I've just about had it with this current system. Some of you may know about my overclocking antics with my 2500 and epox 8rda3+ mobo. To sum it up, the experience was great with my 2100xp, it ran fine at 2200mhz/1.8v and VERY cool.

At the moment I have a 2500 barton and its been nothing but a pain since I got it about a week ago. When I first tested it with prime95 for 3 hours straight at 2295mhz/199mhzfsb with 1.64 volts it ran like a dream. Going up to 2434mhz on 1.76 volts running prime for 3 hours stable after running it at 2295mhz it was fine. Then later on I went for 2486 on 1.8v and thats where my problems started. It restarted the pc and left it in a state where the fans are still spinning but no other activity. I went back down to 2436mhz and it did the same thing after 10 seconds of prime! I went down to 2305mhz on 1.66v and it froze!

Temps arent the issue I dont think because it does it on lower volts/temps at about 47c load. Anyway I got it running fine again at 2305mhz on a whopping 1.76V! So I took out the case fans and the dodgy dvd drive thats been opening and shuting on its own lol and replaced the ide cable with the one that came with the board and I'm back at 2405mhz on 1.78v with 53C load using my 2,800rpm fan. Its been running prime for well over 40 minutes with out a problem so far but this is getting beyond a joke.

If I cant get the system stable at this speed, a speed that I know this cpu can do, then I'm getting an abit NF-7 S to replace this motherboard as I'm currently amazed at how it will run for hours stable on 1.64v and then need 1.76v later to run stable again!

It may be my PSU as its a Q-tec 550w thats only a few months old but I've been running at 2.1vcore/2.8mem on my 2100 with zero issues! Will get a new one if this keeps up before a mobo swop I think but this one is very confusing for me, who has been building systems for a few years now...

speed what kind of ram you got again? Try a new power supply first, perhaps a better brand 500, then if that's not the problem just return it :) It sounds like your power's problem.

I hate Computers! My P4 2.4C won't go above 3840mhz. My Sapphire 9800pro core/mem speed won't go above 490/790. I really hate computers!
 
It does seem like it, but my rails are fine. I'm starting to suspect the dvd-drive as it would open and freeze the system at random.

When I took it out, my cpu temps dropped 4C+ and the cpu rail is now a bit more stable. At 1.8v in bios it was going between 1.75-1.78, now its 1.76-1.79.

Im currently @ 2405mhz/ 201mhz fsb @ 1.78v with the 90mm fan and its almost as cool as with my 2 smartfans @ same speed/voltage.

I dont believe this, but I'm past the 2hr mark on prime95 again where as before it would freeze/reset unless I fed it 1.86V!!!!! Could a dodgy DVD drive cause power instabilities or other problems to cause an unstable overclock?

Oh and my memory is Twinmos pc3200 cas 2.5/2.7v memory (2x256mb). Currently running it at 201mhz cas 2/3/3/6 on 2.8v.

Well I'm still a newbie at overclocking so I've never heard of a DVD drive could limit overclockability.

I hate Computers! My P4 2.4C won't go above 3840mhz. My Sapphire 9800pro core/mem speed won't go above 490/790. I really hate computers!
 
Well it went 3 hours at prime95 no problems. Just done a virus scan of my drives too, they are clean. Fingers crossed it stays stable.

Hope you can get it stabled, I have a friend well recruit370 he got his barton 2500+ stable at 2475mhz(11x225) with Vcore at 1.775, He's using the A7N8X Ultra400 nForce2, 512 Kingston Value Samsung chip pc3200, and using Swiftech MCX462+ with 80mm Tornado, but his temps can get above 50C on load. Oh and also his vdimm at 2.8 running at 2.5-3-3-7

I'm pretty sure its the psu as it froze again at 2405mhz, after 10 minutes of prime. Heres the details of my psu

3v max = 20A
5v max = 35A
12v max = 15A

Heres a top brand spec:
Antec 480w
3v max = 30
5v max = 38
12v max = 22

No wonder I've been having stability problems LOL!

Bummer! Epox had always done so well with power regulation in the past.

OK, so they did like extra beefy power supplies.

I'd email Epox and find out if the issue is true. If so, perhaps they will mod your mobo for you or replace yours with a mod'd one.

I don't think the 8RDA+ had this problem. What are the supposed advantages of the 8RDA3+ ?

Hope they'll mod it for you speed

Most of the posts there are people with the 8RDA+ board and some people have the issue with my board. My board has official support for 200fsb and 3200xp and adjustable voltage for the chipset. Its suppost to be the overclockers dream, but so far it been a nightmare!

I will try a new PSU but it probably wont come until friday or monday. Ive settled for the antec 480w true blue PSU. Heres the specs compared to my current thats more like a 400w psu with high 3v rating. Amazing that I managed to run 2.1v at all on my 2100xp.

Mine:
3v 20a
5v 35a
12v 14a

480w antec:
3v 30a
5v 38a
12v 22a

Im 85% sure its the psu coz one of the fans stopped spinning inside it after making clunking noises LOL! I think it may be shutting down because the regulators are working too hard to keep the voltage stable, thats why my 12v lines are ok, but its unstable because theres just not enough constant juice being delivered.

ROFL this just gets better and better. I decided to rebuild my pc, took everything out, reinstalled the 900u and everything and got it running again and decided to run it at 2305mhz/1.68 volts until I get a new PSU but forgot to change the multiplier so it booted into windows @ 2405mhz but on 1.68V! I tried prime and it failed, so I upped the voltage a little to 1.73 and its gone over 30 minutes of prime95!! I dont know what to make of this pc lol. 😱

Hope that fixes it.

BTW, that DVDROM draw opening/closing thing. I've read about that several times. Although it can be a hack/trojan it's usually fluctuating voltage triggering it. I can't recall if it's 5 volt or 12 volt fluctuation that does it.

Also, about overclocking issue I have a very old EPOX mobo, 8KTA3PRO (which is partly why I know about high PSU demands), but I have a strange issue that may/may not be similar to yours.

For some reason, my 5 V rail drops with time. Not power on time but calendar time. If I freshen my ATX connection I get about 4.88 volts for my 5 volt rail. (This is not surprising. Older Enermax power supplies were notorious for running a little low). After about a week (16 x 7, not 24 x 7) the 5 V rail will be at about 4.80 V. After another week it will be at 4.70 V. After a third week my system will be noticibly unstable when gaming and I will have to refresh the ATX connection once again. The 5 V rail returns to 4.88 V, the system is again stable, and the cycle starts over again.

Weird, isn't it?

i beleive your powersupply is the issue...the 8rda+ takes its vcore from the 12v rail unlike most other boards...your current powersupply does not supply much to that rail...

The only bad thing about the 8rda+ is it needs a good powersupply...

This post doesnt have much if anything to do with your original post, but i wanted to ask you folks what you mean in regards to colour of the CPU? You say a "GREY" cpu is beter then a more "purplish" one in terms of OC and low voltage settings vs mhz ratio. Im not familiar with this colour coding and was curious if you could explain it to me? Thanks in advance.
 
not color coding...when a cpu core is made it is made on a large wafer of about 100 or more cores...

the ones closer to the center of the wafer have more pure silicon than those at the outside (hence better overclockers) anyhow...if you have a grey core that is a sign of more pure silicon


Proud owner of DOS 3.3 :smile:
 
And I have proof of this too. 2100 purple core = max 2300mhz on 1.92v. 1700 grey core = max 2389mhz on 1.9v
2500 ugly purple core = 2378mhz on 1.9v and finally my new 2500 nice grey colour is doing 2405mhz on 1.73v until my new PSU arrives :)

Well recruit has 2500+ purple core and he got 2475mhz at 1.8 vcore

Yeah and when I get my new psu, it should level out the voltage so give me stable overclocks. Remember when I said my mobo undervolts the cpu? Well I think its the psu thats doing that. But a setting in bios of 1.75 giving anywhere from 1.71 to 1.76 has just got to give instabilities. I did go over an hour at this setting (1.71 lowest vcore) at 2405 so if I can get it stable to 1.75v, it should give me upto 2450mhz + and maybe over 2500mhz on a stable 1.8v.

BTW ive settled on the 430w antec as the 480w is out of stock.

Also I seem to be getting poor overclocks from my 9700pro too. 355/320 is very low compared to others that get upto 9800pro speeds on stock cooling and a bit higher with better cooling. That takes power from the 12v line also, just like my hdisks and cdrom. I hope I can sort out my problem plus get a better overclock from the radeon, that would be super sweet!

Speed, you have connect3d 9700pro right?

Soz for the late reply, yeah its a connect-3d 9700pro with a much better cooling setup now though :). BTW my antec 480w should arrive tomorrow and hopefully (fingers crossed) will help me get back over 2400mhz 110% stable :)

EDIT: Decided to spend a bit more and get the 480 antec from another site just to be sure I have eliminated the psu as being a problem!
