Post your E4300 Overclock!

[CompuTronix]

TAT is correct. Core Temp can not idle at 30c, is offset by -15c, and when corrected, will agree with TAT within ~2c. Core Temp and TAT measure the hottest part of the cores, while Probe II or SpeedFan, (not listed), measure the CPU Case temp, which is between the cores, and runs 15c cooler.

From the Guide:

Parameters

(A) Vcore should not exceed ~ 1.5v.

(B) Tcase Idle should be ~ 2 to 15c higher than Ambient.

(C) Tjunction Idle should be ~ 15 to 30c higher than Ambient.

(D) Tjunction should be ~ 15c higher than Tcase.

(E) Tcase Load should not exceed ~ 55c.

(F) Tjunction Load should not exceed ~ 70c.

Heat dissipated to the CPU integrated Heat Spreader, is in turn further diminished through contact with the CPU cooler, so even slightly above the heat sink / CPU interface, a temp sensor will indicate cooler.

Hope this helps.

Hey CT,
I think the problem people with the e4300 are having with your temp guide is that you seem to contradict yourself in regards to TAT. In order to be perfectly clear, do you believe that TAT reports the e4300 temps 15 degrees too high? Secondly, do you beleive CoreTemp shows the e4300 temp relatively accurately?
Thanks 8)

Well, the guide says TAT is off by 15 for 4300s, but CT says Core Temp is off by 15. What I really want is a temp tool that actually works, and doesn't pull numbers out of fresh air, or take readings from a dozen different places, or complicate the matter by having a bunch of weird undecipherable terms.

How hot is my processor right now? That's all I want, the truth, dammit. Even if I ain't gonna like it (I don't like that 71 @ 3Ghz TAT is giving me, for example, despite my three fans on my Infinity). And if it lets me keep a log, I might consider paypalling $6 or so.

 

[labortius]

Thanks Tacos, I have two actually on, 120mm, in the recommended position (pointing up pushing air to the PSU) and 120mm pushing air to a 65mm drawing air out (not actualy attached to the Infinity, to the case). My temps were this high even with just the one. It's a new system, and I've got other probs, like my 7900GTO running with half the performance it's supposed to. I don't want to hijack this thread, so I'd better start another. I'd certainly appreciate your wisdom though!

Exactly, I think Computronix isn't really trying to help in this regard. When people ask a question in laymans terms he gives a very technical answer. To try to simplify things a bit, TAT is reading the inside of the actual cores. The mobo readers(speedfan etc) are reading just outside the cores, but still inside of the ihs. Having an e4300 just complicates the matter because tat doesn't read it right. I just suggest using core temp. 90% of e4300 users across the web are using it so I would just go with the flow.

 

[CompuTronix]

Hey Pax2All, labortius, I_Love_Tacos, and unclepauly, let's back up here a minute...believe me, I feel your pain.

Until the manufacturers get their poop grouped, there's a complex mishmash of inaccuracies due to immature firmware and software support for CPU's, especially among 965 boards. So far, they've collectively done a poor job in supplying the end user, (you and me) with boards and software that report temps correctly and consistently...so we have a mess, and the community is confused. It's even worse over in the AMD dual core camp.

I appreciate everyone's suggestions, and as I'm continually striving to balance the Guide between simplicity, complexity, readability, and detail, I will be including some changes to reflect your ideas on the next edit, coming in the next few days. Understand that it's very challenging to write a Guide that covers all contingencies, especially since there are so many variables and combinations of inaccuracies.

Incidentally, please forgive me for the "technical answers" as I'm an engineer, and have been trained to be very specific, or "technical". Most often when users post temperature problems, they seek answers without provide complete information, and as I'm not intuitive, I avoid posting answers without asking for dedtails. Happens all the time in the Forums.

Now to take another look at the E4300 / TAT question, from the Guide:

Variables

The typical ~ 15c difference between the single Tcase temp, and the dual Tjunction temps can be erroneous due to calibration inaccuracies in chipsets, BIOS releases, driver versions, and motherboard utilities. Intel’s spec for thermal sensor accuracy is +/-1c, so temperatures can be quite accurate on hardware / firmware platforms free of manufacturer's deficiencies. Even false temperatures have offsets which can be analyzed, and when given correction factors, may still be reasonably accurate.

Troubleshooting

(B) E4300 CPU’s may report TAT temperatures offset by +15c and should be disregarded.

(C) 965 chipsets may report transposed Tcase and Tjunction temperatures with offsets of 15c.

(F) Core Temp shows Tjunction 85c. This field is Intel's Tj max spec, is info only, and does not change.

TAT reading +15c is not a certainty, especially when it's on a 965 board. Also consider the following:

Parameters

(B) Tcase Idle should be ~ 2 to 15c higher than Ambient.

(C) Tjunction Idle should be ~ 15 to 30c higher than Ambient.

(D) Tjunction should be ~ 15c higher than Tcase.

(E) Tcase Load should not exceed ~ 55c.

(F) Tjunction Load should not exceed ~ 70c.

The first rule of temps; no temps can be as low as ambient. If you think through the above items, you can see that Core Temp (Tjuntion) can not be near ambient, so under this circumstance, it's obvious that Core Temps is wrong, and TAT is correct. Having said this, I appreciate the notion that a more simplified and clear set of Parameters or "rules" would help users to understand how firmware and software inaccuracies can affect any temp readings.

Hope this helps.

See sig for OC, I'm still flapping big time about it though im worried it'l degrade the life of the system big time or just blow up. Can someone more tech savvy reassure me?

On that note though, is temp all you have to worry about? This is my first time overclocking in about 5 years, and it appears there's more than just upping a CPU multiplier now.

I read a few different forums, but this one appears to have the best info. All I'm wanting to do is boost my performance a bit, and end up kinda mid-range for now (don't want to burn out the components too fast). I've overclocked my e4300 from 1.8GHz to 3.0GHz, and although I bumped my CPU VTT to 1.35, CPU-Z says I'm running at 1.248. Is this anything to be concerned about?

I've got:
Intel e4300 (OC'ed to 3.0GHz @ CPU 9x 333)
ASUS P5N32-E SLI PLUS (OC'ed @ 1333MHz rated FSB)
2GB of Kingston CL4 DDR2-6400 (had to manually force to 800, mobo thought it was 667)
Enermax CXI-600B (600W PSU, with decent stats on all the rails)
7600 GT (crappy loaner video card, not overclocked in the least)

Like I said, I'm not looking to push to the limit, I just want to find a happy medium. Is there anything my dumb ass might be doing wrong?

Hello!

Could any1 put an eye on my post

Thanx!

 

[CompuTronix]

YelpingManCandy, try SpeedFan or you motherboard's monitoring utility to confirm Vcore. CPU-Z sometimes can misreport Vcore, so it's always advisable to get a second opinion from other software alternatives. Check out the following Sticky for information regarding temps and test programs:

I have a question about the lifespan of CPUs too.

Which will do it in faster? Upper vcore or upper fsb?

If voltages do it in the faster then granted I keep my mobo cool, should an E6300 run faster and longer at the same clock speed?

 

[Clob]

AFAIK: Upping the FSB or the Frequency does little to nothing to affect lifespan. Pushing the CPU past its spec volts can induce more wear and tear/electron migration in extreme cases.

 

[Pax2All]

Unless you are one of those people who can't stand fan noise, turn off smart fan when overclocking and you'll stay cooler.

 

[labortius]

Hey no need to apologize CT, we all realize you're trying to help! I just want a program that tells the truth 100% of the time!

 

[Gundam1s]

I currently have my E4300 overclocked to 3.0Ghz using 9X334 multiplier and FSB,
but the OC cannot pass prime95, I run the first small FFTs and In-place large FFTs is this the right test?

I've tried increasing the voltages for NB, FSB, and PCI-E but it still remains unstable.
I'm trying to keep my Vcore down because I get temps over
60C when running two prime 95. I am using the stock cooler so this lower Vcore
might be the problem, could this be true?

Also, the readings on the FSB is 1 mhz off, suppose to be 335, and the Vcore is
always lower on CPU-Z than in BIOS ~.025 lower.

Right now my specs are:
E4300@ 3Ghz 1.35V
G.Skill DDDR2 670 3-3-3-5 2.0V
Antec TruePower Trio 650W
8800GTS 320MB
Gigabyte DS3 Rev 3.3 F10 bios

 

[Viceras]

Ok is this strange; I'm running stable @ 3.0GHz (333x9) All I have changed is these vFSB +1, v(G)McH +1 Running Ram @Default 5 5 5 12 2.1v Rstio 1:1 (Ram @ 667) and left the vCore @ Normal 8O

It seems to be running fine but I have a few questions;

#1 - What if anything does (G)MCH do for performance
#2 - What would you tweak? With this set up (see sig) im only getting 5200Marks on 3DMark06 (it does say unsupported driver) it is Vista perhaps thats why. Im no expert but the score seemed low for this sys.

Any helpful comments?

Thanks :twisted:

 

[SuperFly03]

Alright let me break it down for ya.

E4300 @ 375x9 Stable (working on 380+, ICFX3200 has too many options)
ICFX3200
2GB G.Skill DDR2 1000 @ 503MHz
Voltages.... well I need to get a snap shot of the BIOS, but there are about 12 voltages, also had to tweak the FSB IO Strengths to get it stable beyond 355.

CPUz can't report voltages right

Idle @ 27c load at 50c

Initial stability started wavering around 2.85GHz.... I took it from there.

Well is the voltage in CPU-z lower when you are running dual Prime95 or when it's idle? If it is during Prime then that is what is called vdroop, and it isn't all that bad. However, You might try and arrange some air flow around the mosfets. My guess is your vcore is too low, but with the temps the way they are I would just chalk it up to a stable OC and roll on. I don't think you can get much more out of it unless you bring those temps down so you can increase the vcore. Invest in Tunic Tower *if you can* if not, 3GHz on stock cooler isn't bad.

Well, the guide says TAT is off by 15 for 4300s, but CT says Core Temp is off by 15. What I really want is a temp tool that actually works, and doesn't pull numbers out of fresh air, or take readings from a dozen different places, or complicate the matter by having a bunch of weird undecipherable terms.

How hot is my processor right now? That's all I want, the truth, dammit. Even if I ain't gonna like it (I don't like that 71 @ 3Ghz TAT is giving me, for example, despite my three fans on my Infinity).

OK, labortius, your wish has been granted. I've finished evaluating the newly released SpeedFan 4.32, and have updated the Guide (3/5/07)to include a new section regarding Offsets, which takes you to configuring SpeedFan 4.32 to correct for your offsets, so you can finally have one program that gives you accurate temps on all 3 C2D temp sensors.

Thanks CT! I note you took out the disclaimer (B) about 4300 may be -15 with TAT (that was causing mucho confusion!).

I guess my 65 of TAT is somethign to worrry about. Still, as you say, the CPU never gets used this much normally, so 46 is probably OK (CoreTemp 30/31 + 15).

 

[CompuTronix]

I guess my 65 of TAT is somethign to worrry about.

There's nothing wrong with 65c Tjunction:

Parameters

(F) Tcase Load should not exceed ~ 55c.

(G) Tjunction Load should not exceed ~ 70c.

...so 46 is probably OK (CoreTemp 30/31 + 15).

If you're refering to Tjunction Idle 46c, then that's quite normal.

Parameters

(B) Tjunction is always ~ 15c higher than Tcase.

(C) Tcase is always higher than Ambient.

(D) Tcase Idle should be ~ 2 to 15c higher than Ambient.

(E) Tjunction Idle should be ~ 15 to 30c higher than Ambient.

Hello folks,

I have been tinkering over the last few weeks since building i've also been posting alot to make sure the settings I have are good etc.. etc...

So here's the settings I used;

E4300 @ 333x9/2997MHz
DDR2 800 @ 4 4 4 12 2.1v
(G)MCH +1, FSB +1, DDR2 +3 vCore1.3500

I got absolutely nowhere until I upped the MCH +1 (Northbridge) But this board can take some punishment! 😉

Fully tested dual prime / memtest86+ / Orthos etc... etc.. :twisted: I have had it running higher but this seemed like a good spot to stop at, for now atleast.

EDIT: This chip is amazing; 40C Full torcher Load, 16 - 19C Idle Speedfan, Easytunes and Everest all confirm temps :twisted:
