Hey OCUK,

New guy here - I posted a few months ago asking or some help to restore my somehow lost BIOS profile - more on that later...

I picked up some more RAM and a few fans for my rig last week. I fitted everything last night and got so excited by it all that I feel I want to pursue this a little further and actually learn a few things.

I bought an OC bundle back in 2011 - "Titan Exodus" Intel Core i5 760 2.80GHz @ 4.00GHz Quad Core DDR3 System

Up until this year its plowed through every game I've thrown at it with ease. But as of late I'm starting to notice she's struggling a little. This weekend I played the Overwatch Beta and noticed quite a few frame rate drops and some occasional screen tearing. This was running the game on 'High', one down from 'Ultra'. The same is happening occasionally in BF4.

Stop rambling and get to the point I hear you say...

Something fishy is going on with my MOBO and BIOS profiles. I feel like I need to get to the bottom of it before I invest in any new parts to upgrade this thing, a new GPU etc.

The MOBO is a Gigabyte P55-USB3, spec here: http://www.gigabyte.com/products/product-page.aspx?pid=3440#ov

I installed Win 10 a few months ago and somehow (I literally have no idea how this happened) my clock speed reverted back to stock at around 2.8 down from the OC 4.0 I was getting before - sad, sad times.

I jumped on the forum and was informed that OC usually save a BIOS profile, so I checked it out and what do you know, the first profile was called "OCUK". Crisis averted.

Cut to today...

Last night I added more ram to my machine, these sticks to be specific: https://www.overclockers.co.uk/cors...l-channel-kit-cmx8gx3m2a1600c9-my-290-cs.html

These are the exact sticks already in my machine when I got the bundle in 2011, I figured play it safe and get another set of the same since my knowledge of hardware is pretty poor. So it's a basic jump from 4-8GB.

I popped the 2 new sticks into the empty 'blue' slots on the MOBO - tried to boot and...nothing. It just wouldn't boot - very odd.

The two grey slots were already populated with the original sticks - so i tried to swap them out for the new ones, leaving out my old ram sticks - boot success.

So the old sticks are out and just the new ones are in - then I added the old ones back, but instead put them into the previously unpopulated slots, the blue ones - boot success.

If I add the new sticks to the two blue slots - it doesn't boot. If I add them to the grey slots and move the old sticks to the blue slots - it boots. I would suggest looking at the picture in the above link to my MOBO if this is all very confusing.

Does anyone have any idea what would cause that? On boot I can see I have 8GB of memory running at 1600 - so everything looks good. It just will not boot with the sticks the other way around...not a huge problem but something I haven't heard of before.

This is a lovely story but seriously get to the point..

My OC profile has gone again...but this time it looks like it's gone for good. I booted up into the BIOS and was greeted with a message I've never seen before - something along the lines of "A recent hardware/voltage change has caused several boot failures..."

I checked my BIOS profiles to load in the "OCUK" profile and it's been replaced with "Defualt" which doesn't seem to be doing anything.

Loading up the OS shows the CPU back at a stock speed - I think I've genuinely lost my OC profile this time but not sure why/how this has happened.

- Does anyone know of anything I can try to get it back, do OCUK offer a point of contact for this sort of thing?
- If the answer to the above is no, what's the safest/easiest way to get by clock speed back?

Thanks in advance for any assistance on this.
