I want to upgrade my OptiPlex GX620 (BIOS A11, Intel 945 Express chipset) from the current Pentium 4 630 (sSpec SL8Q7) to Pentium D 930 (sSpec SL94R).
Does anyone have experience with an upgrade of this kind?
Also, what's the difference between 4MB (2x2MB) cache and 4MB cache in the Pentium D 9xx family? See, for example, sSpec SL94R versus sSpec SL95X here: http://processorfinder.intel.com/List.aspx?ProcFam=2112
Thanks for any help and enlightenment!
I have a very similar question. I have a Dell Optiplex GX620 with the Dell 0HH807 motherboard. From what I have been able to determine, this board is using the Intel i945G/GZ rev. A2 chipset. I have updated the bios to the A11 revision.
I cannot tell for sure if I can put an Intel E4700 processor in this board. I know that the socket size (LGA775) and FSB speed (800MHz) are OK. I believe I can put a 65nm cpu in there. The other thing I have been told, though, is to check the voltage capabilities.
I want to use the E4700, but will put in an Intel Pentium D 940 if I can't put in the E4700. Here is what I have found out about the voltage:
- The E4700 V core is specified at 0.85 - 1.5
- The 940 V core is specified at 1.2 - 1.3375
If I am reading the i945G/GZ spec correctly, the core power voltage is 1.5v, with a max of 1.65v.
So, can I safely use the E4700 cpu here? I cannot find anyone on the Net who has definitely done this.
I'm new at this, and don't know a lot about it, and would appreciate any help or advice!
