Just got my x38-ds4 and e8400 in, downloading 45 vista updates :ROTF: ... i tried to run core temp but it says it need s a digitaly assigned driver, so maybe these updates will fix it?
it looks like bios is reporting the temp right for me, it has 24-26*c depending on what i set the fan speed to :shrug:
i'll post some results up in a bit
EDIT: i need help, all the temp monitoring programs still say they need a signed driver, what do i need to get?!
I think you need to turn off the need to have a signed drivers in Vista, I'm not sure there are signed drivers for the free download programs? I don't envy you trying to get your computer or the programs to work with Vista. I fought with Vista tooth and nail for several months, it was an extremely frustrating experience. I have gone back to XP Pro and haven't thought about my O/S since.
What VTT and CPU PLL are you guys using on any current overclocks your Orthos testing on?

Optional: CPU GTL: Auto
vtt : 1.2v

My stupid overclock
Evga 780i + E8400 Intel Pentium D Stock Heatsink.
8.5 mult x 500 FSB = 4250 Mhz. Mult using CPU/N2.
Core 0: 52 Celsius Core 1: 49 Celsius
1.408 V
Vid: 1.112
No way I am gonna stick with this clock 24/7, but I wanted to see what my chip could do.
1)I tried 1.33V for 4050 but it was no go
2)So i kept my 1.3V and lower to 3950. Prime still no go.
3)I did not went over 1.45V. And this voltage for 4.5GHz was only for one hour benching session.
4) I have the Maximus formula. I kept these settings in 24/7 and in benching
PLL was minimum to 1.5 but mobo overvolts to 1.6
FSB Termination to 1.2 but mobo undervolts to 1.1 because of Wolfdale. With
my E6750 previously 1.2 was 1.2 no undervolting. That means that Formula
has considered the right FSBTermination for Wofdales.
5)Since first day i was running at 1.3@4050 and after the benching session i had
the degrade.
Conclusion for me:all wolfdales that needs low voltage at start will degrade and reach those that are not good overclockers (e.g. 1.45V@4GHz) even at low voltages.Even if i have not raised the vcore to 1.45 i would still have the degrade in my opinion.
To sum up in order to bench at 4500@1.45V
CPU PLL: 1.50 ~ 1.6 monitor
FSBv/ VTT: 1.20 ~ 1.12 monitor
CPU GTL: 0.63x
NB GTL: 0.67x
Here is mine, FPO Q746A513.
It can do 8*480MHz (3.85GHz) @ 1.272V, tough on the screen its 1.288V but now at this moment I am running prime again with 1.272V...
Its a shame, I wasnt able to stabilize 8*500MHz, even with 1.368V under load, which is 1.384V idle, from BIOS 1.4250 coz' if vdrop...
I didnt want to push it more...
I also raised NB voltage to 1.55V, no help, SB to 1.60V no help...
WinXP loads up fine, AND IF CAN GET to desktop I can run Prmie95 or ORTHOS for gours, no error, no freeze, temp max 65 celsius, SEEMS fine...
BUT after a reboot, 3 out of 5 times when login screen comes up, i type my password, hit enter, and it stops there! Doesnt lock up, just slows down... it takes about 3 mins to get to desktop, but I can only see background, no start menu no icons...
Mouse still works, num-lock led active, so its not frozen but still, something wrong....
Could be this my mobo...? Cant handle 4GHz OR its my CPU...
As u can see it handles 8*480 absolutely stabel, 12+ prime95 small fft's test ran fine...
Any idea?:shakes:

On my Abit IP35 Pro to get RAM stable using 8x CPU multi at 1:1 512 FSB I had to up MCH voltage to 1.37, might even have to up it one step more, need to check. Wasn't any probs with 9x CPU multi using ram multiplier x1.2 with a lower FSB to get the RAM running at up to DDR2-1150 speeds without having to up the MCH voltage though.
Most of IP35Prot for 500 1:1@2x1GB fsb needed 1.41volt.
For 510 1.48volts for 526fsb 1.56 and so on.
With 5:6 divider 1.41 is needed for 450 fsb.
My giga board does the same. I think it's a way for the CPU to say "stop stop!"
I have a question. What is more important to performance? FSB and Rated FSB or The actual clock?
I'm wondering because I think I can go a lot further on my chip if I put my chip back at 9 mult and 1.45 vcore.
I have to say that even at 3Ghz this chip is much much better than the Pentium D 3.2 Ghz that it replaced.
On another note I found out something weird on my motherboard that lets me know if a clock works or not. When my comp starts, if it hitches and then continues during the mem test, then I know the overclock won't work.
Actual clock.

Where are you guys getting the e8500's can you post a link to an international shipper??
i think im in love, im running orthos at 1.28v @ 4.0ghz (only about 30mins in so far though) :D
My bios seems to be reporting the correct temps, they fluctuate perfectly. So it looks like im getting 43*c load and bout 25*c idle. I'll post some screen shots up in a bit
This should work but I haven't tested it as I don't have Vista personally.
start>run>cmd (command prompt)
then type "bcdedit /set loadoptions DISABLE_INTEGRITY_CHECKS"
If that doesn't work then this one might:
Bcdedit.exe /set nointegritychecks ON
Let me know if this works.
I don't think that "we" would regard it as the max. But through all the testing i have done, 1.15VTT works best for stability. By that i mean, in this thread and loads of other threads on the net we have had hundreds of peeps showing us hours and hours of small FFT Prime runs. That is easy to do at very silly clocks with these procs, and proves nothing. All, or nearly all, fall down of course because they fail large FFt's within seconds, which is why nearly nobody has posted large FFT runs. Getting high stable clocks out of these procs is all about GTL % and VTT as well as Vcore of course. These procs to me are all about proper clocking, you have to think about what you are doing, not just dial in a clock and forget it, because that won't work. The easy clocking days of C2D are over, if you want good clocks now, you have to really think about what you are doing and it's consequences, and then act on it.
After reading some posts about the potential for CPU degredation with higher vcore I am going to run the system at 1.360vcore for a few weeks doing the WCG thing and see if I can maintain stability after by testing with P95 again.
This is my 8+ hr P95 stability run. I will see if I can repeat it after a few weeks.
After a week with my 8400 @ 4.0ghz, 1.39v, i haven't seen any degradation as of yet.
someone have tested a e8400 with asus p5k vanilla? wich bios do you have used?
I *had* an Asus P5K Vanilla, and was running bios 0704 with my E8400. The board worked fine for a few days, then I started getting errors in windows and eventually after a normal windows reboot, the board refused to post and it never came back. If you have one I would recommend that you look at the new 0902 bios they recently posted, it says it includes support for new cpus.
Heres my 24/7 clocks
set to 1.28v in bios, i thought that wouldn't be anywere near enough :eek:
I only ran orthos for 2hours, good enough for me.
The "cpu" temp seems to be correct, its dead on with bios and appears to fluctuate correctly :shrug:

I was getting tired of my ridiculous temps (80+ on load) so this weekend I worked up the nerve to pull off my IHS. I have tons of experience popping open AMD chips, but learned that Intel chips are "soldered" on (and by soldered, I mean they use an adhesive thermal paste that melts at or under 100C). Did some research and found a logical removal technique involving a stove and pan. However, as I was cutting through the black silicone, the IHS just popped off on its own accord (scaring the $hit out of me in the process). Upon inspection, the die appeared intact despite the fact that I didn't even apply any heat.
However, when I put the delidded CPU back in my mobo, I was unable to get sufficient pressure between the cpu and my HS to get it to post (scaring the $hit out of me once again - thought for sure it was a goner). Tonight I finally found a copper shim that has allowed me to get enough pressure to at least boot up. My temperatures are predictably awful (die -> TIM -> copper shim -> TIM -> HS), but I am relieved to know that the chip is indeed alive.
Early next week, I will be getting some water cooling gear in. Included in that gear will be a spring mountable backplate (that didn't come out right, but you know what I mean). At that point, I will be able to properly mount my HS and will be able to provide an apples to apples temperature comparison before and after IHS removal. I will then post some water cooled results sometime the following week.
So I guess the moral of this story is that a) the IHS can be successfully removed, but b) I don't have any real comparative info as of yet. Feel free to ask me if you have questions regardng IHS removal.

Source two: freecableguy's technique for removing retention clamp to allow proper contact after IHS removal: http://www.thetechrepository.com/showthread.php?t=23
Source three: closeup of Wolfdale without IHS - note no SMD's to worry about, so removal is more or less worry free: http://en.expreview.com/?p=142
can you take some picture of the IHS being removed.

Would you guys think that it's silly to run 1.45v 24/7?
Up to you really. I'm currently Orthosing at 1.5v for about 2 hours. Will use this daily i guess as coretemp doesn't exceed 73C and Smartguardian (monitors from diode) stays at 65C.
http://ocidb.com/albums/userpics/101...thos2_20hr.JPG
I would not go above 1.365v for 24/7 use. That is the recommended maximum vCore that Intel advises, although their technical documents show 1.45v as the absolute maximum cpu voltage for the E8000.
Intel also recommends surprisingly low PLL and FSB Term voltages also, which many current motherboards do not even allow settings that low (despite claiming to be 45nm "ready"). But many of us happily exceed these voltages treating our Wolfdales just like we did the 65nm Conroes. I hope they hold up in the long run?
My setup is solid as a rock at 4.005GHz (445 x 9) with 1.365v. I have my ram at 5:6 (558 MHz) @ 2.15v; Cpu PLL@ 1.4v; NB @ 1.25v; FSB Term @ 1.20v, with a Performance Value of 6.
I did put 1.60v through the cpu to reach 4.6GHz, but I wouldn't recommend going that high except for short period testing...but to each their own!
Righto, I'll leave it at 1.39v @ 4.1 for now then

awesome:)
Finally got my 24/7 system configured.
For 4ghz, I was just putting thru too much voltage to be comfortable (1.376v idle, 1.344v load, CPU-z read). Well, that would have been okay, had it been stable, but I didn't want to put more volts through it to get it stable (maybe would have taken 1.4? We dunno yet if these chips can handle it!) I dropped it down to 1.328 (1.29v load, CPU-Z once again) and am happy with the overclock I currently have. I primed it for 23 hours... stable enough, I'm certain. :P I also dropped the VTT volts to the lowest setting, as you can see in Smartguardian. I tweaked the GTLs and am happy with the results. I now have a system I feel comfortable running 24/7 :)
E8400 Q746A377 VID 1.1125v
http://www.gvice.com/3.825ghz.jpg
Performance level 6, etc. Going to try to tweak for lower... we'll see. :)
Now that I finally got my setup running, I can join this discussion :D
Kinda forgot, but is it a big deal if I see a huge 10C difference between the cores? One's at 19 the other is at 28. I have a feeling the 19 is under-reporting, as that fluctuates between 3-4C's - even at idle, for no reason. OTOH, when applying a load, the increase in temperature is steady on the second core... so hopefully just bad sensors (and not bad thermal contact inside)?
about the lowest VID eh. When I use vista I got a VID of 0.975 when using XP: I got 1.05, this was the same with my Q6600, vista shows lower vid then XP does.. in my case.

vid depends on ACPi reading
so not true.
even coretemp is wrong by 0.1v..
best way to see vid is on the box itself.
hence ppl with 0.985 vid.. if its true their box will be showing 1.085v max..
AFAIK..
Both of my E8400's had one "jumpy" core, with the idle temps fluctuating up and down constantly. Other posters have noticed this also. Seems to be a normal anomoly with these Wolfdale's. My first E8400 was 17C/34C at idle, it's replacement is 38C/38C at idle with the exact same settings, but one core does flicker up and down from 38C to 32C, for no particular reason.Quote:
One's at 19 the other is at 28. I have a feeling the 19 is under-reporting, as that fluctuates between 3-4C's - even at idle, for no reason.
since ure using asus.. hmm i had a weird problem on the maximus and mem
this was a transition from e6850 to e8400 on bios 0907
i was fed up i flashed it to 0902.. and no probs.. and temps was more less accurate to my temp probe
then i reflash it to 0907..
now its working fine and the temps also differ.. weird aint it.
I thought core temps aren't tied into BIOS? Just frakin' inaccurate sensors. I suppose 28C's is more realistic anyway, seeing as I'm only on air. Not sure if it was this thread, but someone was using cascade (spelling?) and said that his core wouldn't even detect temperatures below 27C's - it just stopped there.
My e8400 just came in today! I will complete my new system once I am done with classes today. That includes the 5 hour class I have starting at 5:00pm :shakes:
PS: This is going to be my first PC that I built and my first CPU that I am going to overclock :up: (CANT WAIT!)

Think my retail will show up tomorrow. Hope my board like it :)
had a q750a e8400 and it needed 1.43 volts real to be orthos stable changed it for this q745a533 and this one is orthos stable so far at 1.272 volts, at 4050mhz
http://gbwatches.com/pics/orth.jpg
Yeah the power management being disabled or not can change the vid reading.
About the box though, I think all of the boxes all say 1.225v max. I have two of these e8400s and they both say the same max v on the box but core temp reads one at 1.100v and the other at 1.0875v.
I got my 8400 today with an abit IP35 dark raider motherboard.
=> this is my stepping : Q746A495
You guys think it's a good one?
GLENBOY, whats the longest you have ran orthos so far?
I need suggestions on this, i have my ram running at DDR2-890 / 5-5-5-18 / 2.1v (stock 1.9v), they feel pretty warm to the touch, on the edge of calling it hot. I bought a ram cooler but it doesn't fit. Should i lower it to 2.0v, do you think it would be stable, or do you think its fine as it is?

Q748A142
hiya thatguy its still going now whilst i'm typing, now 38 mins now, its weird i had an e8500 and that required low volts but ran hot, and this one is a little hot in my opinion considering its only 1.272 vcore whereas the q750 i had ran cool but required more volts , on a side note i think your more than safe with your ram volts
E8200 (Q745A705) @ 4.2Ghz (1.288v VCore) :up:
http://www.muenster.de/~e30pics/Bild...rime-02_kl.png
yes i think best batches are q743,745,746 the q750 i had was cool running but needed more voltage than everybody elses to be stable anyway
I kind of don't want to mess with removing my HS unless absolutely necessary seeing as how things are in a delicate way right now. I will snap some picks when I pull it apart next week. In the mean time, it looks very much like this http://en.expreview.com/?p=142, except without the crud on the CPU.
Nice vcore for 4050mhz Glen im glad you found yourself a good one m8 :up:

Heres a super pi run at 4.3 @ 1.38v (in bios). I think it still needed another small voltage bump, i was getting a few "this program is not responding"
Seems like it wants some vcore anything past 4.1

these X38 are like needles in a silo :)
some are crap some are good, dunno why, my sucks..
Got it stable at 4,3 now 1.45v, think 2hrs are enough..
4Ghz it will do at 1.25~ will repost more accuratly later.

If you want my opinion, DDR3 is so NOT WORTH IT! :(
have you played with ddr3? i got sloppy timings couse in non benching, i dont need to lower it...
and please do not try to tell me what's worth to me or not, my descission when i bought it.... and im happy with it... clocks well and benches better than ddr2.. so so tired of all people just complaining of the damn ddr3, JUST DONT BUY YOURSELF IT THEN, and those who want to can do it.......so you think all you stuff are nescessery? cmon , cut the crap, this is XS and no whining booth. let peps get what they want! and enjoy their results!
yes its weird i have tried 3 new e series cpus and they all seem to go to 4600 but no more some with lower voltage but after 510fsb they get unstable no matter what volts on nb or cpu
