840qm cpu-original box vs ES vs QS vs oem

Some people said that qs have more over clock power then original qm or es..But how is that happen? aren't they all are same 840qm family?

How should I know if I got qs,es or original?

And which one cover's warranty if something goes wrong?

Also how should I know that if I got a counterfeit.re-mark CPU?

 

It used to be that QS or ES CPUs would have unlocked multipliers, or would otherwise be able to overclock easily, but with the more recent generations, QS and ES chips seem more often to be crippled than to have unlocked capabilities. And this happens because they're prototypes, which is why they're qualification samples, and engineering samples.

CPU-Z should tell you if it's a QS or an ES chip.

And the sale of QS and ES chips is technically illegal, so no, there is no warranty coverage from the manufacturer on a QS or ES chip. Period. The seller may offer a warranty of sorts, but this depends on the seller, and is unlikely to cover more than the chip itself.

As for counterfeit remarked CPUs, you'd have to compare the markings to what something like CPU-Z would tell you.

 

Good Answer. but can you help me by tell me what will show in the CPU-Z if is QS or ES? cause I just purchase an "HP OEM" 840qm. I want it to know if sell some how re-mark it or cheat it on me.

 

Cpuz will tell you the model of you CPU and it's frequency, you can then compare that with the informations available on intel website. ENGINEERING SAMPLE will be displayed if it is an engineering sample. You can also google the revision and stepping of your chip, as qs and es CPUs generally have a specific one. And if you are still not sure, you can directly email intel. They will be more than happy to help you.

 

The only one I would think that would be covered under warranty would be an OEM. Also the only one I would even consider buying. Sure ES may have certain things unlocked, but I dont want to depend on a "sample" chip.

 

The OEM ones are the most reliable and you can call genuine articles. ES and QS are actually given to people to test before CPU is produced and they're supposed to be returned to intel so anyone selling it to you is selling stolen property. Many people don't seem to have qualms about using them but if one day intel starts chasing , you'd be in trouble. The QS ones are better than ES and pretty much almost like OEM ones. ES is ok but you need get the proper one or you'll be in trouble.

 

It sounds like by "in trouble" he meant "you'll have problems with the chip."

 

Well, it's more that anyone with an ES or QS CPU that wasn't given to them directly by Intel is technically in receipt of stolen merchandise, so if Intel chose, they could demand that those CPUs be returned. Now the likelihood of such an event happening is pretty low, but with AMT and all of the other things that Intel seems to be adding to their chips these days, the chances could get higher and higher. Oh, and of course obviously, as I stated before, there's no warranty, so if you do have any trouble with the chip, asking Intel for help will get you nowhere, and may even have Intel demanding that you hand over the chip.

Think of it like (illegally) downloading music. The chances of most people that do this getting caught is pretty low, but if you do get caught, and someone like the RIAA decides to prosecute...

 

*shrug* And songs were illegally downloaded for years before the RIAA started leveling lawsuits against individual people. I'm not saying it's something that's going to happen anytime soon, after all, I noted that the likelihood of such an event is pretty low, but with all the communication features Intel is starting to build into their CPUs, they may decide to start remotely "killing" QS or ES chips if they feel this market is cutting too far into their profits (doubtful, but you never know). Depending on the fact that someone "doesn't care" (at least for the moment), is always risky business, and should be acknowledged as such.

As for where these processors are coming from, that's always been a very interesting question. ES and QS CPUs used to be relatively rare; it wasn't really until C2D or core-i that they started becoming as readily available as they are. Of course, with core-i, they also started "losing" a lot of the features that used to make them as attractive to the modding crowd, such as the unlocked multipliers (on previously locked chips). I've always wondered if perhaps all the new ES/QS chips are actually Intel "discards" from their regular OEM chips that have been remarked, but I don't know that anyone's ever found out.

 

Whichever way you want to go , its your choice. Unless an QS had a much lower price than the OEM one , i wouldn't get the QS. I doubt i can install the CPU in my laptop anyways.

 

I highly doubt Intel would go after present users of ES chips. In reality those mostly are older generation chipps out there right now. Be that C2D's or older gen iCore's etc. If they were to stop it they would go after the sellers and stop availability.

as far as off loading chips, it is a good probability Intell takes silicon that is out of spec and sells them as "Test" CPU's In this way Intel makes money but doesn't need to place a warrenty if it truly is bad and if it ever dies or performs badly Intel's reputation is still in place too. It would be a Win-Win for Intel to make money off of scrap.

These CPU's are probably meant for jobbers to test defective systems as they come in to be sure the old CPU isn't of issue etc. This also frees up OEM cpu's from neing used in the testing phases so Intel can keep a better eye on what the consumers are actually purchasing for systems. Does Intel care about the 0.01% of consumers as tweakers that will use an ES or QS, I highly doubt it as we are insignificant statistically.................

 

I'm about to buy an ES Q9200 Core 2 Quad CPU. I would actually prefer to buy OEM but I can't seem to find a single Q9200 for sale that isn't ES.

 

there never was an OEM q9200 released, they are all ES, the QAVR is also known as qx9200 as the multiplers are unlocked.................

 

I had a QS X9000 and I had zero problems with it.

 

QS's come at an earlier stage than ES's. They represent the first wave of a CPU as it goes through validation and verification. In practise these means the earliest revision/stepping.

ES's come after QS's at the last stage of pre-market.

It's no longer a norm for ES's to be unlocked. Some are, some aren't. ES's also don't necessarily mean better yield/hand-picked chips that overclock better. They may or may not depending on the silicon.

If you install an ES version then CPUID programs will report CPU name string followed by (ES) or Engineering Sample.

ES's aren't sold to the public. They carry no warranty of any kind.

 

I thought QS came after ES. Quality sample vs Engineering sample. My QS X9000 came with working temp sensors while the ES didn't.

 

Did you check what stepping your CPU is in CPU-Z?

 

But the Core 2 on ebay are ES, and the Core i on ebay are QS. I really think they just changed the name of it.

 

It's best to track down the Spec code number. On retail/OEM parts it starts with Sxxxx but on QS/ES's from what I've seen over the years it starts with Qxxxx. By following up on this code you can track down their specification.

From what I've seen over about 10 years or so ES's are a newer revision than QS's.

 

From what i've seen QS have been newer and more reliable than ES

 

It was a Q174. All X9000s were CO steppings.

 

That's likely because the X9000 wasn't the first in the series of Core 2 Duo's based on the Penryn core. By the time these were released the C0 stepping already existed out in the open and so formed the base for any future releases.

Prior to a new CPU architecture launch there's a run up to it as it matures and consequently its revisions change correcting any/most errata before the big day.

 

I thought there were some E steppings. I've heard for X9100 though that the E steppings are better.

 

Yeah the X9100 has an EO stepping.

 

The X9100 is both available in C0 and E0 stepping but the latter is very rare, I've only seen it once or twice compared to the array of C0 variants out there.

The T9900 meanwhile is only available in E0 format but that lacks an unlocked multiplier.

 

laptopmonkey sells X9100 ES QHBQ stepping E0 on eBay.

 

Shirleyfu1117 sells EO X9100s on ebay also.

 

Try finding an OEM (non ES) E0 X9100 and you'll see what I meant above

 

I doubt anyone buys X9100 OEM's nowadays with ES being pretty cheap.
