So my AMD 3850 has an Unlocked Multi

post #1 of 15
Thread Starter 
After all the reviews I've read about FM1, I never heard of any saying the multi was unlocked. On my ASUS F1A75-V PRO, I can change the multi to whatever I want, and it sticks. Did I miss a memo? Going to see just how far I can push this little sucker....

Some AMD chips have been known to 'Unlock' to an unlock multiplier.

It sticks in CPU-Z too, not just programs that show exact BIOS values? As far as I know, it shouldn't be unlocked.

If so, share your results

Could be misreading? Do applications show a performance difference (Super Pi, Cinebench)?

I will punch it up and do some Pi runs. Right now I'm trying to get the internet working on it ><

Here is the thread for that discussion.

It's a BIOS bug, CPU-Z is being fooled but the clock frequency actually isn't being increased. Just do some benchmarks at stock and "multiplier overclocked" and you'll see the performance has not changed. Here is a quote from a news article from TechPowerUp about this:

Quote:
Originally Posted by TechPowerUp
"Empty Overclocking" is a term we just made up, to describe unreal overclocking headroom that does not translate into any performance improvements, with AMD's A8-3850 APU. This chip can be set to run at base clock multiplier value above 29x on some motherboards, that will increase clock speed being reported to you, but that "increased" clock speed will not translate to any performance improvements at all.

This means that the multiplier is ineffective in driving the clock above its maximum default value. So the next time you see screenshots screaming something like "6.00 GHz" on air with the base clock at its default 100 MHz, don't be fooled, trust only those overclocking feats in which the multiplier is set at the maximum default (29.0x) or lesser, and in which the overclocker has increased the base clock among other things.

Update: It seems like AMD is aware of the issue, and forewarned reviewers about it. Apparently a glitch in the BIOS code allows the users to "set" higher multiplier values than the chip can respond to, even as the chip doesn't run at those values. Utilities like CPU-Z read those BIOS-set values and display the effective clock speed, even as the actual clock speed doesn't budge. AMD recommends only the base clock increase method for overclocking. As always, AMD warned that overclocked chips are not covered by product warranties. Perhaps future BIOS updates by motherboard vendors will fix this bug.

My 3850 does about the same thing, it will let you pick a multi in bios up to 36X and it will show up on cpuz and in the ASROCK tuning utility as such.
But the frequency stays at 2.9 ghz.
Snappy little processor at any rate, I like it
