2500+ overclock temps

Just upgraded my processor to 2500+ and was dabbling in some overclocking, just interested in what others thought about temps.
System is

Antec TruePower 380Watt
Athlon XP 2500+ (11*190=2090mhz) (stock HSF)
Abit NF7-S v2.0
Kingmax pc3500 2 X 256meg (2.5 3 3 6)
Gforce4 ti4200

At stock its sits around 47-50*C upped the FSB to 190mhz and stability became flaky, only lasted about 15 mins in prime 95, so increased the Vcore to 1.725v and its now stable but the temp goes from around 48*C idle up to 58*C under load. I was keen to try and increase the vcore and try and push it all the way to 200mhz fsb but the temp is a little to close to 60*C for my liking. The chip is locked so multi change is not an option. What is considered acceptable temp for Barton chips?...... Ive always thought of 60*C as my thresh hold.
I am using stock HSF how much temp decrease would I expect if I moved to a quality third party cooler. Those with the actual temperature variations they experience and the cooling models they used would be much appreciated.

You need a diffrent heatsink and fan. I have never had luck with Athlon heatsinks so I startied using a $9.00 Speeze heatsink and fan. My stock 2500+ Barton core is only runnning at 34*C out of the box. I overclocked it to a 200 FSB Frequency and it only reached a temp of 43*C ( That was after 1 hour of rendering digital video = 100% use of processor)

I'm in the middle of an OC with a similar rig (see my sig). Currently my FSB is @192. Stock HS+F. Some questions:

1) What are you using to report vcore? The mobo undervolts. I have it set to 1.725, but MBM5 reports about 1.68, roughly same for SisSoft Sandra.

2. Same as above for temps

I believe your ambient/room temp will make a diff. I'm in the cold (Smoky Mtn, NC) with unheated room about 40F.

I noticed my temps moved up significantly when I made a vcore increase (mobo settings) from 1.7->1.725. MBM5 is now reporting 47-48c at full load (Prime95 torture test)

I understand AMD says something along the lines of 80c is max, HOWEVER, (and this is why I stopped by today, see my post), there is a diode temp and a socket temp. Diode temp being considered the more important/accurate. That is, the socket temp may be reporting too low.

BTW, as your ram is pc2700, are you trying to run FSB 200 with ram/cpu im synch? (much preferred for performance). Memtest86 will identify whether it's your cpu causing instability (thus requirering a vcore increase) or if it's ram (thus requirering Dram voltage increase)

Good Luck with ur OC

Watever HSF you are using is either junk or not put on right. If using a shim, remove the wrapping on it. Otherwise get a better one. That stock cooler was really meant to stick with the stock voltages since that fan on it only generate 18cfm AT THE MOST!!! May I suggest a Thermalright HSF solution for you high voltage needs.

Yeah I have also noticed that my voltage core seems to be reported around .25 volts under what I set it. I have used a few different programs including AbitEQ, Winbond and they all say around the same 1.7 when I have it set to 1.725. I also noticed quite a leap in temps from 1.7 to 1.725 vcore it hadnt really gone above 52*C with all my other test from 1.65v-1.7 vunder load and I increased the VCore by another .25 and suddenly it leaped up by 5 or 6*C.

As for ambient temps, it is the middle of summer in Australia where I am, and we have been getting consitent 35*C days of late which is obviously a contributing factor.

The ram I am using is not pc2700 it is pc 3500, and Im not having stability problems at the moment, its just the temp. I ran prime 95 for 10.5 hours last night with out error and have played C&C Generals, MOH, BF1942 to test gaming with out any problems.

Ok checked out the HSF available from my local dealer. Am looking to go copper and was looking at 2 from thermal take primarily although I am open to suggestions. The Thermal take Volacano 10+ pure copper as my budget option or the volcano 12 extreme is bit more spensive. There is around about $25 difference between the models. The volacano 12 comes with a fan adjustment control that slots onto the back of the case but am not overly interested in that. Just wanna know if the volcano 10 is up to the task and if not ill go for the volcano12........Waddaya Think???

Poncho, I'm shopping for a HSF too. I'm afraid in a few months (Summer) I'll have heat probs up here too.

I'm reading a lot mixed reveiws on the volcano. Right now ther Vantec Aeroflow looks good. The website reviews I read were all very highly positive, and head-to-head benchies showed the aeroflow beating the pants off a volcano 11+ (or11)

Did notice two negative reveiws from private individuals (among even more positive ones). One said the fan started whinning real loud after a couple months, otherwise it cooled great. IMHO, that's just a warranty issue-he should just rma. The other bad "personal" reveiw said no cooling improvement, but I don't recall if he said whether he was using stock before, also could be he didn't install properely.

Anyway, I put more stock into the more professional reveiws, especially the head2head benchie. You may want to check out the vantec aeroflow unit. If I see the reveiws I'll try to post back with a link.

BTW, here in the States the aeroflow can had about $23 (includes shipping)

2cd btw, the aeroflow (manufacturer's part # VA4-C7040) has a copper core with advanced fan and fin design. And the finish on the base of the HS looked very good, no need to lapp, better than most.

sorry to but into someone else post but I should have new pc3200 ram by this evening and am gonna overclock my xp2600. For HSF I have a spire falconrock II and heres the thing. In the bios (asus a7n8x) the temp is reported idle at 45 and under load at 50 degs BUT using either mbm5 or asusprobe (which came with mobo) it reports the temp 10 degs lower at any given time. So which temp do I trust??? If I trust the bios then my chip is already running hot and if I overclock its gonna get hotter and 50+ degrees aint good...

also does anyone know if the falconrock2 is ok to overclock with?

ummm....10deg lower at any given time? what do you mean?
If you're using WindowsXP, then it could be that this OS comes with a little program that keeps your CPU "really idle" when it is idle.
In bios, your cpu's temp is the temp you'll normally get when close to full load.
Try run some app such as SETI@home, Prime95, Super Pi and log down the results using MBM5. You'll probably notice that the temp is similar to your reading in bios.

A fine day!

Room temps matter a lot. My friends added on bedroom doesn't really have a good heatsource. The floor get's fairly cold and when i have my oc'ed 2500 there my temps under hours of gaming are only 35c.
In my house it's a different story, my computer is somewhat near a covered heater vent that i also shut off, and the room is fairly warm all the time.
If i hard shut down my computer and turn power supply off it stays about 34-35c, but as soon as it starts to heat up there isn't enough cool air in my room to keep it belowe 45c, it usually will stay around 46-49c. Which i'm not too concerned becuase when the summer comes that duct will be blowing really cold air.

Figured i'd do it too..reality my ass.

Wolfie, There's rwo different temps reported for the cpu. One is socket temp., the other being core temp. Socket temp, which is all my mobo reports, is said to be about 10c cooler than core temp (from inside chip). Now the AMD has the ability to report the core temp, some mobo's support, others don't (cuz it freaks people out, being that it's higher)

Could be your looking at both and that's why one is 10c higher than the other.

Ponch, That's exactly what my chip did. Shot up by 5-6c when I did the exact same increase in vcore. Didn't happen in the next jump though.

I just ordered a Vantec Aeroflow anyway, even if I don't go up any higher, I figure I'll need it this summer when the room temps climb.

btw, my chip really likes it at FSB 192, seems like some kinda of "sweet spot". It runs really snappy and is more stable than at 166. Every once in a while I'd lose my USB mouse even at 166. That pretty much stopped at 192 fsb, prolly cuz I'm using win98se though. It's considered a little buggy on the NF7-S

fair enough, got the ram clocked the xp2600 up to 2.26 so im well impressed, temp only went up by a coupla degs but its kinda cold here at the moment..... but still im well impressed :D

Just wee update..... havnt got around to getting new HSF yet as my usual suppliers are pretty limited in what they can offer other then thermaltake . I have now read a few bad reviews on their whole range mainly in regards to the noise factor so I am looking at a few other options. I did get new tube of artic silver so I could take off the standard thermal pad AMD supplies which I have heard so many bad things about. But alas did not see a single bit of difference in temp. As with my other cpus I Tinted the heatsink, and applied thin layer on the core of the cpu.......perhaps the much malinged AMD thermal pads arnt quite as bad as they are made out to be

Coyote let me know how your temps are affected when you get your vantec aeroflow if you could thnx!

Yeah,the temp of your systerm is really a bit high.After my old motherbroad Epox 8RDA+'s retirement,i bought Abit NF7-S,but i found it a bit strange,my CPU which could run@2100Mhz(175*12)on my old matherbroad couldn't reach 2100MHz,it could only run@2000MHz or maybe lower,so i changed for a better heatsink and a bigger fan(fan,i think Tt maybe a good choice),now my Athlon is at 2200MHz(200*11,normally 45c).compared with mine, your systerm's got 13c higher,pay attention,i don't increase
the Vcore and i don't want to do that,high Vcore will bring more heat,but not too much scores of 3DMark,it's not worth doing that, i think.so if you want me to give you suggestions,i'll tell you overclock your CPU in range(don't increase Vcore especially),you'll get a fine temp and a fine power.
The only pity i've still got is i think this motherbroad is not good to use,it didn't give me any good feeling.How's your motherbroad,my friend?

Ok I went ahead and bought Vantec AeroFlow VA4-C7040 HSF. Have just booted at stock speed and vcore and have been surfing the web for the last half hour and my idle temp has dropped to about 39*C.. Not bad, from what was around 47-48*C a nice 9*C drop. Fan noise is a slightly louder then the stock AMD cooler if I listen really carefully but nothing overly noticebale.

Now to do some overclocking and prime95ing to see how she goes at load! Will report findings soon

Ok so it has only been a couple of hours but I have got prime 95 running stable for over an hour with FSB@200mhz & multi of 11 giving me 2200mhz with the vcore@1.775 (although It still undervolting to around 1.74 in MBM5) .
Will leave it running over night to stress test it properly, but so far have found my idle temp with vcore@1.775 is 43*C and max temp under load is 48*C.
I Am pretty happy with that as it is 10*C less then what I had with standard HSF when I was running FSB@ 190MHZ and vcore@1.725. Also its nice to see the bios, windows and WCPUID all show my cpu as an ATHLON XP 3200+.

Anyways looks like I got to the 200mhz fsb I was after. I would highly recommend the Vantec aeroflow, definately a big improvement over the stock AMD coolers......now, the next question is I wonder how much further this little barton can be pushed

Look like that pig aint squealing that much with you after all. Those stock HSF are pretty good as long you dont have to up the vcore.
