1800+ @ 1729mhz

[ShadowFolder]

athlon xp 1800+ @ 1729 (11,5 x 150mhz, 1.856v)
kingston 266mhz ddr cl2 (o/c 300mhz, agressive settings)
cpu:46, system: 48

i think it's not stabile,
windows xp run without crash or any error,
pcmark 2002 run perfectly,

but,
3dmark 2001SE crash and kick me to desktop,
and
some app's gets little errors
(right button menu's hangs on screen)


any advice 4 stability?
(ddr & agp voltage, spread spectrum, etc...)

[The Coolest]

Are you sure your system's running 48C???? How is that possible when the CPU is running 46? :eh?:
Try downloading Prime95, and run it at torture setting, it can either be your RAM or the proc, or it might be heat, check all that, and either try to release the RAM settings or try to lower FSB to lower the CPU speed and run prime 95 again, if it doesn't fail for 24 hours, or at least a full cycle then you propably stable

[Morbid]

You might want to turn that Speed Spectrum off, it's very bad for overclocks. What it does it increase the CPU speed every now and then to make up for EMI (electro-magnetic interference). Atleast, that's what I make of it.. perhaps someone can confirm this or correct me.

Sorry.. you can ignore this. I thought you said SPEED Spectrum.. not SPREAD Spectrum. My apologies. :(

[ShadowFolder]

yep, kt333 chipset gettin really hot... (and active cooled)
i think my mobo's voltage not enough 4 extreme o/c (msi kt3 ultra)

temps looks not bad 2 me, (under 50C)
maybe mem's getting trouble like u say...

[ShadowFolder]

yea, i know (spread spec. disabled)
esspecially 3d apps crash very badly,

anybody wanna speak about, ddr and agp voltage?

[specific]

yes, that system temp is odd. are you reading that in the bios?
if not, maybe you should, just to check. 38C sounds reasonable. but not 48. especially when your cpu is 46C!
i haven't gotten a stable 1729 out of my xp1800 either. but i refuse to let go of my bios tweaks! i really wanted that number bad too. it reads as xp2100 in wcpuid. i got 256 kingston too.

edit*
unlock that thing, then you can use 12.5 or 13x multiplier, and back off on that ram oc.

[ShadowFolder]

i think that temp r real, because:
cpu cooled real good, but chipset not,
and my agp warm up too much...

if i increase my agp & ddr volt. can anything damaged?

[The Coolest]

CPUs are rated to run at maximum temps of around 90C, so 46C is no where near that rated maximium, while chipsets have a much smaller maximum case temps. I think you should check out for any problems or anything, check the temps in the BIOS and see the BIOS will report to you, I just can't see a chipset running higher than the CPU, unless the CPU is either chilled-water cooled or just simply super cooled, sorry.

IMHO you shouldn't really raise any voltages untill you get the system temps under cotroll, maybe adding some case fans to increase case air flow, that can really help. also the contact betwin the chipset and its heatsink my be loose, you might want to check that possibility to see if it's the problem

[ShadowFolder]

yep, i know case not cool enough, (it's open case 4 test)
but temp not high 4 crashes...

cpu not unlocked yet,
i try high speed fsb with default multiplier 4 higher bus speeds
(300mhz 4 now)

[The Coolest]

46C isn't high enough temp for crashes for the CPU, maybe but a 48C on the chipset it WAY TOO HOT, this might be the reason for your instability, or it might not be it. I think upping the volts to the mem won't hurt anything and will only let you know if its your ram or not which is failing you. My bet is its either the CPU or its the chipset, because I wouldn't expect it to work right at such high temps. It still could be the ram, you better reduce the ram settings than upping the volts just to see if its the ram that is holding your overclock

[ShadowFolder]

understood... :)
i'll reduce mem timings...

it's not good mobo 4 o/c (no divider 4 pci speeds :()

new target: 2ghz & 2 volt with mod... ;)
(a have no idea 4 voltage mod, but i'll need 2 volt @ 2ghz)

[Angryviking]

whereismy386,
I think you have reached the limit of that particular chip. The 1800's have never been high-yield OCers. (Just check the OC database and compare to 1600)

I gave up OCing my 1800 (sitting in it's box, on the shelf now). I tried every trick and mod possible...wasn't even stable at 1700 !

Now this 1600 :D Totally different story - almost zero effort and its running at 1750

Keep us posted on your efforts. Sorry, I have no suggestions, other than what has already been mentioned.

[ShadowFolder]

yipeeee!
3dmark2001SE runs perfectly stabile!!!

i cool chipset,cpu and agp with two 92mm 12v fan,
and it really work!!! :)

agoia-9 xp1800+(palomino) @ 1729mhz with air cooling!!! :D

(and stabile!!! ;))


EDIT:
cpu=42C,
system=40C
(idle ;))

"CPUs are rated to run at maximum temps of around 90C"

Morelike 70c, as stated by AMD. As for your voltages, i'd say dont go above 1.85vcore atm, as your current cooling doesnt seem adequate to facilitate any higher than that. For memory, i'd say 2.8vdimm is fine unless your going to very high FSB.

On the issue of the case Temperature thing, thats most likely an incorrect reading. If you know anything about temperature and airflow, you should realise that if the ambient air in the case is 48c, physics tell you that its impossible for the CPU to be at 46c, as the CPU fan is drawing air form the case. Remember this:-

Die temperature (core) + ambient temperature (air, i.e. room/case) = CPU temperature

When following the equation, it shows you that the reading is obviously incorrect.

My guess is your mixing up the sensors when using MBM5 or whatever equivilent. If you ARE using MBM5, make sure you have the latest version, and are using the correct sensors for your motherboard, you ca find the motherboard manufacters list by simply scrolling down the list, its on the left menu thingy.

link = http://mbm.livewiredev.com/

If your NOT using MBM5, then USE it, that will eliminate any possibility that its some other software fault.

If the temps are still the same, after setting it up to use the correct sensors, then check in your bios health screen to again, confirm that the readings are not software related. If the bios is still reading those temperatures, make sure you have the latest possible bios, i've had old epox bios which reads temp wrong, so dont worry jsut yet.

After that, if the temps are still the same, they must be correct, but reversed. The highest is always your CPU, so 48 = CPU and 46 = Case more than likely.

JUst a few points, oh , and test temps with your case side off to see if that lowers case temps.

Post back your findings, and we'll help further

[daS_mAgg0t]

LOL wtf.....hmm, does the northbridge give the case temperature reading ?

[ShadowFolder]

sorry, but what's that mean?

[daS_mAgg0t]

Sorry that wasnt directed at you, i'll start a seperate thread, but judging from your other temps, they look decent enough, that case temp is still high though. With adequate cooling, your case temp shouldnt be much over room temp. Mine is only 26c, im fully air cooled as u cna see.

Now i dont actually have any extra cooling on ym northbridge, although my sig says i have a Zalman and mini delta, thast true, but there not installed yet, im waiting till 2moro.

[ShadowFolder]

whatever,

agoia-9 xp1800+(palomino) @ 1729mhz with air cooling!!! :D

(and stabile!!! ;))

it's runs like a lightning! :)

[daS_mAgg0t]

Well....thats great, try and get that case temp down though, it'll do wonders for stability. Oh yeah, and i can post at over 2ghz easily on air, doesnt mean its stable though ;) try some stability tests

[ShadowFolder]

i think, i need 2volt for 2ghz... :eh?:
do u know any voltage mod 4 "msi kt3 ultra"???

[daS_mAgg0t]

nope, and im only at 1.85 max, i said post though, not boot windows ;) I need a new PSU to get further than i am at atm, but i reckon for 2ghz to be stable or even boot windoze, i will also need 1.9 or 1.95 volts to get to 2ghz stable. So im affraid i cant help you there, i need a mod too, or a new MB :D

[ShadowFolder]

i read some articles about, xtreme voltage mods 4 msi kt3...
but they're looks 2 me too dangerous :(

mmm...
have u any idea 4 "what is ddr hlck+33 setting on bios"???

[daS_mAgg0t]

Im would assume that is the setting to push your memory to DD3 333 i.e. 166mhz

If your memory is rated to/supports PC2700/166mhz, then use it, you'll get that little bit extra speed.

What it does it speed your memory up by 33mhz FASTER than your CPU bus speed. You current memory and cpu bus speed are 133mhz. So using it would push your memory to 166mhz. It isnt as near as effective as it would be on an intel system due to the bandwidth limitations of the athlon XP, but it does give a little extra speed, so using it wouldnt hurt ;)

[ShadowFolder]

150x11,5=300mhz ddr bus speed... ;)
so what'll happen "if i enable hlck+33"???

mmm... i love amd :D

[daS_mAgg0t]

tbh....im not actually sure...im not sure if it will take your mem speed up alongside it, i.e. to 183mhz asynchronous, not sure.

However, know this, Asynchronous setups, unlike those on intels, are ****ty on AMD.

Its all down to the XP being limited to 2.1gb's of bandwidth, i.e. dual pumped bus, 133/266DDR. Unlike the P4, which is quad pumped, i.e. max bandwidth of around 4.2GB's.

Running 2700/DDR333 on an intel system would get you about 2500/2600 scores in siasoft sandra, with an asynchronous setup, pretty close to the rated 2700 specification. The memory is allowed to achieve this because or the P4's high banwidth allowance, as i said earlier.

However, running this on a XP would only get 2200 or so, because the chip is stilllimiting the system to 2.1gbs of bandwidth, so the asynchronous setup is not very benificial (asynchronous means running the CPU and the memory at different bus speeds incase u didnt know).

Overclocking your CPU DOES actually help things along, as raising your FSB raises you CPU bus speed, therefore ups the maxium bandwidth. At 150FSB, you CPU's max bandwidth is now at about 2.4GB's instead of the default 2.1GB's. My advise is get the highest FSB possible, as that will improve your memorys speed/bandwidth PROPERLY.

I recommend unlocking your CPU if u havent already done so, lowering the mulitplier and upping the FSB as high as you can so its stable to get the best TRUE bandwidth from your memory.

[Tebore]

Wow that's a nice O/C i'm having problems hitting 150 myself (AGOGA). I can only hit 147FSB at 1.775volts mem at 2.73v temps are 48CPU(SK6) and 31Chipset. I can't seem to get any more out of the Chip and Ram at those voltages. Oh i suggest doing a Burn in on the memory and CPU at max voltages. It got my another 3 FSB. I need suggestions

[daS_mAgg0t]

Telbore, dont suggest putting voltages at max to an average OC'er, they may just do that and keep there clockspeed the same, what you gonna tell them when there CPU dies ? ;) Remeber some boards support 2.2+v now for vcore

You dont need to burn in, dont worry, as long as ur pc isnt BRAND new you'll be fine.

[ShadowFolder]

yea, amd not cool like new p4's...
(but it's cheap then intel, and unlockable ;))
whatever, i satisfy @1729mhz, and it's stabile,
so there's no problem :p

tebore, i can say three word:
voltage-cooling-mem settings

my xp r agoia and stepping 9
so your agoga r not o/c able like agoia
unlock your cpu, and try 140x13...

[ShadowFolder]

WTF! that's totally disappointed 4 me! :(
i try reboot o/c ed 1800+ and, crashh! :eh?:

more then 10 attempt load windows....
so i need more fine tuning mem settings :)

[broken003]

I think I was able to get about 1770MHz 1.85v on air with my XP1800. I think the temps were like 47C full load. Now I run it at 1838 (still 1.85v) water cooled at 39C full load. I think adding heatsinks to two hot chips on the Mobo is what also helped in the overclock.

I had hoped for 2GHz, but I couldnt get it. The highest I got was 1909MHz (11.5x166) with 2.1V. It was stable, but I prefer to back it off just a little to keep the voltage and temps down.

[ShadowFolder]

1909 huh?
not bad! ;)

ok, i think when we reach 2ghz~, palomino adventure'll over...

let the clawhammer o/c begins! ;)

[daS_mAgg0t]

n/m, found it, nice OC that man, im aiming for 2ghz atm, need a new PSU first tohugh, damn 5v+ rail stopping me go further :(

[ShadowFolder]

350W oem psu here, and looks enough 4 stabile 1.8ghz :)
