Gigabyte GA-P67A-UD5 Discussion Thread

I am setting up my B3 exchange right now. Doing an advanced rma. Lets see how long this takes!

[ctgilles]

Hey guys,

I still have a B2 in the box because I am waiting for my GTX580. I didn't feel like RMA because I do not use the bugged ports.

Is B3 only changed on the SATA300 or also on other points? Will future BIOS work on B2? I am way too lazy to go to the store so if it works it's all the same to me.

I would advice you to RMA it anyway because later you might not be able to do it and the SATA bug might be a problem when trying to sell it

C-N .. just wondering about your hypers @1067mhz.
do they also freeze 32m on w7 ? what about P95 on W7 ?

if you get 32m errors from lowering vdimm on w7, and not freezing then looks like same issue i have with my corsair

my OCZ don't freeze on vista 64 and XP, but > ~1050mhz on XP my corsair freeze 32m unless i raise vdimm up to similar level that ocz needs.
the corsair is higher bin than ocz, so the corsair min vdimm seems due to 'other' factors (idk )

also my corsair won't run @ default vtt, only @ 1 step lower (was your tip)

i didn't find an elegant solution for XP, just vdimm to avoid freezing 32m


btw, tried f6e bios
apparently my chip now boots 2 extra multi before i need int. pll enabled.
1.5v vdimm setting is fixed (now just normal overvolting)

I am setting up my B3 exchange right now. Doing an advanced rma. Lets see how long this takes!

I just built up my DFI X58 again last night for something to play with when I get round to packing my P67 up for RMA, Just need to contact GB to see if they can do some sort of cross ship thing in the UK/Europe or whether I will be forced to return it to the German dealer I purchased it from & wait for a replacement.

Keep us posted

C-N .. just wondering about your hypers @1067mhz.

Yes best I can get is about test 7~10 before it locks up. I can’t 100% remember what happens in prime but I think they were ok!

if you get 32m errors from lowering vdimm on w7, and not freezing then looks like same issue i have with my corsair

Yes give them just enough vdimm to boot & they will pass memtest (test 4 & 8 most problematic) but fail 32M, little more vdimm lockup.

my OCZ don't freeze on vista 64 and XP, but > ~1050mhz on XP my corsair freeze 32m unless i raise vdimm up to similar level that ocz needs.

Yes I can sort of see that as Chew mentioned the relationship of voltages was pretty critical to getting them running but I spent 2 days going over timings & voltages & improved nothing. He also mentioned you need good Hypers & I'm leaning towards believing him seeing as he's clearly in the know judging by his results.

also my corsair won't run @ default vtt, only @ 1 step lower (was your tip)

Yes I remember, I tested all sorts of things before finding that. My chip/setup is crazy did you see my low volt 5.5GHz post!!! it passes 32M, Linx, Prime etc with crazy low pll & vtt!!! I've not seen anyone else run this low but it works for me.

btw, tried f6e bios
apparently my chip now boots 2 extra multi before i need int. pll enabled.
1.5v vdimm setting is fixed (now just normal overvolting)

Didn’t test this, would be interesting to see if others find the same.

I've flashed back to F5x because I know it works & the newer bios's gained me nothing. Oh & the latest one is dangerous & should not have been released imo due to the Level 2 spike.... it hurt my chip!!!!

We have 24 month warranty in Belgium so I was planning on an RMA when I sell it in a few months. So if they decide not to RMA it, they'll have no legal foot to stand on And the store clerk assured me that the shop would RMA it. I'm too lazy atm to take it back out :p I am away from home each day from 5.45 until 19.00 because of work so fsck the SATA bug

[Falkentyne]

Ok, got my UD5 B3, and it came with F1 BIOS.
Some changes.
1) Board seems to keep its settings when the PSU is unplugged (at least it does for 30 minutes). Old board would say overclocking failed if PSU is unplugged under the same conditions.

2) LLC seems fixed, or seems to match the UD7. Unfortunately, I have no way to test this, as CPU-z 1.56.3 and 1.57 are both reporting the Vcore as the VTT (again). CPUZ needs an update for B3, apparently...

In BIOS: 1.25 LLC1 -> 1.238v
1.25 LLC2 ->1.272v.

Decided to buy a second chip, and it has a lower VID at 5 ghz and boots at x49 without PLL Overvoltage. Way too early to tell whats going on though. I'll have to test both chips with the new LLC1 to see which one I keep.

[TurboDiv]

Thanks for the update. Did you try any new BIOS yet ? Good to hear you dont have the boot issues so far. Please keep us posted on that since its my only problem with Gigabyte.

[Falkentyne]

Only gona say "if it ain't broke, don't fix it."
So I'll only try a new bios if i find a problem.

So far, the same boot instability issues happen if PLL overvoltage is enabled (sometimes, the BIOS can't retain the settings after you exit the BIOS), but that never happens if PLL overvoltage isn't enabled.

LLC1 is definitely mostly fixed. It's not perfect, there IS a droop, but it's not like 0.1v like with "standard"; probably 0.05v (ESTIMATING).

It seems, from TEMP readings, that LLC2 is "about" the same as the old LLC1. That's just going from temps. Only tested LLC2 on the first CPU.

BTW, I have a new chip with a weird code on it.
Batch 3101A209. Decided to buy another 2600k as I had a feeling things would be different on the B3 board.

It has a significantly lower VID at 5 ghz than the first cpu did. (1.355v at 5 ghz, while the other one was 1.390v). Both are 1.235v at 3.4 ghz. It runs HOTTER by several C, however, so far, it's doing 5 ghz at lower voltage (FOR THE MOMENT).

I'm not going to waste my time priming on this cpu, especially without voltage readout, but I'll tell you this:
With LLC1, the first chip locks up the INSTANT (yes, INSTANT) I hit "start" on small FFT prime95 (the L045A998), at 1.445v and LLC1. This CPU was able to prime to iteration 2 before I stopped it (about 1 minute; I don't like the temps), at that same voltage. I can't monitor the voltages, so I don't know what vcore it's getting under load.
I will say that when I put the BIOS voltage at 1.50v on the L045 cpu, and LLC1, it primed for about 20 seconds then rebooted. (If only I knew what the voltage was!). So the weird 3101A209 cpu is doing better for now--unless it degrades.

BTW This one is Costa Rica..that may explain the batch#.

BTW, it's VERY pleasing that it kept the BIOS settings while switching cpu's. (often, just removing a CPU from a motherboard causes the BIOS to reset). Can't test leaving the computer off overnight, since I never turn off my systems unless I'm eating its guts out (Thank you, Claymore...you damn anime...)

[nijel]

Only HWiNFO32 reads everything correctly on my UD7-B3. You might wanna try it.

[stasio]

Aida64?

[nijel]

Nope. Vcore 2.888-3.000V constantly. No Vddr at all. No HDD temps also. Reads board "unknown".

Strange I've never found this.

Sounds better, Easy tune should show you the voltages & I know you dont want to beat up on your new chip but I'd appreciate a few figures if you dont mind doing a few tests.

Std voltage in bios =, ET Idle=, ET LinX Load=

Level 1 voltage in bios =, ET Idle=, ET LinX Load=

Level 2 voltage in bios =, ET Idle=, ET LinX Load=

You only need do 1 loop of LinX to give us an idea & it can even be at stock speed.

Batch 3101A209.

Found this years ago on TPU.... Thanks to W1zzard

Looks like you got a Costa Rica, 2011 week 1 chip

Reading the Intel FPO/Batch Code

Example: L149A463-0726

1st letter or digit = plant code (Malay)
0 = San Jose, Costa Rica
1 = Cavite, Philippines
3 = .............., Costa Rica
6 = Chandler, Arizona
7 = .........., Philippines
8 = Leixlip, Ireland
9 = Penang, Malaysia
L = ............, Malaysia
Q = ..........., Malaysia
R = Manila, Philippines
Y = Leixlip, Ireland

2nd digit = Year of production (2001)

3rd & 4th digits = week (49th week )

5th - 8th digits= lot number

10th - 13th digits = serialization code

Decided to buy another 2600k as I had a feeling things would be different on the B3 board.It has a significantly lower VID at 5 ghz than the first cpu did. (1.355v at 5 ghz, while the other one was 1.390v). Both are 1.235v at 3.4 ghz. It runs HOTTER by several C, however, so far, it's doing 5 ghz at lower voltage (FOR THE MOMENT).

a fresh start

[Falkentyne]

Ok, 1.25v BIOS, LLC standard:
(100x40, 4 ghz, 4C, 4T)
LinX (AgentGod's IntelBurnTest with latest binaries).
Windows XP
Using HWinfo32 for voltages.

1.25v BIOS: LLC standard:
Idle: 1.224v
Load: 1.164v

1.25v BIOS: LLC Level 1:
idle: 1.248v
Load: 1.224v

1.25v BIOS: LLC level 2:
idle: 1.260v
Load: 1.272v

(ran prime95 really fast to doublecheck LLC2 to make sure).

[C-N]

Awesome thanks man, looks great ill have to get on and rma mine

[Falkentyne]

C_N,
I just did a 15 minute prime blend run at 5 ghz to check the vdroop, because I felt the above example wasn't realistic for what you run your own chips at (since HWinfo was able to monitor the voltages).

BIOS voltage was set to 1.445v. LLC1
here's what I got.



So just as I thought, the board droops the idle voltage more at higher voltages (but as far as I know, ALL boards do this). At 1.25v LLC1, the idle voltage was 1.248v, a 0.002v difference from BIOS (basically, none), and load 1.224v, a delta of 0.024v between idle and load.

At 1.445v, idle voltage was 1.428v, load 1.404v. 0.17v difference between BIOS and idle. The idle to load voltage delta remained at 0.024v.

Didn't test it, but I can assume LLC2 will have the same idle to load delta (hopefully), but the voltage rising at idle (to around 1.462v idle, 1.484v load).

That's if everything goes by the books...
Is this still acceptable or is this a disappointing result?


BTW I stopped prime blend on the next batch loop (256k), after 512k passed (yes I know it was only 15 minutes) because the temps went slowly up to 82C, and that was too much for me.

BTW 4.5 ghz was going blend at 1.236v load (1.265v BIOS), stopped it at 15 minutes (ran two 15 minute tests)...guess that isn't bad, is it?

(My first run passed the first loop at 1.224v load, so I decided to get y and set the BIOS to 1.235v and try to run blend at 1.211v load. Fat chance. Rebooted fast. Tried 1.25v bios (1.224v load) and it rebooted a minute or so into the test. Yay for instant degrade? Set it to 1.265v, ran 15 minutes fine, so I went to 5 ghz and 1.445v bios, ran 15 minutes at 1.404v load, then temps got too hot on 2nd group, went BACK to 4.5 ghz and 1.265v bios, ran 15 minutes (again) at 1.236v and decided to stop wearing down the chip.

I know it's going to degrade more (like yours have done), but if this chip winds up being reasonably stable at 4.5 ghz 1.245v load, and 5 ghz 1.414v load, that's a pretty decent chip, right? (but not "low voltage" like some...)

(Boots X49 without PLL, X50 causes instant OC failed error).

I think it depends on what boards you have used in the past as to whether it’s acceptable or not. IMO GB have always had pretty rough voltage control compared to others I've used however this has I think without exception never taken anything away from their ability to perform. I would be quite happy with Level 1 as it’s very much better than Intel spec/droop & In keeping with other boards I have used. Level 2 I don’t think should overshoot, I would be much happier if it didn’t overshoot on load but then again that’s just my opinion.

(Boots X49 without PLL, X50 causes instant OC failed error).

All chips burn in (avoiding the degrade word) I think it’s just far more noticeable when you can max out a chip in 30minutes compared to days gone by when it took many hours if not days of tweaking to max out a chip/board. It’s also worth mentioning we used to be board limited like x38/48 fsb for example now it’s the chip that’s holding the board back so you are going to see the chip losing its new shine much faster.

All 4 of the chips I have used have ended up needing something like .07 ~ .09v more voltage after 2/4 weeks running where they appear to settle.

I think based on my own chips 5G 1.4v is very good & 1.45 being more like the good end of average. The problem I see is the information available to base an opinion on is a little flawed having a jumble of results with new chips that have not burnt/settled in & not fully 24/7 stable rigs mixed in with perhaps a few sledgehammer overclocks if you know what I mean so its very difficult to class what’s good & what’s not.

Finally got a hold of a decent chip.

CPU #3: i7 2600k Batch# L045A912 #2417

http://valid.canardpc.com/show_oc.php?id=1709100

Time for some Global Domination, and maybe a new set of sticks

[flesheatinvirus]

Very nice chip OC maximus, looks like another fine keeper. Nice Pi score.

[C-N]

Yes looking good OCM, You already got some of the best sticks going dont you like them?

[OC Maximus]

Thanks guys. tRCD won't drop to 9 no matter what. I may just get another set of the same or a similar set and try again.

[Hondacity]

oh i like that idea

[OC Maximus]

and to you HC

[Hondacity]

so gay lol

[flesheatinvirus]

I smell Blowfish.
