Biostar Tpower I45 Reached 675mhz FSB and gave me E8400 WR

[dinos22]

ok i flashed to latest bios >> 618

i can do around 600MHz FSB on air
it can be tuned to perform well but i don't think from what i've seen so far that it will really challenge Asus boards for efficiency
but it's not too bad

one thing that does concern me is the fact that NB voltage is directly linked with vFSB voltage and upping NB will also increase vFSB by the same amount

so when you add +0.5 you are getting 1.52v on vFSB..............if anandtech is right about vFSB killing CPUs your chips won't last very long at all if you put more than +0.5 into NB

My new E8500 E0 on the same mobo, not too bad in fsb but this chip does max 5800mhz under cascade and 1.84v

Tomorow i will test on an other mobo.

Update to 700mhz FSB, Chipset under 4° watercooling









And super pi 1M quickly done

Great job Thomas .

[Maduk]

Matos de maboul

Crazy motherboard

Great men

Fantastic work Thomas, I need to pick up one of these boards

[youngpro]

nice work thomas, efficiency looks not too bad there mate
we just gotta work on mch for system bandwidth a little more..

[dinos22]

haha great photo there dude

Before to get new bios , If you want to assynch vNB and vFSB :

you can use tpower II software, decrease vFSB and increase vNB, that works fine !

[dinos22]

i only have the board
actually i'll probably have to send it back to josh soon so this will all have to wait for another occasion

Which Timings did you use for that 1M run?

[Pt1t]

Which Timings did you use for that 1M run?

5-5-5-15 ... i ll do it again with 2cores.

Cas4 isn´t possible?

[Pt1t]

Cas4 isn´t possible?

Maybe , i havent try. It s my last DDR2 KIT + 750mhz CL5 capable ... i dont want to burn it playing C4 @ 650mhz and high vDimm

[gugle]

the review of newegg, say that the plate bend easily even with the stock cooler, is this true?

[dinos22]

Cas4 isn´t possible?

biostar bios doesn't allow you to select RAM timings if you want high FSB so you can pretty much forget running CAS4 at high FSB

i did somehow (ONLY once) manage to boot at 4-4-4-9 timings at 570MHz FSB but could not repeat it with same settings later on for the life of me
very odd board when it comes to RAM................

[Vivi]

hmm. How high can you set your NB with the linked vFSB? is it 1:1, like 1.5Nb = 1.5Vfsb?

[Eldonko]

700FSB!! Woooooo, congrats !

This is really strange. My RAM will be bored with CAS5

Is there an OVP/Droop Mod out, yet? I´m waiting for this board to be available in Germany but that somehow takes very long...

[dinos22]

maybe Thomas can update everyone on OVP mod
i don't have it handy any more...lost the image

[Pt1t]

Here you have ovp mod , but with this mod minimal vcore will be 1.42v.

[sofarfrome]

there are more bios' here

The 620 saved me from sending the board back to newegg as my pny 9800GTX would not work with the shipped bios. Now it works like a charm.

[Vivi]

Great! thanks for the OVP mod.

Sorry for this dumb Q, but i just solder 1 wire to all 3 to ground? no resistors included?

Thanks and soz lol

good job, nice pics
