So many A64 deaths

Errr bit OT, an50r has working pci/agp-lock ?

yes with newest bios

modded versions out ?

I ran 3.3vdimm on my 3200+ for a month or so and no ill effects. I had a K8Npro with the +3.3v to cap mod on it. Then I picked up a K8NSpro and decided I wanted adjustable vdimm so did the normal VR to IC to ground. I need to run +3.6v on my 3.3rail just to get 3.2vdimm and again no ill effects.

You don't need a modded version as far as I know. The official one should do the job great. Perhabs this could be possible on other boards too? Let's see :)

@sai: where do you live in frankfurt? Big City ^^

not exactly in Frankfurt, about 15km away from frankfurt

does any of the two of you maybe know a girl named anne? shes around 22 and was in venezuela with me for 1 year with an organization called AFS. :D

lived in/around frankfurt , i know its a big city, hehe but hey its worth a shot ^^

I had for 3 monthes a Shuttle AN50R and 24/7 use with 3.3v Vddr was doing fine.
I also think 3.3v is quite the highest safest voltages. higher then that is for die-hard 1:1 OC and benches :D

Sometimes i tried 3.5-3.6v but somehow my pc keep shutting down and stay 3-5min down :confused:

Advise:

If you feel that your CPU is not OC'en good as before. Example: BSODS, bizar erros etc. ... Run STOCK speeds/voltages for a while.

so whats the deal with socket 939 boards? Do they suffer from these vdimm related deaths? DFI's 939 board goes upto 3.6v and so i just wanna know the latest news on the A64's deaths. Should have follows this more closely when it was happening but i was busy :(

Cheers.

where did you see 3.6vdimm for the dfi neologan. that is fantastic if true

not sure its true but it's all i heard about the 939 boards so far.

Hello
I found this forum today, 7-26-04. Very interesting.
I HAD a Chaintech ZNF3-150 with a 3000+
BOTH died 2 weeks ago. They were only 5 months old.
And I DID NOT overclock or overvolt.
I got approved RMA's on both.
I bought a Gigabyte K8NS Pro 'cause Chaintech said it could be 10 days plus shipping time.

Thanks for the heads up.

i wonder if the VTT(bus termination controller) half vdimm voltage you know is too much for the A64 mem controller at 3+ volts if so maybe adding a higher value resister in the circuit would fix teh deaths issue

I believe it has to do with something other than VDIMM.. most likely VBT (chipset voltage).

Tomarrow i'll hopefully have some time to fire up an AN50R and 2800+ (cpu deceased!) and do some poking around on the back of the board to find out what voltages are actually making it to the CPU..

I was testing out some new BH5 sticks and sometimes it would start beeping when turned on after I set it to CL3 in bios. I then had to reset the CMOS.

This happened before with my Corsair BH5 sticks so I didn't think it was a big deal, but then after resetting CMOS for the last time, it started hanging after POST :(

Tried removing the bios chip 'n reflashed it on another computer, tried removing the volt mods, still nothing.

To the people who had dead mem controllers: what were your symptoms before the cpu totally died? Was it similar to mine?

I'm hoping its my mobo cuz I ordered a K8NS

BH/CH chips cannot do cas3

question...

anyone know how to tell if the mem controller or your motherboard has gone bad?

here's my problem...

using any ratio 1:1, 5:6, 2:3, and running at 200 mhz (w/ divider in place) memtest #5 looping passes with no problems...

210 mhz no problem
220 mhz fail
230 mhz fail
...

i have 2 sticks of bh-5 that i know can do 240 mhz with 3.2 volts easy

does this sound like my mem controller has gone bad or my mobo?

and if your mem controller does go bad, would my cpu even work?

Some memory just isn't compatible with some A64 chips or mobos. That's just one of the frustrations. Always good to have a different type of ram on you so that you can test for incompatibilty vs. a part that's bad.

stevil any luck with checking those voltages? cause if its the vbt thats killing them maybe we can find a workaround to solve this issue. i was thinking it wass the vtt as some boards didnt have vbt mods. but maybe its coupled somehow with the vdimm?
