Board says it support 2.5v DIMMS but also PC3200

This is the Tyan Thunder K8S Pro. Should I go with PC2700 to be safe?

found this corsair ram pair

2x512 pc3200(CL2.5) @ 2.5V

Its up to you really....your not going to hurt anything by undervolting the ram, and if its good PC3200, you could probably run it at 2.5v just fine. you SHOULD be able to up the voltage in the BIOS to 2.6v just to be safe. if you can't up the voltage, then you should be able to lower the frequency a bit, but i don't really know anything about the BIOS's on Tyan boards. Getting PC3200 and raising the voltage will leave you with a faster system overall, but in the event you can't raise the voltage, you'd be wasting time and money getting pc3200...sticky situation...


edit: ah, blackdog got in ahead of me, but there you go, go with the pc3200.

Whoa....do I want to be putting Value Select on a server? I was planning to go with XMS.

It also has to be registered memory.

not all pc3200 ram is 2.6v.

i would go with crucial for a brand. just a suggestion.

ah sorry, didn't know about the other requirements.

2.5V is the JDEC spec for PC1600-PC3200 memory some modules require higher voltage to operate correctly, so just make sure you get memory that will work @ PC3200 speeds @ 2.5V if your board doesn't support higher voltages.

Hi, Don't quibble over .1 of a volt. For all practical purposes they are one and the same. Jim

LOL.
Be quiet?

See if the motherboard will support any overvolting (or correct voltages)
It might say on the manufacturers website. Or see if you can find a review, and check what RAM was used?

I was pretty sure that although the JEDEC standard for DDR during the PC2100/2700 days was 2.5v, because of chip yields and timing issues at the time that PC3200 was being introduced to the market, that they made the standard for PC3200 memory 2.6v, or at least allowed modules requiring 2.6v to be considered standards-compliant. It wouldn't surprise me if the silicon these days being much better, didn't allow them to drop voltage back down to 2.5v for PC3200. Nearly all of the valueram-eque PC3200 that I've used, clearly states 2.6v on the box though, and in the interests of maximum stability, I've always set it to that.
