I see allot of people are running a 220 FSB. What type and speed of ram are people running ? I have seen adds for ram that run at 250 MHTZ FSB anyone using this and have you achieved the 250MHTZ speed? The reason I am asking is I currently have PC2700 ram and am holding out on purchasing faster ram.

ram.

OCZ PC3500 EL @ 2.0-3-3-7 @ 220 MHz FSB on a NF7-S (runs at 230 MHz at 2.5-3-3-7).

I'm running a P4 2.4g at 275x12=3.3 ghz. The ram is at 5:4, for 220 mhz at 2,3,2,6. Buffalo Technology PC3700 with Winbond BH5 modules, $57 for a 256-meg stick or $99 for a 512-meg stick at www.newegg.com

Hi,

not sure if you mean for an AMD platform, or an INTEL platform?. My nForce-2 is running 220MHz-FSB and it works well. My memory is rated for 217MHz so that's getting a tiny overclock. I have read of people running 225-230MHz-FSB on their nForce2's but I think they had performed so small mods to accomplish this (SB HSF?).

The INTEL platform is able to make better use of the Dual-DDR tech when running FSB speeds of 250-300MHz with memory at 1:1. Although the majority of people run with a 1:1 memory ratio I have read of certain cases where running your memory *async* (i.e:5:4) with tight timings can produce better results than running a 1:1 ratio with high FSB and lousy/slow memory timings. . .

The truth is out there!

that memory working out for you? i've seen countless posts at the sharkyextreme forum of people blasting OCZ for instability at advertised speeds/timing/DOA chips/RMA probs etc, my moms b/f has 2 sticks of 512 OCZ ddr and he gets it over 200mhz fsb...maybe they are starting to go downhill?

I got this memory back in April and I did have errors in memtest86 with the first two modules. I exchanged them right away and got two others that have been rock stable since then running at the above mentioned speeds and timings. They are spec'ed to run at 433 (216) MHz @ 2.0-3-3-7 and they run at 220 (440) MHz at those timings, again with no problems.
 
I'm running at 244 FSB but using an FSB:DDR ratio of 5:4 (80%) so my DDR speed is 388 using Corsair XMS3500 at 2, 5, 2, 2 on an IC7-G

How does it do on an amd machine nf2 for instance, have found ram that screams on intel dosent always do the same on amd and actually is very rare to work like this on both systems.

Good point. The requirements are a little different, depending on your goal and platform.

For example, if you want the ultimate performance form an Intel box where the multipliers are locked, you want high-dollar PC4000 that will run at an fsb of 250+. To get there, you usually have to run loose timings, most often CAS 3.

But paying that much for memory in an AMD system is a waste, IMHO, because most Nvidia-chipset boards aren't stable at such high fsb speeds and you can get better results by changing the multi and keeping the timings tight.

What you need is memory that will run CAS 2 or 2.5 at 210-220 fsb, in other words the best PC3200 or decent PC3500-3700.

In this case, the Buffalo Tech still fits the bill, and I've seen good results posted on both Intel and AMD systems. I don't sell the stuff, so I don't care what you buy, but I do think it's a good deal.

There are lots of options at lots of price levels. Check the reviews at www.amdboard.com to see how various sticks compare, and read the forums at http://forum.abit-usa.com/ to see what others are using on an NF7-S.
