Mobo: GA-Z68XP-UD3P
DDR3: 16GB(4x4) Corsair Vengeance CMZ16GX3M4A1600C9B
CPU: i7 2600K
PSU: Corsair HX850
GPU: EVGA GTX580
Cooler: Cooler Master Hyper 212 EVO
SSD: Corsair Force GT 120GB
HDD: WD Caviar Black 1.5TB
First off, this is a new PC build. I want to install my OS, but am having issues with getting any monitor signal while trying to boot with all 4 sticks of ram installed on the mobo; PC powers on but just no monitor signal. However, when only 1 stick is installed I am able to get into bios. I've been searching different forums and have only found some information on what to do. Some have suggested to manually set DRAM Frequency, CAS Timing, and DRAM voltage. Im sure someone has this mobo and memory and had success. Any help would be greatly appreciated and thanks in advance.

Welcome whitelabellt
Generally if theres problems from the onset of a new build ..... we/I suggest Memtest ALL modules one at a time.......10 passes each .... this way the integrity of the Dimms can be ruled out as the problem .... but for you ..... as you stated you can get it to boot successfully into Bios .... you could load the OS and generally configure the machine first off one stick and tackle the issue secondly .... Two choices! .... better then one! ;)

Hello Aussie Allan,
Thank you very much for you quick response. If I do decide to install Windows 7 first and configure the system, then solve the issues with ram, what exactly would I be doing to get this issue resolved?
Also, when you state to Memtest all modules one at a time, I am assuming you mean to place Memtest86 on a flash drive and test the ram? I am new to the world of custom PC builds, so I guess what I am asking for is a bit more detail on what exactly needs to be done.

"I guess what I am asking for is a bit more detail on what exactly needs to be done." ... Gladly given! ..... Memtest86 on flash drive is exactly the procedure .... once unpacked and installed correctly to the thumb drive ..... change the boot priority to the inserted key as you boot the machine up ....no one will argue with a dimm that has passed 10 consecutive passes ..The memorys top knotch so you should be fine with compatibility..... ... use slot one that your manual refers too only.
Once you have confirmed the memory's all good ...... As these are pretty good matched sets @ 1.5V it might be just a tweak of the Voltage to 1.55 or 1.6V (or higher)....hard to say just yet ..... if you tried the XMP profile ..... if there's a problems off the bat....usually recommended to input the numbers manually (Memory values) .... only critical thing to watch is never let the QPI/VTT (in Bios) fall below 0.5V of the memory voltage....can be higher but not lower ..... onboard controller on the CPU die can be damaged if you flout this point..... in a nut shell .... if you fill/populate all the dimm slots on most boards.....a little extra juice is required.
One of the reasons it's good to have the OS avalible once memtest is out of the way .... is so you can stress test with apps and get crash-dump/BSOD error codes if it goes tits-up.
Hope this helps ..... P.S .... grab a beer and read the manual again, ....it'll cut down the questions you feel you need to ask and make the fix quicker ;) :D

I interpreted this as you got no display signal at all (hard to run memtest with no display...unless you're monitoring the serial port); is this correct?

Right back atchya?
The computer works fine with one stick but not with four; what does it do with two?
If the first 64K RAM is bad, the PC won't POST; test them individually (or in pairs if you can).
If both pairs work when installed independently, try 1333 (or lower and work your way up), then install both pairs.

Now now ladies!
whitelabellt firstly you don't mention if you have installed a 32 or 64 bit version of Windows. Only the 64 bit version will see more than 4GB of memory.
The Corsair Vengeance RAM is very good normally and should run fine with your system. The only thing is that when you fill all the slots you put extra pressure on the memory controller and so have to compensate for that. After checking your sticks with Memtest86+ as Allan has suggested and assuming they all pass then you need to increase the QPI/Vtt value in the BIOS. Depending on what it defaults to you will probably need to try something in the region of 1.2 - 1.3v
You will probably get away with sticking to the default memory voltage but it is possible that you will have to increase that as well to maybe 1.55v.
If the first 64K RAM is bad, the PC won't POST; test them individually (or in pairs if you can).
The fact is that the computer does POST and so he can test his memory alright.

Care to enlighten me?
-
" Care to enlighten me?" ..... ;D .... I don't think anyone can or ever will! ;D .... you have to have some sense of humor Rolo ....
I'm not angry, have an Axe to grind ,... in fact I keep offering the olive branch ..... You do have some great knowledge tucked away in areas but I do find your use of words entertaining ... and no matter what .... never wrong! ...... that's what the hardy ha-ha was about .... no malice intended ... just humor :)

I can see both sides and I think that there is just a misunderstanding between the two of you. Just kiss and make up and then we can get on with helping troubled members rather than starting WW3. You both have plenty of knowledge and experience to share with others and there are plenty who could certainly make use of the added help. Thanks guys. ;)

Okie Dokie! ..... maybe the complements were misinterpreted now ..... maybe I should just send money! :D
Aussie Allan

Money is good!
I am quite prepared to act as a go between...just send all the money to me and I will look after it until I can pass it on! ;)
-
Hahahahahahahah .... Now that I WILL misinterpret ;)
-
You should!
All funds should be directed to me for distribution, I'm not sure how DM got confused? ;D
To the OP, can you boot with 2 or 3 sticks only? If so, then you likely just need to adjust some settings, QPI/Vtt would be first (maybe 1.15-1.3), then if that doesn't help you may need to increase System Agent (try up to 1.2, but try this last as it's normally not needed)
-
Fiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiine....now thats three on the list ...... please supply all relevant bank details including pin numbers and I'll get the funds moving from Nigeria. :)
Seems to have gone full circle .....now where back to QPI/VTT and mem voltage.....hahahahahahahah!

Sorry "My Friend" but all incoming transfers this way will have to be made via Paypal or Western Union :D
So, I didn't notice he already tried QPI/Vtt (Memory voltage changes were not suggested - by me anyway). Back to page one to cipher through that again :D
*Edit* Nope, doesn't look like he's tried the changes I suggested, but then again he hasn't replied in a few days either. Maybe we scared him off by playing around here? Hopefully not, it's all in good fun! :D
-
Agreed! ..... he didn't try my humble input aswell ..... could be in the process though and not yet posted.
And yes .... it is fun! ..... .... and paypal ..... Dam! .... haven't cracked that one yet! ;D

Hopefully he's just bee busy or out of town or something and will be back!
I love it how those spammers always say they are your friend, same as many tech support centers workers :D It's terrible how many people fall for stuff like that each year!

:o ....there's a difference! ...... I've got to read more!
