Intel P4 heatsink on a Nvidia 7900GS video card - Page 2

post #11 of 21
Fluctuation under load is normal. Once you do the RAM vmod, be carefull, because the RAM voltage seems to climb a little too.

ie. i set mine for 2.18v idle and usually see it around 2.20 or 2.21v under heavy load...nothing to worry about though.

Yeah, your right... under load it climbed all the way up to 1.62v.... actualy it seems the longer I leave the system on, the higher it gets.. hmmmm lol

We’ll it looks like I hit a bottle neck with my over clocking, after I increased the core voltage from 1.5v to 1.55, I went from 685Mhz core to 710Mhz (fully stable)
I ran 3dMark2006 and scored 5264(at 1.55v), previously I scored 5221 (at 1.50v).

Is my bottle neck do the memory not being Volt modded or is it my CPU? I’ve read that once your close to 700Mhz or you go over 700Mhz you have to mod the memory to take full advantage.

I don’t have any memory heat sinks on my video card, but I touched the memory chips with my finger during one of the most graphical intensive part of 3dMark2006 and they were barely warm to the touch.

I have a 12cm fan blowing air directly on them…. do you guys think I should try the memory volt mod and see where it takes me?

We'll... I went ahead with the memory volt mod any way’s, I couldn't resist. The RAM chips we not even warm when gaming or bench marking 3dmark2006. With a huge intel P4 heat sink and a 12cm fan right bellow I don't think I'll have any problems.

My old ATI x800GTO video card RAM chips used to get boiling hot and I never had any issues.

Is there an easy way of keeping an eye on the RAM chip temperature? would a regular thermometer do the job? or is there an on board sensor on these NVIDIA 7900GS video card?

I wasn't to impressed with the memory volt mod, I went up from about 840Mhz to 920Mhz, but my 3dmark2006 scores went up from 5200 to about 5350. (These numbers are off the top of my head since I'm at work a the moment)

actually, that's quite a jump for the mem volt mod, apparently volt modding my x1600's memory barely nets 10MHz, if anything. I think in alot of video cards, the memory is already very close to it's limit, voltage or not.

this is making me want the AGP version of the 7900GS...just to mess around with. Sounds like it would be a beast watercooled!
