Question about Overclocking

[Master Disaster]

OK, so i'm finally in a place where i am happy to OC my system (after loads of problems with varying components)

 

I just spent an hour doing some minor OCing (by my standards anyway, had my 8350 running at 4.9Ghz) but as this is my first real pop at OCing on Haswell i thought i'd stop here and get some advice fom the people who know.

 

So what i have done is established a few of my CPUs wall numbers, for example i know that the CPU requires 1.27v to run at a stable 4.4Ghz and even with my full custom loop thats still running with a max temp of 78c, any less V than that and its BSOD city.

 

Problem is i'm not hapy with those temps, 78c is way high for a custom loop when i'm only really beginning to push out of the normal OC zone.

 

2 questions, how much does flow rate interact with temps, if i increase my pump a bit would the temps drop? and also should i continue t push on beyond 4.4 knowing my temps are already so high? Did i do badly in the silicone lottery?

 

Cheers everyone

I'd say for 4.4ghz at 1.27v those temperatures actually aren't bad... especially considering the bad thermal interface inside haswell chips (a lot of people delid them for that reason). To get lower temps, ramp up the fans, they SHOULD help more than flow rates.

you can increase your pump since flow rate does matter to some extent

and may be some new thermal compound could help

ensure all is at its peak and if then also your temps are high and system doesnt go beyond 4.4ghz stable...may be a bad lottery

and if your temps are below 70c, then you can push it a little further say 4.8 max..

yes, try this suggestion also..
