First overclocking attempt - Opinions needed
I've been debating overclockig my P2/266. I've read the various FAQs and tutorials here and on other sites, so I understand the process and how to go about it. What I'd like to know is what kind of experiences you've had (good, bad and weren't sure until you solved the problem) with any of the other equipment in my system:
Asus P2B (purchased when the board first came out, flashed BIOS to 1006)
P2/266 SL2HE Philippines (never understood the theories behind o/c success, country of production, SL-whatever codes, etc...)
single fan heatsink (can't find a brand name on it) connected to the MB fan power connector
2 case fans (also no brand) connected to power supply, both fans mounted to blow air out of case, one at front bottom, one at rear top about an inch from processor
ElanVital T-10AB case
ATi All-In-Wonder Pro 8m AGP
Maxtor 8.4G HD
SB Live Value
USR Voice/fax modem (ISA)
Storm EasyPhoto Drive (uses ISA card in addition to 5 1/4 bay)
Creative 24x CD-ROM
External Zip and Ditto drives
I'd also like to use the 100 or 103Mhz FSB for this O/C attempt, as using 75 or 83 will run the PCI bus at 37 or 41, rather than the normal 33. If I'm going to fry something, let me only fry ONE thing. This will make my possible O/C's 300/310, 350/360, 400/412. Opinions please?
SL2HE is a 2.8v version P2. Most 2.8 P2 will OC to a 75 MHz FSB but not very stable.
I got a p2 266 (SL20B, Malay)...and it's running fine at 350....well it hangs very occasionaly in half-life when hell breaks loose. I'm also on a asus p2b, and I think I have crappy pc100 ram. Anyone want to tell me how to increase the voltage without buying a bh6?
oh yeah...mine is 2.8 too
I have a P2B and was also running one of the older PII 266. If you're lucky you won't have any multiplier lock (if its a way old CPU). If you're kinda lucky it will have an upper max at 4.0X multiplier (Thats how mine is...I can change the multiplier lower, but not higher than 4.0X) If you're unlucky, you'll be stuck at 4.0X multiplier. Assuming that you have PC100 memory, the best way to go is sticking to the 100Mhz bus speed. (no overclocking of ISA or PCI.) If you have either 1 or 2 type of CPU this will work (probably). I'd suggest changing the mult to 3.0 and the bus speed to 100Mhz. My 266 would do this just fine. (300/100) Then you could try 3.5 mult and 100Mhz for 350Mhz, but mine wouldn't even think of working at that speed. I also tried 3.0x and 103 for 309mhz but it locked up from time to time so I stuck with 300. If you don't have PC100 memory, and your PII 266 isn't max multiplier locked, then you could stay with 66mhz bus and bump up the multiplier to 4.5 for 300mhz (go ahead and try, if its lock, then your system probably won't boot, you'll then have to lower the multiplier again) and you can go up by .5 increments until you hit your fastest stable speed. If you're unlucky and are clock locked at 4.0X, then you'll have to mess around with the 75Mhz and 83Mhz bus speeds. I had a lot of luck with them, but some friends' machines didn't like the OC'd PCI and ISA buses.
And to the guy who's trying to change voltage on the Asus P2B MB. I've done that too (currently running a PII 333 @ 500 and a C300a at 504 both @ 2.4v... . In order to bump up the voltage you'll need to either tape, paint, cut, or otherwise isolate a few of your pins. I'm using electrical tape, but I've been told not to because eventually the adhesive might leak out and damage something. Oh well.
