Any idea if this affects Socket 940 Opterons and Athlon FX'es?
I'm going to buy:
Opteron 240
ASUS SK8V
512MB PC2700 Regd'ed ECC.
I'd prefer Opteron so I can move back into Dual heaven later on, and having a server processor makes you feel so much more badarse :)
Last thing you want is your machine crashing at 12 midnight in a middle of a game
U're probably right mate, this could be an issue but I've been using the same pots for alot of mods, including my 9800's ones and something like this has never happened before...Quote:

i mean, normal pots are supposed to stick to the before set resistance, but they don't guarantee linear resistance while actually TURNING the VR!!!
Only precision VRs are supposed to act in a linear way while changing.
So - if you change the resistance on the VR under current you take the risk of wrong values for a short time.
just a thought...
Better safe than sorry though, so no more "live" tuning for Vmem, :)
Never encountered any problems whilst raising the voltage, i just turned the VR's very very slow and the voltage came up nice without ever spiking or anything.
I used 2x 1K 15turn pots and had to give them a lot of turns to start off but then the increase in voltage happend faster and faster.
So once it goes over 3V turn it very gently, it will raise fast.
Hey Jeff I didn't have that happen to me last week ( heheh)...Quote:

If people are affraid of sounding like an idiot, get over it... I'd rather hear from an idiot than from nobody at all(or someone after the fact saying "yeah, I had that happen to me a few weeks ago"). ;)
I dunno why it's dying bro, but I would hope someone that had it happen would chime in as Randy and Bowman have......
Good to see you guys.

Anyone killed an A64 specifically by raising the 3.3v rail too high? My vdimm is chillin at 3.38v right now, but I'm still having issues getting my memory bus up very high, i have to run a 4:3 divider or higher, my HTT bus doesnt have any problem going up now, but still not much luck on the mem bus. Only getting about 210mhz at 3.38v 2-2-2-5 and this is bh-5?? what gives?
Try and take 1 block of memory out and only use 1 stick in slot1.
Ya i already know that that allows me a higher mem bus now...but I'd rather take a hit on my mem speed then have to go down to only 512megs...Planetside would die...
just wanted u guys to know, the 3000+ CG stepping boxed is available by now
edit: its already a newcastle
You were right. RMA finally got approved yesterday. Don't know what the fault was though.Quote:

Well, glad to see that you isolated it. A mobo killing chips is not an easy thing to isolate.
is this chip good?....im new to amd64 though...need some advise... :D
i do. im running this an50r with no volt mods. i run my memory at 2.9v cpu 1.6v the rest set to auto. the oc is done thru the bios using 230x10 2.5 LDT 1:1 so far nothing has died? been about two months so far so good. ill let you gys know if anything dies from me using just what the bios has to offer?Quote:

Just curious, has anybody tried overclocking an A64 board without doing any extreme volt mods and just using the voltages in the bios?
Before you throw things at me for asking that, I'm just curious from a testing standpoint if anybody has killed anything just using bios settings.
Thanks,
Kosmic
later perc,
Very similar to mine.Quote:

Not the best of clockers but i think it might be something to do with my psu. It did 2349mhz 3d on water 1.65v. In my gigabyte k8n. And 2269mhz on air.
i think my 3000+ cg newcastle is dying too, but why?
i got a vmodded an50r (vdimm/core) and changed the VRs live, but never had/noticed spikes (bios reading).
max vcore was like 1.75 and max vdimm 3.2, never went above. wtf is up with the 64s?!
but hey at least the cg was supposed to have an enhanced mem ctr l:stick: :D
friggin stuff, i'm pretty frustrated right now
One word: diodes.
Care to elaborate a bit on that?Quote:

Hm I'm thinking of getting an A64 system, now I'm a bit scared of sudden deaths. :P
So is any NF3 board safe to overclock, because I don't want these damn pci/agp dividers. I got some kickass BH-5 ram here and I don't want it to end up at 200mhz :P
So what about NF3+High FSB+High Cpu Clocks ?
And maybe should I wait for socket 939 ? (don't have that much money)
I sat back for a bit to see different peoples results from the various NF3 boards.While the shuttle boards seemeed tempting because of their price, they also seemed flaky at times. I opted for the gigabyte K8n-pro and aside from a bios issue I had from the original revision of the board (which was resolved when i got a newer rev board) I hvaent had any other problems. As far as sudden death syndrome, I havent seen any of the symptoms, I have my 3.3v rail at 3.7, and my vdimm voltage at 3.35v and so far so good, only thing holding me back for now is my cooling solution. I havent really decided on the whole s939 thing, as I am not all that convined that dual channel is gonna help all that much, let alone the fact that all the 939 athlon64s will only have 512k l2 cache. So unless you wanna put down the "cache" for an 939 FX, I would recommend sticking with the s754 solution, as it seems it'll be around for awhile.
oh btw: High HTT frequencies dont really seem to bother asny of my system components, just look at my sig for my clocks :)
So I should get a Gigabyte board ? What mods did you do to it ? And on what cooling are you ?
