AMD Turbo UCC newbie

Now that I've fixed my overheating CPU problem with some thermal paste, I've gotten curious about exactly how this overclocking works. I haven't really figured out how to turn off the TurboUCC that came with my AsRock motherboard, but I did run the Cinebench CPU test on my computer with the TurboUCC set at the lowest and highest multiplier settings (it runs at the highest setting by default and that's what it's been set on for the last 4 years). At the lowest setting, 4.0, I got a 73 cp score on the cinebench test, but with the setting turned up to 15.0 multiplier, I got a 282 cp score, which was actually higher than the lowest i5 score listed, which was 214, compared to over 800 for a 4-core i7. Is my computer's performance normal for an Athlon II x4 640?

The computer was way slower with the overclocking turned down, so I'm going to leave it set on high, but do I need to do anything about the other settings besides the multiplier? Can I get a simple explanation of the other settings - CPU frequency, PCIE frequency and HT link ratio? I've been searching a lot but it's hard to find much that's specific to the TurboUCC OC Tuner that came with my MB. thanks in advance!!


One other question - I'm still using the ATI Radeon HD 4290 graphics card that comes built into my MB - is that ancient unit slowing anything down, or is it irrelevant to how fast the computer works?

A 4x multiplier would be underclocking. That would mean you set your CPU at 800 MHz.

The stock multiplier is 15x, which gives you the out of the box frequency of 3 GHz.

Can you verify the specific model on the CPU (it might be on the sticker on the box, it's also printed on the CPU itself)?
If you have 'ADX640WFK42GR' then you might be able to ACC unlock some L3 cache and a couple extra cores.

that makes a huge amount of sense and makes it a lot easier for me to understand the readings I get vs. what the advertised speed is. I'll have to check on the cpu model number and get back. thanks for the help!
 
this is the model number that shows on my invoice: ADX640WFGMBOX

from what I can tell the UCC in Turbo UCC stands for Unlock Cpu Cores, so I assume I'm running on all the cores I've got - the processor registers as a 4core/4thread on the cinebench spec readout. I'm a little fuzzy on the L1, 2 and 3 caches. But, if anyone can clear up this whole situation I'd really appreciate it.
 
L1 = fastest, but in small amounts
L2 = slower, but more
L3 = slower, but even more
L3 is the one that "matters" though.
In terms of cores, some AMD CPUs in a certain era would have disabled cores, if they were found to not be 100% perfect. The adventurous, with the right hardware, can unlock these and attempt to increase voltage or downclock GHz to gain stability - and get a much better deal.
Since yours is already a quad core, it doesn't look like more cores are enabled. It doesn't always work, or maybe you didn't click OK somewhere :)
