Thanks Temujin,at least this are first "Official" thread about GBT P55 series.:up:

I heard some people has reported that if you enable SATA3/USB3 on these boards you will lose SLI/Crossfire support and the first PCI-E slot will downgrade from 16x to 8x. Is this true? Will Gigabyte release a BIOS update to resolve this issue?

Is there a special reason why the P55A-UD3R / P55A-UD3P / P55A-UD4 / P55A-UD5 are not mentioned? :p

I've ordered the P55A-UD4, and hope for it to arrive tomorrow for some testing. Will be testing with Core i7 860 & KHX2000C8D3T1K2/4GX memory kit, and a TRUE rev.C. Will post here once i get something up and running.

incorrect somewhat you don't lose SLI/CF support

what happens on Gigabyte P55A boards is

1. either USB3.0 or SATA3.0 can run at full speed but not both, the other device will run at 250MB/s reduced speeds
2. when either USB3.0 or SATA3.0 is used PCI-E 1st slot bandwidth reduced from x16 to x8
2. SLI/CF will reduce both USB3.0 and SATA3.0 speeds to 250MB/s

You're very correct. All P55 and P55A motherboards are naturally included. There are a handful more boards that are on the Taiwan site not released every where just yet. :) I'll do a little editing since the active list will change.

And, eva2000 is exactly right about the PCIE bus sharing. CrossfireX/SLI are not lost. There is very little real world performance differences, if any, when switching from x16 to x8. The P55/P55A Chipset is a strong performer.

I wondered how the first back of P55A-UD6 performed being a curious consumer at heart. I wanted to see where the board and Core i7 870 would go on F3 BIOS, voltages, and using XMP Profile 1 settings. Of course, Speed Step and Turbo were disabled just to make sure there's no extra help. So easy, anyone can do it!

I had a chance to test out the GA-P55A-UD6 also, but with a rather poor 860 which has seen some use before I recieved it. Over all it was a battle to over clock and I am sure that better RAM would help but here goes.

These tests were run on SS Phase, with a no boot on Cascade because of cold bugs at those temps.

This is a very nice board and I did OC better than on earlyer boards with the same CPU's.

very easy to work with :)

Nice little clocks there Buckeye. Yeah, at 4.7GHz max really might be that chip's internal max being used and all. Most of my posts will involve TEC or liquid cooling of some type. Got a Boreas to throw on there a little later this week.

Lasty, the P55A-UD4 is a beefy little performer especially for the price. You could probably get higher. But, for a quick easy 1GHz overclock, that's the perfect level for stability and less wear and tear.

Thanks, I really did not wish to have to throw so much vcore on this chip but it was the only way to get it to clock up. The P55A-UD6 can supply the power thats for sure. Hopefully a better chip will make a dif and get this rig really moving with colder temps.

I had a lot of stability issues as I clocked up and tried 3 different sets of RAM but that didn't help much. I think I was RAM limited but I am not sure. These were just 1600 Dominators so nothing fancy, tho they have clocked very well at times, on my 920 I had them over 2000mhz but that might have done them in LOL.

I have allways wanted to give a Boreas a try and see how it performs, mainly for a 24/7 rig.

Yeah i think i can do better, but i'm not familiar with all the right voltages etc. Also my temps are maxing out a bit (upper 70's).

Can anybody give some indications of safe voltages for a 24/7 4ghz clock with an i7 860 & memory at 1900mhz? I'm now using around 1.35 vcore / 1.30 vtt / 1.05 pch / 1.8 pll, and its not 100% stable..

Hey guys, I had a chance to play with a P55A-UD6

Both very impressive boards. very nice runners

Nice little review there. And, you got all that with dry ice and acetone? I guess phase would offer very similar results. I saw some comments that a cold bug presents itself at some point on the 860/870.

I'm about to see how the UD6 does on dual GTX295s. Predicting some interesting results versus the X58 setup.

is it safe to enable LLC guys..?

Wll with the ES chips I have they have major cold bug issues. I believe Punx's is a retail chip and those are much better from what I have seen.

That makes sense, Buckeye. I rarely get any retail chips which would be nice on occasion. But, I have also been given some leaky ES chips which a more experienced LN2 friend used to drop some records.

Speaking of leaks, here are a few pics of the P55A-UD6 demo system from Intel's Infernalan up here in Washington state. While I like the stream lined appearance of an integrated liquid cooling systems, you're stuck using it till you move over to something new. The external Koolance Exos 2.5 comes in handy since I can move it over like with this customized Antec P183. Hope we can get one with a black interior chassis for future events. :o

http://www.xtremesystems.org/forums/...&pictureid=931

I had the Kingston HyperX 2133MHz Dual Channel at 2225MHz 9-9-9-30 which pushed this 870 in to really hot territory. Coupled with the GTX295, it played everything over 60 frames on a 1920 x 1200 monitor.

http://www.xtremesystems.org/forums/...&pictureid=930

I'm going to give this latest BIOS a try for some crazier frequencies. It's SuperPi stable when I push more than 4.3GHz, but 3D is a little sporadic. Some of the Auto settings aren't cutting it. Maybe drop the Uncore a bit today and see what happens.

http://www.xtremesystems.org/forums/...&pictureid=929

By the way, PugetSystems.com are currently offering the P183 and P193 cases all customized with windows and integrated Koolance systems. The P183 costs something like $140 to $150 with the window. Good prices.

Nice looking setup.

I should give Water Cooling a try and I am getting tired of SS Phase 24/7

Alright, since this machine is water cooled and can dissipate 1400 watts of heat, it must be pushed. I flashed the system with the latest (GBT USA listed) F5 BIOS which yielded some interesting results. First, the Auto settings were more stable to 4.1GHz, which isn't much more than the F3.

However, the F5 quickly and easily accepted 4.2GHz with manual CPU, PLL, and VTT voltage settings (set just a bit more than where it should be when at this frequency in Auto). The CPU voltage was set to 1.42 volts. CPUZ and a couple utilities confirmed that there's no V-droop at these frequencies.

Here's a screen shot of the nice performance gains. The Single CPU test in Cinebench just broke 6,000.

GA-P55A-UD6 - F6 is latest BIOS.

You're right. I grabbed it off the GIGABYTE-USA site which I assumed would have the latest. *de de deeeee* And, the latest on file there is F5. Still is at this moment...grrr....Guess I should have looked at Taiwan's latest first. Thanks a lot for pointing that out - have to start all over. :D

Nope mate,links are still in this thread.:D

My OC:

Got a P55A-UD6 this week, finally had some time to play with it this weekend. Solid board so far :up: I dusted off an HD4850 CF setup to test out in the board and while I wasn't too excited about using the old cards, either they aren't as horrible as I thought they were or 1156 just makes them a lot better :) Either way, I ran some benches on it this weekend and figured I'd share...

WCing on the proc, stock 4850s with single-slot coolers using CCC for OC.

http://i10.photobucket.com/albums/a1...32m_752265.png

http://i10.photobucket.com/albums/a1.../wp_171079.png

I didn't have too much time, but I decided to drop the SS on real quick (which seems to be getting weaker by the day). This proc has real big diminishing returns >4.9GHz cold or not, high Vc or not, so I just took it easy on the SS and CPU and did some quick, light benches at low Vc :)

http://i10.photobucket.com/albums/a1...d6/1m_8250.png

http://i10.photobucket.com/albums/a1...32m_732219.png

http://i10.photobucket.com/albums/a1...am3_328973.png

For the record, I was using F5 BIOS that it came with. 220BCLK is about max on ambient cooling (same as every other board I've tried this proc in). On the SS, I to got it up to 235BCLK easily, but didn't try very hard for more. The proc hasn't gone past 240BCLK in any board, so it's almost guaranteed the same here.

As I have more time, I'll put a little more effort into the benches, but it's off to a good start :up:

i've been waiting for a while for this thread, please help me with an answer, does anyone who uses p55a-ud4 or ud4p onboard sound realtek alc889a on analog 5.1 mode on the realtek console manager have rear speakers or side speakers active in this configuration?

I had various 5.1 speakers set up on many an ALC889A. Are you having problems with your's or something?

I can easily discern the differences between the 889 and 889A Codecs since I run many full ranged audio and video benchmarks. Full range video games benefit as well.

I've updated the post with some Review links slowly coming in from the battlefield. We should soon see some USB 3.0 benchmarks as the devices go out to reviewers. Many of us are still waiting for a more polished, ready device. *Wink*

I've had a gigabyte ep45-ud3p v1.0 with alc889a where when i chose a 5.1 channel speaker configuration on the realtek sound manager with the latest drivers installed i had side speakers active and no rears. My brother owns a ga p35-ds3r with the same alc889a and he doesn't have this issue , he has rears when choosing 5.1 config not sides, so thats why i wanna know if ga p55a-ud4 has this issue or not( i wanna buy it but i need this issue cleared first) It was the same no mather which SO i installed for my ep45-ud3p
In the atachment u will find my brothers ga p35 ds3r realtek manager and with red markings is how it was on my ga ep45-ud3p

Trouble shooting these type of issues can be frustrating. Are you and your brother using the same Windows operating system? The speaker package should theoretically be just fine. However, some can give you a headache due to their design. I assume you've tried different drivers just in case to rule out any OS bugs.

Otherwise, I haven't encountered any issues here using some basic Creative and Altec 5.1 speaker packages on the P55 or P55A motherboards that have the ALC889A Codec.

yes i've tried everything, around 6 driver versions, and it was the same on win xp sp3, vista x64 sp 2 and windows 7 x64 :down:, i ve even bought the creative x-fi mb for this board (still no change), something for a guy living in Romania is kind of hard cause u just can't ( my country isn't listed when you try to buy the x-fi mb activation code and after mailing their support team they answered that this fact won't change in the near future). I have a logitech g51 sound system.
Ok i will buy this board hopefully i will not have this issue:shrug:
Why does this issue bother me?? cause most of the sound codecs don't know about sides, they send the signal to the rears in 5.1 config, so u can imagine how nice is that:), otherwise i would just plug my rears on the sides imput and get over it.

The drivers you both are using are probably very similar if not exactly the same. Try configuring your software exactly the way he has and see what happens. It could be the speakers aren't playing well if they're tandem, but I doubt it. It sounds more like a configuration issue. The last resort is that the integrated audio chip is having issues.

If I read your post right, you tried using a discrete X-Fi audio card. If that didn't work, then it definitely narrows it down to an incorrect software setting and/or speakers not compatible with 5.1 for some odd reason.

Neah is not a card is just a software from creative for onboard realtek alc 889a owners to act like an X-fi , u got it on youre motherboard driver cd or u can download it on gigabyte webpage and it's only for 30 days.
http://www.gigabyte.com.tw/FileList/...090106_xfi.htm
http://www.gigabyte.com.tw/Support/M...ta+x86+(32-bit)

Ok, I understand now. Yeah, I've seen those downloads available for some of the boards. I was under the impression that an X-Fi capable board will have the aluminum little X-Fi tag on the audio chip like on some of the other brand boards.

One thing also nice about upgrading to the P55/P55A boards is that the LGA1156 processors are much quicker than the LGA775 series. You should be able to find some pretty good deals.

anyone else get a nice buzzing noise from the VRM area? Under load mine is LOUD :(

Thinking I just got a bad board... can anyone comment?

does anyone know if ga p55a-ud4 has both sli bridge and crossfire bridge conectors included?

I can’t get my p55a-ud3r to post. It gives me several short beeps in a row and a long beep at the end and restarts. If I remove the RAM it doesn’t give out the long beep at the end but continuous with the short ones but with pauses and it doesn’t proceed to shut down as before.
My zalman zm600-hp won’t boot the board at all, my corsair vx450w does though.

Things I have done:
Tested the PSU and graphic card in another pc with no problems.
I tried both PCIe slots. Tested with another graphic card.
Tried 4 sticks of RAM in different slots.
Cleared the CMOS by removing the battery and later on I tried the Clear CMOS jumper.
Checked the socket, reseated the CPU- several times.
Put it inside a case and then outside on the cardboard box.
Tried it in another wall socket in another room.

Things I have not done:
Tested the CPU on another board (don’t have one)
Tested another CPU on this board (don’t have one)
Tested the RAM on another board (don’t have one)

Specs: Xeon x3440, Gigabyte p55a-ud3r, 8800gts 320mb + ati x1900gt (not at the same time), 4x1gb 1.5v A-data with hynix chips, Corsair vx450 + Zalman zm600-hp

Any ideas? :shrug:
Should I RMA? I’m not sure if it’s the CPU or motherboard, but it’s probably the motherboard? I know that the x3440 isn’t on the supported CPU list, but I have read that other people have not had problems with it, including gigabyte boards.

Mine only came with an SLI bridge included.

Had a chance to bench a 870 ES CPU on the P55A-UD6, was not a whole lot better than the 860 ES. As I compared this 870 ES to other retails I can see this chip requires a fair amount more of vcore as the OC is upped and still does not like extreme cold very much.

All of this was done on SS Phase and as I got to around 4.6ghz it was really stressing the Phase unit because of the vcore need to boot and run benches.

Cascade operation was just to painful as it seems to CB not to far past what Ss Phase could do so I would have to shut down the 2nd stage to get it to boot, then fire it back up and heaven help you if you had crash and had to reboot. While I was at -100c it really didn't seem to help much and this chip was very unstable so I stopped Cascade operations.

If this seemed like a good chip I would have gotten some DICE but I didn't think it was worth the cost of DICE to even mess with this CPU.

So here are some screens of how it all went down, starting at 4.0ghz and going as high as it would take me.

Final notes:
I compared my results with the AnandTech results seen here
http://www.anandtech.com/GalleryImage.aspx?id=7111

I see that they are usin a few different RAM timings than I have so I will try and see if I can get the ones they used on mine and what the results might be. They do not seem to show there RAM speed tho. I did take mine up to 2000mhz but it did not seem to help so I went for tighter RAM timings which did help me out. My chip would simply not boot at the vcore they showed :(

I haven't seen too many folks breaking the 5GHz barrier with the i7 860 or 870 unless it was a "nice" chip. Do you only have 1600MHz DDR3 memory on hand? Or, are you just using it while pushing the CPU to its limits?

Not sure my extra cooled liquid cooling system can quite get my 870 there or not. Still, 4 to 4.3GHz for the regular folks who don't get too extreme is a pretty nice performance gain. One of these days, I'll get a hold of some decent Phase cooling.

Yeah I am not sure what is going on with these CPU's I have tried. I see boostedevo above was hitting 5ghz with 1.5vcore, mine would not even boot unless I was close to 1.7vcore which was just to much load for SS Phase.

Sometime wrong with the ES CPU's or board, I dont know, maybe its just me.

I did get a Dominator GT 2000mhz RAM kit were I could really tighten up the RAM timings and thats what I used on these last runs, but getting to 2000mhz was not easy, where as on my other Dominator 1600mhz kits I could get to 2000mhz easy but could not get the RAM very tight.

So in the end of all this I am scratching my head going crappy ES CPU's or something wrong with the board, I don't know. The more I see what others are doing I am begging to think something is up with the MB as 2 ES CPU's now are doing pretty much the same thing.

I'm having trouble getting the BCLK frequency stable over 215 with the rig in my signature, I'd like to try upping the QPI/VTT voltage but unsure of relatively safe levels for this? any suggestions? thanks.. :)

By "Tried 4 sticks of RAM in different slots", do you mean you tried one stick installed at a time? I'm wondering if one of the sticks is bad, or perhaps the memory and board aren't compatible. I'm sure you got them in the right slots noted in the manual, try the steps below.

Try each stick and see if you get post. If they're good individually, keep adding a stick at a time. If the 3rd or 4th gives you error, set the memory timings and voltage manually with the first 2 installed. Then add, try adding the 3rd and 4th sticks again.

If you can't get them going at all, it'd be nice to try them on a friend's system or maybe have the local PC store try the RAM. It's a pain, I know, but they'll usually do it for free.

Let us know how it goes.

My zalman zm600-hp won’t boot the board at all, my corsair vx450w does though.

Things I have done:
Tested the PSU and graphic card in another pc with no problems.
I tried both PCIe slots. Tested with another graphic card.
Tried 4 sticks of RAM in different slots.
Cleared the CMOS by removing the battery and later on I tried the Clear CMOS jumper.
Checked the socket, reseated the CPU- several times.
Put it inside a case and then outside on the cardboard box.
Tried it in another wall socket in another room.

Things I have not done:
Tested the CPU on another board (don’t have one)
Tested another CPU on this board (don’t have one)
Tested the RAM on another board (don’t have one)

Specs: Xeon x3440, Gigabyte p55a-ud3r, 8800gts 320mb + ati x1900gt (not at the same time), 4x1gb 1.5v A-data with hynix chips, Corsair vx450 + Zalman zm600-hp

Any ideas? :shrug:
Should I RMA? I’m not sure if it’s the CPU or motherboard, but it’s probably the motherboard? I know that the x3440 isn’t on the supported CPU list, but I have read that other people have not had problems with it, including gigabyte boards.

You probably won't run in to any issues if the QPI is kept to 1.7V, or just a hair above. VTT can take a little bit more too. I've only had to add a little QPI when pushing the memory. And, most the voltage has had to go to the CPU. Give it a bit and see what happens. :)

On ambient, 215BCLK is really about the benchable/stable limit (at least on all the 1156 boards I've tried). On WC benches, I am always 205-212. 1156 BCLK really only opens up on cold so if you're running ambient cooling, I wouldn't force the issue too much with voltage because you probably won't be seeing 220+ BCLK for daily use no matter what.

The 860 is much better than the 870 that I had, but there are still big diminishing returns near 5GHz. SS will get close to 5GHz benchable, DI is only good for maybe 5.1-5.15GHz benchable and LN2 can bench ~5.20-5.25GHz. 5.25GHz @ 22x is nearing 240BCLK and I have never been able to get past that mark.

One thing I noticed (mostly out of necessity as SS = weak) is that a bit of finesse with voltages goes a long way. I jammed the 860 with voltage when I first got it and noticed not long after that I was just running WAY more than it needed and it did in fact seem more stable with lower voltages than I started with. Some combinations that were too high just crashed the second I started a bench.

On the benches I did today, 1.46Vtt was the highest I ran (for the 231 BCLK bench). I am usually even lower than that on WCing since the high BCLK isn't a factor (~1.30-1.36Vtt). Either way, I don't think it's possible to run more than 1.56Vtt on any 1156 board/proc unless something has changed since I last looked. If you set it higher than that, it likely won't even POST.

Anyway, I benched a bit more today with the SS. 4850CF is working quite nicely in this setup :up: Cards are on their stock single slot air coolers. Mem on these runs are 2 sticks from a Dom GT 7-8-7 kit. Set to 1.66V and never budged from that voltage (why it's CAS 8 for anything >1100 ;)).

This 32M wasn't on a clean boot because I didn't think it would even finish. I was just testing the waters, but since it did complete, I said "that'll do", screened it and moved on :D

http://i10.photobucket.com/albums/a1...32m_730578.png

4.6GHz+ with HT is just way too much for my old SS, so no real shot for 29K+ :(

http://i10.photobucket.com/albums/a1...3d06_28654.png

http://i10.photobucket.com/albums/a1...3d05_40352.png

This was a bit of a half-a$$ attempt on 03...didn't really do anything with mem and had to lower the card clocks since it was artifacting like crazy. I'll give it another shot soon.

Yeah, I tried 1 stick at a time, with all the sticks. It's in the "Memory Support List" with matching ICs etc. But I don't think there is a problem with the RAM. It would give a different signal, like long beeps compared to the ones I’m getting. I would be grateful if anyone could try to boot their board with no RAM inserted, and tell me what the beeping sounds like.

I'm guessing it's the PSU, motherboard or CPU. I tried a corsair cx400 PSU but it gave me the same error, but I think it's based on the same seasonic platform as the vx450 so I still haven’t ruled out the PSU.

Just a question, I use to own 2 P55 boards (Not the revised editions), the UD5 and UD6 and I found the BIOS to be extremely buggy. Believe me I'm a huge Gigabyte fan and I'm still am, but I was wondering if anybody noticed these issues with their boards:

Installing two or more DVD drives will cause the screen to hang at Boot DVD/CD screen
When overclocked, the reset button does not work properly, instead when pressed you must wait for at least 3 seconds and the machine turns off instead and turns back on after a second. WTF?
When using Intel Turbo Boost when your RAM is set to 1600Mhz or over, the CPU will stay at a locked multiplier (My 860 ran at 2.9Ghz all the time and will not go over and Speedstep will not work)

Thanks boostedevo

I think you have a much better 870 than I do, you can get it to run at a lot lower vcore than I can. Mine had a date writen on it with a black felt tip pin that went back to July I think it was, so it had been around the block a few times.

When I look over at HWBOT the vcore that I used is a little bit, or even higher than what others are using. I never went higher than 1.4QPI/Vtt, some I had talked to said keep that in the 1.3 - 1.4 range. I might try going higher and see what happens.

I also had some strangeness with the BIOS and booting with 22 multi and 200 Bclk, date would change back to Jan 1st 2009 out of no where.

When I finally took the CPU out yesterday I had 2 pins in the socket baddly discolored.
AU38 & AU39
SA_DQ[60] AU38 DDR3 I/O
SA_DQ[61] AU39 DDR3 I/O
Not sure what was going on there, condensation or something else, but it seemed odd that these two pins would be discolored from condensation and the socket was clean with no stains at all. Looking at the CPU itself those two pads are slightly discolored also. I don't know maybe user error there but I just have not seen condensation issues like this before.

A few bench results from my P55A-UD6 review. I'm working on max air OC still, and LN2 is coming very soon.

sno.Icn !!! How goes it? I've been wondering what happened to you and the rest of the OC bunch from the GBT OOC event. Glad to see you're alive and kicking. Your results are pretty much on par with everything I've seen on air. It's tough finding that max-max on air if you don't know the threshold of your air cooler. One second it seems fine and the next, it's screaming towards 75C.

Chrono Detector - I've experienced something similar to that 3 second pause. Most the time its from a not-so-stable-OC, or I got too impatient before windows fully loaded. When I'm overclocking the CPU, I usually have Turbo disabled. Otherwise, I haven't seen that locked issue pop up yet on the P55A.

Euxinus - That Zalman 600W should be plenty of power for that system. Even though the board is beeping and restarting, making it sound like it's close to booting, it could just be the board. If I had your system in front of me, I'd still take the RAM down for testing. The only times I've experienced those beeps were due to the 12V aux 8-pin wasn't plugged in and/or bad connection - CPU wasn't being detected properly. You do have a Xeon plugged in there and I can't help but wonder if the BIOS can't see it.

The zalman won't boot the board at all, I have read that it had problems with the gigabyte x58 series too.

http://forum.zalmanusa.com/phpbb3/vi...c.php?f=9&t=73

With the corsair PSUs the fans and the lights start up at least. Yeah, my first thought was that there was something wrong with the 8pin. I don't think it's the RAM, since even if I remove the RAM and have nothing plugged in the RAM slots, it still gives me the same beeps. Usually when there is no RAM plugged in, shouldn't it give long beeps compared to the rapid beeps I’m getting? I get the same kind of beeps with RAM or no RAM, the only difference is that it shuts down after the beep cycle if have RAM in. How does your system act with no RAM in? I don't have any convenient way to test the RAM as my other 2 systems use DDR2. It will probably cost me if I go to a shop, so I'm saving that as a last resort.
It might be that the CPU isn't supported, but I would probably be the first one to not get it to work (or??)

Oh, and thanks for trying to help btw.

Any time, Euxinus. I was going to suggest looking around to see what BIOS people were using with that particular board and chip. While its a pain, hopefully that's all it is and just needs updated.

I'm sure there are some elites on XS that have something similar if not exactly the same. Good luck with the hunt.

---

Yeah, as with all h/w, some are better than others. This 860 runs circles around the 870 that I had, just luck of the draw.

As for Vtt, you might even try lower than mentioned before too (like 1.24-1.30) and see what happens. I know it seems counter intuitive, but 9x out of 10 for me on 1156, less is more when it comes to voltages. It may very well be this particular proc, but even right this second, I'm at 200x22 (WCed), 18x uncore, mem at 1000MHz 7-7-6-18 and using only 1.26Vtt. Granted, I'm not benching or playing games and it might die in 2 seconds for those, but it just goes to show that it doesn't need a boat load of voltage to even just get it boot with everything running pretty hard. One other thing that you could do is to try booting with all voltages on AUTO (except mem) and use EasyTune to see what they are if it's a successful boot/OC. Then use those voltages as a baseline to work from. Sometimes leaving everything on AUTO will let it boot where I hadn't been able to get to boot myself :p:

I'm fairly sure that the only times I've had a date reset in CMOS like that was due to memory (or memory controller) being ticked off. If that happened to me, I'd be looking at mem speed/timings/voltage, Vtt and maybe Vpch.

It doesn't seem like you are even close to the ballpark with voltages or clocks to be having an issue with anything. I'd lean towards condensation, maybe they were compressed together a little bit or maybe there is an issue with the proc itself if it's been around the block that many times :shrug:

On air. This boards makes OCing super easy. It's also a pretty decent 860. My last 860 did this barely on LN2 :rofl:

I'm going to try i5 now, and LN2 very soon.

*Also don't look at the voltage :p

I hope to be joining you guys this weekend with one of these boards, ordered the P55A UD6 board. I should get it tomorrow, also waiting for an 1156 water block to arrive. Looking forward to being back on a Gigabyte board.

Finally got the board a few days late due to weather. Just got home from work, hope I will have time to play with it tonight. Did a short LinX run at 4ghz. This replaced my evga ftw board which I started having problems with.

http://img132.imageshack.us/img132/6960/4ghzud6.png

such a shame that @ least on p55a-ud4 with i5 750 when u enable c1e and eist when overclocking and u manually choose voltages and memory settings, only Eist is still working, drops the multi from 20 to 9 in my case, c1e( voltage reduction) doesn't work :(

i would like to know about that 2, cause the purple zone goes from 1.23+ to 1.6 when it gets red? so what's with the big purple zone?

Another short LinX run at 4100mhz with LLC enabled, load vcore was 1.296v.

another at 4200mhz 1.312v idle 1.328v load. This board is doing better so far than my evga board, requires less vcore for the same clocks.

can you post a bios template?

Hey all

I have BIG problem with my P55A UD6. I can't OC normaly. On my old Asus P7P55D, i can run 4300MHz (Prime stable) vcore 1.44v, 1.28 VTT, 215×20 and 4726MHz for validation and MAX BCLK was 230 on 1.34 VTT. All on H2O!

But with UD6 i can't run 200BCLK. If i set VTT above AUTO i get BSOD on higher BCLK.
20×200 on 1.44Vcore, 1.34vtt is a no go :mad: On Asus i can run 20×200 on 1.3Vcore, 1.22vtt

Is there any settings in BIOS to set that i overlooked them? Or is my board broken?
Can someone please post some BIOS settings?

@cole2109, was able to boot fairly easy at 4800mhz by changing the advanced clock control settings to 900/900/50 and giving it some vcore and vtt.

A few questions for the group.
I have a P55A-UD4P with F6 BIOS and really liking it so far. I'm OC to 3.8GHz and will be shooting for 4 or 4.2 soon.

Per the manual, I understand that if SATA3 and USB3.0 are set to PCIe Gen 2 then the primary PCIEX16 slot will run at X8 and I can verify that with GPU-Z.

Using a Radeon 5850, am I being limited by the X8 bandwidth? The manual says that I can disable TurboSATA3/USB 3.0 in the BIOS, but mine is defaulted to AUTO with no option to change it, it just skips over that line when tabbing.

So far I tried disabling both the GSATA Contoller (SATA3) and the USB 3.0 option, they're separate lines and disabling both still leave the TurboSATA3/USB 3.0 line on AUTO and my PCIE at X8.

Hard drives. I'm using a 150GB Raptor and a 500GB WD. Should I leave the PCH SATA Control Mode on IDE which is the default or change it to AHCI?


Thanks for any suggestions!

I don't think you're being limit by 8x at all. I'll bet once you get 16x going, if you bench both ways, you'll see no difference.

As for the locked out setting, I was on F5 and just updated to F6 to check, but my options for changing Turbo/SATA3 are unlocked and selectable. I tried plugging things into the GSata and USB3.0 ports, changing all kinds of config options trying to see if something would make it unselectable, but I can't duplicate your problem.

Have you tried resetting CMOS and see if that opens it up?

I was thinking that, but it sure would be nice to have the option to run at 16x.
I guess I'll try the CMOS clear and see what happens!

Boostedevo is on the money. In the most extreme of instances, such as filling every possible port and slot with USB 3.0 and SATA3 drives while pushing SLI, have I seen the ports slow down a bit. But, let's be realistic. How many folks are going to be running a video game while saving/writing to their USB3.0 and SATA3 devices? You'll have to create a rather unrealistic setting. :)

As for 8x and 16x benchies, the performance hit is pretty minimal. And, that was while running another semi-unrealistic build - dual GTX295s. o_O The power consumption is ridiculous. I'll stick with dual GTX285s.

hi guys.,just want to ask.,is it safe for gigabyte P55-UD4P.,4Ghz OC with 1.36vcore.,1.27vtt.,and already change the CPU socket to LOTES bracket for 24/7 use..?

Very safe! Nothing to worry about! Even the old sockets won't show any CPU issues at 4GHz 1.36vcore. You'll have to go much, much higher than 1.45vcore before anything starts to show up.

tq temujin..:up:

Has anyone used the new clarkdale on theses boards, in particular the UD4P?
Im having trouble getting high bclk
Does any one have any newer bios for this board that work for clarkdale?

Check GIGABYTE's Taiwan download page for the P55A. I think they have a few new ones that I need to go up on the original post. Otherwise, I was able to hit 4.2GHz with the Core i5 661 with Auto settings. I'm predicting similar maximum overclocks compared to previous Core 2 Duo, but not the same gained increases.

Thanks for the heads up Stasio! :) I've updated the very first post with the BIOS links from the Taiwan site and included the downloads page for those who have a motherboard not listed. Going to try a new BIOS on the P55A-UD6 and another new board ASAP. *waits for the shipping courier to show up*

WOW great job! I want to try one of these new chips.

I will be switching back to my p55 tonight, seriously considering getting the 660 or 670.

Where did you get this board? I haven't found it in the US yet.

For the forum: is Gigabyte planning to bring this to the US?

Thank you.

i think the IMC in i5-750 is better in terms of memory overclocking and its performance.
or may be (but i doubt it) it's just my motherboard's bios is not optimized for i5-500/600 series chips yet.
as of now, for ram overclocking i can go to as much DDR2133 when i use my other ram kit with 2133MHz XMP profile,
but fully stable at only 2100MHz, this's about it on my chip, other chips IMC could be better.
however, right now memory timing in Windows is still a mess.

I have my answer from Gigabyte Support:

unfortunately the UD3R will not be carried in this region

So it's not coming to the US.

I'd not like to hijack this thread, so if any of you have any suggestions as to a reliable UK supplier of the P55A-UD3R, please post in this thread.

Thanks

Guys, if I'm on a budget and am adamant with Crossfire, should I stick with the P55A-UD3? I save at least $40 by going with that solution. I'm not convinced that the extra capabilities including SLI on the UD4P is worth the extra money. I'm just looking for a board and RAM combination such as the G.skill Ripjaws to increase the odds that I'll get a 4ghz oc with the i5 750. So what should I do?

^^ Do not use the UD3 especially doing Crossfire, you will get 4x/4x only and that will bottleneck your performance. Your better off getting the UD4P for better results. And I heard Gigabyte's P55A boards when US3 and SATA3 enabled you will lose functionality of the second PCI-E slot and therefore SLI and Crossfire will not work. WTF? So there is another reason to avoid Gigabyte's P55A line.

I think I discussed this with you in another thread. I think Crossfire will work, but ultimately performance will decrease if USB 3.0 is used. I think it'll be fine because I'm not looking to benchmark the machine. I don't think performance decrease will be greater than 25%. I can live with it. The boards seem to have good reputations and that's why I'm somewhat locked into it right now.

For those of you with the P55A-3P and -4P: can you turn off the TPM chip in BIOS?
