View Full Version : Wattage question

I ordered a 2500+M this morning... now heres what im wondering...
to get my 1700+ cpu up to 2.0ghz... i have to run up 2.04v which really isn't a problem... my heatsink is handling it really well (53C)... now heres what im wondering...
ok... when my 1700+ is at 2.0ghz it's using up 106W... according to sandra 04... and it's still stable... so im asuming theres enough wattage in my psu for ocing a little bit more
ok right now im running 1.85ghz... 1.8v which is a little high just so it's stable... i should run this 1.75v anywho... it says im using up 76W
this is the same speed of the 2500+... that runs this speed at 45W... so i should have a little bit of headroom for ocing the 2500+ right...
since it runs this speed with alot less wattage... i assume that i should be able to oc alot higher... until it starts to go up alittle bit higher than 106W on my psu... then probably cause me some problems when my poor Antec Smart Power 300W psu cant take it lol any thoughts... i plan on upgrading the psu eventually... but i think im gonna give it a run for it's money
is there any way to tell how much wattage my PSU is currently using?
like on adverage how much do cd drives and fans take up... cause i'm betting i'll have to add this all up

2.04v to get a 1700 to 2ghz?
Those darn 'A' cores. :(
AMD has improved the core structure significantly since. ... a lot less heat @ same speeds.
The 2500m you have now will be pleasant surprise I'd bet. Not unusal
for them to break 2.6ghz in an NF7 with proper cooling.
Look here to see what you component requirements are:

It is impossible to measure wattage through any current motherboard, Sandra is only making a weird inaccurate estimation.

any estimation on what this thing could really be running...
when i run 2.0ghz... normally it runs fine folding at home and doing all my background apps listening to music... you know the deal... anyways... if i try and copy a cd... or access my DVD+RW drive to copy data... i always get a sort of ticking noise thru my speakers well my mp3 screws up and doesn't play correctly... and with my cpu at 1.85ghz it doesn't do that anymore it's only when it's at 2.0ghz... so im thinking im getting really close to the limits of my psu...
hopefully my psu will give me enough power to get a good OC out of the 2500+
the heatsink is down for 2.04v lol :D
should have a 80mm tornado sooner or later
this antec is great... i modded the fan inside to run full 12v and i'll probably mod the 3.3v rail to juice up these rams or my KHX3000 when i get them
my 12v rail is a little low 11.73v... but all the others are nice and high.. and stable at load

well right now it's at 13.5x185mhz... 2225 on my PC2700 memory...
and thats as far as it'll go... using up only 1.8v... and 38C load...
powersupply just isn't up for more... so im gonna pick up a powerstream :D

i dont think your psu is limiting you... get a multimeter and meassure the rails of your psu and maybe on your board in idle and under load, under the max oc and at a lower oc. a multimeter only costs you 10-15$ and will be very usefull in future :)

the problem is my multimeter is analog LOL...
the closest volts i can monitor is 50v... and you just cant see it fluctuating...
now in abit eq... if i look at it normally 12v line is 11.73, and 5v is 4.97
when i go load... 12v drops to 11.61v and 5v is at 4.97v still
it's fulcuating real bad when i refresh it it's always changing...
before it would stay at 11.73v no matter what
and this is only an Antec Smart Power 300W... it's not like i have a true 480W
i've definetly met the limits of my psu...
think it could power a 40x40mm TEC?

i dont know how good/bad your psu is, but afaik antec makes quite good psus.
i have a fsp fortron 350W psu and its not really limiting me to get my mobile xp 2400 to 2.6ghz :)
get a decent multimeter, as i said, you wont regret it. its a nice investment ;)

Over here you can get a cheap (louzy) multimeter for about 6-10€ so it's not much of a investment.
What I would like to ask: that site for calculating your wattage, it seems rather impossible to get above 300-350W so is this a reliable site to check? To bad you can't choose oc-options on that site :p

yeah im going to pick one up... since this analog is only good really for measuring -5v lol... you can see it fulucuate... but my 5v line is stable
more and more im thinking it's this chip...
but i dont understand how it could need an extra .1v in order to boot into windows at 2.5ghz and .2v to run stable
i can get to the boot screen at 1.775v... but to be 100% stable it needs 1.975v.... like damn
thats why im thinking it's the PSU...
i powered up everything else in my rig with a extra 250W psu... and i got to windows at 2.6ghz... with 2.2v... but it wasn't stable to load anything at all

i bet its the temps... bartons are very sensitive to temps and get unstable or crash right sway when they reach a certain temps. for me it has always been around 40C
CrazyXP1700
10-02-2004, 02:44 PM
yeah im starting to think that now... not like my 1700+ that ran real nice at 55C 2.0v LOL
my idle temp now is 36c and load is 47C my ambient temp is 21C...
and right now im running 2.0v
my onboard probe is touching the back of my cpu so it should be as inacurate as it can get
every once in a while i'll start getting IE errors... driving me nuts
i think im gonna slap a TEC on it and let it rip... i dont know i've got some stuff to try out first
im hopefully going to pick up a tornado soon... probably before a PSU
i may duct my 90mm fan down to 80mm tonight... to get all the air flowing thru the heatsink... see what else i can do...
running sandras burn in wizard and watching my temps... i get IE errors when it reaches 46-47C
but the cpu runs fine... it doesn't crash or anything it just keeps on chugging

hmmm get a decent heatsink man... its really worth it...

see, there are cheap yet good heatsinks that beat your cooler by a lot, def worth it!

The MCX462+ is a good heatsink, but there have been some better chunks o' metal released since then.
http://www.thermalright.com/
Check out the SP-97. It looks like it will fit your NF7 as well. Should be really cool with a tornado.
Review with a 2500+ (31-33c load in this one)

yeah... the MCX462+ is lacking a little bit nowadays... it still performs great and i only paid $25 shipped for it from a good friend so i cant complain about it's performance at all...
see what i can get a SP-97 for... and when...
but why would i have to be running all of this voltage just to make 2.5ghz stable...
also gotta wait for AS5 to settle... that might help a little... and a mad CPU burn in too
saaya
10-03-2004, 07:50 AM
cpu burn in... neh not really. and letting as5 settle... wont really change a thing dude, at least not enough to get you a higher oc...
check the vcore on the mosfets of your board and make sure its stable, if not then you know why the extra vcore doesnt help much..
CrazyXP1700
10-03-2004, 07:53 AM
right now im just looking for IE to be stable at 2.5ghz...
i mean i can run 3dmark just fine... WTF is IE and IM programs crashing
http://service.futuremark.com/compare?2k1=8153963
hopefully with the burn in and the AS5 settling it'll just be more stable...
it ran stable vcore of 2.04v with my 1700+ it did not fluctuate at all... nothing on the mobo has changed... just replaced the cpu...
im sure it's a wattage issue... and a cpu heat issue since i have to run soo many volts because it's now flucuating more than ever
the only thing i can think of is just this 300W PSU... i mean come on... who trys to OC to 2.5ghz with a 300W antec...

it sounds like your memory can't take it over a long period. Can you run memtest overnight without errors?
CrazyXP1700
10-03-2004, 08:14 AM
well i did memtest when my cpu was at 2.0ghz... im still running the same FSB and timings and voltage... all i've done was updated my bios and changed all the settings back... think that could have affected it at all?

You could just buy a FSP 530 and be done with it for like 75$.
jjcom
10-03-2004, 08:41 AM
yeah it could have. Maybe you missed something. Plus you really need to check your Vcore with the Barton. if you have to give it 2.2v to get to 2.6 than something doesn't seem right. I need 1.75v to be stable at 2.4ghz and you've got a mobile. You could try the processor in a different board and see what happens.
http://www.newegg.com/app/ViewProductDesc.asp?description=35-106-042&depa=1
heres the heatsink I've got. Its pretty good. In my case its very hard to install on my MB, but that could just have to do with the stuff near my socket. You might want to consider smothing it tho.

wont happen dude... wont happen.... :(
zeah, sounds like your psu is limting you... but again, get a multimeter to make sure its the psu :P

In my case, allowing my Artic Silver to burn in did allow be to overclock higher.
CrazyXP1700
10-03-2004, 11:19 AM
im sure it's this antec... i mean i can get to the boot screen at 1.775v... 2.5ghz... it's just to make it stable i have to run a ton of volts...
mobo ran a ton of volts before... no problem... but now were dealing with a cpu that wants a little more wattage and it's just not there... atleast thats what i think it may be...
my rails could be stable... but if theres no wattage.. wont it still fock up? :confused:

if there are enough watts the rails drop or fluctuate. if the rails are stable and within the specs the watts are fine...

what speed gain are we talking about here? before it was stable at? and after? the temps dropped how much?
jjcom
10-03-2004, 02:22 PM
My temps dropped about 3 degrees and allowed for me to go to 2.4ghz stable instead of just a screen shot.
saaya
10-03-2004, 03:13 PM
3C? wow... thats a lot... weird... never heard of that before.
you mean before you could just take a screenshot at 2.4 and with prime it would crash inmediatly and after the arctic silver "settled" you could get it 100% stable for hours of prime?

What type of AS was it?
jjcom
10-03-2004, 03:21 PM
yep. I saw a large temp drop and my computer ran stable. I would idle like at 44 degress and now I idle around 41. in. load went down from around 53 to 51.

yeah... im doubting a 300W would be reliable for any higher than 2.5ghz with all my stuff...
IE has finally stopped crashing (sort of) after Sandra's CPU burn in's all night... now IE only errors while sandra's running the CPU at 100%... and my doing regular stuff temp has dropped 3C normally it was 43c now it's at 40c... if i let it idle it'll probably go down a little more... who knows...
i have AS5 in there... and that stuff is known for dropping temps a few degrees when it settles in
but it looks like soon enough IE will be stable even at load... which would be nice...
and i definetly think it's my powerbox... but i might upgrade my cooling anyway
