Stunning Performance, another great Intel CPU
operating system:
Windows XPFitted this processor to a Asus P5K motherboard. A simple bios update and the CPU was up and running. I saw a 500 point jump in my 3dmark06 score. Using a Sapphire 3870 and an e6750, I got a score of 10250. Using the e8400 I got 10770. Not much more expensive than the e6750, but gives a good leap in performance. I have had no problems with heat issues, using an Artic cooling freezer, the e8400 runs at a cool 26 Celsius.
what a cool chip
ive just slammed one of these babies into my asus maximus formula i38 motherboard, no problems what so ever cranked it up to 400 in the bios so it runs @ 3.6GHz (i will do the real overclocking later), very fast chip, Decided to run it on vista ultimate OS, with the coolmaster sphere it has a temp of just 17 degrees and ive been installing and downloading and playing music simultainisly for about 5 hours now and the temp has not moved, it hasnt gone above 20 degrees while playing crysis on max settings for an hour. good price very fast chip and i suspect gonna be able to handle a monster overclock too.
a hell of a lot of chip for a small price.
Max voltage 1.45v
operating system:
Windows VistaI have upgraded from an E4300 in an Asus P5b-deluxe 1226 Bios
needed.First day had running at 1.51v as shown in cpu-z;not a good idea! Apparently some boards overvolt and I found out some chips have degraded after a couple of days above 1.45v which is the intel maximum.so I reccomend checking voltages first in bios then cpu-z and set to the lowest voltage and definitely under 1.4v.Fsb termination voltage I think is max 1.1v for this chip but my board bios only goes to 1.2v?
Tjmax reads 105c on coretemp and 49c max on 4ghz 1.325v core volts with prime.95.Seems
some debate on temp readings with E8400.
Also does 3ghz at 1.1v ,1.06 with vdroop and temps max 38cwith prime running.
Probrably worth a gamble if you have E4x00 or lower.
Best dual core ever
Let me just put a few ppl straight, Intel stock coolers are fine for processors that run below 2ghz but anything above that and you need to put something decent on top of your chip to keep the temps normal. The E8400 should run between 26* and 34* in a temperate climate with a good heat sink fitted properly with good thermal compound. Even overclocked on air these processors should not go beyond the late 40`s; i have mine overclocked @4GHZ & my temps are 34* idle using a TRU heatsink.
Value to performance ratio for this CPU is 100% i dont think it will ever be beaten. To get its max potential it is made to be matched up with the P45 chip set and certain motherboards bring out the best in it.
All the hardware & lab test reviews of it are glowing and my praise for this processor is also glowing so if you have the budget and its a dual core that you want this is the chip, dont even think about it.
So i give it 5 stars without a second thought and the person who gave it 2 stars because he didnt have a decent heatsink to put on it: is that really fair? It is very misleading because ppl read these reviews to get some idea about the processor not your struggle with fitting it.
So: fantastic performance & speed, great value, great overclocker on air, defo worth 5 stars
LIke Yoda... small but powerful!
operating system:
Windows XPJust replaced an Athlon 64 4000+ with one of these; expected it to be a fair bit faster but the jump in performance is just astonishing! Plus it's quieter and runs a lot cooler.
Only 'gotcha' is that the CPU fan only starts turning once the BIOS has booted - thought I had a faulty one when I first fired it up!
bril cpu
operating system:
Windows XP5* cpu for price and quality.
for those with temp problems try realtemp, it reads my processor 25c core temperature oc'd to 3.8 on 1.35v.
core temp reads them at ~35.
although external of processor is read at -1 to -5.
Excellent value for money
operating system:
Windows XPThis is a superb CPU bearing in mind the sensible price.Very fast and runs at 36deg with standard cooler.Coupled with an Asus P5N-E SLI makes a great reliable system.
Highly recommended.
gr8
operating system:
Windows Vistareplaced an amd Athlon 64 4200+ with this, lightning speed difference... excellent.. I have to say after being an AMD head for many years, I'm very glad I went Intel this time... very fast and reliable processor! ( and good value in my opinion, comparable to amd finally)
fantastic overclocker
operating system:
Windows VistaBought an E8400 a few months back and have had no problems with it. Clocked to 4ghz nicely (1.26v after vdroop) using an ASUS wifi board and a zerotherm nirvana cooler (63degrees at 2 hours orthos). Highly recommended!!
great processor
operating system:
Windows Vistagreat processor easy set up,clocks well,runs at 30c at stock,i can see a big diffrence in my system,well worth the money,get 1
