It reminds me of the old asus pc probe, a horrible program.
Oops. Double post.
Any suggestions for a version of ET6 for P55A-UD3/R/P that works?
And is anyone having issues with temps? My basement is 18.5 to 19C ATM, and my core temps at idle are running 21 - 22C on Speedfan and Real Temp - understandable with a Megahalems. But a "CPU" temp ("Temp3" on Speedfan) of 9C should not be possible. At least it is consistent: when I let my cooler fan run on auto, it backs off to 530 RPM and the "System" temp rises to 12C.
Then I ran LinX. I can see that I will need to re-seat my Mega: an i7 860 at stock speed and default voltage should not show max core temps of 69 to 80C. Heck, my Freezer Pro 7 has done better than that.
I'm thinking I may have a bad MB: the AUTO setting for Smartfan does not seem to pick up that it is dealing with a voltage-regulated fan. And the SYS_FAN2 header runs its fans at minimum, whether they are PWM or voltage fans.
The ET6 that came with my P55A-UD3P was on a CD-ROM that billed itself Version 1.0.2. The ET6 that came bundled with my P55M-UD2 was on a CD-ROM that billed itself Version 1.0. Uninstalling version 1.0.2 and installing 1.0 fixed the Smart Fan issue.
BTW - in theory the SPU fan header is supposed to report the RPM of the PSU fan to the MB. On my P55A-UD3P, it also powers a fan.

Looks like you got a great 860, nice work again with this board. :up:
Snowed in today, so I explored my new i7 860 and P55A-UD3P, all at default voltages:
BCLK = 195MHz x 21 @ 4098MHz ran a full set of LinX.
BCLK = 197 x 21 @ 4140 did not finish the run.
BCLK = 207MHz x 20 @ 4144 ran a full set of LinX.
BCLK = 208 x 20 @ 4163 did not finish the run.
BCLK = 225MHz x 17 (mem at 6x) @ 3829 booted and loaded OS, arrived at desktop.
BCLK = 230 x 17 booted and loaded OS but crashed as soon as the desktop appeared.
BCLK = 200MHz x 21 @ 4203MHz booted and loaded OS, arrived at desktop.
last night a BCLK = 200 x 21 did not complete the LinX run.
I have not pushed the x21 series simply to load OS - yet.
The PSU is a 750W Antec. At the higher CPU speeds ET6 reported Vcore = 1.392v and Vmem = 1.632v. These held stable during the stress parts of the LinX runs. I think that is a testament to the ability of the MB's 12-phase VRM.
hey ive got a h55M board and it does this strange thing with vcore.if i set 1.225v in bios with LLC enabled it gives me 1.23v idle and 1.24v load.
so my question is,do these p55's do the same thing?with my p45 there was always some drop,like 1.32v bios would 1.31v idle and 1.29v load.thanks
The UD6 has LLC 1 and 2, LLC 2 over volts, also on the EVGA P55 FTW LLC over volts. The vcore actually increases under load.Quote:

My sys_fan1does not vary. It stays at max. My sys_fan2 also does not vary: it stays at some kind of minimum.
Is this normal for P55A boards?
I picked up an i5-660 today, I just started messing with it. What is up with the weird memory timings? I set 7 7 7 20 in bios and it shows 10-7-7-20 in cpuz.:shrug:
Heh. I set up 7-8-7-etc. on my P55M-UD2 and got 4-8-7-etc. on CPU-Z, and CPU-Tweaker.
I raised the QPI clock ratio to x48 and it gives me cas9 now. Weird chip, maybe I should get an h55?
The easiest 4500mhz boot I have ever had. I doubt it is stable but I will work on that later.

yea i have the same issue with my H55M-UD2H.if i set 8-8-824 cpuz show 9-8-8-24.and when i messed with static tRD setting,from auto to 10 then cpuz showed 5-8-8-24 instead of 8-8-8-24
Maybe adjusting static tRD will help get the correct timings?Quote:

after i changed it from auto to 10,i tried to set what auto showed and set it to 14 and still kept coming up as 5-8-8-24.i tried 13 ,9,8 then
when i set it back to auto after two boots it went back to reporting cas one too high again(9-8-8-24)i think its just bugged
EDIT-i just set 7-7-7-21 in the bios and cpuz and everest report 8-8-8-24
when i set 7-8-8-24 in the bios cpuz and everest report 8-8-8-24
and it seems to only change my cas to 5 when i set the tRD to 10.
but nothing changes my everest scores?going from cas 9 down to cas 7
its like the memory settings dont do anything.

okay note for clarksdale. The f6 bios at the top of the list on page 1 is no good. you want the f7 bios for ud6. f6 sets my x16 at x8. I came across this same issue on msi gd65. they gave me a beta bios 1.73 but bclk on that board with clarks maxed at 200 on dice so I sold it and bought the maximus III formula and and a ud6. I just insulated the M3F. now I'm gonna pull the ud6 off (im curretly on it typing this post) insulate it and hopefully by that time I have a decent bios to work with. in the meatime Ill see what I can do on F7 bios.

this somehow adjust something (which i dont know), but CPU-tweaker / CPU-z / Everest would show bios-set memory timings.
anyway, as far as i could see there was no system stability problem.
i normally try not to use the fan plugs on motherboards, also disable the CPU smart fan in bios.Quote:

I wondered about that. But the auto fan controller for the cpu works like a champ. It even flies blind: it will adjust 2-wire fans based on the cpu temps. It's most remarkable to see.Quote:

Im working on getting 4600mhz stable now. It failed last night after 14 passes of LinX using max mem.
Changed the CPU multi to x25 and upped the bus speed to 184, set timings to 7-8-7-20 and passed 4600 using 2x1gb of HyperX. Will try later with the 2x2gb kit of Dominators. I wonder if it didnt like the 26 multi.
Its nice to not need an expensive WC setup to cool the chip, I'm using a Corsair H50.

is it ok to run my QPI at 4000?
I'm not positive, If I'm not mistaken I was using QPI Ratio set to x48 in bios up until today. All my overclocking on the i7-860 and 870 were done using x48 with no issues.Quote:

yea my board goes up to x40.now that i set it back to x36 it still reads my cas one lower?
maybe someday they can solve these strange issues
Pushing my luck a little bit, but having fun. Ran some spi1m tonight. Had a better run at 5100mhz but locked up taking the screeny.
I may get a cheap WC setup for this chip, it wont take much to keep it cool. So far the H50 is doing fine.
http://img39.imageshack.us/img39/1511/1m5ghz.png
Nice! That's some pretty low timings even for the HyperX 2GHz running CAS 7. Probably the CPU's memory controller getting picky at that frequency pushing some QPI V through it for CAS 7 at 2GHz. That's so close to stable though if you got that far.
Thanks, I was using 1.50vtt and 1.680vdimm.
After reading about many dead Clarkdale chips I am a little nervous to keep pushing. But this is almost to easy, makes it hard to stop.
I recently picked up a Core i5 750 + Gigabyte P55A-UD3 bundle at Fry's for a pretty good price. I don't plan on doing any EXTREME overclocking, but I would like run to a decent 24/7 overclock. Can anyone weigh in and tell me if it would be worth the extra $50 to upgrade to the UD4P, mainly for it's 12-phase power regulation? I have no use for most of the other features offered such as dual LAN, better onboard sound, or SLI compatibility, so I'd really appreciate if someone could weigh in on the OC potential of the UD3 versus the UD4P, and if it is indeed a more robust board outside of the features I mentioned above.
Hi there Wompa. Check out what "ehume" (farther up the page) has been getting with his UD3P. His board is a good choice too, if you don't need the UD4P's extra features. I've had different Core i5 750s on a UD3P and UD3R reaching 4GHz. Auto BIOS settings weren't so forgiving with the UD3, so I had to do a little tweaking.Quote:

Hope this helps!
I'm running 4GHz routinely on the P55A-UD3P. Rock stable. Even the voltages are stable, which I attribute to the 12-phase VRM.
I run LinX to test cooling fans with my Megahalems. My sole difficulty is my inexperience with applying TIM properly. But I'll get there.
As Temujin says, choose your board for the features. The 4P/4R and 3P/3R are all quality boards. Check out this review for example.
Guys,please check this updated version:Quote:

Right on. Figured there would be a .2 pretty soon. CPUZ hasn't been working very well for the last X58 and P55 chipsets. I've had to rely on the motherboard vendor's bundled software to validate and confirm some of the memory settings. Oh well, moving forward. :)Quote:

Playing around some more today with the 660, put it on water. Am working on lowering vcore a bit but so far this is where I'm at with it. Just doing short Linx runs, its stable at 4600mhz 20+ passes. The sensor on core 2 is a bit buggy I think.

OC nub,do you have LLC disabled? if so what do you need to set in bios
to get 1.39v idle/1.37v load ?
Its set to LLC1, still has some droop but not a lot . The bios is set to 1.4225 I believe (just took the chip out so cant see it in et6), that gives it 1.392 idle. Any higher and it goes to 1.408 which is a hair above Intel spec, with the short history on these new chips I am afraid to do much testing above that.
congrats my friend thats insane :bows:Quote:

radaja, Thats about all I could get it to boot at using a 12 multi and up to 1.4vtt, but that was with the i7 chip. I don't know what kind of difference I will see with the i5-660 if any.
hey OC Nud.do you happen to know if PCH voltage helps with high bclk? or is it strictly Qpi/Vtt voltage?
i'm having trouble stabilizing 237 bclk.im running 17x237 right now to try and get it stable to do my x19
run.but after an hour it fails during the 786fft's and i've raised my vdimm one notch and qpi one notch
but still it fail.19x234 worked fine,but its just this 237 thats wont prime all the way.
I went up to 1.120vPCH from 1.080v and it did help with stability for high clocks. Weather that was Bclk related or not I am not sure. PCH if I understand it correctly would be like MCH on a p45.Quote:

If you know your cpu requires 1.350vcore for say 4400mhz , and the vid on your chip is 1.200v, you would just add +0.150v to dynamic vid. I'm not sure why they even put the - voltage there.
yep.right now im trying 1.13+0.125=1.255v for 21x200@4200.
because when i did it with the regular vcore and LLC enabled
it would either be 1.248 or 1.265v or 1.28v so im trying to find
the middle ground for my lowest vcore for 4.2

once in Qflash click update from bios from drive
your usb stick will show up as HDD-1-0 click it
then you should see the bios file
it just comes up with no drives found
Hmm. I used the Windows based app to update my BIOS from a file on disk. I also did this several times with my P55M-UD2. Never had any trouble with it.
I'm having some problems with my GA-P55A-UD4 and i5 750, mostly concerning QPI/VTT.
First of all, is it normal to get varying results for read and copy speeds in everest cache and memory benchmark? For example at 190x20, i would run it and get 16500 for read and 19000 for copy, then if i run it again i would get 16000 and 18500, run it again and i get 16700 and 20000, happens all the time no matter what speed even at stock. Read speeds seem to vary about ~1000mb and copy is worse varying ~2000mb. On my old 775 setup the results would be consistent hardly ever varying, only if i had background apps running etc.
Now my main problem is inconsistent stability for VTT. 190 blck is when i need to start raising vtt, but the sweet spot always changes. One time it would be stable with 1.15vtt (passing good few hours of prime blend), another time i would boot up and bsod upon log in screen, and would only boot in until i set 1.17vtt or more. Then another time it would only need 1.15 again. It's nothing to do with cold boot either. Sweetspot for vtt always changes between 1.15-1.17 and 1.19 for 190blck, so annoying ! I just want consistent stability...
It's the same for higher clocks as well. It seems abit more consistent if i use the 10x RAM multiplier, needing 1.19vtt and never changing really (although i need to start using above CAS 9 at any RAM freq above 1850 which i don't really want to do). On the 8x RAM multi is when i get problems. 6x multi just seems buggy. I'm using the 32x QPI muliplier, it doesn't seem any different on the 36x.
I've tried dialing in all my timings manually as well as all the other settings, to rule out any problems with that. I've got all power saving stuff disabled etc.
I think it could possibly be compatibility problems with my RAM, as they are not exactly i5 'certified'. They're crucial D9JMN's (2x2gb).
Currently sitting at 180blck for now, with turbo multiplier enabled, ram at 1800 cas9 with 1.65v - no problems, passed 10 hours of blend.
edit: on newest F9 bios, had same problems on all the others.

unless there is something else im missing?
its USB Legacy Function enabled
also are plugging the usb drive in before you reboot?
you need to plug it in and then reboot
hit delete and enter bios and load optimized defaults
and set you boot order again the way you want it and
achi/sata /raid and other stuff the way you normally set
it to save and reboot and either hit end to enter Qflash
or delete and enter bios and hit F8 to enter Qflash.
see if this works
tried all that, still not working
The light on the usb drive doesnt even blink once, maybe the stick isnt compatible??
where are you plugging it into your case?or the back of the board?
if its not lighing up theres something wrong.try it at the back of the
motherboard and see if it lights up.
but yea it might not be compatible either.
anyone p55A ud6 users on this one? flashing now.

no problem.glad to hear you got it solved.now its time to start OCing:up:
new bios still hasnt fixed my atikmdag.sys bsod issue as seen here
http://www.xtremesystems.org/forums/...17#post4269717
life without a pc is killing me
is there possibly something wrong with you windows disc itself?
i found this and it seem to be a gpu problem right
ATIKMDAG.sys problems and TDR FAQ
here are most common reasons
i googled that error and its quite commonCode:The following hardware issues are examples that can cause a TDR event:
- Failing overclock on CPU or GPU
- Bad sector in memory resulting in corrupt data being communicated between
GPU and the system (either video or system memory)
- Corrupt hard drive/windows install resulting in corruption
to the system registry or the page file
- Over heating of GPU or CPU again resulting in corrupt data being communicated.
- GPU failure due to any sort of issue from insufficient power(VERY common) to heat.
The following software issues are examples that can cause a TDR event:
-Incompatible drivers of any sort (either GPU, sound, etc)
-Messy registry
-Known vista issues resounding around multiple displays, aero, dreamscape,
and various display drivers.
-Known vista issues that sometimes cause corrupt information to be sent to the video card
from system memory (will be addressed completely in SP2, has had various fixes applied
since vista's release)
-Bad direct x files
-bad system files
-Bad driver (some drivers will cause an event due to internal bugs, however these are not nearly
as common as many think due to all of the previous things causing the same symptom)
It cant be the windows 7 disc, as this started happening as i was overclocking when i had a stable version of windows running (1+ hour linx stable)
i noticed this started happening when i went to bios version f9 from f4, iv now gone back down to f5 and im still getting the same bsod atikmdag.sys whilst installing windows with stock speeds (its always the same part of the installation, (right at the end)
the screen goes black for a thew seconds before the bsod pops up
going to look for f4 and see if that works
if f4 doesnt work, it has to be hardware related, but what?
i only asked about the disc because i only read the last post in your other thread.
but it sounds like theres something bad with your memory or your ATI card(DRIVERS) read that link i gave you there are a lot of links to peoples fixes.Quote:
well iv just gone back to f7 bios from f9 and still cant install wiundows, its always right at the end of the installation it bsods from atikmdag.sys
let us know how you get on sorry i cant be of more help
Sorted! I reseated the cpu and now its fine
strange
thanks for the help
Hey guys, I could really use some advice. I'm having some problems with my GA-P55A-UD3 on the latest F6 BIOS.
Here’s a little history:
The first couple of days I built my system it ran flawlessly. After validating things where working solid at default speeds, I followed many of the suggestions found in this forum and pushed it easily to 4ghz (20x200), 4.1ghz (20x205) and finally at 4.2ghz (20x210) when something happened. At first 4.2ghz appeared to be stable with IntelBurnTest, Prime95, SuperPI. I then did further testing and loaded up a game, watched streaming video on another monitor while running Prime95. CPU temperatures were all under 70c. All of a sudden BOOM, system shuts down and I’ve had problems getting it stable since. Since then I cannot push it much further than 3.6ghz (18x200 or 19x190) and I’ve found that I’ve had to really push the VTT voltage into the 1.2-1.31v area whereas before, it was left at auto.
I primarily used this review as an OC template (except for RAM timings and voltage which I use 9-9-9-27-1T along with 1.64v): http://www.xtremesystems.org/forums/...d.php?t=238087
Current problems:
1) My system’s overall stability has gone to :banana::banana::banana::banana:. I’m not sure why, but I noticed something strange with my memory. Prior to purchasing my RAM I made sure it was listed on Gigabyte’s compatibility matrix. The problem I’ve been having is my system will simply shut down on its own randomly. This even happens when I’m simply web browsing, and not pushing it. Keep in mind, I can pass IntelBurnTest, Prime95 etc at 3.6ghz.
Booting into Memtest86 and running a test with both RAM modules installed immediately reboots my system. Testing each module individually works flawlessly through multiple passes. I had the RAM inserted into banks 1 and 3 as per the manual. They’re running at 9-9-9-27-1T, 1.64v per manufacturer specs.
2) I have a cold boot issue. I cannot start my PC w/out resetting the CMOS when I leave it shutdown for several hours. Upon pressing the power switch the fans power on, then off. The cycle repeats indefinitely until I reset the CMOS.
I’ve tried disconnecting every system component except the mother board power, same results. I have not tried out a different PSU yet. I have removed the CPU and inspected it and it appears fine. No burning, no bent pins. Temps have never gone above 71c.
This issue has caused me to update my BIOS from the F4, to F6. I have the same results: This system will simply not cold boot even with a very mild overclock 3ghz (20x150).
I’m really out of ideas. Is it time to RMA the motherboard, the RAM, or the PSU? Where should I start?
Here are my system specs:
I5-750 @ 3.6ghz (18x200): Vcore 1.35v : QPI/VTT 1.31v : DRAM 1.64v
Gigabyte P55A-UD3
G.SKILL Trident 4GB (2 x 2GB) DDR3 2000 (PC3 16000)
EVGA GTX 260 core 216 (no overclock)
Intel X25-M 80GB SDD
CORSAIR CMPSU-650HX 650W
CORSAIR H50 cooler

clear cmos. set optimised defaults reboot, back into bios. check your hrdw monitor make sure power and temps are stable, pull the plug and discharge the power hold button down for 3 sec. take all the ram out.
try 1 stick in the blue slot farthest from cpu. I know the white ones are the good ones but just check. lower your vdimm at stock. otherwise raise your multi to highest one and increase the bclk to the highest cpu frequency that worked while you were priming. run your qpi to the lowest setting to start so you know its not qpi. when you get above 200 bclk and ram is running high speeds qpi needs to be set all the way back to start. then as you boot and test and max out the cpu and ram then you work on maxing qpi. vtt and pch at auto to start. even vdimm can be at auto got now since its so laxed to hell.
I do this:
qpi lowest setting
ram laxed to crap cas 9 set to run under 2000mhz. start around ddr3 1600
1.5 vdimm ( to start with trident)
max out the multi to find your cpu max (this eliminates bclk bullcrap over 200 bclk.)
shut off speedstep baloney.
set all else on auto like pch and vtt even vdimm for now. set your power setting to s1 for that ssd.
you want to go in order:
max out cpu
set mem to run around around 1800 1.65v then start tightening your timings.
next max out the qpi. if ram cant keep up start messing with timings/voltage etc.
keep your vtt around 1.2 to start. then go from there.
my honest opinion get a new board. good cheap board is TH55XE. or just blow it all on a classified. ;)
i am having the same problems, so i stopped overclocking, and using default cpu and memory @1333:( i can't get it stable anymore my i750, even @ 3500, using ga p55a-ud4 and using the same memory u have 4gb gskill trident f3 pc16000 cl9. I get blue screens out of nowhere when prime passed 11 hours on that config , memtest passed 8 times without a glitch, using f7 bios. I can't understand my motherboard, it must be some sort of incompatibility between the mobo&ram and the internal imc of the cpu, or some setting for the cpu which must be turned off or left on auto.I Used max 1.25 vtt, 1.6 vdimm and max 1.33vcore with llc on for 3800mhzQuote:

EDIT: guys, i wouldn't leave vtt on auto, it sets it to way over what you need. I found it sets it at 1.40~ at 200 blck as seen through easytune, if i remember correctly.
Very interesting. I also can't overclock on my board anymore as well. My PC won't cold boot at even very mild overclocked speeds (20x150). I've ended up resorting to plugging my reset switch to my CMOS jumper just to get the darn thing to turn on. Then I set to optimized defaults, fully boot, then attempt to OC. Although still, even a mild OC will randomly power cycle my machine anymore...Quote:

PS - It is not a failed PSU. I've checked with a known working one.
Has anyone read into this thread about titled "GIGABYTE P55/H55 Cold boot / Bug fix mod"? You've got to be kidding me. This can't have to do with my cold boot issues right? blah

No No No that thread is just for extreme cooling guys (liquid nitrogen) nothing to do with your issue. :up:Quote:
