I5 2500k - Gigabyte Z68XP-UD3P Overclocking

hey all
Ive got this Gigabyte set up, with 8gb vengence ram, Corsair water cooling. I was going to update to the new UEFI bios, however im reading that isnt the best idea?. Am I best sticking with the current bios?. Ive only tried overclocking using the Gigabyte turbo app! but anything higher than the first boost (yellow button) just results in system rebooting cycle, until i go into Bios and reset to standard defaults. Not sure why it cant handle it as there appears to be not overheating issue and I have pretty new and solid Corsair 650w PSU. Is the manual overclocking options as per page one of this thread more likely to yield stable results for me?

Tbh the amount of time you will spend in the BIOS once the system is stable you may as well stick with the more stable normal BIOS imo. As for the Overclocking problems I wouldn't recommend using the built in app.

The BIOS settings that Neil recommended in the original post here are pretty damm solid. Helped me a load with my first self-build and overclock and my system is still running strong with the settings he recommended. If you have any problems just post back here and I'm sure people will be happy to help you, including my self :)
 
The UEFI bios for this board is rubbish. Unless you are planning on running stock just use the F7 bios. The UEFI removes quite a lot of features that are handy for overclocking and is also a pain to flash back although it can be done.
 
Cheers guys! I ll stick to current bios and try the manual overclock from page 1. So the GB app is a bit useless?! i was surprised my system thru a wobbler on the slightest overclock using that app! its a pretty solid build and the Watercooler while not the top range version keeps the CPU super cool so far. having said that Ive got to say im not bowled over by my first Intel build! Ive been building AMD only systems since the late 90`s and find this build lacks a little va va voom! . Hopefully a successful overclock will sort things out :)

Yeah that's the thing with Intel. They overclock very nicely (Currently on 4.4Ghz with air cooling and no problems what so ever.

For some reason it doesn't like 4.50 very much, apparently due to bad power management with this board and perhaps a unlucky pick of chip. But for the price of this mobo I'm not complaining.

Just make sure you monitor the voltages with something like HWmonitor and the temps etc etc, Give it a few runs on burn test and then at a later time a all night prime95 if you have the patience.

Do you have it on a fixed vcore or dynamic? I have tried overclocking with this board but found dyanmic offset wasn't stable and with fixed vcore i wasn't sure if 1.32v even when on idle was a good thing or not...

Yep that's the thing with this board. The dynamic VCore is very unstable. Best thing to do is set a manual VCore and use LLC. If you read back in this thread their was a discussion about it at some point which help me out when I first overclocked mine.
 
p.s. I have never really overclocked anything before. Ive always built the best AMD system I could at the time and never felt the need to!. so im a little lost with the whole LLC and vcore!!. I assume its all explained in this thread?.

Yeah well use the settings in the first post of the thread as a template. The LLC should be fine at the level recommended. Mine is still set as such.

As for the VCore boot the system with the template VCore and run 10 run of Intel burn test on the highest setting. If no problems occur take the VCore down a notch and repeat until the system crashes either on start-up or when running the burn test. Once you find the point it crashes at bump the VCore back up to the point where it was stable and leave it there for now.

Then later today or tomorrow leave the computer on over night running prime95. Prime95 slowly adjusts to get more and more demanding on the CPU so it should test most possible situations you're CPU will encounter stress wise. If you wake up to a bluescreen persist to bump the VCore up one more.

If other problems persist post back here and I'm sure we can try and help with other settings such as VTT and DRAM voltage. But like said Neil's settings are pretty solid in the first place so it shouldn't come to this ;)

Make sure you monitor the Temperature and VCore while running the tests. I recommend HWmonitor. You don't really want the temp over 70/75c and a VCore no higher than 1.42/1.45v. VCore wise I'm running at 4.40Ghz and get a VCore of 1.31 idle and around 1.36/7 under load so aim around this. Obviously the higher the overclock the higher VCore you will expect so if you are going for a 4.50 or above expect higher ;)

As for running it over night this kind of requires abit of trust but after doing the testing with the burn test before hand it should be ok. The system should shut-down before anything bad happens. If you are paranoid like my self (And a poor student how wouldn't be able to afford another computer). Set your self aside an afternoon and having it running. Boil the kettle and catch up on a TV show or watch a movie. Keep checking back intermittently to make sure you're computer isn't on fire XD

thanks Syther, Will give it a go at the weekend. fingers crossed!. I noticed that the memory reads as 1333mhz in the bios! shouldnt it read 1600Mhz ( Corsair CML8GX3M2A1600C9 LP Vengeance Memory 8GB 1600MHz CL9 DDR3 )

It goes to that by default. This is something you can do at any point. It won't make it unstable/require other settings to be changed.

In Advanced Memory change you're Extreme Memory Profile X.M.P to profile 1
 
/\ Thanks for the advice Syther101!

BTW I had similar vcore when i was doing 4.4/4.5 GHz, just the high vcore on idle was niggling at me. But I guess it has no negative effects if everyone in this thread is doing the same with this board.

Yeah I think the reason the VCore will be higher at idle with this board is down to not being able to use dynamic VCore function due to making the system unstable. But tbh you can't complain with the price XD. and Imo for the price this board is great
 
I'm running 1.35v with 4.8ghz and my voltage clocks down at idle. Not had any problems with instability tbh other than the odd crash here and there.

How did you do this because the major blocker on this board is that dynamic offset is grayed out as soon as you try and set a vcore of your choosing?

Can you post your settings?

My bad, voltage does stay the same. Just had a look i'm sure it used to drop down at idle along with the core speed ? At the moment it's sitting at 1.368v idle and 1.404v under prime (1.35 set in bios).
