Question about CPU/RAM Overclocking with voltages.

So first of all, here are my specs:


GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD
AMD FX-8320, overclocked to 4.4 GHZ (40C underload).
EVGA 04G-P4-2766-KR GeForce GTX 760 4GB 256-bit GDDR5 PCI Express 3.0
G.SKILL Sniper Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400
Rosewill CAPSTONE-750 750W Continuous @ 50°C, Intel Haswell Ready, 80 PLUS GOLD
Samsung 840 Pro 128GB SSD
Western Digital Blue 1TB 7200 FPM 64MB Cache SATA 6.0Gb/s 3.5"
Seagate Barracuda 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5"
ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner
CORSAIR Hydro series H80 High Performance Liquid CPU Cooler
Cooler Master Elite 430 Midtower Case

=============================================================

Whew now down to my probm, my RAM is getting it's butt kicked by much much much worse RAM cards on benchmarks and I have no idea why!

Yes my RAM is 2400mhz ram, my Mobo supports up to 1866mhz, however if I clock at 1600mhz everything works fine, so I was wondering is anyone knew ithis was the problem or not or if anyone knows how to fix it?

Do I change the HT LINK voltage?
Cpu Vcore voltage?

There's SO many voltages it drives me insane and I don'r want to break anything.
---------------------------------------------------------------------------------------------------

My second and LAST question is, for some reason I can only increase the clock on my cpu from 3.5 -> 4.4 ghz and would like to go higher than that as I see people getting 4.7-4.8.

Anyone. can someone tell me which optional I select and how to adjust the voltages? I'd greatly appreciate it!

To all of you who read everything I wrote I applaud you, however I will even applaud harder for the people who help me out :).

Thank you@

  1. Best answer
    What are you overclocking, the FSB or the Multiplier?

    If you are only overclocking the multiplier, just decrease the timings on the RAM and it should work fine,.

    I have the 1866 G.skill running at 1866, with a .05 voltage increase and stock timings (10-11-10-30). 8350@ 4.8

    You shouldn't need to worry about anything except the CPU multiplier and the CPU voltage. You can leave the rest alone for the most part.
  2. Can you give me an explanation? My BIOs doesn't look anything like the BIOs I've seen other people talking about.

    Thanks for your time!

    It's probably a EUFI bios.

    There should be a sticker on the RAM stick with the recommended timings, usually looks like 10-11-10-30, or 9-9-9-28. Depends on your RAM.

    In the BIOS will be a RAM timings sections, the first 4 from the top should be set to the match those timings. The FSB will increase the speed of the RAM, so it's best just to overclock the Multiplier unless you are more concerned with benchmarks than stability.

    I can't really tell you what will/will not work, it's a lot of trial and error.
    You'll have to keep bumping the settings up and retrying to really get a good result. What works on one setup may not necessary work on another. It various from processor to processor, from 1 RAM stick to the next.
