I have a question/concern. I bought 2 sticks of Kingston RAM KHX1600C9D3P1K2/8G from Newegg. They will arrive tomorrow. I bought them because they are on the Memory QVL list. However, I did NOT notice until now that it says "DIMM socket support (Optional)" - "1 DIMM". Does this mean that I can only use 1 stick of RAM for my Asus P8Z77-V mobo?
Hi,
I have a problem with Corsair Vengeance memory on P8Z77-V. I have a 16GB set (CMZ16GX3M4A1600C9B) and when I stress test my system with just one stick of RAM, Prime95 custom blend test passes 12h without a problem but when I put 2 sticks in blue slots(recommended by user guide) it produces an error after a while (last time it happened after 15 minutes). When I put 2 sticks in black slots the error appears after around 4 hours. It also fails with 4 sticks plugged in.
I thought it was a memory problem but since each stick alone works fine I think it actually might be the motherboard. What do you think?
oh, I tried reducing RAM speed from 1600 to 1333MHz, as well as adding DRAM voltage (up to 1.65v). It still failed.
I use BIOS v. 1015
Trying running Memtest with each individual stick in the first DIMM slot, and then try with 2 sticks. That is the best way to isolate the problem to memory.
I have recently bought a P8Z77-V and i am having problems with the front USB-3 ports. My system is set up with 2 ssd,s one running XP-pro the other running Win 7, operating independently of each other using a boot manager. The first OS i installed was XP-pro and the front usb-3,s worked with this but after installing Win 7 they ceased to operate with XP but still work with 7. I have loaded all the necessary drivers from the support cd but its made no difference. Yesterday i started the bios once again to check if i had missed something and out of desperation i made the following changes:
1.Intel xHCI from enabled to smart auto
2.ASM1061 storage controller from enabled
dont know why, as i said desperation.
Booted into XP tried my usb3 flash drive and nothing, i had read somewhere on the net to try a usb2 device in the second front socket, this i done and it starts working so does the usb3 flash drive which i transfered files to to load onto win 7.
Closed the pc down returned about an hour later then on rebooting front panel usb,s not working again not even with usb2 flash drive. What is happening have i got a faulty board.
I have a Sabertooth Z77 and Patriot Viper Xtreme Division 4 16GB DDR3 1866 1.65v 9-11-9-27 memory
I updated the bios to 1206, the memory speed was 1333 so I went to bios and set that option from auto to xmp but pc started to BSOD on windows logo screen.
set all bios to defaults and tryed strating with 1 dimm with no luck so I had to do another clean install . i'm new to UEFI bios, what's the right way to set the memory settings please?
edit: here is a pic
To get this sorted I had to buy a seperate usb 3 front panel and run the cable from it out through the rear panel and plug it into one of the rear panel usb 3 sockets. I cant believe this mobo doesnt support usb 3 front panel from the 20 pin onboard connector when running Win XP. Saying that though it did at first, as i mentioned in my original post. This despite Win XP still being widely used.
Set XMP for the modules and try again.
Looks like a kit binned for X79 and not Z77, so the XMP profile is not really for this platform. To make manual DRAM timing adjustments enter the DRAM TIming menu within the AI Tweaker section of UEFI. Scroll down from where you selected XMP to find it. You might have to run different timings than what the kit is rated at, because the bin was not for this platform.
I have win 7 on another disk but dont use it as much as XP. I just cant think of a reason why the mobo doesnt support front panel usb3 in win XP, XP supports usb3. Stranger still why did it work with XP up until i installed win 7.
this is the memory, it says XMP Ready and Z77 and 1.5v though before they renew thier website it didn't mention Z77 and said 1.65v like here in Amazon.
anyway I changed auto to manual (and returned CPU turbo more to auto) and set the speed to 1866 and the timings to 9-11-9-27 and the voltage to 1.65 and everything is fine now.
btw, I had to disable surge protection because it turns off the pc when I run a game. I've been using the PSU in my sig since 4 years without any issues and don't know why the motherboard doesn't like it.
I started with XMP...
It wasn't stable on 1333MHz so I doubt that XMP (which sets memory to 1600MHz) would help.
I also tried increasing VCCSA to 0.975 (from 0.925)
A 4 year old PSU that has been run quite hard may have deteriorated somewhat. The surge protection kicks in if the rails are read out of spec at any point. Also, if you are using multiple monitoring tools that poll the SMBUS. If you are not (I would assume not while gaming) I would replace that PSU. That PSU needs to be checked with an oscilloscope to make sure it is functioning properly.

Hi, there! Seen a new BIOS 1304 for Sabertooth Z77 model. When will other P8Z77 models arrive ?
Raja?
I'm having a problem with my P8Z77-V Pro's onboard Intel 82579V NIC. It seems that it can no longer hold any connection faster than 10 mbit full duplex, and even then it won't get an IP address.
1.How to backup my current BIOS? My BIOS is version 0603. I search in the ASUS Update in the AI Suite but there is no option to back up my current BIOS.
2. Do I have to format my USB flash drive to FAT32 first?
3. Can I have two version of BIOS in single flash drive?
4. In the manual it show 4 method to update BIOS.
a. ASUS Update
b. ASUS EZ Flash 2
c. ASUS Crashfree Bios 3
d. ASUS Bios Updater.
Which one is the safest and easiest?
If you are on the latest BIOS as well, then maybe try out an RMA. If you are USA based you can ask for cross ship if you put down credit card security.
Have you run the diagnostics? You can get to it from Device Manager Properties for the NIC, then the Link Speed tab. There's a button called "Diagnostics..."

Try the newest version of the BIOS. I tried using that RAM when I first got my Deluxe when it first came out, and I couldn't get that RAM to pass testing (with 2 different 16GB kits), but other RAM worked fine. So I ended up returning the RAM and commenting on it on Newegg. I got a reply to my comment from Corsair saying a new BIOS addressed the issues with the RAM. Dunno if it's true or not, but I'd definitely try the latest BIOS, and if that doesn't work...may have to look at other RAM.
I plan on doing a build with the Asus P8Z77-V Pro and was wondering how good the onboard sound is?
This is mainly going to be a gaming rig and i am leaving a 5 year old Gigabyte GA-MA790GP-DS4H board with a Sound Blaster X-FI Elite Pro card. Would the onboard sound be good enough that i wouldn't have to buy another sound card?
Opinions?
I plan on handing this computer down to a friend. Maybe i'll have to grab the soundcard out of it first.Why change the Elite Pro Creative to shtty onboard?
I plan on handing this computer down to a friend. Maybe i'll have to grab the soundcard out of it first.
But, the only sound i get from my computer is through the headphones anyway. Still make a difference?
1401 BIOS was posted for P8Z77-V Deluxe - http://station-drivers.com/page/asus/asus_p8z77_v_deluxe.htm
Sabertooth Z77 - http://station-drivers.com/page/asus/asus_sabertooth_z77.htm (don't be affraid the upper BIOS not 1304, it's 1403... Just move your cursor on the link and you will notice that it's a site syntax mistake)
Will there be such BIOS version for P8Z77-V and P8Z77-V Pro?
Raja?
Same as last time. If they need the updates they will get them. If they don't, they won't.
