i bought an 8350 and a motherboard, without the ram and thermal grease so i can't use it. i am starting to get worried because i bought the mobo a while back on impulse and can't return it, and i have read that motherboards can limit overclocking for certain reasons like heat and the mobo only being able to handle certain voltages wattage's etc.if i'm wrong tell me. so anyways my mobo is a m5a97 le r2.0. i might be getting the corsair h100 because of the $70 refurbished price. so what kind of oc'ing can i get done here. suggestions for better parts to squeeze out the mhz if anything isn't good enough.
4.5 to 4.6 easily on a h100, maybe even 4.7 to 4.8.
I think 4.5GHz to 4.6GHz is a reasonable estimate with that motherboard.
Think you would be able to get at least 4.6ghz. if you get there, Post some temperatures &voltages (stressed and non stressed). Maybe we then we could see if youre able to push it higher :)
(I really think with your h100 is up for more)
I totally agree, but I don't think the VRM on a 970 board is good enough to push that higher...Maybe. I got a 6300 that was able to do 4.2 on a 970 board from Asrock
Asus M5A97 Le R2.0 4+2 powerphase , but no heat spreader on the VRM´s i think you will probably have your ansewr.... you will no reach high numbers without having the risk to burn your board. i would recommend a better board. i think even at stock clock your vrm´s etc will get hot. because there is no cooling on them at all.
WOW, ok, Didn't see the powerphases have a heatsink. Anything above 4.4 is going to put the VRMs of the powerphases to the test!
Hey guys, I hope you don't mind if I chime in with a recent purchase I've made. I bought a FX 8350, Coolermaster Hyper TX3 Evo cooler and a £60~ MSI 970A-G46 AMD 970A 4+2 phase motherboard. I intended on eventually overclocking the 8350 to unlock its full potential, but I read horror stories online that the MSI board I purchased just wouldn't cut it when overclocking due to very poor cooling and the limited phase power design.
I swapped out that board and upgraded to the follow board this weekend:

I love Asus boards, and this has a much more robust cooling solution as well as 6+2 phase power and more precise bios overclocking options (increasing clock in single mhz increments).Unfortunately, due to my HD 7950 PCS+ being DOA, I haven't had a chance to test this setup yet, but I was wondering if anyone here has tried overclocking on a similar air cooled setup? I was hoping to reach at least 4.5ghz comfortably.
You will. It has nice heatsinks and phases. Youd get to 4.6 without problems, if the cooler is up for it (I think only to 4.5 though)
Next time create a seperate topic, its not really nice to drag the attention away of the current topic :)
Thanks bud, will do.
The Msi 970A- GD46 has only a 4+1 powerphase, and not realy great vrm´s and mosfets. so i would not overclock if i was you, those 970´s boards are all just not made for that powerhungry FX 8 core cpu.this board in particular has very well known overheating mosfets and vrm´s issues. its never a good idea if you want a power hungry FX 8 core, to cheapout on a mobo. the best way is to buy a Decent 990FX chipsetboard. like the Asus M5A99FX pro R2.0 i will post a list again.
Mobo´s for overclocking FX8350/FX8320.
- Asus Crosshair V Formula Z 8+2 powerphase digi vrm
- Asus Sabertooth 990FX Gen3 8+2 powerphase digi vrm pci-e 3.0
- Asus Sabertooth 990FX R2.0 8+2 powerphase digi vrm
- Asus M5A99FX pro R2.0 6+2 powerphase digi vrm
- Asrock 990FX Extreme 9 12+2 powerphase digi vrm
- Asrock 990FX Fatality 12+2 powerphase digi vrm
- Asus M5A99X evo R2.0 6+2 powerphase digi vrm (only 20 pci-e lanes
- Asus M5A97 evo R2.0 6+2 powerphase digi vrm.
grtz Angel ☺
Yeah,
For using that h100 200%; +1 on any asus motherboard posted above (Pick the sabertooth R2, it had a pricedrop in my region). It is really worth it, those asus board clock a hell of alot better, I promise.
Do it for your watercooler, its begging to get hot :)
I had my FX 6350 on a m5a97 and I was able to hit 4.6GHz, I upgraded to a Crosshair V Formula and I was able to hit 5.0 GHz but I keep it at 4.7GHz. The sabertooth would be similar, just make sure you OC with the UEFI and not AI suite II. AI suite gave me all sorts of instability when I was testing different Overclocks.
an open box asus sabertooth is $135 does anyone have any bad experiences with open box at mobos, because this seems a good way to go
Mobo should work fine, but dont be surprised if it is missing sata cables, crossfire/sli bridges, and various other things that are supposed to come with it.
i can live with that
I got my 8350 to 5.02 Ghz with and H100i, and an Asus M5A99x Evo R2.0. not sure exactly how good the M5A97 LE R2.0 is, but it has to be decent since it's from Asus.
I have my FX 8350 running at 4.6 with a H80i and it's around 64 degrees on load. Don't really want to push it any more, but I was able to get it up to 4.8 with 1.45V before the temperatures started causing shenanigans.
I was only able to reach 4.6 before reaching a voltage wall (ie had to go crazy to get any more GHz)
CAREFUL! 64 C is definitely at the top end of the safe temps for the 8350!
