Enable PLL Overvoltage.
Check RAM timings.
Lower RAM timings to 13.33
Try raising vccsa to 0.975v or VTT to 1.1v.

With the B3 chipset and F3b bios does PPL overvoltage still cause boot issues?
will be a bios that corrects bclk to 100MHz?
Checking the settings immediately raised tensions vccsa and vtt, I will know that went well
Yes kuziu, the cpu on UD4 needs more voltage for being stable then on Asus board. I can not run even 3DM06 at 5000MHz with 1.42v (1.45v is stable) and on M4E I could get 5GHz 1.42v 24/7 stable and 1.4v benchable. Nothing weird I'd say.
It is noticed that the board needs more vCore than the competition, but the album as a good price is, and even ASRock P67 PRO3 held to better processor with high frequency, the msi GD65 processor clocked at 4.7ghz need about 1.4V, and nothing more, and even here 1.475V is not enough, all the time is an error in linxie, and I play it I get a bsod 0x7E or 0x1E more vCore, I can not give, because I killed my CPU, now test the 4.5ghz with 1.35V vCore Bios, and lynx no longer crashes errors also do not know what's going on, once stable, then the same errors and bsod
Sorry, it's not that easy to understand you, though.
What do you mean you killed your CPU?
sorry but i don't think that asus boards (at least P8P67 series...) are better clocker...some weeks ago i tried some 2600k on both P8P67 and UB4-B3 and gigabyte always allowed me to use 1 multiplier more than what asus did...
regarding voltage readout honestly i don't trust what BIOS or softwares say, better to check with a multimeter.
As you could see from my earlier posts, I'm always checking with DMM.
I know we can't compare M4E and UD4 but I'm saying that because of the theory that all board clocks the same on air. That would be correct for subzero maybe but not for air cooling..
yes, that's right, you use DMM.
BTW, who the hell cares about 0.03 volt more or less? i surely don't care, what matter is what frequency the CPU can do, not with what voltage
I care.. because I need 1.61v for stabilize 3D06/Vantage on 5300mhz and on M4E I could run it on 1.585v and 5400mhz. Maybe I can run lower freq because of heat (10°C difference now and then) but it doesn't explane the 0.03v difference on 100MHz lower clock. The max OC is almost the same but the stability is far away from M4Es.
try to use dynamic v-core
the big problem of UD4 is the voltage droop....
play with dynamic to get a "positive" v-droop..... it help much whe past the 4800...
2600k + Ga p67a ud4 b3 F3 official bios stioll no love with Leadtek DV2000 TV tunner is just have a continuos power on off cycle damn those non native pci slots
not OC related but anyone gotten Ubuntu to connect properly? The realtek nic or something just will NOT work for me. Its so frustrating! Dual boot in Win7 works fine 20mbps, go into Ubuntu and i cant do anything, wont even let me log into router...
Does THIS work?

Not like I know anythinhg about linux or whatever...just did a random serach.....
4 days ago i went to a local PC shop and bought a new CPU, not a great chip to be honest but good enough to do something interesting with a stock cooled hardmodded GTX280.
AM3 :: 400538
3Dmark 01 :: 110592
both CPU and VGA are pretty maxed out, in the next weeks i will freeze the VGA aiming for 123k + in 3dmark 01 and a decent AM3 score.
finally got a CPU that doesn't go crazy with the single stage, this one run smoothly at -50° C.
nice work mafio
i just finished my 3d01 as well
thx honda, your run looks good too
1022 FPS in nature with such low clock on the GPU/VRAM is really impressing
i think it was higher like 710 hehehe
ud4 is impressive ..not me ..
i still have to try another 2600k...hopefully it does what seller said it does ..*cross my fingles*
more likely 750 core and 1200+ GDDR
crossing fingers for your new CPU, the next week i've some exams so not much time to bench and test but after exams i'll get another CPU hoping for a better one.
Hi Guys, I have a UD4 R3, 2600K 8GB Vengence C9 - Currently sitting at 47*103 @ 1.4vcore @ 1.16VTT. I want 48*103 but I keep getting #124 and #101 after a few mins of prime while 4700Mhz is rock solid. I see that DVID helps with higher clocks? For those of you running a 2500/2600K what offset are you typically using around the 4.8 mark?

2600K @ 4.8Ghz 24/7 | Gigabyte P67A-UD4
Asus GTX480 | 8GB Vengeance | Vertex 3 120GB
4.7GHz no LLC DVID= +0.09, probobly +0.11 for 4.8
What bios voltages did you set for this??
@nijel, why no LLC?
Also, what does everyone think of the latest F3 bios? I was using the F3d before although I was hopeful that the latest bios would include advanced LLC options.

It's [NORMAL], only way to use DVID and depends on particular CPU and multiplier.
[NORMAL] with DVID 0.00 = [AUTO] = VID
LLC gives me under 1V in idle and Vcore doesn't scale properly for low loads 1 core which leads to BSOD in 0-15% load range. With LLC Standard and higher DVID my idle is ~1.04-1.08 and no any BSOD in the full 0-100% load range. That's for 24/7 clocked system. It doesn't matter if you overclock for benching.
Can't comment on UD4 F3, but on UD7 any LLC level + DVID = system won't post.
