Opt 144 OC WOW! However.....

LRTom · 6 Mar 2006 at 12:47

I've got my Opteron 144 running stable at 3.006Mhz! (16Hrs Prime95, plus stable through 3DMark, CrystalMark etc)

However, I have recently install a 7800GT which I'm 99% sure is the reason for some random crashing. The PC will freeze under varying conditions; Idle through to full load in a game.

My initial though was unstable PSU? It's a Jeantech 500W.Or possible board voltage unstable?

I'm running:

Opteron 144 @ 3.006Mhz
7800 GT OC to 450/1.16
2GB Standard PC3200
Asus A8N32-SLi

However, at Idle all voltages are stable and yet it still freezes up?

Any input/comments - Thanks!

What do the voltages do when you're running Prime or 3DMark. My bet is your PSU is dropping the rails when under significant load.

Mr Mister · 6 Mar 2006 at 13:21

what voltage you needing for 3gig?

Jimbo Mahoney · 6 Mar 2006 at 13:22

Whats the current on each rail?

(ie how many amps does the PSU say it can do on 12v, 5v and 3.3v).

I have got a Jeanteck 500w psu that I used on an old rig and the amps is only 14 on the 12v line, if yours is the same psu, thats a little low for the rig you listed.

I haven't checked the voltages when under load, only at idle.

I'm running CPU at 1.52 V, am going to try lower volts tonight.

Will check PSU specs tonight, 12V is reading 12.1V, 5V is reading 5V and 3.3V is reading 3.34V but this is as I say all at idle.

So the general thought is voltages?

Cheers guys

Check the white sticker on the side of psu, your 12v amps may be low. If I was having a guess, thats what I would say the problem is, as the actual voltages were not too bad on mine.

Is the graphics card made by XFX by any chance?

If It was ... what would that matter... just out of curiosity

mattio1980 · 7 Mar 2006 at 22:35

def sounds like psu to me not enough power

The power is fine its just the amps on the 12v line is a little low

I am running my setup (see sig) on a 460w Akasa .. 2x DVD burners...4x 80mm LED fans..TV card.. Audigy 2 soundcard ect... and the rest no problems

Get shot of that PSU. The psu is definatly not an area where to save money on. If that gets too overloaded and goes then the rest of your hardware might just end up going with it.

I will suggest to get a Tagan U22 580W psu. These are great for single and SLI / CF use. Over 35A on the 12v line. Or when spilt into 2 12v lines, you get 20A on each.

Have you got a volt meter? Try to measure the actual volts on the 12v line by reading from a spare molex connector when the rig is running.

Anyways, very nice overclock

Whats the stepping / week of your 144 ?

Dreadi · 8 Mar 2006 at 09:54

whats your stepping

LRTom · 9 Mar 2006 at 16:38

My stepping CAB2E 6020 ....... Didn't write it own :S

I'm deffinitly getting a new PSU, though there's been no freezing up in the last few days.

Are there any programs that can record voltages over a time? I.e. while i'm playing a game set it recording to give me a graph over a set period?

Cheers

you must meant 0602 cus 0620 is a future CPU

for voltage reading, dont trust any software, get an DMM

LRTom · 10 Mar 2006 at 14:41

0602 it is then!

I'll get one from work on monday and have good play around

Bennah · 10 Mar 2006 at 14:44

Any news on which psu you are going to buy ?

4Qman · 10 Mar 2006 at 14:53

Looks like ill be having a new Opty on order.

Bennah · 10 Mar 2006 at 14:59

The new ones seem to be very good atm.

Forgot to mention, LR Tom, did you get your Opty from OcUK ?

LRTom · 11 Mar 2006 at 15:19

Nah got it from Eclipse, work just down the road so easy to pop into. Got OEM model.

Not too sure on PSU, not too sure what to go for. Dont want to spend too much but know very little about who's good/bad etc. Any advice?
