How Easy is 217MHz On NF7-S 2.0?

OC-Master · Apr 24, 2003

How easy is it getting 434MHz FSB outa the NF7-S Rev 2.0 with two sticks of Corsair PC3200 LL memory? A friend of mine is building his rig and his motherboard is on the way.

Are they single sided or double sided sticks of ram? If theyre double sided and you wanna run at 217 in dual channel, its EXTREMELY hard. Single sided in dual channel is a challenge, but it may be possible with extreme vdd and some added vdimm. Make sure youve got coolers on both the north and south bridges. The NF7-S only has one on the north stock, and without one on the south at those speeds, good luck

Overall nothing is certain, so nobody can tell you whether itll run at that speed or not. If its single sided ram youve got a good chance with some patience. OCing always depends on luck.

wouldn't that depends on the cpu too?? Unless he use very low multi, altho i dont see what you get by using higher fsb with lower multi, compare to the other way around...more memory bandwidth?? Would that increase the overall performance by a significant margin?

memory bandwidth is a lot more important to overall performance then sheer clockspeed. everything responds faster when your running a high FSB and you get quite a few more FPS in games then just a multiplier overclock at the same speed.

i have the rev2 and Corsair TWINX PC3200LL 512MB, i'm running at 200Mhz right now (400DDR), i had to raise the voltage on the ram to 2.7volts though because the screen was full of garbled text at default voltage (2.6volts). i haven't tried any higher but i really think i can hit atleast 210Mhz

btw, my ram timings are at 6/2/2/2 right now.

how high kan tha pc3200 xms c2 get? i get 203fsb with it....just wondering

IGUANAS · Apr 25, 2003

i can get 217 7-3-3-2 in dual channel with a pair of crappy ocz pc-3500 basic series, and default chipset voltage

v8vega350 · Apr 26, 2003

i can get 217 out of crucial 2700 @ 2.8 vdimm single sided 256 meg sticks with cl 2.5

USAPGAPRO · Apr 26, 2003

Im hoping I can at least get that on mine with XMS3500.

v8vega350 · Apr 26, 2003

there is what you want it might be easier to do with faster ram but for these 2 stick it was 80 dollers plus i only run a fsb or 203 ususualyhere

timmyqwest · Apr 27, 2003

Wow, i must have some luck, i'm currently at 10x410 and trying to work my way up, i wana see if i can hit 420 then we'll see if we can up the X'er...

DiaperGravy · Apr 27, 2003

Umm well... I didn't go with the good old Corsair this time, but I'm currently running my Twinmos/winbon PC3200 @ 2.9v For a FSB of 225*11 on my 2100 T-B 301... So I guess I'm satisfied, could be worse

i bet if ur ratio was 3:3 you guyz couldn't run high fsb's with pc2700 ram or lower.......

v8vega350 · Apr 27, 2003

i run 3/3 4/4 5/5 6/6 it dont matter mine is 1/1 in sync if you click the here word on my last post it will show a speed in sanda of over 3300 MB per sec kinda high for ram thats only supposed to do 2700 MB

IGUANAS · Apr 30, 2003

now i had my pair of ocz 3500 basic at 220mhz 7-3-3-2
GREAT!!!

MetalStorm · Apr 30, 2003

How can you tell when the ram needs more voltage??? Im currently stable at 200x12 but I could get to 220x10 I think, but it was pretty unstable...is that because of the ram voltage? - If it is then what is the maximum safe voltage for PC3500 ram?

v8vega350 · Apr 30, 2003

well you could turn down you multiplier and see if it is stable or not eliminating your cpu if it is unstable raise it if it is still unstable try the chipset to

??what are you betting this on? your pc2700 ram?

i dont think he'll have a problem at all running that speed

(not to say it isnt luck, but i dont know how much he needs in this case)

Right now I can't get my XMS PC3200 to run at 6-2-2. I ran Memtest and it fails after 5 minutes. If I put it to 7-3-3, everything is fine, but I think it's this new stick of RAM I have. I'm about to test it by itself in Memtest at 418MHz at 6-2-2 CAS2. I already called in the RMA because it was acting flaky the first time I put it in, but that was also on my KD7, but this time I will know for sure.

timmyqwest · May 1, 2003

Either my good luck or your bad luck, i got that same ram running @ 220mhz (till i f'ed all that up

)

SlowBurn · May 1, 2003

I just tried to run both my sticks of RAM individually at 418MHz 6-2-2 CAS2 and they both failed. One a lot worse than the other. I'm talking I had over 1200 errors before it was done with the first pass (all selected tests). I put them both back to 7-3-3 CAS2 and everything is fine.
