Waco Posted March 2, 2012 Posted March 2, 2012 Waco that's a nasty score you got! You OC that new 2600K yet? Yeah that's at 4.7 GHz on the CPU (~1.4 volts) and 1000/1200 @ 1.250v on the GPUs. The new 2600 will boot to Windows at 5 GHz with only 1.4 volts but isn't stable for IBT/Prime/etc. I don't want to crank the voltage much higher even though cooling obviously isn't an issue.

NICE oc on the 5970's. How much you pay for those bad boys? Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted March 2, 2012 Posted March 2, 2012 Up to 1.44V's is fine. Never had any issues running 5.0GHz on my i7 2700K at those voltages. I stepped it down to 4.9GHz at 1.416V's to get my RAM timings stable when I switched them around. Have you found your best overclock per voltage, yet? On my brother's i7 2600K, he gets to 4.7GHz at 1.35V's... going higher takes more voltage. Share this post Link to post Share on other sites More sharing options...
El_Capitan Posted March 2, 2012 Posted March 2, 2012 Well, I ran some benchmarks, and some pretty nice comparisons between systems: i7 2700K @ 4.9GHz, two GTX 580 1.5GB's in SLI at 900MHz Core Clock (weak, I know), with a GTX 560 Ti Dedicated PhysX card at 900MHz Core Clock (forgot to overclock it to 990MHz): Performance P12661 Xtreme X4557 Now here's where it gets interesting.

Nyt Posted March 2, 2012 Posted March 2, 2012 but there is the bclk straps Highest BCLK is like 125 and using BCLK straps will degrade your chip ... Theres a reason you are meant to use multipliers Share this post Link to post Share on other sites More sharing options...

Further proving there is no need to upgrade from my 930 yet! I am thinking about getting a Phantek's cooler and pushing my i7 higher than its ever been before. I've gotten it to 4.6GHz before while never going over 1.4 volts, it wasn't exactly stable but it was able to get a 32m run of wPrime with it and snap a screen shot without it BSOD'n. I feel like my 930 is a champ of a chip and could push even higher if i wasn't afraid of melting it. I dont have the time or money to put it under water, but an air cooler than is most likely 8-10c better than my Megahalems really ought to make a big difference. That Phantek's actually competes with lower end custom water cooling! Highest BCLK is like 125 and using BCLK straps will degrade your chip ... Theres a reason you are meant to use multipliers I don't know where you read that the BCLK straps are bad for your chip and will degrade them. Because that's absolutely not the case... The BCLK straps were pushed out my Intel not board partners... And they go from 125 in varying levels all the ways to 250... using the BCLK straps is no different than any other form of overclocking. If you keep temps down and voltage in check, you're golden! Share this post Link to post Share on other sites More sharing options...
Waco Posted March 2, 2012 Posted March 2, 2012 NICE oc on the 5970's. How much you pay for those bad boys? Its just a single 5970. I can only OC it because I put it under water. With the stock cooler it hit unsafe temps if i did anything. Share this post Link to post Share on other sites More sharing options...

Yeah but 125 is usually the max you will get stable. Many LN2'er have had chips benching at 125 BCLK for high OC's and the next run they cant even get 5GHz anymore to run. But go ahead and use BCLK straps, not my problem if you kill your chip Share this post Link to post Share on other sites More sharing options...

You might as well claim that changing the multiplier damages chips. Share this post Link to post Share on other sites More sharing options...

Yeah, the only thing you'll improve is the physics in games, otherwise there's nothing that you'll see in benchmark/gaming FPS comparisons other than slightly better Min FPS. You really don't even need to push the CPU higher, imo. Share this post Link to post Share on other sites More sharing options...
