I have just purchased the new parts to build a new PC but have run into a few problems. I have been building PC's for more years then I can recall so I am not a newbie but I have never come across this problem before. 

 

The main bones of the system is;

 

Gigabyte Z77X-D3H motherboard

Intel I5 3750K processor

2 x 4GB Corsair XMS3 DDR3 1600 C9 1.65V memory

Zotac GTX670 4GB graphics card.

XFX 850Pro power supply

 

When I first installed the parts I got 8 short beep, 1 long beep, 2 shorts beep and no post display. I checked google with no joy so phoned Gigabyte. They said that the board could need the bios flashing so it could run an Ivybridge CPU so I sent it back RMA. They sent it back saying no flash needed with photos of the board running an Ivybridge CPU, all memory ports full with onboard graphics and PCI-E graphics.

 

On return I set it up again with the same beep codes. I returned the CPU for a replacement and received a new one but still had the same boot results, none. I then went and changed the memory for 2 x Ballistix Tactical  DDR3 1600 C8 1.5V memory thinking that the 1.65V was too much for the Ivybridge CPU. This resulted in the motherboard giving a continuous beep (no memory installed). I have tried a Bios reset, different sockets, with and without the GTX670 but still no joy. I have tried the power supply on my old I7860 system which works no problem. I have tried the memory on the i7860 system which also works.

 

Has anybody got any idea's as to what the problem could be. As I am loathed to spend more money just trying things as it cost me money to send bits back all the time.

 

Thanks Craig

Sounds like you've swapped everything out except the MB. That might be the culprit.

That's what I thought but I sent that back to Gigabyte who sent me photos of the board running Ivy bridge processor ok, booting into Windows 7.

Try one RAM stick at a time. And one RAM slot slot at a time

Did you send the board back to them with your ram or did they use there own ram ?

Those beep codes are there to tell you whats causing the problem. What does the book say regarding the beeps?

 

Does the board have a small LED display with a code? That's a good place to start as well, should give some info regarding the problem.

 

Try without the case, maybe you have a bad ground or something is shorting on the back of the motherboard.

 

Make sure you have power going to the CPU fan!! Can't tell you how many times Ive seen this.

 

Good Luck!

"maybe you have a bad ground or something is shorting" that happened to me when I was a rookie lol - for instance the small hardware riser that connects from the motherboard to the case was grounding out.

It's a BIOS and hardware problem, maybe.

 

The MB manual has a trouble shooting section that will tell you exactly what the beeps mean. Going in order and from memory, and remembering what they mean should they typically be the same, it sounds like you have a memory RAM-I failure issue, a circuit failure somewhere, and a VGA issue. However, it could be a single parity issue and not all of them. So....

 

1.) Make sure the Mobo isn't touching anything it shouldn't be. Sometimes a CI will occur and the MB will use it's internal safety systems to keep it from firing up.

 

2.) Unplug the monitor and boot the rig up. Listen for the beep sequence.

 

3.) If you still have your old GPU, toss that bad boy in there and see if the machine will boot.

 

4-1.) Keeping the rig as is, remove the 670 and see if it boots into Windows with the onboard video card. If it does, then you can start trouble shooting your problems from there.

 

4-2.) IIRC, if you're running Win7 (64 bit) you should only need 2GB of RAM, so remove and stick and boot it up. Again if it does boot up, you can start trouble shooting from there.

 

 

Conduct steps 4-1 and 4-2 independently of each other!

 

EDIT - If you are still in a fix let me know and I'll run through the more time consuming TS routes.

Thanks for all the advice but have already tried all that. Like I said I have been building PC's since PC's had a turbo button. Have tried the board sitting on the cardboard box, with and without memory, with one ram stick in each socket, with two ram sticks in dual channel sockets. I have tried it with onboard graphics, my GTX 670 and both of my old GTX460's I have tried my old memory, new memory and even newer memory. I have checked all power connectors, unconnected and re-connected. I have even tried both 4 pin CPU power connectors from my motherboard.

 

The manual gives no beep codes and a list I got from Gigabyte shows no codes similar to the ones I get. The closest I can find is 8 beeps for video memory problems. There are no led codes on the board unlike my old ASUS Board, at least that gave you an idea where to start.

 

Is anybody running an Ivy Bridge CPU with 1600 memory because the ones that Gigabyte tested was 1033 speed. Other that that I only have two conclusions left. The CPU's are all from the same dodgy batch or the board has an intermittent fault and needs to go back to Gigabyte.

Sounds like you know your stuff but you did not answer my question this is important if they used Their ram that might be your problem not all ram plays on all motherboards nicely pain but it is what it is.

 

Did you send the board back to them with your ram or did they use there own ram ?

 

How about trying another keyboard

Ah man...

 

Well, at least you know you GPU is good to go then. If you've toyed with the RAM options, then I'd say you have a bad mobo.

 

Have you tried Memtest?

They used there own Ram Richard, that's why I am wondering if the 1600 speed is at fault. I bought 2 x 4gb of XM3 DDR3 as I already had 4 x 2gb Sticks of the same type in my old computer. Was going to take two sticks and use 2 x 2gb and 2 x 4gb to give me a total of 12gb. I have tried all 4 of the 2gb, both 4gb and the two new Ballistix sticks but no joy. The XM3's give me the 8-1-2 boot code, the ballistix give me a no memory continuous beep. But I know that the XM3s work no problem but all the ram I have is 1600 speed.

 

I am going to take the board, ram and CPU to the shop I bought the Ram from and hope they will try a different CPU. If that works then I can put it down to the CPU, If not then I think I will have to send the motherboard back to Gigabyte.

 

This rebuild was supposed to be cheaper then buying a whole system but at this rate it's going to cost me more with the postage sending things back.

Sorry for all the heartache I choose gigabyte because I am able to call them try doing that with asus lol - I would think its your memory even though you have tried others not a perfect world but if they got it working with their ram I would put money on the ram being the problem on your end also did some reading that an older bios with your cpu may not be supported you need to update that bios asap V7 I believe is the latest. I would somehow try to find out the ram they used on that MB check. You mention speeds on ram as you actually have to pay attention to the brand of ram you are using very important I have run into this myself and now when buying ram for a new build I do my homework big time when it comes to my choice of ram.

Just one thought - have you tried changing the psu? ie using a different one?  Changing the leads, etc.  Is it a modular psu?

In your original post you have your processor listed as a I5-3750K. Checking Gigabytes main website for the GA-Z77-D3H motherboard CPU support list does not show this processor, I suspect this is just a typo and you may have a I5-3570K , is that correct? If so you need the F-18 BIOS can you confirm your BIOS? Are you able to get in to the BIOS screen? Also the Gigabyte specifications for that MB show 1.5 volts for non-ECC type memory modules as being listed.Try setting the memory module voltage to auto.

 

Here's the link for the Gigabyte GA-Z77-D3H website:            http://www.gigabyte.us/products/product-page.aspx?pid=4327#sp

 

and for the CPU / BIOS support list:                                        http://www.gigabyte.us/support-downloads/cpu-support-popup.aspx?pid=4327

 

you'll also find the downloadable memory support list link there as well.

 

My apology's if this is information you already possess.

 

By the way I'm running a I7-3770K on a Gigabye GA-Z68X-UD3H-B3 with 4 x 4GB /1600 Corsair XMS3 memory modules at 1.5 volts with F-12 BIOS and it's running great. I haven't tryed OCing it yet so my voltages are set to auto. Hope you get it solved and can start enjoying your new setup soon. Best of luck Vecter.
