OC E6850 - 3400Mhz too much to ask on air?

GmanUK · 8 Oct 2007 at 23:35

Hi all.

Just dealing with a few issues at the moment with my new setup. I am running the E6850 on air but for some reason will not overclock past 3370Mhz at x9...running cool but no joy.

Anyone ran the E6850 and had the same issues?

My understanding was I could push 3.6 running on air without much of a problem but not getting anywhere near it....

Thanks in advance for any help.

Are you running your ram at 1:1? Does the ram have enough juice?

Also what voltage, tried bumping up the voltages?

Justintime · 8 Oct 2007 at 23:42

State all your settings, RAM speed, timings, chipset voltages, cpu voltage etc... Your cpu might need a nudge in the voltage section, not all cpus are created equal so even if someone elses 6850 does 3.6 on stock dosen't mean yours will.

Here's my settings:

I'm quite new to the overclocking game, however I have read the OC guide within the forum but still a little unsteady on my feet! :rolleyes:

Any help would be great.

EDIT - forgot my RAM settings:

Re-read the second post on this thread.

AndyOcUK · 9 Oct 2007 at 00:17

Try this:

HTT 1.6 V
NB 1.5 V
SB 1.5 V
CPU VTT 1.45

PCI speed to 101 MHz
The other 3 settings on that menu to 200

CPU VCore 1.45
RAM Voltage 2.3 - 2.4
Disable vanderpool
Set FSB divider to linked and sync mode.

I have the same board with Ballistix RAM and a Q6600:

Sorry....if your point is....answer the question's put to me then I will:

Are you running your ram at 1:1? Does the ram have enough juice?
RAM is 5:6 - RAM set to 2.1v

Also what voltage, tried bumping up the voltages?
Voltages are in images, not tried to bump yet until I have had some feedback from you guys

If you did mean the second post not including my own at the top then:

Voltages/timings are within images posted...a picture speaks a thousand words

I have read, and understand that CPU's are different from one to the other but would like some input from a few people who have walked the same path......

Thank you...much apreciated....will give them a go and get back...again thank you very much.

Did you read the post of mine above mate?

I used to run OcUK Tech so you can trust me, I'm a doctor lol!

Take no notice of the fancy numbers on the monitoring software you are using - they will be way out mate.

Use these instead:

Sorry bud, was answering the post above yours...must have missed it in the cross fire

Thanks a lot for all the info and links....starting on it right now.....

Will soon find out if my sense of smell works when a burning aroma passes by :eek:

Cheers...will keep you posted on my efforts.

AndyOcUK · 9 Oct 2007 at 00:50

No worries mate...the strikers are a bit fussy but once you know what you're doing with them they are solid!

Off to bed now - I'll check up on you tomorrow to see how you're getting on mate - lol

**TOP TIP***

Once you've got it stable at 3.3GHz, save settings as profile 1.

Save arsing about if you need to reset CMOS (or reset the COSMOS as one customer once put it to me on the phone

- I swear I almost wet myself!!)

I knew that computing had a deeper meaning, but to be able to reset the COSMOS, wow!! lol

Thanks for the tips, just about to start making my adjustments. Just one question, when you say save it as 'Profile 1', do you mean using the ASUS AI Booster software or within the BIOS itself? :confused:

cooljimy84 · 9 Oct 2007 at 11:13

In the BIOS so u can load it when ** pc hangs and then resets it's cpu and memory settings

In BIOS mate.

I'm off today so I'll check back every hour to see how u r doing mate!

Yeah, that cosmos reset could have caused havock....planets crashing into each other etc......PMSL

GmanUK · 9 Oct 2007 at 11:51

Thanks guys.

I have made the changes but no bootup, not even POST. I did wonder about this bit:

PCI speed to 101 MHz
The other 3 settings on that menu to 200

I am running SLI so changing my other PCI-E slot to 200 might have caused an issue. I went back, made all the changes but left out the PCI-E clock change and all booted up nicely

I could not find any setting to disable 'Vanderpool', any ideas?

Also, due to syncing the divider it drops my RAM speed to 333, is this so when clocked the RAM has further room so as to not hold back the CPU increase?

Still trying to get my head around it :rolleyes:

melbourne720 · 9 Oct 2007 at 13:13

the trick is, you have to address the part that is failing specifically. If your RAM is underclocked (as it should be when clocking your CPU), your FSB isn't too high, but it still isn't passing orthos then you have to look at the CPU. If it isn't stable then increase the VCore to 1.4. CPU clocks fail because (a) the chip isn't capable or (b) not enough voltage assuming you've elimiated the other components as causes. This means knowing what your boards max FSB is (try at 400 x 6 for example) and making sure that the RAM is less than what it is capable of.

Your right mate, set the second to 101 not 200 if in SLi

Post CPUz screenshot mate - this is where it gets interesting and any further help will be forthcoming much more quickly and easily with screenshot info!

GmanUK · 10 Oct 2007 at 15:44

Wow what a couple of days this has been!

I have been trying to get this thing OC'd but not really having much joy.

I have increased the voltages as per your specs but still seems to want to crash...mostly getting NTFS.sys BSOD errors before going belly up!

I have got my case about 15 degrees cooler which has taken my cpu down from 40 degrees to around 27 with no load so heat is not an issue anymore.

Heres the issues I'm having:

1) I can't find 'Vanderpool' anywhere in my BOIS to disable it.
2) I am now getting issues with loading/saving of profiles...even if I flash it again and make some changes then save as a profile it will not get to POST on reboot....the only way it will reboot after making changes is to not save the changes in to one of the profiles and just do a 'save and exit'.
3) When increasing the FSB within the BIOS, it will boot in to OS but as soon as I run any tests it will fail. I can get it stable at 3150Mhz...when I say stable I mean that the tests will run for a few minutes...not the 8 hours as needed.
4) I'm going off the colour blue!! :eek:

Phew...glad I got all that off my chest

AndyOcUK · 10 Oct 2007 at 21:52

Some more settings to try:

Turn Off ALL references to "Spread Spectrum"

"Vanderpool" is Enhanced C1 option.... (Look in the BIOS right pane on this setting mate...states Vanderpool clearly!

Disable Speedstep

Finally...PLEASE post a CPUz screen shot. It REALLY will help us to help you.

GmanUK · 10 Oct 2007 at 23:06

Thanks a lot for the extra info.

I have disabled all occurrences of "Spread Spectrum". I have also found the 'Vanderpool' option.....yup I am blind!! Disabled Intel Speedstep.

I have increased the Core to 3300Mhz...and touching wood...all seems stable at the moment and only running at 32 degrees idle. I will run a test overnight to make sure all is well

Its a start...thank you very much for your help so far!! :rolleyes:

Here is my up to date CPUz screenshot:

Hope to take it further tomorrow
