Re: H2c Cooler!!!!

My mobois A00 0P611C (Chipset nForce 680i SLI SPP Rev. A2), and the QX6850 can OC and stable at 4GHz... If DELL's BIOS can support higher than 4GHz, i'll try for 4.33GHz...

 

I did try 4.3GHz before, no luck, no post...!!!

Re: H2c Cooler!!!!

Did you do that in the bios or in ntune if so tell me how you did this. My PC is a xps 720 and I put in the QX6850 and the H2C cooler  and the 1000w psu I ran the program OCCT and the only stable OC I got was 3.3 Through the bios I haven't messed with ntune yet. This is why I can't understand I cant OC over 3.3 I am at a constant 50.c Thanks for your help!!!

Re: H2c Cooler!!!!

Actrually i received H2C unit before the DELL 1000W PSU. so connected H2C unit with 750W PSU, then OC QX6850 to 4GHz (but only use one XFX GTX 260 XXX edition)

 

i did OC via BIOS, under performance, select 333x12, 4GHz (default is x9), if i remember correctly, the voltage is 1.58V at x12. I tested 3dmark 06 for one hour, no problems.

 

u do via BIOS, set multipier to x12 first, then boot into windows, do some stress tests. If passes, great. 

 

BSOD, then re-enter BIOS, decrease multipier by one each time till it's stable.

 

I just got lucky, my QX6850 is quite a Monster...!

Re: H2c Cooler!!!!

Hello how are you changing the multiplier? The bios will only let me change the core clock? If there is a trick please let me know.. Thanks for responding!!! It is the only thing in green that I can change?

What bios are you on?

In the bios did you set the performance to on?
