E6850 on DS3

Black Dragon · 30 Jan 2008 at 18:09

Need a little advice on this if anyone has experience of the combo of GA-965P-DS3 Rev 2.0 and an E6850. Now i know it's not officially supported by any bios including the new F13o (which ive downloaded but not tried yet), currently on the F12. I had the chance to pick one of these up for cheap last week and it arrived on Saturday, so i promptly swapped out the E6300 for it and was pleasantly surprised to see that it worked fine. Even more chuffed when it clocked straight up to 3.5Ghz without a hitch and ran prime stable for 12 hours fine.

Problem is that it won't go any higher. I tried upping voltage to 1.41 and still no go. FSB isn't a problem as i tried dropping the multi to x8 and upping it to 3.5Ghz again and it was fine, i know the board is good for at least 460fsb through the E6300 too. I can't understand why it wont go higher though. Temps are fine, idling 15C - 23C depending on how hot the house is and never goes above 45C even during prime small ftt's.

Could it just be that the board is limiting it as it doesnt really support these chips? Bios, everest, vista, everything ive used show it as E6850 too, except device manager which for some reason seems to think i still have the E6300 in there.

Any help or advice would be appreciated as im finding little to no info of anyone on any site using the DS3 with these chips.

No one have any ideas?

more volts maybe im using 1.425 to get 3.6ghz whats the memory running at?

Memory was on a low divider to take it out of the equation. Seems i was being way too conservative with the voltage. Currently running Orthos for 2 hours so far at 3.7Ghz, upped the voltage to 1.45 but havent tried lower yet.

What's the max voltage for these chips? Might as well stop Orthos and take it as high as i can and then leave it priming over night. Seems this CPU really does have a lot to give after all, i really hadnt expected so much out of it on the DS3 board.

In fact scrub that, orthos failed not long after that post. Ram was only at 820mhz, when it ran at 860mhz day in day out with the e6300 chip. Lowered voltage to 1.425 and priming at 3.6ghz now. Shame, can't for the life of me figure out why it doesn't want to run higher on this board. Looks like i may need to get another to mess around with.

what temps u getting with coretemp?

Black Dragon · 1 Feb 2008 at 13:01

Higher than i'd originally thought, hadn't reaised the old version wasn't reading the correct temps on these cpus. Idle around 38C and 50C load.

krisbutler · 1 Feb 2008 at 13:05

those temps are still fine

krisbutler · 1 Feb 2008 at 13:06

have u relaxed the timings on the ram

krisbutler · 1 Feb 2008 at 13:12

or maybe feed it one more notch on the volts

Black Dragon · 1 Feb 2008 at 14:44

Nope, i've never had to mess with RAM other than upping voltages in the past few years so i've not really looked into that. The ram is running at stock speeds right now, already with +0.1V on it as i thought i'd be taking it higher. It ran higher with the old cpu fine. To be perfectly honest i wouldn't know what to change the ram to to slacken the timings.

Right now it's at 400Mhz 1:1 5-5-5-15

One other thing, is there a reason CPU-Z reads the voltage as only 1.392 when it's set higher in the bios?

krisbutler · 1 Feb 2008 at 15:13

mine is the same in cpuz i think thats idle voltage but i cant be 100% sure nout to worry about though

Black Dragon · 1 Feb 2008 at 20:39

K man, think i'll just stick with what its at instead of fiddling with it more until i decide on another board then.

repton · 1 Feb 2008 at 21:01

my voltages are read lower aswell. 1.625V in the bios.
