Please help me overclock 700to933

[rcueto]

Hi everybody, I'm new at this forum, a guy told me I could find some help in here.
I have a PIII700 Socket 370 FSB 100mhz with a Asus Cusl2-C, and 128Ram PC133 memory (Markvision, personally I've never heard of it before, lol)
I've tried to clock it to 933 but I will always have probs when trying to boot, and if it boots apps are really unstable. I thought back and realize maybe the cheap ram could be the problem, since its supossed to be PC133 and my bios says its just cable of PC100. But I have one reason why this may not be the prob, I set my FSB ratio to 133:100:33, were ram is not being overdclocked, either way its much more unstable this way (strange):confused:
I dont have a really cool cooling system, but I don't think thats the prob.
Any ideas, suggestions

thx in advance

Welcome to the forums!!! :) Your friend has certaintly pointed you in the right direction. If I can't help...(which happens a lot still!), someone else surely will.

I'm not sure what options your motherboard supports but are you attempting to raise your voltage at all? If you have a stick of 133MHz memory then that is most likely not your problem unless your using fast memory settings (CAS2 instead of CAS3).

What kind of motherboard are you using? If your using stock cooling, a voltage increase will most def. increase the heat output of the processor so you should keep a very close eye on temperatures if you plan on increasing the voltage. Or better yet...buy a good heatsink/fan setup.

I have a H/F from Cooler Master the "DP5-5G11", not the best one, although I think its enough,my temp go from 32 when idle to 50 when Full Load. I currently have a cheap thermal paste, bought it at an electronic shop. About case cooling I've got just the power supply fan and an extra Pci fan below my voodoo5 graphics card. I think its enough, although I've run my Comp without the case cover, and it still crashes.
Actually when I put CAS2 My comp will just not boot, so I have it at CAS3, as I sayed, its supposed to be a PC133, but my mobo says it a PC100 ****ty, so I'm starting to belive what my mobo says, lol :p

A guy told me my proccesor uses stepping cB0 and it can handle the 933 with the defaut voltage, so I've had change it and also used the default voltage, but the prob continues the same way.
I have an Asus Cusl2-C mobo, people say its a pretty good mobo, it supports 66:100:133 FSB, so I really doubt its the problem.
I'm currently running @847mhz when I bump it to 875 it crashes, since the PCI is to overclock I think. So I changed the ratio to 133:133:33, so it will just boot if the system has been for a long time off, when it boots succesfully, windows runs perfect till I start to run apps like 3dmark or games, the apps just quit, until someday it crashes.

You have a great CPU and motherboard. Your RAM and heatsink/fan are only average.

HOWEVER... you are having major heat problems. Anytime your CPU load temps go above about 45 degrees when you overclock those coppermine CPUs, you're asking for instability. I have a P-III 700 and with my cooling mods, the CPU load temps rarely ever exceed 40 degrees, even when overclocked at my normal 1050. Take some time to get your cooling straighten around. Once you have better cooling, then you might consider raising the CPU core voltage a little. Do the cooling first though, trust me on this one. I've been there, done that, and have the T-shirt to prove it.

rcueto-

1. Better cooling can only help. IMHO, one of THE best HS for that rig: http://millisec.safeshopper.com/53/301.htm?793

Modify it like this for socket use: http://www.overclockers.com/tips245/

Decent cooling, moderate noise: http://millisec.safeshopper.com/52/442.htm?793

Noisy, but much stronger: http://millisec.safeshopper.com/52/385.htm?793

2. What BIOS? Try here for a ton of help & BIOS info: http://www.asusboards.com/forums/index.php?s=

3. If you haven't done so, try bumpng your vCore.
I wouldn't go past 1.85V with your current cooling setup, & probably wouldn't run it there long until you've improved it.

3. You can try setting your FSB/RAM to 133/100/33, CAS 3/3/3 7T/9T Normal.
If it runs at 933+MHz, try going with 2/2/2 5T/7T Strong, then increase it to 133/133/33.

4. If you do get it to run beyond 140FSB, you'll want to use the tweaked BIOS, Stuffpcr or WPCREDIT to get your performance back.

The BIOS will automatically throttle back RAM timings and drop AGP to 2x above 140FSB regardless of settings, so those tweaks can make a BIG difference.

5. There is also the "cold boot issue." Do a search at the forum linked above for full details, but basically-
A. The board will cold boot at default vCore, regardless of BIOS settings.
B. If you have a "reluctant" chip that needs more than default vCore to cold boot at OC'd speeds, you only have a couple of choices.
C. You can cold boot past POST, hit reset & warm boot, OR
D. You can do the "wire trick."

IMHO, chips are cheap enough now & the yield has improved to where it's probably a waste to do the pin trick, except in certain circumstances.

This article is pretty old, but it touches on the issue & also has benchies of a cB0 700 at 980MHz to 1015MHz: http://www.dalantech.com/asus-cusl2.shtml

The memory tweaks alone are worth +10%-+15% at 155+FSB speeds...

Good luck, hope this helps! :)

hi everybody, A friend of mine bought some thermal compound and I will like to know if its a good one, its named:
"NTE Electronics Heat Sink Conpound, Thermal compound, 1 gram/tube" thermal grease"

I have just heard of Artic Silver, so I ont really know if this is a cheap one or good one. About 4 months ago I bought a really really really cheap one, lol and I had to pay for my sin, since my Cpu went a few degrees up instead of getting cooler. Actually it wasn't that cheap ($) but it was available at my electronic shop near my school.

This (http://www.svcompucycle.com/thermalgrease.html/) place has the best price on ASII and the best price (http://www.svcompucycle.com/thertakgolor.html/) on an Alpha PAL HSF combo.

If you're gonna spend $$$ and the effort, why not go for a proven combo?
