Hi, you might want to buy a motherboard ASUS P8P67 PRO B3?
Vlas on the forum I read about problems with stability at idle, if the problem is to be solved in future versions of the bios? or immediately buy a home party?
from the top I'll add that I had previously GA-UD4 B3 has a lot of tension needed to stabilize the CPU, besides, all ok, the MSI GD65 was the problem with voltage control vdroop, but the performance was very good and very fast computer to work with a plate;)
thanks in advance
Some guys have problems with stability but not all of us. Some guys have also problems (reboots etc..) with the gigas.. ;) and i am not a asus fan boy. :D So it is your choice. I have no problems @idle and no probs@load (linx, prime etcc.. )

running 3 sticks ram?
I bet he used only 2 sticks.Run it in windows xp,you should chop off lots of seconds :)
you guys should take Asus p8p67 evo? I'm looking for motherboard to work, mostly scenes of 3d rendering and modeling, the platform must be 100% stable, and good to keep the processor at high clock speeds
alternatively, may be better to wait for the EVGA P67?
Im using my setup for 98% 3D work, and lots of rendering, so the P8P67 has been more then good :DQuote:

Tonight I tried to hit the 4Ghz starter overclock and no matter what I try once I have changed "AI Overclock Tuner" to manual win7 X64 hangs on the starting windows splash screen. Its not fully locked - as the windows logo is still "pulsing" - it just stays there indefinitely. It doesn't even matter if I change all the settings as described in the guide or no other setting except the Ai Overclock Tuner to manual the same thing always happens - once it's set to manual I'm stuck on the start screen.
As soon as I go back to default settings - win7 boots just fine.
Things I've tried:
- slowest mem settings
- higher mem voltage (1.65v)
- different memory (Gskill)
- 1/2/4 sticks of ram
- removing all but the OS drive from the machine
- OS drive on several different SATA connectors (both 3G and 6G)
- several different Core voltage settings up to 1.3v
Also as a note - I thought I would give the Asus OC tuner a go - it did it's thing and the same problem occurs when loading windows - it sticks on the Starting Windows screen. And again all is fine after restoring defaults.
Any help anyone may have would be greatly appreciated!
To try to pinpoint USB or device failure try other multipliers. Try to boot at x39, x38, 37, 36 and 35.
Also, are you setting OS multiplier control to disabled? (so that the software can not overclock in windows?) Try disabling the turbo options in the BIOS and just set an overriding multiplier directly (not sure of the options for that on an Asus board). I've seen someone having boot loops on a gigabyte board if they set both a multplier and a turbo multiplier at the same time.
Hi all, havent been here in a long time but after upgrading from me old trusty e8500 and Asus psq board to the much ballyhooed I5 2500k, a Sabretooth, and 8gigs of Corsair Vengeance 1600. Had some extra cash that me wife couldnt track so I went for it :D
Besides business which requires little horsepower, I'm an avid gamer -Arma2 to be exact, one of the most beastly demanding CPU game ever made. I was pumped that as soon as I made the switch my Arma2 benchmark program literally doubled it's FPS results -thats huge!
What little I ever once knew about overclocking has long since evaporated so Asus' new Bios/AI OC'er seemed right up my alley. Got the boot to 4.7 using the tool and just couldn't believe it was this easy. The last time I really dove into the OC world I remember lots of failed posts, seemingly dead new components, and plenty of cigarrete smoke and cussin.
Of course it was too good to be true once the BSOD starting occurring even when the PC was just idle. I tried a few manual settings and went down to 4.6/4.5 but Prime95 always kicked me into big blue.
I see that BSOD's are happening to quite a few here so maybe its not all on my end (hoping) but right now Im sitting at a modest 4.4 stable and loving the hell outta this upgrade :up:
nice to see you:p:Quote:

Looking at buying the P8p67, because I have heard they fixed the legacy PCI soundcard compatibility issue, does anyone know which bios has that fix?
Also for a mild turbo over clock to +4, would any of these BSOD affect me? no changing EIST, c states, or voltage.
Also those of you with USB issues, make sure you are installing an integrated Win7x64 SP1, the SP1 upgrade download has a USB bug that causes a lot of problems that haven't been resolved, there is a manual workaround at MDL.
Just RMA the CPU to Intel for a replacement.Quote:

Annoying since in real use the vcore max will be the linx one.
last week I bought asus p8p67 pro but after 3 days usage suddenly dead mobo .......... and surprise accompanied with the death of 2600k: (
No reason why?
How do you know the CPU is dead? Was it tested in another system?
Wouldnt the question be "How do you know the board was dead?"Quote:

reading your opinions, I found itis not worth it buying the series motherboards p8p67 ...
cheap and good boards fall out in reviews, and users are dying like flies, these motherboards:)
I had the first gen p67pro and the b3 after newegg sent me a b3 rev and they both had ZERO stapility issues.Fot the people that just got these boards becarefull with the current % and the load line,if you set it to 120% and have your defualt at 1.45 volts it will spike 1.6 volts to your chip once you put load on it.
start with low settings.You can fry a chip with ease if your dont know how this board works with load.
I also noticed on my new b3 board that it over volts higher than my rev 1 with the same voltage settings.
once you learn these boards you can have a perfect 24/7 setup that runs cold and effiecient.I have mine setup for 4.7ghz 24/7 with closed stock cooled case and it idles at under 1v with no stability isshues with 4 sticks of ram.Iv tried my setup on 2 p67pro boards and they both worked just as good with the only excletion was the b3 needed less volts to load the same(it would over volt a little higher)
I think these boards are great!!!

Are those Corsair's the C8 or C9 kits? I'm running C8 1T @ 1600Mhz - so that might be the 0.2% :D

I see an old bios, but aside from that pretty good...
I'm back though. I'm trying to use a USB cdrom drive that I've always used with this board... In every single one of the USB plugs on the backplate, I get a POST code error 64 every single time, but when I plug the USB cdrom drive out, the POST continues just fine. What gives? I literally used this drive for an OS install yesterday.

I think even the ASUS OC tool can do better, currently at 4.6Ghz 1.32Vcore rockstable with speedsteps enabled...(2600K on Pro board) Most boards OC the same ( for daily usage ) as the limiting factor is usually the CPU and it's cooling, not the board...
Well I don't know exactly what the differences from 1305 to the latest bios are, but typically, newer bios fix the bugs from the previous and can help with stability/overclocking.Quote:

Why can I no longer find the option to increase PCIe MHZ in the bios anymore? I could have sworn it was an option in older bioses. Now I can't seem to find it anywhere.
Well I updated bios and started having boot problems... wouldn't post, whereas the old bios would with the same settings plus now I keep getting pop ups from ASUS control that my vcore is running at like 1.56.. that definitely ain't the case.Quote:

Hello
I'm Spanish sorry by my bad English.
Las week I buy an ASUS P8P67 Motheboard and a 2600K. I tried to OC my system and always in Prime95 (64 bits) system freeze at 3 hours. I clear cmos and load optimized defaults and have same problem. I put memory timmings at reference (9 9 9 28 2T), vdimm at 1,5 and vcore at 1,2v, 1,3v, 1,35v... and same problem.
I have G.Skill Ripjaws X DDR3 1600 PC3-12800 8GB 2x4GB CL9 and I am thinking that the problem is memory.
Can you help me ?
Have you tested your RAM with memtest86+ ?
Are you Prime stable at stock / default settings with no overclock?
Hey anyone not going to RMA there board? Mine has been working so well for me.
I had some trouble the last couple of weeks, getting "Display driver stopped responding" etc. I tried everything, new RAM, new motherboard, different gfx, new PSU... nothing worked. Today I decided to buy a new CPU and now it works! Turns out the IMC or something crapped out on me after my benchmark 16gb @ 2133MHz :)
I'm running 1503 now which is what I got from ASUS.. can't seem to find 1505 anywhere though?Quote:

That's when everything was fine.. I need more Vcore now than I do with the older BIOS.
Anyone have weird things going on with the offset for the vcore? On idle the Asus software and CPu-Z tells me that the vcore is 1.46v but when I use the Intel Burn test both programs report that the vcore is 1.41v and is totally stable. Am I doing something here that i'm not suppose to?

It might have solved a problem for you, but maybe the problem also lies else where. Disabling C-states might have cured it, but maybe there was another way to cure it.. Say something related to driver or gfx..
Do you by chance have an AMD gfx?
I've run Nvidia and Amd graphics on my P8P67 Deluxe and had no issues at all with either.
I also get the "display driver stopped responding" error from time to time.
I have C3 and C6 disabled as well as speed step. My CPU runs @ 4.8ghz ALWAYS.
Haven't tried to fix it yet...just waiting for it to get worse...
Thats sad to hear, yes, i have hd 6950. But i have Sabertooth p67, Asus said they disabled c3,c6 by default (auto=disabled) by bios update because a lot of people is having problems.
I don't see how C-states could be the issue. They deal with the speed/performance levels of the processor. When I hear "Display driver followed by an error," it immediately says drivers, in my mind.

ASUS P8P67pro bios 1204
somebody have an idea?
I think Print Screen button loads image to memory, then when you boot windows you can paste it to paint or whatver. Not sure though.
You have to be on at least 1305 series of bios or higher and the images are saved as BMP to a flash drive if it is plugged in during the screen capture.
On the p8p67 Pro (no NF200 chip), the manual talks about using the second PCIe x16_2 (5th ATX slot) for a video card. Specifically, it states that if you put a x16 card in that slot, both that slot and the first x16 slot (2nd ATX slot) will run at x8 for a x8/x8 SLI (or CF) configuration.
However, is it possible to use PCIex16_2 (5th slot) as PCIe x1 (single channel only) without crippling the first x16 slot?
I have two PCIe x1 cards, and I just found out that once I install a Silver Arrow cooler, that the first slot (PCIex1_1) might be blocked. The PCIe x1_2 (3rd slot) is blocked by my GTX580. That only leaves the 5th and 7th slots available for PCIe.
My slots are currently occupied as:
Slot1: Asus Essence STX (PCIe x1) (for music and games)
Slot2: GTX 580 (PCIe x16)
Slot3: blocked by GTX580
Slot4: open legacy PCI
Slot5: open PCIe x16 (or x8)
Slot6: EMU 1212m daughter board
Slot7: EMU 1212m PCIe sound (for extremely high bandwidth audio work)
....
Edit: Decided to just open it up and see for myself. I've confirmed that putting a x1 PCIe device (the xonar essence STX) into the 5th slot _will_ cause the board to go into x8/x8 mode.
It appears this leaves me only two good choices: Send the silver arrow back and try to find something less bulky that still performs well, or replace the motherboard with something that offers more PCIe options.
(Replacing the sound card with a PCI version isn't an option: I don't like moving backwards. Using onboard sound might be an option, but not one I'm happy with... I've become very spoiled with the xonar essense STX card.)
Take care

People need to be mindful that on these boards they will endeavour to apply voltages to allow for a stable OC that you have chosen, so if you are ambitious like me, you too may get voltage spikes way beyond what you would expect or ever think of applying, here's my situation:
Well I was reading around and decided to try this board- was easy enough to do. The EFI bios was a nice feature quite intuitive.
Watercooled 2500k with heatkiller 3 block connected to a Thermrchill triple rad I managed to get 5.2ghz, still using turboboost and EIST - all great I thought, but in windows I noticed that running linx, temps shot up to 74degrees and CPUZ and Asus Monitor both showed peak volts for a few seconds (literally 2 second bursts) of over 1.5 vcore, stabilising at around 1.44v, which was still too high for my liking.
This is clearly unhealthy and I restarted the unit at 5.1ghz and dropped the LLC from ultra high to high and my voltage offset from .2v to .15 - all was well at 5.1 temps dropped to a peak of 74 degs and voltage spikes were reduced to 1.438, with an avg of around 1.4v.
So I loaded up World of Warcraft and some monitoring, left it running in windowed mode and all seemed well - I decided to make a drink and grab a cig (at which point I was thinking about dropping it to around 4.9ghz and keeping volt peaks at 1.4vmax), came back to me PC to find it dead as a dodo.
Tried to fire it up and got a slight power twitch (fans turned about 1/4 turn) and nothing - so I read around, reset the cmos, did the battery trick tried again, still nothing, repeated all again swaping out my corsair HX850w PSU for a PCP&C 1kw unit still dead, left cmos reset on and removed battery and left it overnight - tried again this morning after a good 12 hrs discharge and its exactly the same.
I always found intel processors to be failry robust so I hope thats not fried - I am hoping it's the board (or just the board and not board and CPU).
Still I'd welcome any input on this phenonemon...... I think I will stick with Gigabyte UD4 when I RMA this, the featureset is nice but the 'boost' technology is too immature to cater for people who expect the voltage parameters they set to be the ones they get.

AFAIK, there is no video card using more bandwith than what a x8 slot can give (32 Gbits/s with PCI-E 2.X)Quote:

Maybe yes, but LinX also using AVX and the proc is not so new anymore. LLC at normal/auto I get an error in LinX.
Shall test again without AVX/older LinX.
I benchmarked the difference. It wasn't a large difference, but somewhat noticeable. When I'm spending hours trying to get "just one more multiplier" out of my CPU, it's hard to justify any performance drop due to slot design on the board.Quote:

(It was consistent over 3 runs.) The others were less significant (or less consistent over multiple runs.)Quote:

I ended up taking the xonar essence STX out of the machine and I'm using the on board realtek sound for now. I'm hoping that the next round of P67 (or Z68) m/b's have more PCIe options for those of us trying to leave legacy PCI behind. (The irony is that the Essence STX board is actually a PCI board with an extra chip bridging it to the PCIe x1 interface... the same is true for my EMU 1212m sound card.)
Take care
Gary
Well, those results sound strange. You shouldn't see such a difference :/ But I don't know of any method to verify if the slot is in 16x, 8x, or less.
About the PCI-E lanes, don't expect too much as it is inherent to the P67 arch (8 PCI-E lanes according to wikipedia)
GPU-Z shows the number of lanes being used, but I don't know of anything that actually measures the bandwidth.Quote:
Originally Posted by Khoral
As for the limitation on the number of lanes, there are actually enough lanes to support what I want, but the motherboard (or perhaps the BIOS) doesn't let me allocate them the way I want (or has the slots in a physical location that isn't working for me right now.) I started to consider the p8p67 deluxe (as it has more options with the PLX chip), but it would have the same PHYSICAL issue as the Pro. Perhaps the WS Revolution would work for me, but it'd be cheaper for me to buy the legacy PCI version of the Xonar Essence!
I could also stop being so spoiled about my sound cards. ;)

?Did you look at some other manufacturers too ? Like Gigabyte with their UD5 and UD7 ?
Well for me I would just say, look at your voltages when running linx, something funny happened to me and the board had volt spikes beyond 1.5v, which after a short while fried the cpu and board.Quote:

Running a 2500k at 4.9ghz, running Linx, under load the voltages peak at 1.458v - is this okay for everyday use with Watercooling, temps are 68degrees @ max load

These are all the settings I tried, don't seem to make difference from default:

CPU Current Capability: 130%
I use LLC Regular, but I don't see how this could be a problem, works fine with 4.6GHz, even more voltage doesn't help Prime Blend stability.
Edit: actually, it seems 1T/2T memory command rate was my difference between 13xx and 15xx bios. with 1T I lost 1 multiplier at every voltage range as apposed to 2T. so, ignore some of my comments below. though I'm not sure if one bios was better than the other still.
my Deluxe/i5 2500k has been rock stable 4.5GHz for about 4 weeks now. I used offset but required more voltage during load, so I use offset off now. still waiting for new BIOS from Asus. seriously where are the bios updates? I liked 13xx bios better, seemed to get better results. (lost about 100mhz in every voltage range, I think related to memory somehow) but can't downgrade now. and I still want the offsets fixed, it overshoots the mark too much and still drops. gigabytes are more on the mark and less jumping around. so, come on asus...
Anyways here's my 24/7 4.5GHz settings. I'd love to get more like 4.7-4.8 if not 5.0 though. waiting for new BIOS though.
Vcore: 1.355 Bios, 1.64 idle, 1.352v under load w/ prime95
RAM: 2133MHz, lowered to 1T stable. no extra VCCIO required.
DIGI+ VRM Load-Line Calibration: Ultra High
DIGI+ VRM Current Capability: 140% (I could probably lower this)
DIGI+ VRM Frequency: Auto w/ Spread Spectrum
DIGI+ VRM Phase Control: Manual; Ultra Fast.
DIGI+ VRM Duty Control: Extreme
EPU: Enabled/Auto
CPU Spread Spectrum: Disabled
C3/C6/EIST: Enabled
my previous 2500K had memory controllers crap out too after awhile. combination of 1T and high volts/overclock I think did it. I'm hesitant to OC my new one past 1.39v because of that.Quote:

people seem to be reaching 5GHz even on the sabertooth (8 phase) so, I wouldn't think it matters so much. maybe only in the real extreme 5.2+ ranges. Asus has a guide here somewhere and they pretty much say the same thing.Quote:

You are correct, the 980X CPU will only work on the X58 chipset on socket 1366. Sandy Bridge, is as you mentioned on socket 1155 and SB-E will be on socket 2011 using the X68 chipset ( http://www.techpowerup.com/138087/In...-Pictured.html ). As you can probably surmise, the X980 CPU won't work on either of these chipsets (it's uses a different socket). Ivy Bridge is the die shrink of Sandy Bridge, but whether IB will work on exists Sandy Bridge MB with a BIOS/UEFI update remains to be seen. If you're really set on keeping the 980X, then you are pretty much stuck with your current MB as it won't work in the any of the motherboards designed for either SB or IB.Quote:

wonder what else I can try to squeeze more MHz without going over this voltage wall? I'm thinking of tweaking VCCSA and CPU PLL, but not sure which direction I should be going in (up? or down?)
also, i've heard people say they can get higher clocks with lower load volts with LLC off, but wouldn't that mean higher overall non-load volts? or higher half-load volts if the load isn't enough to vdroop significantly?
Yes, non-load voltage is higher, but only by a small margin, around 0.01V, but load voltage with LLC off is 0.03-0.04V lower than LLC High.Quote:

I would say to 4.6GHz you are best with LLC Regular, but 4.8GHz isn't stable with Regular and requires LLC High, haven't yet tried LLC Medium though.
Lower as far as possible, but these voltages only bring lower power bills, nothing more. Actually, running Prime at high CPU frequency to figure how low you can go, you're actually doing nothing good, not to costs and not to CPU health, I guess it's just for personal pleasure.Quote:

To give you an idea how much, I am stable with:
4GHz
VCCSA Voltage: 0.80000
VCCIO Voltage: 1.00000
CPU PLL Voltage: 1.52500
PCH Voltage: 0.92000
4.6GHz
VCCSA Voltage: 0.81250
VCCIO Voltage: 1.00000
CPU PLL Voltage: 1.52500
PCH Voltage: 0.94000
4.8GHz
VCCSA Voltage: 0.81250
VCCIO Voltage: 1.03750
CPU PLL Voltage: 1.53750
PCH Voltage: 0.95000
Determining CPU PLL is the easiest, if it boots you are 100% stable, Prime 12h+, LinX 20 passes etc., regardless of the CPU frequency.
sorry maybe a little off topic, but I've had no luck getting my L041C123 past 4.6-4.7 with <1.38v.
I got a 3rd 2500k today, a costa rica chip, batch # 3101A127. first impressions: not impressed. been up all night with it and it seems to clock identically to my L041C123 malaysia chip. (see sig for clocks/volts range) but it refuses to do 5.0GHz <1.45v (probably needs 1.5v) my first 2500k was horrible and would barely even do 4.6-4.7 before it's memory controllers died.
how hard is it to find a chip to do 5GHz under 1.44v? /sigh (preferably 1.4v)
hope my P8P67 Deluxe isn't limiting my clocks somehow. I'm still not convinced 1503 bios is better than 1305 wonder why Asus hasn't released a new BIOS lately, they must be working on Z68/X68?

Pretty hard, I know someone that went through 20 chips to find one that could do that.
What specific problem are you having on 1305 or 1503? If everything is working ok for you, it's a good sign.Quote:

My 2500K does 5ghz linx w/ avx stable @ 1.42V and 4.8ghz @ 1.35V (my 24/7 oc). The batch # is L045A848. This is the only chip I bought. It'll boot windows and run superPi at x54 multi with 1.5V. I'm using a P8P67 Pro and have the same results with 1305 and 1502 bios. Guess I got fairly lucky.
my new 2500K was priming fine for 6 hours at 4.9 when it was brand new, and now it locks up almost instantly. more volts eventually BSOD's 101/124 after 2-6 hours. can't even get 4.8 stable either on it. seems like junk, or something else I dunno. and my other 2500K was having problems doing even 4.7/1.376 which It used to prime 12+ just fine. I'm starting to wonder more and more if maybe something else in my machine is causing problems. or is it normal for chips to degrade like this? sofar i've seen it in all 3 chips i've owned. (first one stopped doing 2133MHz memory even at stock)
default volts for this new 301A127 is 1.165v/3.4GHz so it looked promising.
and BTW, i envy those of you with enough cooling for LinX+AVX lol
no problems @all with my 24/7 settings written in my sig. maybe u have some other troubles @ur sys. itīs strange that all ur 3 chips r degrading on that fast way. which vcore etc.. did u use for benching ?
btw. i have done the LinX stess test and joined the club ;) no degradation unitl now :D
I was priming 4.9@1.43v and 4.8@1.4v and it seemed fine until I left it overnight.Quote:

It could be that you are killing the memory controllers in your chips. Your sig says you're running 1.66V, 2133mhz 1T. That's about as hard as you can push the IMC. The stock voltage for Sandybridge ram is 1.5V I read that it really only should be overvolted up to 5%, which is 1.58V I'd suggest that if you get another chip, you keep the ram voltage at 1.55V or less.
