Gigabyte GA-P67A-UD5 Discussion Thread

[ProStreetCamaro]

WARNING!

Stay far far away from the new F6b beta bios! If you run AHCI or RAID you will not get past the gigabyte screen where you would hit DEL to enter bios. It will hang there and sit there forever. I had to clear cmos a couple times and finally came up with a checksum error and it automatically reverted me back to the backup bios F2.

[flesheatinvirus]

I did not even know there was a f6b out yet but have seen that situation occur once with the f6a a while back.

[famich]

ok so just stability testing with megahalems before going to the chillers.
could do 48 multi at 1.4v cpuv, needed 1.415 for 50 multi
below is 50 multi testing at 1.415 cpuv bios F6a.
just getting started - all is well so far!

Great CPU-what bacth..? 040xxx?

[SteveRo]

not really that great - llc 1 enabled makes in look lower cpuv.
Also i can't seem to boot at 53x
I will post my settings if I can't figure it out.

batch = L040B705

[Johnny87au]

Stevero u using the right cpu z package? Because 1.1 seems very low and might not be your vcore more like your vtt..

I havent figured out 5300 yet. 5200 is easy, then hit a wall trying 5300.

[famich]

I thought that 2500K d be better overclockers due to the missing L3 cache , but it seems that I was wrong .

2600K s 040Bxxx are excellent , need lower VID to reach 5Ghz than
most of 2500.. it looks they ve put better silicone in more expensive CPUs

Pity we don t have here 2600K s yet

[C-N]

Where u from?

They are in high demand & short supply but they are about in the UK

[famich]

I am from the Czech Republic , EU

WOuld like to get 2600K 040Bxxx looks to be a hell of a good batch
maybe after some time someone ll sell one of his "surplus " ..

Up and running finally........

Here are my first few benches:










I too have hit a wall. Cannot boot in @ x53

[flesheatinvirus]

Nice numbers, love the Aquamark. What batch and bios on the ud5? I think I will run some 01/03 later tonight perhaps.

Thanks. Still have some tweaks and mem timings to work out.

UD5 Bios F6a

Would like to figure out this x53 issue.

OCM

[flesheatinvirus]

First try disabling Ht then various cores to see if if helps at all. I needed about 1.55v core at first and bump QPI/Vtt to 1080 auto on the rest.

[OC Maximus]

Was able to boot in @ x53 by lowering bclk from 100 to 99.7

5.3 GHZ wall seems to still be there.

Anyone else having the same issue or do I just need to tweak more of my voltages?

OCM

[flesheatinvirus]

Once I changed to the f6a bios 53 was not really a problem though my board runs only single channel from day one and is being replaced. I got my rma from gig which is cool and have another ud5 coming from another source even faster. I will keep testing on this board until new one arrives. I started at 1.575v cpu and worked backwards down to settle on 1.475v stable. Ram is Gskill 17066 Pi which runs either Auto XMP profile one at 2134mhz or disabled with any speed combi up to 2155 at 101 bclk. Reducing bclk below 100 is sometimes needed depending on chip quality. My 2600K needs 1.5-1.55v for 53-55 range, 56 needs 1.575v.

[C-N]

Yay..... home sweet home.

@ flesheatinvirus

Nice x56 action, you got a kick ass chip there

Up and running finally........

Looking good, interesting to see how the Super Talents do on the board they are some nice sticks.

[flesheatinvirus]

Should have my new board today or tomorrow at the latest. Then its retest time again.

Sorry to hear it was your board, that chip is awesome got to be right up there as one of the best around. I seen Pt1t run a sub 6min 32m @ 5.6GHz just incase you run out of benches to play with...

@ OC Maximus

Cool bench table & POST diagnostic card all hooked up to water as well, It puts my home made table to shame.

Is anyone using Load Line/Level 2????

I have just been reading the UD7 thread & they appear to be able to use it. My board will not post with Level 2.

[SteveRo]

I cannot use LL 2 for anything with p67UD5.

Also, I am also stuck at booting at the 52x multi

I think I have tried just about everything -

I have tried cpuv up to 1.62v.
Cpupll as high as 1.88, as low as 1.68v
mem set low or high makes no diff
qpiv from 1.16 to 1.20v
Tried both megahalems and chilled water.

I think that we are "Test pilots for Sandy Brigde".

I have this combination and it doesnt work good at all sadly. Only when nothing is overclocked does it seem to run normally. I overclocked it at 4.7ghz seemingly without a problem, then a few restarts later and it refused to even boot at that setting. Since then no matter what I've done I cant get it to work at that setting again, neither can I overclock it without using Turbo mode cause then it refuses to boot. I tried clearing CMOS, flashing different Bios and tried just about every single setting. Often it copies the backup bios back aswell when it fails to boot, but sometimes it just gets absolutely stuck and the only way to get it to boot again is to clear CMOS.

I cant recommend this card nor any other P67 gigabyte cards from what I read until they sort out their Bios. I feel like a test pilot for an alfa version. This is just unacceptable. I have often had new chipset releases and never before I have seen such unstable motherboards at release. Gigabyte doesnt seem to be only brand that has problem with Sandy Bridge, but I really wanna see em sort out the Bios asap else I'll return this and get another brand.

Btw,
my G.Skill Hypers (2200 8-8-8-24) cann't work at DDR3 2133 at all,with x46 and above only manage 1867 CR2
BIOS?
So many restarting,etc.....BSOD,off the PSU,clear the CMOS....
Any forum you read,same things...
Any clue DrWho? and all Guru's from Gigabyte....

stasio are you having issues yourself? For the most part I am not having any issues myself. I do think the bios are still flaky but that is to be expected for a whole new platform.

Yes, above DDR3 1866 start to freeze,I cann't set CR1 at all.
With P55 no problem.

Dinos22 got hypers kicking butt over here

http://www.xtremesystems.org/forums/...d.php?t=265130

I personally found with my rig & hardware 2133 was not worth running over 1866 as there was little improvement I could run safe 24/7. I found disabling channel & rank interleaving made my UD5 run stable @ 2133 where as enabled with my kit required lots more voltage. Might be worth asking Dinos his view & wont cost anything to disable interleaving.

[SteveRo]

man either this CPU cooler is crazy nice or you boys have some seriously low ambients

that is very cool

The megahalems are very nice coolers, I have the super version (has some copper fins).
Probably the best air cooler I have ever had.
The cooler comes with special (black) springs to cinch down to 70#s tight.

That is very strange. I can run my Ripjaws X 1600 7-8-7-24 8GB kit at 2133 9-11-9-30 just fine.
