New motherboard Gigabyte

[KING_OF_SAND]

So I purchased a new Z77X-UD5H board to replace my ASUS x68 but I am having so issues that make absolutely ZERO sense, and I think that is because I am switching from an ASUS to a new brand. The really only issue is with the voltages.

For example: My i52500k can do 4.6ghz no problem at 1.35v as tested on my ASUS board. So I bumped the multi to 46 (base 100) and the volts to 1.35. Boots okay and everything is fine until I look at CPU-z and realize the volts are not reading correctly and it IS the latest CPU-z. When I run prime95 it will do about 5 tests then crash. I found out this was happening because my CPU ONLY goes to 1.35 at idle and at load drops to 1.322 which is NOT enough. In order for my to hit 1.35 at load I have to bump the volts to 1.38v ~ 1.4v and load is at 1.35 ~ 1.36 which can run Prime for several hours.

Here is the kicker, when I adjust the volts to 1.4v my idle is 1.4v no matter how low the core clock goes (1.6ghz). What the Hell?! This is backwards!

I am using the F14 BIOS.

BUMP! (I hate bumping but this is important as I only have a few days to return if it is defective) which does not seem to be the case.

This is also a quick update. I got the volts to stay at 1.356v under the LLC set to "Extreme" in the BIOS. Unfortunately doing so prevents the CPU from every going lower than 1.356v. And the core clock still idles at 4.6ghz. Not to big of a deal but it is frustrating knowing something is not working the way it should. I've noticed while fiddling with the BIOS when something says "AUTO" that generally means it is not on (which should be on and is so on most other boards). So I have had to mess around with a few odd things.

I am still messing with it but dam did Gigabyte screw this BIOS up. I have also contacted Gigabyte about the issue but chances are they wont get back to me within the 13 days I have left. If this is a hardware issue, I will probably get rid of Gigabyte and never go back. This would be the 3rd Gig board I have had that has been a nightmare.

Just because you dont know enough mate.

Update the bios.

Turn load line calibration to extreme

Realise you have a lot to learn

I always have a lot to learn, but the BIOS is fully updated and I did set the load line to extreme. I am just unfamiliar with the board. I can do 5ghz+ no prob on an ASUS board, but this is just crazy and looking around the internet I am not the only one who has frustrations with Gigabytes BIOS. I have NEVER seen a board in which voltages DROP the more load you put on the CPU. Every board I have uses (mainly ASUS) adds more or none at all.

If they were both set at the same setting then it's just that the LLC isn't as powerful on the Gigabyte board.

It looks like you've set a fixed voltage which is why your volts aren't dropping with speedstep (x16). You need to setup an offset voltage or you might as well turn off EIST.

That's exactly what you should see - that's vdroop and is designed to happen - it is what LLC is meant to compensate against. Vdroop isn't a bad thing but rather a safety design feature. There's some info on the bottom link in my sig if you have time to read.

I understand the offset voltages I just cant find it in my motherboard. What other name do you suspect it be under?

As for the vdroop, like I said I have never seen it done (probably because I have always disabled it.) I have been using ASUS boards sense 2008 and never used another one for my main rig. So some of this I will need to refresh on.

EDIT: It is under DVID for dynamic voltage adjustment. now I just need to configure it to be 1.35v max.

Now need to get the core to drop at idle.

I think you need to read up in Vdroop//LLC, it's not a Gigabyte thing.

We all have a lot to learn, till the day we die.

Going from a board you were used to to a board that works slightly different doesn't make it necessarily bad, just different. Read about Load Line Calibration, a bios update would be very useful, and calm down, it's not the end of the world , you're good.

Now need to get the core to drop at idle.

Have a double check of how you've set your multiplier - in order for the cpu to drop down you'll need:

1. EIST on (Enhanced Intel Speedstep Technology).
2. The CPU ratio to be set on auto (this allows the motherboard to decide when to utilise speedstep).
3. The Turbo ratio to be set to x46.

Hopefully that helps some.

I am starting to think the BIOS is broken. I have done EVERYTHING and nothing will drop the volts or core clock. EIST does nothing, C3 C6 does nothing, C1E Halt does nothing, enabling all does nothing. literally nothing.

I did everything you said Puppet and none of it worked. What happened is now I am at 1.38v and the CPU wont go passed its stock 3.3ghz

Just for giggles I even reverted back to factory BIOS settings, and it seems the same thing happens. It stays at 3.7ghz and 1.2v 100%. What was gigabyte thinking?

why don't you use the newest bios F15q? as the one you use is nearly half a year old

Just a shot in the dark here, but did you check Windows power options in control panel under processor power management...minimum proceesor state... not set to 100? I am not posistive if this will over ride intel speed step function or not..
