hi professionals:)

my gaming rig is:

ASUS P6X58D PREMIUM

INTEL CORE I7-950 with CORSAIR H70 PUSH AND PULL with scythe slipestream x2 1900 rpm

MUSHKIN Silverline Stiletto 998947 3x2gb 1600 mhz 7-10-10-24

ATI 5850


and now: i get my system stable at 4,2 ghz at this setings:


multi 21
bclk 200
qpi 1,35
1600mhz dram frequency
unclk 3200
qpi link data rate auto

cpu voltage 1,35
dram bus 1,65v
cpu pll 1,90v
ich voltage auto
ich pcie voltage auto
ioh voltage auto
ioh pcie voltage auto

LLC enabled
cpu clock skew auto
ioh clock skew auto
cpu spread spectrum disabled
pcie spread spectrum disabled
c1e disabled
hardware prefetcher enabled
adjustable cash line prefetch enabled
intel virtualization tech disabled
cpu tm function disabled
execute disable bit enabled
intel HT technology disabled
active cores all
a20m disabled
intel speedstep tech disabled
intel turbo mode disabled

under these settings i get the following result

under 79 C in linx...

i am satisfied with these settings and clock for 24/7 use but i am wondering if it could go up more?

i tried 200x22 or 21 x 205 or 21x 210, and with every of these combinations, my system isnt stable.. I tried to set vcoe around 1,4-1.45 v.... again no stable..

is it posible that i am runing stable 4,2 ghz with 1,35 v and for only 200 mhz more, i need so high vcore????

is there any advise to change some of these setings from my bios written above?

any advice would be helpfull thanks!
 
do you game ? encode cos i thought anything above 4 gig or over would be a waste... maybe im wrong....
 
No point getting more than 4 ghz. I got mine at 4.4ghz but it wasn't stable, so I downclocked to 4.0 ghz, and have not noticed any difference, except that temps are 10'c cooler.
 
for past 4 hours i have tried different combinations - 21x210, 20x220, 23x192..interesting that i need 1,344 v vcore for stable 4,2 ghz... and for 4,3 ghz or 4,4 ghz i need to push vcore to 1,4 to boot the system but it cant be stable! i run linx on 4,3 ghz or 4,4 ghz, and after 12 seconds, when linx pull out 100 % load, apears BSOD with the same errors 0x0000101 and 0x00009c...

i tried raising vcore to 1,45 and qpi to 1,55 but i cant get stable 4.3 or 4.4 ghz!

batch is 3034A681 if it is important?!
 
yeah, it goes up logarithmically with frequency. i need 1.18 for 3.8, 1.25 for 4 then 1.35 for 4.2... i'd probably need 1.45 for 4.4
 
It really is very difficult to get it stable above 4ghz. I did 21 x 210. I had a voltage of 1.41, and left everything else to Auto. It was very hot and unstable. (I assume your uncore is exactly double your ram frequency?)
 
hello i just followed 3-step overclocking guide...

1. step- my maximum bclk was 220 ( with qpi 1,2v) and 222( with qpi 1,45v)


2. step- my maximum memory frequency was 1760mhz 9-9-9-24 with qpi 1,425v

3.step- i tried multipliers: 20,21 and 23...according to the guide...


my goal was to reach 4,3 or 4,4 ghz( i already have set everything stable for 4.2 ghz!)

for 4,3 ghz or 4,4 ghz i tried every combinations of theese multipliers and bclk:

20x220, 20x215

21x210, 21x205

23x191, 23x187


in theese combinations i tried CPU vcore
from 1,35 to 1,5 v and qpi from 1,4v to 1,5v.... AND.....

I CANT REACH STABLE 4,4GHZ in anyone of theese combinations!!!

I CAN ONLY REACH STABLE 4,3 GHZ IN ONLY ONE COMBINATION 21x205 with CPU vcore 1,425V and qpi 1,425v too...
but with this combination temperatures under load raising above 80 C i decided to use this for 24/7:

4200 MHZ
BCLK 200
MULTI 21
CPU VCORE 1,344
QPI 1,4
DRAM FREQUENCY 1600 MHZ 6-8-6-24
CPU PLL 1,88

in idle my temperatures are about 38, 39 C and under full load in linx, after 1 hour, about 75 C


what do you thing guys about this results?

p.s. obviously my i7-950 is not so god to go above 4,2 ghz...but it is stable at 4,2ghz..
