Would like to overclock.

post #1 of 18
Thread Starter 
I just built my first budget gaming PC with the help of my friend mostly to play Starcraft 2. So i built the PC, installed Starcraft 2 and tried it at ultra settings, in 1v1 battle my fps went down to 15 fps at lowest so i figured i couldn't play at ultra. I was wondering if overclocking would increase my fps by a decent margin by using the stock fans i already have while keeping it cool. If this is possible, i'd like to know if there is a easy guide to use to overclock since i would have no idea what i'm doing. I'd like to overclock my cpu and gpu, here is my build:

ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner - Bulk - OEM

COOLER MASTER ELITE 335 RC-335-KKN1-GP Black SECC Steel ATX Mid Tower Computer Case

Antec NEO ECO 520C 520W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC

Western Digital Caviar Black WD5002AALX 500GB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive

ASUS M4A77TD AM3 AMD 770 ATX AMD Motherboard

A-DATA 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Dual Channel Kit Desktop Memory Model AD3U1333B2G9-DRH

AMD Athlon II X4 640 Propus 3.0GHz Socket AM3 95W Quad-Core Desktop Processor ADX640WFGMBOX

ASUS EAH6850 DC/2DIS/1GD5/V2 Radeon HD 6850 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

i think you might consider changing that processor, probably major bottlenecking is happening anyone agree? because having a 6850 should not be getting 15fps

because lack of engery/being lazy to type up the whole process here is a

that should help with basic overclocking, also buy an aftermarket heatsink beacue clocking any cpu with stock doesnt get you anywhere

to oc gpu should get you along fine

So i absolutely need a better fan to overclock my cpu? Do i need another fan if i want to overclock my gpu? Also when i played Starcraft 2 at extreme settings it starts out at around 55-60 fps at 1080 resolution, but when i build 200 man army and go destroy something its when it goes down to around 20 but it did go as low as 15. You think its my cpu?

Thanks for the vids, i'll check them out.

well if you have plans to reach really high clocks yes if not and reach like mild clocks then no, and no you dont need it for gpu most of those fans can handle it; i am not 100% sure is cpu bottlenecking but i think with out a reasonable doubt that could be the issue

Be prepared to be held back from overclocking due to two factors:
1. Athlon II x4 640 simply doesn't overclock well. My friend with this processor hit a wall at just 3.5Ghz.
2. Generic 1333 CL9 memory + ref clock OC-ing = will definitely hold you back.

So will i be able to overclock it to 3.5 or not even because my memory isn't good enough? I saw some videos of some people overclocking it to 3.8 ghz but that was probably with a better build, i don't mind if i can get to 3.5

Starcraft 2 is a poorly coded game. It only takes primary advantage of a single core and so only scales with clock speed, not with core count. Dual cores will perform similarly to quad cores in SC2, and AMD chips lag behind intel chips as well.

The slowdown in battles is most definitely a cpu limitation. Overclocking your processor will help, though an aftermarket cooling solution is recommended to control temperatures.

Here is a good article from anandtech on overclocking the x6 and starcraft 2 performance. Note the 43% fps increase overclocking from 3.2/2.0nb to 4.0/3.0nb.

For that price an overclocked i3 dual core would outperform the quad core athlon ii x4. The athlon ii x4 will shine in other non blizzard games, such as bfbc2, cod, and the bioware games.

So if i was going to buy another fan is there any good suggestion for a good one that isn't too expensive? Also xd 1771 said "2. Generic 1333 CL9 memory + ref clock OC-ing = will definitely hold you back." I don't really know what that means but will it stop me from overclocking it to even 3.5?

I was thinking of buying the i3 but it was more expensive and i was also thinking that in the future a quad core would serve me better purpose. I didn't think the difference in playing Starcraft 2 would be huge though (are they?). If they are maybe i should have went with that i guess.

It'll stop you from overclocking to 4, but 3.5 looks like it won't if you use 250Mhz bus clock and x5.33 multiplier, to run at rated setting of 1333Mhz. This will allow up to 3750Mhz CPU.

I'd be happy with 3.75, i've read this fan was good would it be good for me?
COOLER MASTER Hyper 212 Plus RR-B10-212P-G1, aslso if i OC the GPU and CPU do i need to add any extra fans?
