Rate my e8400 OC :) please

[jerb]

Im @ 3.8 on my e8400, cpu voltage set in BIOS @ 1.2000 Fricken cpuz shows my voltage @ 1.136 lol and i do have all the thermal and speed step turned off everything on manual. Temps are @ 52c under p95 load (summer time with my slider open next to pc, temp outside 80f) p95 stable 8 hours.

This is on air cooling.

gimme your thoughts


~jerb


EDIT: Cpuz shows me @ 1.15 or 1.16 where as i set my voltage too 1.2 in bios.....

 

[Maziar]

Looks very fine to me 3.8 with that voltage is good
Congrats and enjoy

 

[shadowthor]

Looks good. Maybe you can go higher than 3.8ghz. What is your VID?

 

[BigBurn]

Im jealous I should have wait better revisions of the q6600 before buying it.. or baught a better mobo Stuck at 3Ghz

 

[Lupiron]

Woo, hoo! Do we have another with a low VID? Come on, 1.1000!

Big Burn, whats up? All q6600s reach 3.6!

Wanna run Core Temp, and list the VID?

[shadowthor]

Its a E8400 I believe not a Q6600 according to post.

 

[houstonserenity]

whats your memory strapping at?

 

[pcgamer12]

Why does Core Temp change VID?

 

[Lupiron]

Core Temp doesnt change VID, not the newer ones. It may be different from your settings.

@Shadowthor, The first comment was for the thread owner, his low VID, I hope is 1.1000! The other was directed at Bigburn, for the VID of his q6600 as well!

As you may or may not know, Q6600s don't go below 1.2000.

If i can manage, ill try to upload some screen shots later that include: cpuz, coretemp, hardware monitor, real temp and speedfan.

Speed fan always reports the lowest temp. It seems hardware monitor and core temp are exactly in sync.


Core Temp VID= 1.1750 it never changes, just lists the normal/stock i believe.

And HoustonSerenity, my memory is not strapped i dont think, but im not sure. Atm my memory is 4/4/4/12, 2.1v, 846 mhz, so its a tad OC'ed.

I'm gonna look for a new version, i downloaded mine about last week.

 

[pcgamer12]

Lol, i have latest, 0.99 and its glitching. VID goes from 1.1875v to 1.3250v. There are some other numbers in there too. Anyways my motherboard puts my e4600 stock at 1.3250v stock, is that my VID?

You should use Real Temp instead of those other programs for monitoring the temperature. Real Temp is the only program that is actually designed to measure the temp of the DTS on each core correctly. You'll see about a 10c difference between Real Temp and any other program such as Everest, Core Temp, or Speedfan. Real Temp is for 45nm/65nm, everything else is programmed for 65nm.

 

[pcgamer12]

I like Real Temp too.

I do use Real Temp, hence i said ill get a SS up at some point, the thing is that Real Temp for me at least always posts the lowest temps out of all the tools i use. Maybee it has to be configured, i have not yet tested the sensors or anything with it.


I just go by what reports the highest temp to me, just to be safe.


here is what i normally get @ Idle speeds: Real Temp= 34c CPUID hardware monitor= 44c Core Temp= 44c Speed Fan= 38c.

LOL, what do i believe in?

Doh I'm stupid, I guess I must have missed that when I read it since i saw 52c earlier thinking that was way too high for such low voltage and a 45nm chip. Thought you were getting that temp from something other than Real Temp. You may want to get a better cooler or something, 52c is kind of high for that clocking and voltage even if it is air cooled and in the summer. It was 32c here today and at load my E8400 @ 3.6ghz and 1.26v was only reaching 45c at full load. I'm using a ThermalRight Ultra 120 Extreme and OCZ Freeze TIM. And yes, I got a bad E8400 VID of 1.225v

Real Temp isn't reading low, everything else is just configured incorrectly to read the DTS on 45nm CPUs. Most programs use a Tj Max of 105c even for 45nm CPUs. 45nm CPUs should use a 95c Tj Max. For example here's what i have at idle:

31c + 64c Distance to Tj Max = 95c (real temp)
41c + 64c Distance to Tj Max = 105c (core temp, everest)

I thought you were referring to the post above you . Yea, 1.10 is good VID, should be able to get above 4ghz or more easily.

 

[Lupiron]

Hell yeah! That may be the lowest natural VID.

Since you are so interested in GTL and VTT and Vref junk, I am sure you noticed that VTT's natural setting is 1.2000 with 65 NM chips. So 1.2000 should be the lowest for those types. After all, if VTT were over VID, it would always get naturally over volted. Same effect by manually raising the VTT over VCore.

That's what I recommend that you not do it unless you have to. Of course there are safe limits. 1.4000 or under isn't much now a days, because as over clockers,. we are usually over that voltage in the Bios.

Also, VTT technical max is 1.5000. PLL starts at 1.5000 normally.

How nice of the numbers to line up.

But take a 45 NM chip, the natural VTT becomes 1.1000. So does that mean, like it does with the q6x00 series, that the lowest natural VID will be equal to VTT @ 1.1000?

It's shaping up to look that way! Only one guy close to it and near that low. 1.1125. That would be one over the lowest if all else holds true!

You'll see in some collection threads lower VIDs, but I bet it was random people replying with their speed stepped VID, since they are all old.

[Lupiron]

That's true. I wouldn't settle for anything else but at LEAST a 50% OC. So 4.5 Ghz. But the new guys don't wanna blow their computers up while trying, hehehe!

--Lupi

 

[hurbt]

haha i doubt ull blow anything up unless you take the HS off but you can mannage to cut the cpu's life in half haha

which is something I've been wondering about... if the life of my CPU is 300 years, who the hell cares if i cut it in half? But if it's only gonna live for 10 years, then yeah, I might care a little... then again, with a 4.5ghz cpu, i may be too distracted by all the pretty colors on my screen to care

In other words, what's the "normal" or manufacturer's stated life of a CPU?
