Is it worth disabling hyper threading for the sole purpose of heat and stability while stress testing? Then re-enabling it once a stable clock is found? I understand ht produces extra heat, especially while stressing. Seems logical that removing that variable during stressing could only help the situation as you're never going to get anywhere near that much heat in real world applications

Looking for a little help here I have been running my 2500K at 4.5MHz for over a year now at least maybe even two forget when I got it. Anyways I was running 4.5 at 1.35 volts chip is not great at all now I had my 1600 ram kit one stick went dead so got a 8GB 2133 on a really good deal like less then 8GB 1600 kit. Now my problem is I am having to run 1.41 volts to get 4.5 stable again. Now I did not test the overclock with the 1600 ram for months now and maybe my chip was unstable then also after this time but I never had any blue screens or anything until the ram stick went and the PC was just frozen.

I have never pushed this chip vary hard as I always had problems getting past the 45 multiplier it was weird stuff but now I have know problems getting past it but I'm taking these higher volts to get 4.5 stable is it it the ram speed now that killing me. I have all my PLL and other volts all on auto have not played with them yet to maybe get a higher overclock at these volts but 1.41 volts at 4.5 maybe the worst 2500k in the world LOL. Any ideas input would be super cool thanks.

It would probably be a good idea to post screenshots of your bios. Format a flashdrive in fat32 reboot into bios and hit f12.

Are u running offset or fixed?

I was running offset but it did not seem right also the bios would say i was at say 1.36 but in Cpu Z I was showing 1.41 and I did try 1-5 on the calibration stuff and never got close. I just think something is wrong with my 2500K as now I updated my bios and even before updating I cant get my cpu to down clock at idle. I have everything 100% stock setting in the bios and my volts drop to like 1.00 or whatever but my cpu stays at 3.3MHz I cant understand what the deal is something is 100% not right

Ok Well just found out the last couple of versions of CPUz do not show the CPU downclocking just a FYI for people if you also get to looking and think something is wrong running version 1.60 right now and it works fine.

Ok I will get some screen shoots up soon I updated my bios as they where back when the motherboard first came out so maybe I will have better luck always had problems with the bios so we will see.

Only problem is when you then enable HT the stability is unknown (and untested smile.gif)

Do you now run with a RAM clock of 2133 instead of 1600, or with the same settings as before exchanging the module? If you're at a higher clock, the IMC (integrated memory controller) might need more power to handle that higher frequency, which could explain why you suddenly need more Vcore.

I tried adding +10 and it's still happening. Maybe it's the games...?

Games are BFBC2 and BF3 that are causing the errors. It happens typically when the game crashes... in the exact same moment.

Is it possible for an unstable GPU OC to cause WHEA errors? That might be my issue... rolleyes.gif

I dont remember seeing an answer to a previous question: I know IBT isnt as good as P95, but how good is it for a quick stability test?
post #5549 of 9531
IBT if fine for a quick stability test. Some might even use it as their main stability test. I personally don't use it because of how hot it gets the cpu compared to p95 but its up to you just watch your temps

Do you now run with a RAM clock of 2133 instead of 1600, or with the same settings as before exchanging the module? If you're at a higher clock, the IMC (integrated memory controller) might need more power to handle that higher frequency, which could explain why you suddenly need more Vcore.

Sorry my typing is really bad I will try and make it easier to read. Anyways I did start my overclock 100% over with this new ram at 2133 and I do understand it may need more Vcore. What I really don't understand is if Vcore directly connected to the memory controller or is one of the other voltage settings control that? I also seem to be having problems with LLC and offset voltage as I ran prime95 for 10 hours all passed this morning and I load up World of Warcraft and I got a blue screen. Now when I was playing wow I had CPUz open and the CPU was clocked up at 4.5GHz but I only had 40% cpu usage so CPUz was only showing volts hitting 1.29 and not the 1.37 I had with prime loaded. So what it comes down to is I think I'm doing something wrong with LLC and my off set voltage like I don't understand 100% how it works maybe.

I'm really just looking to get 4.5GHz-4.7GHz stable with out braking the 1.4 volts. I have a really good custom water cooling loop so my temps like the highest I have ever seen is 63c but normal is around 55c so temps are 100% in check. I guess I'm just looking for someone that can tell me is this 2133 RAM holding me down and making me have this higher Vcore or can I up another voltage and understand LLC and offset voltage settings better to help.
