I believe thats the beta of 28/5 dont know for sure though.

Will upload every bios i have tonight onto my webspace for ya all.

Im kindof a n00b with this stuff, but i've decided to buy an AMD64 system...
I would like to know if there is any guides to overclock the amd64?
and where they are of course

this is my system:
Athlon 64 3200+ NC
EPoX 8KDA3+
Any 2x 512 Mb
Radeon 9800 Pro

But i dont know which memory to use :P
Give me some good suggestions

Wow, that answered alot of questions!

Since that board uses the 5v rail for the vdim, that means that there is no risk of damaging the cpu with high vdim because the 3.3v rail can be left at 3.3v right?

That is one kickass clock for air, hot damn you've got a nice setup there

[xxORBxx]

No you can kill the CPU just as easy if the vdimm is on the 5v rail. No matter what rail, the mem controller could die at high vdimm (3.2+)

The shuttle AN50R which was know for killing cpus had its vdimm running off the 5v line.

[gouda96]

Damn. I wonder how the nc's respond to high vdim.

Im betting the same way but ya never know. That would be sweet if they didnt have this problem.

[Coolzero2k1]

Currently i'm running 3.7V on the mem, and there is no sign that it will be dieing in future, had killed 3 CPU's before with the an50r! I think the matter why an50r was killing so many cpu's on high dimm voltage was the instability on the mem voltage!

OMFG !!! I hope thats true. I killed my 3200+ on the AN50R. Thats POS board

Here is a screenie

Not the max i can do, will top out the ram soon

[LBJGH]

Hoping you guys can help me out... I'm having random hard-locks, Windows XP won't shut down and I don't have the multiplier control in the bios. (I'm currently using 06/15/2004.

I think my problems may be associated with my freak 3100+ A64 (recognized as 2900+ in bios).

[morbidj]

I had issues like that using the 6-16 bios so now Im running the 6-14 and all seems well. I have my bh-5 running @ 255MHz 2-2-2-6 prime stable with 3.4V I will run it every day with 3.4V but do I dare run it at 3.5+V every day, any one with any luck do it with out frying the ram?

[xxORBxx]

Id personally be more afraid of killing the CPU. Isnt BH5s vdimm limit like 3.6 ?

[gouda96]

Bh-5 laughs at 3.6v. I have seen past 4v, but most stick to 3.7v-3.9v for benching it seems.

I would realy like to know how procs react to high vdim in this mobo.

[morbidj]

Well lets find out, Im getting rid of this Clawhammer 3200 I have now in 3 days so lets see what she can do.

[gouda96]

Run like 3.7-3.8v and see if she makes it for 3 days. I would think if the chip could make it for 3 days that would probably mean 3.3-3.5v should be pretty good for a while.

[morbidj]

Sounds good to me what do you think I should throw at it some prime95 loops?

[gouda96]

yeah, sounds good. Are there any mem benches you could loop at the same time? I don't think either would realy affect the ammount damage inflicted on the cpu by high vdim though, but couldn't reduce the damage either.

[morbidj]

I'll try some 3dmark 2001 with software emulation on, that should work the beast.

[Nomjr]

anyone have the measure points? mine passed on with the FF error

[Coolzero2k1]

So running 3.7V for about 2 weeks now, think this board doesn't seem to have such problems on high vdimm and damaging cpu's. My An50R f*cked my a64 up with 3.6V in only 5h lol

What size pots are you guys using for the mods?

[fxr91]

20K vdimm and 100K vcore here

Same here!

5 Days and the processor was all good at 3.7 Volts also!

[fxr91]

Does anyone else have this problem? The vcore reading stops registering once you go up over 1.93v on my board, and just sits at 1.93v no matter how much you wind your pot up

I know for a fact I had a load of voltage going through my cpu until I realised this was happening, as even with the VapoLS, my CPU temp reached +33C It would have had to have over 2.2v running through it to get to that At 1.9v, the cpu sits in the negative C's...
