Post Your Overclock!

[EFH]

Intel E8400 Core 2 Duo @ 3.0 stock clocked to 3.6 with CoolerMaster Hyper TX3

Kingston Hyper X DDR2 1066 @ 5-5-5-12 @ 2.20V

Stable so far...

Max Overclock

I managed to get Win 7 to post and boot at 4Ghz however with 1.55v VCore the overclock was too unstable to survive my choice of P95(x64) and AOD running simultaneously.
It survives this test procedure at 3.8Ghz with no errors after 1hour of stressing.

5870 clocked over 1Ghz after editing the .cfg file for MSI Afterburner (so glad I diodn't have to flash the BIOS on the card)

All clocks now returned back to stock as the x4 940 and 5870 are powerful enough for what I need at stock and I have no need to push them further but it's nice to know how far they can go.

The 5870 still had more to go when I finished testing but the last successful run was 1000/1300

Here my overclock

this is the best i could do, while keeping the system stable.My motherboard will only allow me to raise the vcore 150mv so im limited there.My system temps while idle are 36c it goes up to 51c-55c on full load. I just mounted the v8 with arctic mx-3 thermal compound. hopping the temps will come down a bit after it coures.

Have you done an AMD Overdrive stability test on this overclock as my 9950 was unstable at 3.0Ghz when I had it. It survived 8hrs of Prime95 however errored after 5-10 mins of AOD.

Might be worth looking at if you haven't already.
The 9950 is a very power hungry core with the Phenom I's being a flawed design.
So happy AMD seem to have repaired those flaws in the Phenom II's though.

 

[tremaine]

I just ran the AMD overdrive stability test for an hour, the TMPIN1 temp maxed out at 51C and the 4 cores where at 47c.Ive been running it at these settings for the last week with no BSOD or anything.Did you want me to send you my settings so you can try them on your setup ????

 

[Nokternol]

Thank you very much for the offer Tremaine and if I was still running a 9950 I would do however as I posted just before your original screenie. I am currently running a PhenomII x4 940 setup which I managed to clock up to 4GB however it has not been brought back down to stock as 3.0Ghz is plenty enough for me atm I just like seeing how far my hardware can go.

I take my i7860 to 3.99Ghz but still can't get a 9 second Super Pi. I get a respectable 10 second score.

that's very good Nate......

i wouldn't bother chasing the 9 sec superPI, if you can run it in 10 secs that's bloody quick

Thanks Skunk, for some reason I just think I can do it in 9. I will keep trying.....maybe one day I'll get there. I did another test at 4.09Ghz right after that one:

But still didn't get it. I wonder what it would take my 860 to do 9 seconds....

I am an absolute newbie at this...

I have an AMD 955, 3.2 default clock speed, now @ about 3.75 Ghz

CPUz :

3DMark Vantage ran @ High setting :

Managed to get a bit more out of CPU :

I think I have reached a limit on air cooling.

Nice clocks lads......

 

[Zen00]

Finally hit 4.0ghz, and I'm satisfied. Now to find a stable normal.

all these 4ghz clocks everywhere... , i need to upgrade, lol

nice one Zen....

 

[Zen00]

On the i7's, and even some of the i5's it's fairly easy.

True. The only real worry is winning the 'good chip' lottery.

Even though I have a DO stepping, I still need 1.352 actual to be 24hrP95/20 pass IBT stable etc


Then again, I have other issues going on with this build, so I could just be masking it with a wall of vcore

 

[Zen00]

The next things I guess I should let people know is that I finally got my OC completly stable.

i7-860 @ 3.36Ghz, 3.52 w/Turbo Boost, Clock 160Mhz, Multiplier x21
Gigabyte GA-P55A-UD4P motherboard
Corsair Dominators, CMD4GX3M2A1600C8, 1600Mhz, Multiplier x10, Voltage 1.64, 8-8-8-24

This information is for reference only, and not to be construed as an absolute truth for all setups of this type.

 

[Darryl Licht]

I had it running pretty reliably at 3.6GHz, but backed it down to 3.4 to be safe as this baby is on 24/7 on air.

Just picked up an Athlon II x4 630 on Saturday and got it here so far,

CPU-Z Validator 3.1



Going to give it a few days then see how far it can go.
