possible use full 4 Gb ga-h55m-s2hp

[Hqxriven]

Intel i5-750 Gigabyte ga-h55m s2hp, F3 and F4 (latest BIOS)
XFX GTS 250 1GB
XFX 750W PSU
4GB of GEIL (2x2GB DIMMs) - rated DDR3 1333 1.5v

Tested with value Kingston and Coursair and the problem persist

I bought a motherboard ga-h55m-s2hp and unfortunately she is not using the full 4 Gb system perfectly in a 64-bit only 3.8 GB

Memtest does not accuse errors

I'm using the i5 750 and a video card offboard and the bios continues reserving memory even with video offboard.

In the bios detecting 4Gb is made, but upon entering the system 64-bit operating it incorrectly reserve memory.

The problem I have occurs in other motherboards from gigabyte with other users

***Gigabyte H55/H57 motherboard discussion*** - Overclockers UK Forums

GA-H55M-UD2H & 4GB memory

This decreased my performance since it does not i use the full 4 Gb of dual channel only 3.8

Test all the hardware with other ga-h55m-s2hp and the problems persisted

Test all the hardware with another motherboard (ASUS) and no problems and pins are no problem, which demonstrates that there is a defect manufacture this motherboard or bios.

I hope my problem is resolved as quickly as possible because I'm a customer and like the gigabyte mark and I remain a customer.

Sorry for bad English.

Re: possible use full 4 Gb ga-h55m-s2hp

i think its normal for it to reserve 120mb for hardware like onboard graphics even if you have a graphics card installed,asus boards are different,maybe newer bios will fix this? i dont know

Re: possible use full 4 Gb ga-h55m-s2hp

This can not be normal. This is a failure.

Possibly a flaw that was not observed in tests and can be fixed by a bios update.





Note well the "Activates the onboard graphics only if no PCI Express graphics card is installed"

And still reserving memory for activation, the problem is here.

My processor is an i5 750 and it has no VGA on it.

Please send in a report here guys
Technical Support - GIGABYTE

Have you cleared the CMOS for an extended period? How about update the BIOS with Qflash, and disable "Keep DMI Data"?

[Hqxriven]

Re: possible use full 4 Gb ga-h55m-s2hp

Always with Qflash!!

Report done

[Lsdmeasap]

Re: possible use full 4 Gb ga-h55m-s2hp

Keep DMI Data disabled as well?

Let me know what their reply back is.

I know some other users as mentioned above also had some similar issues and GIGABYTE Tested and sent me images of it working properly, yet those users still had issues so not sure what the problem is?

Re: possible use full 4 Gb ga-h55m-s2hp

I followed this tutorial:

I know some other users as mentioned above also had some similar issues and GIGABYTE Tested and sent me images of it working properly, yet those users still had issues so not sure what the problem is?

There are two possibilities:

Works

If the images show that gigabyte card with another bios and make available the same and recognize all the ram on my machine here know what the problem was simply the bios and continue with my motherboard.

Rubbish

If the images show that gigabyte card with the same bios or other functioning properly and that does not work I be sure that the problem is the motherboard and can not be corrected.

Possibly a bad batch problem, some kind of defect on the motherboard or some type of failure, whereas the asus boards and other work normally.

Also because I tested two processors, 3 memories and 2 video cards that work fine on other machines (even though my friends helped me)

Arrive at this conclusion.

Re: possible use full 4 Gb ga-h55m-s2hp

Well the image I mentioned is this post, where I contacted them directly and they setup a test platform and had no issues. BIOS version is shown

Let me know if support does not get back to you in a few days

Re: possible use full 4 Gb ga-h55m-s2hp

The problem is that my motherboard is produced in Brazil it is not even on the international site of gigabyte.

Maybe that's why has not the quality standard gigabyte, maybe even be problems in the material used (recently problems with sockets foxconn which was revised up to what happened with several brands, but how many people and shops have version problems yet? ?).

So I think it will be difficult for them to have this card s2hp there (might have to leave one here in Brazil to test and perhaps that traveled here have had this problem corrected or another review).

Never had a problem with gigabyte that could not be fixed with bios update, with the help of the support that is affordable and has quality or even having to do a rma (but then bought another gigabyte).

Besides, I always recommend the gigabyte

Qual mobo soquete 1156 na faixa de R$ 250-350?

So I have a brand preference gigabyte and if all goes well I intend in September to buy another motherboard to get more resources (GA-P55A-UD3 (rev. 2.0) - GIGABYTE # ov)

I'm just waiting for the solution ...

Thanks for the help Lsdmeasap!

Re: possible use full 4 Gb ga-h55m-s2hp

Does the PCB say made in Brazil too?

I agree, if it is a BIOS issue I'm sure they can fix it. I don't have your exact board, but I do have a H55N-USB3 that I plan to test this with for you. I'll check with a CPU with onboard GFX, with it disabled and then enabled, then I will also test with a CPU without onboard GFX. If I see similar issues then we'll know it's due to a BIOS issue

[Hqxriven]

Re: possible use full 4 Gb ga-h55m-s2hp

The packaging reads:

"Packaging produced in China
Motherboard produced in Brazil "

Lsdmeasap I appreciate the help and effort but do not want to work for you!

You've done a lot!

I will try this:

Re: possible use full 4 Gb ga-h55m-s2hp

What does it say printed on the PCB itself though?

That info isn't going to help, but you can try. He was just lucky to find one possible fix, that worked in his situation for missing/failed memory channels, this isn't what you are seeing or you would have a whole module worth of unavailable memory.

I'll run some tests on my end this weekend, but it's a different board and BIOS so mine may be ok, if not we'll know it's a H55 series BIOS issue and I'll send in a report again and see if they can look further into this.

This is her

http://br.giga-byte.com/FileList/Image/mb_productimage_ga-h55m-s2hp_big.jpg

I think the problem MAY be of any lot, since we have seen the same problem with another user and you even posted a picture of the recognition of complete 4Gb with H55 and the user is unable to do the same.

With that image was shown that the H55 can indeed have 4 Gb fully recognized.

The only thing I want to know is if this problem that is interfering with the detection of 4 GB can be corrected with a new bios or I have to face it as an unsolved problem and buying another gigabyte (honestly only trust the gigabyte, the only I sure have a good support)

Re: possible use full 4 Gb ga-h55m-s2hp

I wanted to know where it says it was made, on your actual boards PCB. It will be written in white silkscreen like the board revision and all the other writing on the PCB, you'll find it on the outer edge.

I just completed some testing for you, and I have found similar results. With a CPU with onboard GFX 4GB total available is not possible, and with a CPU without onboard GFX 4GB shows as installed/total, but there is still some 40MB or so reserved. It should show all memory for the 875K, and the 855K when onboard is disabled. My results are different than what you are having, as your issues are the same as what I get with 655K onboard disabled, either way it should show 4GB total when using a PCIE card so something is not right.

I have sent in a report tonight on this, with my testing results and a link to your issue and the other one I was previously helping with (possible use full 4gb h55m-ud2h)

I'll let you know once I hear back from them. I mentioned that I think they need to add a BIOS setting "Onboard VGA = Disabled", instead of just the setting available now "Disable If". I see Onboard GFX Voltage still present in 655K with a PCIE Card installed, so that leads me to believe it may not be totally disabled and that may be what's causing these issues. And I am really not sure why you are seeing these issues, since your CPU does not have a onboard GPU to begin with, you should see the same as what i see with 875K.

My testing results using H55N-USB3:

Click images to enlarge.

Min GFX Settings used - VGA Settings (Ctrl + F1) DVMT Set = 128MB / Onchip Frame Buffer Set = 32MB + 2MB Gtt

655K - Onboard GFX used




655K - 4890 Installed




875K - 4890 installed (4GB Showing in System Properties and taskmanager, but see notes)

Just now I saw the message, I open the machine and if possible get a camera to take some pictures to help!

Thank you for doing the test and sorry for the inconvenience and work that caused you and especially the time spent.

Thanks for your help, effort and attention!
