Turning RAM up to 133?

[EliC]

I have a Tyan Trinity 400 MB that supports PC133 and 128MB PC133 SDRAM. I am using a cleron so the current bus setting is only 66. Can I go ahead and crank the RAM up to 133? Is there any danger in this? Any benefit?

Note: I am not an overclocker and do not wish to take the associated risk. I want to know if this is completely safe

Andre - The Tyan Trinity 400 uses the Via 133A chipset, which can unsync SDRAM. I would put the RAM speed to 100, and leave the FSB at 66 if I were you EliC. 100 is a nice safe number that most RAM can handle.

Yeah, I wasnt going to touch the FSB, just the RAM clock. HOwever Andre, you seem to indicate that there may be some danger to this. Does anyone know? Is there a performance gain with the FSB still at 66?

This will increase memory bandwidth a good deal (something that would be very favorable on a VIA board).

I think Andre was stating that just about no celeron will hit 133FSB (doubling its clock speed), which is entirely true. If your RAM chips have -10 or less written on them, I would not hesitate to turn it up to 100Mhz DRAM clock.

[EliC]

What is the -10 for?

You can´t o/c your Celeron to 133MHz FSB. Thats cuz´ as you said yourself, your CPU is running on 66MHz FSB. No matter what Celeron you have you will never be able to use the 133MHz FSB setting. Well, there are always a few extremes but since you don´t wan´t to o/c then...
Sorry, but ya have to get a P!!! or CuMine to do that.

10 nanoseconds. It was tested to run at 1000/x Mhz, where x is the ns rating of the RAM, sometimes even higher, but never lower.
10ns = 100Mhz
8ns = 125Mhz
7ns = 142Mhz
6ns = 166Mhz, and so forth.

Are you saying their is a lot of PC100 RAM already out there that is PC133 compliant?
