Dellmantt, do you really have a core 2 duo or is it a dual core? On dell page specs this mobo cant use a core 2 duo http://www.dell.com/...t...cs=22&s=dfh
I'm thinking to upgrade my cpu but i think that the best processor this board suports is a Intel Pentium D 960 (Dual Core) 3.6 GHZ. Is this true??
Thats funny Dell have changed that page (I have it bookmarked). It use to say 'The GX520 comes with 3 processors an intel® Pentium® 4 dual core, Intel® Celeron® D & Intel® Pentium® D", which is what I quoted in the guide. From what the site says now the Pentium D dual core seems to be the fastest option. I am wondering now about the accuracy of the page as further down it now says "Available DIMM Slots:Two Memory slots offering up to 2GB". It used to say 4GB, which I have. Maybe it is the wording and it means 2GB per slot, From memory the old page said for the CPU
Pentium® 4 dual core -single core 2 threads
Intel® Celeron® D - single core single thread
Intel® Pentium® D - single core single thread
I would be checking with Dell as to what processor your board can actually take. In another thread, that I now can't find, somebody tried to upgrade a GX520 from a Celeron to a P4 and could not get the computer to boot.
Interesting, From http://en.community....t/18290488.aspx
"Thank you for using the Dell Community Forum. The OptiPlex™ GX520 system supports the Intel® Pentium® 4 (Prescott) 5xx series and Pentium 4 Celeron® 3xx series processors.
Beginning March 17, 2006, the GX520 also supports the Intel Pentium D (Smithfield) 8xx series processors."
From the same site "I emailed Dell Tech Support and they have told me that the Pentium D is the latest CPU that will work in this system. Here are some compatible sSpec numbers: SL88T, SL8CP, SL88S, SL8CN, SL88R and SL8CM - these are all from the 820, 830 and 840 range (no 9xx range will work)"
