What this means is that if the CPU fans can move 80cfm then the case intake fans need to move at least 120 cfm when added together. Also, if the cooler fans can move 80 cfm but the case exhaust fans can only move 40 cfm,then it is a restriction and the hot air can not get out.

Well I have two CM Sickleflows on the front intake, a Sickleflow on the bottom as an intake and the same fan type again on the back as outtake, then 2 140mm Sharkoon fans on the top as outtakes, and I have all the case fans hooked up to a Fan controller. My temps on my current CPU only get up to about 53C when gaming and thats with all case fans set to low speed through the controller. The CPU cooler fans are set to be controlled by the BIOS's fan control and they do a good job of keeping everything cool. I should be okay I think.

The CPU has been ordered! Should be coming soon!

Hm. That front Sharkoon would be better flipped to an intake and the rear Sharkoon is most likely doing nothing. If the case exhaust fan is powerful enough then you should be ok. Note that I removed the rear of my case and have no exhaust fans at all. Just a big hole. Look at the pics in my sig rig to see my evolution.

The CPU arrived, and WOW! Its made a big difference, on SW:Battlefront, on the Endor map, I was getting around 30-40 FPS and now with this CPU, I'm getting 60-80 FPS on the same settings! I can finally take the settings up a bit now instead of staying on Low. GTAV is also running much better, still need to test out BF4. I guess my GPU isn't being held back any more!

Im really surprised at the stock voltage for this CPU, I haven't done any overclocking yet, everything is set to Auto. My chip's VID is reported as 1.288v in HWiNFO64 and in CPU-Z its reading 1.288v-1.296v. Does this mean I have a good chip?

Ill try overclocking soon once I've read into it enough. Pretty excited to see what it can do!

Thanks, Ill try out flipping the fan around, I have all of the fans pointing the way they were when I bought the case, I just assumed they were setup right.

Oohh you got a good one! thumb.gif That is the same VID as my good 8370. Here are some pics of how it performed on my GD80.

This is with everything on auto except turbo and the ram settings.

Then I set the vcore to as high as the stock bios would go which is 1.45 v.


Then this is as far as I could take it with the good CC and CBII.

Also, i have learned that two top fan are not needed with air cooling. Just the one in front feeding air to the cooler. But experiment one your system!

1.28v for 4Ghz is the best undervolt i can do on my 8320. So you got a low leaking chip, which most probably means that at least up to 4.5, you are guaranteed to have lower than normal voltage requirements (less heat). Past 4.5 you will either hit a wall or go for 5Ghz.

Don't worry about BF4, it uses 8 threads, even if they are not heavily loaded. You are still bound to have better fps than before.

That's probably as good a match for the motherboard as you could have. Do you know what batch number your cpu is? " pgn 1235" it should look similar to that.

Sweet! Wow, nice job on getting 4.9 Ghz, thats some high voltage though biggrin.gif The highest the bios will let me set the voltage is 1.44v and when I check with CPU-Z, it reports only 1.40 so im guessing this is that vDroop ive seen people talk about online with this board. If I use control center, I can use the higher voltages. I'm on the latest bios V13.6.

Im well chuffed, ill overclock it when I have some spare time. Id be happy with 4.5, anything more would be a bonus smile.gif Yeah, your right, On BF4, I was getting over 100fps on low settings, bumped everything up to high and its still very smooth, around 60-70fps. Star Wars Battlefront is averaging the same kind of FPS too, both Frostbite Engine games. It shows how bad my old CPU was and how much it was holding my performance back biggrin.gif

I'm guessing I can only find out the batch number by looking at the top of the chip? I should have took a photo before I put the paste on and put my heatsink on tongue.gif.

Congratulations for the new CPU! Glad to read that you got a nice FX, really good VID.

Quad cores are starting to become more and more saturaded theses days.

As we all know, most modern game engines today love cores. The eight threads of the Vishera are becoming more and more appealing thees days.

Look this test:
https://www.youtube.com/watch?v=r8UYYTcG_yk

The 8 thread FX CPU´s aged very well. I believe that even after Zen is out, and even being a dead plataform, the 990FX and Vishera 8 thread CPU´s will handle some good gaming for the next years.

Quad cores are starting to become more and more resourceless by now. Have a friend with a stock low clock i5 4440 3.1 Ghz and R9 290X. In Crisis 3 his CPU is 95~100% while gaming 1080p. His GPU dont run 100% at some levels in the game.

I have a weaker GPU, R9 280X, but it´s always maxed 100%. The CPU use is also much lower, like max 35% os use. All 8 threads loaded.


Good Luck with the overclock results, be sure to cool down your VRM since now you are running a 125W part.

Don't pay attention to voltages, pay attention to temperatures. Because of vdroop the vcore may look high but under 100% sustained loads it is not so bad. You should end up with a nice gaming rig.

So I'm about to try some overclocking but I'm a bit confused which settings I need to change in the BIOS before proceeding with Control Center, I have set the CPU, NB and HT Multipliers to 20x, 11x and 13x respectively. I have tried to set all the voltages to what I believe to be stock based on readings from Control Center with everything in the BIOS set to Auto. Some of them are coming up lower when I look in Control Center. The CPU voltage is set to 1.3v in the bios and in Control Center, its come up as 1.26v which is even lower than my stock VID. I also set the CPU NB to 1.175 and Control Center shows 1.164.

So with the voltages, which should I set in the BIOS and which should I then adjust in Control Center? Or should I just leave them all on auto in the BIOS and just use control center to set the voltages?

As for my temps, well before Ive done any overclocking, they look fine, I was playing Battlefront and the CPU was at 46C, (i know thats not full load but I will test more once I've got these voltages/settings locked down)

Im following these guides roughly, I'm just planning on upping the CPU multiplier and voltages and my target is 4.5 Ghz, ill go higher if I can.
