***The Official Wolfdale 8200/8400/8500 Overclocking Thread ***

[kitfit1]

Jokester is right Hesky82. Speedstep, in cunjunction with Eist and Vdroop control, is a perfectly good and safe way of clocking. Even at very high clocks. I don't think anyone would call this a "mild clock" . If you look at my bios settings you will find that ALL the bits that peeps say to disable, are in fact enabled and don't affect my clock at all. Just as a matter of record, DFI do not say to dissable anything when clocking. In fact, Praz, Rgone and Loggan26 and myself, all say to leave speedstep enabled. The only time DFI says to dissable it, is when benching (for obvious reasons).

 

[kitfit1]

why would anyone run at such an uber speed then want to use power saving?

thats like fitting your ferrari with a biofuel switch!

pointless, burn the leccy and enjoy the snappy system.

The system is just as "snappy" with speedstep on. Ram speed is still the same, the only difference is cpu speed. As soon as you want to do anything cpu inensive it kicks back to full speed. Using Word, e-mail, browsing the net, ect ect, does not need a Ferrari. HL2, COD4 and Crysis does, and it gets it

 

[Reality|Bites]

So has the E8500 been found to be a better overclocker compared to the E8400 or are they both the same?

 

[Hesky82]

both the same if your board is happy running 500+ fsb

Just trying to OC my E8400 to 4 ghz. Using an Asus P5E MB with 4 x 1GB crucial ballistic. Coolin wise im on air with a thermalright IFX-14 setup.

Setting ive got so far are
Vcore 1.38v
bus @ 450.Steppin of 9
Dram 2.14v (ive read this board over vols a lil bit) Timings 5-5-5-15 2T
Everything else on auto at the min.

Best i can get with auth is 3 hrs on small FFT's Get to about 60deg C max under load.

Was wondering if anyone has a similar setup and if so what setting they are using. Or what i might change to make it more stable. Bit ne to OC, last time was with the old celron 300's, so a while ago now.

Thanks

You need a bit more vcore to get the stability running small fft's.

 

[Talrinys]

Leave speedstep on, as soon as there's any activity over a couple percent cpu usage it will jump right up to the usual speed, and the power bill without it is stupid to waste money on.

Hi, the board does'nt overvolt the ram. People were reading it at the wrong point. What bios are you on? You need 502 and above for wolfdales. 605 is the latest and is very good. As you are running 4x sticks of ram you may need to increase the NB voltage a notch to aid stability. I am surprised you are up to 1.38v already for just 4Ghz. Most do it with a lot less volts. I would'nt give it to much more or you may run into problems as the wolfdales do not like a lot of voltage. Disable cpu and pci-e spread spectrums and Enable voltage dampner, you may have to increase the NB voltage and maybe cpu pll voltage but no more than 1.6v (minimum is 1.5v on this board). Some have reported better stability with wolfdales by setting the NB reference voltage to 0.63x.

 

[Helfire]

Running this at the min, but will make your suggested changes. Bios is 605. Setting vcore at 1.4v in bios. CPU-z reads 1.336 under load, small fft's, is this that vdrop.? Where is the voltage dampener setting..? Dont think the temp is right says 65 Deg C but if you touch the hrat pipes or block its quite cool.

Thinking of getting an E8200 with 4GB 6400OCZ on a DS3 board.

Will this be OK for some mild clocking?

Thanks

 

[Hesky82]

I would say 3.6GHz is a given with that setup

The Vdroop is terrible on this board but there is a pencil mod that works. I have done it and when i set 1.4v now it shows 1.388 in cpu-z so it's a vast improvement. See how to do it at post #34here.

Sorry, loadline calibration to enabled. It is supposed to get rid of the vdroop problem or at least improve it.

As far as i know, the only thing that reads the wolfdales correctly is Realtemp. There's a thread on it in the cpu forum.

 

[Helfire]

Thanks just done the pencil mod seem to now be geting around 0.05 ish v drop under load acording to cpuz. Dropped things back down to fsb 400 and vcore 1.24, vram 2.2. Build it back up again with those changes you suggested. Doing 10 min oth tests to get a feel of how its doing each time. So each time i change fsb up by say 5 i then change DRam freq to as close to 1066 again and rerun.?

Yes. To start off with keep the Dram Frequency as close as possible to 1066. We can always tweak it later when you find your max. Rather than running Orthos for 10 mins have you tried OCCT (overclock checking tool)? V2.0 is out now and it really is good at testing your overclocks before going for an Orthos/Prime run when you find your max. There's a thread on it in the overclocking forum.

 

[Helfire]

Yeh just got that prog and will give it a try, been running loads of tests and a few more questions, with the ramsettings again.
Some if i set freq to auto it comes up with this.

But if i sellect closest to 1066 Some times a lil bit higher i get



Curently this is what im up to sort of hit a wall at fsb 450,



Here is my bios settings





Any suggestions on where to go from here.? or ways to lower v core. Would be happy with a solid clock of 445. Going to do a long run at 445 setting i had working see how stable it is, but left the modded Pll and nm ref setting at 1.6 amd 0.63, vcore back to 1.412 and see how it goes.

Update passed 30 mins on OCCT 2
Back to Orthos
Cpuz saying 1.352 vcore. So a 0.006 vdrop under load. See how long this goes for.

Thanks

To get my E8500 stable at 4.2-4.5Ghz i had to use the following motherboard settings:-

Vcore 1.45v (not recommended)
CPU PLL 1.7v (not recommended)
FSB termination voltage 1.50v
NB Voltage 1.41-1.51v
SB voltage 1.150v
CPU GTL Reference 0.63x
NB GTL reference 0.63x
SB 1.5v 1.60v.

If you have good airflow in your case then motherboard temps should be ok. Don't give the cpu too much voltage though. Have a play with the motherboard voltages to try to get stable. At 450 fsb i expect it is the NB and FSB termination voltages that may need increasing.

 

[pompeyboy]

my E8200 @4ghz, how long should i test with orphos using the blend test cpu and ram? just stopped it at test 7 so i could browse etc,but am planning on leaving for an hour ?

 

[Foehammer2003]

eight hours as a guidline... some say 24, but 8 hours for me is a maximum i could ever sit at my PC for in one day, any more i get piles [not actually true]

 

[Vipernet]

Up your northbridge voltage and you should see an increase in fsb. My 8200 is rock solid at 4gig 500fsb with the nb at 1.4v with every other voltage up at notch, cpu voltage bang on 1.4v I test stability for approx 8 hours with orthos on cpu only.
