Dimension 5150 processor upgrade problem
I have a dimension 5150 bios A07 windows 7. Im trying to upgrade the processor from P4 3ghz to a P4 3.8ghz (SL7Z3),but when i boot it up i get incompatible processor press f1 to continue so i pressed f1 and all was fine,the problem is the processor is only running at 2.79 ghz ,system bus 797mhz.
I have used intel processor identification utility and cpuz which give the same results, im at a loss now what is causing this and how to fix it.
Any help to fix this problem would be most appreciated.

I have an E510 which is identical to the 5150 (the only difference the E510 was only sold in the US and the 5150 was sold everywhere).
I'm surprised that it even works, let alone the "incompatible processor". The Dell implementation of the Intel Chipset is not the full impementation that is available - you are limited to the Dell custom implementation. The Intel listing for this chipset, which supports Dual P4 processors says it will accept up to a D960 CPU however the Dell implementation limits that to a D945 (we have documented cases on the old Dell users forum). Another issue is that Dell used several different part number motherboards and with compatible CPU's on all the motherboards except the 0HJ054 part number board, even if you install a fully compatible upgraded CPU you wil still get the Incompatible CPU and will have to press F1 to continue (and it will work OK). The clock speed of the processor is limited by the Dell custom implementation and the BIOS which does not allow overclocking.
You will do just as well to reinstall the original CPU and try to return the new one.
I upgraded my E510 from the original D805 CPU to a D925 CPU and to be truthful it was a waste of $$. I have the 0HJ054 motherboard so I don't get any incompatible CPU notices.

Thanks for the reply.
I dont think i explained myself very well,the processor im trying to upgrade to is a P4 670 3.8Ghz as suggested by shesagordie in an earlier post,not a Dual P4.
Here is the report from cpuz on the processor if thats any help.Please bare with me as i have little knowledge when it comes to processor,as you have probably noticed.

I don't have that much knowledge either but the problem I see is the 3.80GHZ version, and possibly the part number motherboard you have that will give you incompatible processor.
Maybe Bev will chime in with more info.

If this is any help...It appears that if you have one of these boards (of course this is eBay research :emotion-1: ):
RD203,KF623,J8885,WG261
Then the supported processors are:

Be careful, Intel lists what the "Retail" chipset is compatible with. Dell uses a custom implementation and not every CPU that Intel lists will work in a Dell motherboard.
I have the 0HJ054 motherboard, which was the latest (last) motherboard used, which does not give the "incompatible CPU error" on compatible CPUs, and it won't support everything that Intel lists. The Dell motherbords are Dell custom models (many made by Foxconn for Dell).
