nice improvements on read and latency
585 is currently in progress, memory need to get stability >1150mhz
I always have the same problem, ram do not succeed be either with the default frequencies just overclock over 3000mhz. The last bios (f6h) does not improve the situation, he sets out for 1080 but the system is unstable under prime95 mt... :(
some advice?
Ps: sorry for my bad english... :p:
Use the provided bios template and show us your settings.Quote:

Primed for 30 minutes:), ran 3dmark06 got 12005 on a 8800gts 320 (my old card:p:) SuperPi32M:), but he rings today saying the o/c is lost again after cold boot.:(
So who can help me out with these cold boot bugs and why they happen, or maybe a solution?:shrug:
cheers:up:
I've been running with pretty low Ram sub volts 0.82v compared to 0.90v (normal per bios) at 1.80v base so 45.50% of vdimm however > 1150Mhz you need to start cranking it up to around the 50% mark. found +100ps clock skew on channel A & -100ps on B seems to help a bit.

time to start getting into overclockin again and what better way than one of these boards :D
i bought a couple of E8600 chips and from what Rex over at PCManiacs says they are going to be A599 chips that eva2000 has so they should be reasonably good
will do some testing with newer bioses in the next few days
looking forward to a challenge :D
Will give it a shot tomorrow ss thanks,Quote:

also this new bios is better....i was able to boot into memtest in dual channel dual core at 650MHz FSB.........
E8600@ 4800MHz

i've been using memtest loop#7 to fast track FSB Overclocking
Air cooled >> TTBigTyphoon:up:
I'm so glad your testing this mobo on AIR first dinos, everyone seems to go under H2O or LN2 straight away these days.
@eva2000 i've been watching your o/c's with great interest and i am very impressed with your e8600 voltages 4000mhz at 1.245v is unreal.:up:
Can you give me a rough idea of what voltages i should be using on a e8400 to get it stable at 4000mhz, i'm using vcore 1.4437 in bios which gives 1.408v in windows, but this seems a little high looking at your settings.:shrug:
At the moment i've scaled the o/c back to 8x500fsb and 2.4B 1200Mhz DDR2 using the stated vcore value above. This seems to have gotten rid of the cold boot bug i was experiencing at 7x575 2.0B 1200mhz DDR2.Quote:
[EDIT: ok i did some research over at this thread, i know der
and the avg vcore for 4Ghz for a 8400 is 1.30-1.35 so my settings are a tad high, even though i've seen 1 or 2 at 1.4v, what cpu volts and sub volts can someone recommend i try
keep in mind this is more a fly by the seat of your pants type o/c than a scientific one, 'cause i don't get much time to sit and tweak when i visit.]
yup test #7 very good FSB indicator :) looking forward to your VTT/VNB tips.Quote:

Funny 'cause we did about 5 cold reboots in a row with no probs when i was there, then pc shutdown overnight coldboots with o/c next day and day after, but today it cold boots and fails.:shrug:
Go into bios, F12 to load the profile, F10 save and exit, o/c boots no problems.
Anyone know what could be causing these cold boot blues?
I might try 2D instead of 2B divider and see how it likes it.
Hopefully I can reach 1333 DDR2 on the D strap with this board as I reached 1224mhz using the D strap on my trusty x38-dq6, plus mine where pc9200's, these are pc-9600's.
revert back to stock and see if it still does it
and then try small OCs first
A prize (or a curse) for the first person to get these settings stable.
666FSB x 6 = 3,996Mhz or x7 for 4,662Mhz
DDR2 2.0B x 666 = 1,333
Now there's an evil overclock for ya.
Be sure to have your system blessed before attempting this or you may need to find an exorcist in a hurry.
No problems at stock, it always boots first go on defaults but as this is an intermittent problem i have to blame the o/c settings as the ultimate 'causeQuote:

5. lower mch to 1.3
I just hope it's not his generic no-name 550W psu stuffing us around.
But definately not happy with cpu volts and subvolts as they are now.
Hey guys, I just got the DDR3 version and I'm getting some weird issues.
First, I start booting up at 10X400 at 1.2 volts. Then I reboot to bump it to 10X 410 and everything has reverted to stock settings including C1E/EIST ect. So I re enter all my voltages and I go to 420 and 430 and when I was going to go to 440 again it reverted stock settings. I was using the F2 BIOS that I got with the board so after some searching I first found this site, but it only had the DDR2 version.
http://i244.photobucket.com/albums/g...epol/gyg-1.jpg
So after much searching I finally found it here for the DDR3 version. So i update, but I'm still getting the same issue. I ran Orthos at 4.0 at a 1.224 vcore for 3 hours and when I rebooted it reverted to stock again. Sometimes when I reboot and enter the BIOS it says I got an overclocking failure when as far as I can tell I didn't have any issue. It happened when I was at 4.0 once and I'm almost positive nothing was wrong. Does it seem like I have a bad board? Has anyone else had any issues like this?
Also I'm having issues above 500FSB and I can't get anywhere near 5.0Ghz even at insane voltages like 1.8 and I'm on air. The vdrop and vdroop seem to be pretty big. I set it to 1.4 in BIOS @4.3 and it dropped down to 1.36 in CPUz and 1.328 under load. Does this seem excessive to you guys?

Sorry missed post below pic:shrug:
Then you have :lol:Quote:
the BIOS it says I got an overclocking failure when
sounds more like the usual thing your running with unstable ram , most likely to tight a tRD , especially if left on auto. what ddr3 voltage are you running ??
I'll give you an example. I ran 4.0Ghz @1.224 for 4 hours, did a little surfing afterwards, left the computer on all night and then rebooted, went into the BIOS to start bumping it up a little more and it said I had an overclocking failure. It's completely random like that.Quote:

Also no one mentioned if they thought that my vdrop/vdroop is too much.BIOS is set to 1.4, CPU says 1.36 in Windows and 1.328 under load. Doesn't that seem like an awful lot?

there's too much difference between these two Extreme boards,

as for your vdrop/vdroop
hicookie has posted a vdroop mod for the P45T-Extreme, it's in the linked thread
Hi all!
I recently bought the EP45 Extreme along with the E8600 CPU. I have serious problems with my overclock.
I cannot get 500FSB x 10 mult. The highest I have gone is 4.7GHz (523*9) after that the computer almost does not start (I can see the system restart several times even before reahing the BIOS screen). Nothing over 523FSB works... I tried 523*10 but no luck...
I have tried increasing the FSB, lower it, change the multipel, Vcore, MCH core and some other voltage tweaks in BIOS.
My system: EP45 Extreme with water cooling.
F7 bios. 4GB PC8500 (1066MHz)
E8600 CPU. (water cooled)
Nvidia 8800GTS (512mb) - also tested with ATI 3850.
I appreciate any help and hints!
i got a nice board on my hands here
just testing quick FSB and settings which were spotty on air cooling at 600+ FSB are flying on LN2
i am just doing 640MHz FSB dual core dual channel 8M Superpi
booted at 620>jumped to 630 and now 640
freaking sweet board this one
Dino
i have a bad cold boot bug >>>> -76C so i have to boot at 6GHz with these temps hahahahahah........while loading windows i hammer a lot of ln2 so it reached colder temps by the time windows starts
just doing a quick 32M Superpi at 6GHz
Sorry to revive the thread but I just got one of these to play around for a while (DDR2 version).
How much better those zillions power phases for CPU, NB and Ram work for the OC then the UD3P? I have some WR on the UD3P I hope I could go higher on the EXTREME :up:
it seems that its all board dependant
my Extreme boards are both much better than UD3P to be honest
Interesting Dinos, did all of your EXTREME perform the same?Quote:

nah the DDR2 had the best FSB
DDR3 next
UD3P was me was mediocre compared to how well some others faired :shrug:
@Jor3lBR
I think vtt limit on Extreme board is 1.8v as it on my T-Extreme. The DQ6 has higher around 1.9xx I think. Btw they all dont have LLC though..need some mod.
I think I got limited by vtt at 560x9 on Q9650. 1.78v-1.8v got freezing windows.:shrug:

I wonder what are the sweet spots for the References and the Quad 9650 in this board.
What settings you use with 1.20vtt for Cpu Ref, Cpu Ref 2 and Mch Ref?
I use at 1.2v vtt - cpu ref 1 : 0.82v - 0.865v ; cpu ref 2 : .85v - .875v ; mch ref : 0.775v - 0.805v.Quote:

With your GTL settings I can't even get it to post, the CPU Ref1, Ref 2, and MCH Ref are too high for me I think.
I then get it small FTTs stable for an entire day, next day same settings Core 2 fails with 0 minutes (Fatal Error 0.5 less then 0.4 error)... Always the same Core, same error. The other cores will run normally without any errors. I cannot duplicate stability on this board.
What skews your running? 1000 -1000 - 0 - 50?
Thanks!
i got success with extreme boards but firstly manually setting bios given GTL Ref in bios before i changed any settings ;) what that does is locks in a ratio for REF values once you start to pump voltsQuote:

I see Dinos.Quote:
Dinos22
Do you have the DMM measuring points for this board?
I do set the Cpu Refs and the MCH manually for 1.20vtt and then raise vtt.
Thing is on ET6 says it reads 1.20vtt on boot so my Refs are 0.760, 0.800 and 0.760 for 1.20vtt but it fails Core 1 in 0 minutes.
I played with those a lot but it starting to not make sense. I also tried Spardas Refs for 1.20vtt (cpu ref 1 : 0.82v - 0.865v ; cpu ref 2 : .85v - .875v ; mch ref : 0.775v - 0.805v) and no luck too.
Problem is that in the UD3P once I got the first day to figure these out it would play nicelly with any fsb, vtt and multi.
This board is giving me stability one day and then fails next day with same settings. I guess I have to play around these a little more.
:yepp: Different chip different settings. The basic settings probably the same though. I use 1000 -1000 - 0 - 0. idk my T-Extreme is just POS without the vdroop mod. Quite a lot of vdroop on quad. Set 1.2k on the vdroop mod fix the problem.
Yeah I know Sparda and you are right I'll get that done first, voltages fluctuation from 1.35-1.41 can't be good for Prime95 :up:Quote:

Now I have to raise FSB and lower Voltages (un-tweaked volts on Vnb, Vdimm):

My god guys, this board is a serious piece of equipment! I received it last weekend as a replacement for my Asus P5E dlx, as my E0 Q9550 was hitting an fsb wall at 470mhz on that board. From reading different sites, it seemed that the EP45-extreme and 45nm quads were made for eachother, and my initial results certainly confirm this:
http://i449.photobucket.com/albums/q...x85_stable.jpg
This is fully prime (blend and small FFTs) stable and nor 3dmark nor my games have shown any problems so far, so I am definitely flabbergasted by how easy it was to reach this! I didnt even touch skews or reference voltages, just set the voltages of my cpu from my old setup for 4Ghz, raised vNB to 1.36 and it's been running smoothly ever since. Benching my HD4850s in CF has been going really well too, hitting 14914 points in 3dmark vantage and 22423 points in '06! :yepp:
Thanks to the good info on this page, getting started on this board has been a breeze and I wanted to thank you guys for that! Now its time to press on to the magic 533, I can only dream of running this cpu at 4,5Ghz! :rocker:
damn guys
some serious FSB right there :up:
it does take a bit of tinkering and every board and CPU is a bit different
Yeah they are fun, since my old post I got the hang of the board and I could use the Q9650@4900Mhz for daily use on Domino water cooling system with some mods :D.
