Hi guys,
I've been messing around with my GF3ti200 on and off for a few weeks, well it's probably only like a solid weeks worth of evenings at most and some things are still puzzling me.
i) The GPU overclocks GREAT!! however it redlined at 267 on cool days, 261 with a 28C ambient now, anyway, took off the stock HSF, scraped off the "bazooka Joe" thermal pad, lapped it, applied thermal compound and remounted it (spring loaded clips) and it dropped from 38 idle to 32-33, which seemed real nice. However, it didn't get me even one more Mhz overclock. In the hardware monitoring the alarm was set default at something like 60C, and it's not getting that hot, dropped it to 50, still no alarm before lockup. Wierd huh? Anyway, what volts can you push through these and what temp are they good for?
ii) Memory ... I should have 4ns memory on this, so I think I should be able to break 510 and possibly squeeze it up to 520, since 4ns chips should be selected from 3.9ns to 3.8ns, but I am only 100% stable at 471 at the moment and before it got warm here it was doing 487, though I can point a fan straight at the sinks and not get anything. However I could be having voltage issues with my PSU.
iii) When I get artifacting, it's totally not what I would expect from previous experience, it's like wierd. I expected missing textures, blocky shapes, white spots, that isn't really what I get, I get kind of brown "sectors" if you imagine a point in the middle of the screen, I get thin brown wedges in the top half of the screen usually, that flash up in various positions radiating from that point. What I think is really wierd though is that they seem not to be associated with textures or objects ..
So do any of these sound like they could be caused by drivers? I am running the supplied ones, which I think are a 23.xx release, I was thinking of trying the 28.90s.
The memory overclock seems to be reducing as my ambient gets higher, I am quitting as soon as I see artifacts, but cooling the memory better isn't helping. I am thinking that the heat is affecting the PSU and turning crappy voltages even crappier, because at lower ambients everything is all go again.
Oh BTW, does anybody know why Nature in 3Dmark is faster with hardware T&L off, running software T&L???? is it because there's only one light source??? I got 41.5 HW and 43.3 Software on one test.
thanks for any help,
