I'm planning to buy a DFI LANPARTY UT nF4 Ultra-D and use it to overclock an opteron 165 from 1.8 ghz to hopefully 2.7 ghz (I've seen other people claim to do it with the DFI).

If I want to set the FSB at 300mhz, doesn't that mean that the ram needs to be able to run at 600 mhz? And doesn't that mean I have to buy DDR600 ram? Or am I missing the point of overclocking ram? Can I use pc3200 (DDR400) ram to run the FSB at 300mhz, and if so, which brands/models are well known to accomplish this? Also, If money were no consideration, would it be better, or cheaper to use a cheap brand of DDR600 ram rather than an expensive brand of DDR400 even if the DDR400 would work?

I would really appreciate a response from DFI users; I know the opteron 165 is a popular overclocker. Thank you!

you need to buy a very good brand of ram to get that preformence. I suggest Corsiar XMS PC3200 or OCZ Platnium PC3200

oh and AMD only supports up to PC3200 (DDR400) RAM as of this socket model their next socket M2 should support DDR2 (and DDR3???)

Thank you for the quick reply! I think I'm misunderstanding somthing. Are you saying that I cannot use anything over PC3200 ram? That doesn't seem right since DFI's site lists recommended ram at higher DDR rates: http://http://www.dfi.com.tw/Product/xx_product_memory_us.jsp?PAGE_TYPE=US&INDEX_TYPE=M B&CATEGORY_TYPE=LP&SITE=US&PRODUCT_ID=3471

AMD doesn't support any thing over PC3200 RAM they don't have the 240pin DDR2 slots they only have 184pin DDR slots. In probably 3-6 month the next socket type should be out and then they might then. They can overclock to DDR2 speeds and beyond though.

Ok, I'm sorry, I must be dense, but are you saying that if I buy DDR500 or DDR600 ram, It won't work in the DFI motherboard? If so, then why would DFI recommend them?

Ok, lemme give this a shot...

Kyndig, you can use DDR500/600 in it. I think what bob meant was that most mobo companies list DDR400 as the highest DDR their mobo's can take. However if you are overclocking then it all depends on how good the board can handle anything over ddr400. Getting ddr400 to run at ddr600 sounds a bit difficult to say the least but you can still get your FSB of 300 by using a divider and have the memory run a bit slower say at ddr500 (which you would likely be able to get by oc'ing some good DDR400)

ok was that any good for my 1st time ??

Ok, I understand. But I thought that the ram speed should always match the FSB speed. I guess the ppl who got the opteron 165 to clock at 2.7, didn't have the ram running at 600 mhz.

So, if I buy DDR500 ram, I might be able to OC it to DDR600, or I could just buy DDR600 ram to guarantee that I can run the FSB and memory both at 300mhz. Is that correct?
