yazedad Posted February 11, 2008 Share Posted February 11, 2008 what should i overclock (or overvoltage i don't know the difference) to get benefit of the full ram speed with system stability thanks guys if there is anything that i need to mention about my system please tell me , thanks Link to comment Share on other sites More sharing options...

DerekT Posted February 11, 2008 Share Posted February 11, 2008 Are you looking to increase your DRAM bandwidth or overlock the entire system, both CPU and DRAM? What cooling do you have on your system? CPU/Case Airflow, DRAM cooling, etc? Link to comment Share on other sites More sharing options...

DerekT Posted February 11, 2008 Share Posted February 11, 2008 the entire system and i am using water cooling for the CPU and 3in 3out 120mm fans for the case OK. Now your DRAM modules. Can you remove one and tell me the version number. There are now four versions. 1xx, 2xx, 3xx, and 4xx. Link to comment Share on other sites More sharing options...
yazedad Posted February 11, 2008 Author Share Posted February 11, 2008 OK. Now your DRAM modules. Can you remove one and tell me the version number.

yazedad Posted February 11, 2008 Author Share Posted February 11, 2008 i went ahead without you and played a little i am now on 3.4 GHZ at 1.287v :) with FSB speed of 1512 MHZ it's not stable yet things that i don't know anything about need to be changed :confused: and bout this: SPP<->MCP Ref Clock, MHz = 100 my minimum in 200 ??? i will do the other stuff and see what will happen Link to comment Share on other sites More sharing options...

DerekT Posted February 12, 2008 Share Posted February 12, 2008 i should metion that i got an error with the bios when i bootup saying: "warning! Now System is in Safe Mode, Please reset CPU or Memory frequency in the CMOS setup" I can't read your posts. Please post readable graphic uploads. The system does not like one of your settings and is rebooting in Motherboard Safe Mode as a recovery measure. This could be due to many things such as overheating, overvolting, error in DRAM speed/timings, CPU speed, Low voltages, etc. At the settings I gave you, this should not be showing up. This leads me to think that you have changed some settings as you said you went ahead and did some clocking up. After setting to these values, save them and boot to the Memtest ISO. Allow for two full passes and if stable, enter Windows. Run CoreTemp and CPU-z. Post the Idle temps with CoreTemp, the CPU/Memory and SPD tabs. Then Run OCCT and post your CoreTemp results at stock after 15 minutes. I asked you to set as above and post the graphics of the results and you posted two entirely unreadable graphics.

yazedad Posted February 13, 2008 Author Share Posted February 13, 2008 sorry for that it was the Thumbnail here are the right ones : CPU-Z reading: http://img150.imageshack.us/img150/6798/cpuzreadingsis9.png CPU temps : http://img150.imageshack.us/img150/8089/cputempqe4.png i did exactly what you've told me i think the problem was that the CPU and RAM didn't have a suitable FSB that lead me to a question : is linking the CPU FSP and the RAM DRAM (in a synchronized mode 1(x4 quad):2 (x2 DDR2) is better? or that does nothing ? however, i did some some overclocking now : here are the new results :) : http://img144.imageshack.us/img144/5470/2ndtestpt2.png Link to comment Share on other sites More sharing options...
Wired Posted February 13, 2008 Share Posted February 13, 2008 Heh, just fixed the incorrect links while you were posting. And as for your sig, Bence needs to tweak his game, 4K PoM Pyro isn't bad, but I've seen better :) Link to comment Share on other sites More sharing options...

Clearly you have no problem with temperatures so now it is just a matter of matching your CPU overclock to a DRAM overclock. Isolate the CPU and test the DRAM to find your overclock of the DRAM. Once you have found your maximum safe (temps are important on those chips) DRAM clocking, then you find your maximum stable CPU overclock. Then you set for max CPU and max DRAM and test again for stability. Use OCCT for a quick 30 minute stability test and then use Prime 95 for your final 8 - 10 hour stability test. You seem to have a decent enough understanding of how to gain the overclock. Now you just need to meld the CPU:DRAM and work to gain stability.

yazedad Posted February 14, 2008 Author Share Posted February 14, 2008 can you tell me how to use Prime 95 i download it and it was super confusing then i download ORTHOS and it was simple to use however i didn't understand: 1- what the difference testes are? 2- what time should they be run for? 3- what about the Priority? 4- can i use the computer (normal or heavy use) while they are running ? thanks P.S knowing my rig what do you thing the highs overclock for both the CPU and RAM (i don't what to overclock the heck out of it, just some thing that pay of the water cooling and doesn't harm my components on the long time) Link to comment Share on other sites More sharing options...

Just set to Small FFT's (as long as you have memtested stable) and click OK. Run Core Temp as well to check your load temps. If you get stable at 8+ hours then you are fine. It is ok to do light computer use while you Prime but you do not want to be doing heavy use. Let it run overnight. http://www.softpedia.com/get/Others/Home-Education/Prime95.shtml Tutorial: http://www.hardwareanalysis.com/content/topic/65100/ As long as you run 4 torture test threads, then you do not have to worry about priority settings. P.S knowing my rig what do you thing the highs overclock for both the CPU and RAM (i don't what to overclock the heck out of it, just some thing that pay of the water cooling and doesn't harm my components on the long time) I would think that 3.6 - 3.8 should be the mark for that CPU when using water cooling. Depending on the chip that is. Some make 4.0 with good w/c. The DRAM? Well that is dependent on the DRAM. I have seen 8500's make 1200Mhz and some make 1100MHz. So it's a YRMV kind of thing. You need to test the DRAM yourself. Link to comment Share on other sites More sharing options...
