So, I recently built a new system w/ the following components:
Phenom II X4 955 @ 3.2Ghz
GA-890GPA-UD3H 890GX mobo
4GB (2GBx2) G.Skill ECO DDR3 1600 @ 8-8-8-24 1.40v (wasn't stable @ advertised 7-8-7-24 1.35v so I dialed back until stable)
ASUS DIRECTCU TOP 5850 1GB
Antec Earthwatts 750W PSU
hp dvd270 dvd-multi w/ Lightscribe
AFT 70in1 Multi-card Flash Reader
Antec Two Hundred Two case
Everything is running very nicely, but while reviewing my "detailed performance I came across a a few things that I'm not 100% about, and was hoping you guys might be able to help me sort it out.
Pasted directly from report:
Total available graphics memory 2807 MB
Dedicated graphics memory 1024 MB
Dedicated system memory 0 MB
Shared system memory 1783 MB
Now, what I don't understand is why there is 2807MB of available graphics memory? I went into the BIOS and looked at the IGX configuration, and here is where I am getting confused... it looks like the onboard 4200 is reserving 512MB of system memory, in addition to the 128MB of sideport memory, but that doesn't add up to 1783MB, nor is my System Memory showing up like any of it is reserved for the on-board graphics as it shows the full 4GB available.
Dedicated GPU - 1024MB
Sideport Mem. - 128 MB
UMA - 512MB
Between the dedicated 5850's 1024MB, the onboard 4200 claiming 512MB, and the 128MB of sideport, it ALMOST adds up to that "Shared System Memory" reading of 1783MB, but not quite. But even if, for whatever reason, that "Shared System memory" is the 3 of those together, where is it getting the other gig of memory from?
Really though, I just want to know what I should do about all of this? I didn't think my GPU supported Hybrid-Crossfire, and even if it does, from what I've read about it, I probably wouldn't want to use it anyway. So, should I disable the UMA? Disable the sideport + UMA? Or just leave it as it is now? I'd really rather not have that much (or any of my system memory for that matter) being gobbled up by an unnecessary feature, especially a redundant on-board VGA that is only going to gum up the works.
So if anyone could explain any of this, and give me some recommendations on how to proceed, I'd be very grateful. Thank you in advance
