Hello eveyone! I am starting a small, but all inclusive owners club for the gimped out A10 and A4 APU, otherwise known as the Athlon x2 340/370 and the Athlon x4 740/50k, and the new 760k/BE. Please know that as these are gimped APU's, they may have a good variance between overclocking chip to chip, as there are some reviewers running the same basic setups, and achieving much higher clocks. I was able to boot to 4.8Ghz, but it was not stable for very long.

==============================================================

Please include a link to your CPU Z Validation for admission! Also, please PM me with the same link, and I will post up an owners list once I receive them.

==============================================================

Most APU OC guides will help you achieve a good clock of up to 4.4Ghz fairly easily, and with the 760k, one should reach the 5+Ghz zone, as the comparable Richland A10 has breached the 5+ Ghz club.

==============================================================

Basic system information:

74c is the absolute maximum recommended temperature for the 740/750k. Expect the same for the 760k.

1.55v is the maximum recommended voltage for the CPU on 740/50k. Expect the same to be true for the 760k.

Stock CPU/NB speed is 1600Mhz. ***Must be raised to a minimum of 2200Mhz for ram over 1866Mhz!!*** Will update once more information is released for the 760k.

1.325v is the maximum recommended voltage for the CPU/NB on the 740/750k. Expect the same for the 760k.

Optimum stable OC for CPU/NB is 2200Mhz. It has been reported to be stable at 2500Mhz, but this will affect overall system clocks/stability.

==============================================================

When you're ready to post information on your CPU, please include the following to help others with settings:

- Motherboard brand, model, BIOS Version and Revision #.

- Multiplier, Bus Speed, Northbridge Clock.

- CPU VCore, CPU/NB Vcore, Vdroop settings, power saving features, and any other applicable settings you used to obtain max stable OC.

- Memory brand, model, OC speed, timings, and voltage.

- Cooling Solution.

- Power Solution.

==============================================================

For optimal Overclocking, it is recommended that you purchase an A85X series motherboard, with good VRM cooling options, as these chips can be punishing on the motherboard!

==============================================================

Please remember to update you're Bios with the most current revision for optimal support.

Time to get the word out and show this sub $90.00 CPU some love!

==============================================================

Wanna show you're love for this CPU? Post this handy dandy code in you're sig!!!

Welcome to the family! And the wolfpack groweth! I will start making an owners list today, and I am pumped to see what you're setup will net you for overall OC-ability.

My new optimum setup, a bit faster all around, save the ram, but the funny thing is, is that it runs faster at it's rated specs, so I am going to try and tighten it up a bit, as running all stock speeds, and with ram set to 1600 but at 7-7-7-23, it screams, it is actually faster than 1866, and is closer to 2133 than running it at 1960 that it was!

Enjoy the deliciousness! My overall goal is to see how stable I can get it, but with the MSI board, although ranks #3 on the ATX A85 offerings currently, and has the coolest VRM's due to the oversized heatsinks and heat pipe, the damned overvolt protection that they added is killing me! OC'ing on this board is taking a painful amount of time, as it fights you after 4.4Ghz. I am working around it and learning as I go, and I do highly recommend the board as it is high on the features, it just sucks being the first one to punish it, and sucks more that MSI decided that AMD couldn't provide the appropriate OV protection on the chips..

BTW, with the Vcore offset to 100%, the board reads 1.568, as this was taken with the CPU at 100% IBT extreme loading, and Bios Vcore was set to 1.500v. The Bios reads the voltage a bit higher than it actually is pulling, as with my multimeter hooked up, I am pulling 1.501v at that loading..

4.5v 12hr stable Prime 95, Small FFT's... I has to go down to stock ram right now, but it is a work in progress! Happier by the minute. The CPUv is 1.55 set in Bios, and it has been checked with the multi at the rail, only 1/100th of a volt off! The trick I found out on this board, is to ENABLE CPU OCP, and CPU/NB OCP. Once the board reads 1.55, it throttles, but if you split hairs with the voltage, it throttles!

You should set your voltage to 1.5v and see if you cant squeeze out a few more Mhz I am sure you could get 4.4-4.5 with out any problems.
These are only 65w cpus so you should be good in volts all the way up to 1.65v.
Just make sure you have proper cooling...
Also you may want to bump up your NB +25 and set it to 2400Mhz that should help a bit.

They claim it has a max safe voltage of 1.55v, but running what I'm running, it is at a temp of 59-61c with p-95 small FFTs. I am sure with solid air cooling, you could push up to 1.7v and be within thermals honestly! Post up all you're system specs and I can give you better help!

How hot does HWmonitor say the VRMs are getting? It'll be the second temp in the system temp section. At 1.55v CPU core, mine runs 63c under load.

It's AUXTIN. That seems normal if its at load when you took the pic. If not, it's about 10c hotter than it could be, but it is dependent on how efficient the cooling is.

Yes your board can handle it as a matter of fact over at anandtech.com they have a review of your motherboard and they claim your mobo is the best for overclocking.
They Overclocked a 5800K to 5.0GHz max and 4.5Ghz for everyday usage.
So if they can do that with a 5800K I am sure you could get 4.5GHz with a 750K!!
I will look for the review for you and post it here.

My Auxtin is always 63c lol, I've never seen it change :s

I think the motherboard that achieved the highest OC was the Extreme 6 version (I have Extreme 4 M as my case cannot take ATX)

Could the VRM temps be Systin? On Asrock AXTU it shows my MB temp which is same as Systin on HWmonitor, CPUTIN is my CPU and the other two are always the same regardless

No love for the 370k?

Thinking of pushing 1.8v like I did with my bd. these high leakage chips love volts.

Your SYSTIN is exactly that, overall MB temp. The VRMs are something that is monitored separately, though also residing on the MB as they get hotter than hell.

And yes, Damric, you can get some love too! Changed title to allow the small tikes in as well.

Welcome, but please do submit a CPU-Z validation on the thread, and the remaining requirements on the first post.

Best temps for me are reflected in my Bios, I can pull up my Bios in Windows, and that gives me a good read while I test. Also, If you use HW monitor, it works, but adds about 10c to the temp, at idle, and shoots up to 120c plus at load, which I believe is bogus, as at 120+, it would go 10 mile island on me. Also, a finger to the side of the CPU tells me that as well.

I would venture to say that the 760 would reach 5Ghz+ easily, as the 5800K doesn't like to go a hair over 4.4, but the 750K reaches 4.5-4.8.

I just looked at your cpuz link and noticed your cpu speed is fluctuating so you need to turn off every power saving feature in your bios such as AMD cool and quiet ,Ciest,Auto anything,power step ect...
The set your ratio to 45 and your cpu voltage to 1.45-1.5v and that will fix all your problems with temps and stability.
