pc 133 ram with asus a7v

[Guest]

I just built my own computer and I used pc 133 ram that I bought a year ago. Every time I try to change the bus speed to 133 on the ram, Windows will crash with some funky error. I have to change it back to pc100. Is there much performace increase in pc 133 over 100? Any reason why I would get crashes on the 133? Thanks for you help. I am running asus a7v/1000 ghz thunderbird.

I'm not sure what the perfomance gain is, I think it's about 3-4% ? But it sounds like the memory you've got might not be PC133 compliant ? If you know someone else with some working PC133 memory try install that, at least that will tell you if it's your memory or a problem with the mobo ?

You should get what you paid for, so make sure you have PC133 ram and not get cheated... check for those serial numbers and from the manufacturer's web site if possible.

Yeah. check your mobo first with known PC133 RAM

Can you adjust CAS latency of ram in BIOS?

Early PC133 DIMMs were often of dubious quality, and even now the memory has to be better than the cheapest to put up with the timing translation from the 200MHz DDR EV6 bus to 133MHz that the chipset performs. You will notice the difference compared to PC100 in bandwidth-intensive apps (like games). Your best bet is to buy a stick of non-generic memory - it's as cheap as it ever gets now.

Insight UK are selling Cube PC133 128Mb SDRAM's for £57+vat at the moment.

Make sure the the CAS is set to 3 and not 2. Also make sure that the Frequency is set to 8ns (125mhz) and not 7ns (143mhz). You can ensure this by setting the frequency setting to "SPD" If your memory is a year old then it is most likely not able to handle 7ns or CAS 2.

The A7V and other newer boards are very picky about running PC-133. Your absolute best bet is either to buy new CAS-2 PC-133 (preferably Corsair or Mushkin) that is aproved to run with thunderbirds. Watch out now some companies will say that the motherboard supports it but they mean something else. That's why its important to get good RAM from companies that are proven good. IE the two I have mentioned and Micron as well. Or you could just run it at 100MHz and stop hissy fitting over only 10% of speed.

This new forum sucks

when changing from 100 to 133 make sure you change your latence to cl3 and not cl2 older pc-133 ram is not cl2 compliant
