It doesn't work like that. Some straps are stronger then others. So even with slower ram speeds you can't reach hiegher blck. So stick with the strap/divider that works the best for you.Quote:

Wow. So now we are maxing out our bandwidth capability of the board??Quote:

i just let it without any overclock, i've tested the ram with memtest 4.0 default and under overclock and it has no problem as long the cpu is on default setting, it must be some sort of incompatibility, i really can't figure this issue out, my psu is a brand new enermax pro82+ 525w , i only have a 9800gt vga so i don't need more than this.Quote:

I have the F8 bios on my UD6 board but makes no difference even using F8, F7 or F6 bioses, running @ defaults. I've checked and double checked the wiring on the motherboard from the case and everything is in its right place. In the end, the only way to turn off the computer is to hold in the power button on the case for 4 secs.
I believe it's some sort of compatibility issue as well, however our memory is clearly listed in the comparability matrix.Quote:

i don't know how RMA policy is on youre country but here in Romania i can't RMA my board if on default settings works without a glitch:(. Anyway paying 200$ for a board which won't overclock sucks big time.Quote:

Stupid question here, but can I install my videocard into the PCI-Express X4 slot on my P55A UD3? Physically it's compatible with my X16 size card, but because my videocard is too long, it won't fit in the regular X16 slot since the hard drive cage of the case is in the way. If it does work in the X4 slot, will the X4 limitation severely limit performance? This is going to be temporary until I get a new case!
Yes, installing a video card on a 4x slot will limit its perform up to 20%, as I recall.
I just picked up a P55A UD3 and am waiting on a retention bracket for my TRUE so I haven't been able to try it out. Hopefully tomorrow. Anyways should I have any problems hitting a 200 bclk on an 860 for 24/7? I'm a little concerned with vrms providing enough stable juice and possibly cooling. Should I be?
Thanks in advance
Interesting comment there. I wonder if it's a fact? I have no choice anyways as the hard drive cage is blocking my videocard from being installed in that slot!Quote:

What voltages are best for stable overclocks above 214 BLCK? I can't get my system stable with 215 BLCK testing on IntelBurnTest. 2:10 & 2:8 straps work best for me. I'm using 860 with UD6 board and F8 bios. Any helpfull suggestions much appreciated. :)
I was in the same boat with a couple Thermalright and Noctua coolers with older mounting packages. Finally got them in from various places - limited stock and locations to order from.Quote:

4X PCIe is enough for physics purposes. Not sure there's enough benefit to bother using it when you're running two very capable graphics cards already. Plus, there's other boards that limit its use whether it be SATA ports or what not. That's just a couple feasible reasons why we see vendors omitting that extra slot.Quote:

After installing the two utilities and one new driver for the P55A-UD6, I managed to get Sequential 256 MB/s read and 184 MB/s write rates. While these are noticeably faster rates than SATA2, it's not the fastest I've recorded. Hope a new tuned driver pops up to get upwards of 300 MB/s. :)
stupid question guys, but how do I enable AHCI in the BIOS? I want to install an Intel 40GB SSD on the integrated SATA port (intel chipset) and not the Marvell chip.
My motherboard is the Gigabyte P55A-UD3.
Thx!
Integrated Peripherals
Intel Controller (Blue Ports)
SATA RAID/AHCI Mode (Intel ICH10R Southbridge) ............. AHCI
SATA Port0-3 Native Mode ................................... Enabled (or Disabled, both will work)
Then install your OS with the Intel AHCI Driver, or update it after install if you want.
Are you sure that's the name and order of the options under Integrated Peripherals? I'm at work right now, but I don't recall seeing the options under those names in the BIOS. Are you doing this from memory?Quote:

What does the Extreme Hard Drive XHD function do? The other guy had it disable, but you're suggesting that it should be enabled.Quote:

Is anyone using aftermarket mosfet coolers on any of these boards? I would love to throw a couple of HR-09s on my P55A UD3.
I haven't tried using anything as fancy on these UD3 test boards. I tried some make-shift aluminum mini-sinks and one piece heat sink parts from other boards. The mini-sinks didn't work out too well - bad thermal tape me thinks. Using thermal paste actually helped transfer heat far more efficiently.
Those HR-09s look pretty cool. Too bad they don't come in polished black. :p~~~

Is there a beginner guide around, or some bios screens?
I just got a ga-p55a-ud3r and an i5 750
I'm just after a fairly light overclock. 3.4 or 3.6ghz, and keen to get my ram timings down.
I've been reading miahallen's review
http://www.xtremesystems.org/forums/...d.php?t=235289
and it mentions "Next up, I've got some 24/7 settings for you everyday overclockers", but there is only bios screen of the voltage. Hoping for some more info :)
See this screen here....
http://i161.photobucket.com/albums/t...n/IMG_7219.jpg
Is 'Normal' actually the cpu's correct stock voltage? Or is the bios just giving a general safe value for 'Normal'?
I'm wanting to know what my stock voltages are so I can manually set them.
And what's the XMP thing?
If you look at the printout from CPU-Z you will see many things the app does not display on the screen. One of them is the XMP setting.
Various tests show that pushing RAM speed does little to augment performance. Don't bother.
Where do you live that you were able to get a GA-P55A-UD3R? In the US all I could get was the GA-P55A-UD3P.
New Zealand :)
What's the difference between P and R? (apart from being different letters, har har)
Thanks for the CPU-Z tip, I did not know that
The -P has an unneeded chip on it. Waste of money. And I've seen -R's featured in major feats of overclocking. Not so the -P.

Gday peeps, just ordered the Gigabyte P55A-UD3 and an i7-860 as a cruncher for Extreme's upcoming WCG run. I was planning to pull 3 sticks of Trident PC2000 DDR3 RAM out of my main rig so as to keep costs down for now.
Does anyone know if this board will run 3x2 gig sticks of RAM or do they have to be in pairs?
TIA

Try it and see. Then report your results.
Official F10 BIOS has been released for the GA-P55A-UD4, haven't checked the other boards...
F10 2010/04/23
1. Update CPU microcode
2. Improve PCIEx16 slot compatibility
I wonder what it means by the 2nd one there? I know the first one updates micro code to allow the i5 680...
does anyone know if bitpower or the EK full waterblocks for the X58-UD7's
fit on the P55A-UD6/7's?i would like to get a nice looking block for my new
P55A-UD7,the ones that cover the PWM/NB/SB areas.

I picked up a P55A-UD7 yesterday, LLC1 has major vdroop compared to the P55A-UD6 and the X58A-UD7. 1.46125vcore in bios to gives me 1.376vcore load using LLC1. When set to LLC Standard, 1.46125vcore bios gives me 1.340vcore load. Also tried dynamic vcore, I still get droop using it, 1.424vcore idle-1.392vcore load. I am on the latest bios F5, I am wondering if I got a bad board or is this normal for the UD7?
with mine i set 1.312v in bios using LLC1 and get 1.28v idle and 1.26v load,w/bios F4
i will do some more testing in the next two days and let you know my findings
Thanks radaja.
This is using LLC1, inbetween loops 13% cpu usage.
http://img580.imageshack.us/img580/4196/drooooop.png

This is 100% load, it toggles between 1.392 and 1.376.
http://img694.imageshack.us/img694/9...ooooooooop.png
Uploaded with ImageShack.us
With no load on the cpu vcore in cpuz reads 1.456v. This much droop cannot be normal for LLC1.
I have not tweaked the voltages yet, but it seems to require more vcore for the same oc than my UD6.
I am pretty sure there is something wrong with this board. Now when trying LLC2 it locks up at exactly 7 seconds into linx no matter what vcore. I have flashed back to f3 bios and have the same results. Will send this beotch back to the egg and get a refund.
My board makes a lot of noise under load too, it's definitely not the most reassuring sound out there.Quote:

Now this UD7 is flaky with llc standard, 1.45vcore bios gives me 1.264vcore load. Has to be the board, have switched out PSU and otherhardware. tried almost all bios's. My UD6 has been just awesome, I think Ill rma this and maybe get a SSD instead.
with 1.64v on vddr from bios, what do you see real from windows?
the last time et6 not work, has already happened to someone? (no change voltage for example)
@OC Nub,hey i just tested using LLC1 with 1.37v in bios give me 1.34v idle and 1.31v load.Quote:

OC Nub which did you use on you UD6?level 1 or 2?
Thanks for testing that radaja. I put in for an RMA on the board, it just kept getting worse. I will try another UD7, hopefully the new one will be good. I havent had any issues with Gigabyte before.Quote:

yep,im trying level 2 now because i need 1.34v for 4.2Ghz and wasnt liking the 1.39v idle with level 1
so now with level 2 i set 1.3375v in bios and get 1.34v idle and 1.34v to 1.36v load
Well, I think maybe the UD7 is fine and my 870 is flaky. I tried the same oc, 4.3ghz using LLC 2 on my UD6 board and it freezes up at the same time in Linx no matter what vcore. It does pass LinX and run fine using LLC1 on both boards. The vdroop is slightly less on the UD6 but not by much. I dont know if this is good news or bad, the chip cost a lot more than the board.
Wish this was real, I think Everest bugged out.http://img227.imageshack.us/img227/6929/cachemem1.png

thats great news

@ radaja, I am able to get stable using the p55a-ud6/i5-660 at 4700mhz. I have been able to get the same chip stable at 4500mhz with the same voltages using the p55a-ud7. But...I cannot even boot into windows at 4600mhz. I have tried lowering the qpi link, raising vcore, vtt and pch voltages, also raised the pci-e freq but nothing seems to help. Any ideas on what to try next?
Edit: ok got into windows at 4600 and running linx, but had to drop qpi link to x28, for 4500 it was set to x48. This seems very low, on the ud6 I believe I used x40 for every oc.
There's a problem guys. For some odd reason, my motherboard is now stuck hanging in the POST screen.
So this is what happened. Earlier today, I put Windows 7 on my USB flash disk to install on my computer. I went to the BIOS to change the boot order to USB HDD, but for some odd reason the motherboard won't recognize the flash drive and boot from it. So I went to the hard drive boot list to change the order so that the USB flash drive is on top of my SSD. Once I restarted the computer, everything booted up fine and Windows 7 proceeded to install. Once the installation was completed, the computer restarted as normal, but now it just hangs after the POST screen. It's at the Serial ATA AHCI BIOS list and it shows the first device on controller bus#00, which is my blu-ray reader. It just hangs right there. It doesn't list the SSD or any other components. I tried to press "delete" to access the BIOS, but it doesn't work. I restarted the computer many times and even removed the flash drive, but the mobo will attempt to load, but it'll eventually get stuck on that screen.
So what do I do right now?
with 1.640v from bios how can you see in windows real with hwmonitor or everest or et6?
devil mcry- this is with 1.66vdimm bios, everest reads 1.65v. I guess you are talking about dram voltage?
i never understood why gigabyte cant do 1.65v in bios?why do they need to be even numbers with vdimm?
oh well ive got my 980x coming so my UD7 and i7-870 are going to be sold cheap,real cheap:D
yesss thanks for feedbackQuote:

Another question, I see you have the bios F8, I put the F9, which is in your opinion better?
devil_mcry are you measuring under load or at idle?mine with 1.66 in bios in everest and ET6 drops
to 1.64v-1.65v and idles at 1.664v
1.664 only under idle I didn't test 1.66 under full load because my ram is 1.60v from specQuote:

Also, does anyone here know how to remove the CMOS battery? If I can't get a hold of a jumper, the only other way that I'm aware of to reset the CMOS is to remove the battery and wait 1 minute for it to reset. I have never removed a CMOS battery before and could use some advice before I :banana::banana::banana::banana: up my motherboard.
Thx!
There is a little tab that sticks out where the battery is held in, I use a small flathead screwdriver or a pen and press down on the tab. That should release the battery, just be careful.
Did any of your Gigabyte motherboards came with a jumper? I find it odd that mine didn't came with one.
on ud6 there is a switch
UD7 has a little button
So UD3 owners got the shaft?
yep,thats the way they do it.little things get left out for the cheaper boards.
but the good thing with gigabyte is their lower end boards OC like champs
Hmm. My machine's running a test right now so I can't look, but I'd swear I put a jumper plug on my P55A-UD3P when I needed to reset it.
In the manual you can see the CLR_CMOS jumper on the diagram page. You can DL your mb's manual from Gigabyte.
yea i remember on my P55-UD4 it had the jumper pin too.i think?
by the way great combo deal in the FS section
I have the manual in front of me. I looked at it and I don't see a jumper on it or on the board. I am serious here. Did you got the jumper from elsewhere?Quote:

Gigabyte P55A-UD3 won't boot up - XtremeSystems Forums
This is what I see on the screen of my desktop as it hangs upon booting up the Serial ATA ACHI BIOS
So here I am back in square one. What do I do now? I'm completely puzzled by this.Quote:
Serial ATA AHCI BIOS, Version iSrc 1.20E
Copyright (c) 2003-2008 Intel Corporation 23

Please wait. This will take few seconds.
Controller Bus #00, Device #1F, Function#02: 06 Ports, 03 Devices
Port-00: CDROM, ATAPI iHOS104 (this is my blu-ray reader)
That happened to me when i my harddrive died mate :( I would do what that guy says, try it in another pc, if it works format it and then try again in ur pc.
I took a close look at my P55A-UD3. The CMOS-CLR header is about 1.5 inches up from the front panel ports. It consists of only two prongs instead of three and it doesn't have a jumper on it. All you have to do is use connect the two with the tip of a screw driver for about 5 to 10 seconds. (I'd do it twice just in case.)
And, on a side note, I had the P55A-UD6 running flawlessly with some new test memory. Even though many of the GIGABYTE P55/P55A motherboards say they support up to 2200MHz DDR3 (overclocked), this board was perfectly fine at 2400MHz.
The stuff used is the Patriot Memory Sector5 4GB 2400MHz DDR3 dual channel using the XMP profile timings 9-11-9-27 2T. Manual overclocking was a little trickier. Auto memory voltage settings (VDIMM) kept trying to boot the memory at 1.5V which is too low. Manually setting the memory voltage to 1.66V in the BIOS let me go crazy with all the CPU frequencies.
So, either way, my test platforms confirmed 2400MHz DDR3 works. You may have to update your BIOS if you encounter sporadic issues. Happy clocking!
tnx bro ;)
the only limit of max dram frequency, for this board, is bclk lol :D
over 210 is very hard to run stable, therefore max dram frequency is probably 2500mhz, i think
My Bclk max (on water) has been around 215/220. But, it takes quite a bit of voltage finesse and running my CPU on the hairy edge of RMA. My test CPUs have all been pretty decent with the exception of my Core i7-875K processor. All the rest can keep up with the boards for the most part.
The fact that the fastest dual channel DDR3 memory on the market is 2500MHz alone gives away the near maximum support Bclk average. There's really no way to run my CPU and the DDR3 memory at its max for too long. My poor little P55A chipsets. :p
:D realy, after 2000mhz of ddr3 becomes really useless, the benchmark
but it's possible XD however the memory controller of lynnfield is very very powerfull
I have a little problem with my ud4p. Very often after restarting and especially if I do some changes in BIOS, motherboard read very low CPU temperature, even negative degrees (- 17oC). Which of course isn't real, I use air cooling. And the consequence of this is that CPU fan doesn't start to turn. Any ideas which is the cause to that problem and what can i do to solve it.
Right now i'm using F11C bios, but the same thing happened when i was with F10.
Thanks in advance and apologies for my awful English.
I had this trouble a few times. Re-seat your cooler. I am not sure of the cause, but re-seating the heatsink solved the problem for me.Quote:

Is there a such thing as a bclk hole like the fsb hole on the s775 boards?
I could not boot into windows with my i3-530/UD7 at 205x22 no matter what I tried (chip is stable at 4620mhz on my ud6) just trying stuff I lowered the multi and raised bclk, now I am in windows at 215x21. Stability may be another story.
Edit, I figured that problem out. boots fine now
For most games this would be a good gaming rig. Installed an Asus EAH4890 and running some 3dmark 05.

Wow, I'm so surprised that no one here has figure this out or even experience this problem. After spending hours on this problem, I am now confident that the problem lies in the fact that the Gigabyte P55A-UD3 motherboard has a problem with my Liteon iHOS104 Blu-Ray reader in AHCI mode. How do I know? Everything works when under IDE mode, but it'll hang if AHCI is enabled and only by resetting the CMOS, can I access the BIOS.
Over at Anandtech, one of the reviewers for the Gigabyte H55-USB3 experienced the same problem as me:
Gigabyte H55N-USB3 : Mini-ITX done the Gigabyte way... - AnandTech :: Your Source for Hardware Analysis and NewsQuote:
Setting AHCI mode for SATA ports results in not being able to boot from our Pioneer 215-DBK SATA DVD drive (IDE mode works fine). Fortunately there is a workaround for this, press the pause key during the POST sequence just before the drive boot sequence starts, let the board pause for a few seconds and then resume. We’ve reported the problem to Gigabyte and a fix BIOS should be up on the support site shortly, so you won’t need to work around if you flash over.
Unfortunately, pressing the pause key didn't help me at all. The screen will pause and then nothing will materialize as I wait.
Wow, I'm surprised that no one else has experienced the same problem as me.
Did you guys plugged both your optical drives and SSD on the Intel SATA controllers without any issues with AHCI enabled? I can't get it to work under that scenario and this is frankly pissing me off.
what is trusted DES gigabytes?
