Avoiding the $100 Tualitin screwup

[dustybyrd]

Re: You Guys are great!

I love all this advice!

The limiting factor on overclocking the Tualerons is the Intel D815EEA's fixed buss speeds of 100 or 133Mhz Front Side Buss. Thus, overclocking the Cel-T is a 33% (by insulating the BSEL pin) or stock proposition.

If I got the the 1.2 Cel-T to run at 133 FSB, the 12% Mhz advantage over a 1.4G PIII-s should balance out the approximately 10% speed advantage the the PIII-s has over a Cel-T of the same speed. The 133 Mhz FSB is important to me because I can't run the memory asynchronisly, and the PIII's memory bottleneck is the second disadvantage it has over the the P4. The first, of course, being the absolute megahertz limit.

I see on the Database that only 1 1.2G Cel-T with a S-code of SL68P or later didn't make 133 FSB, and 4 actually made it with stock voltage! I also notice that those are all Phillipine chips. I suppose with the prices as low as they are, I could gamble, and then order a 1.1Ghz Cel-T if it doesn't work. All of the 1.1Ghz Cel-Ts made 133 FSB (at least), but only 2 people ran stock voltage.

i have overclocked ~10 tualatins (6 celerons and 4 p3's) and 2 celerons hit 1.6 and the 4 others hit only 1.55 (but all required 1.63 volts or more)...

i think that getting a 1.2 is worth the risk to hit 133...but only if you do voltage modification....you will almost for sure need more volts...

as long as you can sell the 1.2 or trade for a 1.1 then get the 1.2 first and if it doesn't work go for the 1.1

you might be able to place a wanted add and look in the classifieds for a 1.2 that does 1.6 ghz that someone will sell you...

definitely don't get the p3 unless you need the extra cache for programs like seti....or unless you want to run a dual processor...

I still have the PIII866 running 145fsb on my sons rig...I cant say that day to day use there is no big difference. Yes I can only keep my celly stable at 135 but I can't feel the difference...But like I stated....I can get much better 3dMark scores with the celly running at 135fsb than the PIII could even dream of reaching.

SmokinR6, are you running your Cel-T at stock voltage, did you change the voltage in BIOS, or did you wire wrap the VID pins? Unfortunately, the only way I would be able to change voltage on this Intel board would be the vid pin wrap modification. With a tB1 stepping SL6RP (if I should be so lucky) I could only do 1.5 volts stock, 1.6 volts with vid1 and vid2 connected, or 1.65 volts with vid0, vid1, and vid2 connected. I'm not scared to do it, and the vid pin mods kinda defeat the purpose of using the adapters, unless you have a different reason against doing the three pin plus bridge trick.

I noticed the package2you adapter doesn't allow for jumpering the FSB speed, so if I went with an adapter, it would have to be the Powerleap Neo-T or the Upgradeware 370GU . I suppose I could get the Package2you adapter and do all the pin modifications on it, as it would be cheap enough to not worry about accidently breaking off BSEL1, and the processor would still be unmodified.

New shopping list!

1.2Ghz Cel-T $45
Powerleap adapter $25
Vantec Aeroflow $25 (or should I go with the Zalman CNPS6000 AlCu?)
Arctic Silver 3 $ 6
Total $96

I suppose I could still use the rest of the stuff if overclocking the Tualeron doesn't work.

instead of wrapping the pins you can also just use speaker wire to make a U shape and put them directly into the socket on the motherboard...i did for my dual system...this is easier than wrapping the pins IMO and both are reversible....

i don't know about the Zalman...but the vantec aeroflow is amazing and is very very quiet...

if you need a vid card i might beable to lend you a GF2 or an ATI RFP that can O/C great (see sig). You can give it back when you get a new vid card PM me~Alex
