Help With Stablilty

[SubScriptZero]

Hi all,

A few days ago the pins on my stock intel cooler fell out and refused to hold, So i decided to use the opportunity to upgrade the cpu cooler. I went with a Corsair H80 (Closed loop water cooler).

Anyway, I figured as It will now run cooler I should have a go at overclocking.

So far Ive hit 4GHZ stable. (It seemed stable)

I ran Intel Burn Test, Heres the results;

Very High 5 Passes (4096MB - 8 Threads);
Took < 3 Mins per run
Average 56.8 GFLOPS
Asus Pc Probe top temp = 67 C
Hw Monitor top temp = 69 C

Maximum 1 Pass (22512MB - 8 Threads):
Took 33.2Mins
Average 52 GFLOPS
Asus Pc Probe top temp = 74 C
Hw Monitor Top Temp = 76 C

Overclock settings;

CPU Ratio = 21
BCLK Freq = 190
DRAM Freq = 1523MHZ
CPU Voltage = 1.29375
QPI = 1.3V
DRAM Bus = 1.65V

(Everything else is Auto)

My questions are
1: Is this a safe OC?
2: How much further should I push it?
3: What else can I change to improve the speed?

Turns out its not stable. Had a crash yesterday, dont really know what for as I had simply left it on (Not doing anything intensive). I down clocked it to 3.7GHZ which seems to be completely stable. However, I would really like to hit 4GHZ. Any help would be much apperciated

Is your ram rated for 1600MHz?

You can go a fraction higher on vcore I think, 1.35?
