Because the site is run by a Gay Hitler type character named Daniel and the Epox tech guy is some kind of communist. You think I'm joking right? Hang out there are see. Most of his "followers" are sissy's licking his boots. Ask them something they don't want to answer and they'll ban you. Challenge what they say and they'll ban you. Mention another brand name too many times and they'll ban you.

In other words it's a dictatorship and some kind of weird gay hardware cult.

hahahahahahahahaha Thanks man, best laugh I've had all night. It didn't want to say anything, but thats kind of the impression I got.

Aaron

Those guys over there are not very tolerant of any out of line questioning and name pushing.:)

Why can`t you just replace the burnt out chip ?

Is it possible to get such a chip somewhere ?

As opposed to other epox techs that participate in other forums and add credibilty to Epox and their support of end users.

Seriously I think if anyone from Epox Marketing spent anytime reviewing the tone of AOA's Epox section they would be thoroughly embarassed and shut it down.

Thankfully there are epox tech's that participate here and at AMDMB.com

Shad

I have seen that Epox tech completely DELETE whole threads because he didn't like the "tone" of the questions.

Questions like: Does the 8RDA+ lock the PCI bus?

Questions like: Does the 8RDA+ unlock all multipliers like the 400
boards?

Questions like that from poor people who bought the product and are looking for answers get the "communist" treatment. Then, you get a speech about your life and what kind of person you are for asking thse questions by Daniel the stupid stuck up gay bully.

You know what? A guy like Daniel needs to have his little ass kicked in. I bet he wouldn't speak to people fact to face like he does behind his computer. If fact, I wish I could meet him face to face.....

I don't have seen what you said but Daniel and EPoX tech are both helping a lot of EPoX users who have problems.

Fanboy?

:confused: :rolleyes:

soldier2000, it's true that they help people. I am not totally against them since as a user I got to listen to the rule as well.

At the same time, they appear to be very strict to thier(?) own rules that they(?) created. However, those rules seem to put a limit to their serviceability and the way that they think.

put it the other way, a modern business concept, the customer is a king. That is the wisdom of how to treat a customer in a highly competitive market.
If E or H want to help, there might be other alternatives for them e.g. they might use other names or thru other people to log into the system and provide some explanation unofficially that do not violate their own NDA. Then, the number of complaints will be greatly reduced, I believe.

Another example of how to treat a customer's problem. Many customers faced a screen-flashing and 3-mouse-pointer problem when running at FSB > 200, 210, 220 (it depended on the configuration). One customer found a solution (Vdd mod--a solution not from Epox). E responded in a thread discouraging people not to solve the problem that way because it might kill the board. E's intention is good. However, E did not provide any alternative to solving that problem safely. On the other hand, H provided info on how the problem might be solved but warned that to do it at own risk.

That's true

Look all I'm saying is it is real crappy that there are people out there like Daniel. I read through a ton of threads over at that site and couldn't believe what I was seeing. Maybe I'm an idealist, but I believe that the internet is supposed to be a free exchange of ideas. I don't believe in deleting posts (with the exception of criminal behavior). But just shutting someone up because you don't agree with them, or you don't like what they have to say is just wrong. Clearly a lot of people agree. And some of them sound pretty pissed about their experiences with him and his site. Just read the previous posts in this thread and you'll see he's not real popular with a few people.

What's this guy like in real life? I don't know, could be a great guy, he could be the next noble laureate or he could be an annoying insecure obnoxious little know it all twerp who needs to have his ass kicked a time or two to snap him back to reality.

I’m not making any judgments about him or his “boot licking” subordinate lackey fan boys (teehee had to say it) as people, I’m just saying it shady how they run that board.


Aaron

(ok maybe a little judgement)

Back ontopic:

I had a chance to test my CPU and RAM i was using at the time my Vdd-modded epox 8rda+ melted.

In contrary to my vidcard, they still work fine. =^)

Running a XP2400+ on a KT133 chipset now, lol. :D

I was banned on that board for saying "I dont think the 8RDA+ has PCI lock", heh.

And well you should be, blaspheny!!!:D

RichBastard,
I had thought that you burnt the IRU3037A.
But it is that IRU7313 that was burnt.
Why don't you try replacing it? IRU 7313 is simply a 2-power-mosfet-in-1. I think that using a 2 separate power mosfets might do the job as well.

I haven't got the tools to desolder chips, and i sure don't know where to get a IRU 7313 chip in Belgium. :s

On page 7 of IRU3037 document, they provided a recommended spec of power MOSFETs.

Vdds 20V
Id 5.2A
Rds on 0.05 ohm

or from IRU7313 spec sheet:
Vdds 30V
Id 6.2A
Rds on 0.029 ohm

I think if you go to an electronic shop with this spec, you might get them (2 units). You can also get a higher/better spec.
Don't worry. You won't kill the board again. But you will need to do some messy soldering work.

On the other hand, I recall seeing some electronic shops in the US that carries a whole range of sophisticated electronic parts but I could not remember the exact site. try searching in the internet, if you want the same exact replacement.

Thanks for the information, i appreciate it.

I will look into it after my exams. :)

BWHAHAAHA

:rotf: :hehe:

Don't worry. I heard that Epox will include Vdd adj in the next revision of m/b.
Pls don't ask this question at aoa/epox m/b forum. It might not be appropriate, I supposed.
click here

New victim to the list. My 8RDA+ got heavy wound: Dimm1 isn't working anymore! Just C1 and "peep . . peep . . peep . ." Luckily my Corsair didn't take any damage.
It took place when I was driving Pifast to test my new 2100+ and it said *snap*, machine booted and stopped at C1. Both Diim2 and 3 are still working fine, and performance is as good as it was before when tested the performance between one and two memory channels.
Well this piece was very early sample from review purpose and it didn't perform well anyway. It was beaten down still when we compared it to another, newer, 8RDA+. I was runnig at 218:2400MHz and 3-2-2-2.0, and still lost 0,5s in Pifast against 180:2300 5-2-2-2.0!

Next target is a brand new Soltek SL-75FRN-L, not because 8RDA isn't good, but it's hard to get one here in Finland. Though there was only one piece on Soltek either, but got it :D
And if Soltek turns out to be a sloppy one, then I'm surely back to 8RDA. ;)

KS1,

I've got some spare time and i'm really considering of replacing the burnt out chip myself. Where did you find the spec sheet? I can only find data on the IRU7313 chip. :s

If the burnt out chip is actually 2 mosfets in one, could you be so kind to give me the specs of the 2 mosfets? :)

Before proceeding, I think you'd better check if other components are not damaged either.
I think you might do this by using 10 normal A size (biggest) 1.5V batteries in pararell or if you have a power adapter that can output 1.5-2.0V DC at 5-10AMPS.
Jump the (+) wire to the output pin of MOSFET and (-) to GND.
Then switch the PC on. If nothing else is broken, a m/b should boot.

Buying 10 A size batteries just for testing is pretty expensive. :s

I'd like to give it a shot anyway, it didn't kill my cpu or ram and i'm not sure whether it blew my AGP card or not. I've got a cheap, old AGP card to spare, so i'm willing to take the risk. :)

Wow why don't you just RMA the board to Epox directly??

I tried to RMA it to the store where i bought it, no luck. I didn't get warranty.

It costed me $20 and 4 weeks, i've lost enough cash on this mobo...

By the way, I live in Europe. It's easier to win the lottery than get something succesfully RMA'ed over here... :'(

Anyone lost some SB or NB Features?
Think I lost my first IDE Channel.

Another alternative is to power NB from Vcore. Set Vcore to 1.50-1.65V. Jump the wire from CPU-pin Vcore to NB MOSFET output pin.

Just to see if it boots (anything on the screen at all or Port80 LED circling through boot process). If it works, you may want to leave it like that but Vnb will be tied to Vcore.

That'd be a good solution if it works. :)

Eh, i can't seem to figure out what the vcore pin is.

I found out a local electronic shop sells those IRF Mosfets! But not the particular one on the 8rda+ :/

Does Vds (IRF7313: 30V) AND Id (IRF7313: 6.5A) have to be exactly the same?

Is it ok to replace it with two 50V/14A mosfets?

You should find which pin is Vcore by looking at AMD CPU datasheet. It's easier to solder from a pin of M/B socket to an output inductor coil of Vdd.

Anyway, this is an extraction from IRU datasheet which outlines a criteria for selecting MOSFETs. I think the spec you have exceeds Vdss and Id criteria. It will be one of the most challenging soldering work since it does not come in 8-pin package.

I found someone with a dead 8rda+, and unsoldered his chip that i fried on my board.

I dunno how i managed to succesfully replace my dead chip, but it worked!! :banana:

My AGP port seems to be dead (could have figured that one out because it killed my ti4200), but a PCI VGA card works fine. :)

Left: voltmodded chipset voltage regulator (you'd think i'd learn out of my mistakes and don't voltmod it again? ;) Oh well, my soldering iron was hot, so why not...)
Right: fixed mosfet chippie

And it all works! :toast:

Currently burning in my XP1800+ JIUHB at 11*200mhz. This is going to be a fine folding machine.

Thanks all for helping me fix my board! (and screw you epos for letting me be a guinea pig ;) )

what a relieve!
congrats!

For AGP, have you try a 8x card (AGP3.0)?

No, only a 4x (ATI 8500).

I've got a R9500 (8x) card, but it's equiped with a pelt & h²o. I don't really feel like disassembling the whole thing. :)

Why would you think an 8x AGP card would work?

it uses a different volt.
maybe!

Dude, i don't know where you get all these brilliant idea's, but it works perfectly with my R9500 8x AGP card. Yey!

Thank you!!

just in this case, i think that m/b uses another set of circuit to make other volt.

Note:

1. before doing other mod, pls read my thread here
http://www.xtremesystems.org/forums/...threadid=10811

The carbon pot that you are going to use has +/- 20% tolerance level which is not good for a sensitive circuit.

2. Pls get a digital multimeter. It's more accurate.

Nice work Rich, not forgeting some good idea's from KS1:thumbsup: . With guy's vmodding boards and more recently changing mosfets and caps etc, I wonderer how far off we are from DIY motherboards?:slobber:

KS1, i switched the inaccurate pot with a fixed resistor. 1% tolerance and no chance to accidentaly overvolt. :)

success!

Cool, I found this post again. Anyway, its me again. The same exact chip that u fried on the 8RDA+, well, happened to me to. Im wondering what caused this?! What PSU did u use? You just slowly tuned your vdd and windows froze? And you lowered your vdd?! Weird... Mine fried after I tried another PSU which was an Aopen 250w.... It would get to BIOS, but would freeze after memory testing. I rebooted and same thing, then I rebooted and went in bios - no go. Finally, the chip burst into flames. Never had any probs with my Vantec 520w.... This is important to me: Did you damage your RAM after your mobo fried? Or any other component?! Im still sooo worried about my cpu, HDs, RAM, RAID card... My 4600 survived, yay. But you.... You repaired your 8rda by replacing the fried chip... You're good.... Yes you are. You're good, damnit.

I was going to overclock, so i slowly turned my pot.
mbm5 reported 2.04v, so i turn it back and it said 1.94v, i was aiming for 1.90v, so i turned it a little lower but windows froze.

Rebooting didn't help (motherboard turn itself of immediatly) so I unplugged the grounding of the mod (i didn't solder it on pin 4, but connected it to a fan connector grounding). Rebooted again and the chip right next started to glow... f*ck.

It killed my vidcard as well!!!!! I've yet have to test my friggin' expensive ram (2* Corsair XMS 3200) and CPU (XP2400+). I hope they still work...

By the way, my northbridge was watercooled.

Damnit. :'(

Dude! :eek: I think I got it! I think I know how our chips fried!! You said you took out the ground off your vdd mod... Maybe then the VR still gave it 1.9v+ with no ground protection and fried it?! And, when I tried the sh*tty 250w PSU..... I dont think it featured any over-voltage, power correction, etc, etc protections! Or simply couldnt supply enuff power stable and my 5v rail spiked causing my vdd to sky rocket or something?! Just.... WOW.... :slobber:

Hi

maybe a little late but i killed my 8rda+ too the same way u did.
that chip next to the vdd one just cought smoke and was all bright !

i rma it and im still waiting (4-5 weeks now).
I used a crapy 1K pot, no more pot for me only fixed res.

say, r u sure its ok to give ground from another place, like u did with the fan ground ?

BTW: im happey 4 u that u fixed that mobo man ! great job !
i thought to do that too but had no chip for that.

wierd guys,I have my vdd in my epox all the way up to 2.4 with nothing happening, maybe it is because I have pelted the NB but I doubt it.

omg u are sooo lucky to have fixed it.

mmmm lucky save :banana3:

Hehe,

Well done with the fix :D :D
