[peterg60]

hi all just joined site today hope some 1 can help me get stable at 4ghz with my system all info is listed at bottom what i have done so far cheers

can boot into windows but orthos test will stop after 7 mins

Fill out the system specs under control panel so we can at least know what mobo you have

 

[peterg60]

i have in user cp

 

[peterg60]

ive clicked yes didnt see that sorry

 

[dark2099]

Try enabling Load Line Calibration and see what CPU-Z reads then. That helps against voltage droop (volts actually being supplied being less than what is set in bios) and could increase stability.

 

[peterg60]

in my bios i cant see Load Line Calibration tryed looking for this last week im running bios f8 latest for my board

 

[erocker]

Try setting MCH (North Bridge) to 1.35v for 450mhz fsb. You may need to bump up the CPU voltage too depending on your processor.

 

[peterg60]

yeh it seems my cpu is hungry what is a recommend max for vcore

 

[erocker]

Try for 1.41 ~ 1.42v (shown in CPUZ)

 

[peterg60]

is my mem strap ok or shall i leave all on auto untill i get my cpu stable in orthos

 

[rampage]

many people with the E8X00 line can do 4ghz on stock voltage, but 1.3 should be heaps realy

loosen the ram timings right up and put the ram volts to 2.0v and keep it around the 800mhz mark (or what you know to be stable) and bump up the NB a few notches

but have you tested to see if the NB can do the FSB you are asking ? drop the cpu multi to 6X and then test to see what your max FSB is then when you find that try and increase the cpu multi

 

[peterg60]

but have you tested to see if the NB can do the FSB you are asking ? drop the cpu multi to 6X and then test to see what your max FSB is then when you find that try and increase the cpu multi

could you explain abitmore on this please soyou saying cpu multi x6
then bump up fsb it takes like 650 to 4ghz what vcore shall i leave auto

many people with the E8X00 line can do 4ghz on stock voltage, but 1.3 should be heaps realy

That's only the people with E0's

loosen the ram timings right up and put the ram volts to 2.0v and keep it around the 800mhz mark (or what you know to be stable) and bump up the NB a few notches

but have you tested to see if the NB can do the FSB you are asking ? drop the cpu multi to 6X and then test to see what your max FSB is then when you find that try and increase the cpu multi

After you've found out that your board can do the FSB, try upping the CPU Termination and PLL couple of notches, they helped me to get 4GHz stable. Can't remember the actual settings, but then again I have a C0 E8500 so it takes a bit more juice to hit the same clocks.

could you explain abitmore on this please soyou saying cpu multi x6
then bump up fsb it takes like 650 to 4ghz what vcore shall i leave auto

Go to bios and set the multiplier to 6x. Then set your fsb to 440-450. Test if stable. If so, then keep raising the fsb until it's not stable anymore. That way you can find out the max fsb the board does, without the cpu limiting the fsb that much. (6x450=2700 vs 9x450=4050)

 

[IINexusII]

about the load line calibration, you have it shown as disabled above your cpu voltage. enable that.

 

[peterg60]

i cant see the option in bios is it called something eles it ant in my bios

 

[peterg60]

ok i set 6x 450 screenshots below orthos dont stop straight away everything is on auto even memory and all voltage settings vcore seems high

 

[Inioch]

Can you post a bit bigger pic, can't see anything? Or is it just me?

 

[peterg60]

sorry bout that vcore seems highi still cant find the llc in bios lol

here you go

 

[IINexusII]

voltage is way too high for a 45nm chip. try not to go over 1.35, the e8x00 series dosent need even that much to get 4-4.5ghz

 

[peterg60]

thats what i cant understand the pc wont boot if i give it lower than 1.4 something ant right iand i cant seem whey

 

[peterg60]

my stock vid is 1.3000 and they ant no llc in bios some one said do pencil mod forget that out of my leauge lol

 

[Inioch]

True, way too high cpu. Mine, a crappy C0, did it @ 1.325 bios

Now that you see that the nb can take it, up the multiplier to 9 and start playing with the voltages. Put the cpu @ ~1.3 and start toying with the PLL and termination. Up them by say 0.5 and see if it helps. Also the GTL ref seems to help some people. Also try searching for same kind of setups, I'm sure there are some around the internets.

GL, I have to sleep for a change.

 

[peterg60]

ive done everything i can if i put vcore to 1.3 and play with other voltages pc wont boot if i put vcore to1.3975 pc gets to windows xploading screen then restarts i know chips are differnt but surley not this much

 

[peterg60]

ok i have gone and tryed 3.80ghz instead as 4ghz to much formy head lol ok i have posted a screen what do you guys think does it look ok temps are good orthos on full load only 49c

is vcore ok my board i have found out has no llc in bios and people state it has got alot of vdroop as you can see in screens vcore is a 1.392(bios 1.4365) andfull load it goes to 1.360v

is these vcore safe and is my mem in cpu-z ok cheers

I have been running my E0 at 4.0 for the past several months and have had success at 1.35. However now after reading some of the articles I have about the diminishing return past 3.8ghz, I am trying to down clock to make the cpu a bit happier temp wise. I use d to run at 44C/52C at 4.0...but at 3.8 so far I get 36C/44C, with minimal performance difference and the chip seems alot cooler.
