problems overclocking TBRED B

[peonyu]

Hi, I just got a Athlon xp 2100 tbred b in today and have already overclocked it to 2200+ speeds, im using a good fan/heatsink thats rated for 2600+ so heat isnt a issue. So far when ive hit 2200+ i had 1 error in sandra, and yet the system runs fine in everything else so im not to sure what else to test with cause that may have been a random error, maybe upping the voltage would help but im not sure how high i should up it so any advice on that wouuld be appreciated. Im aiming for 2GHZ.

update: damnit it didnt go to 2300+, the bios reseted it back to default when i did that, though it will go to 2200+ fine. Im beginning to wonder if I got a dud of a tbred b!

Anyways the board is a Aopen AK77-8xn an it resets if it cant boot, so if I up the voltage a little would it allow me more speed, and again how high should i up it at a time and wheres a good safe margin to stop at? Thanks in advance!

What chipset does it have? Does it support a 5/1 divider? If you KNOW it has the 5/1 divider set the FSB to 166. It is possible that your PCI speed it too high causing the system to crash.

No, im not doing FSB oc'n yet, this is just the multiplier so its cpu dependant only. The default is irc 1766 and i got it up to 1866, but after that it fails to boot. If I up the voltage, can i expect higher overclocks and could it hit around 2ghz then, and how high should i increase it, is 1v more good or should it in small steps? Thanks in advance!

 

[peonyu]

come on now i know someone knows this! :disgust:

 

[DannyBoy]

Now comon, how silly can you get :frown:

Your not doin FSB oc'in?

Whats the point in even bothering oc'ing it then

 

[DannyBoy]

Put your FSB to 166, then put the multiplier to 12.5.

There you go, 2.075ghz, thats your 2ghz oc.

This thread is confusing me. Up the FSB!

 

[magomago]

Perhaps his PSU can't push the voltage...or have you tried raising the voltage? And if its isn't a nforce2 I too would wonder about the dividers b/c maybe its too fast

 

[peonyu]

No, i plan on upping the fsb but i want to see how far the cpu can go first cause i dont want to kill it by making a huge leap to 2ghz! And anyways an overclock is an overclock, you guys put to much faith in fsb oc'n, its the cpu speed that im really after!

 

[peonyu]

Thanks for the replys...I really feel the love here :disgust:

anyways yes the cpu only hits 1886 from what ive seen, it wont even post past that..bumpin it to 166 fsb like some of you mentioned probably would have killed it like i suspected

anyways another problem cropped up, i flashed the bios to a recent rev an now XP wouldnt boot so i formatted it, and tried reinstallin it and now it freezes for some reason, but 98 goes through like nothing...im lost on this one folks 98 sucks, i hate using it, would very much appreciate some thoughts on why a previously working OS would out of the blue [considering..] stop working, yet 98 would work fine. I do know xp is more fickle, but it worked while in 98 doing the upgrade install until it rebooted to install from DOS...any ideas pochos?:

 

[Confused]

The most that you can expect from a CPU is the speed at which you buy it at.


Ignore Dan (MrFiTTy), he's been getting harsh on everyone lately.


Does WinXP now install with the CPU at even default speeds? If not, then you should more than likely be able to get the CPU RMA'd, because if it's failing at default speeds, then there's no point in having the CPU.

Maybe this was one of the CPUs that won't even do a very minor overclock, it is possible.

Hey, sometimes peripherals can't tolerate FSB overclocking. My WinTV-PVR 350 doesn't like any FSB overclocking; well, rather, it more likely doesn't like an out-of-spec PCI bus. I put the FSB to 135MHz on a Shuttle AK35GTR board, and the recordings that the PVR-350 made had all kinds of audio pops in them, which increased in frequency of occurance as the file played further; by the end, there wasn't anything of the original sounds audible, just interference. Put the FSB back to 133, and everything was fine.
But if you've got a PCI bus lock, or less fussy components, you should be fine.
I usually will do the multiplier first to see what the CPU's limits are, THEN do FSB overclocking. In my opinion, that should help rule out the CPU as the source of any problems - if it reaches 1.73GHZ by 13x133MHz, it should reach 1.74GHz by 10.5x166MHz. At least that's what's worked for me thus far.

You should post this message in the OC forum. The goons there should be able to answer your questions.

Set the RAM timing to Auto, and set the Vcore to 1.675 or 1.7, and you will be fine. Also, check to see if the PCI divider is set to the right on for you board. If there is no option than it is probably automatic on your board.

 

[peonyu]

ok this is kinda weird, it wouldnt boot when i set the multi to 133x14.5 [19.2ghz], but it will boot if set it to 138x14, which is actually higher than 14.5x133! Im thinking that maybe the board doesnt support some Athlon combinations, just only pre-set combs, weird. Also, i guess i should have mentioned this before but this cpu isnt negative multiplier unlocked, im not messing with soldering cause my last athlon died that way in case any one was wondering why i didnt drop the multi. Anyways now that im fsb oc'n, I dont think i have a pci lock so whats a safe average PCI speed? would 40 do? and about the voltage, setting it to 1.7 wouldnt be dangerous would it? THKS

update: Hit 2150mhz by 153x14.0 V-1.675 temps are 36C, the multiplier above 14.0 DOES freeze it

 

[peonyu]

Ok another question , my temps at 2240mhz are 38C, are these safe for a tbred b and whats the highest temp it can handle? thk YU

update: Switched fsb to 166x13, its now at 2150-XP 2700+! Temps are 36c Vcore=1.625

I would very much appreciate advice on whats a safe temp, I plan on driving this as far as it can go!

 

[Lonyo]

Very highest temp is 85 deg, but keep it below 55 and you'll be fine.

 

[peonyu]

Update; got it running at 200fsbx14.0 speed is 2.80ghz, equivalent to a Athlon 3300 I beleive, only problem is the heat is around 50C now and Vcore had to be upped to 1.750.

http://www.beachlink.com/candjac/index.htm link to Workarounds article, find in Table of Settings that 14.5X Remaps to 21X...there's your answer. Good idea to read other articles as well, like Multiplier Code, and Tbred...get familiar with "your equipment" before you start oc'g it....many other "Remaps".

OK thing about higher Vcores is it lowers the lifespan of the proc alot. I don't know how much. I have a Tbred 1700+ and I got it at roughly 1.6GHz and I haven't upped the Vcore at all. (see my rig link in my sig). Only reason why I didn't push farther was my board isn't good for OC'ing and made my PCI and AGP buses go way too high (like AGP was 75MHz x 4 and PCI was 40MHz, safe is like 36MHz max on PCI - I need an nForce2 mobo!)

Just something to consider about the Vcore
