Is anyone running the NF7/s v2 at 233MHz fsb without doing the vdd mod? I'm thinking about getting some pc3700 ram but I don't really feel like doing any more volt mods to my motherboards. I thought I read somewhere that 1.7v on the northbridge wasn't enough to get over 230? Please give me some feedback and experience from all you high fsb people.

I'm running exactly 233x11 with 2.8 vDimm no volt mods just a Zalman ZM47J on the northbridge. My VDD is at 1.6. Timings are in my sig.

233*11 at 1.8V, right now I'm at a 233*10 just to keep my cpu cooler. I use 1.6 vdd right now, but I've tried 1.7 to get past 235, but no luck. I really doubt that it's my ram holding me back, so I'm guessing that it's either my board or BIOS (essentially me board) that is holding it up. I've never gotten an exact answer on what vdd to choose for which fsb. I've heard that you can go to 1.8V safely on air, but beyond that...... 
I'd try the vdd mod, but I know that if I ever did that mod, I'd do the vdimm and vtt mod as well, and I like my board too much to chance killing it.

It seems like your ram is holding you back. Well at least at only 2.9 it is if you did a Vdimm mod and gave the ram 3.3 volts it'll do 250 easy.

You think that my ram is holding me back? It's only overclocked by 17 Mhz??? I was under the belief that this ram could reach 250 with these timings. I'd try the DDR Booster, but I'd like to make sure that my ram actually likes high vdimm like BH-5.

From what I've seen it like high voltages. You might want to try PC3700 timings.
For 250FSB with no mods get some hynix BT-D43 using timings like 3,4,4,10 and a CPC off BIOS.

Yeah, I love Hynix. I had the pc2700 for a while that did235 at 3-4-4-11. I loved that ram.

Sure, you use Trats D24. Also you use the chipset voltage of 1.4. Other than that its mostly luck

ahhhhh... one of the heavy hitters.... good.... you didn't have to do anything special to the board to get to 250?
I've used trats d24 and I'm using merlins right now.... my ram won't go beyond 227 (Simpletech pc3500 won't go beyond that) so I know i need some new ram.... I just wasn't sure if I had to do any volt modding to get up into the thin air.

Its possible you have Hynix, change your timings to 3-4-4-11

did that..... no go with various timings and vdimm.... my understanding is that the simpletech ram is just not that great for overclocking.... people generally get 8-10MHz over stock..... I bought it cause I got a gig for $160..... 
now I'm thinking about going to the next level and the pqi pc3700 ram looks pretty inviting.
Thanks for the info guys...... I'm guessing one of my nf7 boards will get me to the 240-250 area and if I really have to I'll do a volt mod or two..... just hoping I don't have to.

i was able to get 240 boot into windows but not prime stable. right now, i m running @ 9.5x235 primed stable without any mods. voltage are vcore @ 1.825, vdimm @ 2.9, vdd @ 1.7.

sweet..... i really need some better ram.... based on what folks have said earlier today I've been inspired to get back at tweaking trying to do some more with this simpletech ram..... memtesting right now at 227

Give those babies 2.9 volts and see what they can really do.

Sounds like CH5. I wonder if it will do 2-2-3-11. Try that
