E6750 & Gigabyte P35C-DS3R Overclocking Thread

[roorooroo]

Hi again jcossin..is the whine only noticeable when using headphones or would i hear it via my 5.1 speakers?

Vdrop and Vdroop are not the same.


Vdrop is the difference between the idle voltage and the bios specified voltage. That is, Actual versus Specified.

Vdroop is the difference between the idle voltage and the load voltage. That is, the voltage droop under load.

e6850 seems to be a much better overclocking chip than e6750 especially with higher multi, so you should be able to oc it at a lower vcore than most e6750. I would try 1.35Vcore after vdroop to run at spec which i've seen alot of e6850 do at 3.6ghz ... but i guess it all depends on the chip.

Sorry I am not familiar with that term, what does Vdrop means in this case ?

Hello mate, if you open CPU-Z and look at your Vcore while you pc is idle, then open orthos and watch to see if your Vcore Drops, if it does then thats Vdroop, mine does it i can be at 1.344v idle then open orthos and my vcore drops to 1.295.

its annoying, but hopfully Gigabyte will release somthing in a bios update to stop it happening.
And after reading the above post mines also suffers from Vdrop aswell.....GREAT!



Oh and bios F4 is no longer beta its on Gigabytes site.

jeez, the only thing they changed is the ps2 keyboard compatibility. I wonder how we can find out if there were other fixes. That seems like a tiny one. I am using a ps2 keyboard now and I never had any issues.

Thanks, I'll go to bed less ignorant.......

 

[mrfatboy]

I just did some Northbridge temperature testing. I used a digital thermometer with a sensor that had a 6ft cord. I put the sensor right in between the fins of the heatsync.

Orthos stressed with my overclock got up to 47C. Not bad if it's accurate. Then antec 900 cases are great.


Here's my droop info if anybody cares

Vdrop = .042
Vdroop = .074

The whining noise on the built in sound is very noticeable with speakers. The X-Fi sounds fine with my 5.1 Klipsch speakers but when I put on headphones then I faintly hear the whine.

Bottom line, don't use the onboard sound, it is crappy.

K i pulled out my 2nd 2gb ram stick and tried to get it to post with 4-4-4-12 1:1 400mhz with the memory voltage at 2.2v. It wouldn't post, I even tried upping the FSB voltage and the (G)MCH each to +.3v but no dice on getting it to post. Anyone have any tips on why this wont work??

Ignore me ive just gone back and read from page 1.

It would be helpful if you put your Rig in your signature. I have to keep going back to your earlier post to see what you have

Do you have 4 x 1 gig memory or 2 x 2gig? If it is the later, that might be the problem. I heard patriot ram is good but it might not be good enough.

Somebody correct me please, but don't you need at least 2 sticks of ram for DDR2 to work?

 

[wscreamer]

I've got two sticks of 2gb ram gonna fix sig now. but I cant seem to get it to what patriots website says it should run in either setup.

 

[mrfatboy]

Run CPU-Z. Click on the memory tab. Do this with just one 2gig stick in. What does the "type" & "channels" say?

Also, what do the timings say?

Just what I thought. You are not running in dual channel mode with just one 2gig. But I realize that it doesn't work with both sticks in either. Both ways could be part of the problem. I am not a memory expert hopefully somebody will chime in.

Have ever gotten the 4-4-4-12 timings to work even at stock volts and speed? what was the highest speed you OC'd when you lost those timings?

 

[wscreamer]

yah when i had 4gb in i had them running at (9x343) 4-4-4-12 1:1 which of course is very minimal overclocking.

hmmmm.....

I would put the extra 2gig back in. Set memory volts to +.4 (2.2v). Set your FSB volts to normal. Set your mem timings to 4-4-4-12. Now just play with the CPU voltage and see what you can OC to. Make small adjustments. When you hit a wall. Increase (G)mch to +.1v. and see if that helps.

then report back.

 

[wscreamer]

K did that and got the 2 sticks of memory running at 344MHz 1:1 4-4-4-12 but cpu speed is only 3096MHz (9x344). Moving the gMHC up didnt do much if anything. fsb voltage and pci voltage are normal.

Would it make sense to make it not 1:1

 

[mrfatboy]

At this point I'm not sure what to tell you. The E6850 is 3.0 ghz stock and you are barely OC'ing it.

It should have no problems doing 1:1. What is your vcore at 9x343? How high did you try to raise it?

Here is a couple or more things you can try:

1) try the 8x multiplier and see if that helps. Maybe start at 8 x 375 and work your way up.
2) Maybe one of the 2gig sticks is bad. Pull the other one out the try that.

I don't know how good Patriot memory overclocks. Can you return it and get Ballistixs?

 

[jcossin]

wscreamer,

Is this your RAM:

http://www.newegg.com/Product/...x?Item=N82E16820220227

If so your timings should be set to 5-5-5-12 at 2.0V per the specs.

Unfortunately 2GB sticks that are affordable have high latencies.

You'd have better luck getting the RAM I have:

http://www.newegg.com/product/...p?item=N82E16820220144

and getting 4 sticks.

Hope that helps...

 

[jcossin]

Oh, I forgot to mention, I did an interesting benchmark. I ran the World in Conflict demo with my CPU at stock (2.66GHz) and set the ram two ways:

1st way was 800MHz at 4-4-4-12 timings
2nd way was 1000 MHz at 5-5-5-12 timings

Guess what? The 800MHz with the lower timings won! So I can't figure out why people keep buying 1066 RAM that runs at 5-5-5-12 and costs more instead of 800MHz ram at 4-4-4-12 timings!

 

[mrfatboy]

@jcossin
I would have bet the 4-4-4-12 timings would have won. I just read an article about comparing the 800 & 1066. It seems 1066 is not quite worth it yet.

@wsscreamer
oh man! I thought you said you had 4-4-4-12. I should have check myself No wonder it's not working for you. Problem solved!

 

[cleverest]

Hello everyone, perhaps I should have posted my original post in this thread since I'm getting the same cpu/board...if anyone wants to check it out and offer tips quickly before I commit to any of my purchases, I would REALLY appreciate it!

Okay, temps are bit better now. Antec p182b is a case you SHOULD NOT take for overclocking, it's simply too small and cramped. With FSB440 my idle temps went down from 50-51C' to 44-45C' by opening the side wall.

Time to check how that effected burn temps.

Much better, around 10C' drop. From 76-78C' to 66-67C'. (though I also lost the +0.1V FSB, but that shouldn't effect processor temps)

 

[SniperDaws]

Has anyone loaded the NON beta F4?

If so can you try the Auto fan settings please as i think its been fine tuned in this release, in the bios i have both settings set to auto and now when ever i load a demanding app the fans kick in correctly, i made up now because when my cpu needs a bit more fan gas its gets it instead of sacraficing cooling for noise.

Try it and let me know.

 

[SniperDaws]

ok im now running my Q6600 @ 3.2 (8x400) CPU-Z 1.296v at load 1.344v idle (1.4 in Bios) 1:1 4-4-4-12 prime stable for 10 hours till i turned it off this morning.

Temps 63-57-55-63

im leaving it at that for a week or 2.
