Hi,

My overclock as stated in my sig has know recently become unstable...

Do you think its my PSU

I have a Antec NeoHE 500W Modular ATX2.0 PSU

Just happened randomly, no warning....its tries to restart but then blue screens giving me an "IRQ LESS OR EQUAL TO" error

All ideas and suggestions would be appreciated...

If you think it is my PSU please suggest a bang for buck replacement,

Thanks in advance

Cheers!
 
check the voltage rails with speedfan or other voltage monitoring software....the ones to check are in tollerance are the 3.3v, 5v & 12v rail.
 
vcore1 = 1.3v
vcore2 = 1.17v
+3.3v: 3.18v
+5v: 4.78v
+12v = 11.65v

-12v = -9.4v
-5v = -0.6v
+5v = 4.78v
Vbat = 3.06v

thats at stock

Nothing overclocked

Does this mean Im bordering max rails already? does it therefore confirm when overclocked my psu cannot handle it?

funniest thing being my system was stable for over 4 weeks...

please advise

thanks in advance
 
i reckon its your 5v rail, it looks a bit low tbh.

under load it would drop further i'd expect which could be causing the problems. I dont know why a 500w decent PSU would struggle to power that system though - maybe it has a fault?

Also just as a worth a try type thing you should make sure that your CPU cooler is free from dust as they can get (especially close finned performance coolers) completely caked/clogged in thick dust causing reduced airflow and increased temps.

I normally clean them up carefully witha small screwdriver...


...when the machine is off obviously :D
 
think Ive found the prob:

Basically I was running the RAM @ 1:1 which means my RAM was running at 530mhz which was causing the BSOD on overclocked settings...

However I just lowered the RAM divider to 2/3 = 176mhz per stick x 2 = 352mhz in total and it ran perfectly well

However thats really short of what the RAM can run at...

Which means either:

a) lower the cpu overclock so memory can run at 1:1
b) run everything at stock

Hmmmmm

Kinda confused at this stage

Ive just been playing oblivion for 30mins+ on overclock settings with RAM at 2/3 divider....no crashes or blue screens....

What am I doing wrong?
In order for my overclock to run at 270fsb (cpu) it means I cannot have my RAM running at 1:1 right?

So what do I do next?

Please advise..

Thanks

P.S. If I can run my memory close to 500mhz that with this overclock (270fsb cpu) Id be happy...

Appreciate all help and advise guys

Thank you
 
what is the multiplyer on the cpu? i run at 11x250 with a 166/200 divider fine. if you run at 270 then i reckon a 150/200 divider would be safe
