Gigabyte GA-P67A-UD5 Discussion Thread

[nijel]

Now switch your screen name you freak!

[TurboDiv]

Quick boot is disabled form the BIOS but i still don't see the first screen with the BIOS version and CPU speed, Gigabyte logo is also disabled. To be honest i don't care as long as it boots up fine. This morning it also booted up fine with no problems.

Now switch your screen name you freak!

If it was only that easy.

[Falkentyne]

Glad some people are feeling happy with their board now.

[TurboDiv]

Unfortunately board didn't boot today. Gave the old "Overclcok failed screen" again after 2 success boots. Thats ok, i guess my memories are not compatible or my CPU IMC is bad...

ps: I've just updated the mobo to the F3g bios, only the main bios this time, with the same steps as before to see what happens. Also put the memory to the 18.66 multiplier with its default settings. And this time i clocked the CPU through the Turbo Multipliers and set the TDP and Power limits to 200 each.

new GA-P67A-UD5-B3 - F3g bios anyone tried it yet? anything changed

Fix: remove Floppy Support
Fix: BCLK 100

Hey Stasio,
Does f3g still have the changes that f3c had as respect to cold booting fixes etc? Should I just stick with f3c as my b2 board was plagued with cold boot issues?

Is there anyone who can take a DMM to a B3 board and measure the real vcore voltage (compared to HWinfo32) coming from the choke or caps, with LLC1/2/standard, like they're doing in the UD7 and UD4 threads? I don't have one...

[sin0822]

DMM is very cheap man, like 10 bucks, you should buy one, they are very useful.

[Falkentyne]

I tried to buy one about 6 years ago and a good one with I think it was called trueRMS or something cost $30+ Then I went and looked at those $500 ones with oscilloscopes and wanted one of those

[sin0822]

lol you gotta know how to use an O-Scope before buying one. They are a huge investment. The difference is that a DMM will give you a fixed reading, while a O-Scope will give you a reading over time, usually much more precise.

A DMM is a great way to start, even a cheap one can do pretty much as good as a $30 one, the truth is the more expensive the more features, and you really only need DC voltage reading, continuity, and resistance(ohm) measurements to do all of the mods/measurements. All the cheap ones have these abilities. its a great tool to have, i have 3. I have been thinking of adding an O-Scope to my arsenal, for reviews really. but $200 bucks is a lot to spend on reviews, especially when its my hobby. but in the future it looks like its going to happen.

I think the issue you are having is memory related also. I have the same G.Skill kit in your sig and I also get the oc failed screen on cold boot, and random bsod's. If I switch out the memory to another kit, with the same timings and voltages it is stable with no issues.

Don’t know how relevant this may be but I'll say it anyway....

On some bios's (from B2 experience) I find the "IO Latency" jumps about between 1 & 2 if using dimm slot 2 & 4, sometimes this is a little random & other times going beyond 100BCLK makes it lock into 1 rather than imo the more stable 2.

I would suggest if you aren’t already to try slot 1 & 3 & leave Performance enhance at std to try to rule out your memory.

[TurboDiv]

@OC Nub, believe it or not but your post up there made me happy ! I would be happy if its just a simple mem issue. The next step for me was to send my kit to someone from here to test on their stable motherboard but since OC Nub tested it already i think its pretty much proven to be a mem issue. Now the Q is which memories to get ? I prefer something 1866 or above.


@C-N im using slots 2 and 4 since it was discussed they were the preffered slots.


PS: Loing time ago (January 9th) when i ordered my parts on release day G.SKILL did not have any P67 certified memories and the only option i had was with these memories. One of their guys in their forums suggested i do an RMA but the exchange policy was only 30 days. Here i am 3 months later with a B3 revision board and my memories are not compatible. I wonder if i explain my pain to G.SKILl would they exchange or im just ed ?

[Falkentyne]

I think it's time for C_N to get his B3 board. He's going to love the new BIOS if he does...

[stasio]

For UD5-B2 new BIOS F7 is also out.
Btw,he can crossflash with modded B3 BIOS.

[C-N]

Already tested them & went back to F5x...... Didnt like needing more vdimm with the b3 bios

[Falkentyne]

You need more vdimm?

[Splave]

im glad C_N is in this thread

Hi C-N,

My PC specs are as follows:

GA P67A-UD4-B3
2600K @ 4.5GHz, @ 1.35V (=1.332V Load), LLC Enabled, energy saving features turned off, Turbo OFF, R-TRCinOS OFF, HT ON.
8GB HyperX Grey @ 1600MHz 1.5V (=1.548V)
2xSapphire 6950 2GB CF
Corsair HX750

I read in one of your posts that for CrossFire PCH core should be at about 1.14V to prevent the graphics driver crashing.

Well, I have had graphics driver crashes (...video driver has stopped responding... then BSoD: 0x116 Video TDR Error) but never under load. I can run 3DMark11, Haven, games etc. Unfortunately, the new Catalyst drivers do cause BSoDs rather often for several people and now I'm not sure if that 3 crashes I have had were brought about by the driver or the low PCH core.

What do you think? Shall I raise the PCH core? I'm a bit worried since I don't know what else would that affect. In fact, I've never read about increasing the PCH core before.

[nijel]

GFX pcie lanes are direct to CPU. Why you need to raise PCH?

Just give it a try. It won't blow up your board. Try up to 1.2v maximum for testing.

yea, right?

Thanks. Will give it a try.

Don't you guys think that 1.35V is a bit too much for 4.5Ghz? I cannot make my 2600K stable at 4.5Ghz below 1.35V. This might be ok I don't know but I know lots of ppl who have achieved a stable OC @ 4.5Ghz @ around 1.3V.

Thank you.
