******Gigabyte GA-P67A-UD4 Discussion Thread******

[Demo]

You should add increasing cpu pll voltage can also help with 124's.

My experience with upping the PLL to 1.88v WITH c3/c6 is that it only prolongs the time b4 it 124's. Altho the C3/C6 is a different problem of its own.

[Falkentyne]

True, but you can use this with vcore to achieve a balance.

I found the best use for it by upping PLL to prevent 0x124's when you are at light load (when not using offsets) when using high LLC that raises the vcore slightly from idle to light load to heavy load (when using fixed vcore). So, random 0x124 at light load when ur fully stable at heavy load when vcore is 12mv (0.012v) higher than light load? Upp the PLL and profit!

Some people have been able to lower vcore by lowering the PLL but I haven't been able to benefit from that on either CPU.

Hi guys

Since this is a GA-P67A-UD4 Discussion Thread, although you speak about overclocking, i find it appropriate to ask it here
I have a rather weird problem with my ud4.The mobo works just fine but when i use a display port cable to connect the screen with the vga is when the problem pops out.
When i power on the pc after a few secs the gigabyte logo appears and then the computer shuts down and then all by itself turns on again and the same thing happens all over again entering on a loop of continuous turn ons-turn offs.
It is only when i plug out the display port cable that my computer boots normal.Eventually when i hear the windows sound i plug again the dp and all works just fine.
When i use a dvi cable that is not happening.

I have noticed that when the computer is shut down the mobo lights (up and right) are on and when i plug out the dp cable the lights turn off. Its like the cable supplys electricity to the mobo.
The whole thing is a bit annoying because i have to do that all the time and i want to use the dp cable.
Is it possible this is a bios thing??
I have the latest official F4

Progress (or not) report on 2600K on Z68x-UD4 overclocking.

Well, it seems that maybe 4600 is my limit, 4700 & 4800 don't even want to POST.

Running 1.36 (1.35) vcore (which is setup by default according to frequency.
LLC Level 6 - 8
no turbo
almost everything else in auto

Disabled most energy settings for CPU.

Not sure what I should risk to get a little higher (I'd like a good stable 4800)

What are the safe maximum volts for vCore, QPI, System Agent, etc ??

[Hondacity]

did you enable pll overvoltage?

[burt123]

did you enable pll overvoltage?

Pretty sure it is

[Demo]

Pretty sure it is

Double check if its enabled instead of just AUTO.

[burt123]

Double check if its enabled instead of just AUTO.

I had a checksum error, which auto loaded the 2nd bios, so I had to re flash f7d again, so yes it is enabled.

If I change the frequency above 46x, it just won't post, it tries, and tries, and tries, but just cant do it, I have to basically cold boot it, then it reverts back to 34x.

Seems like you can't set the vcore to some high level, so it will post, then change it from there.

Currently running 46x, no turbo, LLC Level 7, 1.36 vcore, etc.

[Demo]

Well 4.5Ghz is good for 24/7 anyway not much of a loss TBH.

[Frost_Bite]

I really like this board, but it's giving me fits with my GSkill CL6 DDR 1600 kit. Anything over 1600 requires me to manually set every memory timings, basic and advanced. I've figured out really good settings for 1866 @ 1.5v, but can't seem to figure out the correct advanced timings for 2133. 5.0GHz @ 1.38v loaded with RAM @ 1866 7-9-7-24 1T 1.5v is screaming, but I'd love to get 2133 running so I could run tests to see the difference the extra RAM speed is giving me.

Demo

I know you are running the same GSkill kit as me, could you please screenshot or list all of your options under the memory tab for 2133? I'm 85% there and could really use someone's settings as a guide. The suggestions I've gotten so far were all from a P8P67 board and it didn't require settings all the timings I need.

Thanks for any help

Seems like a BIOS bug to me. The fact that you can't go above X47 shows that PLL overvoltage is NOT working. (it doesn't work on D1 stepping chips at all).

You are using a D2 stepping, right? And that board is a B2 as there is no f7d for a B3 board.
You may want to consider RMA'ing that board and get a B3, because that wall you hit is clearly a firm BIOS bug.

I loaded up the XMP profile and just manually adjusted the timings to 9-10-9 since its the only timings that runs at 1.500v or 1.5400 for some as I've heard.

[Frost_Bite]

Gotcha, I thought you had yours running at 7-10-8-27 instead of 9-10-9-27. I'll try that tonight, but if I can't do CL7 2133 I'll probably stick to 1866.

Thanks

[Andrea deluxe]

any new bios?

[Frost_Bite]

F5b is out, but it doesn't offer any improvement. I went back to F4 final and it's been working great since starting to figure out this board.

I am using a D2 stepping chip, and it's GA-Z68X-UD4-B3, and I flashed it with the F7D bios that stasio post's...am I using the wrong bios ???

http://www.gigabyte.com/products/pro...px?pid=3849#ov

Original bios was F5, which isn't even on the Gigabyte site, all they have is F6, and is only 1.54mb, the Stasio F7D is is 4mb, but the F7A is only 1.4mb.

I think I will try the F7A, and see what happens.

Your opinion ???

[Falkentyne]

Oh...you're using a Z series board, not a P board....that explains that.

Well anyway, what is the MAXIMUM multiplier you can do with PLL overvoltage DISABLED? x46, right?

You can't do x47, regardless of enabling or disabling it?
If that's correct, then the BIOS isn't working correctly.

BTW There's no such thing as a CPU that needs PLL overvoltage enabled for x42 (as that's the only way you would have a wall at x41 with it disabled).

[Mafio]

playing with a pair of Kingston HyperX 2000 cas9 Elpida BDBG.

7-11-7-27 1t @ 2220 MHz



the ram aren't exactly in their best day, 2 sticks out of 3 back to life after 12 hours in the freezer but now get really unstable past 2 volt...
the third one is still dead.

Update.

Have re flashed with genuine F6 bios, and can now boot @ 4700 & 4800, but not sure how far to push the vcore & vtt voltages.
Currently vcore is 1.37 & vtt is 1.11 & sa is .95, using level 8 llc.
Under load vcore goes up to 1.418 @ approx 70°C.

[Falkentyne]

So those beta bioses are bugged, then ? (PLL Overvoltage doesn't work?)

[Demo]

How do we get turbo mo to get past 3.5Ghz on this board. I have it enabled and the following at x38/x37/x36/x35 and when I run a single 1M/32M Pi it still goes upto 3.5Ghz only.

Hello.

You can add memory compatibility F3-12800CL8T-3GBPI-B into the motherboard Gigabyte UD4 P67A B3 I care about the 100% memory usage, now I'm forced to work and clocked at 1333MHz CL9, CL8 standard 1600MHz and 1.6V voltage

lynx 0.6.4 in testing or prime95 error jumped after a few minutes, three-channel apparently does not want to pledge to work closely, I checked the dual channel but to no avail, I think that the amendments will BIOS compatibility for me

Just out of curiosity, why are you running all three sticks of triple channel X58 on a P67 system?

[kuziu]

residue from the old platform, the P67 are problems.
vtt voltage and does not help vDIMM

Enable the C states and you are good to go...
