Overclocking a Thoroughbred 1800+

[AirTrax]

Hey guys...i've had this processor since december. I'm not too sure what stepping it is and what model it is because that would require my taking off the heatsink and then reapplying the damn AS5, but I do know it's a thoroughbred. ANyways, i just wanted to ask you guys a proper procedure for overclocking this bad boy. I understand the dynamics of overclocking kinda, i wanna up the FSB or the multiplier or the voltage right?

My setup right now is a Asus A7V333 motherboard with the AMD Athlon Thoroughbred 1800+ (266MHz FSB) and i have one stick of Samsung 256MB of ram and another stick of Kingston 256MB of ram. Both are PC2700. I also have a Thermaltake SLK-800 heatsink with AS3 applied on the core. I have a 80mm fan running on top of the heatsink from SVC. I also have 2 rear exhaust fans in the back and 2 front intake fans. I guess that's all you need to know, and more =)

What should I do to get a good overclock? Should i up the fsb first? up the fsb and multiplier? up the ram? i doubt i need to up the voltage as it's a thoroughbred right? I don't know, i hope you hardcore overclockers can lend me some insight.

Thanx for reading this and if you spend time to answer my question, i greatly appreciate your kind gesture in helping a fellow n00b out in overclocking =)

A safe overclock with most motherboards is to change the cpu fsb from 133 to 150. Your pci and agp devices should handle this setting with no problem even if your board doesn't have an agp/pci lock. If it doesn't post or windows runs unstable, increase the cpu vcore by .05 volts in increments until the system is stable. If your default voltage is 1.65, try 1.7 to start with. Also, be sure to locate the cmos jumper before trying anything. If the system won't post, hit the power supply switch in back to shut it down. Then move the cmos jumper over one position for 10 seconds (while the system is turned off), then return to it's original position and start over. This will reset the bios to the default settings. If you're unsure about some of your settings, try printing some copies of the bios pages before making any changes, so you'll know exactly what the current settings are.

what about memory speeds? should i mess with that ALONG with the cpu?

 

[AirTrax]

oh also oldie, u say i should bump the fsb, i'll try that. should i touch the multiplier at all?

 

[jswjimmy]

wow someone elce with a xp1800, i have mine running at 2.2ghz right now(but i have hit 2440 with a 1.825vcore). cant wate to see what yours will do.

btw do you know the steping. mines a jiuhb0320

and if it a b core i would start a 2ghz and work my way up till you hit 55C under load. so keep the fsb at 333 the up the mult

 

[thetman]

well, you can try to oc your ram. what kind do you have? basically, your goal is to find the fsb/multiplier combination that is still stable. try different settings and see which one is the best.

my ram is samsung and kingston. i'm not too sure what the specs are on them but they're both pc2700.

i wanna know more about the timing everyone's talking about. what do they mean like 3-3-3 or whatever?

and jswjimmy, if you read this thread again, can u tell me what your settings are so i can try it out because i can't seem to hit 2ghz, right now i went from 1.533ghz to 1.73ghz. anyways, let me know guys

Ddram timings are important, but sometimes you have to leave them at the higher settings to maximize your cpu overclock.

 

[jswjimmy]

12.5x166=2075mhz i can do it on a 1.55vcore
make shure you set it to shut down at 60C

if 1.55 dont work bump it up to1.6 then 1.625 then 1.65 at 1.65 the athlon xp tbred-b should last at least 3 years with good cooling. if you want to up the vcore more to overclock more, then try to keep it under 1.8V but its safe up to 1.9.

then from 2ghz you can work your way as high as the temps will allow. i try to keep mine below 55C under load when in full overclock (2.4ghz) but normaly on a hot summer day i get more like 58C.

and if want to overclock the ram its 174X11.5

I have a DLT3C 1800+ and I keep it at 200x10@1.5 V (1.52 Actual)
for 200x10.5, it costed an additional .1V
for 200x11, it costed an additional .25V
(IMHO,too much added volts for only extra 200mhz)

At default speed 11.5x133, I could run stable at 1.375V (1.4V Actual)

If you have a ThoroughbredB and nforce2ultra chipset, bring the FSB to 200, and lower your multiplier to 10 and start from there. Add volts to your cpu and ram as needed. Your ram will probably need 2.75V or more for stability. You may have to relax your timings for your ram.

I wouldnt exceed 1.75V on air cooling for CPU.

hey guys, i found a pretty good website, IMO, that shows you what settings to make for your DDR Ram, what do you guys think? here's the linky:

DDR Overclocking Tips

i hope that site is true cuz i just might try their suggestions. =)

thats nothing at stock speed mine can run at a 1.15(actualy 1.08 on my an35n) stable for over 8 houres in prime95. and at 2.2ghz i can run it at 1.55vcore. but at 2.2 i have not run prime95 yet.
your right on the 1.75 i dont like to go past 1.75 thats 2440mhz for my chip

hey guys, i have a quick question. one of my friends is saying that a possibility why i can't overclock may be that my PSU is providing too little power. I have a 400W PSU, no name brand i think cuz it came with the case. Maybe that's my problem everything i'm bumping up the voltage? I also have 2 hard drives, 1 dvd-rom drive, 1 cd-rw drive, 1 fan controller, 1 floppy, and 4 case fans and 1 UV light. i doubt 400W. i also have a 9800 pro with a vga silencer on it. I doubt 400W would be eaten from that right?? can you lend me some insight?

and another thing. i know i have a bad ass heatsink, the thermalright slk-800. one of the best heatsinks out there. i applied AS3 like a year ago and now my 1800+ thoroughbred running at stock 1.5V is heating up to like 47-50C idle. Do u think i need to reapply the thermal compound with some new AS5. I forgot to mention that it's summertime and that my room upstairs is very hot. When i first got the cpu and heatsink and i put AS3 on it, it ran 27C at full load with like movies playing, UT2003 running in the background, every single application running. I know that's not as cool as prime95 but bear with me. So i don't know if it's because my room is so hot to create a 20C jump from a year ago. My case set up is what i described above....2 intakes, 2 exhausts, both just recently dusted out. What do u think i should do?

any help guys??? this post has been up for like 24 hours almost

If you intend to overclock, i suggest getting a good psu. Enermax noisetaker, Antec truepower. 380W, 480W should be good enough. As for your Arctic Silver, check it yourself.

I don't think you have to worry too much about the temps right now since it is summer. My overclocked 1800+ tbred was running at 39c idle during the winter but is running at 48c right now.

Here is what I have:

CPU: 1800+ Tbred B @1.909 ghz (11.5 x 166, 1.65v) - The newer Tbred's are multiplier locked at 11.5.
MB: AN35N Ultra
MEM: 2 x 256mb Kingston 2700 running dual channel. (FSB to DRAM ratio 1:1 - 333, upped voltage by .1v, memory timings at default)
HSF: $12 Speeze FalconRock heatsink & fan
PSU: Sparkle/Fortron 350W (cheaper version off newegg)

I successfully ran memtest86 for 10+ hours and Prime95 for 12+ hours once and 10+ hours another time.

i have a stick of 256mb pc2700 samsung and another stick of kingston value ram pc2700 256mb. can i run that in dual channel? plus, what's so good about dual channel if i CAN run in that setup? do u think if i setup dually i will be able to overclock a lot better?
