APU build not recognizing RAM

lilhasselhoffer · Jul 16, 2011, 06:24 AM

Hello,

I am looking for some assistance with a very recent build. The following components are in the build:
APU A8-3850
Gigabyte GA-A75-UDH4
600w rosewill supply
Win 7 Home Premium x64
8GB ram Gskill F3 (1333)

I have enabled ahci, updated the bios, reseated the ram, and made sure they were no memory limitations in msconfig. Despite this, I only see 6GB in windows. Memtest shows 8GB, CPU-z shows 8GB, and speedfan show 8GB ram but windows will not acknowledge its (the extra 2GB) existance.

What is the next step to get the extra two gigs recognized, or am I missing something?

Pull all the ram and test it in another system with memtest. Or test it one at a time in your system

Why enabled ahci?

The GPU's in APU's Use system ram, you've probably got the memory share set to high in the bios, and ram set to be graphics ram by the bios won't show up in task manager, as its hardware reserved

Solution = turn down the shared memory setting in bios to ~500MB, should give you access to more ram, and you won't have a problem on the graphics front

Run Resource Monitor, and in the "memory" tab, see if the missing memory amount is being shown under "Hardware Reserved" (gray). Tell us what you see there.

Memtest run, no problems. I ran at worse than stock to make sure everything was fine. I read on an AMD forum that enabling AHCI might help. I don't get the logic either...

The shared memory is set high (2.5 GB). It's accounted for, but is not what I am looking at.

Here's what I'm dealing with:

i think it says your mems compatible

http://download.gigabyte.eu/FileList...a-a75-ud4h.pdf

youd have to check the exact model nos

you have got them in 1 and 2 or 3 and 4 ie dual channel mode as in the same channel 2x double sided may have issues, sorry its obv but worth mentioning

Pestilence · Jul 16, 2011, 06:29 PM

You bought a Llano? Hmm.. Waiting for results

I checked the Mobo manual before construction. The memory is in the correct slots (1 and 2).

Beyond this memory issue, I'm getting some decent numbers. While not exactly a good indicator, the raw computations in WEI are rated at a 7.4. The thing that draws the system down are the graphics, but that is to be expected.

I've run a 1080p clip without any stuttering or stalling (though the cores all ran around 45% usage). As far as a workhorse, I can't complain. Gaming is another story. A quick run through of Crysis 2 was playable on the lowest settings, but just barely. I can't comment on the onboard video card expansion, because the person I'm building for wouldn't give the go ahead to get a separate card.

It's miles ahead of the Intel integrated graphics, but definitely suffers on raw computational capability. For a standard user, it isn't a bad compromise between price and performance. It isn't for a power user, but it's good for large segment of the market.

The only fix for me was to flash the BIOS to the most updated version which made the "auto" config in the BIOS for the RAM work.

de.das.dude · Jul 21, 2011, 08:36 AM

i think you need a new BIOS?

lilhasselhoffer · Jul 24, 2011, 02:56 PM

Sigh. I updated the bios before I updated the OS. Gigabyte tech support is moving slow enough to be win the race for slowest glacier on the planet.

Apparently this issue doesn't exist for everyone.

de.das.dude · Jul 24, 2011, 03:19 PM

then RMA it!

JrRacinFan · Jul 24, 2011, 04:23 PM

How much ram do you have allocated to the integrated graphics?

eidairaman1 · Jul 25, 2011, 06:25 AM

what version of windows are you running as in bits?
