Z77A-GD65 - add more voltage to DDR RAM?

Greetings.
I'm trying to OC my ram from 1600Mhz to 1800Mhz. My ram runs at 1,5V 1600Mhz, and I want to add a little more voltage to the ram for stability. But in BIOS under the setting of Voltage for ram the setting is locked at "auto".
Which setting in BIOS must I change to unlock "DDR Ram Voltage" to raise it a bit?

Yes
Thank you very much

Z77A-GD65 no longer boots with 4 RAM modules

I had 4 x 8GB Cosair Vengeance LP that used to work fine, but no longer boots into Windows with 4 but only with 2 RAM modules. Any help in solving the issue would be appreciated. ( I need 32 GB as I run many virtual machines )
The 4 modules worked fine for few months until couple weeks ago, when I saw issues with booting into Windows 7. The workaround was to "warm up" by leaving the PC in BIOS for about 5 minutes and it would boot fine. Since couple days ago, it would POST but not boot into Windows or into live Linux on USB, so I started troubleshooting with bare bones first ( MB, CPU, 1 RAM, PS ) and then starting adding more and more components until I found that 1 and 2 RAM modules worked in either black or blue rail but with 4 RAM modules, it will POST, but not boot at all into either USB based live system or into Windows 7.
Memtest with 2 separate sets of modules pass with flying colors. Mixing the sets work fine too, but add 2nd set (i.e. 4 modules) and it fails to boot. I am leaning more toward believing the issue is with the MB than with the RAM since mixing them doesn't throw any memory error.
Any suggestion on how to check if it's the RAM or MB ?

What voltage is the RAM running? A slight bump up in voltage might help.
As to voltage, I started with standard 1.5 and then incrementally upped it to 1.65v. At 1.6v and above, it does boot into Windows, but intermittently goes into BSOD... Works perfect with 1.5v with 2 RAM modules.
I'll save the money for next build instead of going for 32GB kit. ... guess I'll live with 16GB for now.
Thank you all for the advice.

Z77A-GD65 mixing two DDRAM pack, same brand with same parameters problem

Hello. I have question. My mobo is z77a-gd65. I have 16gb of ram. Is it pack of 4x4gb modules from corsair vengeance lp (CML16GX3M4A1600C9). Because one module is damaged (tested in memtest) i buy new pack. This new pack is absolutely the same as previous but only 8gb (2x4gb). Is it same brand and timings (CML8GX3M2A1600C9). My problem is.. i can not enable the xmp profile in bios. This option is not accesible if i use 2x2gb from first pack and 2x2gb from second pack. Next problem.. if i change the ddram frequency manually to 1600mhz (from 1333 - detected whith bios) which is default fq after save settings and restart, bios automatically set frequency to 1333. I try use oc genie but the same and no luck.
Is not possible use two different memory pack from one brand with absolutely same parameters? Why i cant use and is disabled xmp option? Why bios automatically changing ddram frequency?
Thanks.

Corsair warns of mixing RAM even with the same exact part numbers. Best thing to do would be to contact Corsair and ask them to replace what you have with a factory matched and tested RAM kit. I have heard they are very good about doing that for the end user.

Boot issue with Z77A-GD65

I have a Z77A-GD65 board with 16GB of DDR3 RAM (4x4GB DIMMS) and an I5 Ivy Bridge CPU, Samsung 830 128GB SSD and 2x 4TB HDD's.
Last night my system was working perfectly. Today it won't boot into an OS.
When I would power up the system this morning, it started went through the Intel Matrix RAID BIOS fine then did a few status codes in the bottom right and ended up on A2 as the current code and sat there forever... I let it set for 15 minutes about no change.
I pulled the HDD's and SSD off first, same code
I pulled the USB and ethernet now the code changed to D0 still nothing, just hangs there.
I switched the BIOS switch to the second one, same result.
I pulled the BIOS battery and power and let it sit for a while, plugged it back in and put the battery back in... same result..
What's going on? I'm not sure where to go nor do I know the exact meaning of the codes given

what is your bios version?
The BIOS that went nuts was A.B0, I did get it to boot though, just not with that BIOS...
I pulled all the cards, all the memory, anything plugged in HDD/SDD etc.. only thing left was onboard DVI and keyboard... cleared the CMOS again with the back button and it went into a never ending reboot loop.... switched it to the second bios via the switch on the motherboard, cleared the CMOS again, and bingo it booted... I think that BIOS 1 is corrupt... not sure what caused it, haven't done any updates or anything since A.B0 came out. And haven't made any hardware changes in that time either... worked great until this morning turned it on and boom It was stuck at A2 on the BIOS startup.
My question now is, how do I reflash BIOS 1? I read somewhere before I think that I have to do a multi bios update, but not sure how to go about doing that.

Z77A-GD65: Disks shown but not selectable on creating a RAID volume

Mainboard: Z77A-GD65
CPU: Intel Core i7 3770K
RAM: 2x Corsair DDR3-1600 XMS3 4GB
HDDs: 2x Seagate Barracuda SATA3 7200.12 6GB/s
Upgraded System with new MB etc. yesterday and removed the old HDD.
After enabling RAID in BIOS, I went to the RAID settings with Ctrl+I. The RAID setup displays both HDDs with correct description and storage size, but when I was trying to create a new RAID volume the "disc selection" option is not selectable unless "Recovery" is chosen as RAID level. On RAID level "Recovery" both disks are selectable but no RAID volume is created during the process. When RAID level 0 or 1 is chosen still the correct size of the potential volume is calculated by the RAID setup.
Additionally, I tried the same procedure with both "RAID hot-plug" enabled and disabled in BIOS.
The HDDs are plugged into SATA-ports 1+2. No OS installed yet.

After several unsuccessful attempts of formatting and partitioning the disks, I installed the OS. Subsequent use of the thereafter installed Intel Rapid Storage Technology (IRST) enabled me to created the RAID volume under Windows, which is now additionally shown on the IRST page after the POST screen.
So the RAID volume creation worked, but it still takes me wonder why I haven't been able to do this after the POST screen in the first place .
Well, problem still kind of solved.

DDR3 RAM specification for MSI Z77A-GD65

Hello MSIers ,
I am about to buy the MSI Z77A-GD65 or GD55 not sure yet ... I used Gigabyte boards for 10 years and they always state to use 1.5 volt RAM sticks ...
Now for MSI and the mention board , what voltage should I pick ? I want 2 sticks of 4GB DDR3 1600MHz and might look to faster frequencies like 2333 MHz ??? will it work with an I7 3770 right out the box (if I load XMP in BIOS) ? can lower latencies or CAS as well ?
Thanks

Allot of the mushkin comes pre-under-timed (the xmp profile does anway) As that computer is an AMD platform, I need to match the xmp profile and adjust the fsb/ dram ratio to get the correct speed & timings. Both of those listed computers are quite stable.
The corsair memory I have listed has an xmp profile of 11-11-11-30, I manually under-timed that when I was tweaking. That is the lowest I could go and maintain stability.
One thing to keep in mind when you look at memory, is that almost all that you see out there is 1333 memory which has been tested and tuned (Overclocked) to w/er limit. Even ddr3-1600 you buy will by default run at 1333 as the 1600 is an XMP profile extension to the SPD. So no matter what you buy over 1333, you are most likely going to need to at minimum enable the xmp profile or at worst tinker with the speed & timings manually.
Nice .. Thank you ..
So what DDR3 freq. / timings you suggest for the best performance and stil very stable (as long as I (most likely) need to tinker a bit around the BIOS and XMP) ? I am gonna use the I7 3770 locked version CPU
You advice or against , maybe 2000 freq or more DDR3 with the Z77AGD65 ? or you advice with choosing a lower latency modules but at 1600 MHz freq like this http://www.mushkin.com/Memory/Redline/997056.aspx ?

Z77a-gd65 voltages

hello i have the z77a-gd65 and was wonderring if i should rma it as the voltages in control center says the 12v is down to 11.792. i have a corsair ax1200i and the link software says its sat at 12.000 to 12.100. is there a problem with the sensors on this board or is it just the control center.i have bios v10.0. i dont know if its a bios thing and dont know what iam doing to flash bios to see if that fixes it any help would be nice thanks

Ok one more thing I should of said is I had the same problem with MSI p67a-gd65 b3 with the same voltages. I sold the p67 to my brother and the voltages are correct now. Could this be down to my Intel I5 or could it just be the bios needs updating. Last night stripped my pc down to motherboard diffrent ram and CPU and cooler no change in voltage at all any help welcome

Z77a-gd65 bios/ram

good day to everyone.
first of all here is my spec:
i5 3570k
16Gb (4x4) Corsair vengeance 1600Mhz CL9
z77a-gd65
bios 10.10
problem nr.1
i can't make RAM working faster than default-1333.
i read lot of forums, where ppl able to do changes from 1333 to 1600. but i can not.
problem nr2.
it was only AUTO in timing (few month ago i was able to change numbers. i did nothing with bios, it just became AUTO by itself)
my i5 was working @ 0Mhz !!!
fixed by downgrading bios
i'm wondering... should be number like here?
is anybody can help me? how to make RAM working @1600 and more?
will be nice to receive step-by-step guide (better in pictures)
thank you
ps. sorry for not super English

Remove and re-seat all of the components outside of the case on a non-conductive surface. While the cpu is removed, inspect the cpu socket for any bent or mis aligned pins.
Perform a full cmos clear and re-test with only a single stick of ram in DIMM 2, cpu, cooler and psu.
...now my pc is in non stop restart... lol. all i wanted its only make ram 1600.
done. i switched off oc genie and change settings in "standrd" mode. all 4 sticks of ram are working together.
thank you for help.

Can I add more ram than suggested

I need to get some more ram for my imac that apple say I can expand to 16gb. I currently have the standed 4gb.
In the following article from pcworld i noticed the following (especially the bold)
All iMacs come standard with 4GB of memory, installed as a pair of 2GB modules. When you order an iMac through the Apple Online Store, you have the option to upgrade the memory to 8GB (a pair of 4GB modules) on all iMac models for $200, or to 16GB (four 4GB modules) on the 27-inch models for $600. The iMac has four memory slots located at the bottom of the iMac that are user-accessible. Since two slots are empty when you buy an standard-configuration iMac, you can easily add more memory. The 21.5 inch iMac has support for up to 16GB of memory; third party companies are offering 32GB memory upgrades for the new 27-inch iMac.
Does this mean that I can technically go up to 32gb? Is there a down side to adding more the an 16gb suggested.

Although you can install up to 16 GBs of RAM in both 21 and 27" models, I can not confirm that you can install 32 GBs in the 27" model. You might check OWC to see what they say.

How do I add more RAM to my macbook pro 15 inch late 2008 model?

I am wondering if I ma able to add more RAM to my 15 inch MacBook Pro from late 2008. It currently has 2 slots each with 2GB of RAM each. Am I able to change those out with higher amounts of RAM for each slot? Or is this thing maxed out and i'm out of luck? Any info would be much appreciated. Thanks!

Z77A-GD65 ram and DR. mos problem after 2 years without any HW change or OC!

Hi guys, i have three Z77A-GD65 from 2 years with the same hardware config, no overclock or others OC settings ....simply default bios settings; in this last 2 months, not at the same time, all of my 3 mainboards have the same identical problem.
One day, from nowhere, without any reason, i start my pc and mobo don't start, hangs with code 55 ( memory error) and Dr mos alarm led goes on, i try to reset bios .. nothing.
I Switch multibios to "B" bios and works perfectly .. i've tested all of RAM modules and result works perfectly !! .... all of three mainboards have the same identical problem!!
Now i use all my 3 PCs with "B" bios and works perfectly, because "A" bios hangs always with code 55 and with Dr. mos alarm led on, i try to update and downgrade "A" bios ... nothing to do ... "A" bios don't work anymore.
Any idea?

Don't have to be rude
If same problem is on 3 motherboards then is something wrong with RAM or BIOS not the motherboard
>>Posting Guide<< Reminding again if you want to receive any help.
Nichrome, you misunderstood! ... I just responded to your affirmation .. that's all, it was not my intention to was "rude" as you wrote! OK?
Ram modules have been tested on other Asus mainboard .. .. no read/write errors and no hangs problems ... so all Ram modules are fine
About bios ..... maybe primary bios is physically damaged.... i try to reflash bios also with old version .. no way .. maybe primary bios damage in all 3 mainboards !! very strange!!! ... you know if there's a know manufacturing defect on this MB bios maybe on a particular MB serial part number? because i bought all 3 mainboards at same time about 2 years ago.
Quote from: Sea Dog on 19-July-14, 02:40:52
Obviously, there is 'something' that has caused BIOS corruption in all 3 mainboards A chips. Whatever that 'something' is, it may happen to the backup B chips as well. Recommend to concentrate on finding this 'something', what the common denominator is, and restoring BIOS chips A before the mainboards may become expensive paperweights. A shop with an SPI flash programmer device can fix the broken BIOS chips if not comfortable with doing the recovery procedure yourself.
Hi, yes i agree, In fact, my fear is to have, in a while, these mainboard totally unusable! ..... i think that primary bios is physically damaged or i hope, software damaged, I would try to recover it, if it's only a software problem (i hope so) ... do you know a procedure to completely erase cleanly that reflash the primary bios? i try to use dos MSI flash utility with "/p /b /n" options .. no success to restore A bios ... same story ... error 55 and DR-mos alarm led on.

Equium A100-303: looking to add more RAM

Hello,
I recently bought an A100-303 equium notebook and am lookin to add more RAM. I was just wondering if it needs to be buffered or unbuffered or does it matter?
I currently have 1gb of ram (512 + 512 as its a dual core processor) and am looking to upgrade to 2gb (1024 + 1024). I know the type is PC4200, 200 pin, SODIMM.
Also where would be the cheepest place to buy these? Thanks.

Hi
> was just wondering if it needs to be buffered or unbuffered or does it matter
Well, Toshiba recommended using own memory modules like PA3411U-2M1G but I dont find any information if the module supports ECC (means buffered) or Non-ECC (means non buffered)
In my knowledge the ECC-buffered memory is about 30 percent slower as the Non-ECC modules.
Its your choice what you will buy but I would recommend buying a brand name module.
I know, the no-name modules are cheaper but brand modules are much faster and the performance and quality is better as no-name modules.
So googel a little bit and you will find many online offers. Compare simply the prices
