Crylon Posted March 21, 2012 Author Share Posted March 21, 2012 running oc @4.2ghz what do you think? Especially about the temps. Is it normal that it switches from 3.3ghz to 4.2ghz during the stress test? I thought that once its under stress it stays at 4.2ghz Link to comment Share on other sites More sharing options...
jeffk Posted March 21, 2012 Share Posted March 21, 2012 Crylon, As i said on the Corsair forum, i set my vRam to 1.6v and the is stable @ 1866mhz with XMP Profile. Look at attachement. Don't watch out/cry about my CPU temp, its because I maxed my vCore to the max to be sure that it was not a CPU issue. http://pix.toile-libre.org/upload/original/1332351999.png So now you have choice to run @ 1600 8-8-8-24 @1.5v or 1866 9-10-9-27 @1.6v. I go back at the other forum Crylon ;) Link to comment Share on other sites More sharing options...
peanutz94 Posted March 21, 2012 Share Posted March 21, 2012 running oc @4.2ghz what do you think? Especially about the temps. Is it normal that it switches from 3.3ghz to 4.2ghz during the stress test? I thought that once its under stress it stays at 4.2ghz Crylon, you didn't mention that you were overclocking the CPU as well as the memory. That would have changed things. Did you try running the memory with out the overclock? At 1866? Just OC the memory there really should not be any need to increase VCORE, just memory buss and VTT. But with the CPU overclocked you may have to sacrifice RAM speed for CPU speed. Which really isn't a sacrifice. You'll get a better performance boost from the increase CPU oC vs the RAM As long as you are stable now, your temps are fine. What are they atload? @Jeff, he memory controller is not on the motherboard anymore. They now resid on the CPU which is why i gave Crylon the information i have. The kits should run at 1866mhz without an overclock on the CPU side of things. But if you are overclocking as high as you are you will probably going to sacrifice RAM speed for CPU speed. To add to this yes , you need to add QPI0VTT which is memory controller voltage. If your kit will not run a 1866mhz WITHOUT an overclock at the rated voltages then you can RMA the kit. But if you recieve a second kit that does the same exact thing then it most likely the CPU's memory controller not being strong enough to run memory that high. The I-5'sare known for not being the best overclocker to begin with. As far as RAM goes. Link to comment Share on other sites More sharing options...
Turbonerfs101e Posted March 22, 2012 Share Posted March 22, 2012 hi Did you update bios to last version 1.30 As it improve stability and compatibility Support for XMP ver. 1.3. start with bios version 1.10 Hope this help Sincerly yours Link to comment Share on other sites More sharing options...
jeffk Posted March 22, 2012 Share Posted March 22, 2012 Hello, You are talking to who ? Me with my Gigabyte mobo à Crylon and his Asus ? I'm running with bios F6. Link to comment Share on other sites More sharing options...
Crylon Posted March 22, 2012 Author Share Posted March 22, 2012 @peanutz: yes, at first I only tried ocing the memory leaving the cpu on auto.Now that I have a stable ram oc with 1600mhz 8-8-8-24 2T 1,5V I moved on to oc the cpu which is now running at 4.2ghz! @Turboner: yes I'm running bios version 1.30 Link to comment Share on other sites More sharing options...
jeffk Posted March 22, 2012 Share Posted March 22, 2012 peanutz94 was right, I apologize. Tested with QPI/VTT @ 1.12 and vRAM 1.6, still not working. Even with a boosted QPI/VTT the 2500k cant handle it, its working with the vcore @ 1.4, but for 4.2ghz, its ridiculous. So : I passed the test with : QPI/VTT 1.05 vRAM 1.5 Freq : 1600mhz 9-9-9-24-2T (i ll test 8-8-8-24-2T) And decent vCore. I Wish you good luck for your CPU OC ;) Link to comment Share on other sites More sharing options...
Turbonerfs101e Posted March 22, 2012 Share Posted March 22, 2012 If you set memory at 1600Mhz And you OC CPU after, memory run more then 1600MHz after that Runing at 8-8-8-24 could give you BSOD As memory test at 9-10-9-27 If it run stable like this it is ok But is u still ave some issue 1- Set bios as default 2- activate XMP profile 3- set memory as manual to keep XMP latancy setting 4- set memory at 1600MHz 5- OC CPU This way you ave XMP latancy setting at 1600MHz U could OC CPU to keep memory lower then 1866MHz to keep it under factory testing speed Hope this help Sincerly yours Link to comment Share on other sites More sharing options...

Turbonerfs101e Posted March 22, 2012 Share Posted March 22, 2012 yes but if u OC CPU with host clock fequency Then QPI and memory Speed will incress If u are using mutiplier boost ratio Then it ok As uit dont afect QPI and memory Speed Link to comment Share on other sites More sharing options...
jeffk Posted March 22, 2012 Share Posted March 22, 2012 I'm on 1155 socket so, I only touch the ratio, not the BCLK ;) Link to comment Share on other sites More sharing options...
Turbonerfs101e Posted March 22, 2012 Share Posted March 22, 2012 Then if it stable You ave finde the optimal OC for your PC Link to comment Share on other sites More sharing options...
Crylon Posted March 23, 2012 Author Share Posted March 23, 2012 jeff, you should be able to run 1600 at 8-8-8-24, check out my configuration settings. I tested it for a long time and it remains stable! Link to comment Share on other sites More sharing options...
jeffk Posted March 23, 2012 Share Posted March 23, 2012 Thanks, I'll try 8-8-8-24, Because i'm now stable @ 4.2ghz, 9-9-9-24 default Vram and default QPI/VTT. I'll try asap 8-8-8-24 @1.5. By the way, I'm now stable @ BF3 also, and i dont crashed since. :D Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 23, 2012 Corsair Employee Share Posted March 23, 2012 What is the MB BIOS version of your MB jeffk and Crylon is the thread owner, but I cannot get on Asrocks site seems they are doing something? Link to comment Share on other sites More sharing options...

jeffk Posted March 26, 2012 Share Posted March 26, 2012 I have a Gigabyte z68xp UD3P B3 (running under bios F6) My ram will stay @ 9-9-9-24 1600mhz @ 1.5, because she is not able to run @ 8-8-8-24 1600mhz. @ 1.5. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted March 26, 2012 Corsair Employee Share Posted March 26, 2012 Jeff Crylon is the O.P and when we answer a post we will normally address the thread owner or O.P. In this case should be Crylon. If you have a an issue it would be best to start your own thread so things do not get confused. Link to comment Share on other sites More sharing options...
