Suggestions wanted PLZ

First off, im new to the overclocking community, LOL. I just got a new pc (the old one was a 566 mhz celery, 64 mbs ram, 4mb onboard video LMAO). This new pc has a ABiT KD7 mobo, XP1700+ tbred A (AIUGA stepping i believe, d@mn you Newegg, hehe), 512mbs of Corsair PC2700 ram, and running a VisionTek GF4 Ti 4200se (128mb version). First i tried out just changing multiplier. At 133 mhz, i could run 12.5x multiplier fine, almost 1.7 ghz. So i went to 150 mhz FSB, and could run up to 11x FSB fine. Went up to 166 FSB with 10x multiplier, and changed DDR voltage up to 2.7 from the stock 2.5. Still everything running perfectly stable. THEN i tried going to a 175 mhz FSB, with 10x multiplier and my pc crashed while loading windows. Ok, no big deal. I just reset CMOS jumper then reset my pc to 166mhz FSB with 10x multiplier. So what should i try now? BTW, im on air cooling with a Volcano 9 heatsink + fan (yea, its crappy i know, but i was on a budget, hehe). Thanks, any help will be appreciated!

P.S. http://www.zerorecon.net/laggy/not_too_bad.jpg <---those are my 3dmark scores now, running at 166 mhz fsb, 10x multiplier, and video card overcloked slightly to 265mhz core and 475 mhz memory clock.

Could be because that board has no AGP/PCI lock therefore all PCI cards will be running faster. THe KD7 is a KT400 so doesntg have the ability for you to lock the PCI or AGP slot to their standard speeds (33MHz and 66MHz respectively.) This could be causing your crahses. What are your CPU temps? Also, might be worth coolnig the SB passively, doe sthat board have active NB cooling?

My CPU temps are 34 C for surface, and 60 for internal. I've read that the KD7 board gives high readings tho, but i dont know. And yes, it does have NB cooling. I will have to check into SB cooling. So whats the next step i should take in my quest for overclocking? try upping the multiplier a bit? or should i continue trying to raise the fsb, but add a bit more voltage? or just be happy with what i have?? lol

well ur prolly gonna have to get your vcore up to 1.85-1.95 to get much more out of that cpu. 1.95-2.0v is prolly all I would go tho b/c after that you'll just make more heat and prolly no more mhz

try upping vcore and run 11.5x166=1906 or so mhz

about 90+% of the A series tbreds will do 1900mhz
I would say you have a very good shot at 2ghz too. I wouldn't expect much more though b/c most top out between 1950 and 2050mhz with some that are outliers.

By the way, Welcome to the Xtreme! :D

There good temps, I just checked, it has active NB cooling, maybe be a good idea to plonk a heatsink onto the SB, it has no cooling at all, never be happy with what you have! You paid for the hardware, as long as you dont muck it up push it as far as it wil lgo. I usually up my OCs via FSB simply because of the memory bandwidth, it increases it! On those boards though, as you increase the FSB you also increase the PCI and AGP slots. This can re§§§§ in HDD ciorruption sand loss of data. Also, damage to your expansion cards can result. I'd psuh it as lil higher thougf, not sure how much that board wil ltake FSB and no boards are equal so what one guy got you might not get close to. Id continue to up the multi as far as it'll go without extar volatage, extra voltage means more heat but add volatge when it needs i.e. become unstable

Good Luck!

he's fine to about 190mhz fsb before he should even begin to worry about hd corruption
that ram should take it too
maybe up the ram voltage/vdimm to 2.8v too

Just making sure hes aware of the dangers, it would be sensible to back up the data on your hdd if is important ;)

[LaGGy]

Ok i upped the vcore to 1.6v and left FSB at 166. Changed multiplier to 10.5x. Running now at 1.75 ghz now stable. CPU temp went up 2 degrees, but thats not too bad i dont guess. got new 3dmark scores. http://www.zerorecon.net/laggy/getting_better.jpg

[LaGGy]

And no, nothing on this hdd is important. Its a clean install, just got the HD like 3 days ago.

[JNav89GT]

ok 1st off this os xtremesystems.org not fischerprice.com

crank the vcore and pump the fsb :P

j/k, but really I would bump the vcore to about 1.9v and try to get 2ghz 12x166

do it do it do it do it !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

[LaGGy]

Lol well, if i fry the chip im screwed.....hehe.....ill push it up a bit more later......gonna make sure its good and stable right now

[JNav89GT]

:p

ok I guess you have a point. Not everyone wants a dead parts graveyard in their workshops. However, I don't think 1.9v will hurt that cpu. Plus the hardest part in putting the HSF on is already done. Enjoy the speed and max it out as you feel comfortable

Well considering this is the first pc ive ever owned that ive really been able to overclock, itll take some time for me to get used to the limits of the parts. Im gona play around with it, but i would rather be sure everything is stable before i go on to something new. :)

[JNav89GT]

dl prime 95 and run that as well as looping demo of 3dmark

have u optimized your bios yet
b/c ram timings make a big difference

very sensible, i did the same at first but once you get OCin dont expect to go back :D

Hope you get on OK with your PC :)

The problem was too high frequency for PCI and AGP buses. As you know, fsb 175 is high frequency i don't know exactly divider fo your mobo. I think you have 1/5 but im not sure. Your mobo is very good, but you will have problems with running higher then 166MHz fsb. Good way waill be buying other mobo - on the NForce2 chipset - good choice will be SOLTEK SL-75FRN2-RL - on this baby you can run 230 MHz fsb smoothly :)

Your result is very good too :)


Ahhh

If you have your entire CPU code written down, go here and enter it; http://mp3.zonebg.com/cpu/cpu.php
If you do not know the entire code, next time you either change your HSF, or are just curious to investigate the job they did installing your CPU, remember to write it down. Some may criticize me, thinking this a tedious (possibly superfuous) task, however; when learning to overclock, it's critical to know exactly what it is your overclocking, i.e. stepping, date of production, possibility the processor may be downgraded/upgraded. This will not only increase your knowledge of AMD's CPU code, and it's significance, but will introduce you to the production process, expanding your knowledge much further.

The code on your AMD (or Intel) provides crucial information. And the same applies for your memory. When you begin getting into overclocking your Ti4200 (which will increase your 3DMark2001/2003 scores) you'll understand the identifying of microchips is crucial. Your VPU (Visual Processing Unit) or GPU (Graphics Processing Unit) your motherboard's NB (NorthBridge) South bridge, your memory (DDR), the memory on your videocard; these all have steppings, and codes on them which allow you to immediately identify them, determining their voltage, and frequency (speed or MHz, etc.) all valuable information. And finally for overclocking your videocard, the following link will bring you to program known as Powerstrip 3.30. I've linked you to the download page. Simply follow the instructions and you'll have one of the most effective videocard overclocking programs out there (perhaps the best, in the opinion of many). By the way, once you install Powerstrip, and it's icon is on your Taskbar (after you wait for it to load and click close on the frist window's button asking if you want to "read more tips"). You open the overclocking portion by right-clicking on the Taskbar tray Icon (looks like a tiny monitor) and will bring up menus. Go to Performance profiles, and left-click on Configure. this will bring up the "sliders" which will allow you to overclock your Ti4200's "Core" (GPU), and memory. Try to keep it under 10% of the total default speed (10% of core/mem) to be safe. Here's that link; http://www.entechtaiwan.com/ps.htm
