EPoX 8KDA3+ Vmods (Dimm + Vcore)

[SmokeyTheBandit]

I just got this motherboard ant off course i want to mod the hell out of this thing :D :toast:

I got some high resolution pix of some chips of wich i think have somthing to do with the Vdimm and Vcore ;)

Ill post them later tonight .

I Hope you guys can help me :D

[reject]

have you looked at motherboardFAQs?
your sig says it is fully modded ?

Your right :mad:

Forgot to correct that :rolleyes:

[SmokeyTheBandit]

Ok i figured out the Vcore mod ! :D

Put 50 k VR to pin 10 of the ISL6569CB on the top of the board.

[YoupY]

Figured out the Vdimm mod tonight together with smokey. Use a 20K vr on pin 6 of the TR9202 chip located in the right upper corner. :D

Its RT9202 :P ;)

And YoupY :toast: :banana:

[YoupY]

Will you post some pics here Smokey.

Resized please.... ;)

[blinky]

do u mean 8RDA3+ cuz the 8KDA3+ isnt out yet, only reviewers have em

how the hell did u get one?

[Tedinde]

They arent here in the USA yet. Epox comes out in europe always early for purchase.

Looks like "the" board to get!!!

what's the stock voltages on this board max out @. Epox was always generous on their voltages in the past.

[blinky]

yah this board looks awesome

[YoupY]

Hmm, I doubt it.

The board hasn't a decent multi control as far as I know. Most of the multi's won't work AFAIK. And biosses aren't very stable atm.

Also there isn't any room for attaching watercooling to the chipset, which get's pretty hot.

One positive thing about the board is that it get's it's mem voltage from the 5V.

I'm waiting for the MSI nf3-250.
Yes I know what MSI usualy stands for. Not to good, It has a working multi control (only integer numbers), and it has holes for attaching wc. Also the bios has HTT upto 300 wich may be updated to 350 or higher.
And standard mosfet cooling is on the board (dunno if it's because they get really hot, or just in case there is some serious tweaking to the board is expectd).

Also standard voltages are higher then on the epox board....

Let's wait what the future brings. I'm expecting this board next week. Will post some Vmods when I find them, unless somebody beats me to it :D

[SmokeyTheBandit]

Well as is promissed the pix of the mods ;)

I got this mobo from a shop here in the Netherlands wich had them for a day or 2 (only 20 available).

Vcore mod !!! :

Information about the Vcore mod for the EPoX 8KDA3+ :

Voltage Regulator Chip : ISL6569CB
Pin to mod : Pin 10
Pot Type: 50 k (i was out of 50 so thats why i used a 100 k )

Here are the nice High Resolution Pix !! :)

@ YoupY

Im a beta tester for EPoX with biosses and the newer betas are realy good !!!

HTT @ 350
Full Working MP Control (already worked perfect with 1st release bios)

The only thing is the max working HTT thats something they are working on.
I cant run over 300 HTT not even @ 8X MP.
But thats only a temporarily thing because the support of EPoX Rox :toast:

Im very pleased about this board because it runs frikkin fast and extremly stable :) :banana:

And this motherboard can work extremely well with BH-5 Sticks (512 MB) and it can run @ 2-2-2-5 1T timings @ 240 + FSB.
That is something i havent seen any other A64 board do !!!

Im very and i mean very satisfied with this board !!! :toast:

[xxORBxx]

Thanks smokey!! I think ill be getting this board whenever it comes to the US

I need to find a freakin 50k vr though :rolleyes:

Your welcome m8 let us know the results :D :)

[damsxx]

hello ;)

is your 3200+ a CG or C0 core ?
does in the epox bios the possiblity to choose betwenn 1T and 2T ?

thanks

[xxORBxx]

Im pretty sure you can run 1T

[SmokeyTheBandit]

Yep i always run 1T works like a charm :) :)

[damsxx]

can you run synch (1:1) with your 2x512 on epox ? more than 240 ;)
your answer can permit me to buy this MB :D

[xxORBxx]

why does it say the mem size is 256 in that pic? Bug or not your 2x512?

[Victorshen]

Hi, what is the highest stable FSB, given that the MP is low enough to keep the CPU stable

Cheers

[Demogorg]

how are the standard cores and how far u could go with no modding ?? i gonna buy a new a64 system in about 2 weeks i dont really know which board i will purchase yet

[SmokeyTheBandit]

That run is done with my extra memory wich i have ;)

2x 256 MB PC 3200 Kingston Valuream BH-5 ;)

The new biosses wich are going to be released shortly have Vcore up to 1.85 :)

Till there is a new bios that fixes the 295 HTT + bug i cant take full advantage of this board.
The board can run max HTT but when it loads windows its running the good mp but the default FSB/HTT .......

[morbidj]

Sweet man right on for the vmod info good stuff! Im sold your results are exactly what I need to see to leave my k8npro in the dust.

BTW, what are the highest default cpu and memory voltages allowed in bios as of now? What do the voltages then jump to with the vmods in affect? Lastly do you know where to measure the voltages on the board? Thanks for any info...

thanks for answer but you don't understand what I mean :-/

My question is : Can you run SYNCH (1:1) with your 2x512 BH5 on the epox 8KDA3+ more than 240mhz with good timings ??????


because your screen is done with 256mo
so if I want to buy this MB it's because I want to run 1:1 with 2x512 due to my actually MB dont' do this !!!
my MB (AN50R) does equal like epox with 256 or 2x256 bh5 !!![

[Lucus Maximus]

Thanx for the great info SmokeyTheBandit :D This has convinced me to get this board once I get a few more pay checks :)

[Jeff]

Any idea on the ETA to North America? This board looks very nice indeed. :up:

got mine here (http://www.mwave.com/mwave/viewspec.hmx?scriteria=BA20283) :D there are a few other sites selling it also.

[SmokeyTheBandit]

Oh and the Vdimm can go realy realy high been @ 3.9 :D

[Der_KHAN]

friend of mine got his board last week, saturday it suddenly wouldnt boot anymore. rma

anyone who has bad experiences with epox quality as well?

[morbidj]

Its still to soon to judge the whole line, maybe your friend received a bunk board ? Hopefully it is not the case of shotty workmanship which is doubtful in any event time will tell.

BTW will some one please send me the beta bios I have my board on order thank you in advanced.

[Mr. Freeze]

I love this board! :toast: with vcore and vdimm mods this board rules even more.Here´s results:

Epox 8KDA3+ Superpi 8M (http://koti.mbnet.fi/jiipee75/Epox%208KDA3+,SuperPi/Superpi/EpoxSpiM8_5_49.gif)

(btw... keep an eye out on the forsale forum since I'm going to be clearing out 2 or 3 crunchers to fund my A64 project... :D)

[xbladex]

Yep this board is great just recieved a new beta bios dated 14/06/04 at 300HT still doing some testing but good resaults so far

[trueplaya4ever8]

ahh does it work with true mobiles? whats the stock vdimm and cpu voltage? does it get any better with other bios.
debating on this or the msi k8n....

[blinky]

can smokey or someone PLEEEEEEEEASE test this with mobiles. pwitty pweez

[SmokeyTheBandit]

In Holland there arent any real mobiles to get :( :(
But if we can work something out with a person in the us i might be interested ;) :D :D

[xbladex]

What voltages you guys running on ya vdimm in other words what safe for BH5 ?

[SmokeyTheBandit]

Originally posted by xbladex

BH-5 is rated up to 3.6 :banana:
The A64 cpu on the other hand will not work long with that power.
So to be on the safe side for both the parts i wouldnt go above 3.2 if its a 24/7 pc .....

[esoteradactyl]

Originally posted by xbladex

with bh-5 you can run voltages pretty high (3.8-4v) if your just benching. make sure you have some cooling on those puppies :)
be carefull though. there have been many a64 deaths due to high vdimm voltage.. i would say 3.2v-3.45v for 24/7 use.

Try www.salomes-truhe.de , a shop in germany. i don't know if he's good or not. they ship to europe too. there are two mobile a64 listed, the 1,8ghz (3000+) version is available
they ship for 8,50€ (max. 2kg) to holland.

with Bh5 you can run 3.2/3.5, 24/7 on A64 platform with epox Mb due to vdimm on 5v rail

[blinky]

but i think the early A64 deaths resulted from changing vdimm in bios, with the vdimm already set high cuz of mods. i think if u just use the pots to adjust the voltage it should be fine

[Jeff]

My 8KDA3+ and mobile A64 3200+ should be here tomorrow sometime. Hopefully I'll be able to test it out tomorrow night or maybe Thursday sometime. I'm oncall this week so it's going to be tough getting a few hours of play time in. Worst case scenerio... Friday night or Saturday.

[UnderWare1213]

Anyone tried both the Epox board and MSI K8N? How do they compare to each other?

[Demogorg]

yeah that would be great i can´t decide which board i should purchase, i just dont wanna have such a bad luck like with my other mainboards before (actual the board i got right now isnt that bad but it just has a whole bunch of bugs)

[esoteradactyl]

could somebody please post some pics of where to measure the voltages. i poked around with a multimeter and found various places. some where within .1v of eachother. i want to know exactly where there at.

ive noticed the vcore voltage seems to jump when load is applied. vcore is 1.7v and when i put load it jumps to 1.79v. weird stuff. im used it to boards doing the opposite.

i have the same matter like you
my vdimm voltage when it sets to 2.8 for example can be various from 2.67 to 2.81
and when the vdimm is enable , change the vdimm various in bios
( 2.5/2.6/2.7/2.8) and reboot don't change the vdimm mesure at multimeters or in the bios

I don't understand what happens :( :confused:

its probably a bios pbm

do you think that's the same bios for 3+ and 3J MB ?

thanks

[morbidj]

http://www.epox.nl/english/support/bios/amdk8.htm date 3-1-04 I dont know what bios you guys are currently using but this is the only one I could find and it was on the epox international site.

on my 8KDA3J i have a bios of 05/05/04 , and i don't know if i can use a 3+ bios ?

[SmokeyTheBandit]

Im got a new bios 400 Mhz HTT :D:D ;)
Will give it a go tonight. :)

[Jeff]

Any mobile(DTR) support in these BIOSes? Having problems with my A64 3200+ DTR not being recognized by the mobo/BIOS(freezing at the 29h BIOS code).

[megatron]

I read elsewhere (probably on this forum) that the bios could be hacked to include recognition of mobile 64s. I have not seen any Athlon 64 mobiles for sale in UK yet.

Thinking about an early upgrade since my DFI infinity can be a handful at times.:mad:

Smokey did you ever figure out where to check the voltages on the board?

And would you please send me the beta bios or bios's Ill post them on my webspace for all of us if its cool with you?

If it is going to fluctuate like this, I am going to need to be very wary when applying a vdimm mod. I would hate to set the pot so I get 3.6 in BIOS, and then on reboot it is at 3.7. This amount of fluctuation on teh vdimm is shocking :(

[DJ_Datte]

Any chance I could get my hands on the latest bios, purty please ?

THanks!

DJ

[Coolzero2k1]

Got this board a few days ago.
With vdimm set at 2.5V and going up with the pot you will not have any instability's on the vdimm line. My only problem ist that the vcore line is very unstable although i did the vcore mod. Anyone has figured out an vdroop mod?

Greetz

[Coolzero2k1]

btw i ain't having any problems on htt 300+ running 320htt.

[gouda96]

Coolzero2k1, what cooling is that? Is that just a regular cw, because that seems like a damn nice chip you've got there.

This looks like my next board, but after my last experience with epox (lost 3 4pca3+'s for unknown reasons, first was doa, second died in 3 days, and third died after a few months) I am a little worried about shelling out $150 for a bunch of headaches.

@gouda That is normal aircooling! Thermalright SLK948 with enermax fan! This is the new stepping newcastle 3200+ they are running very good! I can recommend that board to you! Runs flawlessly with winbond memory and vdimm upto 5V :rolleyes:

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

[McSeb]

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 :D

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 :toast:

[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.

[xxORBxx]

Originally posted by gouda96

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!

[Coolzero2k1]

Here is a screenie :banana:

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 :banana: 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:confused:

[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

Greetz

[xxORBxx]

What size pots are you guys using for the mods?

[fxr91]

20K vdimm and 100K vcore here :)

[morbidj]

Originally posted by xxORBxx

Same here!

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

[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 :confused:

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

[morbidj]

I can barely reach around 1.9 but my boards vcore drops and raises so much, and 1.9 being the highest peak.

[gouda96]

Does anyone know if the 8k3aj oc's and performs the same as the 8k3a+? The 8k3a+ is a little too expensive for a friend of mine, so it is either the 8k3aj or the msi nf3 250 board.

[morbidj]

You would think the 8KRDAj would be just as nice because basically the same thing with out the extra sata controller and onboard optical outputs. Oh and the MSI sucks badly. Jfr0 has one and its a a real POS.

[gouda96]

Yeah, I bet it is the same, and if it is worse it probably isn't as bad as msi :D

[xxORBxx]

I have the 8KDA3J and its great so far. No reason to get the + version unless you need the sata and optica ports, or just have money to spend :D

Im about to do the vdimm mod right now. Im kinda worried about using a 10k pot though since QD posted his guide and he said to use a 25k VR ...

10k will be alright, wont it?

Same prob here..

I had the pchealt in bios on my screen and adjsuted the pot up an up, trying to get above 1.93.. i turned an turned until the machine shuts down :D

10K pot at 10K gave me 3.0 on the button

What was the vdimm set to in the bios? How sensitive is the VR. Like at 10k its 3.0, so how many turn would you say for like 3.3v?

Thanks

I set bios at the lowest possible, I think that was 2.5 or 2.6v and the pot was set at 10k and that gave me 3.0v. I can't tell you much more as the board died on me with the "FF" error within a few minutes. Not sure yet what caused it but already ordered another one and will be here tomorrow;)

I have seen people say set it to auto, or to the highest volts in the bios then adjust, but I have ran 3.6v - 3.9v to the mem on a64's and haven't had one die on me yet. So I'm sticking with just adjusting the vr for the volts I want and never change it in the bios. Working so far for me:p:

[xxORBxx]

Now im afraid :(

Anyone have a good story using a 10k VR?

[fxr91]

[Nomjr]

I pulled the battery overnight, cmos jumper in clear position, unplugged, and the usual things, diff mem, cpu, vid card, etc etc. Still had the ff error.

I'll have a new one tomorrow and I will go with a larger pot than the 10k, probably a 25k, but honestly, I don't think that was the problem:shrug:

[fxr91]

yeah, the old 8RDA+ was like that, dieing for no apparent reason. I had one die, so I got a new BIOS and it was still dead. I was like "WTF???" lol

[eclypse]

I just got my board runing late last night and it has the 5/5 bios?

I thought people were saying no mult control in the bios.. Well mine does and its working..

Man those voltages are crazy!.. One time i held the insert key on boot up to reset the settings and i notice my cpu was literaly cooking itself! The voltage was climing all the way up to 1.80v! I fliped out and saves the settings at default vcore and rebooted asap and it went away.. heh now on every boot i hit the "pause break" key and watch the voltage to make sure.

Nice board so far.. Just messin around with the bios and memtest atm. Later on i will attempt to install windows.

A quick question though.. Which is the better sata raid controller to use? The chipset one or the other at the bottom of the board?

[gouda96]

Did I mention I had 3 epox 4pca3+'s die on me for no reason...?!

[xxORBxx]

I would say the silicon ones at the bottom, just because of the stupid positioning of the nforce ones..dead center of the board :confused:

Have I mentioned I've had over 10 Epox boards without a single problem... well... except for a little condensation damage to an AGP port but that's not Epox's fault. ;)

[eclypse]

Can someone post a link to the newest bios? I've already maxed out the board on the shipped 5-5 bios..

[Jeff]

AOA seems to have the newest BIOSes for Epox boards. Here's the newest for the 8KDA3+/J...

AWESOME! Thank you! :toast:

stay cool now.. hehe

[jess1313]

well first i must say great work, and very got pics, and descripions.:toast:

[i]this motherboard can work extremely well with BH-5 Sticks (512 MB) and it can run @ 2-2-2-5 1T timings @ 240 + FSB.
That is something i havent seen any other A64 board do !!!
[/B]

well that is impressive but i have a shuttle sn85g4v2 with fn85 mobo(basicly a compressed an50r) it has the same Vdimm ic as the epox board you have(rt9202). im running 3.4vdimm and it is prime stable @260fsb w/ bh-6 @2-2-2-5-1t @ 1:1.:banana: :banana: . quit amasing

Considered beta 'til they are posted on the international Epox site(as far as I know at least)

[xxORBxx]

Thanks jeff. I used 2x10k VR on the vdimm and it is working great. You really have to turn the VR a lot to increase voltage, which is what i wanted so i could fine tune it better and i dont jump from 3.3 to 3.8 with a single turn.


Thanks for the help guys :D

[eclypse]

I'm not having much luck over here... I'm using the 6-15 bios.

So far if i go over 240FSB 300HTT x 8 mult it just locks.

I got the same overclock on my old chaintech NF 150 board. Only difference is that i got 2 512MB dimms installed.

[gouda96]

Couldn't that mean you just have a dud proc? That would be one lame oc'er I guess....

[eclypse]

Originally posted by gouda96

Naw.. I've had it stable at 2500Mhz on the chaintech board 10.5x238 and used 11x230 stable.

I'm just thinking either this bios still has the 300HTT bug or the locks aint working.. maybe just the sata link raid chip dont like anything over 240FSB? I'd love to try the NF raid but i'm not likin the idea of losin all the data and starting over on my 240GB raid 0 setup :eek: I've been lucky the both the chaintech and epox boards have the same stat raid chip so i didnt have to lose the stripe.

Hell i've tried raising the timings on the ram to 2.5,4,4,7 and tired going over 300HTT and instant lockin in windows or the system wont post.

If i use 2x on the LDT or LTD(whatever it is) the system refuses to post.. that bugs me hehe.. its wants 3x or 4.. I'm thinking 2x and i might beable to go above 300HTT.. I just want 250FSB on the ram and i think i'd be extremely happy for once.


Also for some odd reason this board at the same settings as the chiantech benches slower on the ram in sandra.. About 3612/3612. On the chaintech i got 3700/3700..

[fxr91]

I noticed a similar problem with the 2x multi. My system just says to reset the spoped config in BIOS... I can set 250x10 (stock) but if it is at 2x LDT, it gives me the message. If I ignore it, it boots fine, but when in Windows, it IS 2000MHz :( I have tried different multi and FSB combo's, always the same result- it sets the FSb to 200 x selected multi :(

[K32A]

Hello!

How high vcore is this mobo able to give without a mod?

[fxr91]

With official BIOSes, it is 1.7vcore max, but if you use one of the betas, it is 1.85 :)

[K32A]

Haha, nice.. Is the betas better for overclocking or what?

The reason im asking is because im considering to buy this mobo :)

[fxr91]

I had the 1.85vcore beta, but it had all sorts of stability issues with it, so I don't use it. I just use my vmods :)

[eclypse]

Hey how do you daisy chain 2 10K pots together? The 3 legged kind.

[fxr91]

Just cut off the leg closest to the adjuster end, and solder the 2 in series :)

[eclypse]

Thanks!

[eclypse]

Heres a shot of the best i can get out this usin the 6-15 bios.

[eclypse]

another..


The crazy thing is that the newest sandra version benches my ram slower at 3575/3575.. I tested it a bunch of times and its the same everytime.. I didnt change a thing in the bios.

[xxORBxx]

nice mate. Thats about what im doing. Using the 8x multi and 3x htt at like 305 htt. 2450 mhz cpu and 245mhz on my ram 3.28 v

I like this board :D

[gouda96]

What kind of cooling is that, and is that realy with only 1.6vcore?

[eclypse]

Originally posted by gouda96

Just some regular water cooling.. Yeah 1.6vcore but.. the wired thing is that when theres a load on the system it jumps to 1.7v.. What i have set in the bios.. I know someone said something like its because of the cool'n quite feature but i have that disabled in the bios and it sti ll happends.

[xxORBxx]

My vcore jumpes around like that too. at 1.7 in the bios, load is 1.79 and idle is like 1.68

its crazy

[Der_KHAN]

u should be happy. its better that way rather than the vcore dropping on load

[gouda96]

Yeah, that doesn't sound bad. Just as long as it is enough voltage to keep it stable idle. Does it fluctuate at all under load, or does it just go up and stay stable?

[morbidj]

It goes up and stays stable on my board, maybe this is a blessing in desguise no need to give it hella voltage at idle right

[xxORBxx]

Originally posted by morbidj

Same with mine. It will change a little during load but only from like 1.780 to 1.788 or something.

[gouda96]

Epox should claim they did that on purpose...sounds like cool 'n quiet for oc'ers!

Damn lazy fedex not delivering today...can't wait to get my hands on this board (j not +). I wish I had gone with a 3000 nc instead of a 3200 cw. I realy hope it is atleast a cg.

[Jeff]

My Vcore is around 1.7v unloaded and 1.76v loaded. This is with a setting of 1.8v in the BIOS btw.

http://home.earthlink.net/~adventurevision/A64-stats.png
(crappy A64 2800+ running full-load...)

[xxORBxx]

What bios are you using jeff?

[eclypse]

Someone needs to start a thread on this board in the extreme overclockers board or the AMD.. That way more people will see how good this board is and we can get more insight on bioas updates.. ect..

heh i've been wanting 2 but have been busy lately.

[gouda96]

I will leave that to someone that actually has it...like me tomorrow :D

I was thinking the same thing when I saw how many people were still buying the msi board.

[esoteradactyl]

if i ever get my prommy back i will post something in the overclocking section. the damn post office lost it. it was on its way to get gassed to r507 by chilly1 and never made it :( some day it will return.

[Jeff]

Originally posted by xxORBxx

The newest over at AOA. BUT... I think it's just a fluke with ClockGen. Setting the voltage to 1.55v via CG sometimes makes 1.8v available in the BIOS. I lost the option last night after I posted but I'll look back into it tonight to see how/when it does it.

AAAHHH!!! Holy god that sucks! Did you insure it?

So Jeff, you like the most current bios? Some people over at aoa were having bad temp readings and were flashing back, but that isn't a problem I care about.

[AcEmAsTr]

I'm sorry but through everything i've read and learnt over the few weeks i've been interested in A64, (i'm goign to get this board)
i have come to the conclusion that A64's cannot take high Vdimm, over 3.0v, the onboard mem controller just fries, killing the cpu, now the cpu's are a lot mroe expensive than the boards and people shoving 3.7volts through such an expensive chip is insane, i'd like sure confirmation that my chip will not fry if i stick 3.3v through my 3500EB, can anyone confirm this? (more than one person preferably)

Regards...

[morbidj]

Re-read this thread as you will learn the issue with the shuttle frying chips was because of adjusting the vdimm in the bios. I have had great results with a high vdimm on this board as well as plenty others.

ive had 3.45v pumping through my 3500eb since this boards release. no problems whatsoever :D

Which bios do you guys suggest?

[Jeff]

Originally posted by gouda96

Haven't had any temperature problems. And it's at least as stable as the June 16th BIOS. I'm testing my crappy "new" week 51 of 2003 chip right now and it seems very much like that BIOS except I get a little more HTT for the voltage.

[CandymanCan]

Ok guys i read all the pages on here but i dont see any beta bios with 1.85vcore.

Also ever since last night my overvolting o the cpu vcore like when i pick 1.7 i get 1.8v on load. Has no changed now it undervolts. Load is 1.7 but idle is 1.63 which sucks cuss now i cant overclock worth crap.

How do i fix this iv tried flashign to diff bios's, could it be that i installed the Cool n quiet thingy? I thought that it might be that i formatted my hdd and reinstalled windows xp and it still does this .

[Jeff]

Play around with ClockGen. I think what you have to do is boot with 1.7v via the BIOS and then set CG to 1.55v. That works for me.

Sometimes you'll actually get the 1.8v option in the BIOS. I haven't found any pattern to when it shows up though... :confused:

[CandymanCan]

Yea but when i first got this board ididnt need clockgen, i just set it to 1.7v and i get 1.7 idle and 1.8v load, now i get 1.7load and 1.63v idle....

This sucks big time it lowerd my overclock by 100mhz. because of this.

Maybe ill try to do the Vdimm and Vcore mods on this board. Where do i get those 50k and 10k pot thingy's ? Radio shack ?

Also my memory can tak about 3.3v but will thishurt my cpu? I heard alot of people saying cpus die @ 3v or more ? Also how much vcore is to much? I watercool my cpu and someone told me that 1.7v or 1.65v is to much voltage. 1.7v is like 2v for the AXP's


I looked on radioshack. com and all i see are these wierd black things. Where do i find the blue ones that Smoky used ?

http://www.radioshack.com/iphraseget.asp?perPage=25&groupBy=&sortBy=iphrase+relevance&command=text&attr1=50k+trimmer&attr2=&q=25&ia=1&s=%24__session__%24&s0=iphrase+relevance%2F%2F0&t=0&i=oid&c1=i%3A770%3BBrand%2Cdescription%2Cdescriptive+tit le%2Cmodel%2Coid%2Cproduct%2CCategory%3B10%2Ck%2Cp ot%3B%3A10%2C%3Ak%2C%3Apot%3B%2B0+%2B1+%2B2&c0=e%3A140%2F%2Fotype%2F%2F%3Aeq%2F%2Fsku&s1=oid%2F%2F1&as=1&render=1&text=50k+trimmer&sf=

[gouda96]

It seems like the high vdim killing cpu's isn't an issue with this board, so you should be fine at 3.3v. Those are 1 turn, so they are realy sensitive and can move if you bump them pretty easy. My local radio shack has the ones you are looking for, so you might have better luck driving to one.

Does anyone know what program I can use to check the 5v and 12v rails on an 8kda3j now that mbm will no longer be updated?

[CandymanCan]

So what do i tell the guy in the store what im looking for.

a 10k Pot and a 50k Pot ?

What are the full names of these things ?

[gouda96]

potentiometers, and they should be a drawer with resistors and other things like that.

[CandymanCan]

so i just look for a 10k Blue pot like Smokey's? and a 50k blue put like his also and i should be fine ? does it matter which pin i solder what 2 on the pot. Cuss isee it has 2 pins on it im guessing it doesnt matter which one i soldier from point A to B right?

Also when i soldier the wire from the pot to the chip to the mobo i solder another wire on the other Pot pin to the Screw hole on the mobo ? I guess that grounds it ?

Oh and where are these people getting those blue heatsinks they have on the Mosfets ?

[CandymanCan]

where can i get this bios that has the 1.85v option for the cpu ??

You should use the middle pin and either one of the outside ones. Whichever outside pin you use, it will change the direction you have to tun the pot to increase of descrease the resistance. Just make sure to messure that the pot is at 10 with the pin you pick and which way you need to turn.

Yeah if you put the ground to the screw hole it will ground it if its in a case, if not, im not 100% sure if it will ground. You can just find another ground on the board or just stick it in the black wire of a molex or something.

The 1.85v bios is somewhere on the AOA forums, ill try and get the link.

Yes it will still ground even if its not on case.
did my vdimm this way, made me curious now though

[xxORBxx]

I tried to on mine as well but didnt seem to work, I didnt solder it down though, i wanted to just hot glue it but that didnt work. neither did tape just i just stuck it in a molex. Ive already soldered the hot pin so right now im really confused why i didnt just solder that too :confused:

So your fo sho it works with out a case?

Did it this weekend and yes, they ground even when not in a case. So far doing 2.5 with an a64 3000 with 2- 512 sticks of geil @ 3.0v on the mem. Liking this board alot so far:)

hows the 3000+ doing? may get one, not sure, 2.5 @ what voltage? fsb/htt?benches?

Anyone manage to get a lower mult then 8 on this board? If so what bios?

I still haven't had time to play with it alot, but the 3000 is at stock voltage for 2.5(10x250) on plain old water. I'll try to get some benches in later tonight when I get home.

[CandymanCan]

Same with water and stock voltage @ 2.5ghz, but anything higher even 5m hz and my thing becomes un stable even when i use voltage all the way up to 1.85v....

Something is holding me becausei can get 3130mhz to post when the pc is turned on.

[shimmishim]

hi

i just got this board today and haven't booted it up yet...

so a summary of this thread kind of:

teh newest beta bios has the voltage option up to 1.85 but only appears sometimes....

as for the vdimm mods and vcore mod, i assume that it works also for the 8kda3J even though it doesn't say so in the title :)

the voltage goes up under load is this correct?

the both 8kda3+ and 8kda3J use the same bios...

does this all sound correct?

also, when adjusting the vdimm and vcore voltages, is it best to just leave it at the lowest setting in the bios or auto and adjust it with the pots?

[gouda96]

That's all correct...but don't worry about the 1.85v option. You can't realy use it, so just do the vcore mod. Do a64's mind high volts or can you go up to 2v+?

[morbidj]

In my experience after about 1.85 or so the processors I have worked with stopped responding to voltage increases.

[CandymanCan]

Guys why is my cpu acting like this.

I can get 2509mhz stable @ 1.6v, but when i go to 2515mhz or higher even when i use 1.65-1.7-1.75-1.8v it isnt stable at all. Prime95 failes within 2-10 minutes.

Why does this happen

How are your temps?

[fxr91]

I have teh same prob with my 3400+. It is a C0, but when I had my AN50R, I could do 2780 stable 24/7. With this 8KDA3+ , I can no longer get over 2.5GHz :mad: And I have a goodamn Vapo LS so temps are not a problem....

[Kunaak]

anyone have pics of these mods?

[xbladex]

first page of this thread bud

[CandymanCan]

Man this sucks my cpu can do 2650mhz, in windows just fine but anything past 2509mhz and it gets unstable ...... GRRRRRRRRRR

Why does this happen i know my cpu can do more the 2509mhz, ........ My temps i ave watercooling they never go above 46c, the other guy is having the same problems @ 2509mhz he used to get 2780mhz... If this boards the cause of that then its ganna go out the window because im not about to be held back by 150-200mhz verclock because of some defect in the mobo.


Ij ust got the 10k Pot it has 3 little things sticking out the bottom, which ones do i use for the vdimm mod. ?

[fxr91]

Yeah, it is seeming like a speed limit imposed by the motherboard :( If that is the case, I will be getting the AN51. Never had probs with my AN50 so I like the boards.

Maybe the speed restriction is related to the LDT voltage option not being adjustable in BIOS? Seeing as you cannot utilise the 2x LDT setting in BIOS...

[CandymanCan]

What LDT voltage u mean the HTT frecquency. Only 3x and 4x are stable for for me.


Btw about the 10k pot i have it has 3 pins which of the 3 do i use for the Vdimm mod ? Do i use the middle one and solder that to the chip on the mobob and then one of the side pins solder to the Screw holes to ground ?

[fxr91]

Yeah, I mean the HTT Freq voltage. You can't adjust it, which would allow teh baord to be more stable with higher HTT Freqs.

And if you use the 2x HTT Freq option in BIOS, it sets your FSB back to 200 and tells you to reset the cpu parameters :rolleyes: This seems to be a great board for overclocking IF you don't intend on running it on anything other than air cooling...

The middle pin goes to the IC leg and either of the end pins can be used. They just determine which way you need to turn the put to adjust the resistance. I use the bottom pin and that means the adjustment is made anti-clockwise to increase the voltage :)

[CandymanCan]

Btw, youre right about the LDT.

Im right now using the 2x LDT setting andn ow Sandra's multimedia test works @ 255x10 or 2550mhz.

See for me to see if my cpu was unstable besides prime95 Sisoft sandra multimedia test the Integer one or the orange test would alwaysg et like 1100 while the blue one would get like 26000.

Now it works just fine and prime95 hasnt failed yet. Now if i can only figure out how to get the 2x LDT to work @ high HTT speeds. It seems to not like working @ high HTT speeds. Are thier Vmods for the LDT voltage ? I know some mobo's have them so maybe someone who knows all this stuff can come up with something.


Edit: blah Someone who knows alot of vmods like maybe smokey can come up with a LDT vmod. Cuss this sucks how so many people uncluding me are being held backbecasue the 2x LDT setting doesnt work correctly.

[fxr91]

I couldn't get the 2x HTT Freq to work at any speeds :(

[CandymanCan]

Yea it works for me but barely.... Oh well looks like 2500mhz is ganna be my max Until someone comesu p with a LDT vmod. Why in heck didnt epox put this in thier bios ?? ..

[morbidj]

I dont get why you want to use x2 any ways? I have had prime stable HTT's @ 250+ x4LDT It should handle 1000MHz easily and then some ?

Is there a particular other reason that you might be held back by?

[CandymanCan]

You dont understand do you :P

I can get 325HTT 4xLDT prime stable also but that is @ 2400mhz.

We a re stuck @ 2500mhz, even with a 3xLDT anything higher will not work.

When i went a 2xLDT it finally worked @ 2550mhz. I am Able to into windows @ 2650mhz with4xLDT and 3xLDT but it isnt stable and now i found out its because the LDT speeds were to high. Its wierd i know.

See i can get 2509mhz stable @ 1.6v with 45c load temps. But @ 2515mhz even when i use 1.65-1.75-1.8-1.85v it isnt stable.

Its seems the higher in MHZ you go the more LDT voltage you need, but since thier is no LDT voltage option the 2LDT is the choice to use.

See the other guy got 2780mhz stable on his board that had a 1.5v max LDT option. Since our board dont have the LDT voltage option were stuck @ 1.2v, and because of that his cpu is now stuck @ 2500mhz.


Anyway FXR91, try the beta 06/30 bios. With that i can get into windows with the 2x LDT

[Jeff]

I've run stable at 2.6GHz with the 3x setting. And look at Smokey's siggy(you know, the guy who started this thread ;))....
Athlon 64 3200+ NC @ 2900 Mhz +
EPoX 8KDA3+ Vdimm + Vcore modz
Prometeia @ R404A
2x 512 Mb Twinmos BH-5
2x 256 Mb Mushkin PC3500 LVL2
2x 256 Mb Kingston ValueRam BH-5
Radeon 9800 Pro @ XT (520 / 420)
DD Maze 4-1 Cooled @ (GPU)
Swiftech MCW 50-T @ (NB)
Enermax 550 Watt

He's running 2.9GHz so I don't beleive there's a 2.5GHz ceiling for the 8KDA3+/J.

[CandymanCan]

Belive what you want, but me and the other guy are hitting walls thier and im blamming it on the lack of LDT voltage now.

Btw he is using a prommy and vcore and vdimm mods i have none of those.

You say You have run 2.6ghz what happend ?:rolleyes:

[eclypse]

3X was the lowest setting i could choice for LDT.. Any lower and the next boot it would say that the CPU settings were reset cause it wasnt stable..

[esoteradactyl]

why in the world would you want to use a ldt of 2 or 1?? talk about a decrease in speed. seems like your more interested in having a high htt rather than having overall performance.

[fxr91]

Nothing about wanting to use it in everyday use, but if it is there in the BIOS you 'should' be able to use it. Especially when it comes to benching, the higher the HTT and CPU speed the better, which unfortunatley I lose boith with this board... I will now probably be going to a VIA with PCI/AGP locks after using this board.. It is crap as I have lost 280MHz on my clokspeed with the only difference being the motherboard :rolleyes:

[Jeff]

Thanks again Smokey for the damn fine work. :toast:

And thank you to Epox for not using a chip with angel hair pins to control the voltages. :lol: ;)

[eclypse]

Me i'm injoying the gig of ram for once!

I think its all just bios related and they'll get it right sooner or later.

[a5h]

i have read most of the thread ....but i have a Epox 8KDA3+ on the way ...

and i was just wondering how all you 8KDA3+ owners are getting around the stock NB heatsink. You all know it has no mounting holes around the NB and i won't settle for that little tin sink ...so how do you strap on a nice fat heatsink /w fan? pix wud be nice.

[eclypse]

I never bothered to change it since i'm just testing out if i'm gona keep the board.

If ya want to use something bigger i believe the only other methed would be to use some artic silver epoxy. Though i wouldnt advise using some huge heatsink with alot of weight since it might end up taking the whole chipset off in a case.

[gouda96]

Small Al cpu heatsink would be fine to epoxy on. I realy wish they had included holes though...realy makes things easier.

[a5h]

the Epox socket 939 board has the exact same layout as the 8kDA3+ ...BUT it does have mounting holes (if my eyes seeing straight).

look for a pic of the 939 board here (just scroll down):

clicky (http://www.short-media.com/forum/showthread.php?t=11454)

do i smell a drilling mod to make mounting holes :D :toast:

[a5h]

the holes arn't being used on that board tho :confused: ...and are spread wide apart.

[gouda96]

Yeah, they are realy far apart. You could fit a large cpu hsf between them. That's annoying, they FORGOT to put them in the 754 board...Don't know about that drilling mod either :D

eclypse, holy crap, I just noticed your avatar...that is the most kickass shirt I have ever seen. Where can I get one of those? God damn I need one of them. I get 20 calls a day with people asking me computer questions. You would think I could start a business and make some good money, but everyone that calls me is too cheap to buy reliable pc components and that is the reason they are calling me in the first place.

The two mounting holes for the mobo align themselves right down the center of the northbridge. Someone creative(unlike myself) could probably figure something out using those too. ;)

I wonder how well a zip tie would work.

[Verdict]

i get epox tomorrow, lets see what i can do with that :D

i drive some test C02 with K8N and 3400+
i got Superpi 8m : 5:23 and 1m : 29sec

lets see how epox works with that prosessor :toast:

[eclypse]

I have a feeling this board needs a chipset mod as well.. Anyone?

[Verdict]

Tell me what is the best bios for that mobo, i test newest bios from epox site and it really SUX, then i but first one back

:confused:

[mesyn191]

Hi guys I'm a total soldering nOOb, but looking at the pics @ voidyourwarranty.nl the spots to solder look pretty straight forward except for the vCore one. I can see where one of the wires is soldered to the chip and goes to the pot, but then there is another wire that comes off the pot and goes somewhere else but you can't see where in the pic.

Anybody happen to know where that other wire goes, or is this just one of those things that you're supposed to know if you actually know something about electronics (I don't, I just want to see how high I can get my chip)?

Any other tips on modding this motherboard would be greatly appreciated.

Thanks!

It doesnt need a mod it tracks automatically.

I like 6-14 bios the most.

The other wire goes to a grounding location such as a mounting hole.

The other wire goes to ground.. So one end goes to the chip and the other goes to ground.. Thats usually the norm.

Ground can be a screw hole or fan header.. I like to use the ground pin on a fan header using a fan header plug.. The black wire on the fan header plug is ground BTW.. This way if something goes wrong or your going to flash the bios or dont want to leave alot of evidence of a mod done you can just unplug it and it will dissable to mod..

Just find a old fan that has the female 3 prong header.. Cut it off and splice the black wire to the wire your going to use on the VR as ground and plug it in and your good to go.

Just make sure not to turn the vr too fast when your in the bios or your blow either the CPU (vcore mod) or the memory + CPU (vdimm mod)

I like to make the adjustment with the system turned off.. Also dont unplug the mod ofcourse while the system is runing hehe.

Good luck!

and i can find that bios from ?????????

thanx :toast:

[mesyn191]

eclypse: thanks for the help, now I just gotta get those pots and practice soldering on some junk I have lying around the house.

PS: you can get those pots from Radio Shack right? Or would I have to order them online?

[eclypse]

You can try radio shack but mine dont like to stock the right ones that are needed like the 50K.. Just mainly 1k-10K.

The 15 turn long blue 1/4 watt 50K is best.. Just make sure to first set the vr to 50k "MAX" before hooking it up. THat way theres no resistance on it and its like having it turned off so you dont over due it on first power up.. Then i guess while your in the bios turn it very smooth and slowly till ya get it right where ya want.

Though i'm telling ya to make sure the vcore is level before you do so.. this board is crazy sometimes where you can set it to 1.5v and it can end up at 1.3v on next boot so.. make sure its at whatever ya set it at on next boot before you start adjusting the vr.. or ya right the prob of haing the voltage really jumping 0.2+ on ya on the following cold boot.


Oh heh.. yeah if ya want the good 50K vr buy them online at http://www.circuitspecialists.com/level.itml/icOid/6945

[mesyn191]

Hey thanks for the link, that makes things much easier.

I seem to be one of the lucky ones and have a motherboard where the motherboard doesn't vary that much, only by about -/+ .1 or so. Of course it could also be like that because I've overvolted my +3.3v, +5v, and +12v lines (I have a Antec Tru Control 550w PSU) I really wouldn't know for sure though. I would set the voltage to the lowest possible in the BIOS before starting to use the pot though right?

Another probably stupid question for you:

I can't really tell in most of the pics as most of them aren't closeups, but when soldering the wire to one of the chips would you first desolder the post that you wanted, lift it up off the motherboard and then solder the wire to it or can it still be attached to the wire and the motherboard at the same time?

Thanks for the help man:banana: :banana: :banana: !

just solder directly to the leg ;) no need to desolder anything.

Lo, I only scanned the thread, but did you get your Mobile going on this mobo?
Just wondered as I just booted mine :D

Cheers

[morbidj]

You just booted your mobile? As far as I know your the only person that may be successful with this board and a mobile, Jeff posted that his was incompatable and he sold off his mobile. Another fella posted also that his incompatable. Please list your details such as your board revision, Processor type and model #, and bios revision.

[Jeff]

I could get it working if I used a desktop chip to set it the multiplier. "Auto" wouldn't work for me and didn't allow my setup to get past the "C9" BIOS code.

The bummer for me happened when I had the mobile running and I pushed too hard. The BIOS would reset and I'd have to swap back my desktop CPU to get the mobile working again. That's just not fun when your trying to have fun. ;)

[Bulldog20]

Lo, mines ok, well had to vmod the vcore because it defaulted to high multi/low vcore = x9/ 0.9v. Volt mod to 1.3v and voila boots.

Only problem so far is I can't get passed 270 FSB, the PCI doesn't seem to be locked ? I thought the Epox had PCI lock?

Edit, this board is weird :(

Cheers

[Bulldog20]

Lo, my motherboard is v1.0, not sure on the chip, it's alittle tied up atm :)

I did the same on a K8NNXP, just had to mod the vcore before it would boot. I posted a thread in the vapochill forum.
http://forum.vapochill.com/showthread.php?threadid=7052

[Bulldog20]

Well goto the 300 barrier, it seems to be stable, 1 more mhz and it locks.

[kakaroto]

Does anyone know wich mosfet i can read the Vcore?

The 2 mosfets aroud the ATX connec, gives me strange vcore.

[Bulldog20]

Lo, I measure mine on one of the coils. The leg nearest the I/O panel. Top left, can't miss them.

thxn, now ive got better measering. 1.59v instead of 1.48v

This only cause i picked another ground (probe).
I picked a molex 4 pin for getting my ground. There are 2 black. (GND) Two ground give me 2 different measering.

Why...

Cheers wait so did it not boot initially and did boot with a vcore mod????

or it booted out of the box except with 0.9v vcore????


how come this guy can get mobiles working and no one else can???

[Bulldog20]

Yes m8, just a vcore mod. So out of the box with a vcore mod. I posted this on my forum weeks ago.

"how come this guy can get mobiles working and no one else can?? "

What does that mean? Not sure if there is a complement hidden in there somewhere :) I have been clocking for a little while ;)

When I measure there, I get 1.3V when it's set to 1.7 in the BIOS. That can't be good.

[Bulldog20]

Lo, a yes it works here from that point, either bios adjustment or pot.

[jonspd]

Do these mod's work on the J version as well instead of the +?

[eclypse]

YES

COOl thank's I guess I will have to read this whole thread when I get my board LOL

[Jade]

So is THIS (http://users.bigpond.net.au/fxr91/bios/kda34615.zip) still the best bios floating around??

And where are people getting this 1:1 FSB/DRAM in cpu-z from?? All I get is "CPU/#".

[Silver]

Just a thanks for the vcore/vdimm mods. Have not done the vcore yet however the vdimm mod along with 6/14 flash changed the board dramatically for me. RBX along with 3.1v on ram and she will run to 2727 primed. Will boot and do some light benching at 2750 (cpugen is overvolting to 1.85v under load). Used 10kvr on vdimm. SuperPi 1 meg is 33 seconds, 2 meg 1 min 16 secs. and 6800gt w/ultra flash is doing 28,100 (27,100 without). Chip is 3000+ Newcastle. 9 x 303 at (166) 2,2,2,5 1T 4x. Vdimm is a good mod. Ran the 320w tec past DD on a maze 2-1 and they think on the 1/4 inch plate and 1/2 nipples the block should handle 10v. Will be giving it a go along with the vcore mod and dual rads in cooling box. 2.8Ghz should be achievable, now as for 2.9Ghz.....that is another story.

[Jade]

Hmmm, I cant get mine to 1:1. THe lowest it goes to is cpu/10....when my multi is 8x. If I raise my multi the cpu/# just goes up! >_<

These a64s confuse the crap outta me. The more I read about them the more I am lost.

Can someone takes some pic's of there mod's so I can have something to go by the one's on the 1st page have seemed to stop working?

Heres the origonal pic of the Vcore mod.. I believe the line you see goes from that leg to a 20 or 50 Vr then to ground.
