Upgrade on LGA775 machine?

[TheLaserCucumber]

Hey guys, just got an LGA775 PC from school that they don't Need anymore. It's an Fujitsu Siemens Esprimo E5925 with an Core2 Duo E6550, 4GBs of DDR2-800 and an integrated graphics in the Q35 Chipset. Also it has a 300W Fujitsu branded PSU.

I wan't to upgrade it to an Core2 Quad Q9450, 8GB DDR2-800 and a 750Ti.

My first Problem is, (as you can see in the Pictures below) that this is an SFF case.

It has got this PCI riser Card, in which actually fit dual Slot Cards with normal width, but it's, as said, for PCI.

Now should i try to get a PCIe riser cable and screw it into this metal cover, or should i try to modify the case that a 750Ti would fit in there without the riser?

And yes, i checked whether the fan of the 750Ti would scrap on something on the board, but thats not the case.

 

Second, this metal thingy with is on the PCI riser Card, fixes in with the riser Card. without, it wouldn't be really stable...

 

Any tips?

 

Thanks

You don't have a choice except to use a PCI to PCI-E adapter. This computer isn't worth it man

Intel Q35 chipset - PCIe gen1

GTX 750Ti - PCIe gen3

 

don't waste your money mate, it's most likely the mobo won't boot with a gen3 PCIe card

PCIe is backwards compatible

no it's not with gen1 PCIe mobos

But it will work.

Seen other guys doing it.

might've had the chance the mobo manufacturer updated the BIOS to be gen2 compatible

PCI Express 3.0 Base specification revision 3.0 was made available in November 2010, after multiple delays. In August 2007, PCI-SIG announced that PCI Express 3.0 would carry a bit rate of 8 gigatransfers per second (GT/s), and that it would be backward compatible with existing PCI Express implementations

mate, forget wikipedia and trust actual people who actually put gen3 cards in gen1 mobos - they don't boot

there were even problems with gen2 cards in gen1 slots - PCIe 1.1 is more likely to work than 1.0

 

I'm telling you from my own experience

There is no proof, we cant trust you without proof

proof?! mate... gen1 PCIe was introduced 13 fucking years ago and was quickly replaced by gen2 with greater compatibility

Tested it right now. Took the top cover and the back thingy with all the Supports for PCIe and PCI away, and the 750Ti in the PCIe x16 Slot.

Works perfectly fine, apart from that the Drivers for the 750Ti aren' installed.

 

@zMeul this Thing was build in 2008. BIOS update for PCIe 2.0 or am i just lucky?

then you are lucky the mobo manufacturer actually bothered to implement gen2 compatibility in their BIOS

So then, any tips?

riser cable or cutting out some case parts?

well .. take it all out and do a open bench type system

hacking the thick shell is very time consuming and won't be aesthetically pleasing anyways, nor functional
