Can someone explain to me if there is any difference in running pc3500 at 333 compare to pc2700 at 333? I know people overclock their memory but do you really have to do it inorder to get maximuam benefit from it? would i get any benefit over pc2700 if i ran pc3500 at 333 speeds?

I've read + heard alot of reports about people having problems using Corsair's Xms series of memory in combination with a Sis chipset motherboard. I'm thinking about getting the Corsair ddr3200 or Corsair dd3500 for the Gigabyte GA-8SG667. Now many of these reports/problems seem to come from overclockers. Does anyone know if there are any issues with the corsair xms series of ram if you're not overclocking?

One more thing if i decided to run cosair pc3500 at the normal 333 would i still get any benefit of having pc3500 as compared to using pc2700. (I like to have the 3.5 gig of bandwidth/transfer per sec) I'm not going to over clock the system. The board supports (according to recommend list) ddr400 = 333mhz.


Thanks

Unless you are overlocking there is no point going for pc3500
unless you are into overclocking....
A 3500 will take the beatings better than a 2700 if overclocked
 
Sorry for my ignorance but i'm a former Rdram user and this ddr thing is driving me bonkers. I keep thinking the higher the pcxxxx the better it will be.

Okay, Now what happens if i don't overclock the processor but overclock the memory up to 4xx mhz using pc3200/pc3500? Would i get any benefit form it now?

Okay, This is what i've learn so far, so here goes. (please correct me if i am wrong)

pc3200/pc3500 is really not benefical until you can clock the dram mhz up. If you don't overclock the dram there's pretty much no difference in using pc3200/pc3500 vs pc2700 on an intel machine. You gain nothing extra. Since no motherboards offically support pc3200 or pc3500 the only way to get benefit from a pc3200/pc3500 on a p4 machine is to overclock the dram. Which in a nutshell means there is really no difference between pcxxxx vs pcxxxx other than the fact that a higher pcxxxx will survive running at a higher dram clock speed with no problems and that unless you overclock it or a board comes out that supports a speific clock speed for a specific pcxxxx there really isn't any point in getting higher pcxxxx ram. Because its the dram clock speed that makes the memory.

Oh one more thing, I've heard and read that many people are having problems running Cosair xms seriers of ddr ram in conjuntion with a sis chipset mother board. Most of these reports are from people who tend to overclock so i'm wondering if this memory will run stable with a sis chipset board if i am not overclocking the processor but just the memory? or if i don't overclock anything at all

thanks again

Sorry for the long post but if it's to long to answer does anyone know of a place where i can find a article about ddr in depth?

Thanks
 
well, the new PE chipset and SIS has supported PC3200 operation for a while.

PE is unofficial, but...most mobo manufacturers advertise them as DDR400 operation via overclocking so there you go. Also VIA has a P4 chipset that works DDR400, not the best one, but an inexpensive alternative.
