Hello everyone!

I want to change my BIOS Chip because my motherboard is locked overclock features because it was bought with a pre-built computer. I want to know If I buy a brand new flashed bios chip will it be unlocked.

Thanks

If you have a suitable BIOS, just flash it to the existing chip. You only need to replace the chip if you have bricked the machine or the chip has gone bad.

Mind, after trying to flash a new BIOS you may find that you need to replace the chip anyway if you get it wrong or use the wrong BIOS. ;)

I doubt there's anything you can do.

For one thing, even if you could which I've not heard of, pre-builts tend to not design the motherboards with the proper VRM's or other designs to facilitate proper overclocking which is why it's disabled.

Overclocking requires more power which would be beyond the design rating.

USAR, delete the older thread, thanks.

I just want to use XMP Profiles, because I cant enable them as I try to enable after rebooting the PC its like I never enabled it, and If I go to the bios again the XMP are disabled.

I think they were removable because theres lots of bios chips for those mobos, so theyre not going to sell a product which they know its unremovable.

You have to actually look at your motherboard via eyeball, and via the service manual.
Is that chip actually removable?

You 'think' it's removable, but you don't know.
The board did not come with a service manual. You can find this online somewhere.

You really, really need to find these things out before you spend money on something that may not work, or may not do what you want.

After looking at the images of the ASUS H87M-PRO motherboard at newegg, the BIOS chip indeed is the removable type, it's only pressed on, not soldered... so it is easily removable and a replacement will not be locked!.. that's for sure... well, unless you buy a used one that was removed from a prebuilt namebrand computer's motherboard :)

I also know a locked BIOS can't be overclocked, unless done by an official technician which would probably not be allowed to overclock a motherboard that's still under warranty, or be required to service one with expired warranty.... and overclocking software would probably not be able to do it without a service password. That said, how do you know it is overclocked?.

Unless you can find a modded bios, overclocking is not an option on the H87 chipset.
So changing the bios chip with a another chip with standard bios will not give you overclocking options.

In the original bios from Asus you need to turn on XMP profiles to use them.
You did not state what memory you have. Since this is a prebuilt machine the memory you have may not have XMP profiles. So there is no option to turn them on.

I cant find it, the only way I find it its in EZ Bios buts theres a problem, I activate the Profile 1 which is for my 9-9-9 rams I save & exit, I check the latencies with CPU-Z, theyre still running at 11-11-11, I go agai to the BIOS and XMP is disabled agai . Like ita not saving.

Do I need to have a K edition CPU to use XMP?

*Gskill Ripjaws X, they have XMP

XMP stands for "extreme memory profile" and it mainly affects the memory frequency and timings. It wouldn't be listed there if you couldn't use it so YES you can.

The BIOS must contain the profile for the memory so if it's too new it can't defect it thus you'd have to apply a profile manually. Having said that, I wouldn't expect you'd see the 9-9-9 profile if it didn't detect your memory in the first place.

It's possible that it's actually SAVING but on reboot the computer does it's POST (Power On Self Test) which includes a quick memory diagnostic; at that point it may decide it's not working properly and go back to defaults.

Depending on what CPU and memory you have, it might make little difference to change the memory profile anyway.

Another reason settings won't save is a DEAD BATTERY however that would default to factory settings so if you can change ANYTHING and have it save your battery and save feature works. Like onboard audio to OFF just to test then back again to ON.

Other:
In case I didn't say it or I missed it below, even if you could unlock the BIOS it's almost certain you don't have an overclockable CPU so I'm not quite sure why you wanted to overclock anyway.

You may be interested to know that DX12 games will minimize CPU bottlenecking. There aren't any yet though. Microsoft estimate up to 2X efficiency (meaning a dual-core would work as well as a quad-core with same architecture and frequency) but we simply can't confirm any of this yet until a few games come out later this year.

FYI, Windows 10 launches end of July (about two months from now) and it's a free upgrade from Win7/8. I'd wait until closer to Christmas to upgrade but I have tested it and I'm pleased overall.

This is a link to your manual.
In it states that the maximum memory speed supported is DDR3 1600.
From the manual.

*** Due to Intel® chipset limitation, DDR3 1600 MHz and higher memory modules on
XMP mode will run at the maximum transfer rate of DDR3 1600 Mhz.

Can you download CPU-Z and tell us exactly what memory modules you have?
If your XMP profile is for 1.65v the bios will not set it because Intel states that 1.5v is the maximum voltage for memory.
