hey i got a question. got my new comp set up today finally

and i've downloaded cpu-z and noticed that my multiplier jumps and so does the core speed.

it goes from x6 to x10 and changes back and forth every second.

what's wrong here? i still haven t updated the bios and plan on doing so when i wake up so i can over clock.

http://aycu26.webshots.com/image/40105/ … 457_rs.jpg

nothing wrong there, it changes according to ur load when u r doing nothing on ur pc it will go to 6x200=1200, open a HD video or orthos u will see it jump to 10x200=2000

good luck OC this sweet processor, u can easily hit 10x350=3.5Ghz with stock voltages(1.35v)

The speeds jumping like that is called C1E.
It loweres your multiplier when idle. You can disable that option in your bios, and your cpu will always run at whatever speed you have set (2000 mhz in this case).

I personally leave it disabled on my rigs... I've seen no temp differences when overclocked usually.
I suppose it saves power, but I feel more comfortable having my cpu run constantly at the OC'd speed.

i just have one question. core temp reports my core temps as 42-44 Celsius idle but when i enter the bios the temps read 24-25 Celsius for each of the cores in their hardware sensors.

which one is more accurate? i m guessing the biios. but how could the temp be that much of a difference between the two?

@shamanaaa
both are correct

problem is they measure from different places on the processor. Coretemp communicates with an inside the processor sensor.

On the other hand, bios communicates with a sensor on the motherboard transmitting the heat from the processor's surface.

anyway, coretemp is becoming a new standard and i personally think it is more reliable.

EDITED:
here is a very silly diagram explaining what i said above, because i can't think of anything better right now than resting and making silly figures with my keyboard

Never trust what bios says.
NEVER!

You need one of this if you want to have the temp between CPU and cooler.

that means my temps are high

i think i m going to have to use arctic silver paste and remount the heatsink/cpu .... one question. how do i get the old stuff off?

some said alcohol with q-tips?

#878103 by unknown[138959] at 2008-01-03 20:49:05 (5 years ago) - [Report]

what are ideal temps for c2d processors?? is it worth putting as5 on there and removing the old preapplied paste? and will it make much of a difference.

here's my e2180 with 280 x 10 =2.8 ghz stock/ auto cpu voltage idle

with orthos load for just 3 min the temps sky rocket to 70 celsius :-O

now i have a few questions.

how come there's so many variations in temps? my bios also reports way lower temps then core temp. secondly why is it getting so hot if core temp is accurate? what's the maxium safe temp you guys strive for at max load for at least couple hours?

could my stock thermal paste play some role ? and how big of a difference would i notice with arctic silver?

and my fsb:ram ratio is set to 2:3... i couldn't where i could change it in bios unless im overlooking something.

so my most imporant question is what is the safe zone for temps, which temps are accurate (bios, tat, speedfan, or coretemp) , and why my temps would be that high and how much of a difference putting arctic silver in and remounting the cpu/heatsink.

lol another guy living in the Sahara!

Yes it's worth removing the heatsink to put AS5 on there... I would do it, anyway.

44C idle seems a bit hot.

[edit]
I see a problem.
Aren't the E2xxx chips 85 Tjunction? I think they are, which would mean CoreTemp is showing 15C too high. I'd have to check my E2160 rig to be sure. Its temps are much better than the temps you're getting... I wonder if it shows 85 TJunction?

I can't check it until Saturday, but Google might know if it should be 85 or 100.

well, i hit the wall :wall:

i posted before my OC results before but that turned out to be completely unstable

this pic for my e2140 8x200 OCed to 8x370 V=1.375v (stable with 80% OCing)
to OC it to 6x or 8x375 i had to set the V=1.4v (unstable)
@fsb above 380 with cpu:ram 1:1 it didnt boot at all no matter what (v=1.5v, all other v=+0.1)

This image has been resized, click here to view the full-sized image.

when orthos runs for 30 min and give me a stop error and turns the green part to red, what does that mean?

off-topic:
i had a lot of freezes/BSOD/autorestarts and i did:
- removed the pci cards (Graphics Card/TV-Tunner) and put them again
- got a new 650w PSU (has 2 big ass fans that keep the air flow through the whole case)
- new 2x1gb set of ram (kingstone value 667 could go @825 with stock voltage)
now the computer is stable and didnt hang up since, currently i'm not sure what was the problem ..??

looks like you hit the wall with this processor, i guess you should stick with 370FSB

couple of questions though?
- did it boot on any other thing other than 1:1?
- did you try settings you pci-e @ auto "told you the issue with this specific motherboard, remember?!"

it means stability stress testing failed due to miscalculation of 1 core or more. Try upping your cpu voltage a bit.

that probably means your MEMORY OR CPU OR BOTH are not stable@these speeds, did you try memtest before running into windows?!

when 2 rams where in dual ch it gave me some errors, when 1 ram NO errors .. weird, anyway i returned them and got new pair
i used "win memory diagnositcs boot cd" 1 loop takes about an hour so ran only 1 loop :-D

if u want to say something just say it :cool:

i wanted to test stability, as normaly i would be watching and recodrding a channel and want to see what on another one, this is while i'm browsing, emailing; i usually multi-multi-task

edit
how many channels do u usually watch at a time :-P

Normally while you multitask, do you run Orthos in the background for fun?
:giggle:

Do you even know what Orthos does?

yah, i like orthos colors, i always had a thing for its green color :-P

what i know is: it doesnt test graphics stabllity, the stuff that depends on GFX processor power like some video codecs and HD movies, also doesn't test peripherals(TV-Tunners) , right?

can you post a screenie of core temp under load for at least 15 min? i am wondering why i am getting high idle temps

edit: i oc'ed to 3ghz now and it is stable.. increased cpu voltage to 1.3525 or something near that...

fsb set to 300 and multiplier at x10.... ram timings at 5-5-5-15 and ram voltage at 2.15

i have a couple questions.

are the temps that i am running at safe? what would i have to do to increase my overclocking to the next level. i pushed to 330 fsb but it would'nt even boot into windows, just get the blue screen (ram letting me down?) at 320 and 310 the pc is unstable and cant fun orthos for more then 30 seconds before the red button appears and beeps.

any advice is appreciated.

coretemp reports 43-48 idle temps and 60-75 load temps currently at 300 fsb x10 =3 ghz

some screenies at idle, load, of some benchmarks etc.

and 3d mark score of 11323.. not bad improvement from 10081 ..oc'ed to 3ghz from 2.5 and 8800gt running at 738/950

@Shamanaaa
CoreTemp isnot working for me under vista64, but its temp is supposed to be speedfan+15
50--->65
52--->67
i also posted my coretemps before here (look up a couple of posts)

anyway, ur temps are a little bit high, i'm guessing u r using the stock fan, with the stock thermal paste

if u r having instability issues at higher clocks it is because the temps/ram, not the processor limit

i recommend that u get a good thermal paste, clean the thermal paste already their(on cpu/fan) with a tissue, and put some of the new paste(i'm using a paste that is white color not sure what brand)

btw: dont EVER set the voltage above 1.5, some people people on other forums say that they use 1.7v but intel think u should stick to 1.5 as max
http://processorfinder.intel.com/detail … Spec=SLA8Y

why is ur ram multiplier is 5:6 ??
set ur ram multiplier to the lowest 2.0 or 1:1 this should give u some extra cpu speed

edit:
@demagh
-the 650w PSU is "skyroad" it says on the box thqat it is silent cooling with temp sensors to adjust fan speed ... blah blah , but actally it sound like a bloody factory in my room (its a $8.5) :-/

i just wanted to make sure that my unstability isnt caused by the MB/CPU/Ram...etc, i will get a descent one soon

I got an old Dell that I want to overclock for fun. BIOS is shit as expected so was hoping for some software recommendations for overclocking. Motherboard is based off a i865g chipset with a 2.8c processor and some beautiful corsair xms3200xl that i want to put to good use.

So far I have ClockGen and the special i865/875 specific clocker. Are there any other programs that can let me tweak vcpu, vdimm, ram timings, pci bus etc?

Ta.

Hey guys, I checked my brother's E2160 this past weekend and it's Tjunction 85.

(CoreTemp reports TJunction 85 and his idle temps on both cores is 30C and 30C).

If it's truly 100 TJunction then I would have to add 15C to his temps to make 45C idle...?

[edit]
Found the old pic.
Here is his CoreTemp:

http://i18.tinypic.com/6xrdtol.png
* It was really cold in the house (About 70F) and this was right after PC was booted up. Idle temp normally around 30C.

Bios vcore is set to 1.325 (Not "Auto" )
