cpu speed variation on the desktop?

[pik-ard v1.1]

ive noticed, that when i have cpu-z open, and sandra open, if i close sandra, my cpu-z reading goes up by about 1-2fsb/10-22mhz overall, for about a second or two.

my cpu was set at 138x11 = 1518mhz.

thats with cpu-z open, when i open up sandra, it drops to 1516mhz.

when i close sandra, ive gotten a jump as big as to 1543mhz. :eek:

now, im wondering, for just a cpu-z stable overclock, can i really claim that 1543mhz as my max OC, or just the 1518mhz that it will boot at?

before sandra: 1518mhz (http://members.lycos.co.uk/pikardv1/hpbimg/cpuz1518.PNG)

with sandra opened: 1516mhz (http://members.lycos.co.uk/pikardv1/hpbimg/cpuz1516.PNG), but... sandra reads as 1518mhz, very odd... :confused:

split seconds jump after: 1543mhz (http://members.lycos.co.uk/pikardv1/hpbimg/cpuz1543.PNG)

all this at less then 43C* on a t-bird 1200 :D

hot chip my arse... :rolleyes:


and no, this isnt at all stable... just stable enough to muck around in windows for a bit, not running any stress tests/benchmarks. ;)


*unless ofcourse my motherboard sensor detects temps a bit lower then they really are... which is ofcourse possible...

p.s. my goal was 1.6ghz for this chip... doesnt looks like thats gonna happen... :( all this /\ is on max voltage (set at 1.85v, overvolts to 1.93v) so i have no room for more voltage... :(

You think that 43C is hot my duron is running at 100C and up and on stock, sorry if i didnt answer anything.

[pik-ard v1.1]

no, i think the 43C is cool for max OC idle temps. ;)

100C? boiling temps... :P cook some eggs on that chip. ;)

with h20 you should be able to run 2v+ and get it to 1.6 easily

[pik-ard v1.1]

mobo goes up to 1.85v max. :(

and if i was gonna go out and spend that much money (h2o + mobo + ram), i might as well just go and build a new rig. and i have only about $300 in my pocket right now, so thats out of the question as of now. ;)

Lol when i try to touch the heatsink i like burn my finger lol

[pik-ard v1.1]

but, what does everyone think...

can i coult that 1543mhz as my top OC, just because it jumped there for a second, or just the 1518mhz, becaust thats what it booted at?

[saaya]

it has to do with how the proggies read the clockspeed, the clockspeed doesnt really go up if you ask me, it just looks like it.

you dont need a new mobo for 2v+ just mod yours, and watercooling isnt that expensive . d-tek block 25$ pump 25$ rad 25$ hoses etc 25$

[pik-ard v1.1]

yea... but thats $100 less towards a better system. ;)

eventually, i want to get one of the better clocking bartons, or even a a64 if i can get that much money togeather before summer. :P


i mean... no matter what i do with what i have now... im not breaking any records...

[saaya]

you wont break any records with your new system either unless you get a dual opteron 2.4ghz system and a r420 or nv40 with a dual cascade to keep both cpus at -100°C under load and a prommie for the gpu... ;)

i think your right though, you should rather get a new cpu and maybe a new cheap nf2 board as well. shuttle ultra400 nf2 is only ~50$ or so and when you mod it its a really nice board.
