I can barely reach around 1.9 but my boards vcore drops and raises so much, and 1.9 being the highest peak.
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.
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.
Yeah, I bet it is the same, and if it is worse it probably isn't as bad as msi :D
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..Quote:

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...
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
Any permanent damage?Quote:

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?Quote:

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;)Quote:

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:
Now im afraid :(
Anyone have a good story using a 10k VR?
I had the same problem on teh weekend. I pulled teh CMOS battery and set the CMOS CLR jumper to CLR for 15 minutes and it came back to life :)Quote:

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

Can someone post a link to the newest bios? I've already maxed out the board on the shipped 5-5 bios..
AOA seems to have the newest BIOSes for Epox boards. Here's the newest for the 8KDA3+/J...

AWESOME! Thank you! :toast:Quote:

stay cool now.. hehe
well first i must say great work, and very got pics, and descripions.:toast:
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 amasingQuote:
[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 !!!

Anyone know if these BIOSes are beta or official?Quote:

Considered beta 'til they are posted on the international Epox site(as far as I know at least)
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
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.
Couldn't that mean you just have a dud proc? That would be one lame oc'er I guess....
Naw.. I've had it stable at 2500Mhz on the chaintech board 10.5x238 and used 11x230 stable.Quote:

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..
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 :(
Hello!
How high vcore is this mobo able to give without a mod?
With official BIOSes, it is 1.7vcore max, but if you use one of the betas, it is 1.85 :)
Haha, nice.. Is the betas better for overclocking or what?
The reason im asking is because im considering to buy this mobo :)
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 :)
Hey how do you daisy chain 2 10K pots together? The 3 legged kind.
Just cut off the leg closest to the adjuster end, and solder the 2 in series :)
Thanks!
Heres a shot of the best i can get out this usin the 6-15 bios.
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.
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
What kind of cooling is that, and is that realy with only 1.6vcore?
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.Quote:
Originally posted by gouda96

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
u should be happy. its better that way rather than the vcore dropping on load
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?
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
Same with mine. It will change a little during load but only from like 1.780 to 1.788 or something.Quote:

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

(crappy A64 2800+ running full-load...)
What bios are you using jeff?
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.
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.
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.
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.Quote:

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.
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...
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 :DQuote:

Which bios do you guys suggest?
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.Quote:

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

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 ?
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
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?
well i didnt have a brass thingy or a screw, worked fine, not sure how though lol
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:)Quote:

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.Quote:

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?
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+?
In my experience after about 1.85 or so the processors I have worked with stopped responding to voltage increases.
How are your temps?
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....
anyone have pics of these mods?
first page of this thread bud
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...
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 :)Quote:

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 ?
I couldn't get the 2x HTT Freq to work at any speeds :(
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?
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 ;))....
He's running 2.9GHz so I don't beleive there's a 2.5GHz ceiling for the 8KDA3+/J.Quote:

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..
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.
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:
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: ;)
