Intel Pentium Dual-Core E2140


Today we have the Intel Pentium Dual-Core E2140 on stage, yes – finally there’s a really affordable dual-core Intel processor that great for people on budget!


In the past I’ve always avoided Intel’s offerings as they cost at least RM 600 even for the lowest range of their better processors, however ever since the Allendale based Core2Duo E4xxx series was launched, Intel finally stepped into the ground of value computing with RM 400+ retail price. Intel stepped further into the value computing ground with the Intel Pentium Dual-Core E2140 with retail price of around RM 240, conquering AMD’s long-held budget ground. πŸ˜€

Please note that while the E2140 is based on the Allendale core just as the E4xxx series, it is NOT a Core2Duo processor. πŸ™‚ It is under Intel’s Pentium product range.

Today, I will compare the E2140 with the X2 3600+ (Windsor) – which is the lowest-end of the AMD’s Athlon64 X2 range of processors. The performance of the X2 3600+ Windsor version should not be that far off from the Brisbane based X2 3600+ which runs 100Mhz slower while having more Level-2 Cache.

Now, allow me to present to you the specifications of the contending processors for this review.

Model Intel Pentium Dual-Core E2140 AMD Athlon64 X2 3600+
Core Code Name Allendale Windsor
Fabrication Process 65nm 90nm
Voltage 1.162v ~ 1.312v 1.2v ~ 1.25v
TDP 65.0w 65.0w
Frequency 1600Mhz 2000Mhz
Level 1 Cache 32KB x 2 128KB x 2
Level 2 Cache 1MB 256KB x 2
Front Side Bus 800Mhz 200Mhz

Performance & Overclocking

Here are the contenders for this review

  • E2140 (1.6Ghz / 333.4Mhz RAM / 200Mhz bus / 800Mhz rated FSB)
  • E2140 Overclocked* (3.2Ghz / 400Mhz RAM / 400Mhz bus / 1600Mhz rated FSB)
  • X2 3600+ (2.0Ghz / 333.4Mhz RAM / 200Mhz bus / 1000 HT link)
  • X2 3600+ Overclocked* (2.5Ghz / 312.6Mhz RAM / 250Mhz bus / 1000 HT link)

*Overclocked = Will be abbreviated as OC

The Intel processor was paired with Biostar’s TP35D2-A7 while the AMD processor was paired with Biostar’s Tforce 550. Both setup use 2x 1GB Kingston Value RAM. The initial BIOS of the TP35D2-A7 was unfriendly for overclocking but their latest BIOS end of August was just great! πŸ˜€ The E2140 is now running at 3200Mhz!

The following are the results from the tests I’ve conducted


E2140 E2140 OC X2 3600+ X2 3600+ OC
4640 6690 4773 5231
* Higher the better

* Lower the better

As you can see from the results above, it’s performs well in comparison to the AMD counterpart. Realistically speaking, you can’t feel the difference between both processors BUT on benchmark, it’s clear who is the better processor.

Thermal Performance

  E2140 E2140 OC
Idle 23°C 35°C
Load 34°C 65°C

The stock heatsink performs admirably in cooling the E2140 on it’s default 1.6Ghz with only 34°C on 100% load. Load temperatures at 2.4Ghz the recorded only 51°C while at 3.2Ghz recorded about 65°C. Ambient temperature comes to about 25°C. I wouldn’t stick with the stock cooler for 100% overclock like what I managed but it shouldn’t be a problem for running at stock speed and lesser overclocking, just remember to monitor the temperature.

While the stock cooler performs well, I’m surprised that the mount on the heatsink was so strong that it bends the motherboard slightly (Refer to the 3rd picture below). Based on the recorded temperatures, it is advisable to run on a better 3rd party heatsink especially when doing extreme overclocking.



There’s nothing to complain about it. It’s perfect, sure it’s not the best performer in town but you can’t expect Quad-Core performance from a low-cost stripped-down processor, can you? You get you paid for and you’ll get even more out of it if you know what to do with it – this processor is absolutely a gem!

The strongest point of the E2140 would be it’s overclockability, it’s works well on stock and it performs very well especially when overclocked.

The only drawback with Intel setup is that good boards for Intel processors generally cost more than good boards for AMD processors which is the only reason why this processor is not featured in my PC Buying Guide πŸ™ .

  1. wooot!
    nice review of it, so…bila mau review quad core la? πŸ˜€

  2. Author

    Let’s hope someone provides me the processor. πŸ˜‰

  3. Still far away from Athlon X2 on performance & price?

  4. Author

    The thing is while the results are compared to X2 3600+ Windsor, recent price changes have placed the price X2 3800+ and X2 4000+ close to the E2140.

    So based on the results above and estimating the performance gain of X2 3800+ and X2 4000+ over the X2 3600+ (more Mhz and more L2 cache) – I’d say that the X2 should be better if you’re comparing at the same processor price level.

    For actual usage (not referring to benchmarks) then I doubt you could feel the difference. The E2140’s strongest point would be that it’s highly overclockable.

  5. what is the clock of X2 3600+ OC’ed?

  6. Author

    2.5Ghz. sorry I missed that one out cos the X2 3600+ OC benchies were added last minute. hehe.

  7. Hi there goldfries. nice review.
    but AFAIK, the fsb for AMD should be 200MHz (not 400MHz), so 200×10=2000MHz (2GHz).
    i think u done some typo error there.
    anyway thanks for the review..:)

  8. dude
    i oc the e2140 till 2.5ghz (fsb wall in mobo)
    but the temp still 42c
    thanx to the cheap CM xdream

  9. Hey GoldFries,

    Sorry for so many questions, but since some of my hardware is also in your reviews, so I have to ask about my Pentium Dual-Core E2140.

    I’m going to change motherboards, so of course I have to clean off the thermal compound of the original heatsink.

    But I run out of Coolermaster paste, and all I have is only that RM7 chapalang paste. Could it be sufficient or safe to use? How am I going to apply that chapalang paste since there’s no instructions? πŸ™‚

  10. Author

    Hehe. Not every paste needs instruction, it’s simple. Just place a bit right smack at the center of the processor. that’s it.

    And yes, those thermal paste are sufficient for use. Lesser thermal conductivity than those that cost more but nevertheless it still conducts. πŸ™‚

  11. Hey there,

    So I just need to put a small wad on the centre, and that’s it? No need to spread it at all? πŸ™‚

  12. Author

    Yeah. after you put the heatsink on it’ll spread anyway.

    If you spread it all over now, placing the heatsink might cause an overflow.

  13. Hey Goldfries,

    I intend to overclock my Pentium Dual-Core E2140, like yours, but with a Gigabyte 945GCMX-S2 board.

    However, not even an extra 5MHz increase of FSB is done at all, instead, after applying settings in BIOS it stops for a while, restarts, and bounces back to original settings.

    The thing is, is the board itself have a protection system? The system works fine enough after bouncing back to original settings. And, could my memory sticks, processor and the card hurt in that process? πŸ˜€

  14. Author

    Wait, you’re saying you attempted to OC with the board and it allowed you to change settings but in the end it just set itself back to default?

    Don’t worry about your memory, processor or cards. πŸ™‚ If it can’t boot, it’ll just go back to default. Usually the thing that hurts the system would be pumping of voltage.

  15. Yeah, the board allows OC, but then bounces back to original settings. Maybe the 945 boards hates overclocking, or the board isn’t that good in overclocking. πŸ˜€

    Maybe I’ll get a cheap T-Force board if it’s available and I will overclock my E2140 until it reaches ceiling… but I don’t have moolah for this. Never mind, maybe later. πŸ™‚

  16. Hey there,

    Could upgrading from an X2 3800+ / E2140 to any of the X2 5000+ worth the change, any boost in gaming framerates?

    Thinking of hosting online TF2 server, but not sure will my X2 3800+ will work or not… πŸ™‚

  17. Author

    Sorry, what’s TF2?

    As to upgrading of processor, it depends on what graphic card are you using. In the case where the processor is the bottleneck, then upgrade will see framerate boost.

  18. Huh?? I thought you know this already – Team Fortress II! That’s a hot game! Well, the framerates are very nice in my current processor, but if I’m hosting an internet server, I’m not pretty sure whether will it have improvements or not.

    As I’ve said already, I have a X1950Pro card, and I’m trying to future-proof the PC a little bit more. Not sure whether I will get a further push if I change to an X2 5000+. Crysis ran well in my current specs with medium settings anyway.

  19. Hey man,

    Back to the E2140 topic, with my BIOS finally updated for my Gigabyte 945GCMX-S2 board, I now finally get to overclock the whole thing.

    Currently now I’m typing in the E2140 @ 1.73 GHz. But my RAM speeds exceeding 667MHz, which is really in dangerous point! Btw, my PCIE/PCI freq is put to Async.

    Is your Kingston Value Ram a 667 or 800? πŸ™‚

  20. I have a 7300GT but wanna do an upgrade. But limited with budget. Will Radeon HD 2600 XT do me enough ?

  21. Author

    The_YongGrand at 1.73 isn’t much. Exceeding 667 is not dangerous IMO, looks like your FSB:RAM ratio is limiting you.

    My KVR is DDR2 667. it’s doing DDR2 800 only now but I’ve pushed it to DDR2 900+ speeds.

    Opteron, wrong section but I’ll answer you – HD2600XT is faster than the 7300GT.

  22. Hey, goldfries! Yeah, 1.73 is such a miserable overclock, because if I set it to 1.8 that system wouldn’t work at all, and bounced back to the original settings.

    So how can I modify the FSB:RAM ratio in my Gigabyte 945GCMX-S2 board? I couldn’t find any of them in the BIOS or its manual…

    And also, my RAM sticks are Mushkin ones. πŸ™‚

  23. Hey there,

    You are right, that’s the board limitation. Oh…crap, that board wouldn’t even work on any thing above 1.73GHz and not even any of the FSB ratios (i found it) are totally spared.

    Never mind about the board, as I have this for my extra ddr2 sticks and an extra pci-e video card to sit on it.

    Hmm… time to find something else to play… my X2 3800+… πŸ™‚

  24. Thanks goldfries. Sorry for posting in wrong section XD.

  25. the Super PI value in on 1M ?

  26. Author

    yes. value on 1M.

    I’ll amend the article.

  27. hey, gyes, i’ve got a problem with my Gigabyte GA-945GCMX-S2 in overclock: i can’t gain fsb speed more then 320mhz, and stability speed is nearly 300mhz. I’ve made a BSEL mod, but it didn’t help as much, as it could be. They say, that this mobo can easy get fsb 350… i assume that my problem is in using memory in singl chanle..

  28. Hi I am planing on buying a Gigabyte 945GCMX-S2
    its supposed to support FSB1066 (266×4)
    I’m going to try my Core2 E4400 2Ghz(10x 200)
    currently on a really cheap lame msi board that has no overclock.

    hope to get 2.66Ghz 10 (multiplier) x 266fsb =2.6Ghz
    also going to try a new(for me) CPU the E4500 2.2ghz 11 x 266 = 3GHz!
    hope it works.
    but The_YongGrand said : So how can I modify the FSB:RAM ratio in my G945GCMX-S2 board? I couldnÒ€ℒt find any of them in the BIOS or its manualÒ€¦ is there a way to increase the FSB ?

  29. Hyperion: Hey there,

    The 945GCMX-S2 has very limited overclocking ability. I can manage to only squeeze out a tiny amount even after a BIOS update. You might need to get a Biostar T-series board for the best bang of the buck overclocking board. πŸ™‚

    Or else, try getting the Gigabyte’s DS3 series – I heard that they works well with overclocking too! πŸ™‚

  30. Author

    Yup. some boards have very shallow or even no OCing features.

    If you intend to play with OCing, shell out a little bit more and you’ll eventually get more than that value’s worth of processor speed boost. πŸ™‚

  31. Hi guys, yes this is my first intel setup since the P3-500,(gone AMDfrom k7-800-2800+xp since) these Core2 are fantastic. so much less heat!!!
    put with a good card, thats the problem I’ve spent my money on a graphics card GF7950 512MB DDR3(double the power my last card GF7600GT) now the next board goes for 2X the price the Intel P35 Express Dragontail 1333FSB Motherboard. apparently,
    I’ve just downloaded the manual for the Gigabyte 945GCMX-S2 it says it can run at 1333fsb! pity if it doesn’t work I’ve already ordered it πŸ™ should arrive in a few days, I’ll post the results.

  32. Hyperion: Hi there. Glad you like the Pentium Dual-Core! It seems that the 945GCMX-S2 isn’t up to the overclocking task – it’s a basic, heavily stripped down board for budget gamers who don’t really care about overclocking.

    You has better try getting the Biostar TP35 or something – Mr. Fries has a cool review about it. That board is around RM350, but it’s a bang for the buck once you pump some more megahertz into it. πŸ™‚

    Another cheaper board will be Asrock’s Conroe1333 (the 1st version) but when you go for the FSB1333, the PCI-E frequency will be slightly increased, which will be quite unhealthy.

  33. OK I DID IT!!!!,
    I got 3GHZ clock speed 1066FSB working with the Gigabyte 945GCMX-S2. now running stable (99%just crashes on 1 program**more detail later) core 2 E4500 2.2ghz to 2.926GHz
    I had to adjust the RAM timing frequency multiplyer from 3.33 to 2.66 so the DDR667 ram is now running at (355mhz x 2)=710 on the default 3.33x multiplyer wouldnt run at 885 (too high) system wouldnt boot.
    ALSO NB set PCI-E freq mode to SYNC system refused to boot on ASYNC.also no voltage increase, and the best part Stock heatsink and fan! I used nano silver thermal compound and on standard settings got 25deg idle temp, with the 2.92 ghz overclock, its running at 37deg idle temp (still very good) and under load inc to 50 deg. board has a great Q flash BIOS -if it goes wrong when booting just hold del adjust save reboot, a real pleasure.

  34. Author

    Hehe. interesting. At least you get to enjoy the power now.

  35. yeah, I’m running FEAR [8800GTS Extreme]now 1024MAX everything (even soft shadows)16xAF, – 16x FSAA at 124fsp !!! runs stable with no crashes, – 575core, 1.8ghz ram
    the problem is the 1 program it crashes : is the Nvidia control panel with the 163 Nvidia drivers, that can control the GPU fan speed/advanced settings lol it seems ok if I don’t install that. It must be something to do with the PCI-E frequency being over-clocked too now ? any ideas?
    I’ve also played with it at 2.5Ghz and 2.6 but for some reason, dont know maybe ram -> bus speed ratio its the most stable at 2.92Ghz (266FBSx4=1066) and at the default (200×4=800)

  36. Author

    8800GTS on 1024. πŸ˜€ do you even need that power? πŸ˜›

  37. oh ya, lol, I was just benchmarking it against my previous cards
    on the Core 2E4400, 2Ghz with a nvidia 7600GT I got max 74fps no AA !!!! at 1024
    with soft shadows I got only 35fps now with 16X AA on the 8800 its nearly 100fps more a bit too much power for my 19″

  38. Author

    Hehe, framerate is something you can’t complain having more. πŸ˜€

  39. Hey there Goldfries,

    There’s a new model of Celeron which is called Celeron Dual-Core, which starts from E1200 (512K, 800, 1.6GHz). The only small difference in this processor is the cache half of that of the E2140.

    Any benchmarks of this? πŸ™‚

  40. Hey there,

    I will be getting a SLi board as a prize, and that board, Asus P5NSLi might be an overclocker as well.

    What type of a heatsink must I have for a successful, 1600MHz FSB overclock? Mine’s a E2140 too! πŸ˜€

  41. Just go for ximagtek S1283.. But depend on your ram also.. πŸ™‚
