920XM ES chips decent?

I've seen a lot of people in here have ES chips and I wanted to know how they are working for everyone in terms of reliability, heat and overclocking.

Thanks.

This has been covered already. There's virtually no difference between these and the OEM. CPU-Z sees it as an ES or QS. If not for that, I doubt anyone would ever even know.

920XM ES CPUs

 

Thanks. Any recommended benches or stress tests that I should use beyond 3dmark and wprime to put this chip through its paces before I decide?

Wprime, Prime95, Everest. They're all going to kick the crap out of your CPU. I don't know what CPU you're upgrading from, but a program called ThrottleStop really unleashes the true potential of the 920XM. With it, there is no difference between the 920XM and 940XM. If you're going to be beating up on it, make sure that your cooling system is properly maintained, and that you monitor your temperatures. Have fun!

 

If you can do OCCT, Linx and IBT run for 1 hour each with no errors then your chip will outlive you unless murphy's law decided to check up on you.

 

I'll give that a shot. I purchased a chip that was marked as OEM but turned out to be an ES chip once I got it installed. The seller offered me a refund or a discount if I decided to keep the CPU. So far it's running like a champ and without any tweaking it got me from about 13k to 19k in 3dmark over my old 720qm.

What kind of temperatures should I expect with a 920xm?

-Byshop

 

Without oc idle time mine is about 39-40 degrees celsius in a room with 22 degrees always maintained and full load not more than 74-75 degrees celsius.

I haven't tried to overclock the cpu so far (maybe once from bios up to 5%, but not much difference in temps). I used MX3 thermal paste. Also got MX4, but I am sure it will not make the temperature go down more than it is now and I didn't bother to change it. I have the processor from almost 6 months, no issues what-so-ever...

Hope that helped

 

If you're beating the CPU up to test for stability on purpose, expect to see the low to mid 90s C. For normal everyday usage, 75°C sounds about right.

 

Thanks for the tips. I'm hovering around 45 to 50s while idle right now. Under load I'm topping out in the low 80s at the moment so I'm not too bad, but that was enough to trip OCCT which has a default threshold of 80c. I'll crank it up a few degrees and run again but it appears to be stable. Based on this I think I'll take the discount from the reseller and hang onto the chip. I'll let you guys know how it goes.

I ran OCCT for an hour yesterday with the default threshold cranked up to 90 and it never got above 86. Tested complete with no errors and has survived everything else I've done to it so I called the distributor and he agreed to knock the price down from 600 to 450. I know that's a little bit higher than ES chips go for on Ebay but I figure $50 is worth the convenience of not having to send it back for a refund, ordering another chip from China, waiting for it to show, installing and retesting, etc. Next stop, Throttlestop guide.

Thanks for the help guys.

Funny thing is I've just received my 920xm and it's a SLBLW and not a Q3B8 which I was expecting. Could this still be a ES/QS even though it has a OEM desc .Not that it matters I guess. BTW bought off a reputable seller for £248/398$. what do you guys think?.

 

the SLBLW is actually the OEM version.

 

Thanks...

 

I have a similiar chip, says i7 920XM / SLBLW on it, but CPU-Z says ES. MS OEM 920Xm says the same thing, the numbers under the SLBLW are differant however.

 

Could be dacco, but I'd say it's almost moot. Mine was labeled SLBLW but clearly shows as a Q3B8 once I installed it. In my case, since I was paying for an OEM getting an ES would have been a ripoff had the reseller not agreed to refund me some of the money I paid. Since the ES chip is the cheaper chip, if you actually got an OEM then you got a smokin' deal on a chip that is no worse than the one you were expecting. If it turns out to be a relabeled ES chip with OEM markings, then you got exactly what you were expecting so you're fine there too. There's no advantage to an ES chip over OEM besides the fact that they are typically a couple hundred bucks cheaper, so since you already paid a price in line with an ES chip ($400 US range) you are pretty much set either way.

Thanks DR650ES/Byshop...My guess is that they are relabling these CPU's as OEM to catch people out and up the price by a couple of hundred dollars. Lesson for today....Never trust what is stamped on the CPU and always buy from a reputable seller. Will update on if it's OEM when I get it in my R2.
