i bought a c2d (e4400) off ebay the other day and while researching i found that there is 2 stepping types, fla98 (good overclocker), and fla3f (crappy overclocker). well the thing is my cpu say fla5f. What the crap?!?!? there is nothing on intels site or the internet so maybe you guys can help me on this.
thanks!

More about : unknown rare core duo

April 13, 2008 3:53:27 PM

Not exactly sure.. the stepping are generally a letter and number, like : G0 or B2.

What your listing is I think the sSpec number:

Intel® Core™2 Duo Desktop Processor

I think you may be misspelling something, the closest I see is:

SLA98 2 GHz E4400 06 800 MHz 65 nm M0 2 MB LGA775
SLA3F 2 GHz E4400 06 800 MHz 65 nm L2 2 MB LGA775

Which are E4400. Not really seeing anything close to "fla5f"
April 13, 2008 4:32:36 PM

i know, thats whats so confusing. just to be sure, its the number on the processor right after 4400. it definatly say 5. maybe i can get a picture.

I've seen chips released that aren't even on the manufacturer's website. I just bought a 5400+ Brisbane which isn't even on AMD's website. Boot it up and run a program like CPU-Z. it may be able to recognize the real stepping.
April 13, 2008 5:04:13 PM

so whats the likelihood that its better than the others?
im starting to get kind of excited.

Well, when I googled it I got a bunch of pages about malware. I don't know if that is a good sign. Maybe it has some preinstalled on it :lol:

Yep the SLA5F is a 2Ghz Pentium 4 with 2MB Cache 800 Mhz, Socket 775

Never heard of a 2Ghz P4 on socket 775 - maybe its a pre C2D - who knows

Youve been had...

Even if it is a E4400 its a drop out from Intels labs

you never now it might even be a rare one...

Run CPUZ - google it and let us know the results....

interesting
April 13, 2008 8:07:16 PM

i don't have a motherboard to test it on right now. it should be here within a week though. thanks for the interest!
April 13, 2008 10:57:38 PM

I certainly wouldn't trust those 2 sites as being correct. I bet it's just an e4400, but perhaps an unreleased stepping. Unfortunately, that could mean it's defective -- why else wouldn't it be released?

April 13, 2008 11:29:16 PM

i sent a question out to the guy i bought it from but he hasn't gotten back to me yet, probably will monday. he also sells these weird pentium extremes that come overclocked to 6 ghz instead of 3.7 or something.
search selldemon915 on ebay, hes only got 10 left.

Those chips are Engineering Samples. Don't know how he got them. Btw, aren't ES chips distributed only to few people?

April 13, 2008 11:47:13 PM

why dont you jsut email Intel, you wil lbe fix asap, if its a rare ''unrealeased'' cpu, they will be happy to find who sell it :p  maybe a intel tech who need money lol
April 14, 2008 12:03:42 AM

Those chips that selldemon915 is selling on ebay look rather fishy. As a matter of fact the item descriptions for the chips he has sold and gotten feedback on are all very similar. He claims the chips run at 6 Ghz NOT OVERCLOCKED! Come on. The guy is full of it! I would return your chip, get the money in your hands, and buy from someone reputable.

Your first mistake was buying a CPU on ebay. I would never buy a processor on ebay and most of the people on tomshardware probably wouldn't either.

Just my 2 cents.

April 14, 2008 1:01:11 AM

well i want to test it first to see if it works. i can't get a c2d on newegg for 75 bucks can i? maybe it will be ok.
i am going to try to contact intel too.
thanks guys.
April 14, 2008 1:28:52 AM

i bought a E6400 on ebay and im happy with it, low price, i put more money on mobo and gfx card
April 14, 2008 3:10:02 AM

I'd definately contact intel about this, if it's an ES they might be quite interested in it. I heard of one guy getting a free extreme processor for turning in an ES that was sold to him. Then again I think ES's are often unlocked as well aren't they?
April 14, 2008 3:37:26 AM

what is an ES?
and a free processor would be fricken sweet. my new board wouldn't handle an extreme, but an e8400 would be nice. ;) 
April 14, 2008 3:47:10 AM

You can't get a C2D per se for $75. You can get the E2160 for $75 which is a C2D with 1MB of L2 cache instead of 2 or more. The E2180 overclocks well. My E2200 is running at 2.9Ghz with the stock cooler and Arctic Silver 5.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

E2180 for $70 USD
April 14, 2008 4:01:19 AM

good point. well im bankin' on intel saying, "oh! you found our lost c2d! heres a bag of 100 dollar bills and a 9800gx2! thank you oh so much!"
but thats unlikely.....
why would they give me a graphics card? oh, its midnight im losing my mind.
April 14, 2008 4:01:58 AM

A few months ago I got a Q6600 on ebay with the stock HS for 225. Works great I have it overclocked to 3.38 currrently.(Not using stock HS)

here is a picture, it most certainly says 5f...
http://s277.photobucket.com/albums/kk51/customisbetter/...

Upon closer look at the picture, I see that it says '05 on it. So it's made in 2005, yet the E4400 was released during April 22 2007...some sort of time warp here?

The earliest Core2duo was released during 2006, so obviously the cpu you have is either a fake or an ES.
April 14, 2008 5:32:34 AM

if it is ES, return it to intel. they might be interested in how it reached ur hands.
April 14, 2008 6:25:38 AM

1) Engineering Samples are laser etched: Intel Confidential" on the integrated heat spreader.

2) 05 does not mean it was made in 2005. The 05 is a trademark re-registration date or a patent date.

If your motherboard BIOS identifies it as an E4400/2.00GHz/800MHz FSB/2MBL2Cache then you have an E4400 processor.

April 14, 2008 6:34:51 AM

Strange. That chip was packaged (ie bga attached) in Taiwan in the second week of 07. The SLA5F designation is for plant, line, and location.
At the bottom is an alpha-numeric sequence. It is Q= malay, 7 = 2007, 02= week and the rest is id code.
April 14, 2008 6:46:34 AM

Doubt its an ES TBO.

They normally have different markings.



Contact Intel regardless, they should be able to help regardless.
If someone is selling suspect/lowwer binned parts, they will be VERY interested, as these chips can hurt their reputation.

There usually is a nice reward for an ES, not sure in your case tho... u can always ask nicely.

Contact the seller see what they say... if anything.

Test the chip. If u dont get the answer ur looking for out of either, and the chip works well.... YAY2U.
If it doesnt work as advertised... paypal dispute here we come.
April 14, 2008 7:16:39 AM

You probably should have scouted the seller a little better than you did. I'm thinking you got ripped off.
April 14, 2008 8:25:54 AM

Looking at his "6 Ghz" processors again, I am way thinking you got ripped off. ES IHS's don't have nothing on them, they have Intel Confidential at the very least. He has no credibility, and I am thinking you should rate him down.

Just checked a processor he had for sale.....

THIS IS A NEW LG775 NEVER TESTED. I AM NO LONGER TESTING THESE CPU'S, THEY ARE NEW WITHOUT A SCRATCH ON THE TOP. THESE CPU'S ARE RARE THEY ARE ES CPUS. I TRIED MINE ON A 775VM800 MOTHERBOARD AND IT WORKED AT 3.73 GHZ WHEN I UNDERCLOCKED IT AND I RAN IT AT 6GHZ NOT OVERCLOCKED WITHOUT IT OVERHEATING. . LOOK AT THE PICTURES AND ASK AS MANY QUESTIONS AS YOU NEED. i WAS TESTING THEM AND HAD SOME THAT RAN ONLY ON A ASROCK 775VM800 AND THERE ARE SOME THAT RUN WITH THE FOLLOWING: Gigabyte GA-945GZM-S2 (rev. 2.1) ,Gigabyte GA-965P-DS3 (rev. 3.3), Gigabyte ga-945GCM-s2c (rev 1.0).

I HAVE HAD SOME RETURNS FROM PEOPLE THAT BUY IT FOR OTHER BOARDS AND WE TELL PEOPLE THEY DON'T WORK ON OTHER BOARDS. THE REALITY IS I DON'T KNOW WHICH BOARDS WILL PICK THIS CPU UP. THEY HABE SAID THAT THE ABIT AND THE NVIDIA CHIPSET WORK WELL. i REALLY DO NOT NOW.

THIS CHIP IS AN OPEN CPU AND CAN BE OVERCLOCKED IF YOU CAN FIND THE APPROPRIATE BOARD. CONTACT THE PEOPLE ON MY FEEDBACK THAT FOUND THE BOARD YOU WILL FIND THAT THEY ARE OVERCLOCKERS. THIS CHIP IS ALSO A COLLECTABLE ITEM. IF YOU CAN SEE THEY HAVE VIRGIN TOPS. NOT A SCRATCH ON THEM.

What a croc

even on of the pictures shows a Xeon processr running at 1.4 Ghz

He even admits they are engineering samples - Twit...

Sounds like a red neck brown turtle pusher to me....

Avoid..

Not 100% true. I got a Pentium 4 EE 3.4GHz Northwood w/2MB cache for $150 bucks on Ebay and it has worked great for about 2 years. It also was a huge jump in performance from my P4 3.2GHz. As long as their rep is good there is usually no problem.

@ the OP, seems like it could be a steppung that was never released. Hard to tell without Intel verifying it. I would email Intel and see if they can tell you anything. Even send them the screenshot so they can look at it.

Good luck and hoipe everything works out though. Oh don't forget to CPU-Z it when you get it up and running, that is if it runs.
April 14, 2008 2:00:25 PM

Ya, that would be interesting to see what stepping it is, since L2 and M0 are the ones that are suppose to be out there. And if it was an ES, it should say "Confidential" as per mrmez/zpyrd mentioned.

Umm, 4 cores times 1.4 gig equals 5.6 gig, so he's close. :ange:

Well, I here McCain and George Jr have it all worked out.

McCain is going to nominate Condalesa Rice as VP.
After he Wins the election, C. Rice will resign as VP to become Prez of a Major Oil Company.

Jeb Bush Then becomes the New VP.
McCain then Retires so Jeb becomes Prez.

George Jr. Moves into the Guest Room and bosses his little Bro around like when they were kids.

I know it's true because I read it on Fudzilla someplace.

Hello Ed,

Thank you for contacting Intel(R) Technical Support.

I understand that you are looking for information on your Intel(R)
processor.

I have tried searching for the sSpec number SLA5F but we have no
matching information in our database about the processor you have. We could
try helping you out if you could provide us all the information located
on top of your processor:

1.
2.
3.
4.
5.
6.
7.

If you have any issues finding the processor markings please access the
following link:
http://www.intel.com/support/processors/sb/cs-025525.ht...

If you cannot find or read the markings, please provide us a
high-resolution picture of the top of the processor in order for us to find this
information.
April 14, 2008 7:57:11 PM

yeah, give them the wanted details. im looking forward for their reply regarding the chip u have.
