 2.1
1600X900 wled screen.
Any help will be highly appreciated...
What you purchased is an engineering sample CPU - which, beyond what follows, is illegal for sale. Intel requires non-disclosure agreements when it sends engineering samples to manufacturers, testers, etc. which preclude selling the samples when they're done with them. Such CPUs are routinely used in durability testing - overclocked, over-voltaged, throttled beyond redline, etc. -- in other words, they're designed to be abused, and many have been. So, even if you obtain one, they're not reliable.
Beyond that, they're not multiplier locked - so even if they're in working order, they won't work on a system that doesn't have a provision for manually setting the multiplier. Your Studio is such a system.
Translation: this CPU is not going to work on your system. Send it back for a refund and buy a warranted, for-sale authentic Intel production CPU.
The ES in the CPU code you listed means Engineering Sample. These WILL NOT work in your system (and are VERY, VERY risky buys).
Engineering samples are the beta software of the software industry or the prototype cars of the automotive world - they are NOT intended for sale.
I really appreciate your help. I contacted the seller and he will refund me once he gets the CPU back. I checked every single 820Q CPUS on Ebay and every single seller is selling ES models! I don't know why it is illegal since they already have these CPUS out; I mean is somebody sells these ES models before the CPU is out on the market, I would think that is illegal but once they are out, the engineering samples are already useless. Anyways, this is not the issue anymore. I already bought a 720qm from a different seller and he verified that this CPU is OEM not ES. I really really appreciate your help as without your post I would not know about this. Thank you soooo much. Have a nice day...
About the only way EBay sellers can make money on CPUs is to sell either high-demand discontinued models, or engineering samples. There is no way they could make much money on selling legitimate production CPUs when large companies buy them by the thousands, with discounts accordingly.
The biggest issues with engineering samples are that they've been used in ways that can cause damage - you have no way to know whether the CPU is in fact in working order -- and the damages can be insidious (resulting in calculation errors, etc.). You also have no way to know whether their lifespan will be a normal one, and without the clock multiplier lock they simply won't work in most production notebooks.
It is indeed a violation of Intel's NDA to sell an engineering sample - presumably if Intel wanted to it could trace the CPU serial number to the original owner and perhaps bar them from receiving future ES chips.
Once again Thank you so much for the help. Think about not having an internet back in the days. It would take days months to figure out what is wrong with my computer. God it is so easy nowadays... Last question: I have the core i5 in the computer right now until the new 720QM (Not ES) arrives on Monday and I got into Bios and it shows my Rams as 1066MHZ! I have 1333MHZ Samsungs 8GB and why is the system showing them as 1066? As far as I know core i5 support max 1066 and would that be the problem? The CPU is limiting the memory speed? So once i install the core i7, would it work as 1333MHZ? Thanks...
This system does support the CPU in question, so that would mean one of two things:
Either the CPU isn't what it appears to be, or it is faulty.
Did you purchase it at retail from a valid reseller, or on the wilds of EBay?
What is the S-spec (Code beginning with S) on the CPU?
I don't think the 2 cpus that I bought from Ebay would be faulty. I mean it is exactly the same problem. The guy who talked to said he got this NEW from Intel as OEM. He has %100 feedback as well as the other guy who i bought the ES model. The code says: SLBLY V012A008. I really don't think it is the CPU honestly !
