Sempron 140 Unlocks to Athlon II X2

It has been done over and over again, and each time new AMD processors successfully unlock disabled cores (dubbed "defective"), it only makes us wonder if it is a deliberate attempt by the company to make buying its cheaper processors potentially rewarding. It has been discovered that AMD's recently announced Sempron 140 single-core processor can be transformed into a dual-core Athlon II X2 series processor with a simple, well-known trick. This comes as no surprise, as the "Sargas" core the processor is based on, is made by disabling one core on the Regor dual-core die.

The trick requires a motherboard with AMD SB710 or SB750 southbridge that supports the Advanced Clock Calibration feature. Not all motherboards, however, support this mod. By simply enabling the feature in the BIOS setup program, the system will be able to address both processor cores, with the complete feature-set of Athlon II X2. The staff behind the feat over at Thai techsite VModTech tested for the unlocked core's stability with much success. At 3.71 GHz (13.5 x 275 MHz @ 1.536 V), the processor stood SuperPi, WPrime, and WinRAR bandwidth tests. Validation can be found here. At around $40, here's the cheapest ticket to a dual-core processor that looks $80 Intel processors in the eye.

btarunrSteal the keys to RnD of AMD Sunnyvale at night. Cheap security won't look.
no dont do that. if you do we will be reading: Intel sabotaged AMD,... etc

Be glad when Intel unlocks my e6600 to a 8 core I7:laugh:

its utter stupidity selling single core cpus now when OSes support multi core cpus. i dont wanna see the performance of Vista or 7 on a single core cpu.

Actually, it's not that bad. Both Intel and AMD are churning out single core CPUs and pairing them with this type of software... HP sells the Neo with Vista and, hell, Sony ships the Atom with Vista as well! Are they great solutions? For a lot of purposes, no. However, when you need either cheap and/or low-power, they serve a very important roll in the market.

Besides, if they're just defective Regor cores, what the hell else are they gonna do with 'em? Better to make $40 than nothing at all.

if you multi task then a single core is not for you. Atoms are found in netbooks which are generally for web browsing and simple tasks. :D

People have multi-tasked for decades before dual-cores came to be. An internet machine doesn't need dual-core.

Vista and 7 are optimized for dual cores and can use them better then any older MS OS to date

i remember trying to browse the internet on a Celeon 1.7GHz, 128Mb ram with Firefox and i coudnt browse the internet on that thing. Firefox worked so slowly that you could take a 3minute brake and than come back and resume browsing. i know that the problem was that the pc had only 128Mb of ram but the pc could even handle browsing the net. that was in 2005 and FF ver 2 if i recall correctlly.

the OS was XP.

I just think it's funny some people will go buy
www.newegg.com/Product/Product.aspx?Item=N82E16819103698 this chip $40
and this board www.newegg.com/Product/Product.aspx?Item=N82E16813128397 $90
to try to get the same performance as
www.newegg.com/Product/Product.aspx?Item=N82E16819103688 this chip for $61
and this board www.newegg.com/Product/Product.aspx?Item=N82E16813130228 $80
$130 for a hope or $141 guaranteed lol my bad the second 2 have combo deal at $136 shipped

Exactly, I multi-task just fine on my single core Atom, my single core P4 based Celeron does the same...

128MB of RAM...and you think the single core processor is the problem? I have a 1GHz Pentium III with 256MB of RAM that browses the internet perfectly running XP...the machine originally came with 98SE!

a_umpjust curious, does ACC actually have any other purpose besides unlocking cores? i built my friend's PC with an Athlon II 250. the mobo is Biostar 790GX which has ACC as i looked at his bios yesterday. I thought regor was actually a true dual-core chip, it can't be unlocked to 3 or 4 cores can it?
ACC was originally introduced to aid Overclocking :D

that's nothing i have my PII 400MHz w/512MB of ram, and it runs XP like a champ :D

no. im saying that putting the cheapest stuff into pcs cripples them. i really dont get how a company sold a pc with 128mb ram and windows Xp on it :banghead:

if you would you build a pc with this Sempron and put it 512mb ram and then installed Vista on it. you would have the same effect that i saw on that Celeron.

no you wouldnt, my mums PC runs fine in windows 7 with 512MB of ram (and ran fine in vista with 1GB) on a slower celeron.


CPU means nothing! its all ram for vista and 7.

I installed fresh Vista Basic SP1 on a DELL Vorsto A860: 1Gb ram, T2410, X3100 GFX and it was extremly slow. i think Vista didnt like < 1GB of ram.


i forgot to turn off Vista's indexing function. that would maybe help. but i did turn everything else off. i turned off all the visual effects, also changed the UI to Windows Classic.
Vista index for the pc was 2.6-2.8.

vista runs like a dog for the first day or two on a fresh install, unless you disable system restore, indexing, and the hiberation file.

if you leave them be (and leave the system on for a while) it sorts itself out and works fine. How fast it sorts itself out is dependant on the HDD speed.

Shutting down UAC and Windows Defender also provides great boost in speed, as long as you don't need that extra security. :D

And for those guys with less than 1GB ram, why in the world you need windows for an internet machine? Just grab a copy of Ubuntu and install it. :respect:

after 3 days it was still slow.

i dindt install BitDefender on than pc as i found it was slowing the pc when more. so i installed Avast instead.

Do you actually know what Windows Defender is?
It is the anti-malware program from M$
Vista comes pre-install with it BTW.
Also it will be a great idea to upgrade to SP2.

Defender isnt an Antivirus only anti spyware.

Sp2 wasnt available in January 2009.

The procs are well priced regardless of the unlock.
Now the question is just why not get one? :p

You arguments up until now had nothing to do with the cheapest stuff going into PCs, it was about the usefulness of single core processors like this Sempron.

And while 512MB might be the cheapest, the difference between 512MB and 1GB is something like $4, so you would be an idiot to build a computer with only 512MB of RAM. I wouldn't do it regardless of what OS I was putting on the system. Hell, I make it a policy to never build a machine with less than 2GB actually... But now you are going on about RAM, in a thread about processors, where you started arguing that single core processors aren't good for people who "multitask" because "Vista and 7 are optimized for dual cores", then you start talking about RAM...

We all know if you stick an idioticly small amount of RAM in a machine, it will perform like crap. That has nothing to do with the topic, and certainly adds nothing to back up your original statements about single core processor being too weak for multi-tasking and modern OSes.

The fact of the matter is that single core processor are still good enough for probably 75% of computer users. Most people surf the internet, check email, use Office, listen to music, sometime rip a CD, burn CDs, watch videos/movies/DVDs and thats about it. And they usually are not doing all that at the same time. None of that, even when done together, requires anything more than a single core processor.

Now would I build a machine using this processor? Under the right circumstances, yes. But it would have to be an extreme budget situation, because with the E1500 only $15 more, and the x2 240 only $20 more, it would be hard not to take a step up to those.
