OC of my athlon 1200C. final results

[lhgpoobaa]

Results are in for overclocking my system.
today i got the pesky thermal pad removed and two 80mm casefans installed.

note: indicated core voltage is some 0.05V higher than what i set in the bios.

testing done case closed, SETI@home for 100% processor usage. playing mp3's for easy ID of lockup. like playing musical chairs when the music stops its gone!

athlon 1200 C (i.d. unknown, i forgot to look when getting the HS removed, ah heck)
a7v133.
PC150 kingmax ram.
winfop 32-1 cooler.

8.0x150=1200 @ 1.65V (1.70V indicated) - very minorly unstable, locked up with overnite testing. will be useful for daytime hot summer day running.

8.0x150=1200 @ 1.70V (1.75V) - stable, 4 days @ 100%. 45C idle 50C full 28C mobo.

7.5x160=1200 @ 1.70V (1.75V) - blue screen after 20mins. reboots failed to load windows. tried CAS2 & 3, same result. HDD most likely at fault. doesnt like 40mhz PCI.

9.0x150=1350 @ 1.75V (1.80V) - random lockups 1 to 2 hours running time.

9.0x150=1350 @ 1.80V (1.85V) - stable for > 3 hours, no lockup. must test more. 50C idle 54C full 29C mobo.

10.0x150=1500 @ 1.85V (1.90V) - no bootup. tuned off real quick!

9.5x150=1425 @ 1.85V (1.90V) - lockup within 20mins.

9.5x148=1406 @ 1.85V (1.90V) - approx 45min-1hour till lockup. 52C idle 59C load 29C mobo.

10.0x140=1400 @ 1.85V (1.90V) - what its running at while i type this (with frequent saves!), opps. lockup after 1 hour. bummer.

CONCLUSIONS / QUESTIONS.
1. seems that 1400Mhz is my magical limit. looks like i dont have one of those special AXIA's then.
2. has anyone else run their system beyond 1.85V? mines set to 1.85 but it shows up as 1.90V.
3. i think on the whole 9.0x150=1350 is best for me. next ill try to push the FSB up 1 mhz at a time, find the true system bus limit.

4. anyone want to guess what stepping my core is?
cheers. this has been fun.

probably a avia, not as good as axia but still good for overclocking. Running 1.9vcore is fine, mine adds .6 and I run mine at 1.91, well used to. I am running 2.1vcore now. You might want to get a new heatsink fan config as that is plainly holding you back.

Well done,good to see someone post their success story in some detail. How much further are you willing to go?

~OMG IT nearly melted, lucky I had the extra fan *inside* ~

well getting up to two speed incraments above mine would be nice i.e. the 1400...
however i think
1350 @ 150fsb is better all round than 1400 @ 140fsb
1. higher fsb
2. lower core voltage.
3. 1350 @ 1.85 has been stable for 5 hours now. a decent indication of stability. an hour of that was Unreal tournament.

besides... its not quite stable at 1400... probably needs the voltage set to 1.90 (1.95V indicated in bios & MBM)
i dont know if i really want to do that.
the winfop32-1 IS a good heatsink...
sure i could get a volcano2, but its TOOOOO LOUD! (smallish room with case on desk beside monitor)
ive already stuck two 5" squares of sound absorbing materian on the inside of the sidepanel to get most of the processor fan noise!

and should i really be running at 1.95V???
i'll be wanting this pc to last at least a year you know! lol

i also still have to find the absolute limit for my FSB... apparntly its somewhere between 150 & 160. Lucky the crash due to a FSB overclock is different from a Mhz freeze. usually results in a bluescreen or reboot.
mmm. now 9.0x156 would be ideal

given what im trying to do, my poor little system is behaving really reasonably
a nice time vs mhz decay noticable i.e.
1400 = 1.5-2 hours
1406 = 1.5 hrs
1425 = 20 mins
1500 = 0


hmms. still have to OC my new videocard too. but that can come later

Hamster on Smack!
