Asus Rampage V Extreme, i7-5930K with 3400MHz RAM upgrades
Hello there
I finished up my new pearl and got to the point I want to OC and there I got stucked.
My Specs are :
Case : Lian Li PC-07OS
MoBo : Asus Rampage V Edition 10
CPU : i7-5930K
CPU Cooling : Corsair H100i v2
PSU : Corsair RM1000i
RAM : Corsair Vengeance LED 32GB RAM (4x8GB) @ 3400MHz
GPU : Asus GTX275 (Yes... waiting for my GTX1080 xD )
Storage : Samsung 950 PRO m.2 SSD
I have started to OC my CPU and got 4400MHz @ 1.3V stable with BCLK @ 100. Everything tested via Aida64 and ROG Realbench.
So now I have to get my hands on my RAM modules and there is where I stuck. If I enable the XMP profile it changes my BCLK to 170 and my Multiplier to 22 = 3740MHz
I read that BCLK shouldn't go above 125. Is it true ? Can you help me and OC my system properly ?
Is there any danger getting such high base clocks ? Do you recommend any other settings to archive maybe 4.5GHz ?
My actual temps at full load are not reaching 73c.
Many Questions
There is a configuration named 'CPU strap.' It helps prevent the PCI-E bus from being overclocked when the BCLK value increases. When the strap and BCLK align, the system remains stable similar to a 100MHz BCLK. For this setup, a CPU strap around 167 seems appropriate with a BCLK of 170. The calculation shows a similar overclock level for a 101.8MHz BCLK, which is generally acceptable.
WoW ! So if I turn on XMP, set BCLK to 170, adjust the multiplier to 26 (which is 4.420MHZ), everything should work? Do you think I need to tweak the vcore again or keep it at 1.3? Edit : 170*167/100 = 101.8... That was confusing :S
It should work just fine.
Apologies if I wasn't able to clarify the math more clearly.
I also observed that increasing the base clock resulted in significantly elevated temperatures, around 5-6°C.
Consider increasing the system agent voltage to 1.2. The 3400MHz RAM will be challenging for the Haswell-E memory controller without adjustments—please note I should have mentioned this sooner. You may need to adjust to 3000 or 3200, or use more relaxed timings, but try my recommended settings first.
