Can you add my OC Mal?

add a "[" at the beginning and a "]" at the end

I'm not good enough with html to figure out how to get an alternating banner and i'm not sure if the forum sig would accept the code. You could always just put 2 banner links though, one above the other.

Yay, I was just typing that your skills are many and that it will come

you two are becoming a nuisance, start a thread and to be honest I'd stop listening to 'trugenius' and his ideas for overclocking your unit.
I don't even think he knows your chip is C2 stepping and the voltage is slightly higher in the first place.

moving along.

king said this many times (like a little kid :lol: )

my apologies for going off topic
though I thought if it concerned amd OCing it was okay
dropping the multi and raising the fsb is a decent idea to get a better OC on a non-BE so I tried it
now FINALLY setting and forgetting

Hi - got 2 questions,

I have a 1090t running at 3.8GHz (200x19). To do that I've had to bump the vcore to 1.42 volts, and I'm very wary or upping voltage! Is this an okay vcore to have at 3.8Ghz? Under this and LinX won't pass.

My second question is for proof of stability, do you need LinX on it's largest size? out of my 8GB ram I normally have LinX using 6.1. If I screenie this running after 2 hours will it count?

Many thanks.

which board, psu, cooler, gpu you are using

2
what about prime95

 

[bardacuda]

1) Depends on your temperatures. 1.42V is fine as long as you're not going much higher than 50°C. Basically you want to keep it below 1.5V AND 55°C

2)If you are using LinX, you have to set it to "All", which will be 5MB less than what you currently have free, but won't necessarily be close to all of your RAM. For me it ends up using about 3 of my 4GB because I'm already using about a gig after booting up. But like genius says you can just use Prime95 instead. Prime95 will not require as high of a VCore to pass.

Board: MSI 870a-g54
PSU: Corsair TX850M

Also I'd like to use Linc as I can get the GFlop score in too I'll put it on all ram when I get back today, but it'll only use another 500mb, hopefully I won't have to up the vcore even more.

 

[truegenius]

@rrruby
your board is limiting factor (due to 4+1 phase power design)
you will need around 1.48-1.5v to stable it at 4ghz
other parts are solid (except hd too)

 

[rrruby]

Ok thanks, I shall keep playing around then, and also investigate this 4+1 phase design, never pUre much attention to that.

Currently at 1.44 volts and temps are good at 3.8. Hopefully i'll have a stable of soon 😀

If you need anything else let me know!

 

[truegenius]

try 1t instead of 2t
it will provide some performance and is a little more stable in case of amd cpu
also try to overclock nb to as high as possible

 

[rrruby]

I'll try the ram timings. Regarding the nb, should I be oc'ing it when I don't have a decent passive/active cooler on it? And is oc'ing the nb achieved by raising the nb multiplier?

 

[bardacuda]

my apologies for not updating database yet.
I'm finishing up a Cray for a client..

http://www.cray.com/Products/CX/Systems/CX1-iWS.aspx

I just can't get away from my old days at Dell..

No problem there's no rush.

 

[rrruby]

After a few tests seems the 1T timing is stable and a fair bit quicker.. first run and it instantly beat my previous best Gflop.

 

[king smp]

bought a 965 BE for $90 USD at local Microcenter
stable at 4.0ghz with just multi raised and everything else on auto
need to play with voltage since it is on auto running at max of 1.52v
think I can manually set it and get lower voltage
finally got my ram running at 1600mhz 9=9=9=27 1T
when I am bored I will also try to tightent timings

nice oc on that 1090T Rrruby

 

[truegenius]

use nb multiplier, fsb or both to raise, max cpu-nb voltage 1.35v and try to hit 3ghz (mine can hit 3.2 but to make it stable @ 1.35v i need to down it to 2.9)
and increase ht to 2.4 to max of 2.6

it incresed my multicore performance very little

@ king
my 1090t is still faster than that 😛
mine 1090t is running at 3.84@1.4v at all core turbo upto 4.08 cnq active (lollipop 😗 )

1.52v is toooooo much, is it c2 or c3

1090's are Thuban though, not really fair to compare Thub's and Denebs
but yes, should be on lower V's for 4GHz there

[truegenius]

he is limited by 4 phase cpu power design and so i am 😛
my 1090t also demands 1.48v@4ghz 🙁 but turbo is providing me some room

 

[rrruby]

Been reading about the 4 power phase design - not going to lie it's worrying me! Apparently this stresses the mosfets, and in MSI boards they can burst into flames. Is it worth looking at buying some heat spreaders to stick on? Already had to RMA my board once! Not sure I can OC my processor much more, even if it is just with turbo core 😀
Does OC'ing the nb make a noticeable difference to performance?

 

[truegenius]

too bad the 'turbo' feature on Thuban's DO NOT WORK..
or at least not like it should.

it works in my case (but sometime it doesn't 😗 )

currently i am using 240x16@1.408v as base and x17 as turbo
when turbo kicks in then my vcore hits 1.488 and on idle it hits 1.216 and x4 multiplier

didn't tested it for stability (stock heatsink :koala: ), but is stable in blend test.

To test turbo, i use winrar bench, peazip bench, constant refresh, and affinity change techniq

My mobo is the Asus M4A77TD Truegenius
you really need to double check your facts before making statements

because actually the Asus M4 series is 8+1 Phase Power Design
