most peeps agree for 24/7 stay below 1.45Vcore with decent water cooling on 45nm...
Like Leeghoofd said, 1.45v should be ok, but...
Intel specs are of 1.36v, so 1.45v will be 6% out of margin, so safe acceptable if it is a bios setting with vdroop present. Now, 1.45v is rather very high if you use a vdroop workaround in bios, since it will give you up to 1.55v "invisible" overshoot (14% out of intel specs, so like overshooting a 65nm chip with 14% of 1.5v = 1.71v :eek:). Overshooting will depend on your motherboard components quality, but it is not documented for any product existing yet. Only vdroop is implemented by manufactures to remain on safe side. Your 1.48v for a 45nm chips is considered too high if you enable vdroop mods. Without them, you're still at 9% out of spec, so really also on the extreme limit. You can test though, if you're lucky, your chip will survive some months, maybe more, maybe less, but it is risky.
Just a question....
What is the likelihood of being able to fit a 9800GX2 to the P5K-Premium with all six SATA slots occupied? No chance?
All SATA slots will be covered, at least the first 4 ones belonging to the intel SB. So, you'll loose at least two connectors. A workaround, that should be tested, is to use 4 angled 90°C connectors and force two of them a bit (the distal ones) to be covered by the two others (proximal connectors)
This possibility should be confirmed by owners of the card
Thanks for the reply, I expected it'd be a pain. Oh well new board time, but I have to say this P5K-P has been great.
Before change MB (really not worth it few months before nehalem when you see the performance of P35, and the GX2 adding SLI performance to intel chips), just unmount your GPU and try connecting 90°C cables to the SATA1 to 4 ports. If they can mount, than it will be no problem. Also, to mount a 27cm card, often the case will be the issue on most mid and full towers
Do a search for "left angle SATA cables". There are a number of sites in the US that sell them. They are the reverse of the standard 90 degree cable and will allow you to use the inner SATA ports. They can be plugged in and looped back to plug into the HD.
Make sure that they are a low profile design though; if they are too tall they will not allow you to plug the video card in.
hi guys, i just have a short question.
i believe i have a board with sata port problem.(sn: 77xxxxxx, and used to have lots of hard disk error in system viewer until i swtiched to raptor).
the questions is: will the bugged board work well with 2 raptors in intel matrix raid(raid 0+1)? now i have 1 raptor, everything is fine, but i am not sure if it will work in raid 0.
thank you
thanks for the fast reply....
i guess ill take the risky chance, see if it will work with no problem in raid... if not, i guess ill have to rma the board..i am just too lazy to take out all the waterblocks.
btw, if i rma the buggy board, and get a new one with no problem at all, do you think 2 wd6400aaks in matrix raid 0+1 will out perform 2 raptors in matrix 0+1? i have been read so many articles and benches showing the new wd 640g aaks has same or better performance than the raptors.
WD will win on some tests if I recall well, especially those with large files. On small files, the low latency of raptor will win. Performance/prise/silence/heat/capacity wise, the new WD clearly is the winner. Now, there are those new velociraptors, but on the ratio above, I doubt they win the WD unless some specific usage cases.
thank you so much jonny, i bought 2 6400aaks today, and they run very will without a single problem in raid 0+1.
heres a brief result:

is this performance considered good? or just normal...
i think this is not matrix raid tho, and i dont know how to set matrix up....gonna learn more from the net..
ill update more details tonight...
6400aaks really rocks
enable "write back cache" in the Intel Storage Manager....watch your burst rate get into the gbps range.
http://img519.imageshack.us/img519/691/burstitpb4.jpg
damn thats crazy burst rate, i did want to enable it in the device manager, but figured out i couldnt do it there....hehe. i am very new to raid...
just have a few more questions: after plug both 6400aaks, i hit ctrl+i into raid setting, i first create raid 0 with 16k strip, then raid 1(is this the right order?). after that, just normal windows installation, followed by intel matrix storage console. does this mean i am already using intel matrix raid?
also, i have done alot of research on the net about the strip size for raid0, but different people has different ideas about it. theres no "most common" or "best" stripe size?
You have to install the Intel Storage Manager, then you can enable write back. http://downloadcenter.intel.com/Prod...ProductID=2101
You are using matrix RAID 0/1. I tend to use a larger stripe on drives that have larger programs and files, like games. I think 64k is considered the norm.
new result with write back cache enabled:
http://img210.imageshack.us/img210/4800/hdraid0ia4.jpg
how come i have such a high cpu usage...
WOW!!!! Thanks for the tip mate. I gained an extra 100MB/sec average transfer speed after enabling, not to mention the burst rate :up:. I am using 4 x WD3200AAKS (B3) hdd's Raid 0, 64kb stripe size. See results below.

Also to the person who asked whether you can use all 6 SATA ports with a 9800GX2 installed. Yes it is possible but you will need 3x right angle sata cables & 3x left angle sata cables. I am currently using 5ports & have a 9800gx2. It was like trying to find a needle in a hay stack trying to get a left angle sata cable. I tried every shop near my house & was ready to order some from the US, I was lucky to find that these POS Acer PC's we repair at work actually used them so was able to steal a couple. :D
Your Raid0 is way too big. Best performance is achieved by using a thin slice at the beginning of the drive platter - set it up with about 80-100GB. If you havent read this thread already do so - http://www.ocforums.com/showthread.php?t=467848 you will be able to glean all the info you need to setup your drives in RAID 0/1 -or 5 or 10 if you have 4 to get the best out of them. The latter end of the thread is mainly around using 640's in raid0/1 - 5 -10 setup where they are getting silly performance. :up:
after installed some applications, max, min, average transfer rate in hd tune decreased about 20-40mb/s...
also, i found sometimes its laggy when reading from or writing to both volumes...
I have got two 160GBs and two 500GBs HDs, all of which are sata2. Any suggestions on how to set them up most effectively? Currenly they are in two pairs of Raid 0. but having a 1000gb Raid 0 volume kind of kills the point of it rite?
Help me out guys.
Depending on what you want to use the system for and exactly what your drives I could make numerous suggestions like setup MATRIX 0/1 on the 500's with RAID 0=100GB as these drives are going to be way faster than old 160s. That will give you max system performance and mirror your favourite data files. I would just use the 160s for further data storage backups for the critical files on the RAID1 , and data you dont care if you lose or not. For other options join enter the matrix thread http://www.ocforums.com/showthread.php?t=467848 and asking the question of Fritzman. These guys have been pushing the boundaries on the use of Matrix RAID and there isnt a lot they dont know.
Your missing the max performance benefits of RAID0/1 on 2 HDs with that setup and exposing yourself to data loss. Small RAID0 for max performance .e.g operating system but no resilience - uses stripping so total loss in the event of failure so you dont want data files in there. RAID 1 or better for mirroring but slower performance - e.g data file,music etc. FULL auto data recovery in the event of a disk fail. Whatever you setup you still neeed a further backup of your critical files to cover you from multiple disk fails - low risk but it happens and you cant retake digital photos. A nice large USB, SATA_E drive ,NAS server etc. This can also be used for an image backup of your RAID0 so you can recover operating system from BOOTCD with backup software - saves the reinstall from scratch.
Hey, My p5k-p has been having this weird problem, don't know if its common, lately, the onboard temp sensors seem to be malfunctioning, ie. after a coldboot, the on board temp sensors for the Processor's IHS temp and the motherboard temp work fine, they show the correct temps, then a few minutes later, they show weird readings. Asus PCProbe shows temps in the 200 ish for both, which we know is not possible, then if i do a reboot, the bios sensors show temp readings or -10 to -20C for both. really really strange, anyhow the only way i'm getting accurate temps is through Coretemp at the moment.
This problem common? any ideas? Thanks.
By the way, the problem was apparent since i went from Bios 0504 down to 0404, then reflashed to 0602 recently to accomodate my new chip.
Strange, as you mention it... I just noticed it today. Speedfan giving some subzero chilling temps, while, in the same time, PC Probe is telling me I'm approaching the sun. I didn't notice these since a while now. But, if I remeber well, I had those issues even on 0504, after some hours of benching ususallyat high temps on the sensors. After a reboot, everything back fine.
Sorry for image quality, but yes, PC Probe is reading 231°C
http://www.izipik.com/images/2008051...2-Untitled.jpg
http://www.izipik.com/images/2008051...9-Untitled.jpg
By the way, CPU sensor on bios 0612 is reproting bad reads too, alway reported temp above core temps, which is impossible
I'm used to these annoyances since my P5B Deluxe, nothing new with ASUS
does anybody know which version afudos allows to downgrade bios ( I want to test 404 , actually running 504 but weird issues with stability )
thanks
Why not try out Koda's tool here http://www.xtremesystems.org/forums/...d.php?t=186538 it worked quite well for me trying out the newer bios's. But I personally am happy with 0402.
haha i'm guessing that its a common issue then... o well, it was my mobo temps i was really worried about, as the Tracers used to push them to the 50s during activity, with the thing haywire, i have no idea how much i'm dealing with. thats why.
50°C for the MB is quiet high if out of benching. Even while venching extremely (Blend, large FFT, OCCT RAM) I try to keep it below 45°C, but it needs active cooling of RAM and NB. I never noticed any misfunction in MB sensor in ASUS board I had and between bios upgrades, unlike with CPU
yeah, i'm gonna try a format soon, could be a faulty driver somewhere.
anyhow, on a side note, i have 2 320G seagates set up in RAID 0, with 128kb stripe and no partition, giving it a total of about 600G, but i was reading on your previous discussion regarding burst speed rates and i was wondering, since i'm going to format, might as well redo the whole RAID volume.
what size would be ideal in this case of 2 x 320G? i was thinking of setting the smaller one up for the OS and the remaining space also as RAID 0 for etc data. that would be possible right? to have 2 seperate RAID 0 volumes?
thanks for the help.
i just set up a 100g raid0 for windows/games, and the rest for raid1. all my user profile and documents are moved to the raid1 volume.
i am still confusing if i want 2 raid 0 volume(1 for system, and another one for games, should i make them in ctrl+i page, as 2 different raid0 volume before install system, or just make 1 raid0 volume in ctrl+i, then partition it into 2 during windows install?
also, i had some strange problem with my raptor and ide drive. if i set the 6400aaks in raid mode in bios, the motherboard will hang on post after detecting usb devices. the only way i now know to get the raptor work is have the 2 6400aaks run in ide mode...and ide(pata)drive are not usable too. they couldnt be detected, and even in a external enclosure, they system couldnt find it..very wierd....do you guys think it might be a power supply issue?
thats good to know thanks

hey guys, what is the best bios to do a overclock in a E6750?
thx!
I run my 6750 at 3.6ghz 24/7-1.41vcore on the latest bios.
Sweet reliable and very oc'able board this.No complaints in all the time i've had it.
Regarding the RAID0+0, it is not possible on just 2 drives. But there is not reason why you couldn't set it up as a single RAID0 config, then set the partition size when setting up your OS, then in drive management, formating the left over partition and use that for your storage. I wouldn't do that personally, because of the volatile nature of RAID0.
If you go RAID0/1 then I would set 60g for the OS, and use the rest as RAID1 (you loose half of the remaining drive space do to mirroring, but if you loose a drive, then you only loose your OS, not your stuff on the RAID1 portion.
Haven't had problems with my Premium till last week.
The bios resets back to "default" settings when I shut it down overnight.
I redo my settings and they hold after reboot.
Changed out the cmos battery and flashed to 404 bios. Still no affect.
Got a rma # from asus.
check your cmos jumper is a good tight fit on 1/2 save and exit dont use f10 to save
Rich

dont use update with in windows very risky use ezflash using a flash drive. it shows bios version on boot if you watch or first page in bios main page
Rich
btw flashing in windows is very very risky
did they ever fixed the harddrive issue? Just wanted to know...not buying asus for a looooooong time.
Newer revisions are ok and some of the earlier ones do not seem affected.
Just noticed there is an 0707 bios on the asus site.Wonder whats changed.
i dont know but should be support for the new quads c1.s people been having temp problems readings

Hey, I was wondering if I could get some advice on getting my system up to par with some of the overclocking speeds that y'all have attained. My system is listed below in my signature, but for some reason I can't even get 400FSB to be really stable.
My temps at idle are usually around 45 and even at full load they never get past 60.
These are the settings that I used to boot at 400 FSB, but when I run OCCT it usually tends to fail the RAM test (the one designed to produce errors) in about 10 minutes.
FSB Strap:400MHZ
PCIE Frequency:100MHZ
VCORE:1.3V
DRAM Command Rate:2T
DRAM Timings:4-4-4-12 (Everything else on auto)
CPU and PCIE Spread Spectrum Disabled
CPU Voltage Reference:0.63X
NB Voltage Reference:0.67X
PLL Voltage:1.5V
DRAM Voltage:2.15V
FSB Termination:1.3V
NB:1.55V
SB:1.05V
Loadline Calibration:Enabled
I didn't want to go too much higher on any voltages that I didn't know how to really control, but I don't really understand why my stuff can't handle the clocks. I was thinking it might be because of the 8GB of ram, but I'm a lot lower than everyone else.
changing your fsb strap to 333 may help and maybe losen you ram timings
Rich
been looking myself no where to be found
Rich
yea i dont see any thing ftp://ftp.asus.com./pub/ASUS/mb/socket775/P5K_Premium/

Anyway I get a good deal to trade my P5K Dlx for a P5K premium... is the 0612 Bios compatible with wolfdale CPU's ? I will use Seagate HD's on the Premium so I hope to be spared of that known issue...
0612 works with wofedales yes and has some extra memory timing in bois. and yes your harddrives should work fine i havent try anything but raptors on mine sn. 79 rev. 2
Rich
i think the 0602 bios fixed most of the hard drive issues. i now use 2 wd6400aaks in matrix raid, works without any problem.
but if i put my raptor in, no matter on the red or black sata connector, it will hang after detecting usb devices, like keyboard. it will only post if i set ich9r in ide mode....
Latest one BIOS is 0612.
I think you're right,its for p5q,oops musta been half asleep or summat.
Anyone want to share BIOS settings for E8500 (or E8400) for this board? I'm having some stability issues that I didn't have with my 65nm CPU.
Thanks.
bump..
setting NB GTL to auto seemed to help.
Hi there.
I run my E3110 @ 4.2 Ghz (467 x 9) with everything except Vcore on AUTO on this board. Only 2 sticks of ram though.
Any instability below this FSB should be due to Vcore - nothing else (If your memory divider is set right).
Think this board can do FSB above 500 on AUTO.
Regards.
The thing with leaving everything on auto is, I have no way to know what settings the board will choose.. unless you know?
And could you clarify the statement "if your divider is set right"? I use two sticks as well and I'm positive the memory isn't holding me back. I can run it up to 1200 DDR2 speeds, it's the CPU that likes to flake out. For example Vista x64 seems to expose flaws moreso than XP 32 bit. Vista will give me MACHINE_CHECK_EXCEPTION BSOD on bootup a lot if my CPU is unstable, whereas XP will boot up fine and even run Orthos.
If your memory can do 600 FBS - you wont have any worries in that apartment.
My point in my earlier post was that you probably find the limit of your cpu leaving most of the bios setting on auto. Once this is established feel free to play with vtt, nb, cpu pll etc.
Hi
I have the following system:
Intel Core 2 Quad 9300 with Arctic Cooler Freezer 7 Pro
Asus P5K Premium (BIOS 0612) with stock cooling
2x2GB Corsair Dominator PC2-8500 DDR2 RAM with Dominator fan
Antec P182 case with 4xNoctua P12 fans
Current BIOS settings
FSB 440
Strap 333
(RAM effective 1057)
RAM 5-5-5-15 (subtimings on auto -3-52-6-3-3 I think) and 2N
Static disabled
Trans booster on enabled 3 (gived tRD of 6)
Volts - Core 1.2750 (with LLC enabled - gives 1.26 measured in Everest), FSB term 1.1, NB 1.25, SB 1.05, overcharge 0.7, PLL 1.5, DRAM 2.2, CPU GTL 0.61, NB GTL 0.67.
Both spectrums disabled.
System stable with OCCT RAM for 10h and Prime95 small FFT for 4h.
However when I try for 445 I have to increase NB to 1.55 (have tried inc FSB term instead but not stable), even if drop down RAM speed/relaxing timings or trans booster.
I note that some can get all the way to 475+ with NB at 1.25 so my questions are:
1) Is 1.55 NB safe with stock cooling in case as above (sys temp when stressing is about 45, thermistor from voltmeter on NB heatsink reads 49).
2) Is there anything else to tinker with to hit 450 (or higher) without increasing NB voltage.
Cheers,
Andy
ASUS P5K Premium BIOS build 0702

It's P5K Premium not P5K3 Premium.I flashed it.There are new options in the bios CPU Skew and NB Skew.
has anyone else tryed this bios out yet ?
Rich
Hi
Have tried. Still have OC failure at boot (same as jonny_ftm describes earlier) despite system being stable for hours with Prime95/OCCT. Have new BIOS skew options - tried changing from auto to CPU -300 / NB -100 and system became wouldn't post - so put back to auto until someone figures out whats good.
No other real difference noted.
Regards,
Andy
Is that BIOS official?
In my case, it was sorted by adjusting NB et RAM voltages. I no longer have those issues now.
Interestingly, I found a way to trigger that boot hang up when my OC is unstable. If I decrease NB or RAM volts, when I try to enter the bios, it hangs up, a reset is needed, than I can boot without even an OC error message sometimes. As soon as I adjust NB and RAM voltages, I'm again rock stable at boot/bios load.
Guess, every system has its specifics :rolleyes: The most important to consider, is that it's hard to 100% be sure ofan OC, it needs time...
Thanks. The only way I got mine stabe (despite inc NB volts and DRAM volts) was to change strap to 333 and hence DRAM speed from 1103 to 1057 - memory rated at 1066. Seems to be OK now on specs about 5 posts above.
I am interested in your thoughts on NB voltage. I can get to 440 FSB with 1.4 but any higher needs 1.55. I notice you get 475 at 1.25 but use aftermarket coolers - is there any voltage you would tweak to allow 450+ at 1.4 (I have tried most with no success).
Cheers
Andy
My E6750 does 450fsb @ 1.41vcore which is 3.6ghz.I am running it at 400 fsb(3.2ghz) at 1.35vcore atm.Temps are good at that.
I am thinking of getting a asus p5q-e soon though.
If I believe most what was said here and some other forums about the P5K, most boards will do +450 on lowest or 1.40v for the NB. Many others will need much more. Could depend on your particular setup (memory speed/timings, number of modules...) or the just the NB batch. Remember, the NB is like a CPU, some batches do overclock well, some others not. There are also often hidden revisions of the NB chipsets that intel often hides claiming them: minor or not to be considered bugs. The P965 was a an example...
Finally, motherboard manufactures often make hidden PCB revisions enhancing the overclock or fixing the bugs. The P5K premium is another good example with the SATA bug
Manufactures no longer note the boards/chips revisions just to be able to sell all their old stocks.

set CPU skew and NB skew AUTO,you'll increase CPU FSB without too much voltage
0612 Bios setting: 533*7.5 NB 1.70V CPU 1.40V
0702 Bios setting: 533*7.5 NB 1.25V CPU 1.28V
Thank you,ASUS!! my E8200's tempture lower from 70C+ to 60-!!!
My god, seems they messed with every thing :rofl: or you're missing it all...
How can you believe such a change? The NB, maybe, but the CPU change is a no no. Going from 1.4 vcore to 1.28 vcore for same OC has two explanations:
- you don't know what you are doing (LLC, stability testings...)
- they now overvolt everything like they often did
About the temperature readings, if these are CPU reading and not coretemp readings, than it is ASUS as we know it: 10°c difference whith every bios change
I'm waiting before I upgrade. I can't believe your comparision results
Certainly nothing that spectacular here. Stable at 443MHz with all volts on default other than CPU 1.2875 (for Q9300) and NB 1.4.
No real change in Everest benchmarks either.

Andy
