overclocking amd 2800 athlon xp

Hey inacoma, I have a thermaltake fan, and it roars. (oh yeah and I changed the fan..) Dr XP is right about these.. I think they are great because you have a decent block of aluminium with the copper base (they vary a bit) The size of the cooler is good for smoothing the heat response when you kick the cpu into action for heavy load. (in my opinion - I got to this conclusion after finding one cpu would totally flip out due to thermal overload with a smaller heatsink and same fan). Oh yeah, and push the Vcore (going higher with FSB does need more but not much, than if you change your multiplier to say 14 and reduce the FSB)!

Hey Dr XP, you sent me a reply with a link to one of those heat pipes.. you know anyone whos tried one of those bloody great heatpipe contraptions? Any hey whats your other system (please dont tell me its water cooled

 

hey all

well i tryed to playing around with the settings
made fsb higher, vcore higher and multiplier lower but it wouldnt let me get into windows

the most i can get is 178fsb with 1.7vcore and 12.5x

 

hey inacoma and all,

Hey inacoma, I am running the below specs but I am at 177 fsb & 12.5 with a volcano fan. It seems very stable running all of the HL2:Source games.

I was also wondering if I should move my ram settings:
sdram....
active 6
ras to cas 3
ras precharge 3
cas latency 3t

my vcore is now set for 1.75
**idle stemp on my processor is
cpu is 35c/95f
mb is 16c/60f

Is this acceptable?
I dont see the processor get much hotter than this, even with a small load (using asus probe)


just curious...i am still stuck with 2700 ram

 

hello, molks my other system is :

asus a7n8x-x
amd sempron 2400+ not oc yet
gigabyte 3d cooler pro max speed 4400rpm
(artic silver 5)
256 ddr pc-2700
nvidia gforce fx 5200 128 oc core:266 mem 466mhz

** water no!! i love air fan cooling love the noisy**
im still working with this syst is not done yet so ill let you know when is ready to show!!

 

inacoma what mobo you are using?
molks about heatpipe tech i have read a lot all test said they work i had the gigabyte 3d cooler on my 2nd syst work great i got for my 2800+ xp originally i was getting 49-52c idle and 55> load (oc to 2.21ghz,vcore 1.7). with the gigabyte and artic silver 5 cut the heat to 37-41c idle, 45-49c load as you can see is a good hsf and pretty silent. now about those huge thinks like thermal take silent tower they are to big to really fit in most cases dont know nobody with it but all the forum said the really work

 

Hi all, well I have been lurkin in here for about a day and gosh you guys and gals rock. I have Oc'd my amd 2800+ to the specs in my signature. I have a few questions as well. I know my fan rpm is 3300 but no idea what the fan is, this is a custom built computer I had built by a guy here in Tampa.When my comp was at factory specs in idle it ran at 64 degrees and under load was MAXed at 73 degrees. I assume this is Celsius.I used the TOAST program to run it underload. But after overclocking my CPU it runs the SAME temperture. I did not up the volatge although I suspect I can get higher numbers if I did. I measured the sys temp by using the pc health setting in my bios. I installed a prog that measures for me Motherboard Monitor (MBM)but it reads 55 degrees idle but 73 under load. I am looking into a better fan and saw a COOLING forum, so I will look there. I trust the pc health setting more. Here is what I made my settings in BIOS
CPU host Freq 179
DRAMClock 166-DDR333
CPU voltage is AUTO (runs default of 1.6)
AGP overvoltage is AUTO
DIMM overvoltage is AUTO
I also have a Nvidia 5700 LE 256 mb Video card (Does this matter?)
And the fan RPM is 3300.
I think I should be satisfied with what I have, but I had it at 2.7 GHZ lastnight and brought it back down, due to PARANOIA. It didn't register in XP as anything other than AMD ATHLON. I can reproduce this clock speed, but am not sure it is safe. It ran under TOAST for about 20 minutes and then it failed. MY question is at normal settings my temp was still high and has been for the 2 months I have had the comp, I assume. Nothing changed with overclocking, so what is the NORM? I hear no to let it go over 55 and they melt at 85. And what is a MOBO? I am new to forums, so I apologize if I have made this too long or posted in the wrong spot. If you need more info please ask and I will be happy to give it to you. You might have to tell me how to get the info too. I am pretty computer stupid, this is a bold move for me LOL... Thanx

 

oops should be 2.27mhz not 2.7 hee hee I am dunb

 

Hi, 73 C is pretty hot, but the vcore being so low at a decent 1.6V means the CPU is not heating itself up too much so to speak (Watts produced not too great). 2.27Ghz aint too bad with that Vcore - even with those temps, I'd say that your results fit in with whats expected.

I trust the MOtherBOard monintor you use, and the PC health readings can be wrong, Ive heard of BOIS updates making quite a difference to the readings.

When overclocking with a certain Vcore you will find using the Hi/Low menu in MBM5 that the Vcore will fluctuate. This will mean that for an instant or period, the Vcore could be too low for the overclock you are forcing, and there will be failure. This may be why TOAST cut out.

Dude if you had got 2.7 Ghz with that 1.6 Vcore Id have made a very generous offer for that CPU. :]

 

inacoma, Just wanted to know a few more things about your system, like whats your memory like and about the power supply you have? You should have a go at putting the multiplier higher, with a low FSB, and see what happens if you increase the FSB slowly. You could try 15 mult, 140 FSB and go to 150 and bit higher, = 2250 Mhz. You might get a better OC, with more stability. I am running another XP this kind of way to get better oc. (Alot of people will say, and they are right, that the lower memory speed is a bottle neck, but for pure processing power the MHz count. Its just an interesting thing to see if its more stable)

 

Hi everyone,

Just wondered if anyone had some advice on my previous post.

I love all of the information on this forum. Keep up the good work.

Hey Capn, I have a Thermaltake K7 11+ fan on my cpu. U sound like you may have a stock fan because your rpms seem kinda of low. If you are overclocking, I recommend a better fan. Of course, expect a lot more noise. I have neat set-up because my case is in the next room. You might want to add a case fan too. Move as much air as you can tolerate noise.

I recommend using http://www.newegg.com/ for all of your parts. I have had the best experiences with them, they are fast and alot of the times their shipping is FREE. If there are other VERY good websites out there for parts I'd love to know what they are.

Thanks everyone

 

HI all, thanks for your input. Yeah I wish I really did get 2.7 out of it LOL. Anyways, I am looking into fans for cooling off my processor, and am going to call the guy who built my comp, he can prolly get me a great price on fans. Thank you for the links as well.I have a decent case fan I hear it whirring right now. I have looked at my case and see NOWHERE else to install a new case fan, unless I get out some tools. Not sure I am going to go there though. I looked in the cooling forum on afterdawn, but saw no info on actually installing a new cpu fan. Is this a difficult task? Will I be simply replace the current one? Will they bolt right up? So many dang questions LOL. I looked at the volcano 11+ I think it was and it is right in my budget, still spendy though, for a fan, wish one of those 9.00 jobbies would work!
Also a lil set back. I am now back to 2083 ghz as it seems when I play Unreal Tournament it locks up and I have to reboot. Funny that I can play UT2K4 for 2 hours with no prob, but UT99 locks in about 5 minutes flat. I cannot give up UT best damn game ever! I read that older games can do that sometimes due to overheating where new games will not be a problem. I should have a new fan by today (if my guy comes through) and if I have a major problem with installation, any links you can reccomend? Thanks for your help all!

 

hey Molks

ok my memory is 512ddr-sdram 3200,
my power supply is 350watts

well i had my settings at 178fsb with 12x with 1.7vore
when i played underground 2 my pc would frezze the temp would go to 62c maybe because its like 30c in melbourne, australia,

well i am going to try what you said and i will keep you up to date with my oc settings

 

hey molks

i tryed what you told me to do but my multiplier only is to 13x ??

 

HI guys thanks for all your help! Things are going well now that I have installed my Volcano 11+. I have updated my signature to the improved settings and now I run idle temp of 51 and max 56 under load running TOAST. Dang it is loud! Cant imagine the 12! But I can see why some like it! LOL Thankx again all. I am sure I will be tweeking some more and will keep you updated!

 

The 12 is a beast. Its like having an apache in your room or something. I used that, plus some other fans to get my Athlon XP 2800+ to 2.4 Ghz (Extremely Stable) and operates no higher than 90 degrees Farenheit.

 

inacoma u juz cant be serious!.....u cant do any serious overclocking with a 350W PSU u need to seriously consider an upgrade i had to upgrade mine to a 550W PSU but thatz also cuz i have a seriously power hungry system but if u seriously want to achieve a serious stable overclock without major voltage shortage, or any serious voltage fluctuations during system load!
So in conclusion the most likely reason for the system not to go over that overclock might be the PSU but then again i might be wrong but thats wat i think so u know if anyone else out there agrees or disagrees plz reply!

 

teztous, you are certainly right about being concerned over the power supply, but its all about total drain of amps. This is for all devices attached. More important is stability, and some cheap high power supplies are not so good at regulating the power when it is needed. I am sure that a 350W supply in a system with few hard disks etc and without a power hungry graphics card will be enough for reasonable overclocking but yeah sure for extreme stuff. If you are worried just check the voltage of the Vcore when you start up a CPU intensive app, prime95 is good, you can pause it and continue.

 

kalunjoku, hi there, you are running a similar if not identical system to me. Since the guy raised a good point about the Power Supplies and I have trouble getting more stability, could you tell me what power supply you are using? Also, what multiplier and FSB combination do you use, and well while I'm at it give us the Vcore.. Im becoming an obsessive stability freak, if thats possible..

 

ok guyz so i think we're goin wit de whole PSU issue....well i have prepared a basic short and simplified guide for the purchasing the perfect power supply.....here goez nuffin
(1) Wat do u need...wat does ur system need....is it a big mean ass gaming machine with alot of HDD'z and a mean ass GPU and alot of hardware or is it juz a basic office system with a singel HDD and low level GPU
(2) W! How many watts does ur system require to run stable at stock or how much W extra would u need to top out overclock with optimum stability
(3)Make sure that u buy a PSU from a good brandname company not some sleazy arse panamanian company that uses cockroaches as V. regulators
(4) Make sure that the PSU supports the voltage provided by ur country if its 110 or 230
(5) Choose a PSU that is adequatley cooled and pereferbly 'QUIET'
(6)LOOKS! this might not be the biggest point to some ppl but to some ppl like moi who like to mod their systems and likes to do a lil bit of flashin every now and then....if thats you then u should opt for a good lookin PSU with LED lights maybe and UV sensitive molex headers and other connectors!
(7) CABLE SLEAVING! Trust me get a PSU that has all of its cables sleaved it juz way too much hassle tryin to tuck away those excess cables!
(8) Get A PSU that has enough molex headers to suit ur needs but dont get too much cuz thatz just SELFISH ;p hehe no its only cuz ur gonna have trouble hiddin the extra cables


Last but not least...

GET THE 550 UV SENSITIVE ULTRA PSU! IT KICKS ASS TRUST ME ;p

 

hey all out there

thanks for the info teztouz i will probley go get one next week

i just got a new cpu fan COOLER MASTER JET 7+ what you guys that about that fan ??

so when i get the new psu i will tell you about my oc settings thanx
