Well I guess you were right. Been running all day now with no problems. Must have been that Sparkle PSU. Still seems pretty odd though. But no matter, I'm back running at 203x13 at 1.925v so I'm happy.

can I cut that track with a simple cutter and a magnifier?
Yes, it should be a very sharp razor knife or blade. Here in the states we have a popular brand of razor knife called "X-ACTO". It's the kind of sharp pen-knife that you would use to cut parts on plastic model airplanes or cars.
COOL! :banana:Quote:

Good job!

Could ya help me w/ my prob?
Don't really know what could be my prob.
I have a 1800+ T-Bred w/ an RIRDA stepping, only 300wattsPSU, 256mb 2700 mem, Ti200, 4 case fans, 2 7200rpm HDDs, Modem, TV tuner.
1)Is it the PSU? My friend only has a 300 watts PSU(not exact rating), 8k3a board but do wonders on overclocking even though he has numerous parts in his PC (3pcs SCSI, 1 IDE, Ti4400, 6 case fans,etc.).
2)or Is it the Athlon T-Bred stepping? Now I'm running 1750 real clock @ 1.60 Vcore.
3)or We all have same prob? But mine's worse I run it @ 1833 real clk 11x166 @ 1.7 Vcore then it restarts or doesn't load OS. Is it because its hotter here in ASIA? Or my Vcore's too low, etc?
PS: already put small aluminum plates @ Mosfets & IRU3055 chip & my last try @ 1833 real clock is the same, could not load OS.
I would greatly benefit from anyone who cud help.

And thanks in advance!
Hi j813,
So the problem is "it restarts or doesn't load OS"?
I will say that MOST 300W power supplies are not able to provide enough power for a high performance computer these days. Some will, but most won't. With everything you have in your system, you should have a power supply rated for at least 400W.
I use a Sparkle 400W supply. It's a very solid, popular, AMD approved power supply. Antec also makes a good PS.
I'm very fresh user of this mobo, and I've been busting myself with failed attemps in overclocking past my old 8k3a levels. The max stable with this mobo was 2.025 and I could bench at about 2.8G chilled water cooled. Then I just notice this thread to find out exactly my problems here :)
I'm doing the mod this weekend, thanks
I noticed that the Mosfets is laying down.
Normally transitors that are hot are supposed to be standing & bolted to an aluminum plate, just like in the Amplifiers, PSUs, etc.
Would there be a way to make this transistors stand & have plates on them?
You know I had that same question. They used to stand them up in the breeze with a heatsink. They probably don't because of cost and because they could get knocked off if they were sticking up in the air. Also because they work fine at stock speeds.
It might be a cool mod to unsolder all of them and mount them on a single aluminum block and then wire them to the mobo. Sounds too much like work though. ;)
i think i have the same issue now
at first i could run 2.2volt on the cpu :(
so Removing r678 is 100% working for 24h on 24 2.2volt?
Stupid question, but how do you remove the resistor with a soldering iron like somebody said? I haven't done much soldering, but I do have a good small one that I used to do my vdd mod.
Can someone just give me a walkthrough on how to remove the resistor with soldering iron.
Much appreciated. I apologize for my newbiness
All you need to do is touch the resistor for a couple of seconds and it will probably stick to the end of the soldering iron. The resistor is only being held in place on the board by a very small amount of solder. It will come loose very quickly with a little heat.
I still prefer cutting the trace, much easier to undo. Once you unsolder that resistor, you'll either lose it or you'll never get it back on the board again if you wanted to.
Are there any update on these problem?
Any other links I can go to?
morphling1 could you help me with your hardware add-ins?
Thanks a lot to all
Man I need help. I did this mod as described, and now everytime I exit bios the alarm I intended to get rid of goes off!! It PC Health Status says my vcore is 1.20 !!!! What gives? What did I do wrong and is there any way to fix it?
Lower the FSB back to normal and the vcore should reset itself.
bh,
If you need to undo the mod for some reason, you can solder a small length of wire from pin16 to R678 (the side closest to the VR chip). That will effectively jumper the cut trace and restore the original circuit.
I've never seen anybody need to do that though. As TT said, try your BIOS settings or even reset CMOS and try again. Also, make sure you're running a current BIOS (3117 or better).
Spartacus, in my case removing R678 didn't help, I still get the same freezes in prime95 as before the mod in anything above 2.05V the freeze is instant. And the only thing I change is Vcore clocks stayed the same
The cooling isn't the problem btw.
Got any clues ?
I think I maybe cut a little to far past the holes or a little to deep. I have reset all back to default, cleared cmos, tryed upping the voltage but there is no response in PC Health Status, it stays at 1.20 no matter what vcore I set.. what are the conections to either side of #16? Is there a chance I botched it and cut one of those?
Also: I'm using 12/31 bios...I haven't cleard the cmos but I'll try it....I just did'nt think it would fix a prob like this, and I wasn't OC'ed at the time.
something is changed but the mod isn't 100% working to my 8RDA+
There is no reason to expect this mod would fix a freezing problem in Prime, that's not what it's for.Quote:

Sounds like you're pushing the CPU too hard.
now i'm cooling the mosfet with a 120mm Fan and prime is running from 16 minutes.. Vcore 2.15v
let's hope..
I've seen a lot of reports of this mod working as expected, and some reports that it didn't help but didn't hurt anything. Yours is the first I've seen with this symptom.Quote:

Solder a jumper from pin16 to R678 to undo the mod (like I said before). Flash to a current BIOS if you can (like I said before).

Great!
Cooling is definately important.
This is definetly mobo problem as I had same cpu at 2.1V on 8k3a running without problem.
Cpu has quite some room left because same thing happen if I unclock for 100 or more MHz, but from 2.05V on prime freezes instantly without any errors or similar. So definetly not cpu being unstable or ddr or unsufficent cooling on mosfets that voltage controler or anything else, all cooling is taken care off.
morphling,
You're overclocking the CPU by over 1Ghz though correct?
(Congrats on an awesome OC BTW!)
Minor differences in mobos become a big deal when you're pushing the hardware that hard. I don't think the Vcore power supply circuitry on the 8RDA+ matches the abilities of the 8K3A. Different boards, different designs. If you are convinced the CPU has more in it based on it's performance on other mobos, then I'd say you've reached the performance limits of the 8RDA+.
EPOX redesigned the Vcore supply on the 8RGA+, so that should tell you something. I see people getting very good numbers on the 8RGA+ and on the new Abit rev1.2 NFS7.
