Ram and Gpu overclock questions.

[Dogz]

Hello everyone,
I am thinking of oc'ing my ram and GPU from my Bios I have already done the CPU and it shows where to set the ram so what would be safest to set it at it already runs 800. The BIOS does not show a way to OC my GPU does this mean I have to download a program to do it for me?

You could probably overclock you RAM to around 1066MHz if you relax the RAM timings and up the voltage a bit, or you could set the RAM to be on a 1:1 CPU:RAM ratio with your CPU.

Use something like EVGA Precision or MSI Afterburner to overclock your graphic card.

Be careful when overclocking RAM. They're one of the easiest components to mess up by a bad OC. Heat tends to kill them quickly. If you can't hold your finger on the sticks when they're under load for more than a few seconds, it might be a good idea to get one of those RAM cooler fans, or back off the voltage.

Indeed RAM is the easiest thing to kill overclocking.

So it all depends what RAM you are running (speed its rated at) and what FSB you are running at.


This is why many overclockers go with DDR2 1006 or higher RAM for an Intel system they will be overclocking.

If you have DDR2 800, I wouldnt push it to far beyond that.

For 1066 RAM, you have much more room to play with. You can run at 1:1 or even a bit more.

Such as a strap of 333/800 for example.

You may not alway run at its rated speed, but once you reach the desired CPU OC, you can then tighten timings..


General rule of thumb, try to OC without actually OCing the RAM. In other words, if your going to OC, get RAM rated at a faster speed than you really need.
For most socket 775 Intel systems, 1066 is about right.

But even with DDR2 800 you can get respectable OCs at a 1:1
