PHENOM II AM3/DDR3 Ram Overclocking List

[chew*]

Has anybody tried any Elpida Hyper chip based modules with PHII?

We should team up any buy two CORSAIR Dominator GT 6GB (3 x 2GB) kits and divide them to three 2x2GB kits. 2000/CL8@1.65V sounds pretty good.

Have a set of elpida hypers right here on the desk, not cooperating on gigabyte yet. I think theres an issue with the 1600 divider atm.....trying to get the powers that be to fix it as fast as possible.

Oese whenever I am vague about my settings or voltages there are two reasons.....1 my bench settings are kept somewhat to myself and or 2 they are far from safe and can do considerable damage if proper steps are not taken, this is my way of keeping RMA at a minimum, sadly not all of us are responsible adults........I'm however more than happy to share prime stable settings with anyone etc settings that I consider safe for 24/7 usage.........

If you want to fill in the blanks just type in "UNSAFE" for my voltages.....

Anyone here know if there are any longevity effects to running 2V or so on PII with DDR3? I bought some DDR3-2000 rated at 1.9V for the 955 setup I intend to do this weekend. (I'll be posting results here)

No clue yet,I have stressed them higher however with no deaths....no longevity involved though.

What kind of set?

[Oese]

although i dont think anyone could blame you when trying out your settings and have the ram dieing due to do so, i understand the point.. so i can put in something at least and people know that those are HIGH voltages xD

@ particle: i think up to 2.1v should be safe as i suppose its the same architecture electrically as with those ddr2 controllers, and i ran 2.24v 24/7 on them for some time and higher and never a phenom regardless phenom I or phenom II died on me... I think with ddr3 this issue is quite solved as vdimm decreased a lot anyways..

I think over 2.0v could be the limit i dont get many gains going over 2.0v! I will try and get a faster cas6 done tonight! Am considering buying some corsair Dominator GT from here http://www.overclockers.co.uk/showpr...=8&subcat=1392

Has anyone trys these on a Gigabyte GA-MA790FXT-UD5P!

i know i do not have superpi 32m's attached to these but i will post some previews for now getting my rig reset to run this stuff thursday.

[Oese]

thats very nice for those d9jnl. did you try them before with a lower grade phenom?? i wonder if its the imc that does really play a role here..

if it is the board i must say dfi has to work on it..

could you post your subtimings pls??

[chew*]

Yah definitely run 32m I can run everest with over 1000 errors in memtest.....as well as pi 1M......

[Oese]

i'm sure this is not stable on the other hand my pc does not even boot with 900mht cl7 same voltage... I want to get a clue how good this new dfi is at ram oc... Need 955 phenom in any case...

AOD the HT up, and you can pass everest.....no need to boot.

Sweet Results mate!

i hate aod although i know its a must for super pi and such things...

but cdawall please add 32m's for the list as well

Ehhh, I don't use it to much, most of the time I boot......This way I know i'm stable in cases like 32m stability testing.........but I know ways to make stuff look stable as well......

[Oese]

we will assume noone here is interested in such xD

adjusting htt in windows environment together with voltages etc etc makes testing a lot easier of course.. unfortunately we have to go with bs aod to do so

k10stat is ok for be processors, but for ram... nb of course not possible at all.. so, boot it

same results on a 720BE

Yah definitely run 32m I can run everest with over 1000 errors in memtest.....as well as pi 1M......

ok so it errors out @14minutes...



going to retest @1680 which i know was stable @cas6

[NapalmV5]

whats the highest air cooled 955 clocks @ ud5p/ddr3 ?

[Oese]

same results on a 720BE

you use advanced cooling? looking at your nb clock this comes to my mind...

probably the imc likes advanced cooling and then higher memclocks are possible...

[chew*]

updated still need to play with drive strengths and tweak sub timings for max.....Unsfafe voltage for 24/7

[NapalmV5]

^looks like 955/chipset handles ddr3 quite ok

ive longed for an amd rig.. i may just get amd again

Nice, I coudn't do that on the review bios's, sticks didn't want to play nice at high speeds....just got a new bios, will try again. Might just be the giga don't like the sticks to much. Seems everything on QVL list clocks like crazy and stuff not on list it hates.

Those the v3.1 dominators?

[G.Foyle]

Those the v3.1 dominators?

Yep. They have been seriously abused by the previous owner though, so I wouldn't be surprised if other sets clock even better.

I binned through 3 sets, I need to pray for a change in the bios

[G.Foyle]

I just noticed I have posted wrong screenshot. It's edited for correct one now.
I can boot at 833 CL6, but stability is a no go.
