Riva tuner reserved system memory question!

[EchoTheDolphin]

I just recently (yesterday afternoon, yar!) got into actual application of all the videocard OC knowledge I've picked up here. I downloaded rivatuner and as you can see from my sig, got some pretty sweet clocks on my card, much higher than the goal I set. I then looked around and read about some of the more in-depth functions of riva and didn't find too much that I felt comfortable mucking around with or were of interest.

I did see a setting that caught my eye though. Now bear with me as I'm in a comp lab on campus so I don't recall the exact name of the setting. It was something along the lines of 'PCI system memory' that you could attatch a value in MB to. From what I understand it seems to set aside system memory for the card's own use, much like integrated graphics or lower-end cards.

My question is since I have 4gb of memory and when I'm playing games I generally don't have much in the background taking any of that memory up, would it be beneficial to give it a value of mabye 256/512/1024? Or since my card has a fairly significant amount (512) already for the resolution that I use (1440X900) does it not really matter?

I don't know that it matters much or will affect you in any way due to your rez, but it can't hurt, right? Set it to 512...can't see a reason to go higher than that.

As for your clocks...735 and 1811 are not actual attainable clocks. You need to use the Hardware Monitor to see your actual clocks. The slider values are not necessarily representative of your actual clocks.

If you're referring to the "Amount of system memory for PCI textures (MB) setting under Direct3D tweaks--> "Textures" tab, it doesn't have any impact on AGP graphics cards unless you're running in PCI mode.

So I'm assuming it won't have an effect on PCI-E cards either? As that's what my current card is.

Jason: I'm reporting based off of what hardware monitor was showing me, I'll have to get back home to double check later on this evening. However, I'm almost positive that's what I have, or at the very least my core clock is 735 and the shader core is linked to whatever respective shader clock would be.

Huh, Ill have to try that if it works for PCIE cards, could set aside a few megs since 1920x1200 puts some strain on the card right now.

[redduc900]

I guess I should have been more specific. This option is only for PCI display adapters (not including PCI-E adapters), or AGP display adapters running in PCI mode (e.g. with AGP caps disabled.)
