I'm getting 37.5-38C idle and 41-41.5C load for temps. My cpu is locked because I changed the multiplier in bios and my cpy speed stayed the same when I booted back up.

I only have 1x 512mb of geilpc3200 and was wondering what I have to do if I only want a 200-400mhz overclock.

no change on the FSB/RAM ratio, that PC 3200 can do 200mhz on stock, and ur chip only do 166 on stock, what u would do is go into the bios, and raise the FSB to 200, i suggest to take a stop at about 170 or 180 and see if it's stable, then keep on pushing it, as for where to find FSB adjustment u'll have to go to ur mobo manual, it should be in there, i don't own this board so i honestly don't know.

got it at 176fsb, and running fine at 1.95ghz. My idle's are still the same (37-38C).

I should be safe overclocking the cpu right? No damages to shorten its life as long as I don't screw with voltages?

EDIT: My load went up 1C, so now its at 42C. Keep pushing it?

warlock110
02-21-04, 12:24 AM
i say keep pushing it till ur loaded temp are ~50C, it's loaded temp so ur idle should be around 40-42C. ur chip runs at 1.83 ghz, so u should up the FSB to 200 and see what happens, if it locked up then clear the CMOS, i say hit a 190 FSB on it first and see if it's stable in Prime 95. Wut heatsink u got on there?

warlock110
02-21-04, 12:26 AM
actually i think any OC will shorten the CPU's life, but CPU are bulit to last, u'll be changin it again in 2-3 years, don't worry about them, besides if u are on air cooling u won't be pushing it very hard :) i forgot 1 thing, did u locked the PCI and the APG speed?

nightmare3215
02-21-04, 01:04 AM
i have a thermalright alx-800 hs and a panaflow h1b for the cpu fan

Edit: I didn't mess with the pcibus or agp speed at all

just set it to 200Mhz FSB and advance from there

nightmare3215
02-21-04, 12:39 PM
I got it up to 2.1ghz at 190fsb and have been running prime95 for 3 1/2 hours now w/o any errors.

prime95's still going and my load temps are 46C. Keep pushing?

warlock110
02-21-04, 04:26 PM
i guess u can do 200, but anything more than that is a little too hot IMO :), looks like u got some good stuff, just keep pumping it, i personally would stop at around 210 or 220, it really just depend on the chip but that barton can do alot, 2.2Ghz is good already.

nightmare3215
02-21-04, 08:48 PM
I changed the fsb to 200, and windows would allways restart, so I'm back at 190fsb. I suppose I would have to up the volts in order to get it at 200fsb?

adelphia83
02-21-04, 08:55 PM
Yes! Up the voltage on that sucker.

You won't shorten the CPU life considerably (beyond how long you'd use it), so see what you can get out of that thing.

Increase voltage, until you are uncomfortable with your temps. I'd say anything above 2.0V is bad news on air cooling.

I've got an SLK-800A w/ a 2500+ (unlocked), and barely manage 50C at full load at 2300mhz.

nightmare3215
02-21-04, 10:48 PM
Allright, I'll up the voltage till' it loads windows and runs prime fine for 1 hr.

One question, lets say I turn my computer on for only 6-15 hours a day instead of leaving it on all the time... How many years at least would it be before my processor died? I know you can't tell for sure and all, but can you give an estimate?

adelphia83
02-21-04, 11:22 PM
Here's some food for thought:

I have an old AMD K6/2-400 overclocked to 475mhz running 2.7V. That's almost a 20% overclock, with a 23% increase in voltage. It was my primary computer for three years or better. It is still running to this day, almost 6 years later.

A 2500+ Barton CPU running 2.2ghz is about a 22% overclock, a little less. If you were to run this CPU at 1.85V, that is only a 12% increase in voltage. Hardly a justifiable amount in terms of CPU lifespan.

You'd have to run ~2.07V to have a 25% increase in voltage, which has been done sucessfully for years in older CPUs.

I also built a system for a friend, which has a Tbred-A running 2.1V to obtain 2.0ghz. A 40% increase in voltage (stock is 1.5V), and this has been going steady for a couple years.

You make the call...

Allright, I'll do it!

Will this extra 100mhz help me in games at all? Just a little?

warlock110
02-22-04, 01:11 AM
for benching only, 200mhz will not be noticable :), but if u bench it'll show. hell i say up the votage a little and get 200FSB in there, u can say that u have push ur barotn to an XP 3200 sounds better than to tell someone i'm at 2.1Ghz on my barton :)

nightmare3215
02-22-04, 01:37 AM
at 200x11, will I need to up the ram volts as well?

warlock110
02-22-04, 01:50 AM
no, ur ram will do 200mhz on stock, that's wut PC3200 do, anything above that and u might need to. but for 200mhz i would say no.

nightmare3215
02-22-04, 01:54 AM
k :D.

You think I'll need to push it up 1/2 a volt or 1 whole volt?
I just ask because I'm going to do this all later on in the morning and would like some predictions.

warlock110
02-22-04, 05:21 AM
1.65V is stock
so i'm guessing 1.7 or 1.75, either way it won't hurt, i've seen people stoping at 1.85 mostly, nothing more than 1.85 though that's too much for air.

nightmare3215
02-22-04, 12:34 PM
I've got it at 1.7v and Im in windows fine at 11x200. I'm going to run prime in a bit to see how stable it is.
EDIT: Load temps now are 44.5C

If I increase the agp voltage, can I overclock my graphics card some more too?

warlock110
02-22-04, 03:37 PM
nah, don't OC the graphic cards, the performance is not noticable but the chances of perminate damages are much higher than the CPU. if u want u can go over to the graphic card forums and ask, they are much more knowledgable on the subject.

adelphia83
02-22-04, 07:51 PM
Actually overclocking the GPU can improve performance greatly, which varies depending on the graphics card.

Non overclocked, my 9500Pro gets about a 13000 3DMark, which jumps to 15000+ after a little overclocking.

Increasing the AGP voltage will do absolutely nothing to achieve an overclock on a graphics card. When overclocking the AGP voltage, you are simply adding voltage to the AGP bus. If your goal is to run super high AGP frequency (>66mhz) then be my guest, otherwise this just promotes instability.

The GPU voltage is controlled by the graphics card itself, and cannot be changed through the BIOS.

I ran prime95 for about 10 minutes while going through webpages and I got a bluescreen that told me that windows was shutting down to prevent damage to my cpu. So I upped the volts to 1.725 and I'm going to run prime again at 6 today when I get my tt smart fan II in the mail. Maybe I'll get better temps :D

BalliN
02-23-04, 12:24 PM
yeah.........thats a good idea to put a new fan but also what type of paste are you using. I upgraded paste to as5 and temps went down about 5c -7c. Also it took my barton 2500 1.75v to run prime stable at 2.2ghz or 200x11.

Your temps do seem a bit high to me for that speed........but there not too bad


Peace,

as5 I've been using. and load is now 48C with it at 200x11.

nightmare3215
02-23-04, 04:51 PM
Windows blue-screened again after 15 min in prime, so now I upped it to 1.75 and am running prime again.

Don't feel bad. I am running almost the exact same setup. Keep in mind that the Artic Silver may take up to 3 months to fully cure on your CPU. I have had my setup for 3 weeks now and when I first set up I couldn't get above 185 stable for the life of me. Now on the 3rd week I am geting 195x11 on my locked Barton 2500.

Also contrary to what was said above, 200 Mhz on the CPU is a world of difference on the AMD side. Think of it, u run a 2500 rated cpu of a 3200 cpu. Which is gonna do things faster? Definatedly the high FSB proc and u will see the difference, especially loading maps for games.

nightmare3215
02-23-04, 08:26 PM
Prime's been stable for 3 hours :D

Looks like 1.75 is a majic number :D

I just got a thermaltake smart fan II in the mail with the coolmod. I was wondering how to hook up everything with the sensors, and how I should set up my fans.

Right now, I still have the panaflo pushing 39cfm over my hs and I still have my coolermaster pushing air out of my case. Should I have the smart fan for intake, out-take, or for my hs? Should I even use the extra "cool-mod" at all?

Edit: the fan itself came with 3 wire sets sticking out of it. One that connects to the motherboard for power, one that has a blue jumper on its pins, and one that has bare pins. How should I set this thing up? The instructions that came with it only told me how to hook up the "cool-mod" fan grill to the hdd and power led sockets in my motherboard. If I can't use the mod with my case led's, I consider it useless.

BalliN
02-24-04, 08:42 PM
if you don't have any intake in your case I would either move the panaflow or the tt as an intake for sure. If you only have exaust 1 fan and psu, your probably not getting the best air flow in your case and could be the cause of your temps being a bit high.

You should have a sensor wire. You can put it either on the cpu or on the hsf (as close to the cpu as you can). I believe it also comes with a manual control thingy that you could use if you wanted. If you don't setup either I think it runs at full speed. The LED thingy I'm not too sure about that.

I looked into that fan about 2 mo ago and thats all that I can remember about it.

Edit: If you choose to use the tt as a case fan I'd use the manual control.......cause it might be a bit load for you. If you use it as cpu fan use the auto contol sensor. But I'd definetely move one of them too intake forsure.

Best of Luck

Just be glad you dont have a XP2500 like mine...wont do 2.2Ghz (200FSB) with less then 2v's...

But remember, just because it is stable in Prime doesnt mean it will be stable in 3d gaming...

Best thing to do is...run prime for a day or so and if its stable that long...run 3d mark 01 or 03 in loops for a few hours...if your system can do both Prime95 and 3d marks without crashing then you can say your system is stable at those speeds ;)...

Luck of the draw. Most (not all) 2500+'s are hitting at least 3200+ speeds (200x11 = 2200mhz). Mine is about average for an overclock on these chips, 2300mhz. Some overclock to 2700mhz or so, some only 2000mhz. Your results will vary of course, as it's the nature of overclocking.

My CPU is being cooled by a TTSF2 on top of an SLK-800A.

I recommend going with the manual control, as long as you remember to turn it up during CPU intensive apps. It all depends on your overclock however, you will need to adjust speeds according to temperatures. It will take a few days of monitoring temps under different circumstances to figure out what the best fan speed is.

I've found this is the only way to maintain reasonable noise levels with this fan. With the sensor put adjacent to the CPU, the fan would run 100% full time, which is VERY hard on the ears. With the sensor placed away from the CPU, it would overheat sometimes during 3D gaming, without ever reaching full speed.

I was playing need for speed underground for about 30 minutes yesterday ( I know 30 minutes isnt a lot) with maxed out graphics settings and I didn't have any problems.

I had 1 exhaust fan, plus the exhaust fan on the bottom of the psu, but yeah, I used to not have any intake.

Now, I'm going to use the tt fan for intake, and keep the coolermaster as outake as well as the panaflo for the hsf. If I don't notice temp improvements, I'll switch things around a bit.
I'll test 3dmark and prime more tomorrow, its getting late and I need to do some homework. ;)

EDIT: I put the tt sf2 on the heatsink and put the panaflo in the front for intake. I haven't used the "mod-grill" because I don't know how I'm going to fit it on the fan, on the heatsink... I'll try that tomorrow too.

I ran Prime again under 200x11 and it only lasted for 1-2 hours, then I lowered my vcore back to default, and set my fsb to 190. I tested prime again and it lasted for 4 hours before it was cut off... you think that I should try to raise the vcore until I get stable for 24 hours in prime under 190x11 before I try to get completely stable at 3200+ speeds?

Hi nightmare3215.
Your on the right track if you can get into windows at 11x200. Keep upping the Vcore .025V till you get 12+ hrs prime stabile. Try to keep that load temp under 50C though. Is your memory on SPD timings and auto V?

glock19owner - I totally agree with what you said about being prime and or memtest stabile but not being 3D gaming stabile. Eventhough I got through 12hrs of prime and 8hrs of memtest test #5 @2-3-3-7 220FSB with the setup in my sig I still had to loosen my mem timings to keep UT03 playing smooth.

true, but increasing the agp voltage a notch does help some systems (mine included) stay more stable when oc'd

Get rid of the system and video BIOS shadow. It just wastes memory address space. It was actually beneficial in older systems, and helped to speed up access to the BIOS considerably, but has been shown to do absolutely nothing in newer systems. Do a search on google for more info.

I've always had problems overclocking with the spread spectrum enabled. What this does is vary the clock frequencies a small amount constantly to reduct EMI emissions. If you are not having a stability problem caused by EMI, I'd suggest turning this option to disabled.

Be sure to keep an eye on the memory frequency, make sure it's not going above it's rated speed, as you will be unable to tell if it's the CPU or memory limiting the overclock. If you have to, you can adjust the FSB/DRAM ratio to maintain a certain memory speed, but for best performance it's best to leave this at 1:1 with FSB.

nightmare3215
02-25-04, 05:13 PM
So I am going to disable the spread spectrums and the system and video bios cacheable marks? Should I change the dram setting from auto to 1:1 then?

glock19owner
02-25-04, 05:20 PM
I keep mine at auto...I actually have higher memory bandwidth keeping it at auto then at 3/3 or any other adjustable settings...

Prime stable for 8 hours and 10 minutes at 2080MHZ and 1.675 v.
I was surprised at the high load temps I got when I looked at it this morning, 50C, and I only upped the vcore .25....

Yesterday I ran it for 2 hours, and it was at 43-44C when I looked at it. It was at the same voltage and clock too.
