Would a FX-8350 be a worthy upgrade? - Page 3

post #21 of 29
Fist off, be sure that you have a proper cooling in the CPU and a good quality PSU. Also, it´s always a good ideia to install a FAN in the VRM heatsink of the MotherBoard, to avoid toasty/throtlling problems.

Be sure to have good air flow in the case. It´s very important a correct air flow to remove the heat from the case.

So lets go.

1° - Make a Full Clear CMOS in the MotherBoard jumper. Let´s start from ZERO !

2° - Reconfigure the BIOS basic (date, boot). Disable C1E, Cool ´n Quite and all energy saving devices.

3° - Increase the CPU multiplier step by step with small increases in clock. Example: | CPU STOCK = 200 * 21 = 4200 | CPU OVER = 200 * 22 = 4400 |. Also increase a noth the CPU voltage.

4° - Increase by 0.1v / 0.2v your NorthBridge and HTT Voltages.

5° - Run stock clocks in the memory for now. But overvolt it a little, if stock voltage is 1.5v, increase to 1.6v. @ 1600Mhz minimum clock.

6° - Enter Windows and test the CPU with IntelBurn in test for five cicles or at least 30 minutes. Check your CPU and socket temps, maximum is 70°c.

7° - If tests fail enter BIOS again and add a little of voltage in the CPU.

8° - Do the steps above until reach your termal CPU / Socket limits.

9° - Monitor your temperatures with HW Monitor or HWiNFO64.

Always increase voltage and clocks by small amounts. Do not make large jumps it´s difficult to stabilyze the hardware and is a risk.

Good Luck !

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.

That is generally good advice,but this motherboard is the MSI GD80. It is a different animal entirely.

First turn off the OC Genie and turbo. I always left CnQ on. This upsets others but it doesn't bother the GD80 at all.

Leave all voltage settings on "auto".

Concentrate on the ram first. I forget what you have but I set my G Skill ram to 1866 and then try all of the presets until I find the one it likes best. Then set the ram voltage over 1.6v. MSI says that this improves stability.

Now just start bumping up the multiplier and vcore (cpu ratio and cpu voltage) and stress testing for stability. Watch your temperatures! That is a cool running motherboard and it will help the cpu run cooler too. Don't bother with CC and CBII for now as you want to get a feel for what the board is doing.

You will most likely hit the 1.45 volt wall before the cpu temperatures get too hot so get some pics of the settings when you get there.

Reset the bios to stock.

Now do the same with the fsb by just bumping the fsb and the cpu voltage. When it hits the wall then take note of the auto voltages and then experiment with them to see if you can improve anything that way. Fsb overclocking gets very complicated very fast and really doesn't help much with this board.

Reset the bios to stock. Now you are ready for CC and CBII. Start with just the multi and vcore and see how far you can go until you run out of cooling or stability. Then back off one click and see what you can get by adding fsb to it.

I hit a stability wall at 4.9 multi only and only got 20 more with fsb for 4.92 total. Good luck!

Thanks for the advice guys, ill have another go at it later on tonight.

My RAM is a 2 x 4 GB 1600 Mhz Kingston HyperX Blu kit, I have used the Intel Xtreme Memory Profile to set the RAM timings which is 9-9-9-27-36, and the recommended voltage in the XMP profile is 1.65v so I've set it to that.

Ive turned off all the CPU features and eco settings, including Cool n Quiet, ill put that back on once I've found a clock speed that I'm happy with.

So I see how far I can get on just multi and vCore, note it down then reset, then up the FSB and vCore. When I'm doing the FSB method, should I drop the NB and HTT multipliers when the speeds go higher than they should be? I should be keeping the NB around 2200 and the HTT around 2600. Ill be keeping the RAM around its stock values as there isnt much a noticeable benefit to overclocking the RAM, and it was quite cheap stuff so I doubt it will clock up much.

For temperature monitoring I'll use HWiNFO64 and Control Center to keep on eye on temps. For stress testing, should I use IntelBurnTest or Prime95?

Thanks again guys!

Edit:

So I've taken the first step, 4.1Ghz. The vDroop is quite worrying. I set the CPU voltage to 1.377v in the BIOS, and when I got into Windows, it displayed as 1.344v - 1.352v and when I was running IntelBurnTest, the CPU voltage dropped even more, down to 1.304 and occasionally dropped to 1.294. The temps during the test were fine, 45C was the max during the burn test. (Stress Level Setting: Very High and 3 runs).

Its a shame this Mobo doesnt have Load Line Calibration, it would make the voltages more stable/accurate

Wow, that's quite some vdroop. But don't be scared by that. This is more an annoyance for the overclocker, but remember that the CPU doesn't know that LLC exists. It only understands sufficient or not voltage. So as long as it's stable, the vdroop is something annoying, but only you can see it.

My suggestion tp play with fsb was just as much just to learn how to do it as for any practical reason. Indeed faster ram doesn't do much good until one goes over 4.8 ghz.

Don't worry about the vdroop Your voltage at 100% load is about what it should be. Expect to see 0.05-0.08v vdroop as you continue up the ladder. LLC is only useful when you are going for that last little bit of overclock.

Here is where Im at as of now. 4.4 Ghz

The vDroop is quite a lot, I'm currently set to 1.487 which drops to 1.43 at 100% load.



Ill stop when I find 1.45v @ load and see how high it will let me clock it. The temps are okay, 53C load.
post #27 of 29
Good results, congratulations !!

Listen to the good advice of the guys helping you, they know everything about overclocking using AMD hardware.

Anyway 4.4Ghz is a good overclock, perhaps you can reach the 4.5Ghz mark. It´s very noticeable the increase in performance of the FX cpu once overclocked.

Be carefull with your VRM, i know i already said before, but we must take care to avoid burning something.

Good Luck !

Hmm. Either your board has more vdroop than mine or you have a power hungry cpu. I got to 4.6 ghz with the stock bios. But both CPUs have the same VID.

Well anyway, do not pay attention to the settings in the bios but only what it is running at under 100% loads. At 4.4 it should be running under 1.4 volts. The rule of thumb for me is 4.5 ghz = 1.4 volts.

@jclafi This is the GD80. It has the largest best engineered heat sinks of any board I have ever seen. The VRMs do not overheat.

All chips are different. Mine is one super leaky chip and needs 1.48 for 4.5.
