Also consider bumping up the LDT and Chipset voltage a notch.

*Set multiplier to 8x

*Set HTT to 300

*LDT Multi at 3x

*Set memory divider to 133mhz

*Vcore 1.55v

*Vdimm at 3.0v

*Chipset voltage 1.7v

LDT voltage at 1.3v

Then see if it boots at that... if it does try 310. The lower multi will take the cpu speed out of the equation and make sure you know whether it is a CPU problem or not.

Im using Gskill LA, yes the HT multi is at x3 (have tried x2 also).

Any help on this would be really appriciated.

thanks

:edit:

I tried the LDT @ 1.3 and no luck, havent tried chipset though

Guess i'll give that a go. Do these need to be raised for high clocks? (Ive never raised them before)

:EDIT:
Bumped both LDT and the Chipset but no luck

Think im going to have to try another BIOS. Any Reccomendations?

Nice one Jokester

Im having problems getting over 300 HTT on my Ultra-d. Im unsure what the problem is - ive gone from stock voltage right through 1.6, ive changed dividers, ram timmings and anything above 300 wont boot (wont go to the windows loading screen)

Can anyone help? Aiming for 2.8ghz [[at 2.7 with 1.4v now]] with my opteron 144 (cab2e)

Thanks

similar probs as me, got my cab2e stabe @ 9x305 1.54V but 9x310 was a no go, even at 1.7V

Richdog · 3 Nov 2005 at 22:00

Gangster did you try my settings?

theboyrob · 3 Nov 2005 at 22:39

Right.... Just done a bit of modding. Currently running at 2.49Ghz, 275HTT x 9 on my opteron 144 CABNE. Can't get over 275HTT with this official bios for the ASRock Dual SATA board, so flashing one of the beta ones tomorrow and will carry on. Running on stock volts at the moment

Jimbo Mahoney · 3 Nov 2005 at 22:40

OK, managed to get my CAB2E up to 2.98 Ghz with 1.60v by dropping the Memory multi down to 120 (15x divider = 198.6 MHz).

I'm finding large FFTs (SP2004) fail my system faster than small, leading me to think it's the memory controller holding me back.

Well, have I got the hump! 146 CABYE 0540 FPBW here, in an Abit AV8 3rd-eye. Can't seem to get 2600mhz (had it also at 2700mhz) stable. It boots into windows and most things work however soon as I click the start bar it locks up. Every time! Also, I noticed that when I first installed it it ran around 38oC idle, but now it seems to be a good 10oC hotter, with no change in speed. It was at 66oC under full load just now :eek:

! I'm thinking this Abit just isn't cut out for overclocking. May have to go with a DFI Lanparty, would that seem a better bet? Ideally don't want to go PCI-Express, so is the Nforce 3 ok?
Cheers

Has the Abit AV8 3rd eye got a PCI-lock...?

that seems VERY high for memory voltage ??

Also chipset voltage safe at 1.7v ?

Seriously, 3v is fine.

Yep, far as I know. There's an option in the uGuru overclocking bit which says "AGP Ratio (CPU:AGP

CI). There's option like 6:2:1, etc, but also one which say "Fixed 66mhz" which according to the manual locks it at 66mhz agp and 33mhz pci. Whether it's working properly is another matter!

Any results on your CAB2E Minstadave?

Minstadave · 3 Nov 2005 at 23:22

Straight in at 2.7Ghz stock volts, not rebooted yet been working, will have more tomorrow if I get some free time

Not for 'standard' memory it isn't ,for example I wouldn't want to push DDR400 Crucial over 2.8v.

matt1 · 3 Nov 2005 at 23:25

Cool man, I've got one sitting on my desk atm. Got back from a 12 hour day doing coursework, shattered. In at midday tomorrow so I might put her in.

Last four number on my 144 CAB2E = 0467

Very nice, can he get anymore is what we really want to know, 3Ghz seems wasy with the 0540s but not seen anyone stable at 3.1, even with the voltage ramped up.

Alas no more expected for the time being and with all but one already spoken for.
Pretty pleased that all ended up 3.0GHz Super Pi 32mb and OCCT stable, none requiring over 1.5675v (in BIOS) to get there.
Likewise none seemed too happy at 3.1GHz, certainly not at 'sensible' vcores.

Actually it is fine. All memory is safe to 3.2-3.3v... whether it is stable or not is another matter. It's only really 3.4v+ that you can run the risks of damaging memory.

Oakesy2001uk · 3 Nov 2005 at 23:49

ok I am Super pi stable a 2.5, I would give u a screenshot but I dont know how to stick it in a post!(yes i'm noob) although 2.5 stable is great, with you guys getting 3.0 cant help thinkin how to get more do I need more volts(currently 1.5). Also if I put the memory on 1T it wont boot into windows?????
Thanks guys!
