I have two Retail 1.0A Celleries. All of these test are with a BE6 ver 1.2 upgraded to 2.0 with BIOS hacks that also allow the Tuallies to be id'ed. An Alpha PEP66 w/ Delta 38 provide cooling. 256MB of Micron memory know to hit 156 CAS2 on a KK266, and a Retail 8500 64MB for video.
One is a Philly chip, that at 1450 and 1.70v hits 41c-42c under prime 95. It's dated week 36 of 2001. It cannot hit 1500 without 1.80v, and it's really pushing it at that.
The new one is a Malay chip dated week 11 of '02. It hits around 46c at the same speed as the above chip, yet it can hit 1490 at 1.70v. It gets farther easier than the Philly chip, but it just runs hotter.
So this is what I figured. The heat shield on the Philly chip was put on better (runs cooler), but the silicon is worse because it can't hit as high with lower temps.
The Malay chip has better quality silicon, but because the IHS was put on badly at Intel, it runs hot.
So I decided to pull the IHS off of the Malay chip. This went successful, but I can't seem to get the chip to cool properly. Putting an Alpha PEP66 directly on the chip gets me to the 60's. using the IHS as a shim to level things out doesn't work either (high 50's).
So now that I've already done it, how do I cool this tiny cpu?
Some interesting tid-bits:
Running at 1500, I'm getting 8300 3dmark2001SE. My XP in the KK266 running at 153*10.5 = 1600 only gets 8000. I am really interested in keeping the AGP at 100MHz. Even at 2x, the true throughput is what counts. I'd even go for modding the BIOS on my KK266 to prevent the AGP 1/2 divider from kicking in at 133.
Running the Tually at 66*10 (667MHz) at 1.4v, using my finger at the heat sink, it gets as hot as a soldering iron within a few seconds. These chips are really hard to keep cool because of the small form factor.
How about this: If I mill a hole in the copper of the PEP66 so that the HS sits flat on top of the CPU, and the core sits flush inside the recess?
Does someone know the heat output in watts of a 1500 tuallie?
HELP! before I go crazy. I've always had good sucess overclocking (550E running at 853, 933 running at 1120, XP 1600+ running solid at 1600). I see a lot of prople hitting 1600 with these tuallie chips. I've had 3 (the other was a 1.1A for a friend with good markings), but none have been able to break 1500 without extreme measures. I'd really like to hit 1550 with a 1.0A on my BE6-II. Is this asking too much? Am I at the end of the line with these CPU's?
Thanks for the help.
