i think all of us here already knew that value ram wouldn't be able to hit 270HTT, even with those dividers

Why not? The dividers should have the ram running about 178 which is below its rated 200 so I don't see what the problem is. Can you explain?

no, i wouldn't really have an idea why, maybe it isn't fully compatible with your mobo, but as i said, i wouldn't have a clue

you're not making sense?

if you are using dividers you let the ram run slower then your HTT, and the only advantage this can have, is that you can clock your CPU higher if you don't have an Athlon FX, which means you'll be stuck with a maximum multiplier.

there is no other advantage of increasing your HTT and using dividers in my humble opinion

JMKE,
That's what I thought. The only two other possibilities that occur to me are:

The PQI Turbo ram I could hit 270 with was single sided whereas the value ram is double sided. Since there is no Bank Interleave control in the bios of my VNF4, I think this might be affecting my OC potential. I might need to get some single sided 512 MB modules if this is the problem but I'm not sure if those are made.

The only other thing that occurs to me is that maybe the PCB is causing problems but I am totally ignorant of how the PCB affects ram performance. Any suggestions?

lol, indeed you are right jmke, duno what i was thinking when i wrote that it was kinda late so i prolly wasn't thinking very clear anyhow, what i prolly meant was what i wrote, without the part of the dividers, and permodot, i don't think they make singlesided modules of 512, they do with 256 though if i'm not mistaken

That's what I think Gibson which could be a problem then if the bank interleave is what is causing the issue.

i guess switching to 2*256 isn't really a good option eh, 512 is not enough these days i think, btw, are you sure there aren't any bank interleave options? (sometimes motherboard makers hide certain advanced options to keep things tidy)

I've looked, believe me. Only other option is to get a different mobo but I'm not sure which one. This Chaintech VNF4 was pretty inexpensive, $85, so trying to find something that OCs well at a low price will be a little tricky. Any recommendations for an NF4 Ultra mobo?

the DFI nf4 ultra should be good for oc'ing, it runs at +-130 atm, it's a bit more, but i bet you get a lot more extra's too
personally i'm planning to buy a DFI nf4 SLI-DR in july
