My temps are weird with this board as core 0 is 45 and core 1 is 36 idle. Under load with coretemp 0.96.1 it shows both core around 47-49 nothing higher. I did try to bench it at 4.5ghz successfully at 1.48 volts in bios and ran lower 10s in superpi test. I only orthos it for 10 min bc I did not want to put that much volts through it and not knowing if the temps reading are correct. I will wait to push it beyond 4.5ghz though, anyone else has luck with 4.5ghz.

i orthosed for over 1 hour at 4.5 with pc2-6400 ram with loose timings.

did you run dual prime/orthos, and what was your load temps after 10mins'?

 

[NdTRan]

after about 10 min I was in the low 50s on both core but nothing over 55 degrees. WHat voltage were you using at 4.5ghz for yours set up. Thanks

 

[Tempered81]

i believe i set 1.52 in bios and came to 1.44/1.42 cpuz / load. What vcore are you running, and 55 is hella cold for 4500mhz, i was touching 80C at load.

 

[Magusigne]

My First Overclock Guys.

1.18v

42C othos.

Set mine to 400FSB using all stock timings and voltages at auto.

E8400@3.6

Should I look into anything else. or do you guys think I'm safe with mostly stock settings at auto and altering my FSB

 

[NdTRan]

For 4.5ghz I was running at 1.4825volts, I did a vdroop mod on my mobo so barely have any vdrop if any on my evga 680. Yeah I figure 55 degrees is way too cool for 1.5v but its like less then 20 degrees here in NY last couple of days so could be why. Are you using vista or window xp, I am using vista. Are you measuring temps with coretemp, in my bios it only says 30-37 degrees.

 

[Tempered81]

a good idea is coretemp 96.1, everest, and if you have asusprobe or motherboard temp software... is to get readouts from all your software for your load temps... I've found reading everest and CT on my load temps was pretty much correct, however the Idle temps are always out of wack. One issue i had was my vid was sometimes reported differently during different boots in coretemp.

 

[NdTRan]

Is there a certain everest version you are using? ALso how is you idle temps, mine always starts at 45 and 36 on every boot no mattery the clock speed so far. Havent gotten any VID problems with mine.

 

[aussiestilgar]

My BIOS reads temps as low as 30c on boot, but once in windows Coretemp reads 40c+ idle, overclocked or not (even with speedstep enabled).

 

[Tempered81]

Im using the latest everest want to say it was 4.20.1257 or something along those lines. Yeah my idle temps were poor with a huge delta between cores, something very similar to yours, but i don't believe those are correct temps anyway, so no reason worrying over them. Just keep an eye on load temps. (i think load temps are read pretty close to actual for e8400s in coretemp and everest)

don't know the reason for the VID issue. buggy coretemp incompatible with wolfdales i guess.

There was a deal for the Zerotherm Nv120 for 33 after rebate. I'm at 4.05 and it runs at 38 load.

 

[NdTRan]

So i just orthos it at 1.30625 volts for an hr again using coretemp 0..96.1 and everest they both still reading the same temps, still nothing over 50 at 1.3 volts. I hope these temps reading are correct. Anyone else putting anything more then 1.48 volts thru their cpu? How high are you guys getting.

I had first tested it with just the CPU test in orthos and ran around 15 hrs at 1.26v so I then switched over to blend thinking I had the CPU volts correct. Orthos would then fail after about 20 mins just close on me...so I thought the ram wasn't taking the overclock..tried everything upin the ram volts, the NB volts and MCP volts wouldn't do anything..but everything ran fine on the comp..crysis, cod4 did some video encoding with no lockups, couldn't figure out what was wrong.

I then decided to up the voltage on the cpu to 1.3 which is like 1.35 in this bios..runs perfectly 24 hrs orthos stable. Anyone know why it would need that? it idles around 33-34 and at load its around 60-63 degrees..perfectly fine with those temps.. pretty sure this can oc way higher but i'm good with this for now.

EDIT: I set the bus to 450x9 now so the ram would run at 900 orthos stable for 12 hours so far and counting

IDk but same thing happened to me all works fine, similar temps to you

because the CPU test in orthos runs the equivalent of small FFT in prime95, which contrary to popular belief, although produces the most heat, is not the most stressful test.

large FFTs are more stressful. the reason that small FFTs produce more heat is because everything is stored in the cache, the parameters are passes within the registers, and cache is 60% of the surface area of the cpu! the actual calculations are not as stressful as large FFT, thats why an overclock that is 15 hours stable with small FFT might fail after a few minutes in large FFT.

small FFT is only good to find the peak temperature the cpu will reach, and it is very good to find out if the cpu will crap out because of temperature, but it is not a good indicator of general stability. but neither is large FFT, because large FFT will not heat up the cpu enough to cause thermal failure. thats why blend is an ideal test.

hope this makes you understand

ahh thanks man ya from your explanation I get why it crapped out on me..now at least I know why

 

[Tempered81]

yeah 1.26 vcore is a tad to low in some cases for a stable 4.0ghz. You still have plenty of headroom until 1.40 vcore (which is what many are calling the barrier for the safe-zone)

 

[Zapper48]

I downloaded the latest Speedfan Beta and it seems to be a few degrees lower compared
to Coretemp.So that's what I'm using.

 

[jhbball]

Just ordered one of these! I'll post my results soon.

When I first got the chip, I immediately bumped FSB to 400, memory 1:1@5-4-4-12 and ran prime95 blend for a day to check stability.
Since then, I have been running undervolted 3ghz@1.0375 for a month and finally got around to seeing if I could get up to 4ghz.

First, I did a day of memtest86 at 400fsb, 6:5 DDR2 speed to make sure my ram could run >900 Mhz. I had to adjust memory timings from 5-4-4-12 to 5-5-5-18 to get the computer to boot.

Then I did a day of folding+prime95 blend at 6x cpu, 450 fsb, 1:1 DDR2 to make sure the FSB could run >445 Mhz - I needed to bump my DDR2 voltage .1v to get this to run without errors all day. (HWMonitor reports the result of this as 1.92v, which is weird because "normal" ddr2 voltage gets reported as 1.87)

Finally, I tried testing with 9x cpu, 445 fsb, 1:1 DDR2.
I set the CPU voltage to 3.5 because the Intel processorfinder page shows a range of up to 1.3675 and I'm afraid to get too close to that.
Prime95 was only able to run for 6.5 hours before it aborted with an error.
Temperatures at load went up to 40 mb, 48 CPU and 46/50 on my cores.

I guess I'm done with that experiment, unless someone has a theory about how to get my 4ghz oc stable without raising cpu volts anymore.

Regardless, I just wanted to see whether it was possible and I'm not a fan of any overvolting, so I'm probably just going to stick with 3ghz/1.0375v from now on, unless I have a good reason to bump it to 3.6/1.225v for some task, which I don't really foresee. Stock voltage for my processor is 1.225.
