Cheapest CPU to reach 5 Ghz

verdenshersker · Jun 9, 2014

Hey Everyone,

What is the cheapest CPU to reach 5 Ghz?

I'm thinking some Athlon II or FX-4xxx or so.

Any processor that has a higher chance of hitting 5Ghz with one of the closed watercooled systems?

pigsinspace72 · Jun 9, 2014

fx-8350 with some good cooling and good motherboard. Intel 4790k @ 5ghz will defiantly out perform a AMD cpu at 5ghz but the 8350 is probably the cheapest you can oc to 5Ghz, maybe the 6300 but you may be stretching it.

djcm9819 · Jun 9, 2014

I would say some fx 43xx processor. I don't know if I got a "golden chip" but I can get 4.8 ghz on my fx 4350 with the stock cooling! If you want to be sure to reach 5 ghz stable buy an fx 4350 and some decent cooling.

Also remember you need a good motherboard to overclock a lot so also take that into consideration.

I think you're right. An FX-4300. But a 6300 is only like $10 more. I don't know older CPU's well at all though.

Okay that's some of the more expensive ones..

How far can I get on a Fx-4xxx or a Athlon II X4 750k or something like that?

iam2thecrowe · Jun 9, 2014

an i5 at 3.6ghz will probably still be faster than an fx 4xxx at 5ghz.
Is there some reason for wanting this 5ghz? because you can? Does it need to be stable at 5ghz or just boot to windows?

RookieOfTheYear · Jun 9, 2014

You should be able to get the 43xx to 5Ghz

amuffin · Jun 9, 2014

Any reason for 5ghz? Remember, clock speed isn't everything!

verdenshersker · Jun 9, 2014

Just think it could be fun. It's a friend of mine that want it, he even said an Athlon II X2 would be fine for him at 5 Ghz, but I said he should go for the 750K X4 instead.

How do you guys like this $600 budget machine?

I managed to get 2 gfx for Crossfire, SSD and WaterCooling for OC of the CPU

Theres a couple things that I would change. Don't crossfire 2 cheap graphics card when you'd get a better performing single unit. Your only storage is a single 240Gb ssd when you can buy a 2TB hdd for the same cost. You are probably not going to get much over clocking headroom with a micro atx motherboard. A cheap liquid cooler will be easily outperformed over an air cooler.

The biggest problem with this build is that the sockets aren't the same for the cpu is FM2 and the motherboard is FM2+.

verdenshersker · Jun 10, 2014

As far as I can read on the internet, the dual gfx setup here outperforms a single unit at the same price combined.
He need the fast SSD instead of the huge storage just for 3-4 games at the time and can always put in another HDD later for more space.
The Mobo is backwards compatible wit the Athlon X4 750K cpu (its been checked) on the motherboard manufactures' website.
Also that motherboard should do fine with pushing the CPU to at least 4.2-4.5 Ghz as far as I can see.

I really don't know where you found those "problem", because it is all something I'm aware off that is not really considered problems.

Here is the OC review of the Motherboard:
http://hexus.net/tech/reviews/mainboard/47777-asrock-fm2a75-pro4-m/?page=9

Here are the other gfx cards for the same price (~$140):

R9 270 (Non X) - $130:
http://pcpartpicker.com/part/powercolor-video-card-axr92702gbd5tdheoc

GTX 750 Ti - $120 (Can't be used with 2, since the mobo only supports CFX)
http://pcpartpicker.com/part/evga-video-card-02gp43751kr

R9 270X - $150:
http://pcpartpicker.com/part/powercolor-video-card-axr9270x2gbd5tdheoc

I don't believe any of these cards will outperform 2 x R7 260X in Crossfire. Correct me if I'm wrong.
And the last thing about the SSD, well it's about performance and speed, not storage, so no doubt should be here.

Theoretically, any overclockable processor can get to 5Ghz providing you give it the required voltage and cooling. In the real world however, resources, budget or know-how mean that cooling has its limits for most people.

I've no experience overclocking AMD processors so I'm basing my opinions on Intel, but the Sandy Bridge line is still considered the best for overclocking. My 2500k will comfortably reach 4.5Ghz on a 212 Evo, so with a custom water loop, 5Ghz shouldn't be much of a problem.

unknownofprob · Jun 10, 2014

some CPU's are better then others, as I lie the fact that not all CPU's OC the same. The good ones are clearly much better then the poor ones, poor ones can become unstable at 5Ghz is unlucky, but it depends on also all the other factors above.

iam2thecrowe · Jun 11, 2014

IMO 5ghz is too ambitious for a 24/7 stable machine. you would have a better, more stable system spending the money on a better cpu in the first place rather than the liquid cooling. I also agree, ditch the crossfire setup, yes in a few benchmarks the absolute fps may be higher, but with choppiness, worse game support, graphical anomalies and poor frame latency compared to a decent single card.

unknownofprob · Jun 11, 2014

iam2thecrowe :

exactly.

nikoli707 · Jun 12, 2014

the cheapest modern cpu would be the 760k, just strap a phanteks or an h100i on it and you should very easily get to 5.0ghz stable prime/ibt. but for that amount of money you would be better off just getting a unlocked i5 'k' processor and it will beat the pants off of the 760k@5.0ghz even at stock clocks.

I have the FX-8350 and it does 5000 MHz stable with a Asus Sabertooth MB and a Corsair H100i cooler. I render a lot of video and it'll go all day with the 8 cores maxed out. You will also need extra cooling in your case to keep the VCore temps under 70 degrees. I use Delta server fans instead of the stock Corsair fans. And a couple of 140 mm intake fans. Have fun!
