Wolfdale overclocking thread..

[erocker]

I'm kind of happy with my chip:

10 minutes Orthos stable:

Stock - 3.7ghz = stock voltage
3.75 - 3.8ghz = 1.25v
4ghz = 1.28v
Big jump
4.1 - 4.2ghz = 1.45v
4.2+ 1.48v

@ 1.48v load temps are hitting 75c with a 105c limit.

Now, I am kind of new to Intel overclocking, so If anyone thinks I'm missing something, let me know. I'm a little dissapointed I cant get to 4.5ghz below 1.5v's, but 4ghz @ 1.28v's with low temps 24/7 on air I surely can't complain. I am a bit of a benchmarking whore, so I sell this thing cheap, and right away when the new quads come.

Specs:
Intel Core 2 Duo E8400
SLAPL C0 Stepping
Batch # Q746A489
Version #: E27439-001 1.225V max Pack Date: 01/09/08

I wonder if wizzard would have the inside track on when that could be?

once over 4 the volts have to go up incrementally.. if thats the right word.. exponentially might be a better one.. he he

man, my temps seam really high. 45c idle and 53c load. that's on a awesome water setup. the same setup that my q6600 idles 26c and 37c load. should i be worried?

 

[trog100]

ignore the low readings completely.. the chip sensors read the higher temps but lock at a given figure and wont go lower.. mine locks at 49 C in core temp.. it wont go lower period..

it only goes up to 57 under full load.. the high figure can be considering to mean something.. the low figure is bullshit.. the chips heat sensors do not work properly... or at least a lot of then dont.. later batches might be better i dont know..

its the high (locked) idle figures that make folks think these chip run hot.. they dont..

none of the temp readings should be taken as absolute figures.. simply a relative guide..

i gotta question about readouts im getting in the cpu z program. It fluctuates the core speed from 2000mb to 3000 mb and the multiplier from 6 on the 2000mb and 9 on the 3000mb one. Is this normal or is something not totally working right?

 

[trog100]

its speed step in action.. u can turn it off in the bios.. at less than xxx percent cpu use the multiplier will drop to 6.. its a power saving thing..

best turn it off while tweaking.. or run something that loads the cpu then look at cpu-z..

sometimes it drops the voltage as well as the multiplier sometimes it dosnt.. depends on chip/mobo combinations..

Finally got my wolfy to 475FSB stable. 4.2ghz! very happy now.

thats a nice speed.. any more is just is clocking the the sake of clocking..

i cant get mine to go high at all. I have a gigabyte x38 ds4 board. 4 gigs 1066 mhz ram,. 2 ati radeon 3870s. I scored 21000 on 3d mark 05 on stock settings. I have looked at all the picks of everyones setup but when i try to up my fsb past like 380 itll shutoff n restart. This is my first real partaking in overclocking so im not tuned into the whole lingo. Anyways the other thing i did notice thru cpu z was that its showing my ram at max bandwith at pc 6400 400 mhz max. Yet what i have installed like i said should be 1066 mhz. The board is suppost to accept up to 1200 mhz. Is that possibly holding it back. One other thing i did notice tho is taht i dont have the most current bios flash, but running on 64 bit windows i coulnt flash the most recent.

You should still be able to do a bios flash.

My E8400.

I tryed doing the bios flash, but it said that it wasnt compatible with the 64 bit edition. The one thing i did notice tho is that in my memory that the fsb:dram is 5:8 not 1:1, how do i change that. I was reading up on this a bit and it did say to have that value at 1:1 but i do not know how to change that value.

 

[trog100]

its in the bios somewhere.. 1 to 1 is the lowest.. which can be a nuisance with low multiplier chips and less than stella memory.. u need to find it and use it..

sometimes things have to be taken off "auto" for the extra settings to show up.. its there have a closer look..

just to explain a bit further.. the base clock (fsb) is 333.. 400 memory on auto would be bumped up by a multiplier to run at 400 not 333..

as u raise the base clock the memory speed goes up.. without the multiplier (1 to 1) the memory would start of at 333.. at a base clock off say 450 the memory would be at 450/900.. with the multiplier still in action it would be way higher.. okay if u have super memory but no good if u dont..

Its corsair 8500c memory supposedly rated at 1066 mhz but like i said i was wondering why it shows max 400 mhz in cpuz. I finally found the 1:1 ratio.

 

[No_Limits]

Well thanks for your help trog and another sight which showed me which setting to use for getting the 1:1 timing. i got it to 3.8 ghz. From stock to 3.8 i got a 2000 score increase in 3d05

 

[trog100]

a lot of this go faster ddr2 memory is old stock they fit heat sinks to and rise the voltage a mile.. the spd on yours is probably set at 400 with the original lower voltage.. make sure your voltage is set manually to make sure..

mine comes with an spd set to 800 cas 5 at 1.8 volts.. its sold as 800 low latency cas 4 at 2.1 volts.. it has to be set manually to get it thow.. it will run at 1000 cas 5 at 2.3 volts..

Man you guys are good overclockers, I only have mine at 3.825 @ 1.34vcore.

I did get it to boot into windows fine @ 4.0, ran superpi and everest stability test, but it crashed tried to run 3dm06 in vista and xp.

 

[erocker]

What are the rest of your voltages set at sir?

 

[Exeodus]

ram is at 2.1, i let the board set the voltages for me so I am not sure what they are. The bios doesn't list the values, only what you can increase them by. I'm not sure what program would list the other voltages besides power supply, vcore and mem.

 

[trog100]

u need to boost some of your other voltages a bit.. the vcore looks vaguely right..

Hi guys, i need help with my e8400 Oveclock...

So i got it to run stable @ 4.2Ghz (467FSB x 9), with memory timings of 5-5-5-15.

My goal is to reach 4.4Ghz, i got it to work but Windows isnt stable at all (random crashes at startup etc), i guess its probably the memory BUT when i try to tighten the memory to 4-4-4-12 my system wont boot... Memory volt is 2.0

Any help appreciated
