My 3800++ 2.6 need vcore 1.525. Do u try vcore around that??


-pWs-

yup..i did..i played with vcore around 1.5 - 1.55..but still below than 1.6v..scared la to out a vey high voltage with my not-so-good heatsink..

So 2.6 still failed??? Do u add the vdimm to 2.2V and try again???


-pWs-

managed to get onto window..but bsod appear when in full load..
2.2v vdimm?hoho..scared oso..anyone here put 2.2vdimm with biostar tforce 570u?

My ram now is running at 2.2v
I think it is the same as you right??

BSOD appear when full load, what vcore u using???


-pWs-

ok, lets say that ur proc default speed is 2.0...
when u OC to maybe 2.2-2.3-2.4.. cold boot won't happen...
but when u reach about 2.5 or higher.. cold boot will happen...
meaning, when u reach the maximum OC capability, cold boot will happen...
coz sometime people think that the vcore is not enough but still if u add the vcore, still cold boot...
i also dunno why...

maybe u can try changing the ram timing.. but i think the cold boot will still happen...
also dunno why...

u can try to tweak somemore laa... maybe u'll be able to break the cold boot...

sempronic tried it a few times still cold boot... but after he change from x2 3600 to his present proc x2 3800.. no cold boot...
running stable @ 2.7ghz... summore can go to 2.8-2.9 i think...

2.2vdimm?? why my mobo(biostar TForce 570U) vdimm max till 2.1v oni

i think maybe ur proc limit oc to 2.5Ghz.. try change the proc and see how??

If not mistaken, newer revision of TForce 570U supports higher vdimm.

interesting news... any source about it?

I heard it from davidletterboyz. He is using it now.
vdimm supports until 2.4v if not mistaken


-pWs-

yeap yeap, Tforce 570U Rev. 5.x supports up to 2.4V Vdimm. Sensor reads 2.48V.

But then this revision has one stock BIOS only....cant run DDR2 667 divider....

mean only support 800?

owh.. that y mine vdimm till 2.1v oni...

lucky my Kingston 667 with hynix chipset can do ddr900 with no problem at 2.0v

It's written on the box.
Even if your mobo is not rev 5.x, u still can go up to at least 2.2V. Check your manual.

8tvt, i mean the BIOS is a bit crappy. If i set DDR2-667 divider, it will run at the same speed as DDR2-533 divider.

hi guys, wanna build up am2 rig next week.
i just wanna ask which model of biostar mobo should i choose.
in terms of stability n ocable, and the price too.. thanks

Tforce570U (since david mentioned that it provides up to 2.4V DRAM voltage)

i also face a same problem with u

2.5GHz @ 1.45v
ram 1GHz @ 2.0v.timing set to AUTO
mobo T550
can pass Orthos more than 3HR and 32M super PI

en soulfly..between infinity 570U and tforce570U..which one u recomended???
BTW went to LYP yesterday..almost all shop closed..only open back on thursday long...chinese new year holiday..

infinity 570u provides up to 2.5Vdimm and two pci-e 16x slots

but tforce570u uses solid caps around cpu socket area

but i'd go for infinity i guess

@mr_habuk

do u plan to change mainboard without reinstall windows XP?

Use sysprep utility will lighten the workload
