DDRII 800 Q

hi can DDRII 800 memory work in a board that only supports DDRII667/533 ?

I think so, amd you should be able to clock it to its proper 800Mhz speed.

What board you got in mind?

you can either try dropping the latencies (most DDR2-800 4-4-4-12 can hit DDR2-667 3-3-3-8) or overclocking the FSB to hit rated speeds.

i wanted to know if you could use ddr2 800 memory in a
ASRock 4CoreDual-VSTA board a long with a e6300

hmm. 333/266= 1.25 or 4:5 multi

so you'll need 320 FSB to hit DDR2-800 on the DDR2-667 setting. That'll Oc you E6300 to 2.25Ghz or thereabouts, which it should do easily.

I maxed out my DUAL-VSTA at 301 FSB, not sure how the 4Core does though, and watch for the memory voltages, as the DUAL-VSTA gave 2.0Vdimm on its "High" setting, and some DDR2-800 needs more than that.

thanks simonnance

i wasn't going to clock it really. just wanted to know if
it would run the ddr2 800 memory or down clock it to 667

downclock then. in the BIOS (if its similar to the DUAL-VSTA, which is likely) you'll get DDR2-667 and DDR2-533 options.

sweet thanks for the help simonnance m8

i may clock it up a bit. but the systems for my sister not me
