Help with 4gb XP-2 6400 996580?!?

[Narciuss]

Could use some help with it, as im new to overclocking. Any help would be great!!! Im trying to make it as fast as possible.

Specs:

Vista 64bit
Abit Fatal1ty AN9 32x Mobo
AMD Athlon 64 x2 6400+ <-- trying to overclock also having trouble...
Nvidia 8600gt 256mb
Muskin 4gb DDR2 XP2-6400
OCZ 1000 Watt PSU
Galaxy 2 Watercooling Kit

OK to overclock these all you have to do is increase your HTT and manually set the timings to their rated spec and voltage. You will most-likely hit a wall around 830-860MHz with 4-4-4 timings. At that point change it to 5-5-5 and you should be able to scale much further. I think you'll be able to hit 1000MHz which would be 250MHz HTT. Overclocking can be very tricky so I suggest you search for an AM2 overclocking guide that will help you keep all the other voltages and multipliers at good values. Here's one I found real quick:

I have been messing with my computer for the past 10 hours or so and im not sure if im doing anything right but here is what my cpuz says:

Do you think i could get more out of it?

Its looking good, try not to increase voltage too much, they might yield better without the voltage.

Voltage? U reading my Core Voltage im not sure if that is actually correct on cpuz because on abit uGuru my core voltage is reading at 1.57.

1.856 is unlikely, your temperatures would be extremely high. I would download coretemp to check cpu core temperatures. If 46-60 it pretty low even with an overclock. While running prime95 25.3 or newer.

You can get 70C + for 1.8 cpu voltage with air cooling.

Temps HA i laugh at temps! My cpu idles at 20-25C and under full load it is around 30-34C, some of it depends on my house temp. Also with the Cool n Quiet mode on it idles at 17C

I have ran Prime95 and it does fine till it gets to the second test and it fails. Im not sure what i should do, raise the volts?

Here is my current volt settings:

CPU Core - 1.5
DDR2 - 2.05
HTT - 1.3
NB - 1.3
SB - 1.55
PCIE - 1.25

I would run memtest86 first, to see if its the memory or the cpu causing the errors.

[Narciuss]

Well i would run memtest86 3.3 but it is not compatible with Vista 64bit.

Its a bootable cd. You burn it to a cd, then run when starting the pc.

[Narciuss]

Ehh ok so i burnd it on a cd, set my bios to boot from cd yet it still loads windows...

Hmm I don't know why, lower cpu divider to bring your cpu to default speeds even with the fsb increase. Run hci memtest for windows. Each copy with 800MB, running 4.

If that shows the memory is stable, then your cpu was why prime95 was failing. I would try an increase in voltage if this is the case.

Well i cant lower my cpu to default speeds with the fsb up to 250 because it is very unstable. So i just ran the HCI memtest for window 4 copys running at 800mb each. Ran fine no errors, nothing. Ran it till 120%.

Im pretty sure its not my memory its gotta be my CPU. Should i resort to raising the volts again?

CPU did get the hottest iv seen with that tho 38-39C, turned the fan up a bit and it went down.

Edit: Ah read the last part of you last post headn to do it now...

39C is very low for load temperatures, prime95 25.3 + should produce far more heat.

If you make 300% with hci memtest, its gotta be the cpu causing prime95 to fail, so I would either lower the cpu speed or increase the cpu voltage.

Ok so i raised my cpu voltage to 1.55 it runs at 1.63. Yea it increased my temps to 41C. Hope you know i do have a watercooln kit...

Prime95 is still running passn test still...

I think its all good now...
