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

Try the RAM at 2.2 if it was stable at that. Only up it to 2.3 if its crashing the PC regardless.

If the extra voltage settings above increase stability then the RAM is obviously fine as no speeds or latencies will have been changed, just a little extra voltage through the CPU.

If its still the same with the CPU voltage increase (above) and crashes out, then slacken off the RAM timings (above) and increase to the other voltages I've listed above! :)

*EDIT*

Just read this back to myself and I'm struggling to understand my own waffle so:

Put simply....up CPU voltage to the setting I listed above.

If its still unstable try the RAM settings (above) at your original CPU voltage... touch NOTHING else)

If its still on the blink..use the settings listed above together.

"Phew"...now I understand! LOL :)

OK here is an update....:eek:

I tried increasing the Vcore but no change. Changed RAM timings to 5-5-5-18 but no go. I have been having a play about today and got it stable @ 3.6Ghz with the following settings:

VCore 1.4875v
HTT 1.6v
NB 1.5v
SB 1.5v
CPU VTT 1.45v
PCI 101Mhz
Mem timings - 5 - 5 - 5 - 15
RAM Auto volts (Was having an issue with not getting past POST and after increasing 1 volt at a time from 1.8v - 2.3v I tried auto and it booted!!
FSB Divider linked, RAM in synced mode
CPU temp around 34 degrees idle
FSB 1600 @ 3600Mhz (x9 mp)

Tried a blend test for 5 hours and both cores held up......

Now heres the weird one......I have tried to increase to 3.7Ghz with the same settings, it gets past post but XP freezes on bootup (Blue progress bar just stops). I have increased CPU upto 1.525v but no joy. Tried changing RAM timings to 5-5-5-18 but still no joy...also tried the CPU increase and RAM timings change together but still the same....freezes on bootup.

Anyone got any ideas on this one? Or am I just being greedy now? :D:D
 
Just to make sure my OC was as stable as it should be I ran an Orthos Blend test for 12 hours last night....No issues whatsoever :D:D

So I now know that i'm working from a very stable setup.....still trying to get to 3.7 without success though!!

Orthos_Blend-3600Mhz.JPG
 
So the saga continues.....

I have been able to increase to 3650Mhz which is looking stable (Only used a blend test for a few hours...will do the usual 12 hours overnight).

The settings I am using are:

VCore 1.4875v
HT 1.6v
NB 1.5v
SB 1.5v
CPU VTT 1.45v
RAM 1.9v
PCI-E 101Mhz
RAM Timings 5-5-5-15 (It will boot up using 4-4-4-12 but does not feel as stable, not run any long tests though)
FSB 1624 (9x mp)

CPUz-3650Mhz.JPG


So all seems OK....but as soon as I try to increase it to FSB 1645 (3700Mhz) with the same settings it gets past POST, Loads XP, allows me to login....but then freezes after 10-15 seconds :confused:

I have tried the following (Resetting to working settings each time unless specified):

1) Same working settings, changed RAM timings to 5-5-5-18 - No boot
2) Same working settings, increased RAM to 1.95v - Loads, freezes after 10-15s (Same as without RAM volt increase)
3) Same working settings, increased VCore to 1.5v - Freezes while loading XP (No login screen)
4) Same working settings, increased VCore to 1.5v, Increased RAM to 2v - Freeze while typing password to login to XP

So tried a few different things....I have noticed that if I use working settings but increase RAM voltage to over 2.1v it does not go past POST...weird as the RAM is certified to 2.2v. It will even freeze the BIOS upon reboot :confused:

OK so there's a rundown so far.....has anyone got any opinions/help on what I can do next? :D

Do you think it could be a RAM issue? If so would it be worth buying a GeiL 2GB kit which is on offer here at OC?

Just to let you know....my temps are all well within normal. CPU 34 @ idle & 45 under 100% load.

Any input/help would be appreciated :rolleyes:

As measured by? If using older versions of coretemp etc.. u're seeing 15C less than it really is (G0 stepping has 100C Tjunction as opposed to 85C for the older stepping). If going by the mobo utility it's likely wrong. Not sure about the latest speedfan and TAT but the core temps will likely need adjusting +15C since you have a G0 chip. Temps you got there seem a little on the low side for that speed and voltage.

My temps & voltages......

Would all these be using the same incorrect temp? Adding 15 degrees is still ok for what I'm doing isn't it? :eek::eek:

3.825GHZ with Volts at Auto 1.525v (with or without vdroop dont matter) or 3.9GHZ @ 1.55v for my max stable of this quiet Noctua NH-U12F+ faster fan.

Also ran a lower Multi and 1900FSB (475x4) with Memory Linked/Sync'd at 950mhz, but CPU and Memory wont go higher even unlinked as seems a large FSB Hole in this bios at that range (1303 by far best Ive ran).
Click to expand...

Thanks for the info....would it be better for me to use BIOS 1303 rather than 1305? Also, would you recommend me using the lower multi?

**EDIT**
What RAM voltage were you running?

I have tried using 8x multiplyer with 1900 FSB but no POST. increased VCore but did not help.....plus...I might be missing something...after setting it to 8x475 and trying to boot....when it failed I went into the BIOS and it was stating 2.66Ghz? Am I missing something here? Definately inputted 8 x multiplyer and 1900FSB.....

1305 is a total POS if you read the forums all over web you will hear that story, some even nuked their eprom with it, I had issues botting up after flashing to it (not sure why, never had issues ever on any mobo).

I could not even boot out of bios with a 1700FSB with any amount of volts on 1305.

Memory should run 1000mhz with 4:4:4:12/2T @2.1v (did on my AM2 Rig) but wont go by that hole with any voltage same as CPU wont so can only assume hole in bios and hope for fix next build.

Above 1800FSB you will need up the NB and SB voltages and may need mess with the other 2 and make sure you lock the PCI-E and HT Buses.

Kill all the settings in bios to do with speedstep and Spectrum crap.

Thanks for the advice....do you know where I can download the 1303 bios? Tried looking on Asus but only 1301 then 1305...tried googling but still no joy :mad::mad:

**EDIT** Found 1303...will be getting that flashed asap!!

Wow what a day! Trying everything in the book now!

I am now using BIOS 1303, which seems a little better....I hoped that it would make a world of difference but no such luck! But has helped me go that little step further so I am grateful to 'helmutcheese' for that call.

I am now stable @ 3700Mhz (I have done just over 4 hours of a blend test using Orthos but will run it overnight just to make sure :D)

Going up to 3.7 hasn't really increased my temps either so hoping that won't be an issue.

My settings are:

VCore 1.493v
HT 1.65v
NB 1.5v
SB 1.55v
CPU VTT 1.45v
RAM 1.95v
PCI-E 101Mhz
RAM Timings 5-5-5-15
FSB 1645 (9x mp)

Will be trying 3.825Ghz (1700FSB) tomorrow.....

Again, thanks to everyone so far for all the help...any more help wouldn't go a miss though ;) :rolleyes::rolleyes:
 
Not such a good day today! Firstly...went with my other half to look for a car for her...all bloody day around Southampton....did we come back with one...did we bloody 'ell!

Then on top of this, came back thinking "oh I will just up that VCore and get 3.7 stable".......no such luck...did not get into an hour of a blend test....so I thought it might be an FSB hole as stated before so went straight for the 425x9 (3825Ghz)....after a bit of fiddling with the voltages got it to bootup but after 10 minutes in XP it BSOD :eek:

I tried upping the VCore to 1.525 but as soon as I upped it to that I went past POST no probs but XP did not load and I got either a DOS error saying system file corrupt or NTFS.sys BSOD error but as soon as I reduced FSB and VCore all was OK...Bloody Windows!

One thing I have found with this Striker board is it seems to not like to much tweaking of either the VCore or RAM voltages....is that just me or has anyone else found this?

I am just about out of ideas and may well admin that 3650Mhz is my last Very stable Core speed and run @ 3.6 daily.....obviously happy seeing as I was having issues getting 3150Mhz only a week ago but still....thought I was on a roll :D:mad:

Just in case any one has any ideas...my settings which got me into XP for 10 minutes @ 3825Mhz were:

VCore 1.5v
HT 1.6v
NB 1.5v
SB 1.6v
CPU VTT 1.45v
RAM 2.05v
PCI-E 101Mhz
RAM Timings 5-5-5-15
FSB 1700 (9x mp 425)

Andy thats 2 of you have said something along those lines.

His CPU is a E6850 and runs 3.0GHZ stock, he aint overclocked it a addition 1.2GHZ.

You are both thinking about E6600's
Click to expand...

Spot on :D

Would be nice getting a 1.2Ghz increase on a E6850 :cool:

Still trying!!

Thanks for the shoulder slap though Andy....always good to hear I can talk the talk even though i'm clueless most of the time! :D:rolleyes:

Well done on the OC though...over 1.6 increase....badaboom!!!! :eek:

Lol.....keep at it mate!!!!

Watercooling Next!!:D

Funny you say that....been reading up on it :D:D

Been thinking if it were best to buy a kit for my first try...might go for one of those kits without water blocks included and buy them separately...:rolleyes:
