Intel E8400 or E8500?

mudkip · Dec 14, 2008

Dear boys and girls,

For my new computer I'm looking for a dual core cpu but there's one problem. I don't know which to choose. The E8400 or E8500?
The E8400 is cheaper and overclocks well . The E8500 is a bit more expensive but has the same features (except the higher multiplier) . Which one to buy? Which CPU will overclock better in general? the E8400 or the E8500?

(Motherboard will be Gigabyte GA-EP45-DS3P , Mem : 4GB PC8500 corsair dominators, cooler : Scythe Mugen)

Hope to hear from you soon.

e8400 is my opinion coz its cheap

agreed. I own an 8500, the only difference is that it can take a slightly higher overclock, nothing more.
You should probably hold off for a little while for phenom2, or invest in i7.
AMD is getting really cocky lately, and a company doesnt do this unless for sure something is up.

go for the E8400 its a good chip and i've had no problems with it hitting 4.2Ghz with the right settings

LittleLizard · Dec 14, 2008

there are the same processor except for the 0.5 higher multi, go for e8400, u can get to 3.6 with stock cooling on stock voltages

Little difference in performance overclocking and price.
Toss a coin.

DonInKansas · Dec 14, 2008

Just make sure you're getting an E0 n the e8400; C0s require a bit more juice for similar clocks.

theposguy · Dec 14, 2008

Ill go with the E8400, Im very happy with my own

oli_ramsay · Dec 14, 2008

Get the e8400! Make sure it's the E0 stepping though.

mudkip · Dec 15, 2008

Hmmm ok . E8500 kost about 30 euro's more in the netherlands (30 euro's = 27GBP / $40 USD )
I will email the web shop about which stepping cpu they got

phanbuey · Dec 15, 2008

E-0 E8500... easier on the mobo, if your mobo isnt a great clocker (like mine), the extra bit of multiplier is worth the cash. Most of the E0 steppings will surpass the capabilities of cheaper Mobo's (dont know about p45) and some of the 45nm chips have FSB walls.

i.e. say on an e-0 you want 4.4 GHz...

so with a 9.5 multi thats roughly 463FSB - pretty high... but doable on most DS3's
with a 9 multi you need 488 FSB which is less likely to be stable... and might be too high of an FSB for the chip. Also higher FSB usually means hotter chip.

im still saying E8400 E0 NOT C0 .Im unlucky i got the c0 ,and GAp35 will do 4ghz easily

mudkip · Dec 15, 2008

I want to reach 4.2 / 4.4 Ghz . Should be possible with acceptable v.core but i'm afraid I'll get a bad batch. :laugh:

Can I ask you about your v.core. Which v.core did you use ,

infrared · Dec 15, 2008

4.25ghz is my 24/7 clock on my e8400, I'm using 1.35v set in bios (cpuz reads it as 1.32v after vdrop). I can push safely to 4.5ghz, but it requires a considerable voltage increase to 1.43v in bios. Fine for benching, but not worth the volts for 24/7 use.

Temps are awesome on this chip. 52c with P95 on the cpu test @ 4.25ghz on an AC Freezer 7 pro, which isn't exactly a high-end cooler these days!

nice thank you.
I'll definitely contact the web shop about the stepping. E0 :love:

And is your cpu and memory running 1:1 ?

hey my e8400 C0 is 3.82 atm with 1.37 idle and 1.34 load :S

As a comparison: i can only get the c0 8500 to 4.25 on 1.44 volts :banghead:

... @ 4.25 w/ 1.44 i get 55C in prime under water :banghead:

...

lol great chip...

And is your cpu and memory running 1:1 ?

Yep, memory at 1:1, but only because my motherboard craps out with ram speeds above 1000mhz with 4 dimms installed. I get better performance running a 5:6 divider (1200mhz 5-5-5-10). If your memory can handle it i'd do that. Edit - I think it depends on the chipset. Results may vary!

The chips are insane though, i was able to do a superpi run @ 5ghz on mine (on air remember!!). I think the chip had more in it too, but i didn't wanna push teh volts any more.

Edit: found the screenie!

Asylum · Dec 15, 2008

Get the E8500...i think all of those are EO and doesnt cost that much more!!
I got the E8400 CO when i order mine and cant get it stable past 4.05 ghz!!

phanbuey · Dec 15, 2008

Only e8600 are guaranteed e0... e8500 can go both ways :cool:

nice . I'm going to buy crucial or corsair dominators not sure. I red some articles about the dominators and they do'n tsee to overclock well..What happend to your crucia's btw?

infrared · Dec 15, 2008

my crucials? the single sided pc2-8500's? I think they're in my little brother's pc atm. Mine were able to do 1125mhz @ 2.2v 5-5-5-12, but Tigger's been able to get 1200 out of his crucials with 6-5-6-15 timings, so i might try that.

I've been looking at the G.skill Pi 8800 sticks! A lot of people have been able to get 1200 out of them with <2.0v
