£6400 2.1 or 2.050

[Bolerus]

I am looking at cpu-z and it is showing my new e6400 as 2.050 as opposed to 2.1.

Is that correct?

I know that is a tiny difference, but I just wanted to be sure I havent got a fualty one before I go any further.


I am starting to notice some differences between this cpu and my old northwood 2.8 (not so much that is faster, but that it doesent slow down in places the old one did, if that makes sense)

I am sure that a few people reading this (or maybe i am being arogant) remember my "no no dont overclock" opinion.

I have to admit, I am starting to wonder if I should Oc just a little bit (if I did I wouldnt go any higher than probably 2.8) but I want to be sure that I havent got a slightly dodgy cpu before i try to research how to overcloock, hence this post

An e6400 should be 2.13ghz. Anything else and something is wrong. Make sure you're using the latest cpu-z.

Also, a single core of your e6400 should be twice as fast as your northwood. However, youll only recognise this in benchmarks.

certainly not getting twice as fast

you will also note

Processor Frequency 2050 MHz
Bus Frequency 266 MHz
Memory 2047 MB

so that is showing as 2050 as well as cpu-z

northwoods results (with 1 gig of ddr 333 mem)

It is higher, but certainly not twice as fast, and the memmory has major contribution, with 1 gig in the e6400 I was getting 189 score
I arnt at home at the moment, when i get hom i will post up the cpu-z screen

sorry (noob alert) what is super pi?


I would imagine the northwood beats the conroe in some single thread test because the northwood is 2.8 ghz and the E6400 is 2.1 (or 2.05 as it seems to be runnign at) ghz

I am totally new to the new style of cpu ratings though

 

[Bolerus]

the cpu win is

i just noticed 8x multiplier? is that right?

and bus speed 252 ? that seems a stragne number (if that was 266 x 8 then it woudl be 2.128 which is more the expected number)


/boggle

 

[Bolerus]

so why are mine below that?


I know it is only a little bit below, but still it is below


what could be causing this, should I take the cpu back to overclockers and get them to test it?

arock 775 dual -vsta


i have looked in there and it is set to 266, and greyed out, so i couldnt choose it if i wanted to

 

[Bolerus]

well

I have just spoken to a guy at OCuk

He basically said he the chip will be fine it is something on the motherboard.


I had looked in there before but was happy to follow his advice and look again

went into bios and into advanced, the fsb was set to 266 as it shoudl be.

turned off, re-set the bios jumper to clear

started up, changed the memmory back to ddr400 (it sets to 333 as defualt)
set the overlcocking mode to one of the manual modes (there are 2 modes)

didnt change the fsb multipliyer thing, so that was still 266 as it said

booted machine

ran cpu-z

and now

corespeed :-- 2128.8 - 2129 (not quite the 2133 that it should be but close enough)
multipliyer x8.0
bus speed 266.1 (yay)
rated fsb 1064.5 (close enough)

I tried setting the options to manual earlier today, after my last post, but that made no difference.

I guess that is what I get for using a a cheap (and temproary ) mother board lol

Are those number im gettign now normal and expected, or should I be looking into other areas for the little extra im missing from the advertised ratings?

 

[Bolerus]

fixing that little problem gave me an extra 20 points,

i wasnt concerned so much abotuthe score, but more that it was clocking at 40 fsb lower than it was supposed to

 

[Bolerus]

sonny

open case

reset bios with jumper reset (right by the battery)

go into bios

go to advanced tab

change overcloking mode from auto to the first in the list that isnt auto

Dont change the numbers below

save it

start windows

incidently

I am runniing 2 gig of ddr 400

had a look at some benchmarks, and ddr2 seems to make very little differnce with this motherbaord, but i am only using it till i canb afford ddr2 and a better board

 

[Bolerus]

if you cant find the option, give me a shout and ill try talk you through it m8.


took me a few days and a call to ocuk to figure it out, but its such a simple thing its silly
