error10

Well now I think it's the USB stick. It started randomly throwing I/O errors tonight.

I'm starting to get disappointed with this board.

I could get my e7200 3.6ghz 1.32Vcore stable for 2 hours with OCCT on my Asus P5K/EPU.

Now i cannot even get it stable for 2minutes with 1.344Vcore

High temps with IBT are common and 60C is not that high but try to lower your vCore as long as you are stable.

You can try to lower your PLL, CPU Term and MCH core, lower one at the time and in small steps and retest for stability after every change until you are happy with it.

You run 4x1 ram and it puts a little extra strain on the system that you most consider and because of that you might not can lower your CPU Term and MCH core that much.


With 8x500 you get some what better performance then 9,5x422 but then again what´s you goal with your OC.

My suggestion is to settle for 450 9 4050 1080 555 15 tRD8 or 9, it´s not an over the hill OC but it´s a pretty good 24/7 setup.



I know the feeling, this is my first P45 chipset board and it seems like it´s much more sensitive then the previous P35, X38 and X48, it took me a while to figure this one out but I´m still learning.

Please post your BIOS setup, that way it can be easier to help you.

515FSB X 7 = 3605MHZ.

CPU Vcore: 1.343 (it drops to 1.31 - 1.328 during occt mixed test )
CPU Termination: 1.34V
CPU PLL: 1,61v
CPU Reference: 0.760

MCH Core: 1.34v
MCH Reference: 0.708
ICH I/O: 1.50v
ICH Core: 1.10v

DRAM Voltage: 2.000( according to my ram )

I think that it´s your 4x1 ram together with that low default FSB of yours CPU that´s need higher CPU Term, MCH Core and maybe CPU PLL.

I think that you need to get your CPU Term closer to 1,40 and your MCH Core above 1,40, start to raise your MCH Core first.

Delta between those shouldn´t be more then 0,15v (MCH Core not higher then ~0,15v from CPU Term), boot problems otherwise.

Are you sure that your GTLs are the most stable ones?

okay. noted.

erm sorry, may i know whats GTLs?

Ghostleader

CPU ref and MCH ref.

I've little knowledge on the CPU ref and the MCH ref actually.

Just happen to read a review of this mobo from hardwarecanucks. They too set the GTLs at this voltage for 515 FSB. yep.

Something weird I have noticed:

I'm running the 7a BIOS, and it seems that LLC is broken. I have significant vdroop (.3 or so), even with LLC enabled.

I'm running 7a too. with LLC enabled, my Vcore will not drop but stay at the Vcore that is set.

when it is disabled it is dropped by 0.03 :l
