How well can you overclock a 6600GT?

[leegroves86]

I recently purchased an Asus 6600GT... it has a stock speed of 500 MHZ for the Core and 1.0GHZ for Memory. Using coolbits with Stock cooling I was only able to overclock it to 555 and 1.10 GHZ for Memory. I can't get it to go an inch more.... its says the test failed running at these speeds. The card is NOT passively cooled and my case has 2 intake fans and 2 exhuast fans.... not too bad.

Did I get a crappy overclocker or what? is this normail?

Check here
This page specifically
525~590MHz on the core
1120~1220MHz on the memory.

533 core 1.1GHz stock cooling using Cool Bits.

Leadtek @ 546 core, 1100 memory. That's pretty much the limit; I might've gotten the core to 551 or something, but I've never gotten the memory any higher.

Mine's in my sig. I had to post to see what it is (not at my computer), Maybe I'll try 1100 MHz on the memory.

Just fair warning, if the memory chips are bare, overclocking can damage them over time (the leadtek 6600GT does not have ANY cooling on the memory).

I slow roasted a Leadtek 6600GT a couple months ago that way. It ran perfectly fine until one day i did a lot of gaming and about 7 or 8 hours into the screen went black, powered down and powered back up, artifacts everywhere in bios.

Was that using Coolbits?

Yeah, the problem i ran into was that it was perfectly stable up until the crash. Talking to my leadtek rep, (who is actually a knowledgable salesperson <3 leadtek) he said that because there is no thermal throttling, or even a thermal diode to check temps on the memory, it may run fine right up until the point of damage from heat, causing exactly what happened to me.

A cheap aftermarket kit with some el-cheapo ramsinks and thermal tape would probably make you safe, and they go for under $20 nowadays if you wanna keep your extra 10% memory OC.

Not telling you what to do at all, just hate to have someone go through the same $200 mistake i did
