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?
anyone?Quote:

Like I said earlier, you need extra available hardware so you can swap out parts to isolate your issue. Did you try running a single stick of bh-5 to see it's FSB limits? Have you tried different ram? Different ram slots? What's your vdimm? Are your ram stick double sided or single sided?
i have single sided bh-5'sQuote:

i ran 1 stick in each slot and still have problems
i ran 2 sticks in 1/2 1/3 2/3 and no good
vdimm is set to around 3.2 to 3.3 usually for any HTT i use.
i've tried my memory in other boards and the memory is fine.
i've tried another epox 8kda3j and was not able to hit 2.75 stable
anything else?
i've never heard of a chip not being able to hit it's highest overclock after installing a new piece of hardware
allm y problems started with an x800 (which is now dead due to a psu problem)
stuck an x800 into my system and system was not stable.... after sticking it in, it wouldn't hit 2.75 stable anymore... so i took it out and put in a 9600xt and it still wouldn't hit 2.75...
someone suggested a larger psu so i went from a 430 to a 520 and fixed some problems but still maxed out at 2.4 ghz...
couple days ago, my power supply crapped out and killed my x800 in the process....
so... is it the mem controller on my chip or is it the board?
the other board i sold off to someone else with mods intact and they have been able to hit 250 HTT (2.5 ghz) with their board and air cooling....
but i don't see how 3.3 volts could damage my mem controller and how my chip would still be working even with a damaged mem controller
thanks.
I ve killed a 3000+ with too high VBT , with pc3200 it didn't boot , but with pc2100 it will !!! lolll
Mem controller knocked out.
so you're saying that it worked... just not at pc3200 speeds?Quote:

interesting... maybe i do have a damaged mem controller then...
thanks misteroadster! :)
Well, that the first I've heard of a "damaged" mem controller. I've heard of various incompatibility issues and that's all. Shim, you need to try your chip in a different model mobo and/or try a different chip in your current mobo. In my opinio, it's worth buying a piece of hardware then paying a 15% restocking fee just to get it checked.
