You can fry your memory controller from too much Vdimm?! anyone got experience?

[Tim]

I just heard of this,....I'm have been running my VX @ 3.6v (It is slowly dying though, can't even do 210Mhz @ 3.6)

I guess there are no problems with my FX-55, it runs happy with Corsair XMS @ 222x13 2-2-3-11-1T no problems on Memtest....

can a faulty memory controller cause errors in Memtest btw?

So did anyone had experience with this? Should I be worried with running my VX at 3.5v?

wow

IMO it's just a myth... I've been running at voltages above 3.3v for a long time and nothing ever killed neiter my clawhammer or newcaslte. The cpu get's it's own voltage, teh RAM does too. nothing related to eachother. However you could melt some of your mosfets so keep them cool

that problem was only on the old nf3150 boards, particularly the Shuttle AN50R. I lost 1 board and 3 CPUs to vdimm back then.

problem is gone now though... crank it up

I suspect it's high LDT voltages killing the CPU's....this is the only thing that is a tad bit high on my board...and i have gone through 5 CPU's. But then again, this core i am using now is a newer one than the others I had...so maybe it was just a fault with the old cores.

I killed 4 3200's, and 1 3400 all in the span of 3 weeks back when the A64 754 just came out. it was cause of the motherboards, being susceptable to power spiking very easy.

one second your ram could be at 3 volts. a second later it could spike to 4 volts, silently killing your 64, and you'd never know why...
took a long time before anyone found out what was happening.

this issue was solved pretty well with the NF3 250 and NF4 chipsets.
it was also pretty common on the K8T800 chipset, like the Asus K8V, no idea if they ever fixed that... dont bother wasting my time with Via myself.

hey, this thread doesnt really belong in the xtremeoverclocking section wich is for xtreme overclocks only, i moved your thread to the amd section wich is for amd related topics.

please post in the acccurate section the next time, if you dont know what section to post in the please contact any of us mods and we will help you

and your question has been answered several times already, please use the forum search button next time and do some research

thx

Got it

These answers are just what I was looking for, many thanks from me

I find if I use too much voltage on the VX 4000 they will also error, I find even .05v too much can cause this.

Couple questions.

1.) how can it spike to 4v if it's off ur 3.3v line?

2.) 4v isn't too much why's it killing ur cpu, specially if it's just a spike. You can run 4v for awhile 'safely'. By awhile I don't mean weeks, but a couple hours.
