XFX ti4200 Turbo

[Mitch007]

Just got this card (with 3.3ns BGA memory, gamers eddition) off ebay for $60, as a short term upgrade for my GeForce 3, and at this price seems like a great deal. Card hits 20,800 in new Aquamark bench, compared to 13,500 for the overclocked GF3, so I'm pretty impressed so far.
Any overclocking and cooling advice on this card would be appreciated. I'm a little worried that the cards stock hreatsinking is not really up to the job, and does the RAM on here really need heatsinking. It has heatspreader on both sides, but relies on the heights of the component being the same.

I installed a Zalman heatsink and a fan on my Ti4200 and have been very happy with it's performance. I've been able to run it at 300MHz Core and 600MHz Memory and I can get 23,XXX on Aquamark...and that is with a measly 1.1 GHz Celeron (o/c to 1.46)

I don't have any RamSinks on it currently. I've been pleasantly surprised by the performance of the memory as it is 4.0ns (500MHz) and its been running fine at 600MHz

I've now manage to overclock the card to 275/682 (that's 10%), and get snow flakes as the card heats from 30C idle to around 35C under heavy load, this is with thermistor/temp sense measuring air temp under the heatsink.

Is the speckling MEM or GPU related

Heatsink is shared (both sides) between GPU and MEM, (128mBit card), is this good or bad

So what next, how can I drive GPU/MEM higher.

Advice please!

I could be wrong here, but I understood that most 'artifacts' result from memory overheating while the core overheating will cause lockups and other crashes.

35C isn't hot at all for the core. Your memory is rated at just over 600MHz so 682 is a pretty good number. Can you reach in and feel the memory chips with your finger (if they are not covered up)? I remember when I first started overclocking my Ti4200, they got so hot I couldn't hold my finger on them for more than a second or so. Now that I have added a fan blowing on them they are just slightly warm to the touch.

I mounted a fan in the sidewall of my box that blows directly on the vid card (which has a Zalman Heatpipe cooler on it, no mem sinks), and it seems to keep things really cool. I'm comfortably at 20% over on both mem and core, with no signs of problems.

Just my two cents:

I find with my 9700 PRO that overclocking the core gets me snow, and memory gets me texture tearing.
