Hiccup ?

Sorry I dont understand what you mean by this.

It sounds like your PSU isnt able to run stable when overclocking this is a common problem with the 8kha+.

What PSU do you have ?

And what are the voltages of the 5v and 3.3v lines at load.
(use motherboard monitor 5 from www.aoafiles.com to find out)

4.84 isnt too bad.

It might be your problem but non necicaraly.

WHat memory are you running ?
How are your timings and voltage set.

Whats the spec of the rest of your system ?

I still dont understand what you mean by hiccup ?

Iam running an 1900+ at 1.79GHz 1.87V and i have never experienced any hiccup mode.It runs 24/7 RC5-64 blocks or folding@home.
Mine 5V is at 4.88-4.95 under full load.

I dont see how you would trip the overcurrent protection when using 1.85v.

ive seen many people running over 1700mhz 1.85v with no problems.

people have only reported problems with the over current at around the 2v mark.

I suspect your instability is either a PSU, memory or CPU problem.

I'm able to run at max 2.2vcore using just the normal 220k pin 2 mod with my XP1700.

With an Athlon Tbird even 2volts was too much, i'm guessing XP's draw far less current.

btw at 2.2vcore my 5volt line goes to 4.95volts running Prime 95, the only issue at this voltage is temps. Aircooling just does not cool enough so i prefer around 2volts max.

Th hiccup mode is a feature of the 8kha+ voltage regulator
and kicks in when the over current protection limit is passed

and the limit in mine is ver very , very LOW

dazzlew you 8kha+ is fine mine isnĀ“t
Now I understand.

How can you be so sure its the over-currnet protection ?

Ive had similar symptoms from a variety of other problems when overclocking.

never had a problem...

i have a xp2000+ at 1807 (172x10.5) and my +5 drops to a frightening 4.7 volts at load and around 4.76-8 at idle. i know the PSU is terrible.

i have never had any problems with the over current protection that you speak of.

its totally stable at around 104 F full load and 90 F at idle.

am i of any danger at running at such a low +5?

Since its stable probably you dont are in danger but 4.7V is low and probably you should invest to a new PSU.
