Doing Linus's old Xeon thing for cheap, HELP!

[Minhee108]

I want to do the $150 Xeon build on Vessel right now, but I dont know if these motherboards have PCI-E 16x slots, can someone help?

Thank you.

Neither of them does.

Doesn't even have PCIe

 

The Dell has PCIe

Thank you.

The Dell has one.

the first one does...

do you have eyes??

I thought they were AGP and PCI from a quick glance.

I admit I am wrong.

Thank you.

 

if you go for a board from a Dell Precision T7400 it comes with two PCIE x16 Gen 2.0 slots (they dont support SLI and are also quite close together) you will also be running the Intel 5400 chipset - this chipset supports 400mhz FSB chips.

 

 

If you buy a 333mhz FSB chip (eg e5450 / x5470) and put in a 5400 chipset board - it you can do a quick mod with stickytape to get an extra 25% clock speed out of them. 

 

 

FYI the T7400 also has a few "options"

 

you can get a ram stacker - for huge ramz

 

 

you can get an SLI addin board for SLI

Is the mod just putting the sticky tape over the one pin and is there anything that could go wrong(Murphy's Law is incredibly true for me)? Also just making sure (can't be too safe with a strange build like this) would this board work with a pair of X5460s?

there are always things that can go wrong... use care. there is no more risk than whenn normally installing a CPU.

 

be extra careful to ensure no other pins are covered over with tape. make sure the cpu is seated carefully in the socket - the tape will make this trickier than usual.

 

As long as the chipset on the motherboard is the Intel 5400 chipset (dell t7400 uses this chipset) - it will work. and the X5460's are the second best chip to do this mod to, you will get 3.8ghz out of them. (the x5470 being the best and reaching 4.0 ghz with this mod)

 

I am not 100% sure that they will run at stock voltage when running that high a frequency - it should be ok... worst case it just might blue screen and you can either up the volts or revert the mod - there are further (more permanent and complex) modifications that can be done to the CPU LGA to overvolt them significantly by tricking the motherboard into being told the wrong VID - this is the predefined "normal operating voltage" that tells the motherboard how many volts the CPU will need. NB: the attached image VID table will not work on your CPU.

 

to increase the FSB from 333mhz to 400mhz - the pin you want to cover in BSEL1 - see the below diagram - its pin H30 - its the bottom row on the edge with the little socket notches. and it will leave 6 pins to the left un covered. notice that the rows 27-30 do not have a pin in column A. 

 

when I did mine I actually covered G30 - this didnt afffect anything and it just loaded normally and I then removed them and fixed it by moving the tape to H30.

 

 

 

to explain this mod - basically the CPU uses either open or closed circuits to tell the motherboard what front side bus (and what voltage (VID)) it wants to run... by covering H30 you are opening an otherwise closed circuit - if you were to install a CPU with a 400MHZ FSB (X5472 for example) this configuration of open and closed circuits would match that of your now modified cpu. Therefore its 100% safe - the only downfalls will be portentially damaging the CPU when handling it, or damaing the CPU socket when installing the CPU - these are no different that when normally installing a CPU.

 

NB: some motherboards may also need DDR2-800 ram to work, others (like the t7400) will run DDR2-677mhz ram on a ratio divider and cause no issues

If I were to do all these mods do you think that it would outdo two x5570s running at stock speeds?

5570s? Hmm probably not. If you go 1366 try and invest a little more in the 6 core 32nm cpus.

Maybe for games the 5460 modded would be better than the 5570s? Not really sure.
