post #461 of 2861
I've finally found out why my 950 was running so hot at 4.1ghz lol. I forgot to lower my vcore from my previous attempt to reach 4.5ghz and left it at 1.45v .

Now i've lowered the vcore back down to 1.3v and my 950 is running 10 degrees cooler now

That isn't the first time someone has done that, and I guarantee it won't be the last either. :

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

under these settings i get the following result


http://img152.imageshack.us/i/final4...0mhz68624.jpg/

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!

p.s.

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?!

Well, I would recommend about 50 runs of IBT to be truly stable. Although you are definitely looking good here with what you have so far.

Your temps seem high to me but they depend on the ambient temp in your room.

give it one notch of vcore and try again.

I was working my vcore down today and ended up at 1.29v for 21x200. I went down one notch at a time doing a 3 run test of LinX and then got to a point where LinX stopped after 2 runs, put that one notch back and done.

Ok I'll do that. I hate to have to prime all over again. I guess I'll just try some linx runs. Thanks.
