It seems to be working fine and all i did was flash the bios and plugged in the chip! The previous chip was a P3 500 non Cumine so i know there voltages are differant but no way to change them. Did it adjust it self?
Glad to see this post. Don't know the answer to your question but I have the same Dell 500 system and have been thinking about upgrading to a p3 850. How easy was it and how much of a performance gain did you see. Did the stock cpu fan that was on your 500 chip work with the 850?
If you have a dimension, i'm not too good at those but I know precision workstations... the precision - only certain motherboard revision takes cumine, and it suppose to auto-adjust to 1.65 for cumines but I wouldn't take that risk, rather get a fc-pga and throw on slocket because you'll probably upgrade the computer and could use the same fc-pga on new boards instead of slots. BTW, need bios update also.
I got a jump of about 250 points on the 3d2000 test. Also the stock chip had a heat sink only but the chip i bought had the fan & heatsink & the power lead for the fan. The mb has the connection for it.
Got to go to work.
I'm trying to do the same thing. I have the Dimension XPS T550 and want to upgrade to an 850. Is there anything else I need to do besides slapping in the new CPU? (bios updates, etc). Can anyone recommend a good place to order the CPU's that have a good return policy in case it doesn't work out?
The main problem with using a cumine chip in an older BX board is the cpu voltage requirements. These chips require voltages ranging from 1.6 - 1.75 volts whereas the older P3's used voltages in the 2.0 volt range. Some of these older boards will not support these lower voltages because the onboard voltage regulator will not go down low enough. Using a slotket does not lower the voltage itself it only sends a voltage signal to the regulator and fools the regulator into thinking x.x voltage is needed. If the regulator does not go low enough, there is nothing that can be done. Some of the older boards will go down to 1.8 volts which is a little high for a cumine but not too bad. I would try to find out what the voltage support for the motherboard is before installing a high $ chip in one of these old boards. Another possibility is to try a overclocked C2. Even if the chip is run at 1.8 volts and burns up, not too much is lost. Good luck.
