Finally!! Celeron600@900Mhz!

[Joe Conflict]

After much tweaking, i FINALLY got my 600 to o/c @900 (boxed SL4NX) . Abit BH6 v 1.0 w "SS" bios, Iwill Slotket II adapter and aftermarket heatsink/fan running @89f(corection from "c"posted earlier) . I do recommend sanding any anodizing off of the bottom of any heatsink/fan combo before mounting on your chip, as it will prevent proper heat transfer, and any added fans in the case (running mine without cover) are helpful too. Found that the Iwill adapter needed to have jp6+jp7 jumpers removed or the chip woulodn't go past 66mhz (133 clock setting) 3dfx Voodoo 3000 video, 128mb 8ns PC 100 ram

This goes to prove that all cC0's are not as wonderful as people make out.

If you burn it in some now, you may well achieve a better speed soon such as 927Mhz or 945Mhz. Go get it!!!!!

You're at 89C? Yikes!

If Celerons are just PIII's with bad cache and lowered bus speed, why is it still slower than the real PIII's, even when o/c'ed?

Btw Joe, at what voltage is your Celeron running at? I have a cB0 Celeron 600@ 900Mhz runnin at 1.9v my heatsink is warm to touch.. about 103F i guess, i don't have a temperature measuring instrument. It's winter now, so i don't know how well it'll perform in the summer.

One reason is that you not only lose half of the cache, the 8way associative mode is not possible in the reduced cache and it runs at 4way. This means that the data the cpu needs only has half of the chance of being in the cache, and therefore will take more clock cycles to utilize or acquire it. Also the cache latency is set to a higher value in the celerons- 2 vs 0 for the PIII if I recall

Cache is the key- that's why the AMD chips are performing so well- they have more cache.

Sorry, I meant "f" . no warmer than my previous 366 I was o/c before

I'm running 1.85v on a BH6 V1.0 mb with an aftermarket fan that I sanded the anodizing off of the contact surface and finished sanding with 600 grit, then mounted with a small amount of radio shack silicon heat sink compound. I think removing the anodizing is crucial to proper heat transfer to the heat sink, but I wish I had the same heat sink unsanded to test and verify that.

I am also running cover off with the power supply fan blowing right on the heat sink area, and another 4x4" box fan removing the heat away from the area at the top of the case

Hopefully I will be able to push it a little faster after getting a new mobo (BX133 RAID planned soon), but for now it won't even let me go past 100 to 104 (turbo) as it stops at a windows GPF while booting now. I'm probably pushing what I have now to it's limits.
