hi all overclockers, i am from Moldova!!!! i buy this chip and i run it at 3.6ghz on 1.275v with Kingmax PC8500 on Asus P5ql pro and it runs very very stable....30 idle and 52 full load with nice cooler asus v60, nice processor.

What a nice upgrade to my OC'ed E1400, Letting this one burn in a bit before I start to OC, idle temp is 33C, 47C load. Going to be at 3.4-3.6 by end of week (not looking for much). All in all chuffed. VEI index (nothing really to go by, but hey ho) is 5.3

These are great chips! Mine does 3.8ghz = 423x9 and its prime95 stable for 15hrs on the stock vcore.

This is with a Gigabyte p35 DS3 board and a cheap cpu cooler, temps never go over 59 degrees in prime95, E8400's must be up there with the best chips ever made.

Get one before they start disappearing from shelves.

Had this chip for about 10days now.

Running at 4Ghz stable on a Biostar Tpower I45.

Volts @ 1.288

TRUE Black, temps are 28-30C idle, and 50 Orthos...using 1 fan!

bought one of these a few weeks ago, arrived next day as expected from overclockers :) i got the E0 stepping, currently at 4.2 Ghz/1.300v stable, have been up to 4.8Ghz (on water) this is as far as i will go without increasing vcore beyond 1.45 as it can damage 45nm cpu's. even without OCing this processor is great, and will run very cool. excellent value for money

Come from an oc'ed athlon xp-m2500+ to this and the difference is astounding, don't even feel the need to overclock it's THAT fast!

Runs very cool aswell from what I can see, idles around 20c with stock cooling (speedstep enabled) and tops out at 48c load. The chip I recieved is also an E0 stepping.

Proper nice processor indeed!

This is my first C2D CPU and i am just amazed at the performance.

My last computer used an AMD 3800 X2 (939) and while it was a good fast computer, its hard to explain how much faster this CPU is.

It is still sitting stock, but after reading a lot of guides and reviews i will be overclocking it soon.

Upgraded from a 939 4200x2 4*512 ddr400 to e8400 asus p5q pro with 2*1g ozc 1066. i cant explain how much faster this goes at stock. my chip was a c0 stepping, ildes 40-45, load 51-55 on stock cooling.

i play mainly wow and this boosted my fps from 18-28 fps in shatt to 60fps allways (i play with v-sync) stays at 45fps in raids in combat & 60fps ooc

Bought one of these for initially HTPC use. (overkill I know but will be put to other uses in the futue)
In responce to the last post as regards 60 - 70c running temps, mine runs at 38-40C ( Freezer Pro 7)when playing BluRays and idels at around 30C.
My M.B. Asus P5K64 WS gave wildly false CPU temp readings for the E8400 and had to find other software for this task. (Real Temp did the trick, but there are others)
If anyones can recommend anything better for reading CPU temps I would be interested.

Reviewed by: Mr Smith

Awesome processor, great performance and great OC'ing capability! The one i recieved was of the older stepping so not as great an OC'er and still manages 4Ghz Stable on Air (A f7 pro) with 62 degrees load temp!
Buy now tbh.

Great chip, destroys everything. But runs very hot - Overclockers.co.uk seem to think 60-70c operating temps are normal, even when watercooled. E8400 gets 5 stars, service gets 1. Of course they wont print this.

I got this into my GA P35 DS3L Rev 2.0 runs perfect. On cold starting the fan doesn't seem to spin up at all until I reset it. I wam going to research this later to see whats happening.

I have to say this chip is by far the best overclocker since sliced bread.

Got it prime stable at 4.1Ghz with 1.3v through it. Temps never above 59c under Prime but when are you really gonna push your chip that far in the real world? So it's staying that speed. :)

Have not overclocked, and cant find a reason to, it plays on line games with ease, the jel that was on the cpu, i rubbed of and put on my own, kept the fan and temp.. not going above 37d.. my mother board supports the 1333fsb and i just amazed at the the way this runs without overclocking..

Amazing processor, only problem I had with buying this was that with the stock heat sink the temperatures got to over 100c. while i was only running it at 2 Ghz. Afer i replaced that junk intel heatsink with an Asus 79 Amazing heat sink my temperatures didn't go above 50. I am now over overclocked at 3.6 Ghz and loving it. Waiting on new ram to see of i can push this to 4 Ghz.

This processor is a MUST HAVE for any overclocker! Just make sure to have a good heat sink

Reviewed by: Martyn

For gaming, this is where it's at. Runs very fast and cool.

I was suprised how well the stock heat sinc cools this, but I think thats more because of the 45nm process, rather than the fan. Either way, you can get away with a bit of an OC on the stock fan. If your feeling a bit more flush, go for a nice aftermarket heat sinc and clock this thing into the 4s.

This things just works out of the box - it's blisteringly fast and the intel retail cooler is surprisingly good.

Overclocking is almost too easy. I've got mine running very happily at 3.6GHz (9x400) with the supplied HSF and stock voltage! It's so fast I haven't been bothered yet to see how far I can push it.

Quads are nice but for a lot of apps out there, a fast dual is the way to go. Buy this, you will be impressed!

Running this chip at 3.6ghz (9x400mhz FSB) at just 1.17 volts (1.2v in BIOS 1.17v in cpu-z and other monitoring software), haven't tried to run at even lower voltages yet as it's completely stable and runs pretty cool with the stock cooler.

Went to this from an AMD x2 3800+, my 3dmark06 score went from 7700 to 13100 with an 8800 GTS card.

Runs @4.0ghz with aftermarket cooler with total ease (vcore @ 1.37 on a P5K Pro). Should go much higher too I expect but happy enough at 4.0ghz. Buy this now - future proof your PSU and Board and wait 12 months for new generation of quads to come out supported by new quad applications, which are few on the ground at the mo.

Runs a lot cooler than my X2 4800 (39C idle, compared to 50C - standard Intel cooler on E8400; Freezer 64 on Athlon) and uses a lot less power (65w compared to 110w of the Athlon).

The whole system seems a lot smoother and I've not overclocked it yet.

I'm not that bothered about synthetic benchmark results, but in the real world I can say it performs very well.

.... the competition! This has to be one of the most overclockable, coolest running chips in the history of CPU's. Having upgraded from an e2160 to this, i can safely say that the difference in Crysis, TF2 and yes, even WoW, is absolutely amazing. Although it's at stock clocks with a IFX-14 + Xilence 120mm, it's running at 1.14v and 23-25c temps while "idle" (browsing net + disk error checking). Since Coretemp was reporting 52c idle, i assumed it was an error since the cooler wasn't even warm to touch. I then measured with Speedfan, lo and behold, 23c.

It doesn't seem to OC well, but that is probably being down to the mobo (Abit Fatal1ty FP-IN9 SLI) which is being replaced with a P5K-E Wifi next month (Someone at AOAForums managed to get 4.7Ghz on AIR!)

Don't wait for Quad-cores, they probably won't OC as high (It's a bandwidth thing ;) ). Buy one of these and enjoy it all now!

The OEM cooler with this is pretty pathetic buy an aftermarket one even if you do not plan to overclock !

My temp went from 55>35/36 with a cheap but very good Coolermaster HyperTX2 cooler.

My E8400 runs @ 3400mhz undervolted ! Yes it overclocks nicely and runs at a lower voltage than is recommended by Intel! If I up the speed to 3600mhz and knock the voltage back to stock it also rusn perfect !!

This CPU is simple Intels best value/performance to date and the overclockability is amazing. Mine should easy reach 4ghz with a little extra voltage and apparently this is not uncommon with these chips :D

If you are thinking about upgrading or purchasing one, i'd so go for it!!

Bought this chip about 4 weeks ago and it's running stable @ 3.68Ghz on Thermalright Ultima 90 HSF and getting idle of 23/19c and load of 48/46c after 12 hours of Prime 95.

One problem is finding temperature software that would accurately detect the core temps,but Core Temp program seems to do it right.
