Gigabyte GA-P67A-UD5 Discussion Thread

[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...)
