Thanks

I'm running one SATA atm, so I won't push it that high .

[fatguy1992]

I have one more question.

I can't seem to get 3.7GHz (465x8) to load windows, but if i keep all the settings the same and just change the fsb to 475 (3.8GHz) it works fine. WTF. How can 3.7GHz not load windows, but 3.8GHz with the same volts can run 3D Mark 06 etc.

Thanks

Ever heard about 'FSB Black Hole'

[fatguy1992]

Ever heard about 'FSB Black Hole'

Yeah I while ago. But someone on a different forum told me it was only on Nvidia mobos?

Well I guess it must be on Intel ones too .

Maybe this is why 4.2GHz never works.

[1nsane]

Here a new result in lowering my board voltages for the 510 FSB.



will make a full custom fft run soon

[Solid Snake]

Hi friends.

I have a problem with the FSB of my Mother Board

this is my setup at the moment and I can not climb over the FSB.

[1nsane]

don't set termination and pll voltage @ Auto This will kill your CPU and/or Board.
Try to set everything manually

[voigts]

You haven't mentioned what CPU you are using.

Assuming you are using an E8400/E8500, your CPU may not be able to handle 4.68ghz at 1.45v Vcore. Try putting down the multi to 8.5 or even 8 and then tweak your voltages. Your MCH core is probably higher than it needs to be. I couldn't boot at 500fsb to save my life at 1.4v, but it runs all day at 1.3v. At 530fsb, I just needed 1.32v MCH core. Some other people posted this also, which is why I lowered mine and that solved the problem. Also, your Dram voltage looks kind of high. My OCZ Ram runs at 1066 at 2.1v just fine. Manually set your CPU PLL to 1.5v. I have my CPU termination set to auto, and the same voltage that auto sets is the minimum voltage needed to boot if I manually set it.

[Ghostleader]

I got my E8400 C0 stable with FSB 550



575 was only stable with 1M, fail 2M.



Somewhere between 550 and 575 I probably have my max FSB, no more E8400 for a while, time to test my Q6600 GO

[dccmadams]

pci express , set to 100. i have system mem multi set at 2.00d

[BuGjAE]

Nice OC Ghostleader 550 FSB is impossible for my ram ,Could u try to lower Cpu termination see Is it still hold stablility?

[Rattle]

pretty happy with the ud3p, i bought it as a backup, I cant for the life of me get it stable at 500+ though, i know my other hardware is capable....

it will do 475 on stock volts, I am probably missing something in this bios somewhere...

it will run small FFT all day at 500 but as soon as I go blend CRASH, I cant figure it out. My ram is good close to 1200 and my cpu can do 550 easy...

this chip and ram did 500 on a rampage formula with 8, 8.5 and 9 multi's at 1.18 vtt, 1.55pll and 1.31 NB, cpu volts 1.2 for 4ghz, 1.28 for 4250 and 1.36 for 4500 all blend stable for 12 hours or more...

[ezaleina]

My 535x7.5 result..only can run 1MB PI.,fail with 32MB PI..i dunno why..

[BuGjAE]

Cpu termination may be too low I think up to around 1.26 'll help you

[ezaleina]

Cpu termination may be too low I think up to around 1.26 'll help you

ok.,i'll try later.,but if i increase the Vtt the cpu reference will auto increase on the same time.,is it ok or do i need to set it back to default (0.760)?

[Shiranui Gen-An]

I grabbed a UD3P yesterday from Micro Center for $149, right now I have it paired with my E6300 and 2x1GB CSX Diablo DD2-1150 (D9GKX). Looking forward to posting some results!

[SpeedEuphoria]

You just leave it, but you may need to adjust the references up or down a step or 2 after the VTT increase to find a new sweet spot

[BuGjAE]

Yes, Set VTT1.20 and MCH ref to 0.68 as you set it before, then go raise up VTT to 1.26 you 'll notice MCH Ref will auto increase It doesn't matter. Go and check in ET6 you 'll see it still 0.68 in Windows because it just a Ratio of Vtt and MCH Ref only.

[ezaleina]

ok bro.,i understand now.,just try increase the Vtt to 1.26 and cpu ref to 0.688-0.712.,the problem now is i cannot successfully log into windows.,the system keep BSOD with IRQ less or equal..

[BuGjAE]

I see you running RAM PL8 try to increase MCH core around 1.38-1.4 may be help. If cannot pass you need to run PL9 test stability, and also try set this

CPU Clock Drive...........................: 800mv
PCI Express Clock Drive...................: 900mv
CPU Clock Skew (ps).......................: Auto
MCH Clock Skew (ps).......................: [150PS] <----This can help stablity while using High FSB

What strap are you using? Try "D" it can be relaxing your ram timimg more than "B"

Anyway If it's still can't boot let post your Bios setting

[Jsunn]

radaja,

Can you please post all of your setting for your second rig?

RIG #2/ EP45-UD3P / E8500 eo / G.skill pc8800 / Radeon 3870 / Antec 550W / True120 / Case? /

This is pretty much the exact system I am building.


Thanks for your help!

You sure its not your memory's limit? Did you try 2.0D? or Performance Enhance on "Standard"?

[ezaleina]

I dunno about my ram limit.,but before this already try at 1300mhz PL9 without problem.,also try with Standard performance enhanced still the same..
