Queiroz Posted October 21, 2010 Posted October 21, 2010 Hello guys. I'm looking forward to OC my new computer and i come here once again to ask for your advices. My first and only OC is with my E8400 @ 3.6 with Gigabyte GA-EP43-DS3L but it was 2 years ago. I was looking to buy a new Gigabyte board for my system but almost every P55 board got problems with USB3 or SATA3 and this time i chose Asus and i hope i will not regret my decision. The Turbo mode is activated and i didn't find the option to disable it on the Bios... I thought it was the [Turbo Profile] but there are no other options there... My goal is to achieve 4Ghz stable enough to stay up for 24/7 just changing the multiplier and the memory @ 2000Mhz BIOS images below. If there are any other images necessary just tell me. New rig: Core i7 875k @ 2.93Ghz (CoolerMaster V8 + Artic Silver 5) Asus P7P55D-E Deluxe @ BIOS 1301 4GB G.Skill DDR3 2200Mhz (F3-17600CL7D-4GBPIS) Gigabyte GT 240 SSD OCZ Vertex 2 120gb PSU XFX 750 Black Edition Modular Case CM HAF 932 UPS APC BR1500 Any advice will be very helpful. Thanks. My Best Regards, Queiroz Share this post Link to post Share on other sites More sharing options...
GabrielT Posted October 21, 2010 Posted October 21, 2010 (edited) Well you wont be able to 2 of the things you want to do. If you want to get your ram up that high you will need to select the highest memory multiplier (on my board that is 10) and a core clock of 200. If your mobo has a higher multiplier go you. Secondly you would have to have a very nice chip to run that memory that fast without a decent boots to the QPI and VTT voltage but you will have to up those slowly on your own. What I suggest you do is work on getting the CPU to 4GHz first, leaving the RAM at a low speed 1000-1600MHz just for simplicity of overclocking. Once you get up to 4GHz work on the ram by itself, lower your clock speed to around stock to take it out of the equation if you runinto instability. You sir are about to become very friendly with your Bios, we can't set everything up for you. Remember, 1.45v is the normally the agreed "safe" Vcore voltage on the i7's. 1.65 is the max ram voltage without raising the QPI voltage. Don't raise the QPI voltage without proper cooling. By the way, the Coolermaster V8 should be able to handle that chip at 4GHz as long as you can keep the voltage down. Watch your temps with your new rig.

I just started the OC test and i have set 24 x 167mhz and the memory 2004Mhz (2:12) Vcore: 1.30 IMC: 1.30 PCH: 1.05 PLL: 1.80 DIMM: 1.65 I leave turned on just the prefetcher, prefetch, All cores and HT. I saved and rebooted the machine. The boot went fine and as soon the windows booted i opened CPU-Z and it shows 4019Mhz on the Core Speed and 1004Mhz (2:12) on the DRAM Frequency and it's normal at the moment but the big problem is the temperatures because it's 48ºC idle and i opened RealTemp and LinX (memory run 3 times) and as soon as i started the test the temperatures went very high 92ºC and i got worried and stopped the test because i believe this is beyond normal, right? What should i do? Maybe Thermal compound application was not correct? Just one dot in the center of the CPU.

AIinc Posted October 22, 2010 Posted October 22, 2010 One thing is AC5 has been around for a while now and there are better thermal compounds you can use! Although, just using a better thermal compound, wont bring your load temps down 30C! For the compound, I would highly recommend using MX-3, it's one of the best I've ever used. I would start by dropping your overclock to 3.6GHz, and just let the ram run below spec speed. Drop your vcore to 1.225, and see if it boots, if so, then run your stability test again and monitor your temps closely. This is just my opinion, but to me, the CM V8, is more of a mid range cooler, and to run stable at 4GHz, your gonna need one of the top rated air coolers, to have good temps! Another thing to check is to make sure that your cpu cooler is mounted correctly! Share this post Link to post Share on other sites More sharing options...
Queiroz Posted October 26, 2010 Posted October 26, 2010 Goodnight everyone. Sorry for not giving news but I've been researching and it's been almost two years since the Arctic Silver 5 was stored inside the motherboard box in my closet and was not even with the tip down as indicated. So I decided to buy the Arctic Cooling MX-4 and ArctiClean kit at Performance-PCS and also took the opportunity to buy four 120mm fans Cooler Master R4-L2R-20Cr-GP and 19db 90CFM to install in the side of the HAF 932 and it will arrive here by the 15th of next month and then I will reapply the thermal paste and do the tests again and i hope this time it will improve a little more ... Thanks for the help guys! My Best Regards, Queiroz Share this post Link to post Share on other sites More sharing options...
GabrielT Posted October 26, 2010 Posted October 26, 2010 Alright man your board seems to kick the crap out of mine Keep it up, oh and when I say stuff and I was wrong it was just to make sure you were paying attention. Share this post Link to post Share on other sites More sharing options...
