Ya it seems like it could a nice card. But If its not all you think it should be .
The Asus workstation 64 M/B is a nice board.

Turtle 1 ,you are confusing many things when AMD is in question.
First of all,mem. controler works at the speed of the CPU.No more and no less!
Second of all,AMD uses the whole numbers for the memory dividers for forming the frequency of the RAM.In other words,2.8 GHz FX62 chips when paired with DDR2-800 memory sets the clock for the memory to 400 MHz(divider 7).Nothing in this chip works at 2400Mhz like you said in some post of yours...
Other example,the 5000+(2.6GHz chip) when paired with DDR2-800 memory sets the memory in the following way :2600/400=6.5 which gets rounded to the next whole number which is 7.So the actual freq. of the memory is 2600/7=371 Mhz.Memory controler still works at the 2.6Ghz(full CPU freq.,and this is true for any part of the CPU like caches et al).And you need tho read the specs for DDR2 memory and about the base clock for instance.I can't correct you all the time and write the basic stuff...

I was tring to figure it the wayI would Intel . I Didn't understand. I see now that the memory is running at cpu freq. But I still dont get this part of it. memory freq is = to cpu freq 2600/400 What does the 400freq represent. and what does Quad pump memory effect in as far what numder is quad pumped and were did that number come from.
yeah, you definitely seem really lost when it comes to amd's memory stuff. here goes.. only cause i've explained it like 1396726 times already to other people :DQuote:

where the memory ratio is...
400mhz (ddr2-800) = 2/1 (2:1)
333mhz = 5/3
266mhz = 4/3
200mhz = 1/1
lowest x value is 5
for an example, if i set 340mhz htt, 9x cpu multi, 3x ht link multi, 400mhz memory ratio
cpu mhz = 340*9 = 3060mhz
ht link = 1020mhz
x = ceiling ( 9 / 2/1 ) = ceiling (4.5) = 5
memory speed is 3060mhz / 5 = 612mhz
understand now? :toast:
Thanks A ton . I got it finely. This is the part I was really struggling withQuote:

200mhz = 1/1 <- this is what had me really puzzled now that I see 400 is 2/1( quad pumped 200mhz 1:1 DDR2 800)
