Worst E6600 ever or do I not know what I'm doing?

[AndrewZorn]

I feel like supernoob3000 all over again.

I can't get my E6600 stable at even 3.3ghz after installing my Ultra 120. CPU is stable at 3ghz at 1.33v on the stock cooler!


CPU Freq: 366
Dram Freq: 732/915/976 (have this memory at 1000mhz stable right now)

Performance: Standard/Turbo
PCIE Freq: 100/102
PCI Freq: 33.33

Memory V: 2.20
CPU V: 1.4125 (i know it could use more but come on 3.3ghz? my vdroop isn't that bad either)
FSB Term V: Auto/1.2
MCH V: Auto/1.5
ICH V: Auto/1.05

Modify Ratio: Disabled
Microcode Updation: Enabled
Max CPUID: Disabled
Enhanced C1: Disabled
CPU Internal Thermal: Disabled
Virtualization: Enabled
Speedstep: Disabled

Configure DRAM by SPD: Disabled/Enabled (when disabled, I use verified settings)
ECC: Disabled
Hyper Path 3: Disabled
DRAM Throttling: Disabled

I cannot use EZ Flash since going to 1503! When I go in, it just never fully loads and lets me take control.
Is there a Windows-based flasher for the P5W?
I'd simply like to try 1407 before I give up here...

Any settings I'm missing?

EDIT UPDATE: I got it flashed to 1506 Official. It was stalling out because Defaults has a floppy drive and I do not, so it was searching for that indefinately.
Still not helping any though.

[DAK1640]

Supply a DETAILED listing of your BIOS settings...

[AndrewZorn]

i updated the first post a bit with the new info but still having trouble, i cant hardly boot at 3.3ghz with above settings

[DAK1640]

You forgot your rig specs, however, try this...
Vcore: 1.425V
Multi: 8X
FSB: 400 @ 1:1 (DDR800)

I'll bet it boots and remains stable.

[^don.k's^]

Try with performance mode auto.
Also try this

Memory V: 2.20
CPU V: 1.5
FSB Term V: 1,3
MCH V: 1.65
ICH V: 1.2

Usually, every 100mhz more needs 0,05-0,1volts more to be stable, default vcore is 1,35v, you want 300mhz more, i'd try at least 1.5-1.55v.

Regards! :toast:

[politenessman]

use asus update to flash in windows. has option for flashing from a file. and it seems like your ich, mch, fsb and vcore need some more volts.

[Shpoon]

With regards to EZFlash, does it hang when you enter? That happened to me, I had to reset CMOS (use the jumper), and then I could access it.

[AndrewZorn]

teh EZ flash i fixed by disabling A:\ which was on by load defaults so it kept looking for that forever
only happens with like half the bioses

3.15ghz not even stable at 1.4 but thats default ICH, MCH, etc

i was under the impression you never needed to raise them unless youre going over 420fsbish?

is 1.3 fsb, 1.2 ich ok, and is 1.65v MCH ok with no additional cooling other than the passive stocker?

i should try 8x to see if its CPU or not cpu

[AndrewZorn]

You forgot your rig specs, however, try this...
Vcore: 1.425V
Multi: 8X
FSB: 400 @ 1:1 (DDR800)

I'll bet it boots and remains stable.
specs in sig
doesnt even boot

now im pretty sure im doing something wrong
though my settings for 3ghz have worked perfectly even since the stock cooler!

by teh way is 1.5v ok for 24/7 air!?

[DAK1640]

You must have overlooked something...
1- What is your E6600 stepping?
2- I can do 435 without changing ICHv & MCHv
3- 1.50V is very high for 7x24
4- Review the P5WDH sticky...lots of good info...I am using BIOS 1503
5- Try a divider on your Ram...
6- What PSU ?
7- Don't go raising volts needlessly...carefully monitor temps...What does coretemp show when you run SP8M during a stable boot?
8- Carefully go thru the BIOS options again and ask about anything your not 100% sure of.

I wish you well & a smiley face when your thru...:banana:

[AndrewZorn]

its a week 29 i think
PSU is tagan 480w
ok to the rest

anyway i tried 400x8 with 1:1 and 5:4 and 1.425 volts... no boot either way. i simply dont get it. do e66 really get this crappy? that it can do 3ghz on 1.35v prime stable all day, but fail 3.15ghz with 1.45v and a way better cooler????

i mean
its 'only' 20% or so faster than the opteron i had
but its only seeing 3.6 all the time that disappoints me

i dont even know what else to TRY other than clearing CMOS through jumper and starting over again.

ive tried like 4 different BIOS and im back on the latest official 1506.

EDIT and at least the ultra 120 is doing me good... 40*C max in speedfan (during double large fft) at 1.35v. so i cnat imagine CPU is getting too hot (at least, to boot)...

[Trice]

Only 20% eh? Thats a pretty significant amount. Dont feel too bad, 3.6 is still good.

[adrift02]

Well I bet u need more then 1.43 to hit 3.3. Its not that rare for that to happen. For instance, I need 1.35v for 3 gigs stable. Yet I need 1.537v for 3.4 stable, 1.45v for 3.2 stable (unless its a 8x multi, then I need 1.475), and only 1.2375v for 2.7 stable. My point is, any previous voltage/oc doesn't indicate what you will need for other speeds. It becomes a slippery slope once you get over 3.0 with conroes. I hope you have at least tried 3.3 at 1.5v before posting, as this is the only way to know if its a cpu limitation. Its not going to kill anything to try it as long as u keep an eye on your temps. Obviously just not for 24/7 use unless ur rich. But I can do orthos at 1.537v on air without my coretemps going over 60c which is fine for testing. Again, as long as ur not dumb enough to run those volts 24/7 its fine to test with em.

[zemzelett]

I agree with adrift02, my E6600 goes to 3.8 at 1.3v to post, but do actually get into windows, it needed 1.55, course theres a little droop as well. My jumps in volts to be stable was something like 1.3v for 3.0, 1.4v for 3.4, 1.55v for 3.8, and beyond that i dont know since by board sucks and wont go anymore. My temps changed quite a bit under phase change, stock loaded its -52C on the vapo window, 2.6 and above its always been -37C loaded. Never have got a real temp. of the cpu yet, bios shows -25C, asus probe is +256C, and core temp is -1C loaded or idle doesnt matter, those are always the temps. so im sure none of them is working correctly.

Mine is a week 27 retail chip by the way, seems like a good one, but i wont know until a better board comes along with SLI support, hoping the 680's will magically come to life, and overclock more then they currently are.

[syne_24]

every chip is different, so dont be afraid to raise the vcore. It's the only way to tell if everything else is set right then it must be what's holding you back. You need to play with some vcore and vmch to see what works for you. Also memory divider on this thing is picky with anything over 1000. Try to keep it 1:1

what is your goal exactly just 3.3 or 3.6?

CPU Freq: 366 *9 (use x9 multi, some boards/chip are picky on x7 or x8 on certain bios)
Performance: Standard
PCIE Freq: 101
PCI Freq: 33.33

Memory V: 2.20-2.3
CPU V: 1.41-1.45v *you might need more depending on cpu
FSB Term V: Auto or 1.4
MCH V: 1.65 *if your running 1000 on the memory put 1.75v for better stability
ICH V: Auto

Configure DRAM by SPD: Disabled/Enabled (when disabled, I use verified settings) *I would try manual with the default rated timing
ECC: Disabled
Hyper Path 3: Disabled
DRAM Throttling: Enabled

disabled anything not use such as firewire 1394/ one of the ethernet port/jmicron if not use/serial port

goal/ideal is 3.6 so i was gonna get to 3.3 first
2.2v gets me 1000mhz 4-4-4 on the memory, im sure of that
though i thought default FSB Term was 1.2v, not 1.4v!!! this could be the entire problem! i will try 1.4v and see if that helps

[thunderstruck!]

If you want to monitor temps, use TAT (http://shintai.ambition.cz/files/tat.exe). Third party software is inaccurate.

Also, overclocking isn't guaranteed.

[AndrewZorn]

yeah i know its all just for kicks of course
i got 3.15ghz stable by LOWERING my timings... perhaps the RAM doesnt like running 4-4-4-15, only 4-3-4-4???

eitehr way i try again tonight with 1.4v FSB. what does increasing FSB termination increase temps/volts on? board cooling, cpu cooling, etc what is desired?

EDIT if more vcore makes more stability, does that mean that the 'problem' lies 100% in the CPU? like what if something ELSE was wrong, that was making me need absurd vcore to get respectable speeds?

1.45v in windows = 3.3ghz stable so far
CPUz keeps blinking between 1.44 and 1.21 i dont konw why
1.475 in BIOS

Yes if more vcore makes it stable then most likely because your cpu needs it. But if you still have stability problem after a rediculous amount of vcore, then it could be something else such as ram timing/divider, maybe more vmch, temps, bios etc.. Also remember asus's board has a pretty bad vdroop; therefore, what you set in the bios will dip to about .05v under heavy load such as orthos. But like I said, every chip is different, some can do less vcore while other needs more. You should be able to do 3.6 tho, all of the e6600's I have messed with can, just different vcore to get there.

[Rol-Co]

sorry to say this m8, but i think you got a very crappy p5w deluxe, my first one didn't even do 400 fsb on 1,65 vmch, and your's looks about the same.

try 1,65vmch and see how it react...or try another board , a p5b for example if you can.
for sure its not the chip, testet about 20 overhere now and all the chips did at least 3400 with no problems.

[dab420]

my p5b deluxe is worse than my P5W DH.. I was folowing this thread for advice lol

[Phoenix_TT]

Details of my sys:

Core 2 Duo E6600 - I think week 24
Asus P5W deluxe 1503 BIOS - 66M0AG/G0EAY, max MCH of 1.65V
1 GB (2X512Mb) of Cosair XMS2 Twin2x1024-6400C4
Scythe Katana Cooler + Artic Silver paste + 92mm silent FAN
Artic Silver paste for NB + SB heatsinks and removed the coverings
Ultra-Quiet ATX PSU 400W, 120mm fan

On all AUTO settings I can get to 3.2GHz!

Try these settings:

CPU Frequency: 400MHz
DRAM Frequency: DDR2 800MHz
Performance Mode: Standard
PCI Express Frequency: AUTO
PCI Clock Synchronization Mode: AUTO
Memory Voltage: 2.1V
CPU Vcore Voltage: 1.55V
FSB Termination: AUTO
MCH Chipset Voltage: AUTO
ICH Chipset Voltage: AUTO
Digital Home Mode: Disabled

Under Advanced Chipset:

DRAM Timings by SPD: Enabled
DRAM ECC Mode: Disabled
Hyper Path 3: Disabled
DRAM Throttling Threshold: Disabled

Under advanced CPU settings:
Modify Ratio Support: Disabled
Microcode Updation: Enabled
Max CPUID Value Limit: Disabled
Execute Disable Function: Disabled
Enhanced C1 Control: Disabled
CPU Internal Thermal Control: Disabled
Virtualization Technology: Enabled
Intel (R) SpeedStep (tm) tech: Disabled

Core Temp 1) 52°c 2) 54°c
Intel TAT 1) 54°c 2) 55°c

I haven't really tested for stability except for just running SiSoft Sandra's Processor Arithmetic and Multi-media tests. I use this as it's quick and through my overclocking attempts sometimes it will fail and hang on the Processor Multi-media test.

With an FSB of 400 and CPU Vcore of AUTO it won't boot and with a CPU Vcore of 1.5V it boots but doesn't load Windows.

3.7Ghz and FSB of 412, I need these settings:

CPU Frequency: 412MHz
DRAM Frequency: DDR2 824MHz
PCI Express Frequency: 110
PCI Clock Synchronization Mode: 33.33MHz
FSB Termination: 1.5V
MCH Chipset Voltage: 1.65V
ICH Chipset Voltage: 1.2V

with CPU Vcore at 1.55V it doesn't boot, with it at 1.6V it boots but doesn't load Windows and at 1.65V it boots and loads Windows.

The temps are
Coretemp 1) 60°c 2) 62°c
TAT 1) 63°c 2) 64°c

It will run Sandra's Processor Arithmetic test, but will hang on the Multi-media test. I'm not prepared to increase the CPU Vcore anymore.

I now have a OCZ GameXStation 700W PSU, fans on SB + NB and Thermalright Ultra 120, so I will try the settings again. I will also try running prime and orthos and see what happens.

It would be nice to run at 3.6Ghz with a lower CPU Vcore or go higher, so any advise appreciated .... maybe memset ?

[AndrewZorn]

i didnt want to go over 1.5 on vcore... or even up TO 1.5... so is that the problem? i thought these 65nm chips wouldnt like over 1.5 for 24/7...

[Phoenix_TT]

Well I think the max according to Intel's datasheets is 1.55V for CPU Vcore. It is well known that the P5W DH has droop of up to 0.5V. However it's your kit, so try at your own risk ;-)

[syne_24]

i didnt want to go over 1.5 on vcore... or even up TO 1.5... so is that the problem? i thought these 65nm chips wouldnt like over 1.5 for 24/7...

With good air cooling I would say 1.55v is fine for running 24/7 but just watch your temps closely. Since your chip doesnt seem like a great overclocker, you need to find out what you can get out of 1.5v then. I would look over all the settings, loosen your timing and try to run 1:1, give it some extra vdimm like 2.3v and vmch 1.65v, boot in windows and use clockgen to find out how high you can get with 1.5v. Once you know what is that max fsb for 1.5v, go back and set it in bios, run some orthos test, lower fsb with clockgen if neccesary, and start fine tuning your vdimm and timing to see if affects stability. BTW i hope you're using either 1407 or 1503, it seems to be the best one so far.

[AndrewZorn]

- my board droops less than .02 so i got a good one in that respect
- ive verified the memory to run at 1000 4-3-4-4, memory controller is not integrated so i didnt think it coudl affect stability like on AMD, only the dividers (1:1 and 5:4 seem to be the only ones that work)
- ill do 1.5v in BIOS max i suppose, thats what i was thinking too.
- 1506, latest official.

[AndrewZorn]

so if i cannot even get 8x400 stable (but can get 9x355), its the board?

wonderful... because i AS5d it...

[MrDeeds]

i didnt want to go over 1.5 on vcore... or even up TO 1.5... so is that the problem? i thought these 65nm chips wouldnt like over 1.5 for 24/7...

This seems to be your problem to me.
You have to be willing to drop some volts into your cpu to at least find out where you see gains. Im not saying run volts your not comfortable with 24/7.

But you have to find out the cpus limits. If you're truly fsb walled at 9x355 then i'd have to say something is wrong with your board but if you havent even seen if your cpu is one of the ones thats scales better with higher volts then you havent explored all angles.

[AndrewZorn]

yeah but on air is 1.6v safe, even for short periods?

[tcG]

yeah but on air is 1.6v safe, even for short periods?

1.6V is fine for short runs.

You need to drop your multi waay down and kick your FSB to around 400FSB, just to see if this is your CPU or actually your motherboard.

Hi Andrew,

I need to apply 1.45Volt for 3.25 Ghz and 1,475Volt for 3.3 Ghz on air.
So just like you, I can only envy those who get 3.6 Ghz and even higher with no effort at all.
I have tried every single setting, but my E6600 is not a Schumacher.

[Clump]

It seems that some E6600s like the volts. I see people running 3.6GHz at under 1.4V, but mine needs 1.5625 to get 3.4 stable. That was about the limit on air and after 24 hours Orthos the temp peaked at 66C in Core Temp. To get Orthos stable at 3.6 (400 FSB x9) needs 1.5825, which peaked at 77C within minutes when I stopped it.

[Lestat]

<-- 3.6ghz 1.28v :)

:rocker:

[MrDeeds]

<-- 3.6ghz 1.28v :)

:rocker:

Not a fair comparison, you've got an es.

[AndrewZorn]

aaaaaaany other ideas before i cry again

[syne_24]

aaaaaaany other ideas before i cry again

try these settings here i posted with vcore 1.6v, mem:800, voltage mem 2.25v, vmch 1.65v

If that doesnt even boot, you either have a really bad overclocker cpu, bad ram or board.

My E6600 is almost identical to yours, mine is a week24, and clocks like this at a selected Vcore in BIOS to be 24/7 stable.
