I've got an IS7-E board. My problem is the low vdimm (a max of 2.8v) which is not enough for me, as I have 2x 512MB KHX3000 dimms with BH-5 chips. As the mod looks too complicated to me (I don't think I have the right tools. Heck, I don't KNOW what are the right tools!) then I would like to get a new board which would be able to get the best out of my KHX3000s. I was thinking about IC7-MAX3 but then read it has some vdimm fluctuation problems at 3.0v and 3.1v (and maybe at 3.2v too?) which can be solved only using a mod. Then I considered the AI7 too, as it is cheaper and allows also up to 3.2v vdimm. I've also read on the boards that P4C800 is the best board to use with HyperX modules. The shop I bought the dimms at, akiba.fi, also tested the dimms using a volt modded P4C800. I haven't yet looked at the mod, but I've read it's easy; probably easier than the IS7-E one.

So what board should I get? I have my 2 old dimms that I will return to the shop for an 80% refund, so I need to spend the money on something anyhow.

Thanks,

Oren

A rather odd post, I must say. The problem with the ram isn't the voltage you're putting through it. I believe those are DDR370 unless I'm mistaken. On my system, I'm running a pair od Corsair DDR400 512mb sticks, and they run great at stock voltage. The fact that you're running them that high and still can't get them stable, something else must be the problem.

Where did you get that ram from, and do you think they could be refurbs? What about your power supply? You may want to fire up the motherboard probe utility (Never used that board, so I don't know what its called. Sorry) and take a close look at the voltages. If they fluctuate by a good distance (ex. more than .2 in either direction from the normal rating) then chances are, your PSU is the problem.

I've got the sticks from akiba.fi. I've been told it's quite a reliable site. Yes, these are DDR370. My vdimm is set to 2.8v but in the "PC Health" section of the BIOS it shows like 2.75v... I wonder if that's normal with IS7-E.

Odd.... Do you know of anyone who you trust enough to try the ram in their rig? There really aren't too many circumstances that require increasing the vdimm...

Here's a dumb question that I'm kinking myself for not asking earlier...(lol) What frequency are you running them at? If they're running 1:1, they're likely to need a little boost in the voltage department, but nothing to the amount that you're speaking of... It may be an issue with that particular mobo, but I really don't know enough to be sure. I'll post again when I have some more info about that mobo.

[Ludivous_Kain]

But, if you insit on getting a new mobo, the choice is a big no-brainer. By far the best board available right now (mainly because the competition is still having problems with their AGP lock when going above a certian FSB) is the Asus P4C800-E Deluxe. Its the one I had, and I am extremely satisfied. Never had a single problem with it. I'm running my P4 2.4C @ 3.81 (318FSB) with a vcore of 1.76. The only reason I don't go higher is because my proc isn't a real good overclocker. But anywho, In my opinion (and the opinion of many other people) this board is easily one of, if not simply the best one on the market right now. The only drawback it has is the price...

depends on what chipset the ram is im running 3.2volts on my ram, thrive at that 270fsb or ddr540 1:1 divider but to answer yr ?i wold personly go with the max 3 just me though the ai7 is really fussy about ram especialy if you have to go to a 5: divider just my 2 cents

I would have gone with the MAX3 if it didn't suffer from the vdimm fluctuation problems. I understood you can't really use the 2.9v, 3.0v and 3.1v settings, and probably neither the 3.2v.

I like my P4C800E-DELUXE.
I'm at 3.1 on stock air and I haven't even started playing with the voltage settings
