The Opteron Skt 939 Overclocking thread !!!!

Darth Sidious · 26 Oct 2005 at 23:39

I would just like to say for all those Opteron owners who actually plan to use their mhz, that I was playing PES5 at 2.7ghz 1280x1024 4AA 16AF /7800gt and fraps reported my fps never dropped below 60

Opterown Power!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

never in human history have cabbages tasted so sweet

Nice clocks CaPtBlaCk.

I feel your pain about the fussy mem controller on these. Couldn't run my memory above 200mhz under phase due to the cold bug. :mad:

aaaahhhhHAHAAHA

awesome dude... just awesome!

i'll be pairing mine with a 7800GTX once my new rig is up and running, whats your clocked at?

i've got a 146 on the way, so hopefully about 2.6GHz or 2.7GHz is what i'm aiming to keep it constantly. obviously more if i can keep it rock solidly stable at higher speeds.

Darth Sidious · 26 Oct 2005 at 23:57

2.745ghz right now im gonna try for 2.8 but i recon it will just fail, i am overvaulting 113% which is the limit with this bios

Shads · 27 Oct 2005 at 00:00

Thanks for all your help today Kesnel m8

don't know how but im at 2749 now just running occt at 1.5 volts

it seems that ever 5htt increase I haft to up the volts 1 now but hay its getting there :cool:

would be good if you can get it stable at 2.8GHz... FX-57 speeds then

No problem mate, was happy to help.

Be sure to keep me updated with your progress on getting it higher.

Yes, so fussy!! I cannot believe that I have LA on the 166/133 dividers! :mad:

I will have another pop at a 1:1 o/c tomorrow but running out of time due to the CABNE. You can also see the awful vcore scaling, I think this core maybe towards the end of the line! LOL!

blknoel · 27 Oct 2005 at 02:09

In sig, currently topping out at 325x9 1.62V, have tried more volts only to get errors in Prime

and thats on air, I cant be bothered going back to water tho ^^

BTW: CABYE 531 IIRC

Sparky · 27 Oct 2005 at 15:00

Thread makes for a good read.You have all convinced me 3800 Venice is about to be sold

.Just got to decide on 144 or 146 now.

Sparky · 27 Oct 2005 at 20:03

Found a UK eTailer with both in stock but which one should i order? 146 for the 10x multi or the 144 and save a few quid.

It depends whether or not you've got a mobo and ram capable of high HTT,if you have then go for the 144 otherwise the higher multi will be necessary to achieve the max overclock possible.

Sparky · 27 Oct 2005 at 20:33

This will run at 280 on the ram so would i be best with the 144?

not at all. you can use a divider. max clocks has nothing to do with multipliers

So Tom,save a few quid and go for the 144?

well you can always run a divider if you're fortunate enough to obtain a chip thats capable of higher HTT than 280(which is more than likely) but tbh I would go for the 146 as it's only a few quid more and that higher multi could prove to be very useful.

Sparky · 27 Oct 2005 at 20:52

I suppose it's going to depend a lot on the cpu stepping i get.If i get a shoddy one,all the htt/multi in the world isn't going to make a difference.

146 it is then.Anyone yet had a decent clocker from 1 of the lesser stepping chips?

Tom

It does if you prefer to run 1:1 with your memory. Although it has been proved of late that tight timings are more preferable for A64 performance than the higher bandwidth of a 1:1 overclock,but yes,of course you are right the multi has nothing to do with how high you can ultimately clock your chip.

Sparky · 27 Oct 2005 at 21:04

Also are these the same as venice etc,where [according to DFI Street] the divider has little negative effect on the overall performance?

I don't run a divider myself as my ram is capable of 275 @ 2.5,3,3,7 timings and unfortunatey my cpu maxes out at around 260HTT so I've never really had use for the dividers but I would imagine as long as you can run tight timings @ddr 400 then running a divider won't have any detrimental impact on real world performance.

I'd still go for the higher multi'd 146 though.
