View Full Version : Vdimm on a A64 rig

Hey guys,
I had this little talk with Sen (Sentential) about moving to an A64 rig.
and using my ram I need really high volts to get a decent speed.
anyhow, he told me that vmoding your vmem can cause damage by killing the CPU's onboard memory controller.

Have you ever heard about that?
The motherboard to be modded is a MSI K8N Neo2 Platinum if that matters.

Thanks,
Suma.

I have heard about that problem, but not recently. The newer cpus might not be as prone to it, but I would be careful.

Define careful. :)

No more than 4 vdimm :burn:, but I would up voltage slowly, and look at XS for other people that have done this, because there are some crazy voltages over there.

nah 4v is too much, I need around 3.3v-3.6v
I'll look it up on XS too thanks.

The problem was on the old AN50R board's, i wouldnt go above 3.1v but thats just me. I can tell you tho 3.6v is to much, 3.3v is prob the max you should go to for 24/7 usage.

BH-5/6 is secure to use with up to 3.6v
Winbond says that.
I use 3.4v for 24/7 usage.

Do you say that this problem was only with the AN50R boards and I have nothing to worry about?

Thx.

Suma your fine vmodding that board, but I would only do the VCORE if you need it and get the Ram juice via booster. One thing I did catch over @ Xtreme was guys were saying that BH-5 in dual channel really needed some volts up it's ass to match S754 speeds.

I ran 3.6v on my Epox board with my Samsung pc3200 TCCC ram and got 260fsb 1:1.

It doesnt matter how far the ram maker says the ram can go the Integrated memory controller also takes the punch fro ma high memory voltage, and yes the early S754 board the AN50R one had the problems where a high VDIMM killed the cpu's. I have yet to hear an A64 dying from high vdimm now, you still should be very cautious

It wasn't high voltage that killed the early chips, it was voltage spikes from adjusting a vmodded/railmodded rig's vdimm via the BIOS. And it wasn't only the Shuttle that had this problem, guys lost chips on Gigabyte and other boards also.

So am I fine with a vdimm of 3.3v~ ?
and does this board has VTT tracking?

Thanks,
Suma.

From what iheard it was just those board, but i guess im wrong, my board's vdimm is modded and i keep the thing adjusted to where if i set 2.7v in the bios i get 3.02v, and if i set in the bios to 2.8v i get 3.1v and so on, i use the bios to adjust the vdimm instead of going to the Pot and adjusting it everytime i want to increase of decrees the vltage to 3v to 3.1 or 2.7v ect. My cpu hasnt died from doing this..

I see. so I guess I'm fine then.
Thanks.
