Specs: Windows 7, q6600 2
i have crucial ram but in order to run correctly it must be clocked to 4-4-4-12 but my acer motherboard has me locked out of the memory setting so my ram keeps blowing i need a bios version that will allow me to overclock my memory for a g33t-am-y2kc64-0100-001131-00101111-072107-bearlake mb

If the BIOS does not allow you to set your RAM manually, a BIOS update may not help. Many boards made for system manufacturers are slightly different than those sold separately and their BIOS are typically more limited on the adjustments. To be safe, you should ONLY get BIOS update from the system manufacturers website. An incorrect BIOS update can make your motherboard useless junk so using anything else is risky at best. It might be much easier to pop in the original RAM and go to Crucial's website and let them scan your system for your memory upgrade and tell you what you can use. Maybe they will be willing to swap the memory for one that will run on your board.

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.

The BIOS will read the SPD info from the EEPROM chip on the RAM & auto-configure the settings. OEM boards rarely allow the user to manually configure the memory settings. It appears you have a Q6600 which runs at 1066MHz FSB. If that's correct, you should be running DDR2-533 or DDR2-1066, anything else is less than optimal. BTW, my guess is you have an Aspire M5620.


I believe the following is the board the Acer is based on but you're taking a HUGE risk if you attempt to flash it with the ECS BIOS:


Here's the instructions for the Winflash utility:


"my ram keeps blowing i need a bios version that will allow me to overclock my memory"

What do you mean your "ram keeps blowing"? And why would you want to overclock your RAM? If you have DDR2-533 or DDR2-1066, no changes should be required but if you have either DDR2-667 or DDR2-800, you should be underclocking it, not overclocking it.

I don't think the board will let u underclock or overclock memory, if u have ddr 667 or ddr 800, find a ddr 533 (this will force ddr 800 or ddr 667 to run @533 ddr).

my ram is ddr2-800 it works fine then blue screens i've checked it with mem- test receiving memory errors i've replaced the ram 4 times crucial keeps replacing them for free i called them they said that the ram would keep going if i didn't adjust settings to 4-4-4-12 2.0v i've added a ram cooling fan for any heating issues also i've updated the acer bios but it didn't unlock the memory will this bios work on my motherboard heres my specksOperating System System Model

First, you should begin your own post for your own question ALWAYS.
Second, you should ONLY use BIOS updates from the system manufacturer (updating with any other BIOS, even one you feel 'should' work, can leave you with a motherboard that will be useless and unrepairable).
Third, your system supports Dual Channel memory so to get the MOST of your system you should always run your memory in matched pairs. You have 3 sticks of 2GB RAM when you should be running 2 or 4 sticks (see which sockets are paired together in your manual, often it is 0-3 and 1-4)
Fourth, you should contact Acer support about setting up your RAM in your system if you think that it is not optimized.

Running your memory at 4-4-4-12, which are 'tighter' timings than 5-5-5-18 which may be 'standard' should operate your system better but needs more voltage (usually 1.9V or 2.0V) than the 'standard' 1.8Volts. While I have a lot of respect for Crucial and their memory, I have had a set of their 4GB (2x2GB) 800DDR2 Balistix memory that have failed twice on two different systems. The first custom build I ran the memory at the stock 5-5-5-18 at 1.8Volts and began getting errors and shut downs which traced back to the memory. I replaced the set with another brand and sent those back for replacement. The next custom build I did I decided to use the replacements and on this one I ran them at the advertised 'custom' settings 4-4-4-12 but at 1.9 Volts (they did not need the 2.0 Volts to run at those settings). The system ran well for a few months and again the memory failed. I replaced them and again returned them for replacement. On both systems I overclocked the CPU but was careful not to run the memory beyond the 800DDR2 speed. These are performance memory and should be able to run at the stock and advertised settings, but were not. If needed, try a different brand (OCZ are running well at those tighter settings, but not all of their models list those settings I noticed).

You have to be a little bit crazy to keep you from going insane.
