M5A78L-M/USB3 with FX6300 - BIOS advice

[madmatt30]

4ghz probly fine mate - may need a voltage or llc bump - may not - depends on the chip.

Try it at 20 multiplier , worst case you'll get a bios post fail or errors in prime.
No problem changing it back again.

Just use the Asus probe software that came with the board yo keep a check on board temps , they're good up to 60c but I'd be happier mid 40s max.

Noted, thanks. What are the values for LLC and in which direction do you change it?

long work day mate.

LLC on this board I have never worked out 100%
It seems the board has pretty bad vdroop which is understandable for a 4 phase ( vdroop is when the voltage actually drops under heavy load)

you will do 4ghz at stock still I think,the board will compensate for the higher clock speed automatically (it wil actually overcompensate fairly heavily) which does mean higher cpu & vrm temps.

essentially run at 4ghz under a prime test at stock - while prime is running check the cpu voltage shown in cpu-z & post that voltage back on here.

As a pointer 66% will stick to whatever manual voltage youve set under load,anything higher you will get vdroop.
33% adds roughly .02v under heavy load,which for me at 4.3ghz means manual bios voltage of 1.36,load voltage is 1.38 under prime - for me thats the best I could do stable which in all honesty is good - I do have a very overclockable chip though.

It will be trial & error for the most part,expect a few blue screens & overclocking failed messages on bios post unless youre very very lucky.

Well at my current manual setting of 19x (3.8GHz), each core pulls 1.288V under load according to HWInfo, which corresponds exactly with P-state P2. P1 and P0 are the Turbo settings, apparently, and they shoot up to 1.3875 and 1.425.

An 80mm fan if you can find a way to mount it flat facing the mosfets will drop temps immensely yes.

Thought I would give a quick follow-up: I tried this over the weekend finally. I did a couple of baseline runs with Prime (10 minutes at a time; that seems to be enough to get all temps to flatline at their peak).

HWInfo recorded the max values as 48C for the CPU itself, and 57-58C for the CPU mobo sensor. Mobo temp is only about mid-30's; not sure which sensor this is.

Anyhow; I then managed to wedge the 80mm fan in flat and quite close to the FET's, no more than 3cm or so away. The result? Nothing. No change in max or average temps whatsoever.

^ there's no reliable sensor for the vrm's mate (I use a infrared thermostat on mine).
That little fan will help though irregardless of readings - trust me on that.
You appear to have a very good voltage on that chip - you could surely push 4.1/4.2 easily.
The Asus is a good little board (better than its comparitive counterpart the gigabyte 78lmt - the heatsinks on that make people assume its better but imo its not at all - it just looks fancier)

So I may have been working off incorrect / incomplete readings? Hmmm... OK, will maybe give it another shot. Thanks!
