2. yes, change latency from 43 to 40 !

Thanks.

3. Most of my MSI bios mods were set for 3D of 485 or less because their owners found this speed best ?? Your choice of 500, was your choice ?? Before considering a set value for the bios, it is most important that you either find out what stable speed your card can do, or, research what other people found with their MSI5900XT cards ??

I did a 500MHz bios flash......that was too much for my card......so I changed back to 450MHz, although 485MHz is rock stable.

4. Your memory will survive 71C ! By the way, how are you measuring it with any accuracy, since there are no memory temp sensors ??

I'm using Vantec NEXUX NXP.101 CPU/HDD/Case Temp. Sensor with LCD.


Also, with your card, and if I were you, I would be thinking about fitting some sort of heatsinking to memory chips ? Some people have just fitted simple ram sinks and then placed a fan to blow air over them ??

Warranty will be voided if I attach ramsinks.....so I can't.

5. for set speeds, start at 300/450/820 and increase core in 10MHz steps till you reach 490 and test stability/performance ?

My card is stable at 485/850. Though I want to set it to 450MHz as a precaution.

It will be fine to just run Aquamark03 as it doesn't take long ! But to stress your card, it is necessary to set the driver manually to 8xAA and 8xAF for all testing !

I did check with 3DMark03. I'll check with AquaMark 3 & inform you.

Also, use coolbits for overclocking as it wont be necessary to reboot everytime you raise the core by 10MHz. Don't use rivatuner as overclocking with it prematurely triggers the throttling function, for which you will need to reboot everytime before making any performance tests !
I'm using Coolbits. Rivatuner is better to see pipeline configuration but coolbits is best for NVIDIA cards to overclock.

I'm wondering why memory is heated more than Core (C: 65C / M: 71C)???

So, you think 850MHz is safe for Hynix 2.5ns? I thought it is 50MHz more than official rating.

My card is rock stable at 485MHz, If i set my clock at 450/475MHz, do you think i need to set a lower throttling speed??

Thanks a lot, Jimmor.
