Gigabyte GA-P67A-UD5 Discussion Thread

[stasio]

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.

CR1 or CR2 ?

[ProStreetCamaro]

CR1 or CR2 ?

I can do both doesn't seem to make any difference.

EDIT: Just tried 2133 again and wont go into windows. That is very strange because these settings were linx stable the other day. Dont know what is up with that?!?!

[OC Maximus]

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.

Same here. I can run 100.8x52 or 99.7x53 but no higher. I've tried all kinds of voltages but still seem to smack a wall @ 5.3Ghz. I've tried room temp water and chilled water to no avail. Temps are not the issue. Maybe this can be fixed through a bios update and I hope its not the chip itself. Then again it could be a setting I'm missing to enable or disable. I honestly don't know.

I am stuck at 52x multiplier also but on the UD7. Hope it is bios and not the chip also.

[C-N]

No doubt a BIOS could be made to make theses chips go faster probably with more risk of blowing degrading the chip but in all honesty I think we are at the top of what the chips can do as its clear the boards can go past x52 my own 2500 did x54 without trying & there is a 2600 here @ x56.

Check this dinos22 video out. Same board and cpu. Forward to 6:01 and you will see where I'm stuck. Funny thing is I'm running a similar clock but can't go any higher. Maybe dinos22 can chime in and give us some insight.

You are stuck at 4.5Ghz? If that is the case you need F6a bios and you need to enable internal cpu pll overvoltage. I was solid at 4.5 till I updated the bios and enabled that setting.

Not 4.6Ghz, I'm stuck @ 5.3Ghz.

Just some quick observations with UD5 and 3 different 2600K.

Havent had to much time, so observations might be incorrect.

- Flashing from bios F2 to F6a with @Bios works ok, but will revert to F2 quite fast if you have trouble with oc settings/booting.
- Flashing from F2 to F6A with @Bios, you can then use normal bios flashing from Quick flash on boot. It might still revert to F2, but less frekvent.

My three 2600K are quite different:

L040B690: max 45 mp without "internal PLL", max 50 with it. Runs 4.8 on air with quite good temps. Memory oc not tested.

#1 L040B165: max 48 mp without "internal PLL", max 54 with it. Runs 4.9-5.0 on air with good temps on air. Memory is strange, at or below 4.8 I can use up to 1866 np, above that it struggels.

#2 L040B165: max 50 mp without "internal PLL", max 54 with it (hopefully more with better cooling). Can also do 4.9-5.0 on air, but with higher temps than #1 (+8 - +10c). Memory oc is good, 2133 np.

Gone do some more testing regarding memory oc, hopefully I can figure out why #1 doesnt like increasing QPI/PLL voltage or oc memory above 4.8.


SB really turns out to be a hunt for the golden cpu's with high mp, not much skill required yet.

[sin0822]

i got two D1 steppers same batch and one does 4.8ghz not a mhz higher and the other 5.2ghz these chips have limits not all will do 5.6ghz lol.

I have seen the same things happen. @bios works good provided you have the newer version as the original shipped one causes the op to error. The reverting back to f2 cause of primary bios corruption may have something to due with Gigs new VRM power system which seems to get moody under high draw, that could be dialed less sensitive through a newer bios. I think the f6b is even more prone to that issue.

[ProStreetCamaro]

Is it possible to flash the shipped F2 backup with a newer bios? If so how is it done?

[flesheatinvirus]

I would certainly think so, in fact I heard someone here talking about just that recently. They where stating to flash both new and backup the same. On other boards I just switched the bios on boot like in the Asus Rampage III Extreme to the other then made any changes including flashing. Very nice feature which I do not see right in front of me on this UD5. they certainly claim to have dual bios support but I currently do not know if the second 32m chip is just a fixed safety backup or hot swap/flashable with the other which it should be. Someone here should be able to chime in on that as its an excellent question.

There you go, Thanks dinos22.

same here can boot with 53 multiplier but 54 up no go regardless of volts etc

[flesheatinvirus]

I am seeing the same here only at 56 and change with slight bclk but so far no amount and/or combination of settings is helping matters. 56 is pretty solid though and I should be content but NO.

[OC Maximus]

Hopefully a bios update will help. Can't compete in 2D Benches with only 5.3Ghz.

mate this is SB bull OCing for you. i am stuck at 5205 or so

[OC Nub]

Very true, I would have given my right testicle to hit 5.2 on water this easy with 1366, now I am crying because I cant hit 5.3.

Ain't that the truth.

Tell me about it........

Absolutely. I have a pile of those chips.

[flesheatinvirus]

I was hoping for the new board today but tomorrow is fine too. How about some single channel 3DM and maybe Cinebench R11.5. Give me a few.
