Meaning F5 and F5B are the same age...

B stands for "Better" so it must be better.

[BiTsCrEaM]

Well, I am curious as what the actual difference between the two is.

[TiTaNiUm]

Lovin this board...

edit little slow on screen, had to set up account;;lol

[GAR]

Must be the same bios, dated the same. I agree, this has to be the best board i have ever owned, and ive owned many $300+ boards that have not come close to this!!! Gigabyte has a huge winner with this board!!

[big poppa pump]

Damn! I am loving this board. Currently Prime testing @ 510x8 with my E8500. Been running for the past couple of hours. Will post some screenshots and specs when I am done running them.

I thought the B stood for Beta. ?

huge numbers congrats

I have updated the second post with all the reviews I found (but not very much )

review of this stuff

http://www.ur-hardware.com/Memory/G.Skill-4GB-PI.html

I ordered a set about an hour or so ago UPS next day for friday. Maybe it'll help me with my blend stabilty issues.... but i dont think so.
This is whats happening, maybe yall can shoot me some suggestions.. Ive tried both of these gskill 1066 4gb (2x2) kits.
Running them at 1000 (lower than the rated 1066) and the gskill ddr2 1100. i cant pass blend for more than a few hours.
I've tried voltages from 1.9 to 2.3. cas 5-5-5,6-6-6, 7-7-7 and auto. I've loosened all sub timings tremendously.
I've tried everything. It will past overnight memtest86 but fails windows HCI memtestPro after a few minutes.
Fails OCCT. Passes prime small fft. I am currently at 8x500 with this quad that is small fft stable at 9x500.
Is it a memory issue or board high fsb stability issue? It's driving me crazy. It will pass blend and windows HCI memtest if i use a single stick.
Both sticks have ran separately for hours even overnight on both programs with 0 errors. Please help so i'll stop buying higher end memory lol.
I ordered the gskill ddr1000 4-5-4-12 as well but they shipped me the wrong stuff. Waiting on RMA to send the right stuff out.
I have $500 worth of Gskill in the mail

I have this Board now for 2 Weeks and tested it (imo) very extense during this time with lots of settings. I really enjoyed this board so i thought i write my expression down.

My System: Q9550, UD3P, OCZ Flex 9200 2048mb, GTX 280 702-1404-1161MHz, Vista 32 rig

10.20.2008:
Dang, 11:34 i jump into my car to drive 100 km to get my new CPU. While i was in the shop and chatted with the chief 0C there he showed me that UD3P and said that this board has a awesome performance, not to mention the price. I originaly thought about a Asus MF Formula II but with the performance in mind i thought what the heck and i took the board with me. Wnet home and downloaded bios f5a which i used then for a while.

System runs @ 3GHz with 1,1v. Poor Latency but awesome low Power Consumption.

System now runs @ 3,4GHz with 1,19v. Average Latency but stable with DDR2-1200MHz. Read: 8923 Write: 8350 Copy: 8350 Lateny: 56,1ns. First thing i notice: The Bios scales very good the gtl ref values. At the start of your 0C just set all voltages to the normal rating. Fe. if you have the vtt at 1,2 and the CPU and NB GTL refs at 0,76v you will notice that with every step you increase the vtt he will automaticly adjust the GTL refs with the 0,635 multiplier. So my estimated 0,889v for 1,4v vtt was automaticly set to 0,886v ref value. So for 0C starters this board helps you a lot to keep a Quad stable. The board is also able to run high FSB with low voltage on the mch.

System is becoming unstable at FSB 450. After some advice i switch back to Bios F4.

System now runs @ 4GHz with 1,344v. Lower Core Voltages @ FSB 471*8,5. Latency is good the system still is able to run a tRD of 7 while at DDR2-1178. Read: 9895 Write: 9857 Copy: 9248 Lateny: 56,0ns. All Benchmarks and stress tests are passed without errors.

System now runs @ 4,25 GHz with 1,383v = FSB 500*8,5. System is getting unstable. Even giving lots of vcore and vtt won't manage to keep the system under control. So we go down one half multi and loosen the core voltage a little to 1,36v with 1,38vtt and 0,881v for the GTL ref. MCH core voltage is set to 1,3v. The system now seems stable all benchmarks are passed and stress test showed no errors. So i switch to a memory multi which will put more stress on the mch controller and the system itself. We're now at 4GHz @ FSB 500 with DDR2 1250 @ 6-6-6-18 and a tRD of 8. This leads to astonishing Read: 10182 Write: 10528 Copy: 9966 Lateny: 51,3ns. Pretty darn good for a Quad on a P45 imo.

After having the system for a few days at the mentioned settings i thought i push it a lil more. I gave only 0,01v more core and upped the FSB to 510*8 = 4,08GHz with DDR2 1275 MHz (6-6-6-18 tRD:8). Ok now i get really close to what i have been looking for: Read: 10321 Write: 10747 Copy: 10006 Lateny: 50,4ns. But the system is getting unable to pass Prime 95. So i up the core voltage to 1,392v. This does the magic. Everything works now, Benchmarks and Stress tests can be all passed again. 3DMark 2006 produces 20019 points.




Maybe i can do a little more. I up the FSB to 515*8 and i set the vcore to 1,41v and a vtt of 1,6v. But the system now really becomes totally messy (prolly the tRD thats to low or the rams speed to high). I quit 0C for now and fall back to 500*8 at 1,3442v, vtt 1,36v, mch 1,3v and DDR2 1250. And thats a pretty stable setting. Passed various 6h prime tests as well as OCCT and the intelburntest. 3D Applications all work fine.

I will try later on to get to a super stable setting above 510 FSB but now i have no time. But i can say this board rox. The mosfets keep really cool compared to the Asus Boards i had until now but on the negative side i must say if you have this board running near its limits you hear the mosfets whistling. Well besides that i have sumed it all up. This board along with its default bios pumps the out of 45nm Quads if your ram works along with it.

Thanks for the post. I havent been able to post when adjusting gtls. I did it the way you did and now shes runnin. Maybe that was the key to my blend stability. I will report back in a few hours.

[Elektrosadist]

wish you luck. all my voltage settings are under load. i will post on the weekend a stable fsb 500 template and a et6 ss. i'm tryin to lower my memory latencys now a little while remaining @ DDR2 1250.

I've pumped out some ok mem latency and bandwidth with this board. Cant wait for my 4gb of gskill 9600 tomorrow. It may be a good day thanks to you (knocking on wood). I dont get BSOD's or any issues other than blend and windows memtest tellin me i have issues. Now so far after your gtl config im an hour in to blend. lately its been erroring in a few minutes. Sometimes made it to 50 minutes but hardly ever further. I cant wait to bump the multi back to 9 and run 4500 24/7. Will post back later.


I've asked plenty of times in this and the other UD3 threads about the GTL's and according to templates everybody seems to leave them on auto. Never got any replies to my questions. Adjusting them has always helped on my other boards, Auto never worked. Again i'm glad you shared your scenario and settings. Maybe were on to something now. i foresee much higher clocks.

[nugzo]

2 hours in and good to go. Gonna up to 9x and tighten timings.

[nugzo]

I know this is off topic but i dont think it'll hurt anybody. I just up'd to 8.5 multi and my everest freaked out. Anybody ever seen this?

[godto]

Nice OC but your temp on here is 80 ... is that save ???

what the max temp on this Q9550 ??

I ended up keeping the G.Skills, they max out at about 545mhz but they are rock solid on this board!! better than Corsair. I installed the F5B bios and i have a new overclock!!!

[Sgt_Strider]

How well can the UD3 series overclock when all the memory slots are filled with DIMMS (max of 8GB on 4 DIMM slots)?

[MacClipper]

max of 8GB

max. is 4 x 4GB actually for P45, I would like to know too but don't think there are many such users around.

My second 4gb kit will be here today. I'll let you know this evening.

[Elektrosadist]

@nugzo: if it fails after one hour or more in a stress test you have enough vcore and its most likely that you need to up the vtt or the mch a lil more to get stability. Or you keep it the way and first try your luck with the gtl refs and move them one step up.

I also had that weird everest thing at some points. I also noticed when not using enought voltage on the mch the display would go black after a while except for the taskbar. Lol this OS and board shows me errors which i have neva had before while i was using faulty 0C settings. But good thing is when you notice stuff like this you know that u pushed it too far. ;-)

[Nocturno]

Indeed F4 bios is better for quads. With a Q6600 can boot to windows 475FSB with only 1.30v VTT and with bios F5 its very hard to boot at all.
