Mind to let us know what board you tested with P45?

Added on June 7, 2008, 9:34 amThanks for share with us. Hardly see bios setting posted by other people. I am working on mine and posted later.

You tried PCI-E frequency increased from 100 to 110 like most people do. Didn't do any benchmark. I heard overclocking this exceed certain number will makes SB crash. I also saw a lot people recommend overclock PCI-E frequency up to 115 for ATI card. Not sure nVidia card.

Mind to let me know what is the motherboard that you are using?

Personally, I still prefer the standard version since I don't have any compatibility issue with memory at all.

@Acecombat, Why not pair with E8600 or E8400 E0 stepping later? I heard this E0 helps GTL Voltage Reference.

About VDroop, it depends on the Voltage that you set. For my case (Rampage formula), when I set the voltage to 1.5125, I didn't see any vdroop at all. However, when I set voltage to 1.5000, it will has 0.01 to 0.005 vdroop.

Mind to let us know what is VMM you mean?

I am using CPU-Z or Asus Probe II to check the voltage.

I am not familiar with nVidia chipset. However, with Intel chipset you got to use over 1.5 above for orthos stable (this depends on the Batch of the CPU, but mostly it needs 1.5v above). I manage to push until 3.84 using E6750 in Asus P5K Deluxe (P35).

@Reuben, you can check the RAM with Memset86. I have same problem before, when temperature goes too high and RAM will out of order.

The temperature of your CPU is very high. Just wonder what HSF you using?

@Reuben

Mind to list your setting over here and we can check it out for you?

@Reuben,

Mind to do a screen shot capture for Core Temp. I want to see the VID of your CPU.

Based on your message above, I assumed your setting as below. Please correct me if the below setting are wrong.

CPU Settings
CPU Ratio Setting: 9.0
C1E Support: Enabled
CPU TM Function: AUTO
Vandarpool Technology: Enabled
Execute Disable Bit: Enabled
Max CPUID Value Limit: Disabled

Overclocking Settings
FSB Frequency - 333
Ratio - 9

DRAM Timing Control - AUTO
DRAM Static Read Control - DISABLE
Transaction Booster - Disabled
Relax Level/Boost Level - 0

CPU Voltage - 1.385v
CPU Voltage Reference - 0.63x
CPU Voltage Damper - Enabled
CPU PLL Voltage - AUTO
DRAM Voltage - AUTO
FSB Termination Voltage - AUTO
North Bridge Voltage - AUTO
North Bridge Voltage Reference - 0.67x
South Bridge Voltage - AUTO

CPU Spread Spectrum - Disable
PCIE Spread Spectrum - Disable

For your case, you must set the NB Voltage Reference and CPU Voltage Reference as stated above. And then, you should just focus on setting FSB Termination Voltage and CPU Voltage only.

Bare in mind, always check your temperature using Asus Probe II. Don't stress your system too much.

Now, waiting for your reply.

Thanks for the tips and yes I realized I'm wasting my time so I got myself an x38 Asus Maximus Formula so I can run pcie16 x 2:D appreciate yoru help though as it did improve my knowledge.

Btw I managed to get it to 3.2 ghz but at an extremely high voltage at 1.485 WITH the pencil mod. Ahsiah has told me it's most likely the high VID I got with this chip and I am inclined to agree. This combined with the stupid voltage droop on the P5K kinda ensures my doom

[/quote]

well i dont.. agree on that
3.6 maybe..
but not for 3.2 assuming ures a G0

i still think ure fsb voltages are wrong..and gtl also
hence ure forcing ure voltage for vcore to push through..

x38 stay away from abit..

[/quote]

So, based on your suggestion, what GTL and FSB voltage should set? what is the right CPU voltage should set as well for 3.2?

[/quote]
typically for quaddies for 400fsb on asus mobos.. with some exception to the x48's and p45's
is usually

GTL 0.67x for all the cores
FSB .. try 1.2-1.4
PLL around 1.6
NB around 1.4v

get this right with lower multis..

if u know ure vcore stock works at 2.4v
then y not do 400x6..
and then just worry on those voltages above first
get them right
and then comes the easy part.. just keep upping ure multi and vcore.. once in a while u need to run memtest to make sure ure NB can support the current speed of ure rams.. u might need to up in a bit..
rams usually u need to up slightly which i suggest u overvolt ure rams.. first

@cstkl1,

in P35, some old revision (not EPU version) I guess still can set the CPU Voltage Reference as 0.63x for 65nm cpu. for those FSB below 450, you don't need to up PLL. FSB termination voltage is around 1.2 to 1.62. NB need to up little but not a lot. This formula so far serve me well in Asus P5K Deluxe up to 495FSB.

Owh I see.. didn't know it is called TRUE ... mine is Zalman CNPS9700NT, it is better if i upgraded to this one or just keep it... I read in the review the performance is good to

@aLWAYStHEsAME,

Zalman CNPS9700NT is a good cooler.

kekeke...
u need the PLL voltage and gtl to 0.67 for 65nm quaddies..and the NB voltages are higher for quaddies..
not going to waste my time arguing with u..

fsb terminationa at 1.62?? did u know y many ppl screw up their mobos??
cause they dont know whats gtls and fsb termination voltage..

[/quote]

Actually, I managed to use 0.59x for Q6600 G0. So, it is not necessary to use 0.67. During the P5K Deluxe time, I am using 0.63x. So, I am not sure your settings and understanding. I just not arguing with you on this matter.

1.62 still ok provided not orthos 7 days non-stop. 1.64 on wards is very dangerous for 24/7 use.

I agree with you on this matter that peoples might not understand this gtl and fsb termination voltage. Hopes people over here use it with your own risk. Don't push your motherboard over limit.

Here is a lot picture about Asus Rampage Extreme. Chinese forum. For those who don't know chinese, can see picture. Worth the see for very details of photo of Asus Rampage Extreme.

Asus Rampage Extreme

What motherboard and bios version you are using?

For Maximum II Formular user, you guys can apply this resolution to fix the thermal problem. It is in chinese. Hopes can get english version other place soon.

If you overclock your CPU with FSB, you got to overclock your RAM too.

Asus Rampage Formula bios updated 0408

Personal experience
1. Memory stability improved.
2. Overclocking FSB increased.

Refer to the url below.

http://www.keepandshare.com/doc/view.php?id=712947&da=y

Please take note, I have test this only with Rampage Formula motherboard. For those with P5E flashed "Rampage Formula" or Maximus Formula owner, use it at your own risk.

What platform you are working on? AMD or Intel?

If Intel, there are two possibilities.
1. Not enough voltage.
2. FSB Termination Voltage is not correct.

If AMD, any AMD Asus OC owner please help him.

I got the same reading number as well when I was using Asus P5K Deluxe. Never manage to get an answer.
