ASUS P8Z77 V Pro sees only half the RAM

[Hell_LordBR]

Hi,

this post is pretty old but i guess many people will have the same problem when they update to a newer version of the Bios (2104 for the asus P8Z77-V pro)

Basically it happened to me as well and this post did not really help. I spent my Saturday afternoon trying to find the bent pin that would be responsible for this but nothing worked. I re seated the processor many time without success.

But finally i found the problem and the solution. All credit goes to coderush and his very good post from 2012.... You can find it here http://hardforum.com/threads/tools-...-on-asus-p8xxx-boards-fd44editor-ftk.1726429/

The symptom for my system were:

• Only see 8 Go of Ram instead of 16 Go even if Cpuz saw 16 Gb
• No more internal video card
• No more access to overclocking option and CPU ratio locked to 35

What i noticed is that with the new version of the bios i would get a different version of the ME between my bios backup and the bios downloaded from the ASUS website. The ME or management engine is the intel chipset firmware. Turn out it was not update with the flashing of the new bios
I followed the instruction from coderush and after a reboot everything was back to normal.

I hope the poor soul that will find this post will directly click on the link to the hardforum since it will save a lot of time.

Thanks and bow respectfully to coderush!

I have to say many thanks, you saved my Asus P8Z68-V Pro, i had a problem with the mobo only finding 8gb from my 16gb ram, and any overclock on my ram would make my system won`t boot.

Them I downloaded the last bios from asus`s website (the very same that i already had installed on my mobo), renamed to bios.bin, booted dos + FTK from my flash drive and ran merefl, then did a poweroff command.

Magically eveything works now!!!
You and CodeRush are aweasome, many thanks from Brazil!

I was having the same problem with my MB only using half of the memory it detected. I used the FTK method I found in this forum and it worked like a charm. I was at my wits end. I knew the MB itself was not faulty. I knew it had to be firmware. Thanks guys!

Hello!

In the last week my computer started displaying 8GB RAM when I have 16GB installed.
I only noticed when the machine was running slowly and I checked in task manager. I had noticed a week or so before that the iGPU option was missing in my BIOS but hadn't used it in a while so figured maybe it went with a bios update or something and didn't think much of it.

Anyway, I'm on the P8Z77-V Deluxe and found this thread.
I know all the memory sticks are working as I have cycled them through all the slots but still only get 8GB.
CPU-Z shows 16 as is the case with others in this thread.

I had a look at the thread on hardforum, and I tried to follow the instructions however I haven't really got anywhere.
A lot of it seems to be that the BIOS file I get from ASUS is a CAP file not a BIN file. I looked in to this and found an ASUS Bios Renamer (or something?) utility but that just renamed the file, keeping the format as CAP.
I tried changing the file extension (probably a bad idea in hindsight but it didn't break anything) but that didn't work.

Basically I'm wondering if anyone can help me with some more straight forward steps that are relevant to my specific issue?

I've got a bootable DOS USB drive and copied the extracted FTK folder to it (which itself contains FTK7,8,9,10) and I've got the BIOS CAP file on the drive but i've not managed anything successful beyond that point.

Any help would be really appreciated and if I've missed anything out or you need more information just let me know!

Thanks!

Make sure the cpu cooler isn't mounted so tight it is flexing the motherboard.

Take all ram out and clean the ram slots, do a clear cmos on the board, make sure to match pairs of ram to a pair of slots. Enable XMP/DOCP and start with lower ram speed. After a certain cas level the ram can't be detected fully at certain clock speeds and capacities.

Are you using 2 different Brands of ram?

Hi,

I read through the thread so i've checked the RAM (it's all one brand and type, bought 2 sets of 2 sticks at the same time).
Checking the CPU is trickier. As with someone else in the thread, I'd have to basically gut my PC to get it out because of the CPU cooler but I guess if I have to then I will.

I'm pretty sure from the sound of it it's the BIOS issue that people have had though and it'd be less hassle to try that than reseating the CPU (and if it doesn't fix it and I do need to reseat the CPU/check the pins) then it won't make things worse!

The thread i'm having trouble following is https://hardforum.com/threads/tools...-on-asus-p8xxx-boards-fd44editor-ftk.1726429/
It's quite an overwhelming post to try and follow (it covers a lot of bases) so I'm hoping maybe someone will be able to trim thing's down to what i would need to do to attempt this fix for my particular issue?

Thanks for the reply!

Basically the easiest thing to do in any system is to breadboard it. I know it sounds like it's a tedious task but it helps isolate your troubles a lot easier.

It is also easier to see all components when out of a dark case

Check for bent pins on the socket or you have a bad IMC. I had this issue with a board about a month ago and 1 pin was a little out of whack. I took a needle and propped it up and bingo, Liftoff.

I had this issue with different boards long ago - from P35 to X58. Bend pins would lead to RAM detection problems.

You need the bin file(latest bios) and the brenamer on a desk top, then put the new bios in the brenamer file. Then open it in the file, it basically changes the extention from a bin file to cap file. But you need to also name the bios correctly like" P8Z77 V-Deluxe F6" or what ever bios revision it is(F6 replace with proper revision). Then place that file on a bootable jump drive, boot to bios and update it. Then after its done, load bios default setting upon reboot. Then aim it at the proper drive to boot from...

So many thanks all of you!

From 2024 it may sound strange but my PC on P8Z77-V LX still works well. I just replaced RAM with four 8GB banks to have 32GB... and see only half of it

I followed these instructions but in 2024 most of provided URLs don't work. So what I did to get it work:

• I've updated my BIOS with "P8Z77-V LX BIOS 2204" firmware cause version 2501 can't be recognized.
• GitHub project is available still, but it requires additional files: FPT, fparts.txt, MEInfo and FwUpdLcl + bios.bin that is renamed file mentioned above.
• Thoose files can be foud in ME System Tools v8, that I found on this page in section "C2. (CS)ME System Tools".

Thanks a lot again!

That person hasn't been on for nearly a decade.

Wow, here we are on 2024!
im glad that worked for you
