all my other rails and volts are basically the same but for the vcore under speedfan and the asus utility

any suggestions?

Only .05V ?
This is referred to as vdroop and perfectly normal with this board

The only fix is a physical modification to the board - search for vdroop mod

Ok finally got around to testing my memory...2G of G.Skill HZ...
I've flashed the bios to 0401 from 0202 but I have one mem module that won't boot at stock volts...sooo boot with the other one, change volts to 2.085 put in other module boot from memtest 1.70 cd and lots of errors about 100 in 4 minutes....this doesn't look good to me...

or do I just throw some more volts at the ram....I haven't even tried ocing yet just changed the timings to 4,4,4,12

Window XP seems ok and the post ram test completes ok speedfan and PC wizard load and run fine....

or do I take the bloody RAM back....?

Edit:..just running memtest on the good module and no errors....looks like they go back...

Since the E4300 seems to usually peak out around 3.3ghz-3.4ghz, here's how you can get a performance boost: In the bios set the CPU multipler to "x8". Then select a QFSB from 1650 to 1696 (1700+ drops performance). Set your RAM speed at half of your selected QFSB and you'll get 1:1 memory timings and a slight overclock (assuming you have 800mhz ram). Don't count on using 1T memory timing in this QFSB range, memory timings at 2T will already be very tight (i.e. maybe your memory won't work here at 2T either!).

Now here's the kicker, with the E4300, SpeedFan and Coretemp currently UNDER REPORT the correct core temperature. Core temp is actually +15C higher! You can adjust that in the advanced configuration for SpeedFan. I'm currently running at 3.33ghz and showing 74C temperatures (that's with the +15C) when running ORTHOS. My system is stable, but nowI know why the CPU throttles intermitently (even though the throttle control is DISABLED in bios!). I had no idea before that it was so hot until I'd read at many places that the actualy temp is +15C higher!

Since a 100% CPU load is rare for me, I'm inclined to stay at my settings. If my CPU dies, I'll be happy to buy another too.

I'm sure this is old news but for those not sure about speedfan and just want to monitor volts and temps...our good friends at CPUID have PC wizard 2007 with support for the NV650 chipset....the temps are all labelled correctly so no need to change them....and there is enough extra info and benchies etc to warrant the download

App is incorrect, it reverses MAINBOARD and CPU temperatures. It also under reports E4300 temps by 15C like every other app. Overclock tab works for me though.

was the ram stable at auto detect settings at stock volts or did you change it to 4-4-4-12 right off the bat?

check its stability at 5-5-5-15 t2 at stock voltage then if that passes try bumping up the voltage to 2.172 for cas4 and/or switch out to the other ram slots - the yellow on my board are iffy but the black are just fine

I read all that confusion about offset temps not being recored correctly. The best way to tell is to feel the base of your HSF. If indeed your at 70c you will feel it. My temps are reporting in very low and I did just that and I also hooked up one of my senors to the base of the HSF and we close to what were being reported by speedfan and my HSF was not even warm to the touch ( close to ambient air temp ). I also think the problem lies with the 965 chipset which has had problems reporting Core temps correctly. I know that Asus has been working on bios updates to correct that.

What kind of performance boost? I am struggling to see how it would be much better than running at a slightly lower fsb and higher multiplier.

Will give it a try tonight and see, but with the p5n-e, every time I have set the multiplier to 8 I can not really get anything over an fsb of 1550 (or somewhere around there).

However, with multiplier at 9, I can sometimes still boot at fsb of 1600. Not brave enough to use th processor at 100% OC, especially since the voltage required to get there is insane...

 

[imported_Maz]

omg you fkn kidding me??? all my temps are off by 15c??? Why is the e4300 running so much more hotter than e6x's? I thought it was essentially the same cpu except that the missing 2mb of cache were actually physically removed (and virtualization tech)? Someone tell me this is a bad joke. My e4300 is rock solid at 3.3ghz and all my temps just happen to be at exactly what the should be when under full load (under 65c on cores and 47C+/- tcase)? I find this hard to believe that my proc is just down there cooking while e6x's sit pretty. If the temps were weird then I might believe it but they just happen to get reported at what all other conroe are at? come on...

When ''cpu throttles intermitently'' you're saying its slowing down and you're experiencing a degradation of performance? How do you know your cpu is throttling back? If this is true then there is no point in oc'ing this proc to 3+ghz... =(

 

[Core2]

The CPU does throttle back during idle periods. Open and run CPU-z ver 1.39 and you can see it. Put a load on the system and you'll see it throttle up to speed.

Nah the iffy module wouldn't post even with 5,5,5,15....needed 2.085v to boot...it was only after I raised the volts and loaded winXP that I upped the timings

I think I'll take em back

Yeah but i'm speaking to the statement that its throttling back because of extreme heat. I just cannot believe that the e4300 core0\1 are at 80C when speedfan says 65C. Whats with this +15C biz mr core2? I have a hard time believing this. Perhaps someone is confused about tcase and how tjunction is ~15C higher?

 

[darkshippo]

I agree with Core2 and Maz. I find it hard to believe that my core is 15C over because my heatsink is not even hot. Either my installation of the AC7 was bad.. I read that TAT on a P965 was reading the E4300 wrongly and that was 15C off.

 

[imported_Maz]

Yeah I wouldn't pay attention to this junk. Now if you were running at 3.1+ with 1.4+vcore and your full load temp for core0\1 is 40c or 45c then I'd say you're getting some wrong temps... And there are people out there getting these kinds of odd ball temps. But when your e4300 is acting like e6x c2d's in pretty much every possible way (because they kind of are e6x) then what in the hell would make someone think that temps are actually 15c higher... I personally can't find anything about this on the net.

You mind giving us some links where you got this information. The way you refer to 'core' makes me think that you're looking at your tcase temp and have been all along. Then you read the temp guide and found out about tjunction and are now proclaiming +15c on "core" to everyone. I can see someone on stock cooler getting tcase of like 60c and then freaking out when they find out cores are running at ~75c. If I'm wrong about you here and you do know what you're talking about then I'd say it doesn't apply to everyone. I've seen screenies where people had really high tcase while under orthos but their core0/1 temps weren't what they should/ought to be at; basically if you add about 15c to their core0/1 temps then it looked right. So maybe this IS happening somewhere to someone. But there is no way that my e4300 core0/1 is hitting 80c at full load at 3.3ghz.

So I'm gonna say proof or stfu. In a friendly way tho. =P

 

[uly166]

With my configuration on my E4300,356 x 9 and speedstep activated,cpuz says vcore 1.050 at 356x6,but asus probe,speedfan,everest...say 1´38 (1´375 in bios).

Why the vcore don´t slower with speedstep activated?

If you browse around here Correct Tjmax offset for E4300 you might find some answers.

apparently i'm not capable atm of understanding that forum... although I will give it another go when I'm off work. Care to explain something you know that I obviously don't?

Ok I have one problem with my over clock and MB in general. I can't get the system to boot the first time. From a cold boot it just hangs, I hit the reset button and it boots but with a error message the the boot was interrupted. Press F1 to continue.
From there it boots.
Any ideas?

¿have you all the washers in the screws of the motherboard?

 

[jkcheng122]

hi guys, i need some troubleshooting help.

i dunno if it's the video card problem or motherboard problem or something else altogether.

after i got the 8800gts, i upgraded to vista and installed 101.41 drivers. soon after, during wow, the game crashed and i got a bsod, i did not have time to read the screen b4 it reset my computer. after it was reset, it would never reach windows again. i would get bsod during the windows loading screen or at the end of it. i could not even boot off the vista cd as it would also go to bsod. i finally got around this by reformatting and reinstalling winxp thru booting off the winxp cd.

i should also note that i could not boot off the xp disc until i switched the video card to a older 6800gt i had laying around. and a funny thing is happening with the 6800 that i once again dunno if it's the vid card or the mobo. but from time to time while using the 6600 the screen would black out and flash constantly between windows and blacked out screen. after i got windows xp installed i went back to the 8800gts

so i went back to windows xp and a clean install, and things were going fine for about a week. earlier tonight the same thing happened again and i bsod'ed during WoW, and the system could no longer boot to windows w/o bsod'ing somewhere during the boot.

yes, i have tried booting to safe mode, to no avail. i've also tried booting off another video card, also won't work. i'm gonna try booting it again tomorrow, but i doubt it'll work.

question is, i can't isolate the problem, is it video card or motherboard?

From a post of an Intel tech, relayed form an engineer:
"Nor is there a register implemented in those processors that software can read to get the Tj value"

I take this to mean that there is no way of reading the T-junction temps in (4300) processors. I'd be interested to know how and where speedfan reads it if there's no register (sensor?) in place.

 

[Core2]

You have to keep browsing around in there
Link

Igor, an Intel engineer asked us to relay the following:

New CPUs based on Core? architecture have DTS (Digital Thermal Sensor). It can be read by extracting the 7-bit value from IA32_THERM_STATUS MSR
It is true. This public MSR 0x19C Bits [22:16] contains digital thermal Sensor temperature readout that is relative to Tjmax, Tjmax is processor specific.

However, there is a problem. That reading although available in °C is _relative_ to the Tjunction which is CPU specific. For some models it is 100°C for others it is 85°C
It is true, some are calibrated to 100C, some are calibrated to 85C. We should call that value as Tjmax for Conroe/Woodcrest/Clovertown instead of Tjunction.

I have heard that there is a MSR where you can read Tjunction. Unfortunately, that MSR is not documented. If I heard correctly it is a bit in MSR 0xEE.
It is correct, the Tjmax value, whether it is 85C or 100C, can be read from MSR 0xEE. This (85C or 100C) should be documented in the processor spec.

Also, to arrange to obtain non-public Intel(R) hardware documentation under NDA, you should work with your company's Intel rep if you have one (check with your purchasing department), or your company can contact an Intel(R) Authorized Distributor in your area and ask to work with a Field Application Engineer (FAE). If you have questions about this, contact us by email with details about your project and your job role and we'll see if we can help get you in touch with the right people.

It all boils down to if you have an all Intel System. If you do then possibly ( with Intel's software package ) you get accurate temps other wise their not releasing enough info to obtain it correctly. Asus probably has access to this info and that is where speedfan and others read to access their temps. Whether their 100% correct I don't know. Everyone else is using Intel's TAT, ( only usable on Intel chipsets and that was designed for the Mobile processor ) to compare their core temps and this is where all this confusion stems from. Of what I read the desktop and server processor are different and the values could be wrong or different. I have an 965 board and when I run TAT vs speedfan and coretemp the values are exactly the same. Other people with the same board different bios versions get different results. I would say because this is a Nvidia chipset there is no way to run Intel software to be sure. I would like to think that Asus has provided the right info that Probe, speedfan and coretemp are in the general area when releasing temps to the customer. What I have checked they seem close to me.

Any ideas?

What are you overclocked to? Put that in your sig. Save your setting in the OC profile under the tools section of the bios. Then Clear the CMOS. Load your settings and see if that helped
